Introduction of Yarn Spinning
Yarn spinning is a process of making or converting fiber materials into yarns.[1] Since few centuries ago, spinning have been known as a process of converting raw materials(fiber) such as cotton and wool into yarns for making textile fabric or products. There are two classes of spinning process have been developed by people, Hand Spinning and Machine Spinning. In Textile Industry, the size of yarns is determined by unit of Tex, Count, Worsted, Woolen, and Denier
Hand Spinning
Before industrial revolution occurs, hand spinning method is widely used by people for making yarns. The principle is by using a tool such called carder or bare hand to align parallel the yarns before twisting
Carding
A tool such as wool card will be used to remove impurities on the surface and reduce clump to ensure the evenly spun during twisting process. Otherwise it may be done by bare hand.
Twisting
The end of wool fiber will be tied with the hook of the spindle, twist spindle in clockwise direction, if the twist too loose it may break the yarn during process.
Park
The yarn will be wrapped at the below section of the spindle
Machine Spinning
After industrial revolution, many developments have been done by the industry to ease the process by apply machine to control the process effectively. One of the oldest types of machine used by the industry since nowadays is Ring Spinning Machine
