Embodiment approach

[0066] As a preferred embodiment of the present invention, described novel polyester imitation suede fabric dyeing process, comprises the following steps:

[0067] (a) Pretreat the polyester suede fabric by using double-dielectric barrier subglow discharge plasma treatment equipment; wherein, the treatment current intensity is 1-5A, and the treatment time is 5-60min;

[0068] (b) placing the pretreated polyester suede fabric in a dye bath for dyeing, reduction cleaning, washing, and drying;

[0069] In the dye bath, the dye concentration is 4-10% owf, the bath ratio is 1:(3-100), the concentration of chitosan acetic acid solution is 5-20g / L, and the concentration of polyethylene glycol is 8-12% owf .

[0070] On the basis of ensuring the mechanical properties of the fabric, optimizing the parameters of the double-dielectric barrier sub-glow discharge plasma treatment and improving the processing technology of the ultra-fine polyester suede fabric can reduce the amount of alka...

Embodiment 1

[0075] A kind of novel polyester imitation suede fabric dyeing process that present embodiment provides, comprises the following steps:

[0076] (a) Turn on the power supply of the dual-dielectric barrier sub-glow discharge plasma treatment equipment, preheat for 30 minutes, set the treatment current intensity to 1A, and put a 5cm×25cm polyester suede fabric strip into the built-in cloth of the plasma treatment equipment. Fix it in the gap of the strip, carry out pretreatment, adjust the rotating speed to be 10m / min (the distance of running one circle is 10m), and the processing time is 60min;

[0077] (b) placing the pretreated polyester suede-like fabric in a dye bath for dyeing;

[0078] Concrete, prepare dyeing bath, wherein dyestuff (disperse red EDT-R) concentration is 4% owf, and bath ratio is 1:3, and the concentration of chitosan acetic acid solution is 5g / L (chitosan acetic acid solution passes chitosan Sugar is dissolved in 2% acetic acid and prepared), and the con...

Embodiment 2

[0081] A kind of novel polyester imitation suede fabric dyeing process that present embodiment provides, comprises the following steps:

[0082] (a) Turn on the power supply of the dual-dielectric barrier subglow discharge plasma treatment equipment, preheat for 30 minutes, set the treatment current intensity to 3A, and put a 5cm×25cm polyester suede fabric strip into the built-in cloth of the plasma treatment equipment. Fix in the strip gap, carry out pretreatment, adjust the rotating speed to be 10m / min (the running distance is 10m), and the processing time is 30min;

[0083] (b) placing the pretreated polyester suede-like fabric in a dye bath for dyeing;

[0084]Concrete, prepare dyeing bath, wherein dyestuff (disperse red EDT-R) concentration is 6% owf, bath ratio is 1:30, and the concentration of chitosan acetic acid solution is 10g / L (chitosan acetic acid solution is passed through chitosan Sugar is dissolved in 2% acetic acid and prepared), and the concentration of pol...

Abstract

The invention provides a novel polyester suede fabric dyeing process and an application thereof, and relates to the technical field of textile printing and dyeing. According to the novel polyester suede fabric dyeing process, a polyester suede fabric is pretreated by a subglow discharge plasma treatment technology, and then the polyester suede fabric is subjected to dyeing processing by a method of compounding a non-ionic high-molecular polymer and a cationic high-molecular polymer; the dyeing process can significantly improve the deep dyeing property, levelling property and color fastness ofthe fabric on the basis of no influence, even improving effect, on physical and mechanical properties of the fabric; through detection, the dyeing rate of the polyester suede fabric after the dyeing process treatment can reach 80-98%, and the technical problems of poor levelling property, deep dyeing property and color fastness in the dyeing processing process of a polyester suede fabric are solved. The invention also provides the application of the novel polyester suede fabric dyeing process, and provides the basis for industrialized production of the polyester suede fabric.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing process and application of a novel polyester imitation suede fabric. Background technique [0002] Polyester imitation suede fabric is one of the new polyester fabrics. It uses fine denier or superfine denier polyester fiber as raw material. After special finishing and processing, it forms a polyester suede fabric with fine and short fluff on the fabric base fabric. Because of its soft texture, fluff It is favored by consumers for its advantages of fineness, plumpness, elasticity, rich hand feeling, firmness and durability, and good wear resistance. [0003] Although polyester suede fabric has excellent wearability, in the dyeing process, the dyeing of polyester suede fabric is much more difficult than ordinary polyester fabric. This is mainly due to the large specific surface area of ​​the microfiber itself on the polyester suede fabric, and there a...
