[0016] A kind of fabric dyeing process utilizing dyeing accelerator DA Plus, comprises the steps:

[0017] (1) Pretreatment: wet the fabric to be dyed;

[0018] (2) Dyeing: dyeing under the conditions of reactive dye 2%, sodium sulfate 40g / L, dyeing accelerator DA Plus 4g / L, dyeing time 60min, dyeing temperature 60°C, bath ratio 1:10;

[0019] (3) Post-processing: The fabric in step (2) is sequentially subjected to soap washing, water washing, and drying procedures to obtain colored fabrics.

Embodiment 2

[0021] A kind of fabric dyeing process utilizing dyeing accelerator DA Plus, comprises the steps:

[0022] (1) Pretreatment: wet the fabric to be dyed;

[0023] (2) Dyeing: Dyeing under the conditions of 1% reactive dye, 50g / L sodium sulfate, 0.5g / L dyeing accelerator DA Plus, dyeing time is 30min, dyeing temperature is 50℃, liquor ratio is 1:8;

[0024] (3) Post-processing: The fabric in step (2) is sequentially subjected to soap washing, water washing, and drying procedures to obtain colored fabrics.

Embodiment 3

[0026] A kind of fabric dyeing process utilizing dyeing accelerator DA Plus, comprises the steps:

[0027] (1) Pretreatment: wet the fabric to be dyed;

[0028] (2) Dyeing: Dyeing under the conditions of reactive dye 5%, sodium sulfate 20g / L, dyeing accelerator DA Plus 6g / L, dyeing time 80min, dyeing temperature 90℃, bath ratio 1:15;

Abstract

The invention relates to a textile dyeing process utilizing a dyeing promoter DA Plus. The textile dyeing process comprises the following steps: (1) pre-treating: wetting a textile to be dyed; (2) dyeing: dyeing the textile under conditions of 1-5% of active dye, 20-50 g / L of sodium sulfate and 0.6-6 g / L of dyeing promoter DA Plus, wherein the dyeing time is 30-80min, the dyeing temperature is 50-90 DEG C, and the bath ratio is (1:8)-(1:15); (3) post-treating: sequentially carrying out soaping, washing and drying procedures to obtain a dyed textile. The textile dyeing process provided by the invention has the advantages that the dosage of the dyeing promoter DA Plus is small, the cost is low, the energy source is saved, the K / S value is higher than the K / S value when utilizing other alkali as an alkali agent, the crockfastness and the washing fastness are improved, such carcinogenic azo and aromatic compounds as APEO and formaldehyde are not contained, the solubility and washing property are good, the dye yield is high, the reproducibility is good and the dyeing defect is obviously perfected.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing and finishing, and in particular relates to a fabric dyeing process using a dyeing accelerator DA Plus. Background technique [0002] In the dyeing of reactive dyes, the traditional alkaline agents used in the fixation reaction are relatively mild soda ash and trisodium phosphate. Alkali agent (soda ash) has good color fixing effect, but there are disadvantages such as large dosage, inconvenient heating, and easy agglomeration to block pipes. In order to solve these problems, recently, some alkali substitutes have been launched in the auxiliary market as special alkali agents for reactive dyes to fix the color, which are used to replace traditional alkali agents such as soda ash. Such as the liquid mixed alkali agent ALkaflo RMT developed by Bayer Company of the United States, and the liquid mixed alkali agent developed by Birmingham Company of the United States under the name Burco NP-Q Sa...
