How to identify non-woven fabric environmental protection bag fabric?

First of all, we must know that the material of the non-woven environmental protection bag is naturally non-woven; it is also known as non-woven. However, we generally call it non-woven fabric. Nowadays, there are many kinds of non-woven fabrics in the market. There are brand new materials, common materials, laminating materials, etc. But if only from the eye’s vision to observe, the basic can only distinguish between coated and uncoated material. It is visually impossible to tell whether it is brand new or ordinary. However, in order to save costs, many businesses will treat ordinary materials as brand-new materials to process non-woven environmental bags for customers. What the editor wants to say here is the difference between new and ordinary materials. What is a new material? That is to say, in the process of processing raw materials, non-woven fabrics without adding any recycled materials are called brand new materials.

What is a common material? Is to add a certain amount of recycled materials in proportion in the process of raw material processing, and the recycled materials referred to here are also discarded non-woven fabrics, most of which are the edges and corners cut off during bag making when recycled by non-woven fabric environmental protection bag manufacturers. Therefore, ordinary materials are generally cheaper than brand-new materials. Secondly, in order to be able to distinguish whether it is brand-new materials from non-woven fabrics, we can feel the fabric category from the hand feeling. Nowadays, ordinary fabrics in the market are relatively hard, while brand-new fabrics are relatively softer. The difference between them is that the new material feels much softer, close to the real knitted fabric, and its fabric toughness is better than the ordinary material, with stronger pulling force and less tearing.

But one thing, the same weight of cloth, brand new material feels thinner than ordinary material, in fact, it is just an illusion. However, the hand feel of ordinary materials will be harder to touch, a bit like the texture of paper. However, for fabrics with the same gram weight, ordinary materials need to be thicker. Since non-woven fabrics are also made of plastic particles through processing, if the fabric is made too hard, it will lose the flexibility and strong tensile strength inherent in non-woven fabrics. And this kind of technique is also a common technique used by many unscrupulous businessmen to cut corners.
