Embodiment 2

[0045] Fabric specification: BCM40*BCPT40*165*95*57 / 58, weave: 4 / 1 satin.

[0046] The above-mentioned pure cotton fabric is treated by the above-mentioned high-efficiency short-flow formaldehyde-free non-ironing process. The steps are: cold stacking-washing and bleaching-mercerizing-liquid ammonia-steam whitening-tentering. The main process is as follows:

[0047] 1) Cold pile process: NaOH: 35g / L, H 2 o 2 : 20g / L, cold stack chelating agent MAG: 15g / L, stacking time: 16h.

[0048] 2) Washing and bleaching: refining agent SA-U: 6g / L, chelating agent SQ-A: 4g / L, hydrogen peroxide stabilizer 266: 4g / L, hydrogen peroxide: 5g / L, caustic soda: 2g / L, vehicle speed: 80m / L min, stack cloth at 100°C for 15 minutes in a steamer;

[0049] 3) Mercerizing process: caustic soda concentration 170g / L, light alkali concentration 5g / L, vehicle speed 70m / min;

[0050] 4) Liquid ammonia process: liquid ammonia treatment chamber temperature 65°C, steam temperature 110°C, vehicle speed 60m / min...

Embodiment 3

[0063] Fabric specification: CM80 / 2*CM80 / 2*160*90*57 / 58, weave: CP.

[0064] The above-mentioned pure cotton fabrics are treated by using the high-efficiency short-process formaldehyde-free non-ironing process technology. The steps are: cold stacking-washing and bleaching-mercerizing-liquid ammonia-steam whitening-tentering. The main process is as follows:

[0065] 1) Cold pile process: NaOH: 25g / L, H 2 o 2 : 17g / L, cold stack chelating agent MAG: 20g / L, stacking time: 20h.

[0066] 2) Washing and bleaching: refining agent SA-U: 6g / L, chelating agent SQ-A: 6g / L, hydrogen peroxide stabilizer 266: 4g / L, hydrogen peroxide: 6g / L, caustic soda: 2g / L, vehicle speed: 80m / min, stack cloth at 100°C for 15 minutes in a steamer;

[0067] 3) Mercerizing process: caustic soda concentration 160g / L, light alkali concentration 5g / L, vehicle speed 70m / min;

[0068] 4) Liquid ammonia process: liquid ammonia treatment chamber temperature 65°C, steam temperature 110°C, vehicle speed 60m / min;...

Abstract

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to an efficient short-process formaldehyde-free non-ironing process. The process adopts the following processing flow of cold batch, water washing bleaching, mercerizing, liquid ammonia treating, steaming whitening and tentering. In the formaldehyde-free non-ironing process, any magnesium chlorideor inorganic salt catalyst is not needed for matching, and the crease resistance is 3.2 grade. By means of the method disclosed by the invention, the finishing process flow is short, a fabric is endowed with excellent crease resistance by using environment-friendly formaldehyde-free resin, the whiteness is lasting and bright, and the extremely high wearing serviceability is achieved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to an efficient short-flow formaldehyde-free non-ironing process. Background technique [0002] In the current technological life, the concept of green, environmentally friendly and healthy life is deeply rooted in the hearts of the people. Clothing is safe and environmentally friendly, anti-wrinkle, and easy to care for many white-collar and high-end business consumers. With the continuous improvement of consumer demand for fabric quality, Non-ironing products have been extended from conventional formaldehyde-free ironing, low-formaldehyde-free ironing, to formaldehyde-free ironing-free. However, the anti-wrinkle performance of formaldehyde-free non-ironing fabrics on the market can only reach about 2.5 grades, and the processing process is long, and the energy consumption loss is large. The anti-wrinkle performance cannot meet the needs of consumers...
