Problems solved by technology

However, there are some defects in the performance of starch. The size film is brittle and hard, the elongation is small, and the adhesion to hydrophobic fibers is poor, which affects the quality of sizing. The performance can be improved by starch denaturation, and the warp sizing can be better completed without affecting environment, and low cost, easy to operate

Abstract

An energy-saving environment-friendly modified starch size is made from, by weight, 8 to 14 parts of butyl methacrylate, 6 to 10 parts of sodium pentachlorophenol, 3 to 5 parts of formaldehyde ethyl phenol, 10 to 16 parts of polyvinyl alcohol, 0.5 to 0.7 part of 2-naphthol, 6 to 12 parts of phosphate starch, 2 to 5 parts of nano-silicon nitride, 4 to 7 parts of polyoxyethylene lauryl ether, 20 to 32 parts of native starch, 5 to 8 parts of cerium ammonium nitrate, 2 to 4 parts of potassium persulfate, 2 to 3.2 parts of acrylic acid, 3 to 7 parts of guar gum modified hydroxymethyl, 3 to 7 parts of guar endosperm, 6 to 9 parts of modified starch, and 4 to 6 parts of corn starch. The energy-saving environment-friendly modified starch size is higher in permeability and wear resistance and helps improve loom efficiency, reduce pollution and energy consumption and save energy.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly modified starch slurry. Background technique [0002] The treatment of PVA desizing wastewater is difficult, and long-term accumulation will lead to ecological damage and environmental pollution. PVA slurry is regarded as "non-environmentally friendly slurry" because it is difficult to "biodegrade". Starch is currently the most used warp sizing material. It is a renewable resource with a low price and can be completely biodegraded. It is an energy-saving and environmentally friendly size. With the development of modern science and technology, starch and its products are more and more widely used, which drives the development of starch industry and promotes the in-depth research of starch modification technology. Starch is a kind of macromolecular compound with wide sources and low price, which can be biodegraded and regenerated. However, there are some defects in the performance of s...
