~ 1 3 3 3 7 3 9 POLYVINYL CHLORIDE FIBERS FOR ARTIFICIAL HAIR AND
- PRODUCTION OF THE SAME
The present invention relates to polyvinyl chlo-ride fibers for artificial hair and a process for producing the same. More particularly, the present invention relates to polyvinyl chloride fibers for artificial hair having good processability, function and cosmetic or beauty properties.
The fibers have a good feeling and are suitable for use as wigs, hair accessories and doll hair.
As artificial hair fibers, modacrylic fibers (e.g.
fiber comprising a copolymer of 50 % by weight of acrylo-nitrile and 50 % by weight of vinyl chloride), polyvinyl chloride fibers, polyvinylidene chloride fibers and poly-ester fibers are commercially available.
Since none of the conventional fibers satisfy all the properties required for hair fibers, e.g. heat resistance, curling properties, feeling and the like, hair products, e.g. wigs which satisfy various requirements have not yet been produced with a single kind of fiber. Until now hair products which have specific proper-ties corresponding to the kind of fiber used have been produced and used.

r A-Typical beauty properties required for artifi-cial hair fibers are as follows:
Properties relating to curling tl) Brush accommodation A direction of curling is easily changed with brushing and curling does not come loose.
(2) Maintenance of curling Spirally curled plural hairs (for example, 100 hairs) maintain their shape without drooping by their own weight.
(3) Maintenance of up-curling Plural hairs (for example, 100 hairs) are bundled and up-curled, that is the hairs are spirally curled upwardly with their roots down. When the up-curled hairs are swung, the hair bundle at the curled part does not come loose and the up-curled shape is maintained.
(4) Resiliency of spirally curled hair When the spirally curled hairs are suspended and swung up and down, they swing rhythmically while the direc-tion of curling does not shift right and left.
Organoleptic properties (5) Voluminess When brushing, the roots of hairs or skins do not appear and a natural puff suitable for each hair style is maintained.

~ ~ 333739 When the hair is h~ld between the fingers, it gives a soft and voluminous feeling, and when the hair is drawn between the fingers, it gives a smooth and slipping feeling.
(7) Gloss The hair has gloss similar to natural hair.
(8) Combability When the hairs are combed, there is no resistance in the middle portion, nor is the comb caught at the tips of the hairs and the comb moves through the hairs smoothly.
As described above, conventional artificial hair fibers have their own advantages and disadvantages.
For example, the modacrylic fibers have volumi-ness, feeling and gloss similar to natural hair and good combability although reasons for these properties are not known, while they have poor curling properties such that their bundle tends to be twisted when curled (poor mainte-nance of up-curling), their curling comes loose as time passes (poor maintenance of curling) or they have less resiliency. Because of these reasons, the modacrylic fibers are mainly used in products with a natural style (namely, hairs with slight wave or no wave).
The polyvinyl chloride fibers have good curling properties. For example, they are easily curled although the reason for this is not known, the curled hairs do not go out of shape as time passes, and when spirally curled, they have a r~ nt feeling. However, they lack the organoleptic '~
. - 4 -properties, that is, they have poor voluminess, or feeling and gloss close to synthetic fibers. Then, they are mainly used in products of wave style or straight style (in which only the tip parts are curled).
In view of the above circumstances, hair product makers have tried to use a combination or two or more kinds of synthetic fibers to produce the hair products which satisfy all the beauty characteristics. Since the fibers have different heat resistance, it is difficult to select adequate processing conditions. Further, the fibers have different hue and gloss, the hair products have an unnatural appearance.
One object of the present invention is to provide a synthetic fiber from which a hair product satisfying various beauty requirements can be produced.
Another object of the present invention is to provide a synthetic fiber which can provide a wide variety a hair styles.
According to the present invention, there is provided a vinyl chloride base fiber for artificial hair having an H-shaped cross section or a dumbbell-shaped cross section and a fineness of 40 to 70 deniers and which comprises a copolymer comprising 85 to 70% by weight of repeating units derived from vinyl chloride, 15 to 30% by weight of repeating units derived from acrylonitrile and 0 to 5% by weight of repeating units derived from at least -~.~
one ethylenically unsaturated "Y,.,~."~, copolymerizable therewith.
