| Summary: | The purpose of this research was to compare preshrunk and nonshrunk fabrics when fused to suitable weight interfacings by examination of rigidity, bond strength, and dimensional stability. More specifically, varying fiber content and three types of nonwoven interfacing were used.
Preshinking consisted of a warm wash and tumble dry Preshrunk and unshrunk fabrics were fused to each of the three interfacings using an industrial steam press. Selected performance properties were measured after 1, 5, and 10 laundering periods.
The data were subjected to a randomized complete block design analysis of variance to determine the significance cf main effects and interactions among variables. The .05 level of significance was used.
The four fabric types were different from each other. fabric had a significant effect on all of the dependent variables: rigidity, bond strength, and dimensional stability. The three types of interfacings, although different, were not as dramatically different as were the fabrics. The type of interfacing had a statistically significant effect on two of the dependent variables, flexural rigidity and bond strength, but, had no significant effect upon the dimensional stability. The preshrinkage of the fabric had an effect on the flexural rigidity and bond strength, but had no effect on dimensional stability when measured in the weft direction. Prewashed fabrics were found to be slightly more rigid and exhibited much weaker fabric-interface bonds than the control samples. Evidence from this research suggested that shirting fabric should not be preshrunk prior to garment construction. === M.S.
