Problems solved by technology

However, this process adopts the color fixing method of adding baking soda and urea to the printing paste, and the discharged sewage contains a large amount of ammonia nitrogen substances, which is poor in environmental friendliness, and its performance is greatly reduced after being washed several times, and the quick-drying effect is obvious. decline

Embodiment 1

[0059] In the printing process, when mixing pulp, first mix the disperse dyes with cold water, add the paste and stir evenly, then add the reactive dye solution and stir evenly, and at the same time add anti-dyeing salt to prevent the dye from being reduced and discolored during steaming.

[0060] The baking temperature is controlled at 205-215°C, and the baking time is 2-4 minutes, so the fiber and color paste absorb more moisture and swell better, which is conducive to the diffusion of disperse dyes into the fiber, and the slurry is easy to wash off when washing with water.

[0061] Use a fast steamer to fix the color, and the cloth speed of the steamer is controlled at 15-60 m / min. In the case of changes in the steam intake, cloth type, and liquid volume, the temperature is controlled by adjusting the amount of steam entering the steamer. The total heat is for heat balance. The steaming formula is: caustic soda 22g / l, soda ash 148g / l, sodium chloride 98g / l, potassium carbona...

Embodiment 2

[0064] Repeat the same steps as described in Example 1, the baking temperature is 210°C, and the baking time is 3 minutes; the steaming formula is: caustic soda 25g / l, soda ash 150g / l, sodium chloride 100g / l, potassium carbonate 100g / l, the steaming washing temperature is 135°C; the finishing liquid formula is: moisture absorption quick-drying agent 60g / l, fixing agent 20g / l, penetrating agent 2g / l.

Embodiment 3

[0066] Repeat the same steps as described in Example 1, the baking temperature is 215°C, and the baking time is 4 minutes; the steaming formula is: caustic soda 27g / l, soda ash 153g / l, sodium chloride 103g / l, potassium carbonate 105g / l, the steaming washing temperature is 137°C; the finishing liquid formula is: 65g / l of moisture-absorbing quick-drying agent, 24g / l of fixing agent, and 3g / l of penetrating agent.

[0067] After the above processes, the fabric samples were taken out for testing.

[0068]

[0069] The basic safety technical indicators are inspected according to the test method specified in GB18401-2010.

[0070] The breaking strength shall be carried out according to GB / T 3923.1-1997: take the sample after the whole dyeing and finishing process, take a 30cm*6cm strip sample, five warps and five wefts, remove the yarn on the long side of the strip sample, so that the long side of the strip sample is continuously contained Yarn, and the effective length of the ...

Abstract

The present invention discloses a polyester / cotton interwoven fabric dyeing and fishing process, which comprises cold stacking, washing and blanching, shaping, mercerizing, ammonia nitrogen emission-free environmental-protection type dispersing reactive printing, persistent moisture absorption and sweat releasing finishing, and stentering and anti-shrinking treating. According to the present invention, in the ammonia nitrogen emission-free environmental-protection type dispersing reactive printing, the color fixation method that baking soda and urea are added to a printing slurry after printing drying in the traditional process are abandoned, only a dye, a paste and other materials are added to a printing slurry, an alkali agent and gravy salt rapid steam color fixation method is adopted after printing drying to make color fixation of a reactive dye, the whole process does not adopt urea as the additive, no ammonia nitrogen exists in the discharged water, and characteristics of environmental protection and energy saving are provided; and the persistent moisture absorption and sweat releasing finishing process adopts a nano-scale moisture absorption rapid drying agent and a washing resistance fixing agent, and the used additives and fibers are subjected to cross-linking after high temperature baking so as to significantly increase function persistence.

Description

technical field [0001] The invention belongs to the field of printing and dyeing technology, more specifically, the invention relates to a dyeing and finishing technology of polyester-cotton interwoven fabric. Background technique [0002] The advantage of polyester and long-staple cotton interwoven fabric is that it not only has the characteristics of high strength, high wear resistance, high heat resistance, and high corrosion resistance of polyester, but also has long-staple cotton, which is thin and long in length, moisture-absorbing, breathable, and comfortable. Cooling, heat dissipation and other functions, it is a rare blended product in the market in recent years. Chinese Patent No. CN200710113014.4 discloses a dyeing and finishing process of polyester-cotton warp and weft yarn-wrapped polyolefin elastic fiber fabrics, which belongs to a processing technique for elastic fabrics. Wool, desizing, mercerizing, setting, dyeing, finishing, pre-shrinking. In this dyeing...
