What are the factors that affect the bonding process in needle-punched non-woven cotton?

For needle-punched non-woven cotton, many factors affect fiber selection, web formation and bonding, including processing efficiency, product performance, application requirements, consumer requirements and use costs.

In the current selection of volatile materials, needle punched non-woven cotton fabric processors are looking for more flexible ways to use different fibers and polymers. In spunlace wipes, the raw material is usually composed of 50% absorbent fiber (viscose fiber) and 50% non-absorbent fiber (polyester or polypropylene), which fluctuates mainly according to the price of the raw material. Under current conditions, many wiping products reduce the percentage of viscose fibers, which can adversely affect absorbency and softness.






Softer needle-punched non-woven cotton products and sustainable solutions (environmental protection) are important trends in absorbent hygiene products. The global supply of viscose fiber is limited and there is no new capacity increase in the short term, which makes the price of viscose fiber rise. Cotton fiber will play a more important role in the needle punched non-woven cotton fabric, but it is also highly hydrophilic.

Needle-punched non-woven cotton cotton fiber has a long history in Asian countries, and its image is very positive, especially soft and environmentally friendly. However, the higher the cotton fiber content, the weaker the fabric because there are fewer bonding points. Thermal bonding, needle punching and spunlace needle punched non-woven fabrics cannot provide effective bonding to achieve the required fabric strength. While polymer bonding may be the most effective fiber bonding technology, it can more widely use cotton fibers as raw materials.
