Embodiment 1

[0021] 1) Send the collagen fiber into the opener to open the collagen fiber bundle, and mix the collagen fiber bundle, the speed of the opening roller is 1650 rpm;

[0022] Apply an antistatic agent to the collagen fiber bundles to reduce the static electricity of the collagen fibers and improve problems such as roll wrapping and web sticking during the carding process. The amount of antistatic agent is 1.2% of the weight of the collagen fibers;

[0023] Comb the collagen fiber bundles into a single state to form a uniform collagen fiber network. The output speed of the carding machine is controlled at 32 m / min, the cylinder speed is controlled at 440 m / min, and the doffer line speed is controlled at 28 m / min. The roller speed is controlled at 43 m / min, and the stripping roller speed is controlled at 110 m / min;

[0024] The combed collagen fiber web becomes disorderly arrangement through the action of airflow, and forms a higher grammage collagen fiber web. During the air-fo...

Embodiment 2

[0030] 1) Send the collagen fiber into the opener to open the collagen fiber bundle, and mix the collagen fiber bundle, the speed of the opening roller is 1900 rpm;

[0031] Apply an antistatic agent to the collagen fiber bundles to reduce the static electricity of the collagen fibers and improve problems such as winding rolls and web sticking during the carding process. The amount of antistatic agent is 2% of the weight of the collagen fibers;

[0032] Due to the poor uniformity and large difference in fineness of the collagen fibers, it is easy to reduce the speed of the carding machine. The collagen fiber bundles are combed into a single state to form a uniform collagen fiber network. The speed of the net is controlled at 48 m / min, and the cylinder speed is controlled At 480 m / min, the doffer line speed is controlled at 35 m / min, the work roll speed is controlled at 52 m / min, and the stripping roller speed is controlled at 110 m / min;

Abstract

At present, the synthetic leathers are made of artificial fibers, and due to the performance difference between the artificial fibers and real leather collagen fibers, the performances of the artificial leathers are greatly different from the performances of the real leathers. The existing reclaimed leathers have harder handfeel and the environment is polluted in the production processes of the reclaimed leathers. The invention provides a method for producing an artificial leather base material by compounding collagen fibers by utilizing spun-laced water jetting. The method comprises the following steps: 1) firstly preparing the collagen fibers into a collagen fiber sheet for compounding by utilizing spun-laced water jetting; and 2) opening and entangling the collagen fiber sheet by utilizing spun-laced water jetting in a spun-laced nonwoven process, at the same time, compounding the collagen fiber sheet with an opened and carded synthetic fiber sheet, and after compounding, implanting the synthetic fibers in the collagen fibers so that the two different fiber sheets are firmly bonded as a whole. The method has the following beneficial effects: after undergoing the subsequent coating processing, the obtained base material has stronger leather feel and better simulation than the traditional synthetic leathers and softer handfeel than the reclaimed leathers; and the method is more environment-friendly than the traditional production methods of the reclaimed leathers.

Description

technical field [0001] The invention relates to the processing technology of artificial leather, in particular to a method for compounding collagen fiber net and synthetic fiber net into artificial leather base material by using the hydroentanglement jet flow of the hydroentanglement non-woven process. Background technique [0002] At present, there are two types of leather products popular in the market: genuine leather and artificial leather. Genuine leather is made from animal skins such as cattle and sheep through a complex tanning process. Leather tanning is to use tannin to chemically and physically process the protein in the skin. It uses a series of processes and uses some chemical agents to make a series of changes in the protein in the raw hide of cattle, pigs, sheep and other animals to make collagen Denaturation occurs. The tanned leather is soft, firm and wear-resistant, and it is not easy to rot and deteriorate. Therefore, the tanned leather can be used to m...
