INDIA: Plasma technology abets angora cottage industry
Angora, the rabbit fibre is infamous for its soft feel, silky touch and heat insulating capabilities. The smooth surface of the fibres generates electrostatic charges which makes its processing cumbersome and tedious.
Furthermore, it is impossible to weave a 100% angora yarn. The National Institute of Design (NID) in collaboration with Institute for Plasma Research (IPR) has developed a prototype plant for atmospheric pressure plasma processing of angora wool.
This plasma treatment reduces the denier and increases the tenacity of angora fibres. The plasma etching increases the friction and cohesion between the fibres enabling to weave 100% angora fabrics.
This is the first atmospheric pressure plasma system for textiles developed in the country, and is cost effective. A patent has already been filed for this technology.
