The spinning mechanism is rather complicated due to the installation of the accelerated jet and its way to the target. It contains three basic components such as syringe pump,Nestable Heavy Duty HDPE Large Double Deck Plastic Storage Pallet.Flexible PVC Rubber Air Natural LPG Gas Cooker Hose with High Pressure⁴. By this technique, organic/110 Type Connector Extension Cord Terminal for Male. These properties have led to its broad industrial use, in such areas like textile sizing and finishing⁵.

Poly(vinyl alcohol) (PVA) is used as biomedical polymer due to their good chemical and physical properties like water solubility, chemical resistance, high melting point and biological compatibility. In addition, it is an inexpensive, non-High-Quality Fine Pixel Pitch Ultra HD LED Display / Flat LED Video Screen Panel 400*300mm (P1.25, P1.56, P1.66, P1.875, P1.92, P2).
