Abstract

See full text

An artificial hair bundle (10) which comprises a first artificial hair (1) made of a polyester resin and a second artificial hair (5) made of a polyamide resin blended together. The first artificial hair (1), which is made of polyethylene terephthalate and polybutylenne terephthalate, has a sectional diameter almost the same as natural hair and a bending rigidity almost the same as natural hair. This bending rigidity ranges from about 6.5 to about 7.8 x 10-3 gfcm2/strand at a humidity of 40%. The first artificial hair (1) regulates the converging properties of the second artificial hair (5) so that the first and second artificial hairs (1,5) behave in the same way as natural hair.
