JP4896517B2 - Fiber bundles for hair and hair ornament products made of regenerated collagen fibers and human hair - Google Patents

Description

  The present invention relates to a fiber bundle for hair and a hair ornament product in which regenerated collagen fibers and human hair are blended in which all the Fritz-free performance, permanent wave performance and tactile sensation are improved and the overall quality is better than that of human hair products.

In the field of headdress products, human hair is optimal and widely used as a hair material because of the nature of the product. However, unlike actual human hair, it does not change, so deformation due to friction, so-called frits, accumulates, and there is a problem in durability, which is not a satisfactory quality. On the other hand, a regenerated collagen fiber described in (Patent Document 1) has been proposed as a human hair substitute raw material, but has no permanent wave performance because it does not have a cystine bond like human hair. Further, regenerated collagen fibers imparted with cystine bonds are known in (Patent Document 2) and (Patent Document 3). However, when permanent wave treatment is applied to regenerated collagen fibers with a cystine bond, the shape can be imparted but the ability to retain the shape (setting property) is extremely weak, and subsequent drying and washing with water (including shampoo washing) are repeated. As a result, the shape was quickly removed, making it difficult to use for hair materials such as wigs, weaving, hairpieces or doll hair. In addition, regarding the tactile sensation, the surface of the regenerated collagen fiber does not have a cuticle peculiar to human hair, so that a tactile sensation peculiar to human hair cannot be realized satisfactorily. As described above, there is actually no headdress product that satisfies all the requirements for Fritz-free performance, permanent wave performance, and touch.
JP 2001-800920 A Japanese Patent Application No. 09-186794 Japanese Patent Application No. 10-312044 On the other hand, hair ornament products that combine human hair with synthetic fibers such as modacrylic fiber, saran fiber, and vinyl chloride fiber have been studied, but the heat resistance of the fiber is human hair. Therefore, when the temperature of a dryer, iron, etc. is adjusted to human hair, there is a possibility of heat deterioration, which is not practical. Furthermore, when the synthetic fiber is used, the synthetic fiber once heat-set is not easily returned to its original shape, so the style change is not easy, and the reason is not clear. There was a problem that it could not be corrected even if it was given.

  The object of the present invention is to use a fiber bundle blended with regenerated collagen fibers and human hair as a hair raw material that exceeds human hair, and the overall quality of frits-free performance, permanent wave performance, and touch is better than human hair products. To provide hair bundles and hair ornament products for hair.

That is, the present invention relates to a fiber bundle for hair was blended with 30% to 70% by weight and human hair 70-30 wt% regenerated collagen fibers and head decorative products made therefrom.

  It is preferable that the regenerated collagen fiber has a fineness of 30 to 100 dtex.

  The regenerated collagen fiber is preferably treated with a monofunctional epoxy compound and an aluminum salt.

  The aluminum content of the regenerated collagen fiber is preferably 1 to 10% by weight.

  By using the fiber bundle and headdress product that blends the regenerated collagen fiber and human hair of the present invention, the accumulation of Fritz, which is a defect of human hair products, is improved, and the permanent wave performance, which is a defect of the regenerated collagen fiber, is combined. High quality headdress products can be provided.

The present invention blends regenerated collagen fibers and human hair to make up for the defects of both quality, so-called fritz-free performance that does not accumulate frits, permanent wave performance, and human hair-like good tactile feel. Good quality fiber bundles for hair and hair ornament products can be obtained. Blending ratio is preferably 30 to 70 wt% and human hair to 70-30% by weight of regenerated collagen fibers. Most preferably 40 to 60% by weight of the regenerated collagen fiber and human hair 60 to 40% by weight. If the regenerated collagen fiber is less than 10% by weight, the frits-free performance is insufficient, while if it exceeds 90% by weight, the permanent wave performance and the tactile sensation are insufficient. The fineness of the regenerated collagen fiber is preferably 30 to 100 dtex. Preferably it is 40-90 dtex, More preferably, it is 50-80 dtex, Most preferably, it is 50-70 dtex. If it is less than 30 dtex, it tends to be too soft for hair. Moreover, when it exceeds 100 dtex, it tends to become hard. Typical headdress products include weaving products, wig products, bulk products, hairpiece products, etc., but the present invention is not limited to the above products.

  A general method for making a weaving product is to sew a bundle of fibers of a predetermined length with a sewing machine for a wig to form a bundle of fibers processed into a lumbar shape called a web or an eyelash, and wrap this around a pipe. Then, heat treatment is performed to give a desired shape such as straight or spiral to make a weaving product. The heat treatment is preferably performed in a steam atmosphere, and any known method can be used without limitation. Specifically, a general steam set or warm water set can be used.

  Weaving products are knitted in a net shape along the scalp and sewn to the hair, or attached to the scalp and the hair with an adhesive or the like mainly.

  A common method of making a wig product is, for example, by sewing a fiber bundle of a predetermined length with a sewing machine for a wig to make a fiber bundle processed into a lumbar shape called a web or an eyelash, and winding this around a pipe Heat treatment to give a desired shape such as straight, curl or spiral. Sew the eyelashes on the net and film sewn into the shape of the head to finish the wig product.

  The general method of making a bulk product is the same as the general method of making a weaving product, except that the bulk product is processed in a fiber bundle state without lashing. Bulk products are used with their own hair attached with adhesive or braid.

