6.5-6.8 Textiles: stock forms, processes, specialist processes, treatments GapFill

Textiles come in many different stock forms, depending on material type. Fabrics are sold by the metre on  blocksdenierrollsweights.   Standard widths of rolls are  150 cm, 200 cm, 250 cm100 cm, 150 cm, 200 cm110 cm, 110 cm, 110 cm, 110 cm90 cm, 137 cm, 154 cm.    WeightBlockRollDenier is the unit of weight used to describe fabrics.   

To work out how much material is needed, the area is calculated. Usually the shape is fitted in the boundary of a rectangle or square. The calculation used is  2 x width x heightwidth x height2 x width x 2 x heightwidth / height.  

Textile products can be made bespoke, at a  masscontinuousbatchone-off production scale. These tend to be hand-crafted and more expensive. Shaping tools such as  rulersscissorsshearsstamps would be used to cut or trim the material.    ContinuousMassBatchPrototype production is when many of the same items are produced in a set amount. This is seen in seasonal clothing. Digital manufacture can be used for this due to the scale.  Laser cutters3D printersCNC millsLathes are an example of using CAM to produce items at speed.   A technique that can improve the consistency during continuous or  massbatchone-offprototype production is quality control checks. This technique will reduce waste and ensure a high quality is met.    StampsHeating elementsShearsExtrusions are hot blades that can be used to cut through synthetic fabrics, such as   a hot knifea soldering ironan ironan oven.   Patterns and  quality control checkstolerancesstampstemplates are techniques that are used for high-quality production scales. They ensure consistency and precision.   Marking out methods are good ways of maintaining high quality for textile products.  Reference pointsSet squaresJigsRulers are an example that can be used in   all scales ofone-offbatchmass production.
