Embodiment 1

[0019] A method for dyeing cotton fabrics, comprising the steps of:

[0020] Step 1: Cotton fabric is smelted. Put the cotton fabric into water containing refining agent at room temperature. Each liter of water contains 3g of refining agent. Heat up to 90°C and keep it warm for 30 minutes. Then drain all the water and rinse with water. Cotton fabric 10min;

[0021] Step 2: Dyeing, first put the dye into the dyeing vat with the dye accelerator sodium sulfate, the temperature in the dyeing vat is 40°C, the bath ratio is 1:10, and then put the cotton fabric smelted in step 1 into the dyeing vat In the middle, after keeping warm for 10 minutes, raise the temperature of the dye solution in the dye vat to 80°C, keep warm for 50 minutes, and turn the cotton fabric 5 times during the period;

[0022] Step 3: Cool down and wash, cool down the cotton fabric dyed in step 2 to normal temperature, let go of all the dye in the dyeing vat, change to clean water and wash for 15 minutes, add ...

Abstract

The invention discloses a dyeing method of a cotton fabric. The dyeing method comprises the following steps of 1, scouring the cotton fabric; 2, dyeing, firstly, feeding a dye into a dye vat with a dyeing promoter, i.e., anhydrous sodium sulphate, wherein the temperature of the dye vat is 40 to 60 DEG C, and bath ratio in the dye vat is 1:(10 to 15), then feeding the cotton fabric scoured in the step 1 into the dye vat, after performing keeping warm preservation for 10 to 30 minutes, increasing the dye liquor temperature in the dye vat to 80 to 100 DEG C, performing keeping warm preservation for 50 to 70 minutes, and turning the cotton fabric for 5 to 7 times; 3, reducing temperature, and washing; 4, performing spinnability processing. The invention provides the dyeing method of the cotton fabric. The dyeing method is simple and relatively low in cost, contaminant is not generated, production can be performed without specific equipment, the cotton fabric produced by the method is low in light color difference, and soft and fluffy in hand feeling, and the problems of color floating, color fading, color staining, neps, color fastness and the like are solved basically.

Description

technical field [0001] The invention belongs to the field of garment processing, and in particular relates to a method for dyeing cotton fabrics. Background technique [0002] Cotton fabrics have become popular in the international market because of their good water absorption, strong air permeability, antistatic, easy decontamination, and soft texture. Nowadays, cotton sportswear is more popular among people, but most of the commercially available cotton fabrics are woven first and then knitted. Made by dyeing process. Therefore, the color is monotonous, there are few varieties of designs and colors, and the process is long. The cotton is spun into a bobbin by a cotton spinning mill, and then turned into a skein to be dyed. After dyeing, it needs to be turned into a bobbin for weaving or knitting. use. There are many repeated processes back and forth, which is time-consuming and laborious, resulting in unnecessary waste, and it is easy to cause defective products in yarn ...
