Muslin: Gossamer of the East
Muslin: Gossamer of the East “The fineness of the cloths is difficult to describe, the skin of the moon removed by the executioner-star would not be so fine. One would compare it with a drop of water if that drop fell against nature, from the fount of the sun… it is so transparent and light […]
Thermal Properties of Polymers | Melting Point and Glass Transition Temperature
Thermal Properties of Polymers In the amorphous region of the polymer, at lower temperature, the molecules of the polymer are in, say, frozen state, where the molecules can vibrate slightly but are not able to move significantly. This state is referred as the glassy state. In this state, the polymer is brittle, hard and rigid […]
Identification of Textile Fibre
Identification of Textile Fibre A: Burning Test :- Textile fibres can be identified by observing the burning phase of these fibres in flame . All natural and regenerated fibres are burnt to ash and special smell is observed for each fibre. Synthetic fibres on burning contract and form beads. All cellulosic fibres such as jute, […]
