Abstract

A textile size composition is prepared from modified starch (20-90%) and specia nano material (0.05-5%) which is chosen any one of SiO2, TiO2, Al2O3 and ZrO2. Its advantages are high stability, shortdissolving time and high effect of benefiting weaving.

Description

【Technical field】 [0001] The invention belongs to a textile warp treatment agent, and relates to a technical solution of a textile size composition. 【Background technique】 [0002] The existing modified starch size, because of its brittle size film and poor flexibility, cannot meet the requirements of textile yarn sizing when used alone, and often needs to be mixed with a certain amount of chemical auxiliary size, such as polyvinyl alcohol. The addition of polyvinyl alcohol slurry was once considered to be an ideal slurry due to its good adhesion to fibers, toughness of the size film, and good wear resistance. With the increase of textile varieties and the improvement of quality requirements, its shortcomings are gradually exposed: the size is unstable, easy to delaminate, and the pulping time is long, resulting in a huge waste of energy and equipment; the size film is too strong, making warp sizing difficult. Difficult to separate yarns, easy to form regenerated hairiness;...
