BEST MODE FOR CARRYING OUT THE INVENTION The textile for piloerection 1 (hereinafter referred to as piloerection) in the present invention is It is a short fiber made of fiber or synthetic fiber. The length of this short fiber varies depending on the stimulating fiber 1 (a) (hereinafter referred to as stubble) and the downy woven fiber (hereinafter referred to as downy hair). longer than b. However, it is preferred that they be approximately the same length between stabs or between downy hairs.

In the present invention, the stimulating hair 1a and the downy hair 1b are used alone or in combination. In the case of combined use, the irritated hair 1a should be adjusted to the range of 20 to 60% by weight, preferably 30 to 50% by weight, based on the total amount of the piloerection. It is preferred because of its characteristics such as hair flow.

The stab 1a may have some crimps, but straight fibers are preferred. Also, a fiber having crimps is preferred for the downy hair 1b. Here, the term “crimp” refers to a crimp number of 4 to 10 yamano 25, and a crimp frequency of about 3 to 8%. In particular, in the case of downy hair, a finely crimped fiber having a small value among such crimps exhibits preferable characteristics of preventing ground cracking and improving apparent nap density. A straight is a crimp smaller than the above-mentioned crimp and is substantially linear.

Usually, about 20 to 70 d for the stabbing hair 1 a and about 20 to 40 fiber length «about 1 to 7 d for the downy hair 1 b and, if necessary, less than 1 d of ultrafine fibers (0 1 ~ 0.001 d), a fiber length of about 15 ~ 30 ιι is applied. However, in the case of the artificial fur of the present invention, these numerical values can be appropriately changed depending on the type of fur to be designed.

As the material for the raised hair, a natural fiber may be used, but due to the properties of the weave of the raised hair, the ease of processing, and the availability of synthetic fiber, Is preferred. Examples of such synthetic fibers include polyester-based arrowhead fibers, polyamide-based fibers, and polyacrylonitrile-based fiber-based acetate fibers. Among such synthetic fibers, polyester-based fibers and polyamide-based arrowheads are preferred in view of the ease of Taber. In particular, polyester fibers are preferable because they easily form an extremely beautiful tabular shape with a sharp point at the sharp end by an alkali aqueous solution-liquid. Even among polyester fibers, polybutyrench phthalate fibers have long taper lengths. In addition, the fiber made of polybutyrene terephthalate nikon 66 has excellent rebound resilience and is preferable as the nap 1. This textile is particularly useful as sting 1a.

The shape of the fiber constituting the nap 1 is not limited, but a fiber having an irregular cross-sectional shape having a ridge line in the axial direction of the fiber, such as a flat type or a flat cross type, has a limp, elasticity, and luster. It is preferable in terms of properties and the like. Such fibers are particularly useful for hair 1a. The nap 1 is preferably a fiber having at least one end tapered. In particular, in the case of stab 1a, the tapered texture significantly improves the texture and texture.

In order to obtain such tabered fibers, there are a chemical method for dissolving or decomposing the fiber, a physical method such as stretching and cutting the fiber, and a method such as a combination of these methods. The one obtained by the chemical method makes it easier to obtain desirable textile properties. For example, in the case of a polyester-type arrowhead fiber, it is easily decomposed into 5 テー water using an aqueous alkaline solution to form tabers. For example, a method described in JP-A-54-38922 and JP-B-50-40915 can be applied.

The nap structure 2 (hereinafter referred to as a ridge) according to the present invention refers to a band 8 of the nap 1 having a certain width that is continuous in the length direction and formed by implanting the nap 1 through the base cloth 3 and implanting the nap. Say.

Here, the ridges 2 formed by implanting the nap 1 through the base cloth 3 and being implanted are mainly a nap structure that is implanted by the needle bunching method. It may be held inside. The width X of the band 8 is arbitrary, but is preferably 20 cm or less in view of the surface characteristics (surface change) caused by the piloerection 1. In particular, when the distance is 3 to 15 cm, the characteristics are remarkably exhibited.

The ridges 2 may be used alone (one unit) or in a form in which a plurality of ridge units are surrounded or discontinuously assembled. However, in the case of artificial fur in which one ridge unit or a plurality of ridge units are assembled in a non-continuous manner, it may be necessary to forcibly sew the portion where no nap is present during sewing.

