Raw silk
Silk containing sericin is called raw silk. The gummy substance, affording protection during processing, is usually retained until the yarn or fabric stage and is removed by boiling the silk in soap and water, leaving it soft and lustrous, with weight reduced by as much as 30 percent.
Since raw silk is matte, it does not actually look like most silks. Imagine instead a coarser fabric that looks like a mix between wool and cotton. Naturally raw silk is milky white in color, but it can be dyed to create rich, vibrant garments.
The fabric has always retained its winning position in the world of fashion. There are different varieties which enhance the quality and the essence of a garment .
