11 Cards in this Set
- Front
- Back
Cotton
|
- cellulose
- from the cotton plant - kidney or bean shape structure - burns rapidly - high wet strength - high absorption - dries slowly - poor elasticity therefore creases easily - lower insulator - good durability |
|
Flax
|
- cellulose
- from the flax plant - irregular polygon structure - burns rapidly - poor insulator - highly absorbent - very low elasticity - creases easily - good durability |
|
Wool
|
- protein
- from sheep - round structure with scales - burns slowly - large amount of trapped air due to the scales therefore a good insulator - water is absorbed slowly due to the hydrophobic nature of the fibres - dries slowly - not very durable - not creased easily |
|
Silk
(degummed) |
- protein
- from silk worms - rounded triangle structure - burns slowly - cooling effect on the skin - can provide good insulation as there is a layer of air trapped between the fabric and the skin - good resilience - does not crease easily |
|
Viscose and Modal
|
- regenerated cellulose
- extracted from wood - structure depends on spinning conditions - burns rapidly - low wet strength - very absorbent - modal has a higher wet strength than viscose - easily wrinkle - easily dyed |
|
Lyocell
|
- cellulose
- derived from wood - structure made of fibrils - good wet and dry strength - low elasticity |
|
Acetate and Cupro
|
- cellulose
- structure depends on spinning conditions - acetate melts when burned - cupro burns rapidly - cupro is good at absorbing - acetate has a low absorbency |
|
Nylon
|
- polyamide
- made by polymerisation - structure depends on spinneret - shrinks and melts when burned - insulation properties depend on whether the fibre is produced as flat filament, textured filament or staple yarn. - low absorption - very strong - wrinkle-resistant |
|
Polyester
|
- poly (ethyleneterephthalate)
- made by condensation polymerisation - structure depends on spinneret - shrinks and melts when burned - hardly absorbs water - flame resistant - highly durable |
|
Acrylic
|
- polyacrylonitrile
- made by polymerisation - structure depends on spinning conditions - shrinks and melts when burned - wrinkle resistant - good insulation - similar to wool in character |
|
Elastane
|
- polyeurethane
- fibrillar - shrinks and melts when burned - high elastic recovery - made only as filament yarns - wrinkle-resistant |
