Problems solved by technology

At present, when this kind of composite fabric is processed, the two are mostly bonded together by glue, but the use of a large amount of glue will not only increase the composition, but also endanger people’s health. Therefore, people try to heat the two materials to reach the softening temperature. Then press the non-glue bonding method, although it is technically feasible, but usually the processed composite fabric is easy to crack, and the bonding strength between the two is not high

Abstract

The invention discloses a PVC (polyvinyl chloride) and nonwoven fabric glue-free bonding process, and relates to a PVC and nonwoven fabric processing method. The process specifically comprises the following steps: (1) preheating a nonwoven fabric; (2) preheating PVC; (3) pressing; and (4) modifying. The composite cloth prepared by the method has the characteristics of favorable appearance, excellent corruption resistance and oxidation resistance, high binding strength and stable use quality.

Description

technical field [0001] The invention relates to a processing method of PVC and non-woven fabric, in particular to a non-glue bonding process of PVC and non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. [0003] PVC material is widely used because of its good thermal insulation performance, good sound insulation performance and light weight. It is a common raw material for home decoration like non-woven fabrics. In order to obtain materials with better performance, people combine non-woven fabrics and PVC material...
