Problems solved by technology

Moreover, there are many researches on the specific process of acrylic fiber or cellulose fiber in the production and development of flat fiber at home and abroad, while there are few researches on the forming of flat polyester fiber, and there are fewer researches on product transformation on the basis of flat cross section. The production of flat heterodyed polyester lacks theoretical and practical guidance

Abstract

The invention discloses a method for preparing metachromatic linear flat polyester filaments, which includes the steps of drying, melting, spinning, cooled oiling and hot-rolled winding. In the step of drying, crystallization temperature is 170 DEG C, crystallization time ranges from 15 minutes to 30 minutes, drying temperature is 175 DEG C, drying time ranges from 8 hours to 10 hours, the intrinsic viscosity of slices is lower than 0.005dL / g, and water content is below 20ppm. According to the technical scheme, thick-and-thin yarns are ingeniously applied to the flat filaments by means of non-uniform stretching on a conventional one-step spinning and drawing combination machine, the characteristics of flat sections and longitudinal non-uniform thicknesses are sufficiently combined, a fabric made of the flat filaments has the unique appearance effect of silk rain grains, and the defect of single style of a fabric made of pure flat fibers is overcome.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a method for preparing differently dyed in-line flat polyester filaments. Background technique [0002] With the rapid development of my country's economy, the textile industry has also ushered in another era of rapid development. People's consumption on food, clothing, housing and transportation has driven the development of the textile economy. Among them, the market not only has a strong demand for the quantity of textiles, but also requires the continuous improvement of the quality of textiles, and people's demand for the use and performance of textiles is developing in the direction of diversification and high quality. The performance requirements of fabrics that people expect are often excellent optical properties; good moisture absorption and breathability; light weight, water and sweat absorption, easy to wash and quick-dry; more comfortable hand feeling; Anti-fouling effe...
