Production process of twice grained cloth

Abstract

The production process of twice grained cloth includes the following steps: mixing PE, EVA, PEVA or other polyolefin material and coloring material inside a stirrer; heating and extruding the mixture in a screw extruder with heating assembly to a T-shaped mold to form plastic cloth; cooling; rolling the plastic cloth with roller with surface stereo grains and inside heating assembly while heating the surface of the plastic cloth to form grains; and re-cooling to obtain environment friendly plastic cloth with surface stereo grains and of PE, EVA, PEVA or other polyolefin material.

Description

technical field [0001] The invention provides a method for manufacturing a secondary embossed cloth (including plastic cloth or plastic film), especially a method made of polyethylene (Polyethylene, referred to as PE), ethylene vinyl acetate copolymer (Ethylene Vinylacetate, referred to as EVA) or A manufacturing method in which three-dimensional reliefs are continuously produced on the surface of a plastic cloth or plastic film made of plasticized materials such as polyethylene vinyl acetate (PEVA for short). Background technique [0002] Generally speaking, most of the problems of environmental protection come from various plastic products. These plastic products are widely used in various industries such as electronics, information, communication, optoelectronics, medical equipment and daily necessities, resulting in a large amount of plastic waste. It can decompose in the natural environment or garbage dump, and can resolve toxic substances, causing serious pollution to ...

AI Technical Summary

Problems solved by technology

But when making PE, EVA or PEVA plastic cloth with this kind of traditional method, because of the characteristic of PE, EVA or PEVA material, cause the three-dimensional embossing on it to become blurred, and when rolling three-dimensional embossing, to The continuous strength of PE, EVA or PEVA plastic cloth will cause damage, resulting in the embossed plastic cloth made of discontinuous or uneven strength, which is easy to be torn at the embossed position