The nap 1 constituting the ridge 2 has a longer nap 1 at the center and a shorter nap 1 at the end of the ridge 2 than the nap 2 having the same length in the width direction X. Is more preferable because the tilted standing hair 1 of the present invention can be easily obtained. In particular, it is preferable that the shape be gradually shorter (crest-shaped) from the center to the end. In this case, a structure in which the length of the nap 1 at the center is about 10 to 40% longer than the end is preferable for achieving the hair flow characteristics of the present invention. This property is also exhibited when the density of the nap 1 at the center is higher than that at the end. Flocking density is about 20-50% more than at the end The above purpose can be preferably achieved when the central part is higher. The piloerection length and the flocking density exert a synergistic effect, and a configuration in which these are combined provides a preferable result in the present invention.

Here, the central part means the middle part of the erected 8 divided into three equal parts if the erected hair 1 has the same length in the width direction X of the erected structure. In some cases, it means the peak, and when the density is different, it means the high density part.When the nap length and the density are synergistic, the effect of either one of the requirements on the nap flow is considered. It can be determined by the person with the higher specific gravity. However, in the usual case, it may be considered to mean the middle part divided into three.

The feature of the artificial fur of the present invention is that the entire nap 1 is inclined in the longitudinal direction Y of the band 8 as shown in FIG. This tilting significantly improves the glossiness of the standing hair 1. A preferable inclination angle is about 40 to 70 degrees with respect to the base cloth 3. If you lean more than 70 degrees, the tendency to get more tangled tends to increase. When it comes upright from 40 degrees, the concealing effect of the base fabric 3 and the downy hair 1b is reduced, and the touch and the gloss tend to be inferior. The feature of this is that, as shown in Fig. 3, in addition to the entire inclination of the nap 1 as described above, when the nap 1 is viewed from above, the flow of the nap is the band 8 at the center in the width direction X of the nap. It is parallel to the longitudinal direction Y, on both sides it gradually opens outward to the longitudinal direction Y of the belt 8, and at the outermost side it is at an angle of 10 to 80 degrees, preferably 20 to 70 degrees Flowing outwards, Such three-dimensional three-dimensional napping characteristics are features not found in conventional artificial fur. This feature can be seen in Fig. 5 both in the artificial fur formed in one ridge unit as shown in Fig. 2 and in the artificial fur formed in the form of a set of many ridge units as in Fig. 4. And so on. FIGS. 13 and 14 show photographs of one embodiment of the artificial fur of the present invention corresponding to the model diagrams shown in FIGS. 3 and 4, respectively, for reference. The part of the photograph that is partially black is the part of the shadow caused by the projected light generated by the artificial fur arrangement method at the time of photographing.

Here, the ridge parallel to the longitudinal direction Y does not need to be completely at 0 degrees with respect to the longitudinal direction Y. Even if there is a slight change, as long as the nap 1 is facing the longitudinal direction Y as a whole, It is meant that the object of the invention is achieved. Of course, closer to 0 degrees produces a more pronounced effect. In addition, the nap 1 on both sides of the nap 1 gradually changes outward from the center in the width direction X of the nap structure from the center to the end. It does not need to flow to the above angle as soon as it comes off. However, the above angles must be satisfied at both ends. If the angle of the hair flow at the end is less than 10 degrees, the dry pattern is hard to appear, and if it exceeds 80 degrees, the interference becomes too strong, causing disturbances in the dry pattern, resulting in esthetic and external appearance. Not preferred from above.

For the first time after achieving such napping properties, the nappings 1 facing outward between the ridges 2 collide and interfere with each other, and a single interference between the ridges 2 and 2 shown in Fig. 5 The effect that a pattern appears can be exerted. In general, high-grade fur made of animal hair such as mink goes through a retorting process, where one fur is first cut into small pieces and rearranged. A phenomenon occurs in which the napped structure tilts uniformly and parallel. The result is that even fine fur coats such as mink have poor interference patterns and poor aesthetic surface changes.

The artificial fur of the present invention is extremely excellent in terms of the interference pattern and the aesthetic surface-modifying property of the nap 1, and exhibits the same performance as that of mink or fox. Another factor that promotes the nap is a nap structure in which a plurality of naps 1 penetrate the base fabric 3 in a bundle. That is, the nap 1 of the present invention has a structure in which the nap 1 is planted by a needle bunching method, but all the naps 1 are planted in a bundle of a plurality of bundles by one-side punching. This napped structure is characteristic of the present invention. In the artificial fur of the present invention, a plurality of raised hairs 1 exist at one flocking point (hole) regardless of the irritated hair 1a and the downy hair 1b. This structure works effectively in achieving the above-described piloerection properties despite being artificial fur. Furthermore, this structure has the effect of preventing the nap 1 from coming off and significantly improving the recovery property by stroking the nap 1.In the subsequent treatment with the liquid, the nap structure 1 can be safely provided until the treatment effect is achieved. This has the effect.

