[0027] Blended dyeing: Add cationic dye owf: 0.1%, retarder owf: 1.0%, dispersant: 1.0g / L, anti-reducing agent: 1g / L, HAC: 3.0g / L at room temperature, and heat up at 0.5°C / min After reach...

Embodiment 2

[0031] A kind of production method of cotton acrylic fiber fabric, is DBR 80 / 2S with the blended fiber yarn specification, and quantity is 763 bobbins, and the bobbin yarn that dyeing luster is dark royal blue is example, and its steps are:

[0032] To loosen the yarn, first loosen the DBR 80 / 2S original blended fiber yarn package purchased from the market on the SSM DP1-W loosening machine, and loosen the original blended fiber yarn by digital winding. The density of the package is 0.32g / m 3 , The weight of a single bobbin is 600g.

[0033] Pre-treatment: First inject 70% of the water into the dyeing vat with the yarn, the bath ratio is 1:10, add 0.5g / L of refining agent, 0.5g / L of soda ash, heat up to 60°C for 20min, drain water, add 30°C, 0.2g / L acetic acid, after 10 minutes of treatment, straight line.

[0034] Blended dyeing: add cationic dye owf: 1.8%, retarder owf: 2.0%, dispersant: 2.0g / L, anti-reducing agent: 3.0g / L, HAC: 5.0g / L at room temperature, at 0.3°C / min Af...

Embodiment 3

[0038] A kind of production method of cotton acrylic fiber fabric, be DBR 32 / 2S with the specification of blended fiber yarn, quantity is 88 bobbins, the bobbin yarn that dyeing luster is green is example, and its steps are:

[0039] To loosen the yarn, first, loosen the DBR 32 / 2S original blended fiber yarn bobbin purchased from the market on the SSM DP1-W loosening yarn machine, and loosen the original blended fiber yarn by digital winding. The density of the bobbin is 0.45g / m 3 , The weight of a single bobbin is 1300g.

[0040] Pre-treatment: first inject 70% water into the dye vat with yarn, bath ratio 1:15, add 10.0g / L of refining agent, 10.0g / L of soda ash, heat up to 110°C, keep warm for 40min, after draining, Add 40°C, 2g / L acetic acid, treat for 20min, and discharge it straight.

[0041] Blended dyeing: Add cationic dye owf: 8.0%, retarder owf: 10.0%, dispersant 10g / L, anti-reducing agent 8.0g / L, HAC 6.5g / L at room temperature, and heat up to 80°C at 8°C / min After ...

Abstract

The invention relates to a production method of a cotton acrylic shell fabric. The method comprises yarn loosing, pretreatment, blend dyeing and aftertreatment, wherein the yarn loosing is carrying out tube loosing on blend fiber yarn by adopting a digital winding manner; the pretreatment is adding a refining agent and sodium carbonate, heating to high temperature, performing heat preservation for a period of time and discharging, and directly adding cold water and acid for treatment; the blend dyeing is adding a retarding agent, a dispersing agent, an antireducer, cationic dyes and HAC, heating and performing heat preservation for twice and discharging materials, adding into water, heating to high temperature and discharging, adding into water at normal temperature, adding a dispersing agent and a soaping agent for water washing at high temperature for twice, discharging after each time of heat preservation, after washing with water once at the normal temperature, adding an activated dye for cotton dyeing, softening, dewatering, oven drying, and performing tube splitting and beaming or spooling, thus obtaining the needed yarns. The production method improves the color precision of the cotton acrylic shell fabric greatly.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a production method of a cotton acrylic fiber fabric with high dyeing quality, low labor intensity and improved efficiency. Background technique [0002] With the development of society, consumers have higher and higher requirements for consumption quality and diversification. Cotton fiber in the traditional sense can no longer meet the needs of such consumers. Therefore, blended fibers are favored by more and more consumers. Acceptance and love, as a high-end yarn-dyed fabric in textiles, because it involves more processes and functional finishing, it has higher requirements for color and yarn quality. [0003] Traditional cotton acrylic yarn dyeing has problems such as: long production process, relatively high labor intensity, poor dyeing quality, more hairiness, inaccurate color, large layer difference and poor strength, and low production efficiency, which affects yarn-dye...
