Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
86 words
A doll having hair comprising a multiplicity of multi-filaments of about 200 to 2,000 denier each comprising a multiplicity of mono-filaments of about 10 to 100 denier and comprising an acrylonitrile copolymer comprising 30 to 80% by weight of acrylonitrile units and 20 to 70% by weight units of at least one of vinyl chloride and vinylidene chloride; which filaments have an irregular surface unevenness of up to about 5 microns in distance from the bottom to the top thereof sufficient to reduce the shininess thereof.
