what are the advantages of synthetic fibre
Synthetic Fibres: Pros -Easy to wash -Most are resilient -Hydrophobic (hates water) -Nylon and polyester are thermoplastic -Cheap (e.g. Acrylic is a cheaper substitute of wool) -Strong & Hardwearing -Nylon is waterproof when closely woven Cons -High Static -Not Absorbent
Natural Fibres: Pros -Absorbent -Low Static -Wool and Silk are resilient -Wool and Silk are warm to wear -Cotton and Linen are cool to wear -Strong and Stronger when wet Cons -Cotton and Linen crease easily -Cotton: damaged by sunlight and mildew -Silk is very delicate and therefore is quite difficult to wash/dry etc, it scorches easily as well -Some people think wool is itchy -Some people think linen is uncomfortable to wear
If you have a blend of fibres they can cancel each other out.
Depending on what you need the fibre for will depend on which fibre you use.
I hope this helps :)
