Description

Technical field

[0001] The present invention relates to a kind of polypropylene fiber, especially a kind of high hygroscopicity polypropylene fiber

[0002] Polyethylene glycol and polypropylene are blended and spun, and after post-treatment, modified polypropylene fibers are prepared to make the fibers contain strong hydrophilic groups, reduce the degree of tight aggregation of fiber macromolecules in the crystallization area, and form The micropores, gaps and capillary pores in the fibers are eliminated, and the prepared modified polypropylene fibers have good hygroscopicity. Especially the unique wicking effect makes it good in moisture conductivity and warmth retention, especially A highly absorbent polypropylene fiber. Background technique

[0003] Polypropylene fibers are produced by spinning polypropylene. Polypropylene is a polymer with high crystallinity. There are no hydrophilic groups in the main chain and side groups of its macromolecular structure. The fiber ...
