Molecular formula : MW : CAS :
nature : Poly names have acid fiber has diamine (-66 polyamide fibers). A polyamide fibers. Density 1.14. The temperature of about 253 ° C. Do not dissolve the general solvent, only soluble in such inter-methylphenol. The intensity filament 0.46 ~ 0.6 NIU / special (4.6 ~ 6.0 Caledon / day), elongation at 26% ~ 32%. Short fiber strength from 0.4 to 0.72 cow / special (4.0 ~ 7.2 Caledon / day), elongation of 16% to 42%. The system is widely used for knitwear, textiles, tire cord, fishing nets, ropes and other filter cloth. After processing can be made of stretch nylon, is more suited to the system, such as socks. General and adipic acid with 1,2-made nylon -66 salt, and then condensation obtained by melt spinning.
