Spinning is the process of conversion of textile fibers and filaments into yarns for weaving or knitting into fabrics. In this article, we are going to know about the various processes which lead to the formation of worsted spun yarns. Worsted spun yarns differ from the regular woollen yarn in various properties. NEW SPINNING SYSTEMS BY D.GOPALAKRISHNAN INTRODUCTION Spinning is the process of producing yarn. This can be divided into two groups i.e., Spinning Ring spinning Open-end spinning •Rotor Spinning •Airjet Spinning •Self twist spinning •Friction Spinning etc., Electro static spinning Delivery speed Upto 40 m/min Raw material cotton Count range Ne 20-40 Form of feed stock Roving. Cotton is a plant-derived natural seed fiber extensively used in the textile industry to manufacture yarns. The cotton linters are regarded as a valuable by-product of cotton processing and are used as an alternative source of cellulosic raw material in the pulp and paper industries (Sczostak, 2009).During the processing of cotton in spinning industries, around 8% wastes are generated in the.

An Overview of Jute Spinning Process. Mustaque Ahammed Mamun. Department of Textile Engineering. Dhaka University of Engineering & Technology (DUET) Email: Introduction: Jute is known as the "golden fiber" due to its golden brown color and its importance. Jute belongs to bast fiber category and is normally spun in the. Weaving. Prepared beams are set on a looming frame to weave a textile in the following five motions: 1. Shedding: two groups of warps are opened to let the weft pass through. 2. Picking: The weft is inserted between two groups of warps. 3. Beat-up: Pushing the newly inserted yarn back into the fell using reed. 4. 1.1 Short-staple yarn spinning. Spinning is defined by Barker as the " art of throwing a number of more or less short fibres together in such a way that, being drawn out to form a comparatively fine filament " [].In this process, one of the main defining parameter is fiber length. According to fiber length, machinery and their adjustments that should be used are determined.

Any mechanical handling, up to and in- cluding spinning, may modify the natural quali-. In the case of open-end spinning, the twisting force is generated by the rotation of a rotor and is transmitted by friction to the fibers that make up the tail of the newly-formed yarn. As this twisting tail comes into contact with other fibers, it collects them.

MELT SPINNING In this process, a polymer is melted and heated to a suitable viscosity for fiber production. The melted polymer is pushed through a spinneret, which is a type of die consisting of several small holes. Each hole produces an individual fiber, and the number of holes on a spinneret defines the number of fibers in the yarn. The melted polymer fibers then passes.

Cotton Ginning Process At first, the cotton will go through dryers to reduce moisture content. Then the cotton is to go through cleaning equipment to remove foreign particles or materials. The cotton is then sent to the air conveyed to gin stands where revolving circular saws pull the lint from the saw teeth by air blasts or by rotating brushes.
