.
what are thermoplastic fibres?

What does mercerization consist of?
permanent finish
consists of treating the material under tension with cold sodium hydroxide solution.
this is considered one of the most important finishes for cotton, it gives luster, hand and drape. Also increases the strength and improves dye affinity.
what are the subcategories of shrinkage control?
relaxation shrinkage- occurs when fibres and yarns are under tension
progressive shrinkage- occurs each time a fabric is is laundered
residual shrinkage- small amount of shrinkage that occurs after its been preshrunk
what is glaze chintz

what is an antimicrobial/bacterial finish and what does it do?
has chemical agents that inhibit growth of bacteria and fungi
(important for items that have contact with skin ie. underwear
define napping
a mechanical finish of woven/knitted fabrics where it is passed against rotating wire covered brushes.
The outcome provides better insulation and a softer hand.
- subject to pilling
define bleaching
a finish that is a result of exposure to sunlight or a chemical process
what is a UV finish and what does it do?
this finish offers protection to one’s skin where chemicals absorb UV rays and coat the fabric surface
what are water repellents
a chemical finish that uses waxes and emulsions that resists the penetration of fabric, but permits the passage of moisture.
what is used as stain repellent
fluorocarbons
