Research and application progress of localization of polyester filament oil agents
China's polyester filament industry is developing towards high quality,multi-variety and high yield.At the same time,it puts forward higher requirements for oil agents.At present,the pre-spinning oil agents and industrial silk oil agents with high-quality requirements mainly rely on imports,which greatly increases the production cost of chemical fiber enterprises.The continuous development of domestic polyester filament oil agents that meet the requirements is conducive to the development of China's textile industry.In this paper,the research progress of the domestic application of the most widely used polyester POY,DTY,FDY and industrial yarn oil agents was reviewed in detail,including composition and requirements,industry overview,type,formulation and effect,to provide a reference for the development of high-quality and large-scale domestic oil agents in China in the future.There are few hydrophilic groups in polyester macromolecules,and it is easy to produce static electricity in the spinning process.The use of oil agents is conducive to post-processing,improving textile efficiency and ensuring product quality.Polyester filament oil agents are mainly composed of smoothing agents,emulsifiers,stabilizerss,antistatic agents and cluster agents.It is necessary to give the fiber excellent wear resistance,cluster,smoothing,wetting and antistatic properties in the high-speed spinning process to meet the production process requirements.At present,China mainly imports high-quality POY,FDY and industrial filament oil agents from Japan,Germany and the United States.Imported products have the characteristics of high quality,many types and wide application range.The scale of domestic oil agent companies represented by Zhejiang Transfar Co.,Ltd.,Tianjin Gongda Textile Additives Co.,Ltd.and Zhejiang Huangma Technology Co.,Ltd.has gradually expanded and the quality has been gradually improved,and products that can replace imported oil agents have been continuously developed.Some large chemical fiber companies such as Xin Feng Ming Group,Tongkun Group and Hengyi Group are also increasing the research and development of oil agents.At present,DTY oil agents have been domesticated.Compared with civil filament,the polyester industrial filament has the characteristics of high strength,wear resistance,lightweight and good stability.It is widely used in cords,conveyor belts,seat belts,cables and airbags,etc.It has high added value.Industrial filaments put forward higher requirements for the performance of oil agents.At present,the domestic rate of industrial filament oil agents in China is not high,and the development of high-quality oil agents for special purposes should be strengthened in the future.The research and development of polyester filament oil agents is developing in the direction of environmental protection,anti-spatter,anti-oxidation and good stability,and continuously meets the market requirements of porous fine denier,full extinction,colored silk,bionic and high-strength industrial silk.In the future,it should be combined with new technologies and new materials to continuously improve quality and reduce costs.
