Embodiment Construction

[0017] The present invention provides a chemical fiber desizing agent, including nonionic surfactant, fatty amine polyoxyethylene ether, hydroxy carboxylate, organic anionic surfactant and solvent; wherein, the nonionic surfactant includes iso Fatty alcohol polyoxyethylene ether or fatty alcohol polyoxyethylene ether, the organic anion surfactant includes secondary alkylsulfonate sodium or fatty alcohol polyoxyethylene ether sulfate.

[0018] The mass percentage of the nonionic surfactant is 5% to 18%; the mass percentage of the fatty amine polyoxyethylene ether is 10% to 20%; the mass percentage of the hydroxycarboxylate is 2% to 10% ; The mass percentage of the organic anion surfactant is 10%-28%; the mass percentage of the solvent is 29%-71%, and the solvent includes water.

[0019] When the organic anionic surfactant is sodium secondary alkyl sulfonate, the mass percentage of the nonionic surfactant is 5% to 10%, and the nonionic surfactant is isomerized fatty alcohol poly...

Abstract

The invention provides a chemical fiber desizing agent and a preparation method and use method thereof. The chemical fiber desizing agent has the advantages of no phosphorus, no alkylphenol ethoxylatecompounds (APEO), high biodegradability, high desizing rate and the like, can be used for a cold pile process and a flat-width desizing and washing process, reduces a large amount of steam energy consumption and the like, saves water, electricity and steam in comparison with a traditional high-temperature (100 DEG C) desizing process, better meets the environmental protection requirements and lightens the sewage treatment burden. Through the use method of the chemical fiber desizing agent, the desizing rate of terylene memory-like cloth reaches a level 8-9, wherein the highest level is level9.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a chemical fiber desizing agent, a preparation method and a use method thereof. Background technique [0002] The commonly used size for weaving polyester in chemical synthetic fibers is polyacrylate, which is an acrylate copolymer size. Since the size contains ester groups, it has a certain similarity in structure with polyester molecules containing the same group, so it has a strong affinity for polyester. Polyester itself does not contain impurities, but a small amount (below about 3%) of oligomers exists during the synthesis process, so it does not require strong pre-treatment like cotton fibers. As a desizing and refining process, its main purpose is to remove the oil added during fiber spinning, the size added during weaving, coloring dyes, and oil stains and dust contaminated during transportation and storage. However, if the desizing of polyester fabrics is not clean o...
