Embodiment 1

[0028] Embodiment 1: a kind of post-finishing process of tencel / cotton fabric, the specific steps of the post-finishing process of described tencel / cotton fabric are as follows:

[0029] Step 1. First perform two positive and two reverse singeing processes on the fabric; a speed of 90m / min is used in the singeing process.

[0030] Step 2. Then carry out the hot alkali desizing treatment process; the desizing treatment process includes steaming after padding in hot solution, then washing with hot water, and finally rinsing with cold water.

[0031] The hot solution is formed by mixing NaOH and detergent in a mass ratio of 4:1 and then pouring it into an aqueous solution at 80°C, wherein the concentration of NaOH in the hot solution is 4g / L, and the concentration of detergent is 1g / L , the bath ratio of fabric desizing and padding is 1:20, the time of steaming is 50min; the temperature of hot water washing is 80℃.

[0032] Step3, then use the cloth clip mercerizing machine to c...

Embodiment 2

[0037] Embodiment 2: a kind of post-finishing process of tencel / cotton fabric, the specific steps of the post-finishing process of described tencel / cotton fabric are as follows:

[0038] Step 1. First perform two positive and two negative singeing processes on the fabric; a speed of 100m / min is used in the singeing process.

[0039] Step 2. Then carry out the hot alkali desizing treatment process; the desizing treatment process includes steaming after padding in hot solution, then washing with hot water, and finally rinsing with cold water.

[0040] The hot solution is formed by mixing NaOH and detergent in a mass ratio of 4:1 and then pouring it into an aqueous solution at 80°C, wherein the concentration of NaOH in the hot solution is 8g / L, and the concentration of detergent is 2g / L , the bath ratio when desizing and padding the fabric is 1:20, the steaming time is 70min; the temperature of hot water washing is 90°C.

Embodiment 3

[0046] Embodiment 3: a kind of post-finishing process of tencel / cotton fabric, the specific steps of the post-finishing process of described tencel / cotton fabric are as follows:

[0047] Step 1. First perform two positive and two negative singeing processes on the fabric; a speed of 86m / min is used in the singeing process.

[0048] Step 2. Then carry out the hot alkali desizing treatment process; the desizing treatment process includes steaming after padding in hot solution, then washing with hot water, and finally rinsing with cold water.

[0049] The hot solution is formed by mixing NaOH and detergent in a mass ratio of 4:1 and then pouring it into an aqueous solution at 80° C., wherein the concentration of NaOH in the hot solution is 6 g / L, and the concentration of detergent is 1.5 g / L. L, the bath ratio of fabric desizing and padding is 1:20, the steaming time is 60min; the temperature of hot water washing is 85°C.

Abstract

The invention relates to a finishing process of tencel / cotton fabric, which belongs to the technical field of textile dyeing and finishing. In the present invention, the singeing process of two fronts and two reverses is performed on the fabric first; then the hot alkali desizing treatment process is performed; then the cloth clip mercerizing machine is used to carry out the widening mercerizing process; The soft finishing process of dipping and rolling; finally, it is pre-shrunk and finished before the finished product. The invention greatly improves the mercerizing effect and softness of the fabric, thereby improving the quality and product grade of the Tencel / cotton fabric. The finished fabric has a good silky feel, soft light and color, bright colors, comfortable and breathable, and can be widely used in high-end home textiles and clothing fabrics.

Description

technical field [0001] The invention relates to a finishing process of tencel / cotton fabric, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] The cohesion between tencel fibrils is weak, and the fibers will be broken in the longitudinal direction to form loose fibers under the action of mechanical force in wet state, and then form a special velvet effect. In the wet state, the fibers expand laterally by 40%, but the length remains unchanged. After the fabric is wet-processed, the gaps between the yarns become larger, giving the fabric a sense of drape and fluidity. Tencel fiber has high crystallinity, long crystal region, and small difference in dry and wet strength. The dry strength is close to that of polyester fiber, and the wet strength is only decreased by 15%, which is higher than that of liquid cotton. The wet strength of viscose fiber has decreased by 50%. Tencel fiber is dyed with reactive dyes, which have strong a...
