Development and validation of test method for determination of chlorinated organic carriers in textiles

Introduction:Chlorinated Benzenes and Toluenes generally called chlorinated carriers are a group of organic compounds having one or more chlorine atoms attached to either a benzene or toluene ring.Chlorobenzenes and Chlorotoluenes have diversified application in several industries including textile and footwear industries [1].Chlorinated carriers are typically used as intermediates or precursors in the manufacture of textile dyes and auxiliaries.It is also used in polyester dyeing as a dispersing and leveling agent [1].After dyeing, polyester materials are washed with water to remove unfixed dyes and carriers.However, trace amounts of carriers may remain as impurities in the final dyed materials.COC,s and their isomers have potential health hazards [2].These compounds are harmful and may induce lever malfunction, irritation to mucous membrane and skin.Due to the hazardous nature of these chemicals, many leading apparel and footwear brands have banned the use of chlorobenzenes and chlorotoluenes in the production a n d m a n u f a c t u r i n g o f t h e i r p r o d u c t s [ 2 ] .
