Abstract

The invention discloses a production process and process equipment for polyester crimped yarn, wherein the production process is as follows: drying the copolyester chips, putting the dried copolyester chips into an extrusion device, heating and melting the copolyester chips to obtain the copolyester chips melt; pressing the copolyester chips melt into a spinning beam, measuring the flow by a measuring pump and flowing into the spinning components, and then enabling the copolyester chips melt to pass through a spinneret plate of the spinning components, so as to obtain copolyester chips melt trickle flow, and then cooling and solidifying the copolyester chips melt trickle flow through a cooling and solidifying device to obtain the copolyester yarn; treating the copolyester yarn successively by the steps of applying oil via a lubricating nipple, pre-network and heat-setting, and then winding and forming. The process equipment comprises a drying device, an extrusion device, a spinning beam, a cooling and solidifying device and a winding and forming device which are connected in sequence according to the order. The polyester crimped yarn produced by the production process provided by the invention has the characteristics of silk-like sheen and feel, fabric bright sense, elegant and soft silk light perception; the polyester crimped yarn not only has excellent optical properties, but also realizes good air permeability and has a super bright glittery effect.

Description

technical field [0001] The invention relates to the field of synthetic fibers, in particular to a production process and process equipment for polyester crimped yarn. Background technique [0002] With the continuous development of my country's national economy and the continuous improvement of people's living standards, people's demand for various differentiated fibers with excellent performance must be further strengthened. However, most of the polyester fibers produced in my country are conventional varieties. The competition in the chemical fiber industry is becoming increasingly fierce, and the ordinary circular cross-section polyester fiber can no longer adapt to market changes and people's requirements. [0003] In response to market demand and competition at home and abroad, many enterprises have continuously developed new varieties of polyester, and are developing towards high-performance and functional fibers. Spinning ultra-bright special-shaped polyester crimped y...
