What is the reason for the uneven weight of the finished non-woven needle punching machine?

Acupuncture non-woven fabrics are made by combing the non-woven raw materials through a carding machine, and then overlapping and needling multiple layers of raw materials. During the carding process of the non-woven needle punching machine, sometimes due to uneven carding, the final product gram weight will be slightly different, but generally not too much. The final product quality has a great relationship with the quality of the equipment and the technical level of the technicians.

Why are thermal bonding fibers mixed into the production process of the non-woven needle punching machine?

In the production process of non-woven needle punching machine, heat-bonding fibers are mixed into, and hot-rolled after needle punching can improve the strength and dimensional stability of needle-punched non-woven materials, but the hardness of non-woven materials increases, and the resistance to multiple bending decline.

This method cannot usually be used as a reinforcement for needle-punched nonwovens alone, but can only be used for additional reinforcement of the needle-punched nonwovens on which the base fabric is laid. No thermal bonding fibers are mixed in the fiber web. After needle punching, it can be ironed and bonded with fiber hairiness after hot rolling treatment, improving the surface quality of needle punched non-woven materials. When used as a coating base fabric, the coating amount can be reduced.

How to improve the longitudinal elongation of needle punched non-woven fabrics

Mainly from the following five aspects to make adjustments to improve the longitudinal elongation of needle punched non-woven fabrics

1. Replace fibers with large elongation;

2. Adjust the cylinder and doffer of the carding machine of the non-woven needle punching machine to reduce the accumulation of longitudinal fibers;

3. Reduce the amount of draft during the needle punching process of the non-woven needle punching machine;

4. Reduce the needle punching density of the non-woven needle punching machine;

5. Reduce the ironing temperature of the non-woven needle punching machine;
