Short note on different synthetic fibers

Short note on different synthetic fibers


Fiber Type : Nylon
Heat: Melts at 419F to430F.
Bleaches &Solvents: Will bleach. Degrades in mineral acids & oxidizing agents.
Acids & Alkalis: Insoluble in organic solvents Resists weak acids, inert to alkalis. Hydrolyzed by strong acids
Abrasion : Excellent
Mildew, Ag
ing &Sunlight: Excellent resistance to mildew and aging. Prolonged sun exposure can cause degradation.
