Problems solved by technology

[0005] 1) The load capacity of each bobbin is limited, between 0.8-1.0kg, and the dyeing output of the bobbin needs to be improved;
[0006] 2) When polyester superfine fiber is dyed at high temperature and high pressure, the fiber will be shrunk, and the density of the yarn will increase after shrinkage, resulting in insufficient penetration of the dye solution, resulting in poor inner and outer layers of colored flowers, and the dyeing quality of the bobbin needs to be improved

Embodiment 1

[0027] A kind of cheese dyeing method of polyester microfiber with low bath ratio, the dyeing process comprises the following steps,

[0028] High-temperature pre-shrinking process: put the polyester superfine fiber bobbin of DTY 288F 150D into the high-temperature pre-shrinking processor, start from room temperature, raise the temperature to 85°C at a rate of 3°C / min, and continue to heat up at a rate of 1°C / min. Speed ​​up to 110°C, continue to heat up to 125-130°C at a rate of 1.8°C / min, wet for 3.5 hours, and cool down to room temperature naturally;

[0029] Pre-treatment process: wind the polyester superfine fiber after high-temperature preshrinking treatment from the bobbin, and increase the weight of the polyester fiber carried by each bobbin from 0.8-1.0kg to 1.3kg, and determine the constant bath ratio of 1:3, using The cheese is dyed in the dyeing machine, and at the same time, additives such as hydrogen peroxide, alkali-removing agent, penetrant, and stabilizer are ...

Abstract

The invention relates to a low-bath-ratio bobbin dyeing method of ultrafine terylene fibers. The method comprises a high-temperature pre-shrinking treating process, a pretreating process, a dyeing process and a post-treating process. According to the method, the temperature increasing rate, the temperature degree and the temperature maintaining time are set in the high-temperature pre-shrinking treating process, so that the weight of the ultrafine terylene fibers supported by each spool can be effectively increased, and the yield is increased; and meanwhile, the density, pressure difference and other problems in the ultrafine terylene fiber dyeing technology are solved by the low-bath-ratio dyeing method; and the technical requirement of dyeing at ultralow bath ratio of 1: 3 can be met.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a low bath ratio dyeing method for cheeses of polyester superfine fibers. Background technique [0002] Environmentally-friendly production has now become a concept advocated by all kinds of companies around the world. "Ultra-low bath ratio" yarn dyeing machines have begun to conquer consumers one after another by virtue of their many advantages in energy saving and environmental protection. Liquor ratio is an important index in the dyeing process, and the size of liquor ratio directly reflects the key indicators of water, electricity, steam and other energy consumption of dyeing equipment and the level of pollutant discharge. The liquor ratio of yarn dyeing is divided into three categories, above 1:8 is a large liquor ratio, 1:4 is a low liquor ratio, and below 1:4 is an ultra-low liquor ratio. The "ultra-low bath ratio" technology creates the possibility for printing and dyeing factori...
