Problems solved by technology

Because conventional denim fabrics are generally dyed with indigo dye, and indigo dye has poor fastness, post-mercerizing finishing will make the dyed color of the cloth surface lighter, which wastes dye and is difficult to control the color. The mercerizing liquid cannot be recycled because it contains color. Increased discharge of colored wastewater is not conducive to clean production of energy saving and emission reduction
Moreover, in the existing denim fabric mercerizing technology, a certain amount of penetrating agent needs to be added
Phosphate-based alkali-resistant penetrants currently used contain phosphorus, so their application is limited under the current environmental protection requirements; some penetrants have poor penetrating effects in a short period of time due to the high concentration of alkali in the mercerizing liquid , so that the gloss and softness of the fabric after mercerizing are not ideal, and the color is uneven and there is color difference, which affects the quality of denim fabrics

Embodiment 1

[0029] The 16s cotton / tencel 70 / 30 yarn is wound on the warp beam through warping, and a certain tension is applied to the yarn on the warp beam to form a bundle yarn. Each bundle yarn contains 400-500 yarns. Each bundle of yarn is wound on a warp beam to prepare a ball warp. The bundle yarns on 12-25 ball warps are arranged as a whole and fed into the guide roller at the same time. The ball warp is directly mercerized and then the warp beam is dyed. Process, after multiple oxidation processes, the ball is finally dyed.

[0030] The ball warp mercerizing process formula in the above scheme is:

[0031]

[0032] The preparation method of the high-efficiency mercerizing penetrant in the above scheme is:

[0033] Accurately weigh 30g of isotridecyl alcohol polyoxyethylene ether and place it in a completely dry three-necked flask with a thermometer; install the stirring device, start the stirrer, the stirring degree is 800r / min, and start to heat up to 100 after evenly stirring -160℃, ...

Abstract

The invention discloses a ball warp mercerizing technology of denim production and a preparation method of a high efficiency mercerizing penetrating agent. The ball warp mercerizing technology comprises processing finished warp to obtain a warp bundle in the former process of the denim production, winding each warp bundle on a warp beam to obtain ball warp, directly mercerizing the ball warp without refining, and directly dying the ball warp without alkali liquor padding before dying after mercerizing. According to the ball warp mercerizing technology, the traditional denim fabric post-mercerizing finishing process is replaced by warp pre-mercerizing treatment in the former process so that denim production quality is guaranteed, two dyeing and finishing processes are avoided, mercerizing effects are good, the dyed yarn has good surface gloss and color and gloss are uniform. The ball warp mercerizing technology is suitable for energy-saving emission-reduction clean production.

Description

Technical field: [0001] The invention relates to a ball warp mercerizing process and the preparation of a high-efficiency mercerizing penetrant in the production of denim fabrics, and belongs to the technical field of textile dyeing and finishing. Background technique: [0002] Since the invention of denim clothing in the United States, denim has become the world's clothing with its rugged, unrestrained, unrestrained, generous, natural style, compact and thick structure, soft and comfortable wearing, and strong and durable texture. The most successful and well-known clothing product in the history of the industry has a huge market share in the international textile market. The denim industry products are developing in the direction of high-grade, personalized, functional and fashionable. [0003] In recent years, people have found that after mercerizing denim, the fabric surface feels comfortable, has good luster, bright whitening effect and clear fabric style, which gives denim f...
