Problems solved by technology

[0003] When traditional cotton and silk blended fabrics are dyed with some direct dyes, the silk fibers are often dyed darker or the cotton fibers are dyed darker. At the same time, the use of basic dyes will cause color differences
Sometimes although the shade of the color is the same, there are differences in the shade, which needs to be corrected in the subsequent process

Embodiment 1

[0014] (1) Using silk fiber yarns as warp yarns and cotton fiber yarns as weft yarns, the warp yarns and weft yarns are interwoven into cotton and silk blended fabrics, the count of the silk fiber yarns is 40, and the cotton fiber yarn counts are 50 sticks;

[0015] (2) Add reactive dyes, sodium sulfate and sodium bicarbonate to a water bath filled with water and stir evenly, then add cotton and silk blended fabric and dye for 1 hour, add sodium hydroxide to the water bath to adjust the pH The value is 8, and then adding a color-fixing agent to obtain a dyed cotton and silk blended fabric.

Embodiment 2

[0017] (1) Using silk fiber yarns as warp yarns and cotton fiber yarns as weft yarns, the warp yarns and weft yarns are interwoven into cotton and silk blended fabrics, the count of the silk fiber yarns is 45, and the cotton fiber yarn counts are 55 sticks;

[0018] (2) Add reactive dyes, sodium sulfate and sodium bicarbonate to a water bath filled with water and stir evenly, then add cotton and silk blended fabric and dye for 1 hour, add sodium hydroxide to the water bath to adjust the pH The value is 9, and then adding a color-fixing agent to obtain a dyed cotton and silk blended fabric.

Embodiment 3

[0020] (1) Using silk fiber yarn as warp yarn and cotton fiber yarn as weft yarn, the warp yarn and weft yarn are interwoven into a cotton and silk blended fabric, the count of the silk fiber yarn is 50, and the cotton fiber yarn count is 60 sticks;

[0021] (2) Add reactive dyes, sodium sulfate and sodium bicarbonate to a water bath filled with water and stir evenly, then add cotton and silk blended fabric and dye for 0.5 hours, add potassium hydroxide to the water bath to adjust pH The value is 10, then adding a color fixing agent to obtain a dyed cotton and silk blended fabric.

[0022] In the blended dyeing method of cotton and silk fabric disclosed by the invention, dyeing ensures good same-color property and long-lasting color adhesion, and sodium sulfate ensures that dye can be dyed on cotton fiber. , can be widely applied.

Abstract

The invention discloses a blend dyeing method of a cotton-real-silk fabric. The blend dyeing method comprises the following steps: based on adopting real-silk fiber yarns as warp yarns and adopting cotton fiber yarns as weft yarns, interleaving the warps and the wefts to obtain a cotton-real-silk blended fabric; adding reactive dye, sodium sulfate and sodium bicarbonate to a water bath with water; uniformly stirring; adding the cotton-real-silk blended fabric; dyeing for a certain time; adding alkali to the water bath to adjust the pH (Potential Of Hydrogen) to 8 to 10; and adding a dye-fixing agent to obtain the dyed cotton-real-silk blended fabric. According to the mode mentioned above, the blend dyeing method of the cotton-real-silk fabric, provided by the invention, has the advantages that high homochromatism is ensured by dyeing through the dye, the color can be attached for a long time, and the dye can be applied to the cotton fibers due to the sodium sulfate; the adopted method is few in processes and convenient in operation; the dyeing quality is effectively improved; and the method can be massively popularized and applied.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for blending and dyeing cotton and silk fabrics. Background technique [0002] Cotton fabric is a natural fiber. Cotton fabric has excellent warmth retention, antistatic properties, alkali resistance and hygroscopicity. To improve the feel and performance of fabrics, silk fibers can be added to them. Silk is the softest and thinnest natural fiber in nature. Silk is mainly composed of animal protein, rich in a variety of essential amino acids, and has a strong affinity and health care effect on human skin. Cotton fiber is mainly added with silk fiber It can improve the fabric properties and reduce the price of the whole blended fabric. [0003] When traditional cotton and silk blended fabrics are dyed with some direct dyes, either the silk fibers are dyed darker or the cotton fibers are dyed darker, and the use of basic dyes at the same time will cause color differences. ...