Here, the reversible stroke is the first (original) tilt when the hand is stroked by hand in the opposite direction to the tilting direction of the piloerection 1. If the property is poor, the napped form is not stable, is easily disturbed, and the quality of the napped 1 when worn is remarkably lacking.

In the present invention, structural factors such as independence of each napped bundle (flocked point) and random distribution thereof also have the effect of promoting the napped characteristics. The structure is capable of sufficiently unwinding the restraint at the time of hair transplantation at the time of the subsequent liquid flow treatment, and also works effectively in forming the hair flow, and the random distribution of the latter It has the effect of preventing uniform distribution and counteracting artificial feeling.

In order to complete the napped characteristics, the present invention is also characterized in that a polymer elastic film 4 is provided on at least one surface of the base cloth 3 as shown in FIGS. The coating 4 significantly improves hair transplant density, improves artificial fur strength, and prevents hair loss. It is preferable to provide the coating 4 not only on one side but also on both sides, since the effect of the improvement is further increased. The coating 4 may penetrate not only to the surface of the base fabric 3 but also to the inside of the base fabric 3, and the coatings 4 on the front and back surfaces may be partially integrated inside the base 3.

It should be noted that, in the present invention, the film 4 does not need to be present separately from the film, but means that the polymer elastic film 4 is distributed on the surface of the base fabric 3. However, it is obvious that such a film 4 having the film 4 on the surface of the base cloth 3 is superior in properties such as the gripping force of the nap 1 and the strength of the base cloth 3.

The thickness of the coating 4 is at least 1, preferably 5 to 50. μ, and particularly preferably in the range of 10 to 30 <«, to prevent the base cloth 3 from breaking down due to bunching, further greatly improve the morphological stability of the base cloth 3, and have a high flocking density It has the effect of being able to withstand the same. If the film thickness is too thin, the above effects will not be sufficiently exhibited, and if it is too thick, the hand will harden.

Furthermore, this coating 4 is also characterized in that it has properties suitable for bunching flocking. In other words, when the needle 6 penetrates, the hole (pore) formed by the needle 6 is extended by its elasticity, and contracts after punching. This action exerts an action of suitably gripping the planted nap 1, and the properties of the polymer elastic body coating 4 and the strength of the base fabric 3 are simultaneously improved. And the thickness of the base cloth 3 was reduced to a thickness as close as possible. This effect greatly affects the flexibility of the artificial fur of the present invention. For example, in the case of non-woven fabric, the limit of punching flocking is at most about ZO Og Z m ', and even if the hair is forcibly implanted without considering the feeling and appearance, the base fabric breaks at 300 g / m'. However, according to the present invention, it is possible to increase the flocking density to 500 g π 'or more, and further 700 g nom or more. Even at the thickness of the base cloth 3, it is possible to form an artificial fur with a thickness of 50 g / nf in the limit.

Examples of the polymer elastic body for the coating 4 include elastomers such as urethane-based resin, acrylic-based resin, silicone-based resin, and fluorine-based resin. Above all, a polyurethane resin is excellent in elasticity and is suitable for the present invention. Examples of such polyurethane resins include various polyether polyurethanes, polyester polyurethanes, and polyester polyether polyurethanes. Such resins are obtained by reaction with long-chain diols (polyesters or polyethers), diisocyanates, and low molecular weight chain extenders (glycols, diamines, etc.).

The base fabric 3 supporting the nap 1 of the present invention can be applied to a woven or knitted fabric, a nonwoven fabric, or a combination of these fabrics. In particular, the non-woven fabric is selected from the viewpoints of texture, ease of control of the appearance, ease of punching, and durability against punching. A fine denier is preferred in terms of flexibility, for example, an ultrafine fiber of 1 d or less, and more preferably 0.1 d or less. Such a fiber can be easily formed from a composite fiber such as a sea-island fiber or a detachable fiber by removing or separating the sea. In the case of sea-island-type textiles, it is preferable that the sea component is composed of polystyrene and the island component is composed of polyester. The basis weight of the base fabric 3 is about 50 to 250 g Z rrf, but it is flexible and lightweight. It is preferable from the viewpoints of texture and hand. If the basis weight is less than 50 g / m ', the strong meaning of the base cloth 3 cannot be said to be sufficient, and 250 ₈ ! Beyond ^, the texture tends to be hard.

