Abstract

The invention relates to a synthetic fiber production method, in particular to a device and a method for the online polynary addition production of color and functional fibers by directly spinning fused mass, which mainly solves the technical problems existed in the prior art that the flowing pressure and the speed of the fused mass can not be randomly controlled, the efficiency is lower, the production cost is higher, the technological range is narrow, and the like. The device comprises an accretion preparation device, a filtering device, a measuring device, a polynary coupler, a booster pump, a dynamic disperser, a first three-way valve, a second three-way valve, a drain valve and a numerical control device. The method comprises the following steps: respectively adding raw material of pigment and additive to the accretion preparation device and adjusting the addition by the numerical control device; enabling main fused mass to enter the polynary coupler by passing the filtering device, the measuring device and the polynary coupler to be coupled with the pigment and the additive; and enabling the coupled polynary fused mass to enter the dynamic disperser to be dispersed and finally spun.

Description

technical field [0001] The invention relates to a method for producing synthetic fibers, in particular to an equipment and method for producing colored and functional fibers with multiple additions on-line for direct spinning of melts. Background technique [0002] At present, fiber coloring in the textile industry mainly adopts first weaving, then dyeing, and then finishing and dyeing. The production of colored fabrics goes through spinning (yarn), high-temperature and high-pressure dyeing, warping and weaving, finishing, or spinning, warping and weaving, pre-dyeing treatment, high-temperature and high-pressure dyeing, and finishing. The white polyester filaments produced by conventional spinning are dyed with disperse dyes under high temperature and high pressure or in the presence of carriers, which will cause great damage to the fibers, poor color fastness, long process flow, high energy consumption and serious pollution. The production of colored fibers and functional ...
