What are the important factors that affect the non-woven bulla force?

Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally finishing The resulting non-woven fabric. A new type of fiber product with soft, breathable and flat structure, and has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials. It is widely used in application fields such as luggage, home textiles, medical sanitary materials, bedding, sofas, and automobiles.
Because the raw material of the non-woven fabric is polypropylene, the hand feel of the non-woven fabric is related to the temperature of the processing material. When the temperature is high, the hand-feel of the non-woven fabric is relatively hard, and the hand-feel of the non-woven fabric is relatively soft when the temperature is low. .
If the non-woven fabric is too hard, it will be more brittle, the tension will be very bad, and it will be very simple to crack. On the contrary, the non-woven fabric with soft hand feels very good tensile force and full of toughness.


Most manufacturers like to make hard materials, and many poor non-woven fabric manufacturers use this to cut corners, because the fabric of the same weight will feel much thicker than the material after the fabric is hard.
Hard material is the most common method used by non-woven fabric manufacturers, because the fabric will feel thinner after it is soft. The soft material feels very soft and close to the actual knitted fabric, and the fabric has good toughness and strong tensile strength and is not easy to tear. .
Youyu non-woven fabric manufacturer knows that, and hope to help you!
