The production process of non-woven fabrics is very complicated and needs to be made through a series of processes such as spunbond, spunlace, heat sealing, needle punching, meltblown, and hydrophilic. Of course, there are some differences in the fabrics of each process. Most of the non-woven fabrics that we usually contact have many characteristics, such as moisture resistance and easy decomposition, non-toxic and non-irritating, etc. Therefore, environmentally-friendly non-woven bags have also been greatly developed in China in these years.

The quality of non-woven fabrics is mainly affected by the particles of raw materials. The non-woven fabrics produced on the market are different from new materials. The ton price of new materials is several thousand higher than that of recycled materials. The price on the bag will be much different, we check the quality of the non-woven fabric by checking the corresponding parameters.

At present, we mainly detect through the following aspects:

1. Stretchability and abrasion resistance of cloth.

2. Color fastness of the cloth after rubbing, color fastness after washing.

3. Antistatic and burning properties of cloth.

4. Moisture regain, air permeability, moisture permeability, oil content, and fabric purity
