Abstract

The invention discloses FDY / POY (fully drawn yarn / partially oriented yarn) differential-shrinkage combined yarn prepared from biomass nylon 56 fibers / PTT (polytrimethylene terephthalate) fibers. The FDY / POY differential-shrinkage combined yarn is characterized by being prepared from biomass nylon 56 chips and PTT chips through spinning; the biomass nylon 56 fibers are FDY fibers and the PTT fibers are POY fibers, or, the biomass nylon 56 fibers are POY fibers and the PTT fibers are FDY fibers; the difference of the boiling water shrinkage rate of the biomass nylon 56 fibers and the boiling water shrinkage rate of the PTT fibers is not lower than 20%. According to the FDY / POY differential-shrinkage combined yarn prepared from the biomass nylon 56 fibers / PTT fibers, the tow surface is slightly and naturally crimped, the fiber hydrophilicity is improved, and the combined yarn can be applied to the development of imitated cotton and imitated silk textiles.

Description

technical field [0001] The invention relates to a FDY / POY different shrinkage mixed fiber yarn of biomass nylon 56 fiber / PTT fiber and a preparation method thereof. Background technique [0002] PTT fiber has the advantages of softness, good dyeing performance, good resilience, and stable chemical properties, and is widely used in various fields such as clothing and carpets. However, due to the lack of hydrophilic groups in PTT 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 PTT fibers. [0005] In order to solve the above problems, the present invention provides a kind of FDY / POY different shrinkage mixed fiber y...
