Problems solved by technology

[0004] Although the dyeing process of nylon-cotton blended fabrics is basically mature, due to the different dyeing properties of nylon and cotton components, enterprises often have color flashing problems caused by inconsistent hues during processing, and product quality is unstable. The reactive two-bath dyeing process is relatively complicated and consumes a lot of energy, while the air cylinder dyeing has higher requirements on dyeing materials, and the processor needs to have rich practical experience in order to obtain better product quality

Embodiment 1

[0063] Embodiment 1: middle temperature type reactive dye dyeing

[0064] 1.1 Orthogonal test

[0065] In order to systematically study the effects of various factors on the coloring of nylon and cotton fabrics during the one-bath dyeing of reactive dyes, the orthogonal design method was used to study the mixed samples of nylon and cotton according to the dyeing temperature from low to high. The results are shown in Table 3- 5. The medium-temperature reactive dyes used in the following experiments are reactive BES red (supplied by Shangyu Yide Chemical Co., Ltd.).

Abstract

The invention relates to a brocade cotton fabric short-process dyeing method, and belongs to the technical field of printing and dyeing in the textile manufacturing industry. The method includes subjecting brocade cotton fabric to pretreatment to remove oil stain and impurities and to improve handfeel and gloss; adding an active dye into an air flow cylinder to prepare into a dyeing solution; dyeing by adoption of a one-bath two-step method that includes acid dyeing and alkaline fixation; and after the dyeing step is finished, washing, soaping and airing to obtain a finished product. The method has advantages of uniform dyeing, good homochromatism, and the like when being used for air flow cylinder dyeing of the brocade cotton fabric such as brocade cotton intertexture.

Description

technical field [0001] The invention relates to a short-process dyeing method for nylon and cotton fabrics, belonging to the technical field of printing and dyeing in the textile manufacturing industry. Background technique [0002] With the improvement of people's living standards, single-component fiber fabrics with single performance have been gradually replaced by two-component or multi-component fiber fabrics. Nylon fiber has good elasticity, high strength, light weight and wear resistance, and good hygroscopicity; cotton fiber is soft to the touch, has good moisture absorption and air permeability, but is easy to wrinkle. Nylon / cotton interwoven fabrics have both the advantages of the two fibers but are complementary to each other. After finishing such as sanding and coating, it has excellent wearability and is widely used in industry, civil and national defense. With the development in recent years, the share of nylon and cotton fabrics in the fabric market is increa...
