Problems solved by technology

Polyvinyl alcohol PVA is a good slurry, which has good adhesion to natural fibers and synthetic fibers, but its poor biodegradability will cause serious pollution to the environment
Polyacrylic slurry is environmentally friendly, easily degraded by microorganisms, and easy to recycle, but its application range is relatively narrow, and it needs to be modified before use.

Abstract

The invention provides nanometer titanium dioxide modified starch mixed slurry for textile use. The nanometer titanium dioxide modified starch mixed slurry comprises starch, PVA (polyvinyl acetate), acrylic ester, soybean protein, an organic silicone emulsion, sodium hydroxide, nanometer titanium dioxide and water; and the specific preparation method comprises the following steps: adding acetate starch to 5%-7% of nanometer titanium dioxide solution, and stirring at a high speed for 30-50 minutes so as to disperse the starch evenly, then adding the PVA, the acrylic ester, the soybean protein and the organic silicone emulsion, and adding sodium hydroxide to adjust the pH value to be 7-10; stirring at the speed of 150-200r / min for 30 minutes, heating to 80-90 DEG C and stirring at a constant temperature for 2-3 hours, so as to obtain the nanometer titanium dioxide modified starch mixed slurry for textile use. The sizing property of the nanometer titanium dioxide modified starch mixed slurry for textile use exceeds the sizing property of a mature formula with relatively high PVA content; and the nanometer titanium dioxide modified starch mixed slurry is good in degradation property and small in environmental burden, and can be applied to the sizing process of yarns and fabric.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, in particular to a nano titanium dioxide modified starch mixed slurry for textile. Background technique: [0002] Warp sizing is a key process in textile production. With the continuous emergence of various new fibers, the warp sizing process is also constantly updated. The three major elements of warp sizing are: textile size, equipment and technology, and the three complement each other. Among them, the raw materials and formula of textile size play a decisive role in warp sizing. Moreover, with the continuous development of science and technology, people's awareness of the ecological environment continues to increase, and the concept of green textile pulp has gradually entered people's field of vision. The production of convenient, reliable, low-cost, green and environmentally friendly textile pulp has become a Research topics for textile workers. [0003] The purpose of warp yar...
