Problems solved by technology

The existing leather base cloth production process, for example, discloses "a kind of elastic leather base cloth and its preparation method" in the Chinese invention patent with the notification number CN102168339B. The gray cloth is formed by blending, and the gray cloth is desized, scoured, dyed, After fluffing and shaping, a leather base cloth is produced, but the existing process has many processes and low production efficiency, and secondly, the gray cloth is seriously polluted to the environment in the dyeing process, and the production cost is relatively high

Embodiment 1

[0042] A production process of high elastic leather base cloth, comprising the following steps:

[0043] 1. Preparation of raw material colored silk

[0044] The preparation method of raw material color silk comprises the following steps:

[0045] 1) Use PET slices for vacuum drying, the drying temperature is controlled at 155°C, and the moisture content of the dried PET slices is ≤0.0025%;

[0046] 2) The dried PET chips and masterbatch are mixed in a certain proportion and put into the screw extruder for melting, and the melting temperature is controlled between 290°C and 295°C;

[0047]3) Put the extruded dyed yarn into the spinning box, and carry out spinning process through the spinneret, and the temperature in the spinning box is controlled between 290°C and 295°C;

[0048] 4) Cool the colored yarn after spinning, and the surface temperature of the colored yarn drops to 50°C;

[0049] 5) Carry out oiling operation on the surface of colored silk;

[0050] 6) Take 3500...

Embodiment 2

[0077] A production process of high-elastic leather base cloth, the difference from Example 1 is that the drying temperature is controlled at 168°C, the surface temperature of the colored yarn is reduced to 50°C; the temperature of the shaping hot box is controlled at 125°C, and the draft ratio is 1.2 , the temperature of the colored yarn drops to 59°C under the action of the cooling plate, and the oil content of the colored yarn is controlled at 2.7% after passing through the oiling system; the density of the gray cloth obtained after weaving by the circular loom is 14 mesh; The width ratio is 0.8, the shrinkage ratio of the second napping is 0.74, and the shrinkage ratio of the third napping is 0.73; the drying room is controlled at 220°C, and the ratio of the entrance width to the exit width of the drying room track is 0.53. It forms an included angle of 0.8° with the advancing direction of the napped cloth.

Embodiment 3

[0079] A production process of high-elastic leather base cloth, the difference from Example 1 is that the drying temperature is controlled at 160°C, the surface temperature of the colored thread is dropped to 45°C, and the colored thread is wound up with 3600 meters as a roll; the deformation heat The temperature of the box is controlled at 180°C, the temperature of the shaping hot box is controlled at 123°C, the draft ratio is 1.18, the temperature of the colored yarn drops to 57°C under the action of the cooling plate, and the oil content of the colored yarn is controlled at 2.5 after passing through the oiling system %; the gray cloth density obtained after circular loom weaving is 13 meshes; the shrinkage ratio of the control gray cloth in the pre-napping is 0.77, the shrinkage ratio of the second napping is 0.72, and the shrinkage ratio of the third napping is 0.68; The drying room is controlled at 200°C, the chain transmission speed is 85 yards, the ratio of the entrance ...

Abstract

The invention discloses a manufacturing process of gauze with high flexibility. The manufacturing process, which has managed to simplify technical procedures, improve production efficiency and decrease environmental pollution on the premise of producing gauze with high flexibility, comprises preparation of raw material for dyed yarn, enhancement of flexibility, weaving, napping, sizing and packaging .

Description

technical field [0001] The invention relates to a production process of imitation leather, in particular to a production process of leather base cloth. Background technique [0002] With the continuous improvement of living standards, people's requirements for clothing fabrics are also getting higher and higher. Those textile fabrics with bright colors, soft touch, good drape and resilience are favored by consumers. As the backsheet of artificial leather, leather base fabric has good elasticity, high tensile strength and relatively smooth surface flatness, so it is favored. The existing leather base cloth production process, for example, discloses "a kind of elastic leather base cloth and its preparation method" in the Chinese invention patent with the notification number CN102168339B. The gray cloth is formed by blending, and the gray cloth is desized, scoured, dyed, A leather base cloth is made after fluffing and setting, but the existing technology has many processes and...
