Silk and their Properties

 

Silk and their Properties:

It is made from the fiber, or filament, composing the cocoon of the silkworm.

- Makes a soft, supple, strong and lightweight fabric, warm and sheer.

- Silk is the strongest natural fiber, makes sheer yet durable fabrics and can be blended with many fibers, including cotton and wool.

It is difficult to distinguish real silk from rayon viscose – so the ‘Silk Mark’ was launched on 17th June 2004 by Central Silk Board (Ministry of Textiles) and the Government of India to certify genuine silk.

The process of unwinding the filament from the cocoon is called reeling. 3 to 10 strands are reeled at a time depending on the diameter of the yarn required. The usable length of the reeled filament is 300 – 600 mt.

Short lengths of inferior silk filaments obtained from the waste material are carded, combed and spun into yarn much like cotton or linen. Spun silk fabric tends to become fuzzy because of the short staple.

For 100% spun silk the yarn count definition is the same as cotton – the Ne being the number of yarn hanks each 840 yards long which make one pound of yarn.
