Embodiment 1

[0011] Example 1: The warp yarn is made of full-dull FDY22.2dtex / 24f nylon filament, and the sizing is done. The weft yarn adopts full-dull FDY22.2dtex / 24f nylon filament. According to the requirements of warp density of 770 threads / 10cm, weft density of 740 threads / 10cm, total warp threads of 12,474, width of 162cm, and grammage of 55g / m, plain weave is woven on Tsudakoma series water-jet looms. Then the woven gray cloth is unrolled, stitched, pre-desized, pre-set, dyed, fixed, dehydrated, opened, finished, calendered, inspected, coded, and packaged, including untwisting, one-time feeding, and stacking. Placement, primary water washing, secondary feeding, steaming, secondary water washing, drying and other processes for production, wherein the cold stacking method and high-efficiency open-width desizing and water washing method are adopted in the desizing pretreatment step, in the cold stacking method The composition of the working fluid is: liquid caustic soda 100g / L, degre...

Embodiment 2

[0012] Embodiment 2: processing step is with embodiment 1. Among them, the composition of the working fluid in the cold stack method is: liquid caustic soda 95g / L, degreasing agent TF-115C4g / L, four-in-one refining agent TF-1704.5g / L, under the conditions of liquid entrainment rate of 28% and temperature of 22°C Under treatment for 30h; the composition of the working fluid in the high-efficiency open-width desizing and washing method is: oxidation desizing agent TF-127K4.2g / L, chelating dispersant TF-133A1.5g / L, degreasing agent TF-1261.7 g / L, liquid caustic soda 17g / L, open-width desizing and water washing under the conditions of temperature 96°C and machine speed 75m / min.

Embodiment 3

[0013] Embodiment 3: processing step is with embodiment 1. Among them, the composition of the working fluid in the cold stack method is: liquid caustic soda 105g / L, degreasing agent TF-115C5.5g / L, four-in-one refining agent TF-1706g / L. Treated under conditions for 39h; the composition of the working liquid in the high-efficiency open-width desizing and washing method is: oxidation desizing agent TF-127K5.8g / L, chelating dispersant TF-133A2.3g / L, degreasing agent TF- 1262.5g / L, liquid caustic soda 22g / L, open-width desizing and water washing under the conditions of temperature 100°C and machine speed 83m / min.

Abstract

The invention discloses a desizing pretreatment method for high-density nylon fabric. The desizing pretreatment method comprises two steps including a cold heaping procedure, and an efficient open-width desizing and washing procedure, wherein a working solution used in the cold heaping procedure comprises the components of caustic soda liquid, a degreaser TF-115C, and a four-in-one refining agent TF-170 which are processed for 30-39 hours under the conditions that the liquid containing rate is 28-31% and the temperature is 22-25 DEG C; and a working solution used in the efficient open-width desizing and washing procedure comprises the components of an oxidation desizing agent TF-127K, a sequestering agent TF-133A, a degreaser TF-126 and caustic soda liquid, and the open-width desizing and washing can be carried out under the conditions that the temperature is 96-100 DEG C and the machine speed is 75-83m / min. The desizing pretreatment method has the advantages that the treatment can be carried out at normal temperature by a reasonable design and allocation of each auxiliary component of the working solution in the cold heaping and desizing washing procedures; the damage to fiber is small; the dyeing reproducibility and the primary success rate can be obviously improved; and the technical problems of high energy consumption, large loss of the fabric, and difficult guarantee on subsequent dyeing quality caused by an unreasonable pretreatment process of the common nylon fabric are well solved.

Description

technical field [0001] The invention belongs to the technical field of fabric treatment technology, and in particular relates to a desizing pretreatment method for high-density nylon fabrics. Background technique [0002] The textile printing and dyeing industry has always been an industry with high energy consumption and high pollution. According to statistics, the coal consumption per 10,000 meters of cloth in my country is about 3 tons, the power consumption is 450KW / hour, the water consumption is 300-400 tons, and the energy consumption is 3 to 5 times the international advanced level, the water consumption is 2 to 3 times. With the country's increasing environmental protection efforts and the arrival of low-carbon economy, how to develop energy-saving and consumption-reducing processes has become the top priority for printing and dyeing enterprises. At the same time, with the continuous improvement of people's living standards, consumers have higher and higher requireme...
