Abstract

A technology for producing cationic sliver includes vacuum drying CDP chips with 0.23-0.3% of SIPM content which controlling the precrystallizing temp and time, screw smelting and spinning, cooling while winding to obtain primary fibres (7-17 dtex), bundling, oil-bath drafting, two-pass steam stretching, curling while finishing oil, thermal shape fixation, making ribbons (88 mm in average length), carding, and making sliver. Its advantages are soft handle, high antistatic nature, and high dyeability.

Description

technical field

[0001] The invention relates to the field of chemical fibers, and mainly relates to a process for making cationic wool tops. Background technique

[0002] As we all know, worsted wool spinning mills mostly produce polyester wool products, and in blending with wool, conventional polyester strips are basically used. Conventional polyester, the largest variety of synthetic fiber, has many problems in the development of simulated differentiated fibers, such as poor dyeability, poor hygroscopicity, and high modulus, due to its regular molecular chain and no coloring groups. There is a big gap between it and natural wool. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a process for making cationic wool tops with improved fiber dyeability and hygroscopicity, improved comfort and wearability, and improved polyester wool-like level.

[0004] The technical solut...
