Environmental protection bag manufacturers teach you to identify non-woven environmental protection bag
There are many kinds of non-woven fabrics in today’s non-woven market. At present, non-woven fabrics on the market have new materials, ordinary materials, coated materials, etc.
And if only from the visual effects of both eyes to observe, the basis is only to distinguish between coated and non coated materials.
Ordinary people only observe from the visual effects of both eyes, and the basis is to distinguish between coated and non coated materials. It is impossible to separate whether it is brand-new material or ordinary material in visual effect.
In order to better reduce costs, some of factory may will use ordinary materials as new materials to produce and process environmental protection non-woven bags.
What the manufacturers of environmental protection bags say here is the difference between brand-new materials and ordinary materials.
What is a new non-woven fabric? In other words, in the whole process of raw material production and processing, non-woven fabrics without add recycled materials are called brand-new materials.
Ordinary materials are generally cheaper than new materials.
In order to better identify whether the non-woven fabric is brand-new or not, we can feel the fabric type from the touch. Nowadays, ordinary fabrics in the sales market are relatively hard, while brand-new materials are relatively soft.
The touch of ordinary materials will feel hard, much like the layering of paper. For fabrics of the same weight, ordinary materials should be thick, because non-woven fabrics are also made of plastic particles after production and processing. If the fabrics are made too hard, they will lose the flexibility and strong tensile force of non-woven fabrics.
However, for non-woven fabrics of the same weight, brand-new materials feel that they need to be thinner than ordinary materials. In fact, it is just an illusion.
