Dyeing and finishing method for acetate velvet fabric

Abstract

The invention discloses a dyeing and finishing method for an acetate velvet fabric. The method comprises the following steps: inspecting the fabric, conducting heat setting on the fabric, shearing thefabric, pre-shrinking the fabric, putting the fabric on a star frame, refining the fabric, washing the refined fabric for the first time, dyeing the fabric, washing the dyed fabric for the second time, and finishing after dyeing. Through adoption of the dyeing and finishing method, the dyeing rate of the fabric is consistent, the flatness is high, the phenomena of flower gray and dyeing defect are avoided, the dyeing effect of guaranteeing the dye fastness is achieved, the dyeing and finishing method is simple, the process and the dye are simple and easy to control, and green environmental-friendly dyeing and finishing are realized.

Description

technical field [0001] The invention relates to the field of fabric dyeing, in particular to a method for dyeing and finishing acetate velvet fabrics. Background technique [0002] After dyeing and finishing, the acetate velvet fabric has smooth, smooth, upright fluff, plump and soft hand feeling, bright color and elegant appearance. The common acetate velvet fabric is made of diacetate fiber as the suede surface and nylon fiber as the suede bottom. It has a good appearance and can be used for women's clothing and skirt materials, and is widely welcomed by consumers. [0003] The dyeing and finishing process of acetate velvet fabrics in the prior art often causes irregular fluff and defects, which affects the appearance quality of the product, and cannot make the fabric dyeing and finishing process under the condition of being completely loose and not squeezed.

Problems solved by technology

[0003] The dyeing and finishing process of acetate velvet fabrics in the prior art often causes irregular fluff and defects, which affects the appearance quality of the product, and cannot make the fabric dyeing and finishing under the condition of being completely loose and not squeezed

In the dyeing process, if the fabric is directly dyed, the required dyeing temperature of acetate fiber and polyester fiber is different, and inappropriate dyeing temperature will easily cause uneven dyeing of the fabric

The dyeing method in the prior art, the dyeing is relatively dull, which cannot meet the bright color requirements of home textile products; the dyeing process is too long, high temperature processing will lead to stiff hand feeling, and the hand feel and color brightness of the dyed fabric are not ideal

After the dyeing is completed, the fabric is usually washed with alkaline reduction, which will cause the deacetylation reaction of the acetate fiber, which will cause the disperse dye to fall off, which will cause uneven fading and white spots on the fabric, and will also reduce the fabric. breaking strength

Chinese patent CN103243590A discloses a "dyeing and finishing process of cotton / viscose and acetate fiber interwoven cloth", and specifically discloses the use of a medium-temperature one-bath method for dyeing cotton / viscose and acetate fiber interwoven cloth. However, this method is During pretreatment and dyeing, it is easy to damage the strength of acetate fiber, and the cloth surface will lose its luster. When using reactive dyes to fix the color, it is easy to dye the dye on the acetate fiber
