Problems solved by technology

Moreover, it is difficult for a single-component surfactant to meet all requirements, and it needs to be compounded and synergized to meet the requirements.
However, compounded products often have layering problems

Abstract

The invention discloses a low-temperature degreaser for chemical fiber fabrics and a preparation method of the low-temperature degreaser. The low-temperature degreaser is prepared from the componentsin parts by weight: 30-40 parts of fatty alcohol-polyoxyethylene ether containing alkyl polyglucoside (APG), 20-30 parts of fatty alcohol-polyoxyethylene ether phosphate containing APG, 20-30 parts offatty alcohol-polyoxyethylene ether sulphonate containing APG, 5-15 parts of a greasy dirt dispersant, 5-15 parts of a builder, 0.2-1.0 part of a pH value regulator and 30-50 parts of soft water, wherein the fatty alcohol-polyoxyethylene ether containing the APG, the fatty alcohol-polyoxyethylene ether phosphate containing the APG and the fatty alcohol-polyoxyethylene ether sulphonate containingthe APG are three main components of the low-temperature degreaser, and the proportion of the three components can be changed. Alcohol ether in a structure of the fatty alcohol-polyoxyethylene ether containing the APG has good decontaminability, degreasing performance and dispersity, the APG in the structure has the outstanding characteristic of good affinity to greasy dirt, thus the greasy dirt is better adsorbed, and the low-temperature degreaser is evenly dispersed in processing liquid, and is very suitable for a low-temperature degreasing process of the chemical fiber fabrics.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing auxiliaries, in particular to a low-temperature degreasing agent for fabric dyeing and finishing and a preparation method thereof. Background technique [0002] Polyester is a major category of synthetic fibers. Because of its excellent setting performance, polyester has excellent deformation resistance after repeated washings, so it is widely used in clothing, textile and other industries. Especially superfine polyester, which not only has the characteristics of high strength, good elasticity, excellent wear resistance, and stable size of ordinary polyester, but also has the advantages of silk fabric, good air permeability, and comfortable wearing, so it is loved by people. Polyester fibers are inevitably stained with spinning oil during spinning and drawing, and may also be stained with other oils such as spindle oil, black machine oil, gear oil, and white mineral oil during later wea...
