The introduction of spinning chemical fiber oil and the development status of textile chemical fiber oil at home and abroad

10. Domestic textile oil enterprises and oil development

China's textile chemical fiber oil industry started late, beginning in the early 1980s, but it has developed rapidly, and now it has a certain scale and foundation. The development, technology and production of oil agents have formed a relatively complete supporting system. As far as finished polyester oil is concerned, domestic polyester filament has accounted for 60% of the total fiber in recent years, and the use of polyester filament oil has accounted for 45% of the total oil. Polyester filament oil is generally composed of a variety of base oils and various surfactants, need to take into account lubricity, antistatic, heat resistance, viscosity, so that contradictory performance requirements are balanced to meet, sometimes as many as a dozen components. Therefore, it is necessary to study the properties of the components, master the microemulsification technology, compound formulation and matching chemical fiber production process in the development of polyester filament oil agent.

At present, the localization rate of DTY winding oil is about 80%, the localization rate of POY oil is about 50%, FDY fine denier oil is about 40%, and the localization rate of polyester industrial filament oil is less than 30%. Polyester staple fiber oil agent not only to meet the production of chemical fiber factory, but also to meet the needs of textile factory after processing, development is difficult, the localization rate is low. Shanghai Petrochemical, Liaoyang Petrochemical, Yizheng Chemical fiber and other large chemical fiber factories, raw materials for high-quality polyester, fast tensile speed, most of the selection of oil from Japan Takemoto oil company and Matsumoto company imported, accounting for 80% of the total amount; Another kind of small chemical fiber plant, the raw materials are waste and polyester waste bottles of large chemical fiber plants, the drawing speed is slow, and the antistatic agent octadecyl dimethyl hydroxyethyl ammonium nitrate, fatty alcohol polyoxyethylene ether and glycerol are used in the early stage of the ****** generation of short fiber oil. In the 1990s, the advent of alkyl phosphate esters as antistatic agents and the development of surfactant industry drove domestic polyester staple fiber oils into the second generation, and the production capacity of small chemical fiber factories expanded rapidly and the drawing speed increased, so basically the second generation of domestic oils were selected.
