Description

The present invention relates to a multi-functional pseudo hair thickener, which is well harmonized with human hair, and can be preferably used to conceal the thinned hair portion of the head. In addition to improving the bulky volume that compensates for the lack of hair thinning hair part, combined with negative ion emission and far-infrared radiation, antibacterial and deodorant action, and promoted and improved scalp blood circulation and relaxation effect, and its production Regarding the method.

Since the conventional hair thickening material is a powder or a straight fiber and is only sprayed on the head, it lacks a bulky volume and is inferior in bulkiness for concealing the thin hair portion of the head. Next, pseudo hair thickeners are easy to propagate bacteria during storage with powder, etc., and if you cover the hair thinning part of the head hair with a concealed hair thickener, the occurrence of dandruff, scalp secretions, hair styling agent There was a problem that non-hygiene was unavoidable due to odors such as bacterial growth and dirt due to the adhesion of bacteria. In addition, in addition to improving the bulkiness and volume as if the hair deficient part was inconspicuous and visually increased hair, when given by means of a pseudo hair increaser to make the hair look richer, it is familiar with the scalp, and A comfortable feeling without discomfort is desired. Conventionally, comfort has been obtained by promoting the health of the human body due to the effects of tourmaline and the like. However, the negative ions that are generated are extremely weak and cannot be detected by a measuring instrument. In addition, recent research and the like have known the effect of antibacterial action and deodorant action using negative ions, but since the generation of negative ions is extremely weak, antibacterial action and deodorant action The problem was that there were few effects. In view of such circumstances, the present invention aims to improve the bulky property with excellent bulkiness and volume for concealing the thin hair portion of the head, prevent the propagation of various bacteria during storage, and negative ions. Antibacterial and deodorizing effects are achieved through the sustained maintenance of the emission and the use of far-infrared rays that are emitted at the same time. In addition, the above-mentioned negative ion emission and far-infrared emission effects make it easy to become familiar with the head skin and provide a comfortable feeling of use. An object of the present invention is to provide a simulated hair thickening material. That is, in order to achieve the above-described object, the present invention comprises a pseudo hair thickener having a three-dimensional crimped entanglement structure in the distributed residual hair portion and the like, and the sustainability of the release of negative ions Provided is a pseudo hair thickening material that maintains and uses far infrared rays that are simultaneously emitted.

As pseudo hair or pseudo hair thickening material for concealing the thinned portion of the head hair, various processing of various fiber materials and proposals for imparting functionality to it have been seen. For example, in Japanese Patent Laid-Open No. 5-71003, a separability improving agent is applied to cosmetic fine hair that is fixed to the hair by being sprinkled on the hair or sprayed with a spray. Japanese Laid-Open Patent Publication No. 6-57505 proposes a simple artificial hair material for hair that can be simply fixed to a residue made of a hot-melt short fiber such as polyester and keeps it from falling off. Furthermore, regarding the cutting or pulverization of the fiber material, Japanese Patent Application Laid-Open No. 9-119063 discloses a short napping for cutting or pulverizing fibers having a change in thickness and a different cross-sectional area in the fiber axis direction. A fiber floc and a napped structure using the floc have been proposed. Japanese Patent Application Laid-Open No. 2004-332147 discloses that the first short fibers that are irregular in length and are irregularly mixed are mixed to obtain a volume feeling with a high bulkiness and a small amount. Artificial hair fibers that use and methods for producing artificial hair fibers are described.
In addition to the spread of antibacterial deodorization in recent daily necessities, Patent No. 3035279 includes either a polymer compound that is not easily charged with static electricity, a mineral containing rare elements, and at least one of tourmaline or far-infrared radiation ceramics. Resin composition that emits negative ions at the same time that emits negative ions including one, and as a non-patent document, photo-catalytic effect that titanium oxide of several to several hundred nm called photocatalyst hits the ultraviolet rays of sunlight. Excited by electrons, electrons and holes are generated. Electrons reduce oxygen in the air to superoxide ions, and holes oxidize surface moisture to hydroxyl radicals. The superoxide ion and hydroxyl radical exhibit strong oxidizing power, and when an organic substance adheres to the titania surface in this state, the superoxide ion decomposes the organic substance carbon and the hydroxyl radical takes hydrogen. Such a self-cleaning action is a mechanism that becomes an antibacterial action and a deodorizing action. Proposals for imparting functionality to artificial hair have been seen, and Japanese Patent Application Laid-Open No. 9-119063 describes antibacterial fine hair produced by a wet spinning method containing chitosan. . Furthermore, Japanese Patent Application Laid-Open No. 2003-119608 discloses a combination of a spraying adhesive and a short fiber which is obtained by pulverizing a natural ore containing a radioactive rare earth element, mixing it into a raw material for artificial hair, and dividing it into a fine filament. The hair thickening material which consists of is proposed.
In the artificial hair follicle obtained by mixing two or more kinds of colored fibers having different hues (Japanese Patent Laid-Open No. 2001-200415), the applicant has 0.01 to 45 parts by weight of the dye with respect to 100 parts by weight of the cellulose fiber. Pseudo follicles that are dyed in such a manner as described above, and fuzzy follicles that are suitable for concealing the thin hair of the head (Japanese Patent Laid-Open No. 2001-254216) In addition, in Japanese Patent No. 4822086, there is a proposal of a multifunctional pseudo hair-raising material with improved dispersibility, and in JP 2012-26070 A, a multifunctional pseudo hair thickening material, In all of the four cases, the fiber length is 0.1 to 5 mm and the fiber diameter is in a numerical limited range of 0.50 to 30 denier. In the present invention, the cellulose fiber is equally used as the main fiber. In the fiber length of the main shaft fiber, at least the fiber length in the above-mentioned prior application is 5.00 mm in the upper limit value. In the present invention, the fiber length value does not exceed at least 1.00 mm. It is a limitation of the low numerical range (fiber diameter is not changed from 0.5 to 30 denier), and the problem to be solved is an invention relating to an improvement in which a bulky volume feeling is improved in the artificial hair thickener.
In the proposals as described above, the hot-melt short fiber polyester and the like can be simply fixed and held for a simple artificial hair material of the hair, and further, regarding the cutting or crushing of the fiber material, the short fiber flock for napping and polyester as the napped structure This is a proposal for crimped yarn. It describes that rayon is heavy, has a low fastness to wet friction dyeing, is inferior in thermal stability, and has limited applications in cellulose fibers. In addition, artificial fibers in which the first short fibers that are not uniform in length and are irregularly bent are mixed with the straight second fibers that are constant in length, and are extremely bulky due to their combined form, and in small volumes. It cannot be said that a feeling is obtained. In addition, the antibacterial properties are limited to preventing the propagation of various germs during storage, but when using a simulated hair thickener on the thin hair of the scalp, before washing it away, it is easy to shampoo later. Sustained antibacterial and deodorant functions are desired due to unsanitary odors such as bacterial growth and dirt due to the attachment of scalp secretions and hairdressing agents. In addition, its functionality is not limited to the range where functions such as antibacterial deodorization can be imparted, and its function, including atmosphere and environmental factors such as negative ion emission and far-infrared radiation, can also be used as a neat and sensation mood on the thinning hair of the head. This is an aspirational issue that needs to be addressed in areas where it is possible to further impart and exhibit sex.

