Problems solved by technology

[0002] Roman cloth is a common knitted fabric. Compared with ordinary fabrics, because its surface is not very smooth and has dark horizontal stripes, it not only needs to consume a lot of dyes for dyeing during the dyeing process, but also needs to be dyed after dyeing. Repeated washing and soaping will result in the consumption of a large amount of water and dyes during the processing of Roman cloth, and will generate a large amount of printing and dyeing wastewater during the production process and at the end of the production, which not only causes ecological pollution, but also requires a lot of financial resources Add water purification and sewage treatment, thus increasing its processing cost
The particularity of Roman cloth fabric also leads to poor dyeing effect

Embodiment 1

[0024] Embodiment 1: The impact of pre-setting process on Roman cloth feel

[0025] The one-bath dyeing process of brocade-coated cotton roman cloth in this embodiment is as follows: cloth turning → steaming → presetting → dyeing → color matching → washing → soaping → drying → finished product. in:

[0026] (1) In the pre-setting process:

[0027] ①The setting method adopts steam setting and natural gas open fire heat setting respectively. The temperature is 190°C, the fabric running speed is 55 yards / min, and the air volume is 100r / min. Among them, steam setting is used as comparative test 1, and natural gas open fire heat setting is used as experiment 1.

[0028]② The setting adopts natural gas open flame heat setting, the fabric running speed is 55 yards / min, the air volume is 100r / min, and the setting temperature is lower than 185°C (select 170°C, 180°C and 183°C as representatives), 185-195°C (Choose 185°C, 187°C, 189°C, 191°C, 193°C, 195°C as representatives), higher t...

Embodiment 2

[0037] Embodiment 2: the influence of dyeing process and soaping process on treatment effect

[0038] The one-bath dyeing process of brocade-coated cotton roman cloth in this embodiment is as follows: cloth turning → steaming → presetting → dyeing → color matching → washing → soaping → drying → finished product. in:

[0039] (1) Pre-setting process, the setting method adopts natural gas open flame heat setting, the temperature is 190 ° C, the fabric running speed is 55 yards / min, and the air volume is 100 r / min.

[0040] (2) In the dyeing process, combining figure 1 , the dyeing adopts one-bath dyeing, the dyeing bath ratio is 1:3, the heating rate of stage a→b is 4°C / min, the bath temperature rises to 40°C, and glacial acetic acid is added; the heating rate of stage b→c is 2°C / min, Raise the temperature to 70°C, add 0.5% of acid dye and 1% of rare earth chloride additives, and keep it warm for 10 minutes; the heating rate in the c→d stage is 1.3°C / min, after raising the tem...

Embodiment 3

[0051] Embodiment 3: Utilization of Dyeing Water and Soaping Water

[0052] The one-bath dyeing process of brocade-coated cotton roman cloth in this embodiment is as follows: cloth turning → steaming → presetting → dyeing → color matching → washing → soaping → drying → finished product. in:

[0053] (1) In the presetting process: natural gas open fire is used for heat setting, the temperature is 190°C, the fabric running speed is 55 yards / min, and the air volume is 100r / min.

[0054] (2) In the dyeing process, combining figure 1 , the dyeing adopts one-bath dyeing, the dyeing bath ratio is 1:3, the heating rate of stage a→b is 4°C / min, the bath temperature rises to 40°C, and glacial acetic acid is added; the heating rate of stage b→c is 2°C / min, Raise the temperature to 70°C, add 1.2% of acid dye and 0.1% of rare earth chloride additives, and keep warm for 20 minutes; the heating rate in the c→d stage is 1.3°C / min, after raising the temperature to 98°C, keep warm for 30 minu...

Abstract

The invention relates to a cotton-wrapped-cotton Rome fabric one-bath dyeing process and belongs to the technical field of printing and dyeing technologies in the spinning and manufacturing industry. The cotton-wrapped-cotton Rome fabric one-bath dyeing process comprises the steps of fabric turning, air steaming, pre-sizing, dyeing, color matching, washing, soaping, drying and fished product obtaining, one-bath dyeing is adopted, a Rome fabric to be treated is fed into a vat, and the bath ratio is 1 to 3-4. The process is applied to dyeing of cotton-wrapped-cotton Rome fabrics and has the advantages of being small in water consumption, saving water, uniform in dyeing and the like.
