Dry & Wet Spinning | Solution Spinning | Man made Fiber Production.
Gel spinning is sometimes described as dry-wet spinning, since the filaments first pass through air and then are cooled further in a liquid bath. Solvent spinning is used to obtain high strength or other special properties in the fibres. The polymer is in a "gel" state, which keeps the polymer chains somewhat bound together. 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 pass through a cooling. Recent developments in graphene oxide fibre (GO) processing include exciting demonstrations of hand woven textile structures. However, it is uncertain whether the fibres produced can meet the processing requirements of conventional textile manufacturing.

In wet spinning of chemical fibers from polymer solutions, jets of a polymer solution pass through a Figure 1 illustrates the pattern of wet spinning from a polymer solution. The pattern includes five (8) The process of fiber formation is considered for a single jet in the coagulating bath (interaction. Wet heat: The most popular method of sterilization both equipment and media is autoclaving at 121C with a pressure of 15 psi (pounds per square inch) for 15 min (1.02 kg/cm 2 ). Modern autoclaves are capable of providing saturated steam treatment ranging from 70-132 C, which is a pressure of up to 25 psi.
Vacuum Forming Process | Working.
Process in wet spinning, a non-volatile solvent is used to convert the raw material into a solution. the solvent is extruded through the spinneret either by simply washing it out or by a chemical reaction between the polymer solution and a reagent in the spinning bath. after extrusion, the solvent is removed in a liquid coagulation medium..

Fiber spinning processes Wet Spinning Dry Spinning Melt Spinning 5. Wet Spinning It is oldest process In wet spinning the polymer is dissolved in a non-volatile solvent. It is used for polymers that need to be dissolved in a solvent to be spun. 6. The spinneret is located in a coagulating bath that causes the fiber to precipitate out.

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.

Electrospinning and wet-spinning have been recognized as two of the most efficient and promising techniques for producing polymeric fibrous constructs for a wide range of applications, including optics, electronics, food industry and biomedical applications. The formation of "skin-core" structure in the viscose fiber is due to the heterogeneous precipitations taking place on the fiber cross-section during the wet spinning process: the viscose dope is extruded to the acid bath, and the a regenerated "skin" layer is formed first, then sulfuric acid gradually diffuses through the "skin" and solidifies.
