Problems solved by technology

[0004] There are many types of fibers in blended fabrics, and the water absorption of each fiber has a certain difference, resulting in a certain difference in dyeing speed. When dyeing, uneven dyeing is prone to occur. For example, the patent No. CN201611180583.6 published " A Dyeing Process for Polyester Blended Fabrics" mentioned that polyester contains certain hydrophobic fibers, resulting in worse dyeing uniformity and speed. In the prior art, salts are generally added to assist dyeing, which makes wastewater treatment more difficult.

Embodiment 1

[0040] see figure 1 , a clean dyeing process for blended textiles, on the basis of existing technologies, such as figure 2, so that the textile fabric is dyed in rolls on the ball net, under the action of the dyeing liquid, the ball net overflows gas, interspersed between the textile fabrics and overflows upwards, speeding up the diffusion speed of the dyeing liquid near the textile fabric into the cloth, and then As the soaking time prolongs, the externally moving floating ball 4 in the ball net overflows and floats up, driving the textile fabric to move slightly during the upfloating process, further speeding up the dyeing speed, and then sprinkles micro-solid powder into the dyeing pool to make the dyeing liquid appear viscous. Thickness, reducing the fluidity of the dyeing solution, and effectively locking the dye molecules on the textile fabric, and then standing for 0.5-2h, assisting the attachment of the dyeing molecules on the textile fabric, compared with Figure 10...

Embodiment 2

[0046] like Figure 8 , the textile fabric is pretreated before rolling, and the pretreatment includes the following steps:

[0047] First, spray water mist on the surface of the textile fabric to make it wet, and then spray hydrophilic salt powder on the surface, so that the hydrophilic salt powder forms a layer of color-attracting layer on the surface. The hydrophilic salt powder is mixed with chloride Sodium starch powder, and the volume ratio of sodium chloride to starch powder is 1:2-5. Sodium chloride can effectively assist dyeing molecules in coloring textile fabrics, and effectively alleviate the dyeing of blended fabrics due to the presence of polyester. It leads to the problem of slow coloring and poor effect. In addition, through the setting of the color-attracting layer, due to the rolled fabric, the fabrics form a barrier between each other. After the color layer is dissolved in water, such as Figure 9 , so that the fluidity of the dyeing solution near the fabri...

Abstract

The invention discloses a clean dyeing process for blended textiles, which belongs to the field of dyeing technology. The cloth is dyed in a roll shape through the setting of the ball net. The floating ball can produce a certain impact on the fabric for a long time, making it move, driving the dye molecules near it to move into the fabric, and speeding up the dyeing efficiency; combined with the sprinkled micro-solid powder, the dyeing solution becomes viscous shape, reduce the fluidity of the dyeing solution, and then effectively lock the attached dye molecules on the textile fabric, making it difficult to spread outward, assisting the attachment of dye molecules on the textile fabric, making the dyeing more uniform.

Description

technical field [0001] The invention relates to the field of dyeing technology, in particular to a clean dyeing technology for blended textiles. Background technique [0002] Blended or blended chemical fiber fabrics are textile products made of chemical fibers mixed with other cotton wool, silk, hemp and other natural fibers. It has both the style of polyester and the advantages of cotton fabrics, such as polyester cotton cloth and polyester wool gabardine. Blending is divided into wool-viscose blending, sheep and rabbit wool spinning, TR fabrics, high-density NC fabrics, 3M waterproof mousse fabrics, TENCEL fabrics, Rousai silk, TNC fabrics, composite fabrics, etc. [0003] For example, polyester-cotton blended fabrics are made of polyester as the main component, and are woven with 65%-67% polyester and 33%-35% cotton blended yarns. Polyester-cotton cloth is commonly known as cotton Dacron. Features: It not only highlights the style of polyester but also has the advantage...
