Abstract

The invention discloses a nonionic polyether type high-molecular surfactant as well as a preparation method and application thereof. The nonionic polyether type high-molecular surfactant is obtained by carrying out esterification modification or etherification modification on secondary hydroxyl of a chain polyether type high-molecular surfactant, and the nonionic polyether type high-molecular surfactant is used as a soaping agent for cotton fabrics. The nonionic polyether type high-molecular surfactant prepared by the invention has relatively strong adsorption performance, complexing ability, colloid protection performance and the like, can have very strong binding ability with dye in a soaping process, and has very strong removal effect on flooding on the surface of a fabric, so the washed dye stably exists in a washing solution, and the fabric is not stained any more, so the flocculent precipitation condition is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of surfactant preparation, in particular to a nonionic polyether polymer surfactant and a preparation method and application thereof. Background technique [0002] The application proportion of reactive dyes in cellulose fiber dyeing continues to expand, but after dyeing with reactive dyes, some dyes do not react with fibers to form covalent bonds, but stick to the surface of fabrics after hydrolysis to form floating colors, which affects the fastness of dyed fabrics. Fabrics generally require soaping after dyeing. The so-called soaping means that after the fiber fabric is printed and dyed, in order to improve its color fastness and brightness, use soap or detergent solution to wash the unfixed dyes, dyeing aids, printing paste, etc. The processing technology of cleaning under boiling conditions. During the soaping process, the unfixed dyestuff is gradually transferred from the fabric to the net bath, form...
