Spinneret stretching in the wet forming zone 1. Characters of the stretched state of the spinning line in the forming zone (1) Spinneret stretch rate: a(%)= (VL-VO)/VO*100(2) Spinneret stretch ratio: ia= VL/VO= a/100+1(3) Average Axial Velocity Gradient: (x)a= (VL-VO)/Xe In the above formula

AT226 Series Plunger-type Melt Spinning Machine is used to carry out the melt spinning of polypropylene, polyester, polyamide and other special materials with plunger metering system. The raw material melts and flows into the plunger-type cylinder. The plunger-type cylinder driven by the servo motor

1. SummaryAT235 Bench-top Wet Spinning Machine is special design for researching new material in the field of textile, macromolecule and other material. It consists of the solution tank, dosing pump, spinneret, coagulating bath, drawing roller, heating channel, drawing roller, setting channel, drawi

Dissolution rate is also very important for production This sweling rate has an important effect on the dissolution rate of the polyment The sweling degree polymer increases with time ,and also depend on the properties and composition of solvent,temperature ,pressure and other conditions

1.Phase equilibrium of polymer solvent system In the preparation of spinning stock solution, it is necessary to choose the appropriate polymer solvent system, in order to prepare uniform single solution under general technological conditions;  In the preparation of spinning stock solution, it is necessary to choose the appropriate polymer solvent system, in order to prepare uniform single solution under general technological conditions;  

Effects of supramolecular deconstruction1. Amorphous polymers are more solube than partly crystaline polymers. This is because the force between the former macromolecule is weak,and the latter due to the strong force between the molecules of the crystalline part,to make it completely dissolved,a hi

Affects solubility about stucture(一）Infuence of macromolecular chain structure1. The stronger the intermolecular force,the less likely the polymer is to dissolve.The intermolecular force is t,If the solution can weaken the forces between the macromolecules,it will increase the solubility of the

Generally, man-made fibres are produced by spinning the polymer. In this article, we will introduce melt spinning and wet spinning in the three major textile processes.