: In drawings which represent preferred embcdiments of the present invention:
Fig. l is an H-shaped cross section of the fiber of the present invention, and Fig. 2 is an dumbbell-shaped cross section of the fiber of the present invention.
The vinyl chloride units in the copolymer of the present invention impart a well knit curl shape which does not come loose as time passes to the artificial hair fibers and resiliency when the hairs are spirally curled. The acrylonitrile units impart feeling or voluminess close to natural hair and good combability.
When the content of the vinyl chloride units is less than 70 % by weight, the fiber does not have satis-factory curling properties, e.g. knitting of curl shape, maintenance of curling, resiliency and the like. When the content of the vinyl chloride exceeds 85 % or the content of the acrylonitrile units is less than 15 % by weight, the fiber does not have satisfactory organoleptic properties which are imparted by the acrylonitrile units, e.g. feeling and volllnin~s close to that of natural hair, or cnmh~h;l;ty.
The optionally contained ethylenically unsaturated monomer improves other properties,e.~. dyeing properties or processability of the fiber. Examples of such a ~ n~ are 'A
acrylic acid and methacrylic acid or their salts or esters, - vinylidene chloride, vinyl bromide, vinylidene bromide, methallylsulfonic acid and styrenesulfonic acid or their salts, acrylamide, vinyl acetate and the like.
The copolymer is preferably used independently, although it can be used in combination with a small amount of at least one other resin.
Examples of the other polymers are vinyl chloride resin, polyacrylonitrile, vinyl chloride-acrylonitrile copolymer, vinylidene chloride-acrylonitrile copolymer and the like. The amount of the other resin is determined according to the final use of the fiber, and is usually not more than 30 % by weight, preferably not more than 20 % by weight based on the total weight of the polymers.
The cross sectional profile of the fiber of the present invention is not critical. Although the cross sec-tion of a round shape, a horseshoe shape, a star shape or a Y shape may achieve the objects of the present invention, the fiber of the present invention preferably has a cross section of an H shape or a dumbbell shape as shown in Figs.
l and 2, respectively since the fiber with the H shaped or dumbbell shaped cross section has gloss, depth of color and flexibility which are close to natural hair.
The difference between the H shape and the dumb-bell shape is as follows:
~A
When the vertical size and the horizontal size of the cross section are "a" and "b", respectively, the H
shaped cross section has the ratio of b/a of less than 1.5 and preferably not less than 0.5 as shown in Fig. 1, and the dumbbell shaped cross section has the ratio of b/a of not less than 1.5 and preferably not larger than 3 as shown in Fig. 2.
The fineness of the fiber is not critical to the present invention, and any fiber having a fineness which is suitable for artificial hair can be used. Prefe-rably, the fiber has a fineness of 40 to 70 deniers. When the fineness is less than 40 deniers, the fiber may be too thin for a hair fiber so that curling maintenance may deteriorate. When the fineness is larger than 70 deniers, the fiber may be too thick and stiff for arti-ficial hair.
Now, production of the artificial hair fiber of the present invention is detailed.
The copolymer to be used in the present invention may be prepared by any conventional polymerization method in an aqueous system, e.g. suspension polymeri-zation or emulsion polymerization.
If desired, the other resin is added to the copolymer, and the copolymer or the mixture of the copolymer and the cther resin is dissolved in a solvent to form a solution having a concentration of from 25 to 35 ~. Examples of i~
1 33s739 the solvent are dimethylformamide, dimethylacetoamide, dimethylsulfoxide, acetone, acetonitrile, etc.
The polymer solution as such can be used as a spinning solution, although any conventional additive, e.g. titanium oxide, colloidal silica, calcium sulfate, aluminum hydroxide and the like~may be added to the spinning solution to improve the properties of the spun fiber.
