Abstract

The invention relates to a bleaching method of a textile material and textile products. The bleaching method includes following steps: mixing refining agent, whitening agent and water to obtain refining liquid, soaking the textile material into the refining liquid, and holding temperature at 80-110 DEG C for 10-60min; soaking the textile material treated by the refining liquid in bleaching liquid, and holding temperature at 90-110 DEG C for 60-120min. The bleaching method can effectively avoid fluorescence nonuniformity; under the circumstance that when consumption of the whitening agent is lower to 0.0001%-0.3% of mass of the textile material, the method still can ensure the whitening agent to be adsorbed uniformly on the surface of the textile material, so that the consumption of the whitening agent can be reduced, quality of the textile products is improved, and production cost is lowered effectively.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for bleaching textile materials and textile products. Background technique [0002] The textile industry is an important economic support industry in my country, and bleaching is a very important link in the dyeing and finishing of textiles. It can improve the appearance quality of textiles, improve wettability, permeability, etc. The quality of bleaching will directly affect the quality of textiles. Affects the color quality of the final product. [0003] At present, with the development of social economy, people have higher and higher requirements for color diversity, so the textile industry has higher and higher requirements for the whiteness range of textile products. However, in the traditional bleaching and whitening process, the phenomenon of uneven fluorescence is very easy to occur, so that the whiteness of the bleached textile products is uneven, and finally t...
