The procces of creating fibrous material into yarn or thread. The act of finishing with a light-weight rod and a reel having a bail or similar device that gundcs the linc around a stationary spool which are often disengaged to let the road run fmcl). as “hen casting. Also called spin casting. spin fishing.
Classification of Spinning
Chemical Spinning Mechanical Spinning
Chemical Spinning:
Wet Chemical Spinning Wet spinning is that the oldest method of spinning a fibre. Again, the polymer is dissolved during a suitable solvent. Either the bathtub reacts chemically to coagulate (harden) the polymer, or it draws out the solvent from the polymer stream in order that the filament can harden. Viscose. polyvinyl and certain elastomerie Fibres are wet spun.
Melt Spinning: Nylon, polyester, saran and sulfar are produced within the manner.
Melt spun fibers are often extruded from the spinneret in several cross-sectional shapes (round, trilobal, pentagonal, octagonal, and others). Trilobal-shaped fibexs reflect more light and provides a beautiful sparkle to textiles
Dry spinning the method involves the extrusion of the acceptable liquid solution through the spinneret into an air chamber. The air reacts with the extruded streams causing them to solidify twisted and/or processed further then wound onto spools. This method of spinning is employed in manufacturing of acetate yarns.
Mechanical Spinning it’s the drawing out of an assembly of staple fibers to the specified thickness and inserting twist to impart the required strength to the yarn. during a mechanical spinning process the top product may be a single yarn
Ring spinning
Principal
To attenuate roving until the specified fineness is reached.
Drawing
Twisting
Winding
in the last step of yarn production, the staple fibers are fed to the ring spinning machine . after passing through the blow room (opening and cleaning) and therefore the carding frame.
It is the method of further drawing out roving to the ultimate yarn count needed, inserting twist to the fibres by means of a rotating spindle and winding the yarn on a bobbin. These three stages happen simultaneously and continuously.
A stationary ring is round the spindle, which holds the traveler. Yarn from the drafting unit is drawn under the traveler, then led to the yarn package. so as to wind the twisted yarn on a bobbin tube carried by the Spindle, the traveler is required to cooperate with the spindle. The traveler moves on the ring with none physical drive. but is carried along by the yarn it’s threaded with. The rotation rate oftraveler is less than the Spindle. and this difference within the speeds of traveler and therefore the spindle enables the winding of the yarn on the tube. A controlled up and down movement of the ring determines the form of the yarn package, called Cop or Bobbin. Ring spinning technology provides the widest home in terms of the yarn counts it can produce..
Rotor spinning or Open end spinning
The fibres are sucked down a delivery tube and deposited within the groove of the rotor as endless ring of fibre. The fibre layer is stripped off the rotor groove and therefore The twist within the yarn being determined by the ratio of the rotational speed of the rotor and therefore the linear speed of the yarn. sorts of textile machine during this post.
The fibres are then deposited into the rotor where wind and force deposits them along the groove of the rotor where they’re evenly distributed. The fibres are twisted together by the spinning action of the rotor, and therefore the yarn is continuously drawn from the centre of the rotor.
Rotor spun yarns are more even.somewhat weaker and have a harsher feel than ring spim yams. Rotor spun yarns are mainly produced within the medium count (30 Ne, 20 tex) to coarse count (l0 Ne, 60 tex) range.
the utilization of this technique has two basic advantages. it’s fed by sliver, not like the ringframe by roving. then eliminates the speedframe from the method line. It also can be modified to get rid of any remaining trash, thereby improving the yarn quality. Open-end spinning produces a special type ofyam to ringframe spinning. Open-end yarns tend to be more uniform. lower in strength, more extensible, bulkier. more abrasion resistant and more absorbent. lt is probably going then with all ofthese differences, just some Of wich are beneficial, that open-end spinning won’t replace ringspun yarn as originally thought. but are going to be a complimentary product.
Open-end spinning operates at a rate up to 5 times that of ring spinning and may be effectively used for cotton, polyester-cotton blends. also as other short and medium staple systems. Synthetic staple fibers like polyester alone can’t be effectively open end spun thanks to dusting of oligomer from the fibers that interferes with the spinning action of the rotor.
Short stable spinning
In short staple spinning three sorts of spinning systems are available during a wide selection . In ring spinning carded and com bed yarn are produced consistent with the need of yarn quality. , price as we“ as time consumption.
Spinning is the spinning of two or more strands of fibers. Mostly cotton fiber is a widely used fiber.These are yarn used for sewing, and are used for weaving or knitting.
2. What are benefits of spinning?
Spinning is an important process. If there is no spinning, no knitting can be made, no yarn can be made, all the clothes we wear are made by spinning.
3. What is spinning very short answer?
In short, spinning is the spinning of two strands.
4. What is spinning and weaving?
Spinning is the twisting of two strands. Weaving is the process of making spinning yarn into fabric.
5. How many types of spinning are there?
There are two important categories. They are wet Spinning Chemical Spinning.
