1,189,784. Self-crimpable conjugate filaments. KANEGAFUCHI BOSEKI K.K., and SNIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 8 Jan., 1968 [14 Jan., 1967 (2)], No. 1093/68. Heading B5B. A two-component self-crimpable conjugate filamentary material is produced by simultaneously spinning through a common orifice a first component consisting of an aliphatic homopolyamide and a second component consisting of a mixture of from 50% to 97% by weight of an aliphatic homopolyamide and from 3% to 50% by weight of an aromatic polyester-ether alone or together with an aromatic polyester, the weight ratio of said polyester-ether to said polyester being from 100/0 to 3/97. The second component may be prepared by melting, mixing and stirring the sub-components thereof in molten condition. Polyamides used include aliphatic homopolyamides such as nylon 6, nylon 66, nylon 610 and nylon 11. Aromatic polyesters include polyalkylene terephthalate. Aromatic polyester-ethers include polyethylene oxybenzoate, polypropylene oxybenzoate, polyethylene- and polypropylene-vanillate. |
