Silk is a protein fibre from silkworms. It becomes weaker when wet also be damaged by sunlight, alkalinity, oxidizing, bleaches, and perspiration.
Silk Strengths And Weaknesses When Cleaned.
Silk is the strongest natural fibre. The smoothness of silk yarns reduces the problem of wear by abrasion. Weave can affect the finish fabrics strength.
While silk is an elastic fibre, its elasticity varies as may be expected of a natural fibre. What is amazing about the silk fibre is that it can be stretched from a seventh to a fifth of its original length before breaking. but problem is that when it returns to its original size gradually and loses a little of its elasticity.

Like wool, Silk is a protein fibre, therefore it is also a non conductor of heat.
The good absorptive property of silk also contributes to its comfort in a warm atmosphere. The reason and major factor in Silks ability to be printed and dyed easily is because Silk can generally absorb about 11% of its weight in moisture, but the range varies from 10% to as much as 30%.

It is a hygienic material because its smooth surface does not attract dirt and when dirt does gather it gives up readily by washing or dry cleaning. note silk is weak when wet. but will water spot easily,
Taffeta for example may be given a finish that could be permanently stained by water.
Reaction To Bleaches.
Mild bleach of hydrogen peroxide, or sodium perborate may be used with normal caution.
Because of the straightness of the filament, smooth surface silk fabrics have only a normal shrinkage.
