Problems solved by technology
[0002] Due to the high elasticity and easy curling of polyester knitted fabrics, rope overflow dyeing machines or air-flow O-shaped cylinders are currently used in the market for dyeing, resulting in a large amount of sewage discharge, waste of dyes, high labor intensity, and many people. The color difference, cloth scratches and other defective products, China currently has millions of dye vats, causing a lot of pollution and waste

Embodiment 1
[0031] A polyester knitting dyeing process, which is dyed by equipment consisting of a low-tension degreasing machine with a steam box, a loose dryer and a multi-layer tenter pad dyeing machine, which includes the following steps:
[0032] 1. Degreasing treatment: through the low tension degreasing machine, including:
[0033] 1.1 Open-width or roll-packed cloth, centered by opening width;
[0034] 1.2 Pump the degreasing agent into the liquid tank through the automatic pump;
[0035] 1.3 The cloth enters the liquid tank through the open roller, dips in the degreaser, enters the double rubber roller (outsourced with butyl rubber) through the open roller, and is evenly rolled and squeezed before output;
[0036] 1.4 Enter the steam box after squeezing the water, and the cloth is in a relaxed state, and the degreasing agent continues to have an effect on the cloth;
[0037] 1.5 Enter the four low-tension drum washing unit, and wash the cloth through four water rolling at the s...

Abstract
The invention belongs to the technical field of cloth dyeing and relates to a polyester knitting and dyeing process. The polyester knitting and dyeing process includes the steps of firstly, using a low-tension degreasing machine to degrease cloth; secondly, allowing the degreased cloth to enter a loose type drying machine, drying through three tracks, and dropping and discharging the cloth; thirdly, dyeing the cloth free of grease after processing in a 'multilayer tentering padding mangle'. The polyester knitting and dyeing process has the advantages that the problem that open width cannot be processed during knitting processing due to hems or excessively large tension, and a dye vat can be replaced; the polyester knitting and dyeing process is energy-saving, low in emission, low in energy consumption, capable of increasing product quality, capable of avoiding pigment waste, and the like; the problem that open width dyeing cannot be performed on knitted fabric due to the elastic hems is solved, the cloth is allowed to be pulled by a needle plate pulled by a chain under effective cloth edge control, and the advantages of hot-melt-method disperse dye polyester knitting under open width dyeing are obtained.
Description
technical field [0001] The invention belongs to the technical field of cloth dyeing and relates to a polyester knitting dyeing process. Background technique [0002] Due to the high elasticity and easy curling of polyester knitted fabrics, rope overflow dyeing machines or air-flow O-shaped cylinders are currently used in the market for dyeing, resulting in a large amount of sewage discharge, waste of dyes, high labor intensity, and many people. There are several million dye vats in China, causing a lot of pollution and waste. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and to provide a polyester knitting dyeing process, which is carried out through the equipment consisting of a low-tension oil remover with a steam box, a loose dryer and a multi-layer tenter pad dyeing machine. Dyeing, wherein, comprises the following steps: [0004] 1. Degreasing treatment: through the low tension degreasing mach...
