This study was conducted to determine the effects on manual dexterity performance of two thickness of butyl, chemical protective gloves, 0.64 mm and 0.36 mm, and of two types of cotton glove liners, a seam-stitched and a sting-knit version. Over seven working days, 12 male subjects performed three, fine-finger dexterity tests while bare-handed and while wearing each of the four glove and liner combinations. The subjects also completed a questionnaire designed to elicit their opinions of the handwear. Analyses of the subjects times to test completion with the glove and liner combinations, expresses as a percentage of bare-hand times, failed to yield any significant interactions among the glove, the liner, and testing session variables. Also, the main effect of liner type did not reach significance, but the main effects of glove and of session did. the subjects performance improved across sessions and was better when the 00.36-mm gloves were torn than when the 0.64-mm gloves were used. Although the subjects expressed a definite preference for the thinner butyl gloves, they did not consistently choose one cotton liner as being superior to the other. When forced to select the one liner that they preferred, 8 of 12 subjects chose the string-knit version.
