1. Acrylic acrylic fiber raw material for the production of cheap acrylic by-productof oil due to acrylic polymer when heated to more than 230C only decomposes without melting, so it can't melt spinning like polyester, nylon fibers, and by solution spinning method. Spinning can be dry, wet can also be used. Dry spinning speed ishigh, suitable for spun silk. Wet spinning process for short fiber, fluffy, used for wool-like fabric.
2. The performance and application of elastic acrylic: it's flexible, second only to the pet, about twice higher than nylon. Good shape retention. Strength: strength than acrylic polyester and nylon, but 1~2.5 times higher than wool. Heat resistance: fiber softening temperature is 190~230C, after in the synthetic fiber polyester. Lightfastness: acrylic light resistance is the best of all the synthetic outdoor exposure forone year, intensity fell by only 20%.
