How to identify non-woven bags? First of all, we need to know that the material of non-woven environmental protection bags is naturally non-woven, also called non-woven fabric. But we generally call it non-woven fabric. There are many types of non-woven fabrics in today's non-woven market. There are new materials, ordinary materials, film materials. And if you only observe from the vision of the eye, you can basically only distinguish between coated and uncoated materials. It is visually impossible to tell whether it is completely new or ordinary.
In order to save costs, many businesses use ordinary materials as new materials to process non-woven environmentally friendly bags for customers. What is to be said here is the difference between brand new materials and ordinary materials. What is a brand new material? In other words, in the process of raw material processing, non-woven fabrics without adding any recycled materials are called brand new materials. What is ordinary material? It is to add a certain amount of recycled material in proportion during the processing of raw materials, and the recycled material referred to here is also used non-woven fabrics. Most of them are recycled in non-woven environmental protection bag manufacturers. Cut corners of the bag while cutting. Therefore, ordinary materials are generally cheaper than new materials.
Secondly, in order to be able to discern from the non-woven fabric whether it is a brand new material, we can feel the type of the fabric from the feel. Today's ordinary fabrics on the market are relatively stiff, while new fabrics are relatively soft. The difference between them is that the feel of the new material is much softer, closer to the real knitted fabric, and the toughness of the fabric is better than ordinary materials, the tensile force is stronger, and it is not easy to tear. But there is one point. The same weight fabric, the new material feels thinner than ordinary materials. In fact, it is just an illusion.
The texture of ordinary materials feels harder to the touch, a bit like the texture of paper. And the same gram weight of cloth, ordinary materials must be thick, because the non-woven fabric is also made of plastic pellets, if the fabric is too hard, it will lose the flexibility and strong tensile strength Sex. And this method is also a common practice of many bad businesses to cut corners.
