Problems solved by technology

Due to the formation of covalent crosslinks between the cellulose molecular chains, compared with unfinished fabrics, the mobility between the basic structural units is limited, and the external force is more uneven, which will cause the strength of the fabric to decrease, which cannot satisfy consumers. It is of practical significance to improve the strength of anti-wrinkle finishing fabrics

Abstract

The invention relates to a method for preparing a crease-resistant cotton fabric from silica sol. The method comprises the steps of (1) sequentially dissolving catalysts and silicate in de-ionized water, adding an acid thinner to a solution, stirring for dissolving, immersing a cotton fabric in the solution, controlling the temperature at 10-30 DEG C for 1-48 hours, immersing and rolling twice till the liquid rate is 80%-85%, drying, washing, and drying again; and (2) immersing the cotton fabric in a crease-resistant finishing solution for 3-5 minutes, immersing and rolling twice till the liquid rate is 80%-85%, and finally, drying and baking. The tensile breaking strength of the fabric prepared by the preparation method is obviously improved, a problem of decrease in strength of an existing crease-resistant finishing fabric is obviously solved, and the fabric has wide application prospect and market prospect.

Description

technical field [0001] The invention belongs to the field of functional fabrics, in particular to a method for preparing wrinkle-resistant cotton fabrics by using silica sol. Background technique [0002] With the development of society and the advancement of science and technology, people's material life is becoming more and more abundant. Now people are no longer satisfied with food and clothing, but also begin to pursue rich spiritual culture. Consumers' requirements for the selection of fabrics have also changed. They are not limited to traditional colorful clothing, but pay more attention to the functionality and convenience of clothing. Because cotton fabric has the characteristics of comfortable wearing and good hygroscopicity, it is liked by people, but it is easy to wrinkle and difficult to care, so it cannot meet people's daily needs. Therefore, the anti-wrinkle finishing of cotton fabric has important practical significance. The main reason for the wrinkling of ...
