Embodiment 1

[0021] Gray fabric specification: 106” / 32s*21s / 133*60, 30% cotton 70% Tencel, 1 / 3 twill, weft surface coverage 75%.

[0022] The gray cloth goes through the following processes in turn:

[0023] (1) Singeing: Slightly singeing on the front, with a speed of 115 m / min.

[0024] (2) Enzymatic desizing: amylase 8g / L, stack at 55°C for 7 hours, then wash with hot water for 5 times.

[0025] (3) Rebleaching: 100% hydrogen peroxide 2g / L, sodium carbonate 5g / L, hydrogen peroxide stabilizer 5g / L, chelating dispersant 5g / L, steam with saturated steam for 50min, then wash with hot water for 4 times.

[0026] (4) Soft finishing: bulking agent 10g / L, urea 20g / L, setting temperature 140°C, vehicle speed 35 m / min.

[0027] (5) Brushing: the front side is brushed twice, the reverse side is brushed once, and the sequence of brushing is the front, the back, and the front. Among them, the front napping method is as follows: the speed of the clockwise roller is 220 rpm, and the pressure of the...

Embodiment 2

[0032] On the basis of Example 1, the difference from Example 1 is: gray fabric specification: 106” / 32s*32s / 2 / 133*65, 50% cotton 50% Tencel, 1 / 5 satin weave, weft surface coverage was 83%.

[0033] The difference in method steps (1)~(8) is:

[0034] (1) The speed of singeing is 120 m / min;

[0035] (2) Amylase 10g / L, stack at 60°C for 6h, and then wash with hot water for 5 times.

[0036] (3) Rebleaching: 100% hydrogen peroxide 4g / L, hydrogen peroxide stabilizer 8g / L, chelating dispersant 8g / L, and the rest are the same.

[0037] (4) Soft finishing: bulking agent 15g / L, triethanolamine 15g / L, setting temperature 150°C, vehicle speed 40 m / min.

[0038] (5) Napping: The front napping method is as follows: the speed of the clockwise roller is 200 rpm, and the pressure of the clockwise roller is 0.1Mpa; The cylinder speed is 80 rpm, the cloth feeding speed is 15 m / min, and the tension of the cloth guide roller is 2.0%. The method of napping on the reverse side is: the rotation...

Embodiment 3

[0043] On the basis of Example 1, the difference from Example 1 is: Gray fabric specification: 106" / 40s*40s / 133*72, 70% cotton 30% tencel, 1 / 2 twill, weft surface coverage rate is 66% .

[0044] The difference in method steps (1)~(8) is:

[0045] (1) The speed of singeing is 110 m / min.

[0046] (2) Enzyme desizing: amylase 5g / L, stack at 50°C for 8h.

[0047] (3) Rebleaching: 100% hydrogen peroxide 6g / L, hydrogen peroxide stabilizer 10g / L, chelating dispersant 10g / L.

[0048] (4) Soft finishing: fluffing agent 20g / L, glycerol 5g / L, urea 10g / L, setting temperature 130°C, vehicle speed 30 m / min.

[0049] (5) Napping: The front napping method is as follows: the speed of the clockwise roller is 250 rpm, and the pressure of the clockwise roller is 0.15Mpa; The cylinder speed is 90 rpm, the cloth feeding speed is 25 m / min, and the tension of the cloth guide roller is 2.5%. The method of napping on the reverse side is: the rotation speed of the clockwise roller is 500 rpm, and t...

Abstract

The invention discloses a method for processing a cotton tencel double-faced fleece fabric with improved fluff uniformity, which comprises the following steps: the cotton tencel blended yarn fabric is singed, enzyme desizing, rebleaching, soft finishing, napping, and humidification Shearing, drying and shearing, printing or dyeing, and post-finishing process, the cotton tencel double-faced fleece fabric is obtained. In the humidification and shearing process, steam box or atomization method is used to humidify the cloth surface. The covering rate of the weft yarn on the surface of the fabric is 66% to 88%, and the moisture content of the cloth surface after humidification in the humidification and shearing process is 80% to 90%. The cotton and tencel blended yarn fabric of the present invention has good fluff uniformity, and the fabric has a very good appearance after washing. After washing, the fluff is not clustered and messy, and has a plump wool feeling, and at the same time, the strength of the fluff is not damaged. .

Description

technical field [0001] The invention relates to a processing method of a fabric, in particular to a processing method of a cotton tencel double-faced fleece fabric which improves the uniformity of the fluff. Background technique [0002] Tencel is a kind of regenerated cellulose fiber with high strength, hygroscopicity and expansibility. The surface of the fiber is relatively smooth. Its cross section is round or oval with soft luster. The fabric made of Tencel has soft hand feeling, good drapability, good airiness, and high skin-friendliness. Cotton fiber is a kind of natural cellulose fiber, which also has the characteristics of cellulose fiber. However, all cotton fabrics also have certain shortcomings, such as the fabric is easy to wrinkle, the luster of all cotton velvet fabrics is dull, and the hand feels hard. Therefore, the cotton-tencel blended yarn fabric formed by blending cotton fiber with tencel can improve the handle, luster and drape of the fabric. [0003]...
