Embodiment 1

[0019] A dyeing process for microfiber fabrics involved in this embodiment comprises the following steps: (1) pre-dyeing treatment, (2) pulse plasma treatment, (3) dyeing, (4) soaping, (5) color fixing.

[0020] Step (1) pre-dyeing treatment is to immerse the polyester-nylon composite superfine fabric in the pre-dyeing treatment solution at room temperature, raise the temperature to 90°C at a heating rate of 1°C / min, and keep it warm for 45 minutes.

[0021] Include degreaser, penetrating agent, anti-wrinkle agent in bath, water softener, refining agent in the dyeing pretreatment liquid; Added water softener makes the hardness of water be 7; The content of described degreaser is 2g / L, The content of penetrant is 2g / L, the content of anti-wrinkle agent in the bath is 1.5g / L, and the content of refining agent is 10g / L.

[0022] (2) Pulse plasma treatment: After drying the pre-treated polyester / nylon composite ultra-fine fabric, pulse plasma treatment is performed on the front an...

Embodiment 2

[0031] A dyeing process for microfiber fabrics involved in this embodiment comprises the following steps: (1) pre-dyeing treatment, (2) pulse plasma treatment, (3) dyeing, (4) soaping, (5) color fixing.

Abstract

The invention discloses a dyeing process for superfine fiber fabrics, which includes the following steps: (1) pre-dyeing treatment, (2) pulse plasma treatment, (3) dyeing, (4) soaping, and (5) fixation.According to the dyeing process for superfine fiber fabrics of the invention, when dyeing polyester and nylon superfine fiber fabrics, the pulse plasma treatment is used first, then dyeing is performed, and phenylacrylate, a superfiber promoter LB, a high-temperature high-pressure leveling agent, a shade stabilizer and other auxiliary agents are added during dyeing, so that the dyed polyester and nylon have good homochromatism; moreover, a permanent wet rubbing fastness improver is used during fixation, so that the color fastness after dyeing is improved.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing, in particular to a superfine fiber fabric dyeing process. Background technique [0002] Due to the low denier of microfiber, it causes changes in fabric performance and dyeing performance, and the dyeing technology must be improved. Polyester-nylon composite microfiber fabric is a large category of superfine fabrics, often made of ordinary polyester fibers for warp yarns and polyester-nylon composite superfine fibers for weft yarns. Since the composite fiber contains polyester and nylon dual components, although their supramolecular structures are basically similar, their polymerized monomers are different. Therefore, the dyeing changes caused by the different characteristics of polyester and nylon fibers should be considered during the dyeing process. Polyester fibers can only be dyed with disperse dyes, and because the fiber structure is tight and hydrophilic is very low, that is, the po...