An object of the present invention is to solve the above-described problems. First, in order to achieve the above object, (1) the present invention achieves the above-described object by providing a three-dimensional wrinkle on a distributed residual hair portion or the like. There is provided a pseudo hair thickening material comprising a hair thickening material having an improved bulkiness having a tanned structure, maintaining the release of negative ions, and simultaneously utilizing far infrared rays radiated. (2) In the configuration of the present invention, the cellulose-based fiber that has been used as a pseudo hair material for a long time has a small amount of water-soluble substances in the fiber and effectively utilizes the characteristics excellent in moisture absorption and water absorption. It can be dyed so as to have a color and luster that harmonizes with human head hair, and it does not look like white hair due to the transmission of light rays, harmonizes with human head hair with natural luster, and Cellulose fibers selected from those that can exhibit the attributes of natural fibers with excellent concealment properties for thin hair parts are the main constituent parts of the artificial hair thickener composition, especially bulky suitable for concealing the thin hair parts of the head It is possible to easily and effectively manufacture a pseudo hair thickener with improved properties. Needless to say, in the present invention, cellulose fiber has a small amount of water-soluble substance in the fiber as its main shaft fiber, and it effectively uses the characteristics of moisture absorption and water absorption, and it is friendly to human skin. The cellulose fiber used is a main shaft fiber. (3) The next solution is that the human head tends to become unsanitary due to odors such as bacterial growth and dirt due to the occurrence of dandruff, scalp secretions, and hairdressing agents, and also prevents the propagation of germs during storage. In addition to providing antibacterial and deodorant functions for the purpose of the treatment, the spraying or sprinkling of the head thinning hair area promotes blood circulation that is advantageous for hair growth or hair restoration promotion on the scalp due to its reducing action, It is desirable for the thin hair part to make the atmosphere environment at the head good and relax by the synergistic effect of the negative infrared radiation action that is said to also exhibit the negative ion release environment at the scalp site and / or the further excitation phenomenon of the photocatalytic antibacterial deodorizing action. A pseudo hair thickening material suitable for concealment can be obtained. Further, in the present invention, in order to improve bulkiness, a hot air stream dryer is used, and fine short fibers are sprayed in a substantially inclined manner by spraying air on the main shaft fiber coated with an aqueous binder having adhesiveness on the peripheral surface thereof. In this configuration, the interlaced interlaced fibers form a three-dimensional structure of interlaced fibers, and the contact points between them are bonded and fixed to form a cross-linked or interlaced configuration. It works to function in a synergistic effect combined with bulkiness.
As described above, in the present invention, it is an improvement in bulkiness composed of a hair thickening material that forms a chordal loop entanglement structure based on a crimp deformation factor in a distributed residual hair portion, etc., and maintains the sustainability of negative ion release. In addition, a pseudo hair thickening material that utilizes far infrared rays that simultaneously radiate is provided. In other words, in order to conceal the thin hair part of the head, the bulky volume is improved and the antibacterial effect is enhanced by the prevention of breeding of germs during storage and the use of far-infrared rays emitted simultaneously with the release of negative ions. In addition, the deodorizing effect is achieved, and the negative ion emission and the far-infrared radiation function together make it easy to become familiar with the skin of the head and provide a comfortable feeling of use. In addition, the dispersion formulation of the above-mentioned inorganic fine particles works as matte fine particles, gives a heavy texture in harmony to the hair of the damaged thin hair, and makes it more natural hair even when it is glossy under direct sunlight An object of the present invention is to provide a pseudo hair thickener that exhibits the above-described effects.
In order to achieve the above object, the present invention has a cellulose fiber as a main axis, the cellulose fiber is within a fiber length of 1.00 mm, and has a fiber diameter of 0.5 to 30 denier. The short fibers having a substantially constant length are selected from at least the same type or different types of fibers as the cellulose fiber, and the fibers are preliminarily 8.0% crimped with the same type fibers and 11% crimped with the different type fiber polyamide. , 5%, 12% crimped deformation pretreatment with the same polyester , and the desired short ratio of fine short fibers cut and pulverized to 60% or less of the cellulose fiber length in the fiber axis direction In the first step, the bulkiness is improved by utilizing the residual shrinkage of the fiber that expresses the potential characteristics of the main shaft fiber and the microshort fiber for the bulkiness. Dry heat Next, in the subsequent stage process, a water-based adhesive containing a soft component based on a synthetic resin emulsion is used for the bonding process of the mixed entangled contact between the main spindle fiber and the micro short fiber, and hot air In a passage that is air-conveyed by an air current, the micro-short fibers are sprayed at a substantially inclined angle on the heat-adhesive adhesive layer in which the water-based adhesive is coated on the peripheral surface of the main shaft fiber to form an intersection. Multi-functional fake hair that has a three-dimensional structure of interlaced fibers that are entangled with each other by bonding and fixing contacts, and that can improve bulkiness in combination with dry heat shrinkage by using residual fiber shrinkage in the previous stage It is a structure of a hair thickener.

According to the present invention, the cellulose fiber having excellent moisture absorption and water absorption properties is used as the main shaft fiber, and in the second step, after the fiber is cut, selected and sieved, the color and glossiness that matches the human hair are obtained. In the second step, in addition to the dry heat shrinkage treatment using the residual fiber shrinkage, fine short fibers are applied to the binder adhesive resin layer on the peripheral surface of the main spindle fiber using a hot air dryer by spreading air. The chord form that forms a three-dimensional structure of the fiber by bonding the crossed contacts that are sprayed in an incline and intertwined, and the holding and pushing of the third substance such as fine animal hair is centered between the main fiber Since the distance increases, it is possible to improve the bulkiness by improving the bulkiness at the critical limit. Furthermore, in the above-mentioned chordal form, the presence of air passages, and the combination of powders of inorganic fine particles such as negative ions and far-infrared radiation materials with minerals containing rare elements for imparting antibacterial and deodorant properties may cause damaged hair parts. It gives a heavy texture to the hair and allows for finer adjustment of luster, reducing the sense of discomfort with the hair.

