Problems solved by technology

[0002] Polyester-cotton blended fabrics are composed of two fibers with different properties. The dyeing and finishing process needs to take into account the fibers of two different properties. The traditional processing flow is to pre-treat the cotton according to the pre-treatment process, then dyeing and washing reduction washing, and then dyed cotton soaping , the whole process takes more than 12 hours, the energy and water consumption is large, the production cost is high, and a large amount of waste water containing high pollutants is discharged at the same time

Embodiment Construction

[0015] The present invention will be further explained below in conjunction with specific examples.

[0016] A dyeing process of blended fabrics, the process flow is bath pretreatment → dyeing of polyester and brocade sticking in the same bath → soaping → functional post-finishing;

[0017] 1) Bath pretreatment:

[0018] According to the bath ratio of 2:5, put the gray cloth and clean water in the machine tank; add 3g / L scouring agent, 5g / L hydrogen peroxide stabilizer, and 2g / L hydrogen peroxide; heat up to 98°C at a speed of 2°C / min, and keep warm for 30min ; Cool down to 50°C, discharge waste liquid, and wash with water.

[0019] 2) Dyeing of polyester and nylon in one bath:

[0020] According to the bath ratio of 2:9, put the pre-treated polyester cotton cloth and clear water in the machine tank; add disperse dyes, neutral color-fixing reactive dyes, sodium chloride 43-50g / L, leveling agent 2-5g / L ;Raise the temperature to 130°C at a rate of 3°C / min, and keep it warm fo...

Abstract

The invention discloses a dyeing process of a blended fabric. The process flow includes the steps of bath pretreatment, polyester brocade viscose one-bath dyeing, soaping and functional after-treatment.

Description

technical field [0001] The invention relates to a dyeing and finishing process of textiles, in particular to a dyeing process of blended fabrics, belonging to the field of dyeing and finishing of fabrics. Background technique [0002] Polyester-cotton blended fabrics are composed of two fibers with different properties. The dyeing and finishing process needs to take into account the fibers of two different properties. The traditional processing flow is to pre-treat the cotton according to the pre-treatment process, then dyeing and washing reduction washing, and then dyed cotton soaping , the whole process takes more than 12 hours, the energy and water consumption is large, the production cost is high, and a large amount of waste water containing high pollutants is discharged at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a dyeing process of blended fabrics, which uses a short process of pretreatment and one-bath dyei...
