Material categories and properties - EdexcelTextiles

All materials have physical and working properties. Physical properties are the traits a material has before it is used, whereas working properties are how the material behaves when it is manipulated.

Textiles

Types of textiles and their uses

Textile materials can be found naturally or can be formed synthetically. They can be processed into different forms such as , or .

Natural fibres

Natural fibres come from plants or animals. They are easily and .

Natural fibrePhysical propertiesWorking properties
CottonGrows on a cotton plant in a ball called a boll, fibres are combed and spun into a yarnTakes dye well, soft, strong, absorbent, recyclable, used in clothing
WoolSpun from animal fleece such as sheep and alpacasCan be fine or thick, soft or coarse, takes dye well, warm and crease-resistant, used in clothing and carpets

Synthetic fibres

Synthetic fibres are made mainly from coal and oil into and do not easily.

Synthetic fibrePhysical propertiesWorking properties
PolyesterCan be woven or knitted, thick or thin and available in a variety of colours, can be blended with other fibres for better properties (see polycotton)Strong and versatile, it holds colour and washes well
AcrylicImitation wool, can feel stiffWarm, dries quickly, poor absorbency, used for knitwear and blankets

Woven

Woven fabrics use a warp and weft yarn on a loom to interlock fibres.

Plain weaveThreads are woven in a simple under one, over oneSimple and cheap, eg calico, strong and available in different thicknesses, when torn it rips in a straight line
Twill weaveTwill weave has a diagonal pattern on the surface as the weft yarn is woven over two warp threads in a continual patternStrong, hardwearing, denim has a white warp and blue weft resulting in a two-coloured fabric

Non-woven

Non-woven fabrics are webs of fibres that are glued, compressed or melted together.

Non-woven fabricPhysical propertiesWorking properties
Bonded fabricsFibres are visible and random, often has small holes on the surfaceDoes not fray as it has no grain, not strong
Felted fabricsRandomly matted fibres, often wool, available in many thicknesses and coloursFormed with moisture, heat and pressure, can be shaped as it has no elasticity or drape, used for hat making

Knitted

Knitted textiles made from rows of interlocking loops. They can be made from a variety of fibres, not just wool.

Knitted fabricPhysical propertiesWorking properties
Knitted fabricsCan be warp knitted (straight lines) or weft knitted (knitted upwards), available in a variety of textures and colours, can have patterns knitted in.Warm, stretchy and strong, tend to unravel when a hole is made, used in clothing and sportswear
