Abstract

Belonging to the technical field of textile yarn sizing, the invention in particular relates to an environment-friendly slurry and a sizing process thereof. The environment-friendly slurry includes the following components by weight: 10 parts of FL0LINE SIZE P, 95-105 parts of starch, 22-27 parts of acrylic acid, and 0.2-0.4 part of FLOSIZE PA 760 H. The environment-friendly slurry provided by the invention is conducive to loom moisture regain absorption, the yarn is soft, weaving stop is reduced, the slurry also has good film-forming properties and permeability, can completely replace PVA slurry, and is environment-friendlier. The invention also provides a sizing process of the slurry, and the process consists of: adding the well proportioned components into a mixing bucket in order, performing heating, adding assistants and covering the slurry tightly; then injecting the slurry into a sizing machine size tank, keeping the squeezing roller pressure at 18-21KN, setting the size tank temperature at 90-93DEG C, setting moisture regain at 8.5%, and the sizing machine speed at 55-60m / min, and when the yarn reaches a predetermined length, completing sizing. The slurry provided by the invention is suitable for sizing to all varieties.

Description

technical field [0001] The invention belongs to the technical field of textile sizing, and in particular relates to an environment-friendly size and a sizing process thereof. Background technique [0002] Warp sizing is a key process in weaving, and the effect of sizing directly affects the efficiency of the loom and the quality of the finished product. At present, the sizing materials for warp yarn sizing mainly include three types: starch, PVA, and acrylic acid. Starch has good film-forming properties and is easy to desizing; however, the starch size is not strong enough and not wear-resistant. PVA size film has strong strength, good toughness, and good fluidity of slurry, but PVA is difficult to desizing and causes great environmental pollution. Acrylic acid has low viscosity and good fluidity, but the price is high. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an environmentally fri...
