test 10 Flashcards
what are examples of natural fibres
cotton, wool, silk
what are examples of regenerated fibres? (chemically modified)
viscose rayon, acetate
what is a fibre blend?
when fibres are blended based on their characteristics to create a specific end use
example of fibre blend
polycotton
what are the three fabric structures
woven, non woven and knit
what are the 3 woven fabric structures
plain - light, easy to use, no right or wrong side. examples poplin, organza, flannel, cotton
twill - interlacing of warp and weft on the left to create diagonal, stronger, weft passes two or more warp yarns. examples denim, drill
satin - creates long floats over weft yarns, warp yarns floats over four warp yarns
what are the three types of yarns
monofilament, multifilament, staple spun
what is staple spun yarn
- made from staple fibres such as cotton or wool or synthetic fibres cut short
- uneven, weak, poor lustre
- used for apparel and furnishings
what is monofilament
- made from one filament of a manufactured fibre eg rayon, polyester, nylon
- fine, strong lustre, good durability
- used for fishing line, stockings, invisible thread
what is a multifilament
- made from two or more filaments of a manufactured fibre eg. rayon, polyester, nylon
- good lustre, absorbency
- evening wear, costume
what are the types of cotton yarn spinning
low twist yarns and high twist yarns
AND
carded and combed yarns
what is carded and combed yarns
carded - medium to low twist, uneven thickness, poor resilience, soft, stong, comfortable
combed - medium to high twist, fine appearance, moderate drape, harder handle, less resilient, refined
aesthetic criteria include
drape (how it hangs), lustre (how it shines), handle (how it feels)
functional criteria include
absorbancy
durability
thermal properties
resilience (no creasing)
abrasion restistence (resistance to rough surfaces)
elasticity
dimensional stability
strength
properties of cotton
poor lustre, poor drape (depends of fabric construction), cool and crisp poor resilience, moderate abrasion resistance, good strength (becomes stronger when wet), highly absorbent, dimensional stability(remains in shape due to inelasticity), poor elasticity, cotton burns quickly
properties of wool
poor lustre, good drape, handle varies, moderate abrasion resistance (due to scaly surface), weak, good absorbency, good resilience, good elasticity, poor dimensional stability, self extinguishes
properties of polyester
lustre depends on fibres of cross section and chemicals, drape depends on yarn and fabric construction, handle depends on shape, good abrasion resistance, good strength, poor absorbency, excellent resilience, strong dimensional stability, moderate elasticity, burns slowly
properties of polycotton
lustre depends on percentage blended fibres, drape depends on percentages blended fibres, handle depends on percentage blended fibres, better abrasion resistance compared to all cotton, good strength compared to all cotton, good absorbency, good resilience, good dimensional stability, good elasticity, flammability depends on percentage blended fibres
sectors of the textiles industry
textiles production, allied industries, footwear, clothing
factors affecting consumer demand
social trends, marketing strategies, gender, age, ethical and environmental considerations, cost
social trends
greater awareness of the effect of textile production and manufacture, sustainable products, protection eg sun, fashion trends
4ps of marketing
product, place, price, promotion
7 elements of design
colour
shape
line
size
direction
value
texture
8 principles of design
contrast
rhythm
dominance
balance
unity
emphasis
proportion
repetition
