6.1-6.4 Textiles: sources, origins, properties, selection, impact of forces GapFill

A  rolllaminateblockdenier is a form of textile that has been backed with another material. This is typically polymer film that improves the properties. This is an effective method to strengthen the material against stresses.

Yarn is a solid ball or reel;   mahoganyplyoakash is the number of threads to make the yarn.  

Textile materials are stressed during production and use. For example, when wool is growing on an animal,  compression isnatural forces areshear istension is happening within the fibres.

When a piece of clothing is being worn, the  hardnesselasticityflexibilitytoughness of the textile is essential for it not to tear.

 CompressionShearTensionTorsion is the force that stretches a fabric. Some fabrics are more resistant to this type of force, such as acrylic.

 Stay stitchingHemmingRibbingLamination is a technique used to improve the tensile strength of a piece of fabric that has a naturally low resistance. This is done around the edge to help maintain the shape.  

 TensionShearCompressionTorsion is a force that affects a textile when it is being pulled in opposite directions. This could happen when a T-shirt is caught on something. Suitable methods of fabrication can prevent the material from being damaged.

For example, a twill weave is used in  denimvelvetjacquardcalico to provide a very strong reinforcement. If the material is torn in one place it will not affect the rest of the fabric very much.
