Actual factory and process configurations could vary, but our industry experts know them all. 

Opening / Cleaning Room

In the spinning mill, the bale opener is the first link in a long chain of processing steps in producing yarn. The bale opener releases fibre lumps out of the bales and transfers the fibres by airflow into the cleaning section.

Draw Frame

The draw frame stretches and parallelizes the textile fibres, a process that balances inequalities within the slivers. The card slivers pass through several stretching units between weight-loaded rollers and are spun down in loops into spin cans.

Combing

Combing is a process to prepare fibres for spinning and produces smoother, finer, stronger and more uniform yarns. Combing is commonly confined to high grade, long staple natural fibres. 

Ring Spinning

The spinning machines stake the roving, thin it and twist it, creating yarn. The roving is pulled off a bobbin and fed through rollers, which are feeding at several different speeds. This thins the roving at a consistent rate.

Open End Spinning

The rotor spinning process is much more efficient than Ring spinning and is mainly used for coarse yarns. 

Twisting TFO

Two or more single-end threads are twisted together to form one multi-ply twisted yarn. Spindles are driven by tangential belts or by separate motors.

Winding

Winders are machines for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape onto a bobbin. Modern machines are equipped with Elastic Belts for transporting the cop while older machines are driven by Tangential Belts.

Travel Cleaner

For cleaning Open end, Ring-spinning, Twister, Winder and Flyer machines pneumatically. Travel cleaners dramatically minimise manual cleaning work. Flat belts move the machine forward and backward and drive also the vacuum cleaner.

Texturing

Man-made fibres are in general very even and have less “character” when it comes to the sense of touch. Texturing is the formation of crimps, loops, coils or crinkles in filaments to give the yarn typical characteristics.
