(1) methyl silicone oil: namely polydimethylsiloxane, colorless, tasteless, transparent, viscous liquid, molecular weight of 5000-10000, soluble in ether, benzene, toluene, partially soluble in acetone, ethanol, butanol, insoluble in methanol, cyclohexanol, paraffin oil, vegetable oil. It can be us...
Melt blown method is mainly applied to polypropylene materials with high melt index. Island technology can only produce PET and PA66 fibers with diameters of 700nm or more. The production of nanofibers mainly depends on electrostatic spinning. However, electrospinning still has problems such as low ...
Preferred solvents include isopropanol, ethanol, and acetone. [0025] Amount of Water [0026] The amount of water to be added is important; it should be enough to solvate the surface of the fiber so that ionic groups on the surface macromolecules of the fiber can be freed to rotate to ...
