Abstract

The invention discloses an environment-friendly and efficient refining agent for cotton and a preparation method thereof. The environment-friendly and efficient refining agent is prepared from gleditsia sinensis saponin, a non-ionic surfactant, an anionic surfactant, a chelating dispersant, an organic silicon de-foaming agent, a hydrogen peroxide stabilizing agent and water. The environment-friendly and efficient refining agent for the cotton, disclosed by the invention, takes the gleditsia sinensis saponin as one of main body raw materials, and can have a remarkable synergistic effect with acompound system composed of the anionic surfactant and the non-ionic surfactant, so that the surface tension can be remarkably reduced at room temperature; meanwhile, the environment-friendly and efficient refining agent integrates osmosis, emulsification, chelating, dispersion and hydrogen peroxide stabilization and has multi-effects; a pre-treatment technology becomes simple, reasonable and economical and energy saving and environmental protection are realized.

Description

technical field [0001] The invention relates to an environmentally friendly and high-efficiency scouring agent for cotton and a preparation method thereof in the technical field of textile printing and dyeing. Background technique [0002] Scouring is a very important process in the pretreatment process of printing and dyeing. The purpose is to remove impurities contained in cotton fibers, such as cotton seed hulls, cotton wax, pectin, protein, unremoved size in the desizing process, and stained fabrics. Oil stains, etc. In the past 20 years, with the popularization of high-efficiency short-process pretreatment processes such as alkali-oxygen-bath and cold pad batch, increasing scouring speed, saving energy consumption, reducing water consumption, and shortening the process flow have become urgent problems to be solved. It is necessary to seek rapid penetration , strong emulsifying power, strong chelating ability, high detergency, high temperature resistance, concentrated a...
