How to identify non-woven environmental protection bag fabric?

How to identify non-woven environmental protection bag fabric? First of all, we need to know that the material of the non-woven environmental protection bag is naturally non-woven fabric, also known as non-woven fabric. However, we generally call it non-woven fabric. There are many kinds of non-woven fabrics in today's non-woven fabric market. There are new materials, common materials, film covering materials, etc. However, if we only observe from the eye's vision, we can only distinguish between film-covered and non-film-covered materials. Visually, it is impossible to tell whether it is a new material or a common material. In order to save costs, many merchants will use ordinary materials as new materials to process non-woven environmental protection bags for customers. What I want to say here is the difference between new materials and ordinary materials. What is a new material? That is to say, in the process of raw material processing, non-woven fabrics without adding any recycled materials are called new materials. What is ordinary material? It is to add a certain amount of recycled materials proportionally in the process of processing raw materials, and the recycled materials mentioned here are also discarded non-woven fabrics, most of them are corners and corners cut off when making bags recycled by non-woven environmental protection bag manufacturers. Therefore, ordinary materials are generally cheaper than new materials. Secondly, in order to be able to identify whether it is a new material from the non-woven fabric, we can feel the type of fabric from the feel. Nowadays, the ordinary fabrics on the market are relatively hard, and the new materials are relatively soft. The difference between them is that the new material feels much softer, close to the real knitted fabric, and the toughness of the fabric is better than that of the ordinary material, and the tension is stronger and not easy to tear. But one thing, the same weight of the fabric, the new material feels thinner than the ordinary material, in fact, just an illusion. However, the feel of ordinary materials will feel harder and a bit like paper. The same weight of the fabric, the ordinary material is to be thick, because the non-woven fabric is also made of plastic particles, if the fabric is too hard, it will lose the flexibility and strong tension of the non-woven fabric. This method is also the usual method for many bad businesses to cut corners. Therefore, when we order non-woven environmental protection bags, we must first conduct a basic test on the fabrics used by non-woven environmental protection bag manufacturers, at least from the visual and feel, is it the fabric you want. If it is really impossible to tell, the general manufacturers have tensile testing equipment, as long as you know the conventional tensile data of non-woven fabrics, you can measure what kind of fabric the merchant uses.
