materials Flashcards
Natural cellulosic
Cotton(seed), hem(bast), linin(bast), jute (bast)
- absorbent
-staple fibres (when cut for hemp) - conducts heat away from the body
- hemp/ jute: quick growing, doesn’t need pesticides or as much water as linen
Jute: used in areas of high humidity and agricultural packing (strong)
natural cellulosic
bamboo, soy, banana
- long (still staple) fibers
- strong
- lustrous
- absorbent
- similar to silk
soy: uv resistant, anti static, good for vegans, vegetable cashmere
natural protein: wool
staple fibers
warm
absorbant
how fluffy depends on spin
can depend on type:
alpaca, angora, chashmere
cellulostic protine: silk
long filliments up to a mile
absorbant
cool
moisture wicking
lusterous
manmade cellulosic
viscose
- from wood pulp with polymers
- filliment or staple
- silk wool or cotton
absorbant (for a manmade fiber) - soft against the skin
- can be made from cotton fibre blend
- regenerative
manmade cellulosic
acylate
- wood pulp
- very fine filliment
- used as microfibre,raincoats, machine thread
- often crimped
- shiney
- static
- low absorbancy
- fasty drying
- cheap alternative to silk
- lusterous
- good drape
man made cellulosic lyocell
- generic name for group of fibers from a plant
- important: tencel
- long continuos fibre
- most absorbant fabric
- similar manafacture to viscose
- more eco freindly( no polymers)
synthetic polyester
not absorbant
prone to static
filliment but can be textured
ofton strong and durable
light weight
hydrophobic
often crease resistant
thermoplastic fibres
can be strong
can be staple (if brushed)
synthetic nylon
- plastic chips melted down and extruded
thermoplastic
properties can depend on how its spun (flat, textured, staple)
good elasticity
bad absorbancy
can be breathable
synthetic elastain
filliments surrounded by coild of first and second covering
can stretch up to 7x
thickness and texture can vary
wont deteriorate from body oild
performance can be amended
made from petrochemicals
synthetic aramid
generic for fibres from petrochemicals
can be filliment staple or pulp
woven knitted or bonded
very strong
heat resistant
used for firefighting gear
inulating
kevlar and nomex
synthetic acrylic
from acrylonitrile
staple
can be spun into micro fibre
cheap
fast drying
prone to static
good elasticity
better at insulating than wool
shrinks if washed at high heat (thermoplasitc)
