Textiles: Sources and properties - EduqasLaminating and bonding

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.

Laminating and bonding

Laminated fabrics

fabrics are formed when two or more fabric layers are stuck together, usually with an adhesive (glue). If the fabrics are made from synthetic yarns (thermoplastic) they can be joined together using heat, melting the fabrics together, eg neoprene used for wetsuits.

Many wetsuits are hung to dry on a clothing rail.

Other examples include Gore-Tex, Permatex and Sympatex, all of which utilise the process of laminating to reinforce and stiffen the fabric.

Bonded fabrics

Bonded fabrics, sometimes called non-woven fabrics, are made from , not . This makes them much weaker and prone to tearing, but they don鈥檛 stretch or fray. They are generally used for products that are disposable, for example, wet wipes, J cloths and surgical gowns.

In the fibres are laid in a random pattern and are held together by adhesive (glue), or heated if made from synthetic fibres. Stitching the fibres together can increase the stability and strength of the fabric but is less common. , used to support and stiffen parts of clothing, is an example of a bonded fabric.
