阅读说明：本技术 一种全棉染色麻灰面料的染色工艺 (Dyeing process of all-cotton dyed grey linen fabric ) 是由 唐海国 石大均 田春生 黄伟 朱伟强 于 2019-11-26 设计创作，主要内容包括：本发明公开了一种全棉染色麻灰面料的染色工艺,包括以下步骤,首先,将棉纱进行阳离子处理；接着,将阳离子处理过的棉纱织成单面汗布,将圆筒单面汗布入缸前通过反布机反布。该全棉染色麻灰面料的染色工艺缩短时长并不添加盐和碱。(The invention discloses a dyeing process of all-cotton dyed gray linen fabric, which comprises the following steps of firstly, carrying out cationic treatment on cotton yarn; then, the cotton yarn treated by the positive ions is woven into single-sided single-jersey, and the single-sided cylinder single-sided single-jersey is reversely woven by a reverse loom before being put into a cylinder. The dyeing process of the all-cotton dyed gray fabric shortens the time and does not add salt and alkali.)

1. A dyeing process of all-cotton dyed gray fabric is characterized by comprising the following steps: comprises the following steps of (a) carrying out,

firstly, carrying out cationic treatment on cotton yarns;

then, weaving the cotton yarn treated by the cations into single-sided single-jersey, and reversely weaving the single-sided single-jersey of the cylinder by a reverse loom before the single-sided single-jersey is put into the cylinder;

then, oxygen bleaching, namely adding 1% of multifunctional pretreatment agent, 1.5% of low-temperature high-efficiency pretreatment agent and 2% of hydrogen peroxide by mass percentage, heating to 55 ℃ and maintaining for 40min, and then adding 0.6% of glacial acetic acid and operating at normal temperature for 10 min;

finally, disperse dye and 1% glacial acetic acid are added for dyeing after the cloth bottom is bleached by oxygen, and salt and alkali are not added in the dyeing process.

2. The dyeing process of the all-cotton dyed gray fabric according to claim 1, characterized in that: the cotton yarn is treated with cation by adding a compound of quaternary ammonium salt type containing chlorohydrin group, impregnating and rolling, and then grafting cation group on the cotton yarn fiber.

3. The dyeing process of the all-cotton dyed gray fabric according to claim 1, characterized in that: the multifunctional pretreatment agent is GD-109.

The technical field is as follows:

the invention relates to the field of textile printing and dyeing, in particular to a dyeing process of all-cotton dyed flaxseed grey fabric.

Background art:

The invention content is as follows:

the invention aims to solve the technical problem of providing a dyeing process of an all-cotton dyed gray fabric, which can shorten the time and does not add salt and alkali.

The technical proposal of the invention is to provide a dyeing process of all-cotton dyed gray fabric, which comprises the following steps,

firstly, carrying out cationic treatment on cotton yarns;

then, weaving the cotton yarn treated by the cations into single-sided single-jersey, and reversely weaving the single-sided single-jersey of the cylinder by a reverse loom before the single-sided single-jersey is put into the cylinder;

then, oxygen bleaching, namely adding 1% of GD-109 (multifunctional pretreatment agent), 1.5% of low-temperature high-efficiency pretreatment agent and 2% of hydrogen peroxide by mass percent, heating to 55 ℃ and maintaining for 40min, and then adding 0.6% of glacial acetic acid and operating at normal temperature for 10 min;

finally, disperse dye and 1% glacial acetic acid are added for dyeing after the cloth bottom is bleached by oxygen, and salt and alkali are not added in the dyeing process.

The invention has the beneficial effects that: the cotton yarn is subjected to cationization treatment, the dyeing is alkali-free and salt-free, the sewage treatment pressure is greatly reduced, the cost is saved, the dyed cotton yarn has a natural ramie grey effect, and compared with the traditional yarn-dyed ramie grey production process, the production process is quick and the cost is low.

The specific implementation mode is as follows:

the invention will be further illustrated with reference to specific embodiments:

a dyeing process of all-cotton dyed gray fabric comprises the following steps,

firstly, cotton yarn is subjected to cation treatment, specifically, a modifier such as a chlorohydrin group-containing quaternary ammonium salt type compound is added, and after impregnation and rolling, cationic groups are grafted on cotton yarn fibers, so that the dyeing property of the fibers is improved;

then, weaving the cotton yarn treated by the cations into single-sided single-jersey, and reversely weaving the single-sided single-jersey of the cylinder by a reverse loom before the single-sided single-jersey is put into the cylinder;

then, oxygen bleaching, namely adding 1% of GD-109 (multifunctional pretreatment agent), 1.5% of low-temperature high-efficiency pretreatment agent and 2% of hydrogen peroxide by mass percentage, heating to 55 ℃ and maintaining for 40min, and then adding 0.6% of glacial acetic acid and running for 10min at normal temperature, wherein the low-temperature high-efficiency pretreatment agent is Desmorin LTB;

finally, disperse dye and 1% glacial acetic acid are added for dyeing after the cloth bottom is bleached by oxygen, and salt and alkali are not added in the dyeing process.

The invention has the beneficial effects that: the cotton yarn is subjected to cationization treatment, the dyeing is alkali-free and salt-free, the sewage treatment pressure is greatly reduced, the cost is saved, the dyed cotton yarn has a natural ramie grey effect, and compared with the traditional yarn-dyed ramie grey production process, the production process is quick and the cost is low.
