Under the same processing conditions, the reasons for the unevenness of the production of needle-punched nonwoven fabrics(PP Needle Punch Non Woven Fabric Manufacturer) are as follows:

1. The low-melting fiber and the conventional fiber are unevenly mixed, the part with a higher low melting point content is harder, and the lower part is softer.

2. Incomplete melting of the low melting point fiber causes the needled nonwoven fabric(Diy Felt Fabric Vendor) to be soft.

3. The high shrinkage rate of the fiber also causes the problem of soft and hard unevenness of the needle-punched nonwoven fabric.

The above is the reason why the production of needle-punched non-woven fabrics will be uneven under the same processing conditions, I hope to help you.
