Abstract

The invention discloses novel environment-friendly composite slurry. The novel environment-friendly composite slurry is prepared from the following components in parts by weight: 5-10 parts of sodium alginate, 8-15 parts of PVA, 5-12 parts of polyacrylamide, 1-5 parts of other additives and 20-30 parts of deionized water. The invention further discloses a preparation method of the composite slurry. The composite slurry disclosed by the invention has a good sizing effect, has good stickiness and film-forming property on most fibers, and is good in flexibility, elasticity and wearing resistance, high in mechanical strength, pollution-free, biodegradable, easy to desize, simple in preparation process and low in cost.

Description

Technical field: [0001] The invention relates to the field of textile sizing, in particular to a novel environment-friendly composite size. Background technique: [0002] In order to endow the warp yarn with the ability to resist external mechanical force, improve the weavability of warp yarn, and ensure the smooth progress of the weaving process, a certain amount of size is often adhered to the surface of the sizing yarn, and a size film is formed after drying. [0003] Sodium alginate slurry is a pseudoplastic fluid with stable viscosity and is not affected by pH. It has the characteristics of low concentration and high viscosity, high surface tension, certain adhesion and film-forming ability, and good biodegradability. Poor elasticity. [0004] Polyvinyl alcohol film has the characteristics of high strength, good elasticity, and good wear resistance, and it is biodegradable. Polyacrylamide has good adhesion and film-forming properties, and its mechanical strength is gre...
