Melt-direct spinning production system with addition of color sizing primary liquid

Abstract

The invention relates to a melt-direct spinning production system with the addition of color sizing primary liquid. The system comprises spinning manifolds arranged in a pair, a primary pipeline is arranged between the two spinning manifolds arranged in a pair and is connected with a secondary pipeline which is connected with a tertiary pipeline, and the tertiary pipeline is connected with a melt conveying pipeline. A melt-direct spinning device is arranged at the end of the melt conveying pipeline which is provided with a color sizing primary liquid adding device. The melt-direct spinning device comprises a polymerization reactor, a booster pump and a cooler which are sequentially connected. The color sizing primary liquid adding device comprises an agitator tank and a metering pump, a pressure controller and a metering controller are arranged on the metering pump respectively, and a temperature controller is arranged on the pipeline between the metering pump and the melt conveying pipeline. The melt-direct spinning production system is low in energy consumption, good in dyeing effect and high in efficiency and achieves zero release.

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.
