Embodiment Construction

[0010] The manufacture method of this fiber composite sheet is that the fiber composite sheet is formed by laminating the fiber body and the high molecular elastic body, the described fiber body is bundled nylon superfine fiber, and the high molecular elastic body is Polyurethane resin, the polymer elastic body has an infrared absorber to enhance the function of absorbing infrared laser and improve the drilling effect; after lamination, the composite sheet is scanned by a pulse laser through a high-speed scanning galvanometer, and the high-speed scanning During the scanning process of the galvanometer, its pulse laser keeps emitting light. The pulse frequency of the pulse laser is greater than 10KHZ. The scanning speed of the high-speed scanning galvanometer matches the pulse frequency of the pulse laser, so that the composite sheet After scanning, discrete micropores are obtained. The pulsed laser generates infrared laser with a laser wavelength of 0.76-14 μm. The microhole ...

Abstract

The invention discloses a manufacturing method of a fiber composite sheet, which is characterized in that the fiber composite sheet is made of a fibrous body and a polymer elastic body by lamination. After the lamination, the composite sheet is scanned by a high speed scanning vibration mirror using a pulse laser, the pulse laser is kept in a light emitting state in the scanning process of the high speed scanning vibration mirror; and the scanning speed of the high speed scanning vibration mirror is matched with the pulse frequency of the pulse laser, making the composite sheet get discrete micro-pores after scanning. The fiber composite sheet made using the manufacturing method has even apertures of pores made on the polymer elastic body, and air permeability performance and moisture absorption are controlled by adjusting density and size of the pores to meet the requirements of different purposes. The manufacturing method is applicable to linings, cloths and shoe leather for replacing natural leather.

Description

technical field [0001] The present invention relates to a manufacturing method of a fiber composite sheet suitable for use as a substitute for natural leather, and in particular relates to a manufacturing method of using a laser to open holes on a fiber composite sheet product. Background technique [0002] In recent years, due to the large pollution and high cost of natural leather manufacturing industry, it has been restricted. Therefore, as a substitute for natural leather, the fiber composite sheet obtained by laminating a sheet composed of a polymer elastomer on the surface of a substrate mainly composed of fiber aggregates has the characteristics of light weight, non-ironing, and low price. , It is widely used in clothing and shoes. In the application process of these fields, in order to make its performance better, this fiber composite sheet is generally made into a sheet that is both breathable and water-permeable. Since the fiber aggregate itself is a breathable an...
