Study On Nylon High Speed Spinning Finishes And Application

The Nylon high speed spinning finishes , a kind of auxiliaries used in Nylon spinning ,mainly takes effect of lubricant, cohesive and antistatic properties in spinning and false twisting process. It is very hard to prepare Nylon high speed spinning finishes because of Nylon fiber's special structure and high speed concomitancy with high temperature in spinning and false twisting process. So there is a marked disparities in Nylon high speed spinning finishes researching between China and some advanced countries .Based on the specialty of Nylon high speed spinning process and special requirement for the spinning finishes ,the paper studied the monomer synthesizing and prescription optimizing after considering other factor and finally prepared the Nylon high speed spinning finishes .The physical and chemical properties and applicant properties of the finishes were studied and compared with product abroad .Based on the special requirement of Nylon high speed spinning process for finishes monomer, the paper studied the properties of copolyether monomer with different initiator structure, copolyether chain structure, degree of polymerization, distribution of EO and PO. Based on the special requirement of Nylon high speed spinning process for finishes ,the functional compounding copolyether used as main ingredient of finishes were synthesized which including different acid and alcohol initiator , degree of polymerization, molar ratio of EO/PO.The Nylon high speed spinning finishes was prepared based on the requirement of Nylon high speed spinning process for finishes and compared with product abroad . The paper also studied the properties of the finishes such as frictional ,wetting ,antistatic ,thermal resistant ,oil membrane intension and surface properties .Finally ,the TPA-98 finishes was used in product line of chemical fiber plant by studying the spinning tension ,evenness and spinnability of spinning procedure and spinning tension ,snow quantity , spinnability and product quality .Moreover the paper also studied the influence of OPU and storage time on POY performance and the method was brought forward.