Thus, the artificial fur of the present invention has features that are not found in conventional artificial fur, such as having a distinctive appearance, feeling, and excellent surface changes due to three-dimensional three-dimensional raised hair properties. The high quality image is outstanding.

Next, a method for producing the artificial fur of the present invention will be described. In the artificial fur of the present invention, the use of a non-woven fabric as the base fabric 3 provides a suitable result. Hereinafter, the case of using the non-woven fabric as the base fabric 3 will be described.

The nonwoven fabric can be produced by a usual method, for example, a method such as a spunbond method, a needle punching method, or a water punching method. The fibers and weight used are adjusted in consideration of the conditions and ranges described above.

A film 4 of the above-mentioned elastic polymer is formed on the nonwoven fabric 3 thus obtained. As a forming method, a method such as a direct coating method or a transfer method, a polymer elastic film lithography method, and a dipping method can be applied.

In general, a method of applying a solution of a polymer elastic material onto the base fabric 3 is simple, and is preferable in terms of an adhesive effect by permeation into the base fabric 3 and the like. For example, in the case of a polyurethane-based resin, a solution obtained by dissolving polyethylene in a solvent such as dimethylformamide methylethylketone (mixed solvent) at about 10 to 30% by weight is used. The viscosity of this solution is preferably about 5,000 to 15,000 cp because the formability of the coating 4 is excellent. In the case of the impregnation method, it is required that the polyurethane is migrated to the surface of the base fabric 3 so that the polyurethane is unevenly distributed on the surface. Usually, when soaked and dried, polyurethane migrates to the surface and its concentration on the surface increases, and the tendency is more pronounced at higher temperatures. it can.

This is a new process that has not been attempted in the conventional artificial fur manufacturing process. Such a coating 4 can be formed on one or both sides of the base fabric 3.

Next, the nap 1 is formed on the base cloth 3.

The nap 1 is implanted by the needle bunching method, but the nap is achieved by depositing the nap 1 to be implanted on the base cloth 3 and then performing the nap with the needle 6 from above. Depending on the kind of needle board 5 used at this time, one or more (8 as many as desired) strips 8 can be obtained. For example, in the case of FIG. 9, one band 8 of the napped structure is obtained, and in the case of FIG. 10, bands 8 as many as the number of needle groups in the figure are obtained. In each case, the piled nap 1 where there is no needle 6 is not planted, so it is completely eliminated in the subsequent process. The depth of the needle 6 of the needle 5 can change the length of the obtained nap 1, and the density of the needle 6 can change the density of the nap. However, the flocking density can also be adjusted by increasing or decreasing the amount of the nap 1 deposited on the base fabric 3, and usually the density of the bristle is adjusted by this method from the viewpoint of the characteristics of the base fabric. I do. For example, if it is desired to increase the planting density at the center of the band in the width direction X, it is sufficient to deposit a considerable amount of nap 1 at that location.If you want the nap to be longer at the center than at the ends, for example, As shown in Fig. 11, the needle depth at the corresponding location may be set shorter than the end. Such an action mechanism can also be achieved by changing the shape of the base cloth 3. For example, the base cloth 3 is fixed to a curved and concave bed board (not shown), and a board 5 having a horizontal needle 6 at the same depth is used. The same effect as above can be obtained by punching.

As described above, according to the present invention, even in the case of artificial fur having a large number of bands 8, the valleys 9 are raised by adjusting the needle depths of the bands 8 and the valleys 9 of the bands 8. It is easy to design such as whether to finish without 1 or to leave fine nap 1. In this case, it is also effective depending on the design to adjust the type and pile amount of the nap 1 at the location corresponding to the valley 9. Therefore, for example, by adjusting the distance of the valley portion 9 and the length of the nap forming the band 8, the entire base cloth 3 has a large number of bands 8 of the nap 1 having a dried pattern, and A wide artificial fur having short downy hairs 1 b densely in section 9 can be easily and at once manufactured.

The needle punching of the present invention may be performed in a plurality of times, if necessary. For example, in the case of artificial fur having a large number of bands 8, the first bunching is performed using a material having no needle 6 in a portion corresponding to the valley of the needle board 5, and then performing By performing the second punching with the board 5 having the needle 6 on the entire surface of the needle board 5, the efficiency of flocking can be improved.

