Definitions

  • the present invention relates to polyvinyl chloride 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, functions and cosmetic or beauty properties such as feeling when used for wigs, hair accessories and doll hair.
  • modacrylic fibers e.g. fiber comprising a copolymer of 50 % by weight of acrylonitrile and 50 % by weight of vinyl chloride
  • polyvinyl chloride fibers polyvinylidene chloride fibers
  • polyester fibers are commercially available. From US-4012346 it is also known to use fibers made from copolymers comprising up to 90% by weight of vinyl chloride.
  • Typical beauty properties required for the artificial hair fibers are as follows:
  • the conventional artificial hair fibers have their own advantages and disadvantages.
  • the modacrylic fibers have voluminess, feeling and gloss similar to the 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 maintenance 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 resilient feeling. However, they lack the organoleptic 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).
  • 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 of hair styles.
  • a vinyl chloride base fiber for artificial hairs 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 monomer copolymerizable therewith.
  • 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 give resiliency when the hairs are spirally curled.
  • the acrylonitrile units impart feeling or voluminess close to the natural hair and good combability.
  • the fiber When the content of the vinyl chloride units is less than 70 % by weight, the fiber does not have satisfactory curling properties such as 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, such as feeling and voluminess close the natural hair, or combability.
  • the optionally contained ethylenically unsaturated monomer improves the properties such as dyeing properties or processability of the fiber.
  • examples of such monomer are 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 of other resins.
  • 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 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 section 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. 1 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 the natural hair.
  • 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 in the present invention, and any fiber having the fineness which is suitable for the artificial hair can be used.
  • the fiber has the fineness of 40 to 70 deniers.
  • the fineness is less than 40 deniers, the fiber may be too thin as the hair fiber so that the maintenance of curling may be deteriorated.
  • the fineness is larger than 70 deniers, the fiber may be too thick and stiff for the artificial hair.
  • the copolymer to be used in the present invention may be prepared by any of conventional polymerization methods in an aqueous system such as suspension polymerization or emulsion polymerization.
  • the other resin is added to the copolymer, and the copolymer or the mixture of the copolymer and the other resin is dissolved in a solvent to form a solution preferably of a concentration of from 25 to 35 %.
  • a solvent examples include dimethylformamide, dimethylacetoamide, dimethylsulfoxide, acetone, acetonitrile, etc.
  • the polymer solution as such can be used as a spinning solution, although any of conventional additives such as 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.
  • any of conventional additives such as 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 140°C by dry heat or at a temperature of 80 to 110°C by wet heat.
  • the heating after drawing relieves strain of the fiber generated during drawing and is carried out usually for 0.5 to 5 minutes.
  • the dry heat is applied at a temperature lower than 100°C or the wet heat is applied at a temperature lower than 80°C, the produced hair fibers easily shrink at a temperature at which the fibers are set in the desired style, for example, 80 to 110°C during the production of hair products from the fibers.
  • the dry heat is applied at a temperature higher than 140°C or the wet heat is applied at a temperature higher than 110°C, the fibers are fused together during heat treatment at such high temperature.
  • Fibers cut to a predetermined length or fibers cut to a predetermined length and arranged in parallel with each other are wound around an aluminum pipe having a diameter of 10 to 40 mm according to styles and heat treated in an oven at a temperature of 80 to 110°C or about 180°C in 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 artificial hair of the head 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.
  • Table 2 includes the accommodation of the fibers to various styles. These results indicate that the fibers of the present invention can be arranged in various styles.
  • Example 2 In the same manner as in Example 1, a spinning solution was prepared and spun through an orifice having dumbbell shaped pores, coagulated, washed with water, dried and drawn followed by heat treating with dry heat at 125°C to obtain fibers having a fineness of 55 deniers and a cross section of dumbbell shape.
  • Table 2 includes the accommodation of the fibers to various styles. These results indicate that the fibers of the present invention can be arranged in various styles.
  • Example 2 In the same manner as in Example 1, a spinning solution was prepared and spun through an orifice having round pores, coagulated, washed with water, dried and drawn followed by heat treating with dry heat at 125°C to obtain fibers having a fineness of 55 deniers and a cross section of horseshoe shape.
  • acetone 85 % of the copolymer prepared in Example 1 and 15 % of a copolymer of 50 % of vinyl chloride, 49 % of acrylonitrile and 1 % of sodium styrenesulfonate were mixed and dissolved to prepare a spinning solution Then, the a spinning solution was spun through an orifice having dumbbell shaped pores, coagulated, washed with water, dried and drawn followed by heat treating with dry heat at 130°C to obtain fibers having a fineness of 55 deniers and a cross section of horseshoe shape.
