Multifunctional high-temperature oil removing levelling agent

Abstract

The invention discloses a multifunctional high-temperature oil removing levelling agent, which specifically contains the following raw materials by weight: 225-275 parts of polyethylene glycol, 90-110 parts of oleic acid, 0.9-1.1 parts of hypophosphorous acid, 2.7-3.3 parts of sulfuric acid, 63-77 parts of fatty alcohol-polyoxyethylene ether and 18-22 parts of rare earth. The sulfuric acid and the phosphorous acid serve as catalysts to enable mixed polyethylene glycol and oleic acid to perform esterification to produce corresponding esterified substance with high-efficiency decontamination and oil removing effects. The esterified substance, an appropriate amount of the fatty alcohol-polyoxyethylene ether and the rare earth are mixed in a compound mode. Principally by means of assistant-dyeing property of the rare earth, a compound agent having the functions of levelling property, dispersity, decoloration, synchronous dyeing property and the like apart from the oil removing function isobtained. Obtained fabrics have the advantages of being pure and normal in color tone, full, good in sense of touch and the like. The multifunctional high-temperature oil removing levelling agent increases first-rate product rate of dyeing machine fabrics, enables oil removing and level dyeing to be performed in the same bath, greatly shortens technological process, lowers production cost, and achieves the beneficial effect of energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing of woven fabrics, and specifically refers to a multifunctional high-temperature degreasing and leveling agent. Background technique [0002] Leveling agent is an essential chemical auxiliary in the dyeing and finishing process of woven fabrics. At present, the textile printing and dyeing industry at home and abroad generally uses high-temperature dyeing agents mixed with polyether-type nonionic or polyether-type anionic surfactants and bulking agents. Leveling agent, which can solubilize and disperse disperse dyes, has a certain leveling effect; however, in the spinning and weaving process of various fabrics such as polyester, it is usually necessary to add a certain amount of mineral oil, lubricant, whitening agent, etc. Various oil agents such as mineral oil, in the subsequent dyeing and finishing process, if the oil agent is not removed, it is very easy to cause dyeing defects such...

[0002] Leveling agent is an essential chemical auxiliary in the dyeing and finishing process of woven fabrics. At present, the textile printing and dyeing industry at home and abroad generally uses high-temperature dyeing agents mixed with polyether-type nonionic or polyether-type anionic surfactants and bulking agents. Leveling agent, which can solubilize and disperse disperse dyes, has a certain leveling effect; however, in the spinning and weaving process of various fabrics such as polyester, it is usually necessary to add a certain amount of mineral oil, lubricant, whitening agent, etc. Various oil agents such as mineral oil, in the subsequent dyeing and finishing process, if the oil agent is not removed, it is very easy to cause dyeing defects such as stains and oil spots; due to the lack of removal of the existing leveling agent Oil function, in the traditional process, the fabric needs to add degreaser before dyeing to carry out the degreasing step, which not only increases the process flow and production cost of the fabric, but also various auxiliary agents such as degreaser and leveling agent The large amount of addition also increases the burden of discharge treatment; at present, there is also dyeing and degreasing in the same bath method, which needs to add leveling agent and degreasing agent in the same bath at the same time, and there are also problems such as inconvenient operation and high cost
