Proteins are large molecules consisting of chains of amino acids, which are essential components of the structure and function of all organisms.


Crystallization is a term used to describe the method for transforming a solution into a solid, where a supersaturated solution nucleates the solute by a chemical equilibrium controlled process.


Hydrogels made from reprocessed silkworm silk, a gel formed with aqueous solutions of the fibroin prepared as outlined earlier. The rate of sol-gel transition is directly dependent on temperature (higher the temperature the more rapid the gelation), pH (lower the pH the more rapid the gelation), and solids content (higher the solids higher the rates of gelation.

Jute fibre

Jute fibre is the name given to the tissue found to certain plants, which grow principally in India, and the East Indian Islands. The common jute comes mainly from Bengal, the province east of India, where it was first known to science around

Filament fibres

Filament fibres having a practically unlimited or infinite length are called filaments. Filament fibres are continuous (long) fibre. It may be natural like silk or synthetic like Nylon. Filament fibres are measured in yards or meters.


Velvet is a fabric with a short, tightly woven pile, originally made of silk; it is today made of rayon, nylon, acrylic and cut pile fabrics.

Staple fibre

Staple fibre has short fibre, typically measured in inches or fraction of inches, like those naturally found in cotton and wool. Silk, however, is the only natural fibre that does not come in staple lengths but instead in filament lengths.


Silk is the filament secreted by the silkworm when spinning its cocoon And the name for the threads, yarns, and fabrics made from the commercial silks products the cultivated silkworm, Bombyx mori, which feeds exclusively on the leaves of certain varieties of mulberry trees