The present invention is a pseudo hair thickener that is sprayed or sprinkled on the thin hair portion of the hair, etc., the cellulose fiber as the main axis of the pseudo hair thickener, the same kind of cellulose fiber or a different fiber, such as polyamide, polyester, and the like, and These fibers are preliminarily subjected to pre-crimp deformation treatment of 8.0% for the same type of fibers, 11.5% for the dissimilar fiber polyimide, and 12% for the same polyester. In the same kind of cellulose fiber, the bulkiness is improved by the composition of the pseudo hair thickener composition which is mixed with the main fiber at a blending ratio of at least 15 % by weight in the case of the same type cellulose fiber and at least 15 % by weight in the case of the different types of different fiber polyimide and polyester. Furthermore, in the present invention, the composition exhibits the potential characteristics of the main fiber and the short fiber for bulkiness. In order to improve the bulkiness utilizing the residual shrinkage of the fibers to be formed, a dry heat shrinkage treatment is applied. In addition to this, in the adhesion treatment of the mixed entangled contact between the main shaft fiber and the minute short fiber, a synthetic resin emulsion In a passage through which hot air flow is conveyed using a water-based adhesive containing a soft component based on the heat-sensitive adhesive layer in which the water-based adhesive is coated on the peripheral surface of the main spindle fiber, the fine air is applied to the heat-adhesive adhesive layer. The short fibers are sprayed at an angle of inclination to form an intertwined cross contact, and the interlaced interlaced interlaced fiber interlaced three-dimensional structure is formed by using the residual shrinkage of each fiber. It is the composition of a multifunctional pseudo hair thickener composition characterized by being able to improve bulkiness in combination with dry heat shrinkage. In addition, in the bonding treatment of the crossing contact in the above-described entangled interlaced fiber crossing three-dimensional structure, a flexible component based on an acrylate copolymer emulsion is used as an adhesive of the smallest possible amount necessary for bonding. Main axis fibers and micro short fibers by using as little adhesive as possible to suppress contact with the resin, which suppresses resin hardening and fiber rebound resilience that hinder bulkiness after bonding. It is appropriate to form a three-dimensional three-dimensional fiber interlaced structure that is entangled with each other.
By the way, in general, processing for imparting bulkiness by fiber processing is performed by, for example, giving a natural fiber-like crimped form typified by wool to a chemical fiber yarn mainly composed of synthetic fiber to give the texture of the chemical fiber. Bulky processing to improve and impart bulkiness is performed. In other words, the bulking process imparts bulkiness by imparting two-dimensional or three-dimensional crimps to the yarn, fixing this distortion and disturbing the parallelism between the fibers, and the swirling bulkiness of the thermoplastic synthetic fiber. Processing is a typical processing method. However, in the pseudo hair thickening material that is a microfiber, first, for example, when short fibers subjected to crimp deformation treatment have a problem of bulkiness, entanglements and hairballs are generated from the form, and dispersibility In terms of this, it was found that there are decisive obstacles. In general, bulky processing with processed yarn is also known as a conventional means and is well known to those skilled in the art, but if this is to be applied to a pseudo hair thickener, it is inevitable that the fibers will be entangled with each other and this solution is premised. It becomes.
For this reason, in the present invention, first, the first problem is to avoid the same length and the same diameter in one of the fibers as compared with the straight main axis cellulose fiber that is not pre-crimped as the main axis. The fiber is preliminarily crimped with a crimp rate of 8.0% for the same type fiber, 11.5% for the dissimilar fiber polyimide, and 12% for the same polyester , and the fiber length in the vertical axis direction is preferred. A pseudo hair thickener composition that is cut and crushed after controlling to a ratio, for example, 60% or less, and mixing them, and the second problem is that the ratio of blending the crimped and crushed fibers is a desired ratio, for example, in the crimping has been performed rayon, the range of the blending ratio of 20 wt% or more. Also, polyamide crimped has been subjected, in the synthetic fiber of polyester, and also due to its attributes, and compounding ratio 15 wt% or more, by combining those satisfy these two conditions, i.e. the first object For example, entanglement of at least uncrimped straight main spindle fiber and one crimped fiber, overcoming of incentives for inhibition such as dyeing unevenness, etc., together with the second problem, which is preliminarily crimped and deformed In order to solve the problem of bulkiness, the mixing ratio of blended fibers including coiled, bent, curled, coiled, etc. due to the impact force of the rotary blade and the shearing force in the horizontal direction during grinding There is a critical significance of quantitatively limiting. As described above, in the present invention, improvement of the bulkiness is a problem to be solved. First, the crimped blended fiber employed as a deformation processing means has a desired fiber length that is differentiated from the principal rayon fiber even in the fiber length. Controlled cutting and pulverization, and secondly, the blending ratio of crimped short fibers also works to improve bulkiness by a preferable blending ratio, and in the present invention, cellulose fiber is the main axis, and the same kind Or, when mixing with different kinds of micro short fibers, searching for elements contributing to at least bulkiness with different specific physical properties in each fiber, there is a difference in the presence of dry heat shrinkage and its numerical range in each fiber In addition, for example, even in the mixed form of two types of fibers having different fiber lengths, a certain bulkiness can be seen. With improved bulkiness act as a scaffold to strut elements in concrete bodies, together discovered that serve to contribute to the space forming an air passage through which air flows in the structures, we have reached the present invention.
The present invention consists of a mixture of cellulose-based fibers in the remaining hair portion, etc., which has been distributed, with micro short fibers that have undergone pre-crimp treatment, and first, the residual shrinkage of the fibers that develop the respective potential characteristics. A dry heat shrinkage treatment is applied for the bulkiness used, and then the short contact fiber is sprayed on the adhesive resin layer on the peripheral surface of the main spindle fiber using a hot air dryer to form a cross contact. It is a configuration aiming to improve and improve the bulkiness composed of a hair thickening material that forms a tangled interlaced form that forms a three-dimensional structure of fibers by adhesion, and the three-dimensional structure of the three-dimensional structure has air passages. It is a structure of a pseudo hair thickener that is suitable for the purpose of maintaining the sustainability of negative ion emission and utilizing far infrared rays that are simultaneously emitted because of the existence.
The present invention is a pseudo hair thickener that improves bulkiness and has an excellent bulkiness for concealing the thin hair portion of the head, and is a dry heat shrink treatment for bulkiness utilizing residual shrinkage of fibers. Subsequently, a hot air dryer is used to bond and fix the main shaft fiber and the micro short fiber so that the micro short fiber is substantially inclined in the binder adhesive resin layer on the peripheral surface of the main shaft. It is possible to use a hot-air dryer to bond and fix the crossed contacts that have been entangled with each other by using a hot air dryer, and it is a composition of a hair thickener composition of a fiber interlaced structure that forms a three-dimensional fiber structure. .
In the present invention, first, the pseudo hair thickener composition having a cellulose fiber as the main axis is a range in which the cellulose fiber does not exceed a fiber length of 1.00 mm, and has a fiber diameter of 0.5 to 30 denier. Is selected from at least the same type or different types of fibers as the cellulose-based fibers, and the fibers are preliminarily subjected to crimping deformation pretreatment, and the length in the fiber axis direction is set to the cellulose. This is a structure of a pseudo hair thickener in which fine fibers cut and ground to 60 to 80% or less of the system fibers are mixed in a desired ratio. In producing the composition, in the first step, the raw material yarn is received, cut into a predetermined length, cut / screened, dyed, dispersed, and dehydrated. In the present invention, in order to further increase the bulkiness, in the present invention, after the above hot air drying, product inspection / shipment product is not performed, and it is directly connected to the first step of the second step. In the first stage of the second step, hot air drying, preliminary air drying (stirring / dispersion), and dry heat shrinkage are performed, and in the latter stage, the main shaft fiber and the micro short fiber are tangled and bonded at a crossed contact point. By fixing, the strain is fixed by crimping by dry heat shrinkage treatment in the previous step, and the parallelism that is disturbed by the mixed entanglement between the main spindle fiber and the micro short fiber is fixed, and the tertiary The composition of the fiber crossing structure forming the original structure Is shall. Furthermore, in order to improve the bulkiness, if necessary, spray adhesion treatment by holding and pressing at least one third substance selected from finely crushed animal hair, fine urethane powder, and microcapsule is performed. Rare elements mineral powders are mixed in, followed by hot air drying, product inspection and shipping process. First, regarding the dry heat shrinkage treatment in the first stage of the second process, the cellulose fiber and the micro short fiber of the main shaft fiber are the same, but the polyamide and polyester fibers are heterogeneous fibers and are dried in the previous stage. In heat shrinkage crimp, there is a disparity in dry heat shrinkage due to the use of residual shrinkage between these fibers, but in the structure of entangled fiber interlaced three-dimensional structure, the unevenness of crimp works to act as a factor of improving bulkiness It seems to be a cross contact where the short short fibers are tangled and tangled by spraying at a substantially inclined angle, by stirring and dispersing in the latter stage, and by bonding and fixing the cross contact points in the form of entanglement between the main shaft fibers and the short short fibers. In the bonding of each fiber, the disordered parallelism between the fibers is fixed in a tangled and interlaced form, and the fibers are entangled with each other to form a tangled fiber-interlaced structure. Dry heat yield by using shrinkage It serves to obtain aim to improve bulkiness.
Regarding the dry heat shrinkage treatment in the first stage of the second step, first, regarding cellulose fiber and viscose rayon, which are the main shaft fibers in the present invention, Daiwabo Rayon Co., Ltd. also adopted in Examples 1 to 4 of the present invention. In the test results of the above, it is assumed that the heat shrinkage of the rayon is perturbed, and the test method, JIS 1015, 7151, is the test fiber length method of 20 mm, 25 mm, 50 mm, the test fiber length is too short and the error is large, and 50 cm After refining the tow, it was used as a sample, and the measurement was carried out with a test length of 15 mm as read by the casetometer. As a result, dry heat shrinkage was also observed in rayon, but it was easier to shrink when wet, and the dry heat shrinkage rate was 2.11% under conditions of dry heat of 150 ° C. × 20 min. It was. However, it is considered that the fiber once shrunk is stabilized from the structure and becomes a fiber with stable heat fluctuation. For synthetic fibers other than rayon, for acrylic fibers, the dry heat shrinkage treatment means the shrinkage at 100 ° C. dry heat, specifically, the test length under 10 mg / decitex load (L _W ) was measured, and the shrinkage was caused to shrink in a convection oven by dry heat treatment at 100 ° C. for 30 minutes, then returned to room temperature, and the test length (L _W ) under 100 mg / dtex load was measured. Find the rate.

