Class 8ScienceSynthetic Fibres and Plastics
Synthetic Fibres
Made from chemical processes (petrochemicals). Unlike natural fibres (cotton, silk, wool). Types: NYLON โ first synthetic fibre (1935), strong, elastic, durable, used in parachutes, ropes, brushes, stockings. POLYESTER โ resists wrinkles, dries quickly, blend with cotton (polycot). ACRYLIC โ looks like wool, cheaper, used in blankets/sweaters. RAYON โ from wood pulp, silk-like, blend natural+synthetic.
