Novel straight-spinning production system for melt added with color paste stock solution

Abstract

The invention relates to a novel straight-spinning production system for melt added with a color paste stock solution. The novel straight-spinning production system for the melt added with the color paste stock solution comprises a polymerization reaction device, a booster pump, a melt cooler and spinning manifolds which are arranged in a pairing mode, wherein a first spinning manifold is connected to a first metering pump, a first spinning component, a first spinning cooler, a first oil applying system, a first pre wire stitching machine, a first drafting molding device, a first main wire stitching machine, a first winding molding device, a first testing grading device and a first packaging device in sequence, a second spinning manifold is connected to a second metering pump, a second spinning component, a second spinning cooler, a second oil applying system, a second pre wire stitching machine, a second drafting molding device, a second main wire stitching machine, a second winding molding device, a second testing grading device and a second packaging device in sequence, color paste stock solution adding systems are arranged between the spinning manifolds which are arranged in the pairing mode and melt coolers, and the color paste stock solution adding systems comprise color paste stock solution stirring pots and third metering pumps. According to the novel straight-spinning production system for the melt added with the color paste stock solution, the energy consumption is low, the dyeing effect is good, the efficiency is high, and zero emission is achieved.

Description

technical field [0001] The invention relates to a spinning production system, in particular to a spinning production system with color paste added. Background technique [0002] Since the 21st century, my country's polyester industry has developed rapidly. In 2000, the output of polyester fiber was 5.1 million tons, by 2009 it had reached 22 million tons, and in 2010 it had reached 25.1 million tons. An increase of 20 million tons in 10 years, with an average annual growth rate of more than 15%. Its scope of application has also expanded rapidly, involving clothing, decoration, home textiles, industrial textiles, industrial engineering and other aspects of the national economy and people's livelihood. The latest data show that more than 80% of chemical fiber products need to be printed and dyed, and the sewage generated by printing and dyeing reaches 5 billion tons every year. At the same time, as a textile material, polyester fiber also has the following disadvantages: p...

Problems solved by technology

At the same time, as a textile material, polyester fiber also has the following disadvantages: poor dyeability, low color fastness, poor weather resistance, etc.

Conventional polyester dyeing is generally carried out under high temperature and high pressure. It is completed through multiple processes such as desizing and dyeing with dyes. There are problems such as high energy consumption, low efficiency, poor color fastness and weather resistance of dyed fibers, high dyeing costs, and serious pollution.