Dry heat shrinkage rate (%) = ((L _W −L ｀ _W ) /) × 100
Also, the dry heat shrinkage treatment temperature is 1% or more at a dry heat of 80 ° C, 2% or more at a dry heat of 90 ° C, and 10% or more at a dry heat of 110 ° C, and the shrinkage varies depending on the treatment temperature. I will do it. For example, in the case of a fiber made of an acrylic polymer containing 30% by weight of acrylic, there is a numerical example of a dry heat shrinkage ratio of 5% or more at 100 ° C. for 30 minutes.
In the latter stage of the second step, after the stirring and dispersion, the adhesive treatment of the contact in the form of entanglement and intersection between the main shaft fiber and the minute short fiber, the synthetic resin emulsion is used as an adhesive of the smallest possible amount necessary for adhesion. Can be selected from at least one selected from the group consisting of an acrylate copolymer emulsion, an acrylate polymer resin emulsion, a vinyl acetate resin emulsion, and a vinyl acetate copolymer resin emulsion. In this case, an acrylate copolymer emulsion is used, and the amount used is an adhesive fixing of the cross contact in the form of entanglement between the main shaft fiber and the minute short fiber. Contact bonding using a small amount of adhesive is suitable. In the present invention, the coating amount of the adhesive is low in the fiber length of the micro short fibers and differs depending on the particle size of the resin component, but the coating amount of the adhesive is 8 to 10 g / m ² as the resin solid content. , preferably 5 to 7 g / ^{m 2,} more preferably at 3 to 5 g / ^{m 2.}
An air flow dryer (ACD type manufactured by Kumeta Co., Ltd.) used as an embodiment of the present invention is shown in FIG. The airflow dryer main body 8 communicates with the carrier air from the air heater 9 and supplies a first hopper a10 for supplying the spindle fiber 2, then a second hopper b11 for spraying fine short fibers by spraying air and the hopper 10 And a third hopper c12 for supplying a third substance 4 such as fine animal hair, which is communicated by a drying pipe 17 and is separated from the eyelid, and an exhaust fan 18 which is arranged to be communicated through the drying pipe 17 It is mainly composed of a cyclone 19 to be connected. In said 1st hopper a10, the adhesion layer by which the adhesive acrylic ester copolymer emulsion was beforehand coated on the surrounding surface of this main axis fiber 2 was formed, and the position which provided the slight time difference in which hot air dry air current is conveyed In the hopper b11 attached to the hopper b11, an air compressor 16 is provided in the hopper b11 in order to spray and bond the micro short fibers 3 in an inclined manner to the adhesive layer formed on the peripheral surface of the main spindle fiber 2. The third hopper c12 is a hopper that supplies one kind of the third substance 4 selected from fine animal hair, fine urethane powder, and minoro capsule as described above. In order to hold the third substance in an indented state in the entangled fiber crossing structure after the short fibers, it is possible to adopt a configuration in which a spraying mechanism for spraying air is provided if necessary. Further, in the mixing of the rare earth element mineral particles 5 in the present invention, the third hopper c12 can be used and charged at the same time as the third substance 4 is pushed and held by the spraying air. 13 is a rotary valve a, 14 is a rotary valve b, 15 is a rotary valve c, 20 is a rotary valve d, and 21 is a discharge port.
Next, FIG. 2 shows the main shaft fiber 2 and the micro short fiber 3 for producing the fiber interlaced structure according to the present invention in the airflow dryer used as the embodiment of the present invention in FIG. It is explanatory drawing which shows transition in the adhesion | attachment state in the entanglement crossing-like contact. In FIG. 2, an adhesive made of a tacky acrylic acid copolymer emulsion is coated in advance on the peripheral surface of the main spindle fiber 2, and hot air is supplied to the drying pipe 17 from the hot air generator 22 in the airflow dryer body 8. An airflow is being conveyed, and firstly, the main spindle fiber 2 whose peripheral surface is in an adhesive state is discharged and supplied from the first rotary valve a13, but at least the peripheral surface of the main spindle fiber 2 is maintained with a slight time difference. At this stage, the short microfibers 3 that are sent by the carrier air and dried are desirably entangled with each other by the spraying means, that is, in the state where the parallel lines of the interlaced relations are disturbed. The stage of the adhesion fixation in the crossing contact in the mutual in the process of forming the fiber crossing structure by the adhesive fixing of the crossing contact is shown. Further, in the lower part of FIG. 2, as described above, the adhesive unprocessed micro short fibers 3 are entangled with the main fiber 2 coated with the adhesive acrylic resin copolymer emulsion from the first rotary valve a13, preferably by spraying. At least one third substance 4 selected from among micro animal hair, urethane powder, and microcapsule is preferably used in the crossing state, and preferably, when the adhesive is still in the state of maintaining the adhesiveness, Desirably, it can be a fiber interlaced structure having an entangled three-dimensional structure held by injection pushing. In the figure, the fiber crossing structure 1a (no indentation holding of the third substance) in the present invention is composed only of the mixture of the main fiber 2 and the short microfiber 3, and the rare element mineral powder 5 is mixed therewith. Further, in the fiber crossing structure 1b (with the third substance pushed in), the third substance selected from the main spindle fiber 2, the micro short fiber 3, and the fine animal hair is used. A mixed fiber structure in which rare element mineral powders 5 are mixed, 6 is a gap, and 7 is a cross contact.
In the present invention, an adhesive is used to bond and fix the interlaced contact points between the choroidal fibers. However, there is an embodiment in which the amount of use cannot be avoided as a premise of the solution by using the adhesive. In the present invention, an adhesive resin adhesive based on an acrylate copolymer emulsion is used as an adhesive, and the aqueous adhesive is applied to the peripheral surface of the main shaft fiber in a passage that is air-conveyed by a hot air stream. The coated heat-adhesive adhesive layer is formed by spraying minute short fibers at a roughly inclined angle on the coated heat-adhesive adhesive layer to form an interlaced fiber three-dimensional structure that is entangled with each other by adhesive bonding and fixing. However, in the water-based adhesive based on the water-soluble resin in the present invention, in the limited solution to the use of the adhesive, that is, in the mixing of the main spindle fiber 2 and the microshort fiber 3, first, The fine short fiber 3 is pierced or cross-linked at the cross contact 7 by hot air conveying air to the adhesive adhesive layer in which the peripheral surface of the main spindle fiber 2 is coated with the aqueous adhesive. Fixing is achieved, but it is only necessary to achieve mutual fixing of the fibers at the crossing contact point instead of a resin coating that covers the entire entangled form of both fibers. is there. For this reason, if the amount of use is increased even when the cross contact 7 is bonded and fixed, there is a possibility of covering the existence of voids or gaps in the three-dimensional structure of the fiber cross structure 1a, 1b. While suppressing, it is preferable to advance the adhesion fixation at the cross contact 7 by adding a curing accelerator in advance, for example, even if the amount of the water-based adhesive is small. For this reason, in the present invention, in order to suppress the amount of the adhesive used, the curing is progressed even with a small amount of water-based adhesive to achieve the adhesive fixing of the cross contact 7, and the adhesive is preliminarily set in the adhesive. It was set as the structure which functioned so that it might function complementarily also with respect to suppression of the usage-amount of an adhesive agent. In the adhesive technology, curing means thermal curing, a cross-linking reaction occurs in the adhesive, forming a three-dimensional fiber three-dimensional structure, becoming insoluble and infusible. In the method using an adhesive by bonding two adherends and adhering them to such an extent that they can withstand a considerable pulling force, the fixing reaction of the bonded portion is the fixing in the adhesive layer, the adhesive and the covering. It can be divided into fixing at the contact interface with the adherend, and curing is a term used for fixing at the adhesive layer. Fixing at the adhesive layer means that the fluid adhesive is used for physical reaction or It is solidified by chemical reaction. For example, polymethyl methacrylate is a thermoplastic resin, and dimethylaniline accelerator is a decomposition accelerator for benzoyl peroxide mixed with polymethyl methacrylate as an adhesive, and can be cured by a crosslinking reaction. The functional acrylic resin is a thermoplastic resin, and is cured by causing a crosslinking reaction with a curing agent. Since the curing agent is a general term for those that cause the curing of the adhesive and those that accelerate the curing, the dimethylaniline accelerator is included in the category of the curing agent. The use of an agent promotes curing by mixing an adhesive curing agent in advance.

