摘要： PROBLEM TO BE SOLVED: To obtain a braided cord of polyamide crimped fiber, having high stainpoofness and capable of maintaining it for a longterm. SOLUTION: This highly stainproof braided cord is composed of a yarn comprising a sheath-core type conjugate fiber consisting of a polyamide as the core component and, as the sheath component, a polyamide composition blended with a fluoropolymer so as to be 0.05-5.0 wt.% in fluorine content of the composition with the weight ratio of the core to sheath being (40-90):(10-60) on the fiber cross section. This braided cord is obtained by braiding the crimped fiber consisting of the above conjugate fiber with the triroval cross section having a section deformation degree of 2-4 and a number of crimps of 4-6/inch.

SOLUTION: This crimped fibers comprises fibers including sheath and core type conjugated fiber consisting of 40-90 wt.% core part composed of a polyamide and 10-60 wt.% sheath part composed of a polyamide composition obtained by blending a fluorine-containing polymer such as a random copolymer consisting essentially of tetrafluoroethylene and ethylene, polychlorotrifluoroethylene, polyvinylidene fluoride and a copolymer of vinylidene fluoride and tetrafluoroethylene, with the polyamide so that the fluorine content may be 0.05-5.0 wt.%. Further, the crimped fiber has crimp characteristics such as 10-40% crimp stretch ability, 6-12/in number of crimp. The fouling of a carpet is easily removed by laundry, when the crimped fiber is used as a carpet, and the crimped fibers are also useful for a string, a curtain, a fabric for a bag, a sheet, etc.

摘要： PURPOSE:To obtain the subject bulky yarn free from separation of single filaments, having uniform distribution of single filament looseness in longitudinal direction and suitable for intermingled yarn by aligning synthetic fibers having different elongation at break, subjecting to crimping, etc., and blending the fibers. CONSTITUTION:Plural kinds of synthetic fibers such as nylon 6 fiber having an elongation difference of >=5% are produced by changing the draw ratio. The fibers are aligned, stretched preferably at a stretching ratio of 2-12%, heated at 150-200 deg.C, crimped, relaxed in an over-feeding region and blended in an air-entangling treatment region to obtain the objective bulky yarn.
