Technical Field

the invention belongs to the field of dyeing and finishing, and particularly relates to a one-bath dyeing method for wool-covered polyester single jersey.

Background

The multi-component fiber textile is a garment fabric or a decorative material which is prepared by mixing and using fibers with different types, physical properties, functions, forms and the like and shows functions, styles and fabric textures which a single material does not have. Multicomponent fabrics have many advantages not found in monocomponent fabrics, such as: each fiber makes up for the weakness in physical properties, and the performance of the textile is improved; the durability of the textile is improved; the texture and the appearance of the textile are improved; defects generated in spinning, weaving, printing and dyeing of part of single fibers are reduced; the cost of partial textile is reduced, and the like.

The wool-covered polyester undershirt cloth is different from common polyester-wool undershirt cloth, and the product has pure color and luster, stiff and smooth style, strong full-wool feeling and better extensibility. The dyed final finished product can be made into sports and leisure fashionable clothes, and is popular with consumers.

At present, more researches on dyeing of wool-polyester fabrics are available, but the researches on dyeing of wool-cap-polyester single jersey are still less, and the market application of the wool-cap-polyester single jersey is limited.

Disclosure of Invention

The invention aims to solve the technical problem of providing a one-bath dyeing method of wool-cap polyester undershirt cloth, and the method solves the technical problem that the wool-cap polyester undershirt cloth is difficult to dye.

The invention provides a one-bath dyeing method of wool-cap polyester single jersey, which comprises the following steps:

(1) Pretreating the wool-covered polyester single jersey: adding degreaser 1-2g/L and smoothing agent 1-2g/L into a dye vat, stirring uniformly, adding into the dye vat, heating to 70-75 deg.C, and keeping the temperature for 20-30 min;

(2) adding a dyeing auxiliary agent into a dye vat, uniformly stirring, and then adding into a dyeing machine; injecting the reactive dye for wool into a dye vat, after running for 5-15min, heating to 50-55 ℃ at the speed of 0.5-1 ℃/min, adding the disperse cationic dye, after running for 5-15min, heating to 100-110 ℃ at the speed of 0.7-1 ℃/min, preserving heat for 30-60min, cooling to 80-85 ℃ at the speed of 1-2/min, and discharging liquor; the dyeing auxiliary agent comprises the following components: albugo B1.0-2.0% owf, mirabilite 3-5g/L, glacial acetic acid 0.5-2g/L, Ganglegao P-EW 1.0-2.0% owf;

(3) cleaning the dyed wool-covered polyester single jersey: supplying water, heating to 50-60 deg.C, maintaining the temperature for 10-20min, and discharging liquid; feeding water, injecting cleaning agent RPD into dyeing machine at 1-3g/L, heating to 70-75 deg.C at 2-3 deg.C/min, maintaining for 20-30min, draining, feeding water, washing with water, and draining.

The deoiling agent in the step (1) is TF-115B; the smoothing agent in the bath was BT 44.

In the steps (1) and (2), industrial soft water is injected into the dye vat in advance according to the bath ratio of 1: 12.

the wool reactive dye in the step (2) is a Clausol series dye.

The disperse cationic dye in the step (2) is KAYACRYL series dye.

And after cleaning, performing after-treatment on the wool-covered polyester single jersey.

According to the method, the leveling agents in the market are screened, and the albizzia B with a good leveling effect is selected as the wool leveling agent during dyeing, so that the dyeing risk is reduced. The color tone is high, the P-EW can reduce the dyeing temperature of the terylene, increase the color yield and save cost. The cleaning agent RPD is a fastness improver for cleaning after dyeing, and can effectively reduce the flooding and staining of the cloth surface.

Advantageous effects

The dyeing method is simple, the types of the auxiliary agents required in the process are few, the total process time is short, and the energy conservation and emission reduction are facilitated; the dyeing condition is mild, the damage to wool is small, the warm-keeping, comfortable and elegant characteristics of the wool-covered polyester single jersey are kept, meanwhile, the fabric has high washing fastness, the quality of the fabric is improved, and the application prospect is good.