In the present invention, as described above, in order to impart functionality such as antibacterial and deodorant properties, a mineral containing rare elements, and a mixture containing either one of tourmaline or far-infrared ceramics are added and mixed to release negative ions. In addition to antibacterial and deodorizing properties by far-infrared radiation, blood circulation promotion and relaxation effects, it is expected to have an advantageous effect on hair growth or hair nourishment in the thin hair portion of the hair. Here, in the present invention, the following further effects are expected. That is, human hair is desired to have a texture and luster that are in harmony with the hair at the thin hair portion, although there are individual differences. First, in the present invention, the main fiber is a cellulose fiber, and the same or different pulverized fibers to be combined by pre-crimping have a difference in blending ratio, and the dyeing process is one. It can be dyed by either bath or two baths.
By the way, in the present invention, the addition and mixing of the minerals (inorganic minerals) and the far-infrared emitting materials (ceramics) containing the rare elements described above is not a lepel that gives a desired effect and impairs the texture and physical properties. Even the dyeing process that seeks a harmonious texture and gloss does not become an impediment. On the other hand, in the present invention, the mineral containing the rare elements and the far-infrared emitting material, that is, the former inorganic mineral powder and the latter ceramic are both inorganic fine particles, and a pseudo hair thickener composition in which these are dispersed and blended. Then, it gives a heavy texture to the hair in the thin hair portion of the damaged hair, and the gloss can be adjusted more finely. In general, rayon and polyamide fibers have a drawback that even if they are dyed with relatively high transparency, the hair after spraying or sprinkling tends to look white hair due to the transmission of light, and there is not much qualitative discomfort with the hair. In addition, the desire to make the hair look softer and richer always changes. Also from this point, in the present invention, the addition and mixing of the mineral (inorganic mineral) containing rare elements and the far infrared radiation material (ceramic) is not limited to the effect of negative ion emission and far infrared radiation, With regard to the solution problem, the present invention is characterized in that a separate effect is achieved. Here, regarding the safety of minerals containing rare elements, radiation of 1.0 mu Sv / hr or less, which is said to emit extremely weak radiation and not adversely affect the human body, etc., is used in the present invention. The use of the artificial hair thickener is safe from the generation level of radiation.
Therefore, in the present invention, because it gives a texture and gloss harmonious with the hair at the thin hair part, gives a heavy texture to the hair at the damaged hair thin hair part, and contributes to finely adjusting the gloss, In addition to minerals (inorganic minerals) and far-infrared radiation materials (ceramics) containing rare elements, pseudo hair growth with 1-20% by weight, preferably 1-10% by weight, of the following inorganic fine particles: It can be set as a material composition.

As special fibers, synthetic fibers or fibers containing rayon and vinylon containing photocatalytic titanium dioxide, apatite-coated titanium dioxide, and inorganic ceramic-containing titanium dioxide can be used. Most preferably, a synthetic fiber selected from polyester, polyamide, acrylic, vinyl chloride, polyolefin, aramid, urethane, polyacrylonitrile and the like has higher rigidity and is beneficial for improving bulkiness.
In the present invention, as minerals containing rare elements, ferrugsonite, monazite, xenotime, columbite, betajolite, samarsky stone, eucsenite, tantalum stone, sphalerite, thorium stone, rubber stone, carnotite, gadolin There are stones. Among these ores, monazite can be most preferably used as one that emits extremely weak radiation and does not adversely affect the human body, and as a mineral that excites negative ion emission. As the particle size of the natural ore, those pulverized from 0.1 micron to 1 mm can be used. Most preferably, a powder whose average particle size is pulverized to 10 microns or less is better and better mixed and coated. As the above-mentioned blending part, 50:50 parts by weight with respect to the far-infrared emitting substance is beneficial in that it releases more negative ions.
In the present invention, as tourmaline, shoal tourmaline, lithium tourmaline, drabite tourmaline, rubellite tourmaline, pink tourmaline, indecolite, baraiba tourmaline, watermelon and the like can be used. As the particle size of the tourmaline, those pulverized from 0.1 micron to 1 mm can be used. Most preferably, the average particle size is 10 microns or less. As for the number of blending parts, 50:50 parts by weight with respect to the rare element mineral is useful for emitting far-infrared rays.
In the present invention, a far-infrared ceramic that radiates far-infrared rays having a wavelength of 2 to 50 microns can be used as the far-infrared ceramic. As a far infrared ceramic component, a mixture containing two or more kinds of alumina, silica, zirconia, sodium oxide, magnesium oxide, iron oxide and the like can be used. Examples of the commercially available products include the product name Serajit and OK Trading, which are suitable for amplifying negative ions and emitting far infrared rays. As said compounding part number, 50:50 weight part is useful when radiating a far-infrared ray with respect to a rare element mineral.
In the present invention, as the photocatalytic functional material, any of anatase type titanium dioxide, brookite type titanium dioxide, apatite-coated titanium oxide, titanium dioxide including inorganic ceramic, and the like can be used. The anatase-type titanium dioxide and brookite-type titanium dioxide having a particle size of 5 to 200 nm can be used. Most preferably, 6-30 nm is more beneficial for exciting electrons.
As the apatite-coated titanium dioxide, it is possible to use the titanium dioxide coated with apatite, that is, calcium phosphate.

The present invention is a structure of a pseudo hair thickening material in which cellulose fiber is used as a main axis and mixed with the same crushed fiber that has been crimped in advance, so that the human hair has a harmonious color and gloss. It can be dyed, in particular to improve the dispersibility during the production process and in use, and the ultimate is an increase in bulkiness and bulkiness with excellent concealment. In addition to the fleece or vertical or slanted shape of the main shaft fiber, the main shaft fiber has crossed, right-angled, bridging entangled, coiled, etc. Therefore, a deformed or crushed bent, curled, crimped or the like forms a three-dimensional three-dimensional structure that is connected and interlaced, and works to form a bulky volume and excellent concealment.
In the present invention, in addition to the structure of the fiber cross structure having a three-dimensional structure as described above, a foaming agent is added to and blended with the simulated hair thickener composition so as to contribute to an improvement in bulky volume and concealment. Examples of foaming agents for forming foams include azodicarbonamide, azobisisobutyronitrile, dinitropentamethylenetetramine, 4.4 oxybisbenzenesulfonyl hydrazide, paratoluenesulfonyl hydrazide, baking soda, gas-filled microcapsules, etc. Either can be used. The blending amount of the foaming agent is 0.1 to 20 parts by weight, preferably 1 to 10 parts by weight with respect to 100 parts by weight of the simulated hair thickener composition.
In the present invention, the adhesive has good adhesiveness, water resistance, and flexibility, but is not a solvent type that has flammability and toxicity, and an aqueous solution type adhesive including an emulsion type is adopted, and there is no flammability and toxicity. However, since the adhesive strength is not sufficient, a cross-linking agent is used together. However, in terms of flexibility and adhesiveness, it is a reactive and self-crosslinking adhesive in which an acrylic monomer having a reactive group is copolymerized and has a viscosity of As an alkali thickening type that can be adjusted sufficiently, the adhesive strength is enhanced by the combined use of a melamine-based crosslinking agent. Next, in the post-treatment, the mixed entangled cross-bonding treatment between the main spindle fiber and the microshort fiber, the water-based adhesive based on the water-soluble resin is used as the main component, an acrylate copolymer resin emulsion. It is not necessary to use a small amount of adhesive for the adhesive treatment at the intersection, and it is possible to cross-connect the three-dimensional fiber interlaced structure formed from the main fiber entanglement at the rear stage in a tangled shape. The role of the adhesive is only to adhere at the crossing contact point. When the adhesive is further applied, not only does it block the space for ventilation in the structure, but also the structure is solidified. It is not preferable because it may be a factor. The amount of the sticky adhesive used for coating the peripheral surface of the main spindle fiber by hot air treatment is such that the micro short fibers are pierced into the adhesive adhesive layer of the coating on the peripheral surface of the main spindle fiber by hot air conveying air. It suffices to achieve an adhesive form at the tangled interlaced contact point between the two fibers, and it is preferable that the coating amount is at least 0.5 g / cm ² or less. In the present invention, the use of the adhesive adhesive is not the coating treatment of the short microfibers sprayed by the carrier air on the adhesive layer coated on the peripheral surface of the main spindle fiber, but the fine short fibers are stuck into the coating adhesive layer and bonded. The amount of adhesive applied was as small as possible, and we wanted to cure in a short time. For this reason, the water-based adhesive has a composition in which a curing accelerator is blended in the emulsion, and the action of promoting the hot air treatment curing with the adhesive water-based adhesive works so that the amount of water-based adhesive used can be gradually reduced. The composition of the water-based adhesive is obtained by blending a curing accelerator.
Further, the present invention has a problem of improving bulkiness, and the same or different kinds of fiber materials to be subjected to a pre-processing for a desired crimping process in advance for cellulose fibers that are main shaft fibers include cotton, hemp, Fibers such as rayon, polyester, polyamide, vinylon, protein, wool, acrylic, vinyl chloride, urethane, polyethylene, polyolefin, aramid, and polyacrylonitrile can be used. Further, as special fibers, synthetic fibers or fibers containing rayon and vinylon containing photocatalytic titanium dioxide, apatite-coated titanium dioxide, and inorganic ceramic-containing titanium dioxide can be used. Most preferably, a synthetic fiber selected from any of polyester, polyamide, acrylic, vinyl chloride, polyolefin, aramid, urethane, polyacrylonitrile and the like has higher rigidity and is beneficial for improving bulkiness.
FIG. 3 is an explanatory view of a main part in the production process of the fiber-crossing complex of the present invention. After mixing the main spindle fiber 2 and the short microfiber 3, the rare element mineral powder 5 is added, The process of the fiber crossing structure 1a in which any one of the substances is not pressed and held, and the fiber crossing structure 1b which is pressed and held by any one of the third substances through the addition of the rare element mineral powder 5 In the fiber crossing structures 1a and 1b in the lower column of FIG. 3 showing the order, 4 is a third substance, 5 is a rare element mineral granular material, 6 is a gap, and 7 is a crossing contact.

