Problems solved by technology

At present, the colored fibers in colored spinning yarns on the market are mostly cotton loose fibers dyed with K-type or KN-type reactive dyes. The color is bright, the color spectrum is complete, and various styles can be formed. After mercerizing, the color will fade seriously and the color will become dull. After processing, color supplementation must be carried out, which increases the loss of manpower, material resources, and energy, and the production efficiency is low. In addition, the colored fibers in colored spinning are dyed with high-temperature dyes. S-triazine structure reactive dye, capable of strong alkali mercerizing, but poor discharge performance
To sum up, the disadvantages of color spinning not being able to pull out alkali and being pullable but not alkali resistant have seriously hindered the further development and application of color spinning

Abstract

The invention relates to a processing method of alkali-resistant dischargeable mercerized colored spun yarn, belonging to the field of spinning. The method comprises the following steps of: a, dyeing sliver, wherein the sliver is dyed with the required color by use of a dischargeable reactive dye containing two active groups of monochloro-sym-triazine and vinyl sulfone; b, spinning, wherein the dyed sliver obtained by the step a is spun with the true-color or dyed sliver according to a proportion; c, singeing and reeling the colored spun yarn obtained by the step b; and d, mercerizing the colored spun yarn obtained by the step c. The processing method provided by the invention originates the alkali-resistant dischargeable mercerized colored spun yarn, not only maintains the original features of the colored spun yarn, but also enables the colored spun yarn to be resistant to strong alkali mercerizing; the colored fabric has the alkali-resistant dischargeable performance; and the shortcoming that the common colored spun yarn is alkali-resistant but not dischargeable or is dischargeable but not alkali-resistant is overcome.

Description

technical field [0001] The invention relates to a processing method of colored spun yarn in the technical field of textiles, in particular to a processing method of colored spun yarn with discharge dyeability and strong alkali mercerizing resistance. Background technique [0002] Color spun yarn is generally a yarn made by mixing two or more fibers of different colors. The fabric woven from color spun yarn has a hazy and natural style effect and is very popular among consumers. At present, the colored fibers in colored spinning yarns on the market are mostly cotton loose fibers dyed with K-type or KN-type reactive dyes. The color is bright, the color spectrum is complete, and various styles can be formed. After mercerizing, the color fades seriously, and the color is dull. After processing, color supplementation must be carried out, which increases the loss of manpower, material resources, and energy, and the production efficiency is low. In addition, the colored fibers in c...