A general method for making a hair piece product is, for example, by sewing a fiber bundle of a predetermined length with a sewing machine for a wig to make a fiber bundle processed into a waist shape called a web or an eyelash, and winding this around a pipe Heat treatment to give a desired shape such as straight, curl or spiral. Sew the eyelashes on the net sewn in the shape of a drawstring bag and finish it into a hair piece product. Hair piece products are used by wrapping their own hairs in a dumpling form by wrapping them in a drawstring bag.
The above is a general product creation method, and is not limited to these methods.

  The human hair used in the present invention is human hair that is generally available to the public and is not particularly limited.

The regenerated collagen fiber of the present invention is not particularly limited, but collagen that has been solubilized by an alkali solubilization method or an enzyme solubilization method using, for example, cattle and other bark as a raw material, such as lactic acid, hydrochloric acid, and acetic acid. Using an aqueous solution dissolved with an acid, the aqueous solution is spun from a spinning nozzle into an aqueous solution of an inorganic salt such as sodium sulfate, sodium chloride, or ammonium sulfate to form fibers, and an organic crosslinking agent such as a monofunctional epoxy compound or an aluminum salt. A regenerated collagen fiber that has been made water-resistant by reacting with a metal salt such as is typical, and can be suitably used.
As the alkali solubilization method, the method described in (Patent Document 4), which is an improved method of the conventionally known alkali solubilization method, is used, and as the enzyme solubilization method, For example, the methods described in (Patent Document 5) and (Patent Document 6) can be used. Further, the alkali solubilization method and the enzyme solubilization method may be used in combination.
Japanese Examined Patent Publication No. 46-15033 Japanese Patent Publication No.43-25829 Among the organic crosslinking agents, monofunctional epoxy compounds are preferred because they are less colored and have the effect of lowering the water absorption of the resulting fibers. Specific examples of the monofunctional epoxy compound used here include, for example, ethylene oxide, propylene oxide, butylene oxide, isobutylene oxide, octene oxide, styrene oxide, methyl styrene, epichlorohydrin, epibromohydrin, glycidol, and the like. Olefin oxides, glycidyl methyl ether, butyl glycidyl ether, octyl glycidyl ether, nonyl glycidyl ether, undecyl glycidyl ether, tridecyl glycidyl ether, pentadecyl glycidyl ether, 2-ethylhexyl glycidyl ether, allyl glycidyl ether, phenyl glycidyl ether , Cresyl glycidyl ether, t-butylphenyl glycidyl ether, dibromophenyl glycidyl ether, benzyl glycidyl ether Glycidyl ethers such as polyethylene oxide glycidyl ether, glycidyl formate, glycidyl acetate, glycidyl acrylate, glycidyl methacrylate, glycidyl benzoate, glycidyl amides, and the like. It is not limited to. Further, among the metal salts, aluminum salts are preferred because they are less colored and the resulting regenerated collagen fibers are moistened when wet, improving the wet feel. In addition, you may use the method etc. which are described in (patent document 7) etc. as a conventionally improved method of the aluminum salt process. JP, 6-173161, A There is no restriction in particular in the aluminum salt used here, For example, aluminum sulfate, aluminum chloride, basic aluminum chloride, basic aluminum sulfate, etc. are mention | raise | lifted. Here, basic aluminum chloride and basic aluminum sulfate are represented by the following (formula 1) and (formula 2).

Al (OH) nCl3-n (Formula 1)
Al2 (OH) 2N (SO4) 3-n (Formula 2)
(In the formula, N is 0.5 to 2.5)
In the present invention, it is more preferable to use a solubilized collagen aqueous solution to form fibers by spinning into an inorganic salt aqueous solution, and then to treat with a monofunctional epoxy compound and an aluminum salt. By such treatment, there is little coloring, the water absorption rate is lowered, the wet feeling is improved, the heat resistance is improved, and the wet heat treatment at a higher temperature is possible. The temperature can be made higher.
In this invention, it is preferable to process so that the aluminum content contained in the fiber after a process may be set to 1 to 10 weight%, and a more preferable range is 3 to 9 weight%. If it is less than 1% by weight, the wet feeling becomes poor, and if it exceeds 10% by weight, the treated fiber becomes hard and the texture is impaired.

EXAMPLES Next, although this invention is demonstrated further in detail based on an Example, this invention is not limited only to this Example.
The fineness, fritz-free performance, permanent wave performance, and tactile evaluation shown in the examples were evaluated by the measurement methods shown below.

(Fineness)
The fineness was measured in an atmosphere at a temperature of 20 ± 2 ° C. and a relative humidity of 65 ± 2% using a motorcycle bro fineness measuring device Denier Computer (registered trademark) DC-77A (manufactured by Search). After 20 fibers were cut into 20 cm and each fiber was measured one by one, the average value of these was taken as the fineness.

(Fritz-free performance)
Create a fiber bundle with a weight of 30 g, wrap it in your hand and rub it until it becomes a hairball shape. After that, unravel it with your hand and keep it straight until it passes. Then, it is soaked in water for 5 minutes or longer and carefully passed through a comb so as to extend the deformation of the fiber. Remove from the water, remove the moisture on the surface of the fiber and carefully stretch it with a comb and let it dry naturally. According to the criteria of Table 1, the state of the fiber after drying was evaluated visually.
