Abstract

[PROBLEMS] For a natural fiber, a tourmaline-containing fiber product has to be produced by bonding tourmaline fine particles to a fiber surface with a resin or the like. It has been demanded that the functional properties of tourmaline be imparted to the silk fibers while maintaining the original functional properties of the silk fibers.

After the silk fiber product is saturated with the aqueous suspension containing the tourmaline fine particles, the silk fiber product is dried, and the tourmaline fine particles are promoted to adhere to the inside of the silk fiber of the silk fiber product by wet heat treatment, and then soaping is performed. After that, a method for producing a tourmaline-containing silk fiber product to be subjected to finish treatment was adopted. In the above production method, a swelling agent for silk fiber products and a thermoreversible polymer as a protective colloid were allowed to coexist in the aqueous suspension.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tourmaline-containing silk fiber product which exhibits many of the functions and characteristics of tourmaline while maintaining excellent organoleptic properties of the silk fiber product, and a method for producing the same. Specifically, silk fiber products such as yarns, knits, woven fabrics and apparel composed mainly of silk fibers, while retaining the excellent sensory characteristics unique to silk fibers,
The present invention relates to a tourmaline-containing silk fiber product having many functions and characteristics such as tourmaline's excellent negative ion effect, far-infrared effect, deodorization, deodorization, antibacterial effect, and a method for producing the same.

[0002]

2. Description of the Related Art Generally, yarns constituting a fiber product are classified into long fibers and short fibers when roughly classified according to form. When those fibers are classified in terms of the raw materials, so-called natural fibers, such as cotton, hemp, silk, and wool, which are naturally produced, and rayon, vinylon, nylon, acrylic, and polyester, which are artificially produced from raw materials, are used. Classified as artificial fiber. The physical properties and quality of these textiles are governed by the yarn composition and aggregate structure that constitute them, and the range that can be corrected by post-processing such as dyeing and finishing is significantly restricted, and each has a unique experience from a long practical experience. It is well known that an evaluation has been obtained.

[0003] In particular, due to the leap of artificial fibers researched and developed using natural fibers as a model, consumption performance exceeding natural fibers has been widely recognized. Many consumers continue to adhere to fashionable natural fibers. For this reason, while maintaining the sensory characteristics of the silk fiber, a consumption characteristic comparable to the functionality of the ultra-fine polyester fiber is desired, and the epoxide cross-linking treatment technique by the two-phase method (for example, Japanese Patent Publication No. 2-53544).
As a result, the mutual development of the two textile industries has been achieved through intense quality battles that can be said to be unreasonable, while heterogeneous innovative technologies in each field of natural and man-made fibers are intermingled, such as the realization of washable silk commercialization by No. Was.

Although the electrical properties of tourmaline ore, which is called tourmaline used in the present invention, have been known for a long time, attempts to reproduce the functional properties of tourmaline ores on textiles have been cited. It is recently. Behind this, along with the development of fine-grain technology for tourmaline, a call for environmental conservation, and the desire to improve the lifestyle of clothing in the context of an aging society, comfort from the health and hygiene aspects and medical care In addition, the social needs for pursuing the effects of nursing care were directly motivated and narrowed down to one of the differentiated products, which seemed to have spurred the vigor of R & D.

[0005] Composite techniques of water-insoluble tourmaline fine powder (specific gravity of 3.0 to 3.3) obtained by pulverizing tourmaline ore and fibers can be generally classified into mixed spinning and post-processing similarly to other fiber processing techniques. . However, it is a common sense that natural fiber materials grown in living bodies are not biotechnologically modified by using tourmaline-containing soil or feed. At the time of molding, the technology of spinning by mixing tourmaline with the polymer compound dope that is the raw material is very efficient under the current situation where the spinning technology such as sea-island, division, liquid crystal and gel spinning is dramatically improved. Will be understood.

[0006] Both natural and artificial fibers are prepared by post-processing from a water-soluble polymer solution called a natural or artificial glue or a thermoplastic resin emulsion aqueous solution obtained by emulsion polymerization on a fiber product. A stable aqueous treatment solution is prepared by using tourmaline in combination with the binder component, and the fibers, yarns, fabrics or apparel are immersed in the aqueous solution, and a mangle or a mangle is formed so that a calculated amount of the aqueous solution remains on the textile. It is squeezed with a centrifuge and dried and fixed. In this case, if necessary, a treatment system may be used in combination with a cross-linking agent including a catalyst that reacts with a polymer substance during drying, a softening agent, a leveling agent, an antibacterial agent, and the like to prepare desired final physical properties and quality. Is a standard operation of fiber processing technology. Therefore, if the physical properties and quality of the processed fiber product are within the specified specified range, no particular problem is pointed out.

