Study of the chemical treatment on cotton fabrics to increase the UV protection and anti-odour retention properties

There is a heavy demand for cotton materials in diversified areas,and the research works on them are increased tremendously in the recent days. chemical treatment of cotton cellulose without changing their fibrous form is a common practice in the textile industry. in this paper,cotton (woven and knitted) fabrics are selected and reacted with sodium hydroxide,morpholine or cellulase enzyme. the fabrics are then dyed by 6 different natural dyes: annatto,onion,pomegranate,indigo,myrobalan,barberry; and 2 synthetic dyes (reactive and sulphur dyes) and subsequently finished. the fabrics are then studied for their dyeing characteristics (k/s value),antibacterial activities,anti-odour and uv protection behaviour.
