Embodiment 1

[0100] A method for producing fluorine-free anti-siphon high-density synthetic leather, comprising:

[0101] S1. The non-woven fabric is unrolled through the cloth storage rack, and the unrolled non-woven fabric enters the impregnation tank for impregnation. After impregnation, it enters the pre-solidification tank for pre-solidification; the pre-solidified non-woven fabric is ironed by the ironing device Processing, and then through the coating table device equipped with a coating knife for fabric scraping treatment.

[0102] In the step S1, the thickness of the non-woven fabric is 0.65mm, and the grammage is 195g / m 2 , blasting is 17kgf / cm 2 ; Tensile strength > 120N in warp direction, > 70N in weft direction; elongation at break > 80% in warp direction, and > 170% in weft direction. Before the non-woven fabric is unrolled, the non-woven fabric is subjected to water-repellent treatment with a water-based waterproof agent, and the non-woven fabric after the waterproof treat...

Embodiment 2

[0108] A method for producing fluorine-free anti-siphon high-density synthetic leather, comprising:

[0109] S1. The non-woven fabric is unrolled through the cloth storage rack, and the unrolled non-woven fabric enters the impregnation tank for impregnation. After impregnation, it enters the pre-solidification tank for pre-solidification; the pre-solidified non-woven fabric is ironed by the ironing device Processing, and then through the coating table device equipped with a coating knife for fabric scraping treatment.

[0110] In the step S1, the thickness of the non-woven fabric is 0.70mm, and the grammage is 200g / m 2 , blasting is 17kgf / cm 2 ; Tensile strength > 120N in warp direction, > 70N in weft direction; elongation at break > 80% in warp direction, and > 170% in weft direction. Before the non-woven fabric is unrolled, the non-woven fabric is subjected to water-repellent treatment with a water-based waterproof agent, and the non-woven fabric after the waterproof treat...

Embodiment 3

[0116] A method for producing fluorine-free anti-siphon high-density synthetic leather, comprising:

[0117] S1. The non-woven fabric is unrolled through the cloth storage rack, and the unrolled non-woven fabric enters the impregnation tank for impregnation. After impregnation, it enters the pre-solidification tank for pre-solidification; the pre-solidified non-woven fabric is ironed by the ironing device treatment, and then through the coating table device equipped with a coating knife for fabric scraping treatment.

[0118] In the step S1, the thickness of the non-woven fabric is 0.75mm, and the grammage is 205g / m 2 , blasting is 17kgf / cm 2 ; Tensile strength > 120N in warp direction, > 70N in weft direction; elongation at break > 80% in warp direction, and > 170% in weft direction. Before the non-woven fabric is unrolled, the non-woven fabric is subjected to water-repellent treatment with a water-based waterproof agent, and the non-woven fabric after the waterproof treatm...

Abstract

The invention provides a fluorine-free anti-siphon high-density synthetic leather and a production method thereof. The method comprises the steps of that a non-woven fabric is unwinded through a clothstorage rack, the unwinding non-woven fabric enters into a soaking tank for soaking, and then enters a pre-coagulation tank for pre-coagulation after immersion; the pre-coagulated non-woven fabric isironed by an ironing device, and then the fabric is scraped by a coating device equipped with a coating knife; the non-woven fabric coated with the fabric is firstly coagulated in a triple fold coagulation tank to generate synthetic leather; the synthetic leather from the triple fold coagulation tank is washed in a water washing tank to obtain bass; the bass from the washing tank is pre-ironed byan ironing roller and then dried in the oven, and the dried bass is rolled up. The method has the advantages of having fluorine content meeting the environmental protection requirements, not causingharm to human health; good siphon prevention effect, and high stripping data; and full hand feeling and good rebound property of the bass.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a fluorine-free anti-siphon high-density synthetic leather and a production method thereof. Background technique [0002] Synthetic leather products are used in all aspects of our lives, and their product functions are also rich and colorful. In recent years, waterproof synthetic leather materials have become more and more popular, especially for more and more types of shoes. People have also been experimenting on how to make casual shoes, sports shoes, etc. that are usually worn have the same waterproof effect as water shoes. At present, there are more and more shoes with waterproof effect on the market, but their stability and environmental protection are still not up to the requirements; and many waterproof materials are added with fluorine-based waterproofing agent, although the waterproof effect of fluorine-based waterproofing agent Very good, but fluorine is a substance h...
