The process of converting fiber into yarn is called as Spinning. Flow Chart of Spinning: Pic- Carded Yarn flow chart Pic- Combed Yarn flow chart Objectives: Blowroom: Opening: Open the material into very fine tufts Cleaning: Eliminate most of the impurities. Mixing and Blending: Provide a good blend of two different fibers. When polymer granules or chips form the starting material for melt-spinning, they are first dried and then melted in the extruder. The homogenized and filtered melt is squirted through narrow channels into a quench chamber where solidification of the fluid filament bundles is achieved Fig. 4.1. On the contrary, ring spinning is deemed to be the most widely used spinning system because of its versatility in producing low-twisted soft, absorbent yarn for knitting to.

Automated systems have been developed for all manual operations in several stages: 1. Automatic gripping and introduction of the sliver end from a new can into the spinning box. 2. Automatic cleaning of rotor, draw-off nozzle and draw-off tube after ends down, quality stops or package changes; 3. Motion and force Ref 14. Metal spinning typically involves the forming of axisymmetric components over a rotating mandrel using rigid tools or rollers. There are three types of metal-spinning techniques that are practiced: manual conventional spinning Ref 1, 2, power spin-ning Ref 411, and tube spinning Ref 7, 8.

COMPUTER MODELLING OF THE LYOCELL FIBRE SPINNING PROCESS.
Spinning is the act of taking animal fibers or vegetable fibres and twisting them to form a continuous, infinitely stretching yarn suitable for weaving. Simply put, it is the process of spinning fibres into yarn by mechanical. Spinning is a sheet metal forming process in which a metal blank is pressed over a rotating chuck or form mandrel with the help pressing tool to obtain axisymmetric hollow shell. The sheet metal parts that have circular cross-section can be made by this process.

Spinning Basics Page 2 of 7 Main Program Now, the main part of the program begins. The instructor arranges elements, such as those shown under the Spinning Elements section into a 45 to 60 minute program. Since each instructor does it differently, spinning programs vary considerably. However,. In most cases, forward tube spinning process is usually adopted to manufacture thin-walled tubular components with a high length- diameter ratio [7]. In this spinning process, however, flaring may occur at the opening end of workpiece Fig. 2 [810]. This can easily lead to fracture at the tube end in the subsequent spinning process. An improved process for spinning aramids from solution using the air gap wet spinning method involves using a coagulant that contains 1 to 1000 ppm by weight of an organic polymer that acts as a drag reducer. Improved productivity and/or finer aramid fibers is obtained with no deterioration of fiber physical properties.

Spinning is the process of taking textile fibers and filaments and making them into yarn. For thousands of years, people spun natural fibers into yarn by hand. Today, spinning involves many. Melt spinning is the most economical process of spinning due to the fact that no solvent is recovered or evaporated just like in solution spinning, and the spinning rate is fairly high. Melt spinning is the preferred method of fabricating polymeric fibers and is used extensively in the textile industry. Fig. 1.5 shows a schematic of the melt-spinning process. There are 3 main process parameter are consider for spinning process. These process parameter are as follow 1. Workpiece Parameters a. Blank thickness b. Blank Diameter c..

Processing of polymers to produce high-modulus and high-strength fibers has two generic routes: 1 spinning of stiff, nematogenic polymers to form oriented structures in solid state, and 2 morphological manipulation of flexible polymers into highly oriented extended-chain fibers through complex processing. Reaction spinning Spandex Rayon viscose process 6.9.2.1 Melt Spinning - Melt spinning uses heat to melt the polymer to a viscosity suitable for extrusion. This type of spinning is used for polymers that are not decomposed or degraded by the temperatures necessary for extrusion. Polymer chips may be melted by a number of methods. In the present chapter, the solution-spinning processes will be briefly described. Keywords Coagulation Bath Coagulation Rate Cellulose Triacetate Hydraulic Drag Bicomponent Fibre These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
