Flashcards in Fibres & fabrics- properties and characteristics Deck (32):
Give examples of natural fibres
cotton, wool, flax, silk
Give an example of regenerated fibres
Give examples of synthetic fibres
polyester, elastomeric, viscose, acrylic, nylon
Cotton properties and uses
Properties: cool to wear, soft handle, good drape, very absorbent
Uses: jeans, t-shirts, towels
Wool properties and uses
Properties: warm, absorbent, not durable, creases, can shrink
Uses: jumpers, suits and blankets
Flax properties and uses
Properties: warm, absorbent, durable
Uses: tea towels, tablecloths
Silk properties and uses
Properties: soft, warm, good drape and absorbent
Uses: evening wear, ties
What are combination fabrics?
They can be layered and combined to improve the handle, appearance, performance. Like lining and interfacing
Examples of combination fabrics
- Interfacing (to stiffen and strengthen collar or cuffs)
- Quilt (add warmth)
- Gore tex (breathable and waterproof)
- Kevlar (high strength used in bulletproof vests)
- Thinsulate (good insulator and moisture resistant)
What are examples of constructed fabrics?
woven fabrics, knitted fabrics, non-woven fabrics,
Types of weaves
What is a plain weave?
warp and weft are aligned forming criss cross pattern
Uses- strong and hardwearing furnishings
Yarn going horizontally of fabric
Yarn going vertically of fabric
Side where wefts are double backed so that there is no fraying
What is a twill weave?
diagonal pattern of warp and weft
Uses- strong and hardwearing things
- drapes well
What is a satin weave?
Longer float threads across warp or weft. It is a complex arrangement
Uses- light materials
high elasticity polymer
Why combine fibres?
Fibres are combined so that the material has many properties
What are examples of combined fibres?
Types of knitted fabrics
- weft knitted
- loops interlock vertically along length of fabric
- looping together long lengths of yarn across the fabric
how are non-woven fabrics made?
- webs of synthetic fibres bonded together
- animal hair/wool fibres matted together using heat, pressure and moisture
What are microfibres?
they are woven polyester fibres and can be used to construct woven, knitted, laminated and micro-encapsulated smart fabrics.
various microcapsules embedded in a fibre or fabric
uses: used to give a good smell and reduce body odour
examples of technological advances in textiles materials
- light sensitive (photochromic dyes)
- heat sensitive (therm-chronic)
-solvation chromism (changes colour when wet)
- Interactive fibres which incorporates electronics
- Fibre optics
What is a fabric specification?
a particular fabric/s used to make that specific product because certain properties are required
what are some popular fabrics?