[0007] In fact, this fact can be confirmed from many disclosed patent publications. For example, Japanese Patent Publication No. 6-104926
In the publication, tourmaline is used in place of ceramics. In the case of artificial fibers, tourmaline is mixed and spun in a spinning solution to produce tourmaline-containing fibers. For producing excellent electret fibers by adhering tourmaline to the fibers. Further, vinylon (JP-A-9-188915)
), Rayon (JP-A-9-241919, JP-A-9-241919)
No. 0-121322, JP-A-11-43187, JP-A-11-117121), acrylic (Tokuleihei 10-1)
No. 83422) discloses a mixed spinning example relating to artificial fibers.

Further, a sock made of tourmaline-containing acrylic fiber is used by using the tourmaline-containing fiber produced according to the above method (Japanese Patent Application Laid-Open Nos. 10-183422 and 10-183422).
Many technical examples relating to secondary products, such as tourmaline-containing corset belt (JP-A-10-219504) and tourmaline-containing panty king (JP-A-11-152605), are also disclosed.

On the other hand, a multifunctional suit-type clothing using a layered sheet obtained by coating a nonwoven fabric or a woven or knitted fabric with tourmaline-mixed silicone rubber as a core material (Japanese Patent Application Laid-Open No.
100706, JP-A-11-100777), nursing sheets in which a synthetic fiber nonwoven fabric is impregnated or coated with a tourmaline-containing vinyl acetate resin (JP-A-11-10077)
No. 5). Further, by adding tourmaline to a system comprising a dispersant and an antifoaming agent using a water-soluble polymer paste as a protective colloid, cotton, polyester, rayon,
Spraying on cotton-like fibers such as feathers and wool, and through a cotton opening, an opener and a carding process, a futon (Japanese Unexamined Patent Publication No. 11-36171)
) Is also disclosed.

[0010] As a technique for imparting tourmaline to silk fibers including yarns, fabrics or secondary products, an aqueous solution of polypeptide produced by hydrolyzing fibroin obtained from silk fibers is used.
There is also disclosed a technique (JP-A-10-212456) in which a composition containing an aqueous binder and tourmaline which is cured by heating is applied using a coating technique.

[0011]

As already pointed out, even if hope is given to change the metal species contained in silk fibers or their intervening amounts by improving silkworm varieties and sericulture techniques, cocoon thread can be used. Tourmaline cannot be introduced into the constituent raw silk components. Therefore, at present, production of tourmaline-containing silk fiber products must rely on post-processing. In particular, the "Queen of Textiles", a thin fabric that uses long fibers that pursue high fashionability, follows the traditional techniques that have been handed down mainly to the delicate manual work of multi-product small-lot production. There are very few cases where fixing by tourmaline bonding with a thermoplastic resin is permissible because of the rough curing of the hand, even though the fiber product is made of silk spun in many places and the resin receiving capacity relatively increases.

[0012] Moreover, the durability of the fixed tourmaline via the bus Indah on the fiber surface will depend on the mixing ratio of the effective solid amount of tourmaline and binder to be applied. That is, the durability increases as the binder solid content is increased with respect to a fixed tourmaline amount, but on the other hand, the ratio of the surface of the tourmaline fine particles fixed on the fiber coated with the binder component is increased, and particularly, trimarin is increased. In this case, the generation of negative ions, which are the most noticed among the electrical characteristics, is suppressed. Further, as the amount of the binder decreases, the fixing strength of tourmaline on the fiber decreases, the resistance to rubbing during use deteriorates remarkably, and the tourmaline fine powder is inevitably dropped from the fiber product.

[0013]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors have conducted intensive research while organizing and summarizing peripheral technologies, and have selected tourmaline which is roughly divided into ultrafine particles, and selected the ultrafine particles. The present invention is completed by adsorbing and fixing tourmaline inside the silk fiber of a silk fiber product.

According to a third aspect of the present invention, there is provided a process for producing a tourmaline-containing silk fiber product, which comprises converting a swelling agent-containing aqueous suspension containing tourmaline fine particles into a silk fiber product such as a yarn, a knitted fabric, a woven fabric, and an apparel. A step of satiating, a step of drying the silk fiber product, a step of promoting fixation of tourmaline fine particles inside the silk fiber of the silk fiber product by wet heat treatment, a step of soaping the silk fiber product, and a finish after that This is a method including a step of processing.

The manufacturing method of the tourmaline containing silk textile product according to claim 4, wherein of the invention is a method of manufacturing a tourmaline containing silk fiber product of claim 3, wherein, Rise to silk textiles
This is a method in which the aqueous suspension containing a lubricant is saturated by an exhaustion method, a pad, a coating method, a printing method, or the like.

