Artificial hair articles and process for the preparation thereof

Claim 2

The artificial hair strands of claim 1 wherein said particles of a cross-linked copolymer are of spheroidal shape.

Claim 3

The artificial hair strands of claim 1 wherein said fiber forming synthetic thermoplastic polymer is selected from polyolefins, polyesters, polyamides, polyvinyl chloride, polyacylonitrile, and acrylonitrile-vinyl chloride copolymer.

Claim 4

The artificial hair strands of claim 1 wherein said radically polymerizable di- or tri-ethenically unsaturated cross-linking agent is selected from di-vinyl benzene, di-vinyl toluene, tri-vinyl benzene and di-vinyl sulfone.

Claim 5

An artificial hair article in the form of a fall, hair piece or wig comprising a base element to which are attached a multiplicity of bundles of artificial hair strands, said artificial hair strands consisting essentially of a fiber-forming synthetic thermoplastic polymer, said synthetic thermoplastic polymer containing uniformly dispersed therein and incorporated therewith 0.1 to 10 percent by weight of particles of a cross-linked copolymer of a. at least one radical polymerizable monoethylenically unsaturated monomer selected from the group consisting of styrene, vinyl toluene, methyl vinyl pyridine, methacrylonitrIle, acrylonitrile, methacrylic acid, methacrylic acid alkyl esters, acrylic acid, acrylic acid alkyl esters, vinyl acetate and vinyl chloride, and b. a radical polymerizable di- or tri-ethylenically unsaturated cross-linking agent, said cross-linking agent (b) being present in an amount of 0.5 to 30 percent by weight based on the weight of said cross-linked copolymer, said particles being 0.01 to 2 microns in size, said strands having on the surface thereof, along their entire length, a uniformly distributed fine slit-like grooved pattern.

Claim 6

The artificial hair article of claim 6 wherein the diameter of said strands is within the range of 0.08 - 0.12 mm, said thermoplastic polymer containing 0.5 - 4 percent by weight of said cross-linked copolymer particles.

Claim 7

The artificial hair article of claim 6 wherein said particles of a cross-linked copolymer are of spheroidal shape.

Claim 8

The artificial hair article of claim 6 wherein said fiber-forming synthetic thermoplastic polymer is selected from polyolefins, polyesters, polyamides, polyvinyl chloride, polyacrylonitrile, and acrylonitrile-vinyl chloride copolymer.

Claim 9

The artificial hair article of claim 6 wherein said radically polymerizable di- or tri-ethenically unsaturated cross-linking agent is selected from di-vinyl benzene, di-vinyl toluene, tri-vinyl benzene and di-vinyl sulfone.
