textiles categories-
natural fibres
synthetic fibres
blended and mixed fibres
woven and non-woven fabrics
knitted textiles
fabric types-
wool-
felt
,
polycotton
cotton-
polyester
,
nylon
silk-
elastane
(
lycra
), acrylic
cotton-
a
soft white fibrous substance
which surrounds the
seeds
of the
cotton plant
and is made into
textile fibre
and
thread
for
sewing
cellulose fibres
are spun into
yarn
cotton is
soft
,
durable
and
easy
to
wash
,
creases easily
wool-
sourced from
animal fleece
easily spun
,
woven
or
knitted
naturally crease resistant and able to absorb to absorb dyes
absorb vapours and keeps a layer of dry air next to skin, thermal insulator
cotton-
plant fibres from
cellulose
look like
twisted ribbon
strong
,
absorbent
wool-
animal fibres
from
protein molecules
short scaly fibres
trap air
for
thermal insulation
synthetic fibres-
can be made from different types of
polymer
, derived from
petrochemicals
dyes
can be added to create
colours
polyester
,
acrylic
,
polyamide
(nylon)
strong
,
non-absorbent
,
washes well
,
easy blended ended
with other
fibres
polyester-
crease, stain resistant and strong when wet or dry
often
blended
with other
fibres
(eg
polycotton
)
seat belts
,
rain jackets
,
fleeces
acrylic-
lightweight, quick drying, crease resistant
mimics
natural fibres
like
cotton
and
wool
commonly used in
knitwear
and
sportswear
blended
fabrics-
two
or
more
fabrics blended for
enhanced properties
polycotton-
polyester + cotton
lightweight
,
soft
,
absorbent
bed sheets
,
pillow cases
,
clothing
elasticity-
how much a material will
stretch
and return to its
original
shape
resilience-
materials will spring back into shape after
deforming
or
compressive
force
woven textiles-
warns are
woven together
to
form fabric
plain weave textiles-
easy to produce and strong than more decorative weaves
stable
fabric construction
calico, muslin, gingham, taffeta
bedding
,
tablecloths
twill weave textiles-
distinctive diagonal lines in fabric
makes
thicker
fabric
curtains
and
soft
finishings
denim
non woven textiles-
sheet or web of
fibres
are
bonded thermally
,
chemically
,
mechanically
made directly from
fibres
, don't
fray
no
weaving knitting
is required
absorbency. sterility
, s, strength,
softness
,
flame resistant
,
cushioning
felted
fabric- dense, non woven fabric
matted
fibres
are pressed with
heat
,
moisture
felt is usually made of
fool
but can be mixed with
synthetics
to enhance resilience
not
elastic
,
deforms
when wet
knitting-
series or interlocking loops produces knitted fabric
Weft
knitting –the
interlocking loops
are formed horizontally, which enable it to stretch, but may lose shape
Warp
knitting –the loops
interlock vertically
, so the knit keeps it shape and is less likely to unravel or ladder
Weft
knits are suitable for
close fitting garments
as the stretch allows the wearer to move
comfortably
bonded fabrics
fibres are held together by
adhesives
fibres are
HEATED
if
synthetic
benefits of bonded fabrics-
resistant to
tear
and
breakage
fusion
between fabrics increases longevity and
strength
