[0007] Patent CN102363925A discloses a low-temperature soaping method, the pH value of the alkaline soaping agent is 10 + 0.5, while the alkalinity is too high, the reactive dyes on the fabric will break and fall off, and it will also increase the burden of washing, and usually need to be neutralized with acid. The soaping of this invention is only suitable for the dyeing stage. The dye is alkaline fabric, not universally adaptable
[0008] Patent CN102093508A discloses a low-temperature non-foaming soaping agent. Its formula contains high content of vinylpyrrolidinium, acrylic acid, maleic anhydride, and protective colloid. It does not contain any surfactant, although it can play a certain role in soaping. effect, but vinylpyrrolidine is a polymer compound with a large molecular structure, which makes it difficult to penetrate into the fabric, and a protective colloid is added to the formula, which affects the soaping effect. In addition, the soaping agent formula in the patent is not resistant hard water

Abstract

The invention relates to the technical field of textile printing and dyeing and provides a low-temperature soaping agent. The low-temperature soaping agent can soap surface dyeing of a dyed object at a lower temperature (60 DEG C), is not easy to foam, can chelate metal ions, has stronger combined dyeing capability and effectively prevents from staining. Meanwhile, the invention further provides a method for preparing the low-temperature soaping agent and an application of the low-temperature soaping agent. The low-temperature soaping agent is prepared from the following components in percentage by weight: 50-75% of maleic-acrylic copolymer, 5-15% of a surfactant, 0.1-0.5% of a de-foaming agent, 1-5% of ethanediamine di-o-hydroxyphenyl sodium acetate and the balance of de-ionized water.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a low-temperature soaping agent and its preparation method and application. Background technique [0002] Reactive dyes have complete color spectrum, bright color, low cost, and mature dyeing process. Therefore, more than 80% of cellulose fibers are dyed and printed with reactive dyes. There are many types of reactive dyes, various chemical structures, and different reaction efficiencies, but none of them can fully react with cellulose fibers, and there is a certain amount of unfixed dyes on the fibers after dyeing. In addition, while the fixed fiber is dyed, the dye will also be hydrolyzed, that is, the active group in the reactive dye is replaced by a hydroxyl group to form a hydrolyzed dye. These unfixed dyes and hydrolyzed dyes have very similar diffusion and adsorption properties to the original reactive dyes, so they are easily adsorbed on the fiber sur...
