In order to understand fabrics and how to use them, we have been asked to identify what fabrics Westwood uses in her collections, focusing on one garment in particular. We are interested in particular in the way it is produced and its properties.
The garment I have chosen is from Westwood's gold label, made from an 'interesting' gold fabric...

Fibre content: 61% viscose, 27% polyester; 12% PM; Combo 1: 100% cotton.
Viscose - A mixture of both man-made and natural components.
Production: It is produced from wood cellulose acetate treated with caustic soda. Viscose can also be made into the more common form of rayon that is used for many types of textile products, including clothing.
Properties: Viscose rayon has a silky appearance and feel, and also has the ability to breathe in a manner similar to cotton weaves. One of the more popular properties of viscose rayon is that the fabric tends to drape very well. One of the disadvantages to textile products made with viscose rayon is that the items will wrinkle very easily
In the burning test, Viscose burns similarly to cotton. It ignites quickly with a large bright yellow flame. The odour smells like burnt paper, and the ash is light and feathery grey.

Polyester - A manufactured product made from synthesized polymers.
Production: To make polyester, ethylene glycol and dimethyl terephthalate are mixed together. The chemical reaction results in bisterephthalate. This substance is heated to 270° Fahrenheit (132° Celsius), where it reacts again to form polyethylene terephthalate. To make polyester fiber, an extruder is used to produce very fine threads of PET. The fibres can be knitted or woven; they are mostly knitted to maximize the flexibility of the fabric.
Properties: A strong and durable synthetic fabric. Polyester dries quickly and can be washable or dry clean only. It is not the easiest fabric to remove stains from, and doesn't breathe as well as other fabrics may.
Burns slowly and melts when burning. May melt and pull away from small flames without igniting. Melted area may drip off clothing carrying flames with it
Poly - Viscose blend: The thermal insulation and water-vapour resistance increase with the increase in polyester content. Polyester is often used as a blend with other fabrics to lend wrinkle resistance
PM - I don't have a clue what this is, and can't seem to find out either. I'm going to assume it's the surface treatment that gives the fabric the gold shimmer.
