How is the density of needle punched cotton controlled?

With the continuous improvement of quality of life, the use of non-woven fabrics has also increased. Needle punched cotton is a type of non-woven fabric that is widely used, such as in car interiors, car air conditioning filters, medical absorbent dressings, pet water feeders, electronic cigarette oil absorbing materials, fruit and flower preservation, and so on!

The specifications and parameters used for needle punched cotton vary in different application scenarios. For example, many customers pay attention to its density, which affects the breathability, water absorption, filtration, softness, hardness, and feel of the needle punched cotton. In the production process, the density can be controlled by adjusting the speed of the needle punching frequency to produce various needle punched cotton with different densities and suitable for different purposes.
