How can I know how many grams of PP non-woven fabric? Thank you.

Gram weight can be simply obtained by cutting and weighing non-woven fabrics per unit area. The kind you are talking about is 80 grams of non-woven fabrics.

Due to different nonwoven processes, the thickness and feel of nonwoven fabrics with the same gram weight are also different. For example, 30 grams of hot air and 30 grams of hot-rolled non-woven fabrics are several times worse. Hot-rolled fabrics are thin and tough after rolling, and hot-air fabrics are loose as fluffy cotton. There are many non-woven fabric manufacturers in Shandong. You can check the bigger one online. Jinan Kang Jie Weifang Hailong Weifang Fujun Dongying Fujun's production equipment and technology are relatively advanced, and the scale is also relatively large.

A simple visual inspection of the quality of non-woven fabrics can look at the sun to see whether there are granular substances, whether there are cloud points, whether the vertical and horizontal tear difference is too large and so on.
