Comparing three brands of cotton T-shirts

This study compared three brands of T-shirts for selected structural and performance attributes. The impact was examined by brand and frequency of washing. Six null hypotheses were developed and tested using one-way ANOVA and t-test analyses. Standardized tests developed by AATCC and ASTM were used. All hypotheses were rejected. Differences were found for frequency of washing, use of standard and commercial detergent, and structural attributes including fabric count, thickness, and weight. For performance attributes, differences were significant for dimensional stability, pilling, and horizontal wicking. The results added new information to the knowledge base for textile analysis at the garment stage. Results supported some existing knowledge and refuted others. Implications for future research are discussed.
