Can you accurately identify fabrics by burning them? Not always, as many fabrics are different blends, but you can use the following as a rough guide – eg. if your ‘pure silk’ burns and melts, then it is certainly not silk. Pure cotton burns steadily with a smell like burning leaves, and leaves soft ash. Linen takes longer to ignite, and the unburnt cloth hardens as the flame approaches. Both fabrics can be blown out easily. Pure Silk is not so easy as cotton to extinguish, and burns with a smell like scorched hair, leaving ash, which easily disintegrates. Synthetics such as Acetate, Acrylic, Nylon and Polyester burn and melt, leaving a harder ash. Rayon burns rapidly, and leaves only a slight ash. If you do this, always use tweezers over a safe container, egg. a metal bowl with water and don't let children experiment, as nasty burns can result from some synthetics which burn and melt, dripping on to unsuspecting fingers.
What does the “Super” mean as in “Super 100’s” wool? This is a term originally created by the British Wool Textile Export Corporation. It refers to the degree of fineness, or more precisely, the length of fibre that can be spun from a pound of wool, i.e, the finer the wool, the greater its length per pound. It is now measured by thickness in Microns, a micron beinga thousand of a millimetre. As a comparison, a human hair is about 50 microns in diameter, and the average sheep wool about 25 microns. The ‘Super’ scale is roughly as follows: Super 80’s 19.5 microns The higher the ‘Super’ rating, the finer the cloth, and the more expensive it becomes. |
