Embodiment 1

[0033] (1) At room temperature, add 3g of reactive red 9#, 1g of leveling agent 821, 1g of sodium bicarbonate and 100g of nylon-cotton blended fabric to 1000ml of water in sequence, raise the temperature to 60°C at a rate of 1°C / min, and then Keep warm for 30 minutes, add alkali and then keep warm for 30 minutes to complete the dyeing of cotton and obtain dyed semi-finished products;

[0034] (2) Add glacial acetic acid to the dyed semi-finished product obtained in step (1) to adjust the pH to 4.5, then raise the temperature to 80°C at a rate of 1°C / min, keep it warm for 30 minutes, cool down to room temperature, drain, wash with water, and then Raise the temperature to 98°C for soaping, then cool down to room temperature, wash with water, and dry to obtain the finished dyed product. The performance data of the dyed finished product obtained are shown in Table 1.

Embodiment 2

[0036] (1) At room temperature, add reactive blue 4# 3g dye, leveling agent OP 1g, sodium bicarbonate 1g and nylon-cotton blended fabric 100g to 1000ml of water in turn, heat up to 60°C at a rate of 1°C / min, and then Keep warm for 30 minutes, add alkali and then keep warm for 30 minutes to complete the dyeing of cotton and obtain dyed semi-finished products;

[0037] (2) Add glacial acetic acid to the dyed semi-finished product obtained in step (1) to adjust the pH to 4.5, then raise the temperature to 80°C at a rate of 1°C / min, keep it warm for 30 minutes, cool down to room temperature, drain, wash with water, and then Raise the temperature to 98°C for soaping, then cool down to room temperature, wash with water, and dry to obtain the finished dyed product. The performance data of the dyed finished product obtained are shown in Table 1.

Embodiment 3

[0039] (1) At room temperature, add reactive red 9# 3g, leveling agent AN 1g, sodium bicarbonate 1g and nylon-cotton blended fabric 100g to 1000ml of water in turn, heat up to 60°C at a rate of 1°C / min, and then Keep warm for 30 minutes, add alkali and then keep warm for 30 minutes to complete the dyeing of cotton and obtain dyed semi-finished products;

[0040] (2) Add glacial acetic acid to the dyed semi-finished product obtained in step (1) to adjust the pH to 4.5, then raise the temperature to 80°C at a rate of 1°C / min, keep it warm for 30 minutes, cool down to room temperature, drain, wash with water, and then Raise the temperature to 98°C for soaping, then cool down to room temperature, wash with water, and dry to obtain the finished dyed product. The performance data of the dyed finished product obtained are shown in Table 1.

Abstract

A disclosed dyeing technology for brocade-cotton blended fabric comprises the following steps: (1) adding a dye and an auxiliary agent into water to prepare a dye solution, controlling the temperature of the dye solution at 20-30 DEG C, then adding brocade-cotton blended fabric, keeping the temperature for 5-10 min, heating to 55-65 DEG C at a speed of 1-3 DEG C/min, keeping the temperature for 20-40 min, adding an alkali to adjust pH to 9-10 for dye fixation, then keeping the temperature for 20-40 min to obtain a dyed half-finished product; and (2) adding glacial acetic acid into the dyed half-finished product to adjust pH to 4-4.5, heating to 80-90 DEG C at a speed of 1-3 DEG C/min, successively performing water washing, soaping, water washing and drying to obtain the dyed finished product. The level-dyeing property of the dyeing technology and the dye spreadability on fabric of the dye are excellent, hydrolyzed dye is less, dye fixation rate is improved, discharged wastewater is reduced, and the dyeing technology has the advantages of being substantial in energy-saving, emission-reduction and environment-friendly.

Description

technical field [0001] The invention belongs to the field of textile dyeing, and in particular relates to a dyeing process of nylon-cotton blended fabric. Background technique [0002] Cotton nylon fabric is currently a popular clothing fabric. Among them, cotton fiber feels soft, has good air permeability and moisture absorption, and is comfortable to wear, but it is easy to wrinkle; nylon fiber has high resilience and fatigue resistance, and has good moisture absorption performance. After interweaving cotton and nylon, the fabric can not only have the advantages of nylon and cotton fibers, but also overcome their respective shortcomings, showing a strong body and smooth feel. [0003] When dyeing cotton nylon fabric, due to the difference in chemical structure of nylon fiber and cotton fiber, its dyeing process has particularity. At present, the main processes of cotton nylon fabric dyeing include reactive / acid two-bath two-step method, acid dye / reactive dye one-bath two-...
