Production system of adding color paste stock solution by single box melt direct spinning

Abstract

The invention relates to a production system of adding color paste stock solution by single box melt direct spinning. The system comprises spinning box bodies which are arranged in pairs; a first-grade pipeline is installed between two spinning box bodies; the first-grade pipeline is connected with a second-grade pipeline; the second-grade pipeline is connected with a third-grade pipeline; the third-grade pipeline is connected with a melt transferring pipeline; a melt direct spinning device is installed at the end part of the melt transferring pipeline; the first-grade pipeline is connected with a color paste stock solution adding device; the melt direct spinning device comprises a polymerization reactor, a booster pump and a cooler which are connected sequentially; the color paste stock solution adding device comprises a stirring tank and a metering pump; the metering pump is provided with a pressure controller and a metering controller; a temperature controller is installed on the pipeline between the stirring tank and the spinning box bodies. The production system has low energy consumption, good dyeing effect, high efficiency and zero emission.

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.
