Problems solved by technology

However, if the genuine leather is made as thin as nylon silk, pure cotton, and polyester-cotton fabric, its strength cannot meet the requirements of down jacket fabrics, and high-grade artificial leather (PU leather) can be made as thin as nylon silk, pure cotton, and polyester-cotton fabric. Thin, its strength is no problem, but the basic base fabric is still made of pure cotton, polyester-cotton gray cloth, the defect is that leather products are generally still thick, the leather products made have certain limitations, especially not suitable for down jacket fabric

[0036] Such as figure 1 As shown, the present invention uses fine denier yarns as warp and weft yarns to woven into fine denier grey fabrics. The grey fabrics are dyed and finished to obtain a leather base fabric. The thickness of the leather base fabric 1 is 0.12 mm. Cashmere 2. The fine denier yarn is a fine denier polyester yarn, and the specification of the fine denier polyester yarn is 50D144F.

[0037] The preparation method includes the following steps:

[0038] (1) Desizing, scouring and dyeing are carried out with a flat-width jigger, and the temperature of desizing, scouring and dyeing is 90

[0039] ±2℃, the speed is 95±2m / min;

[0040] (2) Desizing method selection: using biological enzyme for desizing, biological enzyme preparation is medium temperature α-amylase, desizing

[0041] The ratio of each substance in the water is: 4g of medium temperature α-amylase and 4g of salt per liter of water;

[0042] (3) Raising: Raising with imported raising machine, model: 92067-R209...

Embodiment 2

[0045] In the present invention, fine denier yarns are used as warp yarns and weft yarns to be woven into a fine denier grey fabric. The grey fabric is dyed and finished to obtain a leather base fabric. The thickness of the leather base fabric is 0.12 mm, and one side of the leather base fabric is provided with fleece. The fine denier yarn is a fine denier nylon yarn, and the specification of the fine denier nylon yarn is 50D144F.

[0046] The preparation method includes the following steps:

[0047] (1) Desizing, scouring and dyeing are carried out with a flat-width jigger, and the temperature of desizing, scouring and dyeing is 90

[0049] (2) Desizing method selection: using biological enzyme for desizing, biological enzyme preparation is medium temperature α-amylase, desizing

[0050] The ratio of each substance in the water is: 5g of medium temperature α-amylase and 5g of salt per liter of water;

[0051] (3) Raising: Raising with imported rais...

Embodiment 3

[0054] In the present invention, fine denier yarns are used as warp yarns and weft yarns to be woven into a fine denier yarn grey fabric. The grey fabric is dyed and finished to obtain a leather base fabric, the thickness of the leather base fabric is 0.08mm, and both sides of the leather base fabric are provided with fleece. The fine denier yarn is fine denier polyester yarn.

[0055] The preparation method includes the following steps:

[0056] (1) Desizing, scouring and dyeing are carried out with a flat-width jigger, and the temperature of desizing, scouring and dyeing is 90

[0057] ±2℃, the speed is 95±2m / min;

[0058] (2) Desizing method selection: using biological enzyme for desizing, biological enzyme preparation is medium temperature α-amylase, desizing

[0059] The proportion of each substance in the water is as follows: each liter of water contains 7g of medium temperature α-amylase and 7g of salt;

[0060] (3) Raising: Raising with imported raising machine, model: 92067-R20...

Abstract

The invention discloses a fine denier yarn leather base fabric and a preparation method thereof. In the leather base fabric, fine denier yarn grey cloth is weaved by using fine denier yarns warps and wefts, and the leather base fabric with the thickness below 0.15mm is prepared by dyeing and finishing the grey cloth. The preparation method comprises the following steps of: (1) desizing, scouring and dyeing by adopting a full width jig dyeing machine, wherein the temperature for desizing, scouring and dyeing is 90+ / -2 DEG C, and the velocity for desizing, scouring and dyeing is 95+ / -2m / min; (2) selecting a desizing mode: bio-enyzme desizing is adopted, wherein a bio-enzyme preparation is intermediate temperature alpha-amylase, the proportion of the substances in desizing is as follows: 2 to 10g of intermediate temperature alpha-amylase and 2 to 10g of salt are contained in water per liter; (3) raising: raising is realized by an imported raising machine the model of which is 92067-R2094; and (4) shaping the finished product: the shaping temperature is controlled within a range from 180 to 185 DEG C, and the shaping time is controlled within a range from 35 to 45 seconds.

Description

technical field [0001] The invention relates to the field of textiles, in particular to basic base fabrics for leather products such as artificial leather. Background technique [0002] Leather base fabric is the basic base fabric used to make artificial leather. With the improvement of people's living standards, the demand for leather clothing is increasing. The number of natural leather is far from meeting people's needs, and natural leather is expensive. The price is too high, and the ordinary working class is discouraged. Therefore, high-quality and low-cost artificial leather has emerged as the times require. [0003] Artificial leather has entered the Chinese market for decades. With the development of artificial leather technology, high-grade artificial leather (PU leather) has completely replaced genuine leather products and is widely used in shoe leather, bag leather, sofa leather, etc. In addition to the characteristics of hand feel and breathability, it also has ...
