• Much like other silks, thermasilk requires special care to maintain its luster.silk 4 image by jbattx from Fotolia.com
  
  Thermasilk is a type of semi-synthetic fabric that combines the natural properties of silk with the latest synthetic fiber production technology to give superior thermal properties. It is made from pure silk and is strong and warm despite being thin and light. It is ideal for undergarments and sportswear, as it is soft, lightweight, durable and comfortable. Since it is a very delicate fabric, it needs intensive care. You need not dry-clean it every time; it can be washed at home, provided that it's done carefully.
  
  

Wash in Cold Water

• It is advisable to use cold water for washing thermasilk, as it helps the fabric retain its luster. Cool water can clean the garments just as thoroughly as warm or hot water. Make a soapy solution in a bucket or the sink with detergent and water and dip the garments in it.
  
  When washing thermasilk garments, take extra care on areas like the underarms of a shirt, which might require extra cleaning because of sweat.
  
  

Do Not Wring

• Dipping thermasilk garments in water with detergent for five to ten minutes is enough to release the dirt. A lot of agitation is not required, as this fabric releases dirt very easily. Wringing should be avoided because this might wrinkle the garment and give it a crumpled look.
  
  

Use Mild Detergent

• Since the fabric is very delicate and prone to damage by harsh detergents, mild detergents are preferred. Special detergents for washing babies' clothes can be used. When rinsing, change the water in the bucket or sink two or three times so that all the detergent is removed. Leftover detergent acts like an abrasive and reduces the life of the garment by making it prone to wear and tear.
  
  

Dry Flat and Avoid Dryers, Sunlight

• Don't hang thermasilk garments on lines or hangers to dry. Instead, lay them out on towels or a similarly clean and absorbent surface. Avoid excessive exposure to sunlight to protect the color and shine of the fabric. Avoid putting thermasilk garments in dryers, since dryers can damage the garments. If dried properly, thermasilk garments don't require ironing, and a smooth finish can be achieved simply by finger-pressing the seams. However, if required, use a warm iron. Hang the garments on padded hangers. Store them in a clean and dry place away from sunlight and moisture.