Hereinafter, an embodiment of the present invention will be described.

(1) In the present invention, the principal axis fiber is not a category of synthetic fiber but a cellulosic fiber (viscose rayon) of a plant fiber material that is gentle to the skin, as shown in the manufacturing process flowchart of FIG. in the first step, material feed stock, cut cut, sorted, sieved, dyeing, distributed processing and subjected to adhesive treatment dehydration, allogeneic cell Rurozu fibers of fine short fibers 3 cut milling blended with the spindle fibers 2 The composition of a pseudo hair thickener composition comprising a mixture of the following: cellulose fiber (viscose rayon, manufactured by Ohmi Kenshi), fiber diameter 15 denier × fiber length 0.8 mm as fiber main axis 2, and similar fiber cellulose fiber 0 of sorting and blending at crimped of the cellulosic fibers, the fiber length of the cellulose fibers of the crimp of 8% of the径同length in the vertical axis direction, a 60% reduction 48 mm, cut and pulverized short fibers were used, and even in the blending ratio, the short fibers 3 were mixed so as to contain at least 20% by weight, dispersed, and then subjected to hot air treatment as shown in FIG. By selecting and blending cellulose fibers , a pseudo hair thickener composition can be obtained. However, in the present invention, after passing through the above-described dispersion processing, a process order that shifts to a process that leads to a preceding process in the second process shown in the manufacturing process flowchart of FIG. It has become. In the preceding stage, after pre-air treatment (stirring / dispersing), dry heat shrinkage treatment is performed, followed by spray bonding treatment of the third substance, then hot air drying (adhesion hardening), product inspection / shipment steps However, in order to improve the bulkiness, it is necessary to perform dry heat shrinkage treatment. Therefore, in the first process, the stage before product inspection / shipment, that is, in the first process, selection / fiber The next is the order of the steps directly connected to the previous stage of the second step. That is, in the present invention, from the problem of improvement in bulkiness and improvement, the cellulose fiber is selected and blended through the dispersion process in the normal first step, and directly in the middle without following the production step. The process transition directly connected to the pre-treatment of the next second step is performed, and the pre-stage of the second step is related to the bulkiness which is a problem to be solved by the present invention, and the distortion caused by crimping is fixed between the fibers. A dry heat shrinkage treatment was performed which acts to disturb the parallelism of the film and to improve the bulkiness.
(2) In the second step, an airflow dryer ACD (manufactured by Kumeta Co., Ltd.) 8 is used, and in the pre-stage treatment, after the preliminary wind treatment (stirring / dispersing), the main spindle fiber 2 and the minuteness for bulkiness Each of the short fibers 3 is dry-heated and air-dried, and in the subsequent stage, the mixed and tangled interlaced contact points 7 of the main spindle fibers 2 and the minute short fibers 3 are bonded and fixed. The order of the shipping process.
(3) An acrylic ester copolymer resin emulsion as a water-based adhesive based on a water-soluble resin is used in the adhering treatment of the mixed entangled and crossed contact point 7 of the main spindle fiber 2 and the micro short fiber 3 in the subsequent stage. A three-dimensional structure formed from an entangled chord by mixing with the main spindle fiber 2 to achieve the object by using a small amount of adhesive necessary to achieve the adhesion treatment at the cross contact 7 In the fiber crossing structure 1a or 1b, the bonding and fixing of each fiber at the crossing contact point 7 fixes the distortion caused by the crimping of both fibers and disturbs the parallelism between the fibers. In the fiber crossing structure 1a or 1b, the push-in holding of the third substance is still further, and the center distance between the main shaft fibers 2 and the main shaft fibers 2 is increased. Is not its intersection Adhesive fixing of 7 is the role of the framework of the building assembly, this can be achieved in than the adhesive fixing of crossing contact 7. Therefore, there is no further adhesive fixing of the cross contact 7 in the present invention, and the use of the adhesive there obstructs the space for ventilation in the fiber cross structure 1a or 1b, for example. As a result, the structure may become a factor of covering, which is not preferable.
(4) In the present invention, the amount of the adhesive adhesive used for coating the peripheral surface of the main fiber 2 by hot air treatment is such that the short fiber 3 is coated on the peripheral surface of the main fiber 2 by hot air conveying air. agent layer to sufficient if the form of the adhesive fixed slanted pierced is achieved, solids 5~8g / m ² or less, preferably a small amount of coating amount of 3 to 5 g / m ² or less. Further, the use of the adhesive adhesive in Example 1 is not the coating treatment of the micro short fibers 3 that are sprayed by the carrier air on the adhesive layer coated on the peripheral surface of the main spindle fibers 2, but the micro short fibers 3 are coated therewith. It suffices that the adhesive layer is pierced in a substantially inclined shape and entangled with each other, and the amount of application of the adhesive is as small as possible, and curing in a short time is desirable. For this reason, the water-based adhesive of Example 1 has a constitution in which a curing accelerator is previously blended in the emulsion, and the action of promoting the hot-air treatment curing with the adhesive water-based adhesive is the amount of water-based adhesive used. The composition containing the acrylic resin emaldin as the main component is as follows.
・ 100 parts of self-crosslinking acrylic resin emulsion (trade name Rikabond ET-111 Chuo Rika Kogyo)
・ Melamine resin 1-5 parts (Brand name UNIKA RESIN 380K Union Chemical Industries)
・ Curing accelerator 0,4-0.8 parts (Brand name UNIKA CATALYST A-35)
・ Tackifier 5-10 parts (Boncoat, W-26 Dainippon Ink)
・ Ammonia water appropriate amount catalyst 0.2-1.0 parts (trade name UNIKA, CATALYST A-35)
In the configuration in which the main fiber 2 is entangled with the main fiber 2 by bonding at the crossing portion 7 with the minute short fiber 3, first, the main fiber 2 in which a coating layer is applied to the peripheral surface of the main fiber 2 is a hopper. The main shaft is supplied and supplied from a10, and is provided with a time difference by the conveying air under the heating condition in the drying tube 17, and the micro short fibers 3 are sprayed with the spraying air to coat the peripheral surface to which the adhesive is applied with a sticky adhesive. An interlaced contact 7 in an entangled shape and / or a cross-linked shape at a substantially inclined angle is bonded and fixed to the fiber 2 to form a fiber interlaced structure in the form of an entangled chord composed of a mixture of the main fiber 2 and the minute short fiber 3 Body 1a was constructed. Thus, the use of the adhesive in the present invention is not a type such as dipping or coating, but is a partial adhesive fixing of the cross contact 7 in a mixed entanglement of both fibers, and a small amount of adhesive water-based adhesive is used. In addition, if it is a small amount, spraying with spraying air is expected to accelerate the curing of the aqueous adhesive, and the composition of the curing accelerator is set after curing the spraying process of the micro short fibers 3 with spraying air. Has the effect of working to speed up.
(5) The bulkiness in Example 1 is such that, in the case of only the first step, the rayon main shaft fiber 2 has a shrinkage of 8%, a fiber length of 60%, and a blending ratio of 20%. 0.8 cm ³ . That is, in terms of its bulkiness, the bulkiness consisting only of the mixing of the main spindle fibers 2 and the microshort fibers 3 in the first step is different from the dryness due to the use of residual shrinkage of each fiber in the dry heat shrinkage treatment in the second step. By heat shrinking and bonding and fixing of the cross contact 7 of the fiber cross structure 1a, the bulkiness was 6.5 cm ^3, and a result that could be improved was obtained.
(6) Further, in Example 1, (1) natural mineral containing rare elements, far-infrared emitting material 10 mu tourmaline powder 50:50, (2) photocatalytic titanium dioxide 50 added and blended A hair thickener composition was obtained. As a result, the release of negative ions in minerals containing rare elements and the antibacterial / deodorant effect of far-infrared radiation further exerts the antibacterial / deodorant excitation action by a photocatalytic functional material such as photocatalytic titanium dioxide. .
3 wt% of the above fiber cross structure 1a was mixed with powder to obtain a pseudo hair material. As a result, in addition to the effect of imparting antibacterial and deodorant properties, the structure for obtaining a three-dimensional three-dimensional structure in the present invention is also in another aspect, a plurality of pseudo hair base materials having rayon fibers as main axes communicate with each other. The presence of the space portion can exert its effect in terms of action even in the emission of negative ions of minerals containing rare elements and the emission of far infrared rays. As mentioned above, rare minerals include inorganic mineral powders and far-infrared radiation materials, both inorganic fine particles, giving heavy hair to damaged hair and finely adjusting luster. Work as you can.
(7) Next, for antibacterial and deodorant imparting in the present invention, a natural mineral (minus ion emitting substance) 10 mu monazite powder containing rare elements and far-infrared radiation are added to the fiber-crossing structure 1a. Using a mixture of the substance 10 mu tourmaline powder 50; 50, (2) the 10 mu monazite powder and the far infrared radiation substance serajit AL-F9 50: 50, the fiber crossing A pseudo hair material was obtained by mixing 3% by weight of powder with respect to the structure 1a. As a result, in addition to the effect of imparting antibacterial and deodorant properties, the configuration for obtaining the three-dimensional structure of the fiber according to the present invention is also communicated between the pseudo hair base materials mainly composed of rayon fibers in another aspect. A plurality of voids 6 are provided, and the presence of the voids 6 in the release of negative ions of minerals containing rare elements and the far-infrared radiation is such that the inner space and outer sheath of the fiber interlaced structure 1a are fine. Since it communicates with the slit, the effect can also be exhibited in terms of water absorption. In addition, as mentioned above, natural minerals containing rare elements are inorganic fine particles, both inorganic mineral powders and far-infrared emitting materials, giving a heavy texture to the hair in the damaged thin hair portion and giving a finer gloss. In addition to being able to adjust, it works to make it look closer to natural hair even when it is glossy under direct sunlight.

