Identifying Fibres Silk


Silk is the strongest natural fibre. The smoothness of silk filament yarns reduces the problem of wear by abrasion.The strength of silk fabric is also affected. of course, by construction as well as its finish.


While silk is an elastic fibre, its elasticity varies as may be expected of a natural fibre. Silk fibre may be stretched from a seventh to a fifth of its original length before breaking. it returns to its original size gradually and loses a little of its elasticity.


Silk fabrics retain their shape and resits wrinkling well,

Heat Conductivity

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. Silk fibre can generally absorb about 11% of its weight in moisture, but the range varies from 10% to as much as 30%. This property is also a major factor in Silks ability to be printed and dyed easily.

Cleanliness & Washability

Silk 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. All Silk will water spot easily, Taffeta for example may be given a finish that could be permanently stained by water. Dry cleaning is preservable for all weighted silks and although wild and spun silks may be washed, this applies to loose pieces such as garments whereas with upholstery fabrics it would be safer to dry clean.

Reaction To Bleaches

A 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.

Effect Of Light

Continuous exposure to light weakens silk faster than cotton or wool. Silk drapery and upholstery fabrics should be protected from direct exposure to light.

Reaction To Acids

Concentration mineral acids will dissolve silk faster than wool. Organic acids do not harm silk

Reaction To Perspiration

Silk fabrics are damaged by perspiration. The silk itself deteriorates and the colour is affected causing staining. its best to get disclaimer signed.
