Abstract

The invention discloses an FDY / POY differential shrinkage blended filament of a biomass nylon 56 fiber / PBT fiber. The FDY / POY differential shrinkage blended filament is prepared through spinning biomass nylon 56 slices and PBT slices; the biomass nylon 56 fiber is an FDY fiber and the PBT fiber is a POY fiber, or the biomass nylon 56 fiber is the POY fiber and the PBT fiber is the FDY fiber; and a difference between the boiling water shrinkage of the biomass nylon 56 fiber and the boiling water shrinkage of the PBT fiber is not smaller than 30%. The FDY / POY differential shrinkage blended filament of the biomass nylon 56 fiber / PBT fiber has the advantages of fine natural curling surface and greatly improved hydrophilicity, and can be used in development of cotton-like and silk-like textiles.

Description

technical field [0001] The invention relates to FDY / POY different shrinkage mixed fiber yarn of biomass nylon 56 fiber / PBT fiber. Background technique [0002] PBT fiber has the advantages of good dyeing performance, good resilience and stable chemical properties, and is widely used in various fields such as clothing and decoration. However, due to the lack of hydrophilic groups in PBT fibers, the hydrophilicity of the fibers is relatively poor. [0003] Bio-based nylon 56 fiber is polymerized from bio-based pentamethylenediamine and adipic acid. It has good hydrophilic properties, resilience, and soft touch. It is a bio-based fiber material with broad application prospects. Contents of the invention [0004] What the present invention aims to solve is the problem of poor hydrophilicity of PBT fibers. [0005] In order to solve the above problems, the present invention provides a kind of FDY / POY different shrinkage blended filaments of biomass nylon 56 fiber / PBT fiber, w...