The spinning solution is spun by a conventional wet or dry spinning method, dried and drawn followed by heating at a temperature of 100 to 140C by dry heat or at a temperature of 80 to 110C by wet heat.
The heating after drawing relieves strain of the fiber generated during drawing and is usually carried out for 0.5 to 5 minutes. When the dry he-at is applied at a temperature lower than 100C or the wet heat is applied at a temperature lower than 80C, the produced hair fibers easily shrink at a temperature at which the fibers aree set in the desired style, for example, 80 to 110C during the produc-tion of hair products from the fibers. When the dry heat is applied at a temperature higher than 140C or the wet heat is applied at a temperature higher than 110C, the fibers are fused together during heat treatment at such high tem-peratures.
The present invention will be illustrated by the following Examples, in which "%" is by weight unless other-wise indicated.
r~
` 1 333739 In the following Examples, the beauty properties of the fibers are evaluated as follows:
Fibers cut to a predetermined length or fibers cut to a predetermined length and arranged in parallel with each s other are wound around an aluminum pipe having a diameter of 10 to 40 mm according to the desired style and heat treated in an oven at a temperature of 80 to 110C or about 180C in the case of polyester fibers. Then, the curled fibers are fixed on a cap base with a sewing machine or a filling needle to produce an art1ficial head of hair and subjected to the evaluations on the properties listed in the beginning of the specification.

As described above, conventional artificial hair fibers have their own advantages and disadvantages.
For example, the modacrylic fibers have volumi-ness, feeling and gloss similar to natural hair and good combability although reasons for these properties are not known, while they have poor curling properties such that their bundle tends to be twisted when curled (poor mainte-nance of up-curling), their curling comes loose as time passes (poor maintenance of curling) or they have less resiliency. Because of these reasons, the modacrylic fibers are mainly used in products with a natural style (namely, hairs with slight wave or no wave).
The polyvinyl chloride fibers have good curling properties. For example, they are easily curled although the reason for this is not known, the curled hairs do not go out of shape as time passes, and when spirally curled, they have a r~ nt feeling. However, they lack the organoleptic '~
. - 4 -properties, that is, they have poor voluminess, or feeling and gloss close to synthetic fibers. Then, they are mainly used in products of wave style or straight style (in which only the tip parts are curled).
In view of the above circumstances, hair product makers have tried to use a combination or two or more kinds of synthetic fibers to produce the hair products which satisfy all the beauty characteristics. Since the fibers have different heat resistance, it is difficult to select adequate processing conditions. Further, the fibers have different hue and gloss, the hair products have an unnatural appearance.
One object of the present invention is to provide a synthetic fiber from which a hair product satisfying various beauty requirements can be produced.
Another object of the present invention is to provide a synthetic fiber which can provide a wide variety a hair styles.
According to the present invention, there is provided a vinyl chloride base fiber for artificial hair having an H-shaped cross section or a dumbbell-shaped cross section and a fineness of 40 to 70 deniers and which comprises a copolymer comprising 85 to 70% by weight of repeating units derived from vinyl chloride, 15 to 30% by weight of repeating units derived from acrylonitrile and 0 to 5% by weight of repeating units derived from at least -~.~
one ethylenically unsaturated "Y,.,~."~, copolymerizable therewith.
: In drawings which represent preferred embcdiments of the present invention:
Fig. l is an H-shaped cross section of the fiber of the present invention, and Fig. 2 is an dumbbell-shaped cross section of the fiber of the present invention.
The vinyl chloride units in the copolymer of the present invention impart a well knit curl shape which does not come loose as time passes to the artificial hair fibers and resiliency when the hairs are spirally curled. The acrylonitrile units impart feeling or voluminess close to natural hair and good combability.
When the content of the vinyl chloride units is less than 70 % by weight, the fiber does not have satis-factory curling properties, e.g. knitting of curl shape, maintenance of curling, resiliency and the like. When the content of the vinyl chloride exceeds 85 % or the content of the acrylonitrile units is less than 15 % by weight, the fiber does not have satisfactory organoleptic properties which are imparted by the acrylonitrile units, e.g. feeling and volllnin~s close to that of natural hair, or cnmh~h;l;ty.
