Needle-punched non-woven fabric is a kind of non-woven fabric, which is made of polyester and polypropylene raw materials, and is made by multiple needle punching and proper hot rolling. Under the same processing conditions, why does the production of needle-punched non-woven fabrics have uneven softness and hardness? Let's take a look!
Under the same processing conditions, the reasons why the production of needle-punched non-woven fabrics will have uneven softness and hardness are as follows:
1. Low-melting fiber and conventional fiber are mixed unevenly. The part with higher low-melting point is harder, and the part with lower-melting point is softer.
2. The incomplete melting of the low-melting fiber causes the needle-punched non-woven fabric to be soft.
3. The high shrinkage rate of the fiber will also cause the problem of uneven softness and hardness of the needle punched non-woven fabric.
The above is the reason why the needle-punched non-woven fabric will have uneven softness and hardness under the same processing conditions. I hope it will help you.
