Name 5 properties of viscose
derivred from cellulose, similar properties to cotton, absorbant, weak, shrink and crease badly, silky feel

Describe some of the properties of synthetic fibres
strong, resist abrasion, lightweight, most are nonabsorbant, quick drying, don't crease or shrink, thermoplastic= soft when hot, not washed at high temps, melt and drip when set alight (molten fibre is very hot and can cause severe burns)