(1) The main shaft fiber 2 in the first step is a cellulose fiber (viscose rayon, cellulose fiber (viscose rayon, manufactured by Ohmi Kenshi)), fiber diameter 7 denier × fiber length, as in Example 1. The main fiber length is 0.5mm, and the fiber length is perpendicular to the same length and same diameter polyamide fiber with a crimp rate of 11.5% by pre-crimping the polyamide fiber from the selection and blending of the cellulose fiber and dissimilar fiber polyamide. In the axial direction, 60% cut 0.3 short fibers cut and pulverized were used and mixed such that the short fibers contained at least 20% by weight even in the blending ratio. of as shown in the manufacturing process flow chart, the problem to be solved with the increase in bulkiness and improved, not follow the product step than the formulation of sorting and heterologous fiber polyamide through distributed processing in a normal first step, the middle, Next, the process transition directly connected to the pre-treatment of the next second step is performed, and crimping related to the bulkiness is applied, which works to improve the bulkiness which acts to fix the distortion and disturb the parallelism between the fibers. Dry heat shrinkage treatment was performed.
(2) Next, in Example 2, in order to further increase the bulkiness, the fiber crossing structure 1b formed by bonding and fixing at the tangled crossing contact point 7 between the main shaft fiber 2 and the minute short fiber 3 In Example 2, it is the structure which pushes in and hold | maintains fine animal hair as a 3rd substance which pushes in and hold | maintains to the space | gap 6 in Example 2 similarly to Example 1, and the average major axis is 30 micrometers. The following is preferable, and the blending amount is preferably in the range of 0.1 to 20% by weight. Furthermore, in the blending, components usually used in hair cosmetics such as a surfactant, a humectant, an ultraviolet absorber, and a thickener can be blended as appropriate. The fine animal hair as the third substance in Example 2 is preferably dyed after the classification treatment, but the dyeing is well harmonized with human hair, excellent in gloss and fastness, Is selected from those containing a dye composition suitable for concealment in the thin hair portion, but in the dyeing of the third substance in Example 2, it is preferable to use a chrome-containing acidic dye, and especially the color and gloss of human hair It works to function as a component of the pseudo hair material that is not particularly likely to cause brown or color transfer similar to. Examples of chromium-containing acid dyes are shown below.

・ Kayakaran Yellow GL143 (Yellow dye)
・ Kayakaran Red BL (Red dye)
・ Kayakaran Gray BL167 (Blue dye)
・ Kayakaran Brown GL (Brown dye)
・ Kayakaran Black BGL (Black dye)
The dyeing is performed such that the dye is 0.01 to 45 parts by weight, preferably 1 to 40 parts by weight, per 100 parts by weight of fine animal hair powder. When the blending ratio of the dye is less than 0.01 parts by weight, the degree of dyeing tends to be insufficient, and when it exceeds 45 parts by weight, the dyeing is sufficiently performed, but excess dye remains in the reaction bath. Manufacturing cost increases.
(3) Next, in the second step, as in the first embodiment, the airflow dryer (made by Kumeta Co., Ltd., ACD type) 8 is used in the first step, and first, hot air drying (non-adhesive treatment) is performed. After drying (partial adhesion treatment), in the same manner as in Example 1, the main spindle fiber 1 coated with the adhesive adhesive on the peripheral surface is supplied and supplied from the hopper a10, and the short short fiber 2 is supplied from the hopper b11 after a lapse of time. It is sprayed in a substantially inclined shape with spraying air, and an entangled fiber crossing structure 1b is formed by bonding and fixing at the crossing contact point 7 with the main fiber 1. As the adhesive adhesive, an adhesive based on a self-crosslinking acrylic resin emulsion was used as in Example 1. As a result, when the simulated hair thickener is sprayed or sprinkled on the hair defect or thinning portion, a three-dimensional structure with the main fiber 1 as the pseudo hair substrate is formed, and the bulky volume feeling can be improved. , Has a concealment effect. In addition, a plurality of voids 6 communicating with each other between the artificial hair bases of the fiber main shaft are provided, and the presence of the voids 6 is also effective in the emission of negative ions from minerals containing rare elements and the emission of far infrared rays. The effect can be demonstrated. Thus, as the third substance of Example 2, animal hair fine powder including human hair is mixed with the main spindle fiber 1 and the minute short fiber 2 in the first step, and dry heat shrinkage with hot air in the second step. After the treatment, the animal hair fine powder is pushed into the gap 6 of the fiber crossing structure 1b by an aerosol spraying method or held in any crossing part of the structure 1b, so that the mutual contact with the main fiber 1 Since the center distance between them increases, it is a structure that works to improve the bulkiness. Thereby, in the bulkiness, when it consists only of the mixture of the main spindle fiber 1 and the micro short fiber 2 in the first step, the bulkiness is 5.5 cm ³ , and the dry heat shrinkage treatment in the previous stage of the second step. As a result, the bulkiness can be improved to 6.3 cm ³ by bonding and fixing the cross contact at the latter stage.

