Silk is a very fine proteneous filament fiber. This soft fiber is made from silk warm which scientific name bombyx mori lives through eating mulberry leaves. These warm makes cocoons during their life which made with gummy substance sericin and it is a protein. Silk fiber was first found in China and afterwards it spreads worldwide, even in Bangladesh. Production process of silk fiber is known as sericulture and it is divided into two parts 'mulberry cultivation' and 'silkwarm'. In silk industry it is mentioned as two types of silk, one is mulberry type and another is non mulberry type. Non mulberry type silk is again divided into three sub categories. They are Tassar, Eri and Muga. In our country mulberry type silk is produced mostly. Silk is a protein fiber composed of fibroin, sericin, fats & waxes and mineral salts as a little part.

There is no any clear cut information about growing of silk industry in our country but Silk has a long glorious history in Bangladesh. After partition in 1947, majority of these industry listed into India except only 10 percent left in Bangladesh. In this time only two sericulture nurseries were established in Rajashi zones with only 2000 manpower. In the view of expanding these industries and make cash Bangladesh Sericulture Board (BSB) was established in Feb, 1978 in the silk city Rajshahi. Also a silk research institute was also established in this city. Now Rajshahi is renowned for making cloths from silk (from raw silk, hard silk, spun silk) fiber which is much demand full across the whole country as well as abroad.

Mulberry is a highly economic multipurpose usable plant. It is common name of the group heterozygous and growing species of genus morus of the family moracea. In Bangladesh mulberry plant cultivates particularly in Rajshahi division. Silkwarm is grown under a life cycle Moth-Egg-caterpillr-pupa . Caterpillr eats mulberry leaves and make cocoons rounded their body with a gummy protein sericin. After collecting cocoons it needs to boil and some other successive steps, as a result silk fiber is collected as thousand meter long and very soft.

A wide variety of products are made from silk fiber. Silk enable to contain about 11 percent moisture from atmosphere. It protects human body from outside environment, that is why is used to make warm apparels. From hard silk Georgette,  siphon and crape fabrics are produced. Decorative fabrics are produced from Tassar silk widely. pile fabric, dress material. linning, velvet and insulative materials are also produced from spun silk.
