Problems solved by technology

Due to the limitations of the precision of the printing and dyeing equipment itself and the concentration uniformity and stability of the dyeing and finishing working solution, the open-width pad dyeing process inevitably has local forces on the fabric, uneven liquid, and uneven heating, which affects level dyeing. There may be color differences between left, middle, right, front and back, front and back, and even color code differences.
The color uniformity of the traditional overflow process is better than that of the open width process, but generally there is no mercerizing process, resulting in low dye uptake and color fastness of the finished product, and the dyed cotton part is darker in color and the cloth surface is not enough. Flat, fine, not advanced enough

Embodiment 1

[0034] Embodiment 1: gray cloth quality 150g / m 2 , polyester / cotton 60 / 40, dyed.

[0035] The specific steps are as follows: fabric singeing: the fabric adopts double burning process, gray cloth singeing and singeing after dyeing, one positive and one reverse each time; boiled and bleached in overflow dyeing machine; mercerized in straight roll-cloth folder On-machine mercerizing; dyeing polyester and over-dyeing reactive dyes in a high-temperature and high-pressure overflow dyeing machine; padding and finishing auxiliaries on an even padding machine, and steaming in a KD95 tank steamer.

[0036] In this example:

[0037] Cooking and bleaching: atmospheric pressure overflow dyeing machine, the prescription is: sodium hydroxide 4g / l, hydrogen peroxide 7g / l, hydrogen peroxide stabilizer DS (manufactured and sold by Shandong Julong Chemical) 3g / l, refining agent ZX95 (Shijiazhuang Huancheng Chemical Factory) Manufacturing and sales) 13g / l; liquor ratio 1:15, temperature 95°C, t...

Embodiment 2

[0044] Embodiment 2: gray cloth quality 125g / m 2 , polyester cotton 50 / 50, whitening.

[0045] The specific steps are as follows: fabric singeing (one positive and one reverse); boiling and bleaching in the overflow dyeing machine; mercerizing on the cloth clip mercerizing machine; adding brightener CPS and 4BK-B (Zhejiang Chuanhua Company) in the overflow dyeing machine Provide), or pad whitening agent on the even padding car; pad the post-finishing auxiliary working liquid NSD with low formaldehyde non-ironing resin on the even padding car, and steam it in the KD95 tank steamer.

[0046] In this example:

[0047]Cooking and bleaching: atmospheric pressure overflow dyeing machine, the prescription is: sodium hydroxide 5g / l, hydrogen peroxide 10g / l, hydrogen peroxide stabilizer DS (manufactured and sold by Shandong Julong Chemical Factory) 2g / l, refining agent ZX95 (Shijiazhuang Huancheng Chemical Factory manufacturing and sales) 10g / l; liquor ratio 1:10, temperature 90°C, t...

Embodiment 3

[0054] Embodiment 3: gray cloth quality 125g / m 2 , polyester cotton 50 / 50, whitening.

[0055] The specific steps are as follows: fabric singeing (one positive and one reverse); boiling and bleaching in the overflow dyeing machine; mercerizing on the cloth clip mercerizing machine; adding brightener CPS and 4BK-B in the overflow dyeing machine (Zhejiang Chuanhua) , or pad whitening agents CPS and 4BK-B (Zhejiang Chuanhua) on a uniform pad car; pad the finishing aid low-formaldehyde non-ironing resin NSD on a uniform pad car, and steam in a KD95 can steamer.

[0056] In this example:

[0057] Cooking and bleaching: atmospheric pressure overflow dyeing machine, the prescription is: sodium hydroxide 5g / l, hydrogen peroxide 10g / l, hydrogen peroxide stabilizer DS (manufactured and sold by Shandong Julong Chemical) 4g / l, refining agent ZX95 (Shijiazhuang Huancheng Chemical Factory) Manufacturing and sales) 15g / l; liquor ratio 1:20, temperature 100°C, time 40min. If the whiteness ...

Abstract

The process of dyeing and finishing covered yarn fabric includes the steps of preparing gray cloth, singeing, boiling and rinsing in an overflow dyeing machine, finishing, mercerizing, dyeing or whitening, finishing and full decatizing. The process has combined overflow processing and open width processing, and includes overflow boiling and rinsing step, overflow dyeing step and other open width steps. Compared with conventional all open width process, the present invention has improved less dyeing defects, less color difference and improved hand feeling; and compared with common overflow process, the present invention has increased mercerizing treatment, raised fabric vividness and color fastness, and improved visual quality of the fabric.

Description

technical field [0001] The invention relates to a method for dyeing and finishing core-spun yarn fabrics. Background technique [0002] Pure cotton fabric has excellent wearing comfort and good hand feeling, but poor wrinkle resistance. If it is not ironed after washing, it will have a poor appearance when worn; although conventional polyester-cotton blended fabrics have improved wrinkle resistance, they have poor hand feeling and poor contact comfort. , strong sense of chemical fiber, the product grade is not high. For uniform shirt fabrics, it is required to have a crisp appearance, comfortable wearing, and excellent washability, that is, it can be worn without ironing after washing, and maintain a flat and crisp appearance. [0003] For this reason, the core-spun yarn formed by polyester filament outsourcing cotton fiber (especially outsourcing long-staple cotton fiber) is used, and the fabric formed by weaving, dyeing and finishing is soft cotton fiber because the surfa...