As the needle 6 used for the needle bunching, a normal needle can be used, but as shown in Fig. 12, the height of the gauge and the kick-up 7a, the angle 7b and the length of the throat 7 By selecting and using different shapes of barbs 丄 such as c and depth ならびに d and a different number 6 at the center and the end in the width direction X of the napped structure, the bristles are formed at the center 1 a Down hair more than 1 b The hair can be planted. For example, the use of a needle 6 with a shallow throat depth of 7d and a short kick-up at the end facilitates the selective implantation of fine textiles, and therefore the downy hair at the end

You can implant 1 b more than 1 a.

Fig. 12 shows an example of a kick-up type barb JL. In this way, the barb that is deeply recessed and whose tip protrudes from the side line is easier to plant thicker denier naps, 1 If a barb with the same upper end as the side line and a shallower shape is used, thin denier naps can be easily implanted. Such effects are further multiplied by the gage.

The napped structure thus obtained is, if necessary, temporarily fixed with a water-soluble glue such as Bolibul alcohol. However, the present invention does not require this step, and has the advantage that this step can be eliminated.

The napped structure then forces the flocked fibers protruding from the back surface of the base cloth 3. If necessary, the above-mentioned elastic polymer solution is applied to the back surface after the shaving treatment, and further fixed. Next, the nap structure thus treated is subjected to a nap treatment with a normal needle cloth or the like, so that the nap 1 is raised.

In the case where the sea-island-shaped fiber or the detachable fiber is used for the base fabric 3, the base fabric 3 is subjected to a softening treatment after the raising treatment. The softening process is a process in which the base fabric 3 is deniered and softened by removing or separating from the sea. For example, if the base fabric is composed of a composite fabric consisting of polystyrene for the sea component and polyester for the island component, the tri-crease is usually used as a solvent. Desea with halogenated hydrocarbons and hydrogen.

Next, the nap structure is passed through a nap structure together with a liquid through a device as shown in FIG. 8 to provide hair flow characteristics, which is one object of the present invention.

This process is also a new process not included in the conventional artificial fur manufacturing process.

In this step, a long textile product such as a fabric is transported together with the liquid in a liquid, and the liquid is processed while giving a physical action while traveling. In this process, the piloerection structure is transported and traveled in one direction, and the piloerection 1 is restrained by the physical action received during the travel, and a favorable hair flow is given. This effect tends to be more pronounced for narrow objects than for wide objects. In this process, not only the above-mentioned restraining action but also a kneading action and a relaxing action are simultaneously applied to the workpiece. Therefore, there is also an effect that the object to be treated is further softened here.

Such a physical action is given in the space, and this space has a slit-shaped or nozzle-shaped mechanism 14 as shown in FIG. 8 (). In the form of a spread, the latter in the form of a rope, it passes through the mechanism 14.

In any of the mechanisms 14, the cross-sectional area in the width direction X with the nap of the nap structure, which is the object to be treated (the cross-sectional area measured when a load of 1 g erf is applied to the nap 1 surface) Area) is the cross-sectional area of the mechanism 14

(Slit or nozzle space area) should be set to 5 to 60%. Of course, adjust the mechanism 14 so that the above relationship is satisfied. Is also good. If the above relationship is not satisfied, the base fabric 3 becomes difficult to pass, and the hair flow effect becomes insufficient.

By setting such a space, the object to be processed passes through the space together with the liquid under a certain restriction. In this case, the piloerection structure is strongly restrained in the space, but this restrained state exerts a clever action of tilting the piloerection 1 in one direction and inclining outwardly in portions other than the center. Is what you do. The liquid referred to in the present invention is usually a liquid mainly composed of water. However, when a solvent treatment is necessary, an organic solvent may be used. For example, dyeing or resin processing can be performed at the same time as providing hair flow properties. Dyeing is achieved by using a dye composition liquid as the liquid, and resin processing is achieved by using the resin composition liquid as the liquid.

The use of a high-speed liquid as such a liquid further enhances the above-described effects, and is therefore suitable for the present invention. Such a high-speed liquid means a jet liquid flow, and a liquid flow to be jetted in a range of preferably about 50 m / sec to 300 m / sec is selected.

As such a processing device 10, for example, a device called a liquid flow processor can be applied. Specific examples include "Jet 'Dying' Machine" (Gaston Co., Ltd.), "Zaculer (Osaka Manufacturing Co., Ltd.)", "Dashline" (Oshima Machinery Co., Ltd.) Liquid flow dyeing machines such as "Masflow" (manufactured by Takata Seisakusho).

In such an apparatus 10, an object to be processed is previously passed around the transfer path of the apparatus 10, and its both ends are connected to form a loop. Must be shaped. The object to be processed in a loop is pulled by the jet jet flow, sequentially transferred in the transfer path, returned, and subjected to the constraint processing.
