Problems solved by technology

[0005] One of the most important processes in the dyeing and finishing process of Tencel is singeing. Tencel fibers are smooth and delicate, and are prone to fibrillation and wrinkling, while ramie fibers are hard and contain many impurities, and are prone to fluff. Therefore, Tencel / The ramie interwoven plain weave has more hairiness, and the ramie fiber is thicker, so the singeing processing is more important than the general cotton cloth. Singeing is to quickly pass the fabric through the flame or rub the red hot metal surface to burn off the surface of the fabric. Fluff, so that the surface of the fabric becomes smooth and clean, so as to prevent defects in subsequent processing, but in the existing singeing process, the temperature is often too low (under-burning), the burnt is not clean, the fluff is spherical, and color spots appear during dyeing This is because the hairiness is not in full contact with the inner flame, resulting in insufficient temperature and incomplete combustion, which seriously affects the quality of dyeing and finishing

Embodiment 1

[0046] see figure 1 , a kind of dyeing and finishing process of cold-sense tencel hemp, comprising the following steps:

[0047] S1, select the fabric that adopts ordinary tencel ply yarn as warp yarn and ramie single yarn as weft yarn to interweave, and carry out gray cloth inspection;

[0048] S2. Adopt a gas singeing machine with two positive and two negative burners, a temperature of 800°C, a vehicle speed of 100m / min, and a singeing grade of 4. The fabric burns off irregular hairs by contacting with a hot magnetic rod;

[0049] S3. Adopt the one-step method of cold pad-batch descouring and bleaching. First, the fabric is soaked in the working solution (3 grids), then rolled up and sealed with a plastic film, and rotated at room temperature at 8r / min for 20h, and the end Then wash with 2 grids of hot water, then steam with 4 grids, and finally wash with 4 grids of hot water, 2 grids of warm water and 2 grids of cold water;

[0050] S4, the fabric is treated by semi-merce...

Embodiment 2

[0066] see figure 1 , a kind of dyeing and finishing process of cold-sense tencel hemp, comprising the following steps:

[0067] S1, select the fabric that adopts ordinary tencel ply yarn as warp yarn and ramie single yarn as weft yarn to interweave, and carry out gray cloth inspection;

[0068] S2. Adopt a gas singeing machine with two positive and two negative burners, a temperature of 850°C, a vehicle speed of 140m / min, and a singeing grade of 4. The fabric burns off irregular hairs by contacting with a hot magnetic rod;

[0069] S3. Using the one-step method of cold pad-batch descouring and bleaching, first pad the fabric with the working solution (3 grids), then roll it up and seal it with a plastic film, and carry out 9r / min rotating cold-batch at room temperature for 22h, and end Then wash with 2 grids of hot water, then steam with 4 grids, and finally wash with 4 grids of hot water, 2 grids of warm water and 2 grids of cold water;

Embodiment 3

[0078] see figure 1 , a kind of dyeing and finishing process of cold-sense tencel hemp, comprising the following steps:

[0079] S1, select the fabric that adopts ordinary tencel ply yarn as warp yarn and ramie single yarn as weft yarn to interweave, and carry out gray cloth inspection;

[0080] S2. A gas singeing machine is adopted, with two positive and two negative burners, a temperature of 900°C, a vehicle speed of 180m / min, and a singeing grade of 4. The fabric burns off irregular hairs by contacting with a hot magnetic rod;

[0081]S3. Adopt the one-step method of cold pad-batch descouring and bleaching. First, the fabric is soaked in the working solution (3 grids), then rolled up and sealed with plastic film, and rotated at room temperature at 10r / min for 24 hours. Then wash with 2 grids of hot water, then steam with 4 grids, and finally wash with 4 grids of hot water, 2 grids of warm water and 2 grids of cold water;

Abstract

The invention discloses a dyeing and finishing process of cold-feeling tencel linen, and belongs to the technical field of textile fabric production. According to the dyeing and finishing process, ina singeing process, dipping treatment can be innovatively performed on irregular hairiness on a fabric, and the hairiness is dried after absorbing a nano ferromagnetic solution, and endowed with magnetism; during singeing, a hairiness absorbing ball arranged at a fire hole is used for generating a magnetic attraction effect on the fabric, so that on one hand, the hairiness is forced to be highly separated from the fabric, the singeing effect is improved, the damage to the fabric is reduced, and on the other hand, the hairiness can be forced to be in full contact with inner flame, thereby avoiding underburnt influence caused by over-low temperature, and meanwhile, the damage to the fabric and energy consumption of gas brought by high temperature of outer flame are avoided. Compared with anexisting singeing process, the process has the advantages that the smoothness effect of the fabric can be remarkably improved, the pressure of subsequent procedures is reduced, a finished product is obtained through cold pad-batch, mercerization, dyeing, enzyme treatment, resin treatment, drying and tentering setting in sequence after singeing is finished, and the dyeing and finishing effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of textile fabric production, and more specifically relates to a dyeing and finishing process of cool-feeling tencel hemp. Background technique [0002] Tencel is a kind of cellulose fiber. It adopts solvent spinning technology. The dry strength is slightly lower than that of polyester, but it is obviously higher than that of ordinary viscose fiber. The wet strength is significantly improved compared with viscose. It has very high rigidity and good Dimensional stability after washing (shrinkage rate is only 2%), high hygroscopicity, fiber cross-section is round or oval, beautiful luster, soft hand feeling, good drapability, and good airiness. [0003] Tencel hemp fabric is a woven fabric that interweaves or blends new regenerated cellulose fiber tencel and natural flax. Generally, warp direction tencel is interwoven with weft direction hemp or blended hemp, and warp direction blended hemp is interwoven with ...
