A novel technique to minimise energy and pollution in the dyeing of linen fabric

Abstract
Garments made from linen fabrics have a natural feel and drape. Most commercially available direct and
reactive dyes have only a moderate affinity for this cellulosic fibre, although this lack of affinity can be
overcome by the use of electrolytes. As a result, high volumes of wastewater containing large amounts
of chemicals are discharged from the typical cellulosic material dyehouse. The ‘no-salt dyeing’ of linen
fabric with reactive and direct dyes was achieved by treating linen fabrics with chitosan in a microwave
oven. After using the novel dye method, no observed enhancement of either wash or light fastness
properties was seen. Dyebath reuse for both reactive and direct dyes was carried out in order to reduce
the environmental impact of the dyes. This dyeing method was then applied to dyeing linen fabrics, with
each of the items of clothing subjected to layout and cutting according to the design’s patterns; the
dyeing results are discussed in this paper.
