Problems solved by technology

Due to the high non-cellulose content in the jute fiber, the jute fiber is thick and hard, and the spun jute yarn has a lot of hairiness on the surface and low strength, and in the sizing process before weaving, the jute yarn still uses traditional PVA as the sizing agent. pulp, which brings great inconvenience to the subsequent weaving process, which seriously restricts the development of jute fiber as high and mid-grade textiles

Abstract

The invention discloses sizing slurry for jute yarn. The sizing slurry comprises PVA (polyvinyl acetate) slurry, grafting starch and polyacrylamide slurry, wherein the weight ratio of the PVA slurry to the grafting starch is 1:(1-4), and the weight ratio of the mixture of the PVA slurry and grafting starch to the polyacrylamide slurry is (3-15):1. In the invention, the polyacrylamide slurry is mixed with the PVA slurry and grafting starch in an optimal ratio to realize a perfect coordination effect; and through the invention, the adhesive force of the slurry can be increased, and the slashing flexibility can be obtained, thereby being favorable for splitting yarn and keeping serosa integrity, and improving the comprehensive performance of the slurry as well as the slashing quality.

Description

technical field [0001] The invention relates to the weaving field of jute yarn, in particular to a sizing material for jute yarn. Background technique [0002] With the rising prices of raw materials such as cotton fiber and chemical fiber, people began to demand other fibers that can replace cotton and chemical fiber. Among them, hemp fiber, especially jute fiber, has attracted more and more attention because of its low price. At the same time, because jute fiber itself has characteristics such as moisture absorption, breathability, antibacterial and mite suppression, and biodegradability, many researchers have begun to study jute fiber, hoping to develop multifunctional and high value-added products. Due to the high non-cellulose content in the jute fiber, the jute fiber is thick and hard, and the spun jute yarn has a lot of hairiness on the surface and low strength, and in the sizing process before weaving, the jute yarn still uses traditional PVA as the sizing agent. si...
