Problems solved by technology

[0003] At present, the two-step or three-step method of spinning, drawing and interlacing is usually used in the domestic and foreign markets. This technology and processing method has long process flow, complicated processing procedures, low production efficiency and low production capacity. , high production costs and other shortcomings, the quality of its network mixed fiber yarn products has problems such as uneven network, uneven dyeing, poor elasticity, easy shrinkage, poor wrinkle resistance and shape retention, and unstable quality between product batches. The quality requirements for the production of imitation natural fiber fabrics such as silk and plush

Abstract

The invention discloses a production technique of a super-high-speed dacron and chinlon spinning dual-component crossing composite fiber. A chinlon 6 dry slice and a dacron dry slice are input to twodifferent spinning screw extruders to heat, melt, mix, meter and filter and then enter two different spinning boxes, two metering pumps and two spinning components to form a melt body; then the melt body is extruded from two spinneret plate micropores, and cooled and cured to be two wires through a cooling device; through nozzle oiling, pre-networking, stretching and thermal shaping, the chinlon 6beam wires and Dacron beam wire can be formed and then input to a crossing compounding device to compound, roll and shape at super-high speed, thus the product is acquired. The dual-component crossing composite fiber has good wet absorption and air breathability, anti-wrinkle performance; the fiber is applicable to high-grade fabrics and cloth fabric, and is featured by short technical flow, lowproduction cost, multifunctional, high in addition value, and obvious in performance cost, and others.

Description

technical field [0001] The invention belongs to the technical field of differential chemical fibers, and relates to a composite fiber produced by interlacing elastic components and non-elastic components, in particular to a production process for super-high-speed spinning polyester nylon two-component intertwined composite fiber. Background technique [0002] The production technology and output of my country's polyester fiber industry have achieved rapid development, reaching or exceeding the international advanced level. There are bottlenecks in research and development that need to be solved urgently, especially compared with the high-tech chemical fibers and products in Japan, Europe and the United States, there is still a big gap, and we are still facing huge challenges. Therefore, how to solve the problems of high-performance, functional, and comfortable development, and accelerate the processing technology of unconventional high-value-added products such as super-simul...
