Abstract
A doll supports a quantity of rooted hair fabricated to provide a posable or cold setting characteristic. The posable hair is formed of an amorphous thermoplastic material preferably having a high molecular weight in a compound including plasticizers, heat stabilizers and lubricants. The material is formed to provide a combination of glass transition temperature characteristic and hardness to produce the cold setting or posable quality.
Claims7
A posable hair doll comprising:
- a doll head having a hair-supporting portion thereon;
- and
- a plurality of posable synthetic hair filaments each formed of a posable nonmetallic material being cold formable into a desired shape or set and tending to retain said desired shape or set when released and being restorable to their previous shape by heatless brushing or combing,
- said synthetic hair filaments being formed of an amorphous thermoplastic material having a glass transition temperature between zero degrees centigrade and plus twenty degrees centigrade and a hardness between eighty and one hundred Shore A Durometer.
For use in combination with a doll, a plurality of hair filaments formed of a material comprising a compound of not less than 60% nor more than 75% by weight of a high molecular weight polymer or copolymer of polyvinyl chloride;
- and not less than 20% nor more than 35% by weight of a plasticizer;
- and not less than 3% nor more than 10% by weight of a heat stabilizer;
- and not less than 0.5% nor more than 1.5% by weight of a lubricant.
For use in combination with a doll, a plurality of hair filaments formed of a material comprising a compound of not less than 60% nor more than 75% by weight of a high molecular weight polymer or copolymer of polyvinylidene chloride;
- and not less than 20% nor more than 35% by weight of a plasticizer;
- and not less than 3% nor more than 10% by weight of a heat stabilizer;
- and not less than 0.5% nor more than 1.5% by weight of a lubricant.
