Embodiment 1

[0026] Gray fabric: Regenerated fiber containing naphthol dye pretreatment agent and bleached cotton fiber are blended at a ratio of 50:50.

[0027] Dyeing process: first pre-dye the gray cloth, and then add red naphthol dye to the bath solution for dyeing, dye the regenerated fiber containing naphthol dye pretreatment agent in the gray cloth red, and the cotton fiber is undyed white , the gray cloth shows red and white mixed colors, and then the dyed cloth is post-treated, such as color fixing, washing, etc., and finally the post-treated cloth is not dried and shaped to get the finished product.

Embodiment 2

[0029] Gray fabric: Regenerated fiber containing naphthol dye pretreatment agent and bleached cotton fiber are blended at a ratio of 50:50.

[0030] Dyeing process: Compared with Example 1, the main difference is that red naphthol dye is added for dyeing, and yellow direct dye is added for dyeing after 30 minutes, and the gray cloth presents red and yellow mixed colors after dyeing.

Embodiment 3

[0032] Gray fabric: Regenerated fiber containing naphthol dye pretreatment agent, cationic regenerated fiber and bleached cotton fiber are blended according to the ratio of 30:20:50.

[0033] Dyeing process: first pre-dye the gray cloth, then add red naphthol dye to the bath solution for dyeing, add navy blue cationic dye for dyeing after 30 minutes, and dye the regenerated fiber containing naphthol dye pretreatment agent in the gray cloth Red, cationic regenerated fiber is dyed navy blue, while cotton fiber is undyed white, the gray cloth shows a mixed color of red, navy blue and white, and then the dyed cloth is post-treated, such as color fixing , washing and other treatments, and finally the post-treatment is not dried and shaped to get the finished product.

Abstract

The invention discloses a blended color dyeing method of a fabric, which comprises the following specific steps of: (100) blending: blending a first fiber and a second fiber according to a certain ratio to obtain a gray fabric, wherein the first fiber comprises a regenerated fiber containing a naphthol dye pretreating agent, and the second fiber comprises bleached cotton fiber; (200) pretreatment: treating the gray fabric before dyeing; (300) dyeing: firstly adding a naphthol dye into the solution to dye; (400) after-treatment: after-treating the dyed fabric; and (500) drying and forming: drying and forming the after-treated fabric to obtain the finished product. With the blended color dyeing method of a fabric, the fabric can have various colors, and the fabric has excellent fullness and fastness.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a method for mixed-color printing and dyeing of fabrics. Background technique [0002] With the improvement of people's living standards, people's requirements for textiles are getting higher and higher. A large number of fabrics blended with fibers of different properties have emerged on the market, so that the fabrics have the characteristics of different fibers at the same time. Commonly used are polyester-cotton blended fabrics, which are woven by blending polyester and cotton. On the one hand, they have the characteristics of high strength and good wrinkle resistance of polyester fibers, and at the same time, they have the advantages of good hygroscopicity and comfortable wearing of cotton. [0003] The mixed-color frosted fabrics on the market mainly use different colors of fibers to blend to form mixed-color yarns, and then weave into mixed-color fabrics. When ...
