Embodiment Construction

[0009] It can be seen from the accompanying drawings that based on the preparation of 15% or 30% masterbatch, accurately measure polyethylene glycol and carrier polypropylene powder, 0.05% calcium stearate to 0.1% calcium stearate, and 0.1% stabilizer 330 ~0.3% stabilizer 330, 0.04% degradation agent BTBP~0.1% degradation agent BTBP powder, and carrier powder are added to a high-speed mixer and mixed, melted and extruded by a twin-screw extruder, cooled, and granulated to produce modified sex masterbatch. During spinning, the dried modified masterbatch is uniformly mixed with fiber-grade polypropylene pellets at a total content of 1%-20%, melt-spun and then processed into modified fibers.

Abstract

The present invention is one kind of high-hydroscopicity polypropylene fiber and has the technological feature that into fiber level polypropylene material, modifying master batch in certain amount and comprising polyglycol as modifier and polypropylene powder dimethyl silastic, carrier polypropylene powder, lubricant calcium stearate, stabilizer 330 and degrading agent BTBP through high speed mixing, melting, extruding and pelletizing is added, and through common polypropylene fiber producing process the high-hydroscopicity polypropylene fibe is made. The present invention has the advantages of light weight, high strength, high elasticity, high anticorrosion, and unique humidity conductance and heat insulating performance owing to its core sucking effect.

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 ...
