Fibres and fabrics - OCRSurface treatments and finishes

Textiles are made from fibres, classified as either natural or manufactured. Fibres are twisted into yarns before being made into woven, knitted or bonded fabrics.

Surface treatments and finishes

are applied to fibres and fabrics to either enhance the appearance of the material or to protect it from general wear to ensure it lasts longer.

Surface treatments can add decoration, protection and function to a textile:

  • printing - inkjet printing onto specially treated paper can be heat pressed onto fabric to provide a permanent image
  • flame retardant - chemical additives can be sprayed onto fabric to slow down its burn time
  • water repellent - silicone-based chemicals can be sprayed onto provide a protective barrier
  • crease resistant - a resin can be applied to stop creases setting
  • stain resistant - a silicone-based spray can stop stains being absorbed into the fabric
  • - calendering sends fabric through heated rollers and makes it smooth
  • brushing - fabric is sent through a series of fine wire-toothed rollers, which gives it a soft, fluffy surface
  • embossing - synthetic fibres are sent through heated, decorative rollers pressing the pattern texture into the fabric
  • - adding a cellulose enzyme to the washing process causes a stonewashed, mainly used on denim
  • - especially used on cotton, sodium hydroxide is added to the fibres making them swell to give a shiny appearance
