A sample color dithering method of polyester/cellulose fiber blended fabric

Abstract

The invention relates to a method for dithering a sample of a polyester / cellulose fiber blended fabric, comprising the following steps: (1) treating a customer sample with acid, and preliminarily determining the dyeing prescription and process conditions of the polyester part in the blended fabric; (2) prior Process the blended fabric and dye polyester, wash and dry; (3) process the dyed blended fabric to dissolve the cellulose fiber, and compare the color difference until the polyester part is dithered successfully, and determine the dyeing prescription and process conditions for the polyester part; (4) Take several pieces of blended fabrics after pretreatment, dye polyester first according to the dyeing prescription and process conditions of the polyester part determined in (3), and then dye cellulose fibers; The dyeing prescription and process conditions of the plain fiber part; the color difference of the invention is small, the time consumption is short, and the problem of difficult and slow color dithering of small samples that occurs in actual production is effectively solved, and the success rate of duplicate samples is almost 100%; It is very helpful for the whole professional students to learn the dithering of polyester / cellulose fiber blended fabric samples.

Description

Technical field [0001] The present invention relates to a fabric dyeing technique. Background technique [0002] Common polyester / cellulose fiber mixed textile has polyester cotton mixed textile, polyester adhesive mixed textile, polyester Tiansi mixed textile, polyester modal mixed textile, etc., polyester and cellulose fiber optic strength complementary, woven fabric has both polyester style Advantages and the strengths of cellulose fiber fabrics. It is not easy to wrinkle, good, easy to washable, strong, smooth, quick dry, wear resistant, anti-static properties, good hygroscopicity, gas permeability, and cheap price. In order to meet the needs of different consumption levels, the varieties have developed a variety of polyester fibers from different ratios. [0003] Customer samples are polyester / cellulose fiber mixed fabrics, and small samples are generally in the first polyester part. After the water is washed, they are similar to customers, with the experience subjective...

Problems solved by technology

This not only takes a long time, but also the color matching effect is not good. Often, the small sample color dithering is very successful, but the duplicate sample is not successful, and the actual large-scale production sample often has a large color difference with the customer's sample, and it is difficult to correct it in time, affecting the entire process. Progress, delayed delivery time, affecting the completion of orders on time, causing serious economic losses to the enterprise

For beginners of small sample color dithering, because they have no production experience and do not have a thorough grasp of the properties and uses of dyeing materials, it is difficult to learn how to dye flat polyester fiber and cellulose in a short time by using the existing small sample color dithering method. Fiber, inevitably causing long-term confusion

[0004] Moreover, polyester and cellulose fiber blended fabrics sometimes require only one fiber to be dyed alone in order to pursue a certain style, leaving the other fiber blank (usually cellulose fiber blank). The color dithering of the small sample seems to be successful, but when the large machine is dyed, there will be a large color difference, either dark or light, which is difficult to correct quickly, resulting in a large number of the above problems, and it is difficult to achieve one-time additional by stripping or adding materials.