The manufacturing method of the tourmaline containing silk fiber product of claim 5, wherein out of the present invention is the manufacturing method of tourmaline containing silk fiber product of claim 3 or claim 4, wherein, swelling

In the production method of the present invention, the method of adsorbing and fixing the ultrafine tourmaline in the silk fiber is desirably to minimize the form of the silk fiber product, for example, the tension applied to the object during processing. For exhausted knits or secondary products, batch processing is suitable for exhaustion, and for processed objects such as woven fabrics, continuous processing such as padding, coating and printing is suitable. It is not limited.

[0020] Tourmaline ore is produced more abroad than in Japan, and its types are shawl (called iron tourmaline and iron tourmaline in Japan) and elbaite (lithia tourmaline, lithium tourmaline and lithium tourmaline in Japan). ), Drabite (in Japan, magnesite tourmaline,
(Also called magnesium tourmaline). It is well known that these ingredients are different, but all are used as ornamental jewelry. However, lithiatourmaline is most preferred as the tourmaline used in the present invention, which utilizes the effects of tourmaline's electrical properties, for example, piezo-electricity generated by pressure or pyro-electricity generated by heat. Usually, as the tourmaline applied for this purpose, those having a particle size of 2 μm or less, which are easily available on the market, are used. In general, when the particle size of the fine particles is 1 μm or less, they are called ultrafine particles. In some cases, it is pointed out that extremely small particle sizes cause a change in the intrinsic properties of the material, and the cost of the fine particles is also considered. If the particle size is 2 μm or less, a particle size having a distribution close to 1 μm can be recommended.

Although a slight difference in the tourmaline aqueous suspension applied to silk fiber products depending on the particle size or solid content of tourmaline is observed, this system itself is not necessarily stable. Rather, it is well known that long-term stability is poor even when a commonly used dispersing and emulsifying agent is used in combination, and that it is extremely unsuitable as a treatment liquid. In particular, even if a treatment solution of the exhaustion method is proposed as a countermeasure for mechanical shaking operation by stirring, shaking or injection of compressed air, etc., the impact on the object to be treated should be reduced as much as possible from the viewpoint of `` rubbing '' prevention. However, this method is not necessarily recommended as a processing condition for silk fiber products which is required to maintain a state close to standing during processing.

Therefore, in order to improve the stability of tourmaline in the aqueous suspension, it is necessary to use a protective colloid composed of a water-soluble polymer in the system. For example, chitosan,
A large number of fibroin, pullulan, xanthan gum, curdlan, collagen, polyvinyl alcohol, sodium alginate, carboxymethyl cellulose, starch, locust bean gum, guar gum and the like are also disclosed in the above publications. However, as the water-soluble polymer substance used in the present invention, a thermoreversible type having the property that the dissolved polymer precipitates or becomes cloudy when the aqueous solution is at a certain temperature or higher, and is redissolved at a temperature or lower. So-called macromolecules have been found to be suitable. These aqueous solutions, when heated, exhibit a unique phenomenon that manifests a gel structure called "thermal gelation", such as methylcellulose, hydroxypropylcellulose, partially saponified polyvinyl acetate, polyvinyl methyl ethyl, polyethylene oxide and polyvinyl oxalate. It has been observed in Zolidinone and others.

When a thermoreversible polymer aqueous solution is used as a protective colloid in a tourmaline aqueous suspension, the solubility of the thermoreversible polymer in water decreases when the temperature of the treatment solution rises to a gelling temperature, It is considered that the adsorption to silk fibers is relatively promoted, the concentration of tourmaline in the fiber layer region is increased, and the adsorption is more actively promoted, so that the adsorption speed of tourmaline is increased. Therefore, in order to promote the adsorption of tourmaline to silk fibers, it is possible to treat with a low bath ratio at a constant bath ratio and a low bath ratio at a constant tourmaline solid volume, and the operating environment is more improved. It will be advantageous. This phenomenon is reproduced in the continuous processing method and also in the dry heat drying step after the tourmaline-containing aqueous suspension is saturated, resulting in the promotion of the adhesion by the moist heat treatment that is subsequently adopted. The viscosity of the desired tourmaline-containing aqueous suspension needs to be adjusted according to the treatment method, and it is natural that the composition of the protective colloid composed of the thermoreversible polymer is changed as needed.

