Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific embodiments.

[0018] The preparation method of environment-friendly textile size of the present embodiment comprises the following steps:

[0019] The first step is to mix hydroxypropyl modified starch with silicon powder, add it to deionized water, add sodium hydroxide and methanol, perform hydrolysis, dry and purify to obtain nano-silica modified starch, wherein, hydroxypropyl modified starch: The mass ratio of silicon powder: sodium hydroxide: methanol is: 100:5:0.1:0.2;

[0020] In the second step, soybean protein is added to a sodium hydroxide solution with a concentration of 0.2%, stirred at a constant speed at 45°C for 15 minutes, and then the precipitate is filtered to obtain a protein slurry;

[0021] The third step, according to the weight ratio, 72 parts of nano-silica modified starch, 15 parts of protein slurry, 11 parts of polyacrylate emulsion, 2 parts of polysiloxane modi...

Abstract

The invention relates to a preparation method for environment-friendly type textile sizing agent. The preparation method comprises the following steps: mixing hydroxypropyl modified starch and silicon powder and adding a mixture into de-ionized water; adding sodium hydroxide and methanol; carrying out hydrolysis, and drying and purifying to obtain nano silicon dioxide modified starch; adding soybean protein into a sodium hydroxide solution and agitating at 45 DEG C at uniform speed for 15 minutes; filtering and removing sediment to obtain a protein sizing agent; pouring the nano silicon dioxide modified starch, the protein sizing agent, polyacrylate emulsion and an organic silicon de-foaming agent into an agitator to be agitated and mixed to obtain the environment-friendly type textile sizing agent. The sizing agent prepared by the invention has good film forming property and permeability; the sizing performance is good and a formula does not contain polyvinyl alcohol, thus the environment-friendly type textile sizing agent is very environment-friendly.

Description

technical field [0001] The invention relates to an environment-friendly textile slurry preparation method. Background technique [0002] Warp sizing is a key link in weaving engineering. The purpose of sizing is to improve the wear resistance of the yarn, reduce hairiness, increase the strength of the yarn appropriately, and reduce the elongation, so as to withstand the mechanical force of the warp yarn during the weaving process. Improve yarn weavability. [0003] At present, the sizing materials for warp yarn sizing mainly include three major sizing materials: starch, polyvinyl alcohol (PVA) and polyacrylic acid. Starch is a natural polysaccharide polymer. The size has good film-forming properties, strong affinity with natural fibers, and easy desizing; however, starch size is not strong enough in sizing, not wear-resistant, and has insufficient affinity with polyester fibers. Polyvinyl alcohol size film has high strength, good flexibility, and good slurry fluidity, but ...
