Weaving and Spinning is related each other. One is impossible except other. Before going to process of weave, we must have to have in our hand some yarn, which I can get from the process of Spinning. So it can be said that "weaving+spinning" is most crucial fact on textile processing. Firstly I will discuss about something of spinning.
The last step of spinning is Ring Spinning. Ring Spinning is a universal system. The process involved in ring spinning is creeling, drafting, twisting, winding, building up and doffing. In normal ring frames, the number of spindles are 400-500, but 1000 delivery i.e. spindle per ring frame is also available. The delivered roving in bobbin from is fed in the creels of the ring frame. The roving are unwound by pulling action and passed through the drafting zone. At the front side of drafting rollers that is front roller, the drafted fibres become twisted and forms yarns. The twist is inserted by the ring and traveler. The traveler rotates by yarn tension and spindle speed. One turn of traveler inserts one twist on the yarn. Delivery package that is yarn bobbin is situated on the spindle. The delivered yarn is wound on the yarn bobbin. Up and down movement of the ring rails f facilitates yarn winding through out the height uniformly on the yarn bobbin.
The spindle speed of the ring frame govern yarn production rate. Normally spindle speed varies from 10000- 20000 r.p.m. the simple production calculation of a ring frame is as follows:
Production per spindle per minute= spindle RPM / yarn TPI
=Yarn delivery in inches per minute.

Now I will tell you something about weaving:

Woven fabrics are produced in the weaving machine. In woven fabrics two series of yarns are observed. The yarns laid in length dire4ction of fabric are called warp yarn and the yarn laid in width direction of fabric is called weft yarn. The warp yarns are also called ends and the weft yarns are also called picks .the warp and weft yarns are bound together by their interlacement called fabric structure. The most common fabric structures are plain and twill for woven fabrics.