In the case of tourmaline having a particle size of about 1 to 2 μm, the adsorption of tourmaline to silk fibers requires a considerably long immersion at room temperature, but by heating or using a swelling agent for silk fibers in combination. Processing time can be reduced. In particular, as the swelling agent for silk fibers, nitrate, phosphate, thiocyanate, formate, etc., which have been known for a long time, potassium thiocyanate or barium and barium thiocyanate, which are relatively easy to control the swelling rate and handle the swelling agent easily, Calcium nitrate is suitable. In addition, pretreatment processing such as so-called "grafted silk" in which an acrylic monomer is polymerized in the gaps in the silk fiber and so-called "washable silk" which is crosslinked by heat and wet by a two-phase method using a bifunctional epoxide compound is performed. It has been confirmed that tourmaline adsorption to a silk fiber structure tends to be performed relatively well.

In the above exhaustion method, the exhaustion treatment at 100 ° C. or less is desirable. On the other hand, the tourmaline-containing treated textile product which is dried and heat-dried after being saturated is subjected to the batch heat treatment at 100 ° C. or less. However, if high-temperature steaming (HTS) is performed under atmospheric pressure in the range of 100 to 120 ° C., continuous processing becomes possible.

The silk fiber product thus adsorbed with tourmaline is subjected to the same post-processing as the conventional silk fiber product. That is, the protective colloid containing tourmaline and silk fiber swelling agent attached to the fiber surface can be sufficiently removed in the soaping step. In particular, thermoreversible polymers have good solubility at low temperatures and do not deviate from the requirements for washing silk fiber products. Therefore, the roughest hardening of the hand, which is the biggest drawback of the conventional method on the premise that the tourmaline is bonded and adhered by the binder, is completely eliminated.

The tourmaline-containing silk fiber product of the present invention is a product in which tourmaline fine particles are absorbed and fixed inside the silk fiber, so that the feeling of the silk fiber itself is completely maintained, but the tourmaline fine particles interposed inside the silk fiber itself. The tendency of whitening due to irregular reflection of transmitted light due to light is basically unavoidable. Also,
There is also a tendency to increase the wet feeling that can be presumed to be the effect of the contained tourmaline. As countermeasures against these, conventionally used polishing and smoothing agents and felt calendering can be considered, and it is thought that the use thereof is often required.

[0028]

(Embodiment 1) Hereinafter, a first embodiment of a method for producing a tourmaline-containing silk fiber product of the present invention will be described in detail. After scouring with a papain enzyme in a conventional manner, the 31 silk silk yarn bleached with thiourea dioxide is suspended in a skein-like shape on a stainless steel rod capable of moving up and down in a suspension tank. In a water-based suspension consisting of 2% by weight, 2% by weight of methylcellulose / sodium alginate (2: 1 blend), and 3% by weight of rodane soda,
It is immersed in a bath ratio of 1:40 at room temperature, the temperature is raised to 80 ° C. in 60 minutes while continuing the up-and-down motion, and the treatment is performed for 30 minutes. After draining the treatment liquid, according to a conventional method, washing with hot water, washing with water,
Soaped with 1 g / l surfactant and 2 g / l aqueous soap solution at 60 ° C. for 10 minutes, washed with hot water, washed with water, dehydrated and dried with a centrifuge, and increased by about 0.5% by weight in terms of absolute dry weight. Thus, a tourmaline-containing silk knitting yarn which reproduces the functional characteristics of tourmaline having the same feel and texture as untreated knitting yarn was obtained. No increase was observed in the aqueous suspension containing tourmaline without the addition of methylcellulose and rhodan soda.

Further, the above silk knitting yarn was prepared by using 1% by weight of tourmaline having a particle size of 2 μm or less, 3% by weight of xanthan gum, 2% by weight of an acrylic acid ester emulsion copolymer resin (solid content: 45% by weight), 0.5% by weight It was immersed in an aqueous suspension of a nonionic silicon emulsion (solid content: 30% by weight) at room temperature, filled to a squeezing ratio of 80% by weight, dried at 60 ° C, and heat-treated at 120 ° C. The treated silk knitting yarn gained about 3.1% by weight in terms of absolute dry weight. However, sticking between the skein yarns was remarkable, and the subsequent threading operation was difficult and did not endure practicality. Further, the feeling of the yarn was coarsely hardened, and the value as a silk yarn was not observed. In addition, in order to improve the softening effect, even if a fluorine compound or polyethylene emulsion is used in place of silicone in order to improve the softening effect, the sticking between fibers cannot be suppressed, and the effect of reducing the feeling of silk such as water generation and sliminess is manifested. You.
In addition, although the use of various cationic softeners varies depending on the type and the amount of the combined use, a tendency to promote the sedimentation of tourmaline is confirmed even when a water-soluble polymer aqueous solution is used as the protective colloid.