(1) As in Example 1, the main spindle fiber 1 in the first step is a cellulose fiber (viscose rayon, cellulose fiber (viscose rayon, manufactured by Ohmi Kenshi)), fiber diameter 3 denier × fiber length. 0.5mm is the fiber main axis 1, and the length of the fiber is 0% cut in the vertical axis direction from the polyester fiber of the same length and the same diameter of the polyester fiber crimped from the selection and blending of the predetermined fiber, before the polyester fiber crimping treatment. .4 mm, cut and pulverized short fibers were mixed so that the blend ratio of the short fibers 2 was at least 20% by weight, and as in Example 1, as shown in the manufacturing process flowchart of FIG. Due to the problem of improvement in bulkiness and improvement, it is directly connected to the first stage of the next second process in the middle without going through the process of productizing from the combination of the selected fiber and the selection / dispersion through the usual dispersion process in the first process. Process change Was carried out, with crimping according to the bulkiness, the distortion were fixed and subjected to dry heat shrinking treatment acting on improvement of bulkiness acting disturbing parallelism between the fibers each other.
(2) Next, in the second step, similarly to Example 1, in the preceding stage, first, hot air drying (non-adhesive treatment) was performed using an airflow dryer (Kumeta Seisakusho, ACD type) 8, and then hot air After drying (partial adhesion treatment), the spindle fiber 1 coated with a sticky adhesive on the peripheral surface is supplied and supplied from the hopper a10, and the minute short fibers 2 are substantially inclined with the spreading air from the hopper b11 with a lag time difference. By spraying and bonding and fixing the intersection contact 7 with the main shaft fiber 1, the structure of the fiber intersection structure 1 b having a chordal three-dimensional structure is obtained. As the adhesive adhesive, an adhesive based on a self-crosslinking acrylic resin emulsion was used as in Example 1.
(3) Next, also in Example 3, in order to further improve the bulkiness, it is pushed into the gap 6 in the fiber interlaced structure 1b formed by the mixed entanglement interlace of the main spindle fiber 1 and the minute short fiber 2 or In the holding, Example 3 is a structure in which urethane powder is held as the third substance, and the fine powder having an average major axis of 30 μm or less is preferable, and the blending amount thereof is 0.1 to 20% by weight. A range is preferred. Furthermore, in the blending, the components used in normal hair cosmetics such as surfactants, moisturizers, ultraviolet absorbers, thickeners and the like can be blended as appropriate into the components of the urethane powder fine powder. As described above, as the third substance in Example 3, urethane powder fine powder is first mixed with the main fiber 1 and the short short fiber 2 in the first step, and dry heat shrinkage treatment with hot air in the second step. After that, the center distance between the main fiber 1 and the spindle fiber 1 is increased by being pushed into the gap 6 of the fiber crossing structure 1b or being held in the structure 1b by the aerosol spraying method, and the dry heat shrinkage treatment in the previous stage Thus, it has a configuration that works to improve the bulkiness in addition to the effect that the bulkiness can be obtained by fixing the strain and disturbing the parallelism between the fibers. Thereby, in the bulkiness, when it consists only of the mixture of the main spindle fiber 1 and the micro short fiber 2 in the first step, the dry heat shrinkage in the previous stage in the second step, compared with the bulkiness of 5.2 cm ^3. In addition, the bulkiness was improved to 5.9 cm ³ by bonding and fixing the cross contact 7 in the latter stage, and a result that could be improved was obtained.

(1) As in Example 1, the main spindle fiber 1 in the first step is a cellulose fiber (viscose rayon, cellulose fiber (viscose rayon, manufactured by Ohmi Kenshi)), fiber diameter 3 denier × fiber length. Using 0.3mm as the main shaft fiber, the fiber length of the polyester fiber of the same length and the same diameter with a crimp rate of 11.5% is obtained by pre-crimping the polyester fiber from the selection and blending of the cellulose fiber and the different fiber polyester. In the vertical axis direction, 80% cut 0.24, cut and pulverized short fibers were used and mixed so that the blend ratio was at least 20% by weight. As shown in the manufacturing process flowchart of FIG. 4, from the problem of improvement in bulkiness and improvement, through the usual dispersion process of the first process, the process of commercialization from the selection and blending of fibers is not followed, directly in the middle. A process transition directly connected to the front stage of the second step of the above, and by applying crimp related to bulkiness, dry heat shrinkage treatment that works to improve bulkiness that works to fix the distortion and disturb the parallelism between fibers went.
(2) Next, in the second step, as in the case of Example 1, in the pretreatment, first, after using an air flow dryer (made by Kumeta Co., Ltd., ACD type) 8, first through hot air drying (non-adhesive treatment), After hot air drying (partial adhesion treatment), as in Example 1, the main spindle fiber 1 coated with a sticky adhesive on the peripheral surface was supplied from the hopper a10, and the micro short fibers 2 were removed from the hopper b11 with a lag time difference. The main fiber 1 and the cross contact 7 were adhered and fixed by spraying air with a sprayed air to form a tangled fiber cross structure 1b. As the adhesive adhesive, an adhesive based on a self-crosslinking acrylic resin emulsion was used as in Example 1.
(3) Next, in Example 4, in order to further improve the bulkiness, the hollow fiber 6 is pressed and held in the gap 6 of the fiber interlaced structure 1b formed by the mixed entanglement interlace of the main spindle fiber 1 and the minute short fiber 2. As the third substance, the microcapsules are held. The average major axis is preferably a fine microcapsule having a size of 30 μm or less, and the blending amount is preferably in the range of 0.1 to 20% by weight. Furthermore, in the blending, the components used in normal hair cosmetics such as surfactants, humectants, ultraviolet absorbers, thickeners and the like can be blended with the fine microcapsule components as appropriate. As described above, as the third substance in Example 4, fine microcapsules are first mixed in the first step with the spindle fiber 1 and the microshort fibers 2, and then in the second step, the dry heat shrinkage treatment with hot air is performed. Later, together with the mixture of the microscopic microcapsules and other components, the mixture is pushed into the gap 6 of the fiber crossing structure 1b by an aerosol spraying method or held in any crossing part of the structure 1b. Since the center distance between the main fiber 1 and the spindle fiber 1 is increased, and the crimping by dry heat shrinkage as described above fixes the strain and disturbs the parallelism between the fibers, the bulkiness of the fiber It is a structure that works to improve. Thereby, in the bulkiness, when it consists only of the mixture of the main spindle fiber 1 and the micro short fiber 2 in the first step, the bulkiness is 4.8 cm ³ , and the remaining in the previous stage in the second step. The bulkiness obtained by dry heat shrinkage due to the use of shrinkage, and the bulkiness was 5.6 cm ³ by the subsequent treatment, and the result that the bulkiness can be improved was obtained.
