Abstract

The invention discloses a production method of a high-elongation lustrous polyester filament yarn, which comprises the steps of raw material melting and spinning, cross air blow cooling, false twisting texturing processing, oil cooling and winding. The production method is characterized in that the step of melting and spinning comprises the following actions: melting lustrous polyester chips as a raw material to form lustrous polyester melt, and injecting an ether additive with the mass content of 0.5%-0.95% into the melt. The production method of the high-elongation lustrous polyester filament yarn has the advantage of low production equipment requirements; and the produced high-elongation lustrous polyester filament yarn has high elongation at break greater than or equal to 40%, low boiling water shrinkage, few broken filament yarns and better product quality.

Description

technical field [0001] The invention relates to the field of fiber production, in particular to a production method of high-elongation glossy polyester filament. Background technique [0002] In the existing chemical fiber family, fiber products with high elongation at break include nylon and spandex, which are widely used, such as cords, transmission belts, ropes, hoses, tires, fishing nets, etc. The production process is limited, and its price is very high. At this stage, many companies are conducting research on polyester modification. The purpose is to find a polyester filament with a higher elongation at break to replace nylon and spandex, usually through two aspects. Means: 1. Add some modifiers or additives into the chips to obtain a modified melt; 2. Adjust the production equipment and processing technology. However, the elongation of polyester filaments at this stage does not exceed 35%, which cannot effectively replace nylon and spandex. Contents of the inventio...