(Reference Example 1) A lining silk fabric for Japanese clothing called Kanuhachi silk (37 cm width, 2
6.5 m in length and 675 g in weight) were scoured and bleached according to a conventional method to prepare a kneaded fabric with a reduction rate of about 25% by weight (506).
g / Y anti). On the other hand, this knitted fabric is subjected to in-fiber polymerization treatment using an acrylic acid ester monomer mixture according to a conventional method, and is increased by about 25% by weight to rejuvenate to the fabric weight (675 g / Z). Separately prepared 325 mesh (particle size: about 15 μm), 5 g / 1 tourmaline, 30 g / l CMC as protective colloid, 30 g / l polyurethane oligomer (solid content: 15% by weight), 0.6 g of low-temperature dissociation catalyst
/ L (100% active ingredient) of each treated cloth was impregnated with the aqueous suspension, and each was squeezed to 90% by weight, dried, and dried.
C. for 2 minutes, and soaped and post-processed according to a conventional method. In any case, no remarkable increase is recognized, but adhesion of tourmaline particles to the fiber surface by the oligomer and
Due to the partial insolubilization of CMC used for the protective colloid, coarse curing of the fabric and sticking between the yarns constituting the fabric were observed,
The characteristics of the silk fabric disappear. In particular, it is observed that the Z counter is more paper-like than the Y counter.

The composition of the tourmaline-containing aqueous suspension is as follows:
Replace the protective colloid with a partially saponified product of polyvinyl acetate, a thermoreversible polymer, and replace the silk swelling agent with calcium nitrate or rodanbarium, using the exhaustion method, pad method, coating method and printing method. However, the adsorption of tourmaline into the fiber cannot be promoted. Therefore, the change in hand due to the resin is small, but the reproduction of the tourmaline function is not seen.

(Embodiment 2 ) The Y and Z counters prepared in Embodiment 2 were mixed in an aqueous tourmaline suspension having the following composition at a bath ratio of 1:40, 70 ° C., and 6 ° C.
After treatment in separate baths for 0 minutes, post-processing is performed according to the first embodiment. The treatment bath composition in this case is as follows. Particle size 1-2 μm Tourmaline: 5% owf (on the weight of fiber) Rodancari: 3% owf Humanoxypropylcellulose: 4% ows (on the weight of solution) Sodium alginate (low viscosity): 1% ows Y On the other hand, although the Z increase was slightly large, it was confirmed that tourmaline could be adsorbed into the fabric without impairing the sensory properties of the silk fabric, and that the tourmaline exhibited its functional properties. Also, with the wide decin treated with the epoxide, the pre-treated silk obtained good results, similarly to the so-called "grafted silk lining".

(Embodiment 3 ) A wide-width twill greige machine comprising four raw plain yarns 21 as warp yarns and six of the raw yarns 21 as weft yarns was scoured, bleached and dried according to a conventional method. An aqueous suspension consisting of 1% by weight of tourmaline having a particle diameter of 1 μm, 3% by weight of vinyl methyl ether as a protective colloid, and 2% by weight of rodin soda as a silk fiber swelling agent was padded at a squeezing ratio of 80% by weight, dried, and heated at a high temperature. Steam for 15 minutes at 100 ° C. in a steamer (HTS). Less than,
Post-processing is performed according to the first embodiment. The finished product treated by this method exhibited the functional properties of tourmaline remarkably while maintaining the silk texture.

(Embodiment 4 ) Six tussah yarns 35 deniers are twisted into three to form a knitting yarn and skeined. After scouring, bleaching, and drying by a conventional method, the resultant was immersed in a tourmaline-containing aqueous suspension in which the protective colloid and the silk fiber swelling agent used in Embodiment 4 were used in combination, and treated at 80 ° C. for 60 minutes. To finish post-processing. The texture of the knit woven from this tourmaline yarn has the feel of a knit manufactured from untreated yarn and a more stiff and flexible feel, and in addition to the advantages of the tourmaline's functions and characteristics being exhibited. Was.

(Reference Example 2) Tolmarin powder having a particle size of 2 μm: 10 g / liter Cationic water-soluble urethane oligomer: 40 g / liter Special acrylic silicone resin: 10 g / liter Chitanic acid gum derivative: 50 g / liter The mixture is kneaded with a disperser for 30 to 40 minutes to prevent aggregation and precipitation, stabilize the dispersion, and then coat the tourmaline gel thus obtained on a silk cloth by a padding method and dry. In the drying method, preliminary drying is performed using a 110 ° C. cylinder dryer, and then curing is performed using a 130 ° C. calendar.

No practical problems were found.
