How to identify the quality of non-woven bags

How to identify the nonwoven fabric eco-friendly bag fabric? First of all, we need to know that the material of non-woven eco-friendly bags is naturally non-woven, also called non-woven. But we generally call it non-woven fabric. There are many kinds of non-woven fabrics in the non-woven market today. There are brand new materials, ordinary materials, coated materials, etc. And if it is only observed from the eyes of the eyes, basically it can only distinguish between coated and uncoated materials.

Visually, it is impossible to distinguish whether it is brand new or ordinary. In order to save costs, many businesses will treat ordinary materials as new materials for customers to process environmentally friendly non-woven bags. Secondly, in order to be able to distinguish whether it is brand new from the non-woven fabric, we can feel the type of fabric from the feel. Nowadays, ordinary fabrics on the market are relatively hard, while new materials are relatively soft.

The difference between them is that the new material has a much softer feel, close to the real knitted fabric, and the toughness of the fabric is better than that of ordinary materials. The tensile force is stronger and it is not easy to tear. But there is one thing. The new material of the same weight of fabric feels thinner than the ordinary material. In fact, it is just an illusion. The texture of ordinary materials will feel harder to the touch, a bit like the texture of paper. For the fabric of the same weight, the ordinary material is thicker.

Since the non-woven fabric is also made of plastic pellets after processing, if the fabric is too hard, it will lose the inherent flexibility and strong tensile force of the non-woven fabric. Sex. And this method is also a common method used by many unscrupulous businesses to cut corners. Therefore, when we order non-woven eco-friendly bags, we must first perform a basic test on the fabric used by the non-woven eco-friendly bag manufacturer, at least to identify whether it is the fabric we want from the visual and feel.
