Problems solved by technology

Although dyeing and finishing can effectively improve the performance of fabrics, dyeing and finishing mainly depends on chemical processing of fabrics. In this process, repeated washing and drying operations are required, so more energy is consumed
At present, high energy consumption has become one of the bottlenecks restricting the development of dyeing and finishing

Embodiment 1

[0088] In this embodiment, the fabric to be dyed and finished is a cotton woven fabric, the gram weight is 4.5oz, and the length is 1000 yards. The pressure of the water wash roll thus selected was 30N. The pressures of the multiple pairs of the first water-washing rolls, the multiple pairs of the second water-washing rolls, the multiple pairs of the third water-washing rolls, and the multiple pairs of the fourth water-washing rolls are all 30N.

[0089] The dyeing method is:

[0090] S01: Singeing treatment. The feeding speed of the singeing treatment was 80 m / min.

[0091]S02: Desizing treatment, first washing. Desizing treatment is performed on the singeed fabric to obtain a desizing fabric; and then a first water washing is performed on the desizing fabric to obtain a first water washing fabric. The rotational speed of the first water wash roll was 90 m / min. The number of the first water-washing rolls is 4 pairs, and 2 pairs of the 4 pairs of first-water-washing rolls...

Embodiment 2～ Embodiment 5

[0097] Compared with Example 1, Examples 2 to 5 are different in that the grammage of the fabric to be dyed and finished, the pressure of the washing roll, and the rotational speed of the washing roll are different. The parameters of the fabric to be dyed and finished and the parameters of the dyeing and finishing process in the dyeing and finishing process in Examples 1 to 5 are shown in Table 1.

Abstract

The invention relates to a dyeing and finishing method. The dyeing and finishing method comprises the following steps: acquiring the gram weight FAW of a fabric to be dyed and finished; the pressure F of a washing roller is selected according to the gram weight FAW, the pressure F of the washing roller is the pressure of a roller pressing the fabric to be dyed and finished during washing in each step of the dyeing and finishing method, and the gram weight FAW and the pressure F meet the following relation: when FAW is less than 5oz, F is less than or equal to 30N; when 5oz < = FAW < = 7oz, 30N < = F < = 40N; and when FAW is greater than 7oz, F is greater than or equal to 40N. The dyed and finished fabric is subjected to desizing treatment, first water washing, mercerizing treatment, second water washing, liquid ammonia treatment and third water washing, and third water-washed fabric is obtained. The adaptive washing roller pressure is selected according to the gram weight of the fabric to be dyed and finished, so that the energy consumption in the dyeing and finishing process can be effectively reduced under the condition of keeping a good dyeing and finishing effect, and the development of fabric dyeing and finishing is promoted.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a dyeing and finishing method. Background technique [0002] In the textile process, dyeing and finishing is an important means to improve the performance of fabrics. By dyeing and finishing fabrics such as fibers, yarns, and cloth, the comprehensive properties of the fabrics such as fastness and deformation resistance can be effectively improved. Although dyeing and finishing can effectively improve the performance of fabrics, dyeing and finishing mainly relies on chemical processing of fabrics. In the process, repeated washing and repeated drying are required, so more energy is required. At present, high energy consumption has become one of the bottlenecks restricting the development of dyeing and finishing. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a dyeing and finishing method that can effectively reduce energy consumption. [0004] In ...
