Needle-Punched Carpet

Needle-punched carpets are used in exhibitions, exhibition halls, celebrations, opening ceremonies, weddings, and similar events. There are two common processing methods for needle-punched carpets. One is performed on a needle punching machine equipped with multiple lamella strips as the bed plate using fork needles. The other is carried out on a random velour needle punching machine equipped with a moving brush plate as the bed plate using special crown needles or fork needles.

When using the aforementioned pre-needling needles, the optimal needling density is 80 punches per square centimeter for velour fabrics and 120 punches per square centimeter for ribbed fabrics. After the pre-needling is completed, the material is fed into a structuring needle punching machine, where fork needles and crown needles are used to complete each subsequent process.