The optionally contained ethylenically unsaturated monomer improves other properties,e.~. dyeing properties or processability of the fiber. Examples of such a ~ n~ are 'A
acrylic acid and methacrylic acid or their salts or esters, - vinylidene chloride, vinyl bromide, vinylidene bromide, methallylsulfonic acid and styrenesulfonic acid or their salts, acrylamide, vinyl acetate and the like.
The copolymer is preferably used independently, although it can be used in combination with a small amount of at least one other resin.
Examples of the other polymers are vinyl chloride resin, polyacrylonitrile, vinyl chloride-acrylonitrile copolymer, vinylidene chloride-acrylonitrile copolymer and the like. The amount of the other resin is determined according to the final use of the fiber, and is usually not more than 30 % by weight, preferably not more than 20 % by weight based on the total weight of the polymers.
The cross sectional profile of the fiber of the present invention is not critical. Although the cross sec-tion of a round shape, a horseshoe shape, a star shape or a Y shape may achieve the objects of the present invention, the fiber of the present invention preferably has a cross section of an H shape or a dumbbell shape as shown in Figs.
l and 2, respectively since the fiber with the H shaped or dumbbell shaped cross section has gloss, depth of color and flexibility which are close to natural hair.
The difference between the H shape and the dumb-bell shape is as follows:
~A
When the vertical size and the horizontal size of the cross section are "a" and "b", respectively, the H
shaped cross section has the ratio of b/a of less than 1.5 and preferably not less than 0.5 as shown in Fig. 1, and the dumbbell shaped cross section has the ratio of b/a of not less than 1.5 and preferably not larger than 3 as shown in Fig. 2.
The fineness of the fiber is not critical to the present invention, and any fiber having a fineness which is suitable for artificial hair can be used. Prefe-rably, the fiber has a fineness of 40 to 70 deniers. When the fineness is less than 40 deniers, the fiber may be too thin for a hair fiber so that curling maintenance may deteriorate. When the fineness is larger than 70 deniers, the fiber may be too thick and stiff for arti-ficial hair.
Now, production of the artificial hair fiber of the present invention is detailed.
The copolymer to be used in the present invention may be prepared by any conventional polymerization method in an aqueous system, e.g. suspension polymeri-zation or emulsion polymerization.
If desired, the other resin is added to the copolymer, and the copolymer or the mixture of the copolymer and the cther resin is dissolved in a solvent to form a solution having a concentration of from 25 to 35 ~. Examples of i~
1 33s739 the solvent are dimethylformamide, dimethylacetoamide, dimethylsulfoxide, acetone, acetonitrile, etc.
The polymer solution as such can be used as a spinning solution, although any conventional additive, e.g. titanium oxide, colloidal silica, calcium sulfate, aluminum hydroxide and the like~may be added to the spinning solution to improve the properties of the spun fiber.
The spinning solution is spun by a conventional wet or dry spinning method, dried and drawn followed by heating at a temperature of 100 to 140C by dry heat or at a temperature of 80 to 110C by wet heat.
The heating after drawing relieves strain of the fiber generated during drawing and is usually carried out for 0.5 to 5 minutes. When the dry he-at is applied at a temperature lower than 100C or the wet heat is applied at a temperature lower than 80C, the produced hair fibers easily shrink at a temperature at which the fibers aree set in the desired style, for example, 80 to 110C during the produc-tion of hair products from the fibers. When the dry heat is applied at a temperature higher than 140C or the wet heat is applied at a temperature higher than 110C, the fibers are fused together during heat treatment at such high tem-peratures.
The present invention will be illustrated by the following Examples, in which "%" is by weight unless other-wise indicated.

Then, the curled fibers are fixed on a cap base with a sewing machine or a filling needle to produce an art1ficial head of hair and subjected to the evaluations on the properties listed in the beginning of the specification.
The cross section of the fiber is observed with a scanning electron microscope.
