Physical Treatment
Dissipation of electrical charges accumulated on the surface of synthetic or animal fibers prevents processing difficulties in textile mills. This action, known as static charge dispersion, is achieved by increasing the moisture content or applying specialized antistatic chemical finishes. It is critical for high-speed fiber processing.
Processing Benefits
Fibers with high static charges repel each other and stick to the metal parts of processing machinery. This behavior causes issues like fiber fly, uneven drafting, and frequent breakages during the carding and spinning stages. Dispersing the static charge ensures that fibers remain aligned and flow smoothly through the machinery.
Chemical Additives
Antistatic agents work by increasing the electrical conductivity of the fiber surface. These chemical compounds absorb moisture from the surrounding air, which allows the static charge to flow away harmlessly to the ground.
Fiber Handling
In cashmere processing, where fibers are extremely fine and delicate, managing static electricity is essential to prevent fiber damage. Mills maintain high relative humidity in their spinning rooms to naturally aid in dispersion. This environmental control, combined with appropriate chemical treatments, protects the fiber quality and ensures consistent yarn production.
By minimizing static build-up, the mill can operate spinning frames at their maximum rated speed without risking excessive yarn hairiness or tension spikes that lead to downtime.
