Occupational contact dermatitis in the workers employed in production of Texas textiles.

Pathological changes in the skin, of allergic type, have been detected in 35 of 131 weavers, employed in the production of primarily texas textiles. Patch tests yielded in 21 patients positive results with cotton and texas textiles. Approximately 50% of positive results of dermal tests have been found to be induced by naphthol compounds added to dyes in the process of preliminary dying. Moreover, 2 cases of extensive hyperchromatism in persons concerned with the above mentioned textiles have been observed which, due to the treatment procedures and removed from work in exposure have partly subsided.
