Why is silk called Queen of fibres?

Silk is known as the Queen of all textile fibres because of its sheen and luster. It is one of the most beautiful and precious fibres given to us by nature and has been very much overshadowed over the past few decades by the other natural fibres and more particularly by synthetics.

What is silk made from?

In commercial use, silk is almost entirely limited to filaments from the cocoons of domesticated silkworms (caterpillars of several moth species belonging to the genus Bombyx).

Why is silk so smooth?

Sericin coats fibroin filaments so that they can stick together. One of the main factors that give silk its smooth texture is the removal of sericin from the silk fiber. This process is called degumming and makes silk soft and lustrous. When silk is not degummed, it can feel coarse rather than smooth.

What is silk waste used for?

The silk waste, a by-product of the reeling industry, is normally used for making floss silk, spun silk and noil silk. Besides, a huge quantity of silk waste is exported as such at a lower price. The export of any material, without value-addition is not in the best interest of the industry.

How is silk used in medicine?

Is silk still used today?

As a natural material, silk has a long history of human use and is still used for many textile applications today. As a natural material, it is sometimes seen as a preferable alternative to synthetic fabrics.

What is the structure of silk?

Silk fibers are composed of fibroin microfibrils assembled into filaments. Silk fibers consist of two fibroin filaments each produced by one of the worm’s salivary glands during spinning. Both filaments are then covered by sericin, an adhesive and hydrophilic protein to form the structural unit (Poza et al., 2002).

How is silk made?

Silk fibres are produced by silkworms when they spin themselves into a cocoon on their journey to becoming a silkmoth. These ultra-soft fibres are harvested from the cocoon in their raw state by being boiled in hot water (still containing the silkworms) and stirred until the cocoons unravel.

What are the applications of silk?

Silk fibroin can form porous 3D structures, namely sponges, foams, or scaffolds, which could be used for biomedical applications, such as tissue engineering, implantable devices, and disease models. Several techniques could be used to fabricate 3D SF sponges: salt-leaching, gas foaming, and freeze-drying [64].
