Winding and Clearing up

Refolding and Rewinding 

Step-by-Step manufacturing process is following below:

Step 1: Sheep shearing:  A process where the woolen sheep fleece gets cut off and recognized as fleece. The fleece is also the grease wool containing oil and lanolin.

Step 2: Sorting process: Sheep-sheared wool gets sorted in different qualities and textures. Then, it gets sorted into different grades based on the parameters.

Step 3: Scouring: After taking the wool from the sheep, it gets renowned as raw or grease wool. It contains dirt and grease. To remove this dirt, the wool goes through a scoured series of alkaline baths. This bath contains water, soda, and soap. The rollers squeeze excess water from undried fleece.

Step 4: Worsted Carding: In the carding process, carding untangles and individualizes fibers. The vegetable matters remain in the wool even after scouring and drying. In carding, the foreign matters’ bulks get removed. This process also achieves a mixture of wool fibers.

Step 5: Preparative Gilling: The gilling machine is a gill box in real. This process aligns the fibers in a direction. In which, it blends the wool through the process of doubling. It also adds moisture and lubricants by using a coarser comb. The main aim of this process is to align the fibers in a card silver and to blend the silvers from the different cards.

Step 6: Combing: Combing, a critical step, goes through the worsted processing. It removes short fibers, impurities, and neps. It forms a continuous rope-like silver.

Step 7: Finisher Gilling: The aim is to remove the entanglement. Entanglement that gets introduced to the silver, named combed.

Step 8: Drawing: It is a supreme operation. In this operation, the drawing doubles and redoubles the silvers from the wood fibers. This process winds the stock, draws, drafts, and even twists too. Making the silvers more compact, this process of thinning into sobbers.

Step 9: Roving: Silvers, gained from the draw frame, get subjected to a frame named roving. This is to produce rovings. Here, the roving frame draws out silvers. For spinning, a slight twist gets inserted to form lengths in a suitable range. Roving applies to get spun into the yarn on a frame, named spinning.

Step 10: Spinning: Roving gets spun into yarn through more yarn twisting.
