Abstract

The invention relates to phosphate and a production process thereof and belongs to the technical field of dyeing and finishing of fabrics. The phosphate is characterized by being prepared from raw materials according to a specific ratio and by being prepared by the following steps of: adding fatty alcohol into a reaction kettle; cooling by introducing cold water into the reaction kettle under stirring; adding phosphorus pentoxide in batches; reacting for 4 hours by controlling the reaction temperature to be 80+2 DEG C; cooling to about 40 DEG C; and discharging and packaging to obtain the phosphate. Compared with the prior art, the phosphate has the characteristics of high wettability, permeability, dispersibility, emulsification decontaminability, antistatic property, anti-rust property, washability, no harm to fiber and the like. According to a sodium sulfite scouring and bleaching process, coagulation of other surfactants is inhibited and a white spot phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing and finishing. Background technique [0002] This additive belongs to anionic surfactants. Before that, the permeating refining agents used in the fabric pretreatment process could not achieve satisfactory results in the short process, cold pad batch, and steaming processes due to poor alkali resistance. Therefore, it is imperative to develop a phosphate-based refining penetrant with strong alkali resistance and high permeability. The company's research institute has strong technical reserves and human resources, and has successfully developed phosphate alkali-resistant refining agents by using complete instruments and equipment and using the auxiliary factory as a test base. And taking advantage of the good performance of this product, a series of refining agent products have been formulated to meet the needs of the printing and dyeing industry for alkali-resistant additives.
