Abstract

The invention discloses FDY/POY different shrinkage combined filament yarn of biomass nylon 56 fiber/PET fiber.The combined filament yarn is characterized by being prepared by spinning biomass nylon 56 fiber slices and PET slices; the biomass nylon 56 fiber is FDY fiber and the PET fiber is POY fiber, or the biomass nylon 56 fiber is POY fiber, and the PET fiber is FDY fiber.The difference between the boiling water shrinkage of the biomass nylon 56 fiber and that of the PET fiber is equal to or larger than 30%.According to the obtained FDY/POY different shrinkage combined filament yarn of the biomass nylon 56 fiber/PET fiber, the surfaces of tows curl slightly and naturally, hydrophily and softening property of the tows are obviously improved, and the FDY/POY different shrinkage combined filament yarn can be used for developing imitated cotton and imitated silk fabric.

Description

technical field [0001] The invention relates to a FDY / POY different shrinkage mixed fiber yarn of biomass nylon 56 fiber / PET fiber and a preparation method thereof. Background technique [0002] Different shrinkage mixed fiber yarn is a product formed by mixing fibers with different thermal shrinkage rates. When this type of mixed fiber yarn is heat treated in the subsequent dyeing and finishing process, the filament with a large thermal shrinkage rate will shrink to form a core filament, while the filament with a small shrinkage rate will produce fine and natural curls and float on the surface of the tow. , the tow cross-section will present a fluffy structure, and its fabric will have a full-bodied appearance. However, the current different shrinkage mixed fiber yarn is mainly formed by blending the fully drawn yarn (FDY) and pre-oriented yarn (POY) of PET fiber. PET fiber has high strength, high modulus, stable size, stable chemical properties, etc. advantage. However,...
