TEXTILE FIBRES

  • The 3 main groups of fibres are:

     Natural (Wool)

     Regenerated (Viscose)

     Synthetic (Polyester)

  • They are fine hair-like structures that are in SHORT LENGTHS or as LONG CONTINOUS FILAMENTS
  • All fibres are made up of groups of molecules called POLYMERS
  • In the WORSTED process of wool means that it produces smooth yarns
  • In the WOOLEN process, short fibres are made therefore producing rough edges

Wool Technology

  • Cool Wool is a lighter weight wool fabric
  • Super wash is a shrink resistant process which enables products to be washed in washing machines without damage
  • Zirpro is a flame resistant finish for wool products used for protective clothing and aircraft upholstery
  • Virgin wool must be made from wool fibres which HAVE NOT previously been: spun into yarn, felted or incorporated into a finished product

Other Animals in Fibres

  • Alpaca and guanaco are types of llama which are bred for their FINE, SOFT, LIGHTLY CROPPED and WARM hair
  • They are used in expensive knitted jackets, overcoats and blankets
  • Cashmere comes from the coats of goats 
  • Cashmere items are VERY SOFT, LIGHT and LUSTROUS and is the most expensive hair fibre

Natural Fibres: Silk

  • Silk is made up from long-chain protein molecules which produce a continous filament
  • Made from a caterpillar of the silk moth
  • The fibres are continous filaments that are very strong
  • Examples made from silk are:

Chiffon

Satin

Damask

Taffeta

  • The most important silk-producing countries are China, India, Japan and Thailand
  • The silk seal shows that a product has been made from pure silk and guarntees a certain quality level

Natural Fibres: Cotton

  • Cotton is made from POLYMERS of cellulose which grows on small bushes
  • After the cotton bolls are picked, if wet, are dried using warm air then GINNING
