Effect of Different Interlining Types on the Mechanical and Thermophysiological Performance of Shirting Fabrics

This study evaluates the mechanical durability and thermophysiological comfort performance of different interlining types used in the collar region of shirting fabrics. Three plain-woven shirting fabrics (S1 - S3) were combined with six different interlining types (woven, knitted, and nonwoven; sew-in and fusible applications), and the performance of the resulting composite structures was analyzed. Mechanical properties, including tensile strength in warp and weft directions, bursting strength, adhesion strength, and bending rigidity, as well as comfort-related parameters such as air permeability, thermal resistance, and relative water vapor permeability, were measured. The experimental data were statistically evaluated using two-factor ANOVA. The results indicate that interlining type is generally a more influential factor than fabric type for most performance parameters. Woven interlinings demonstrated higher performance in linear tensile strength, whereas elastic knitted interlinings provided advantages in bursting strength. Fusible interlinings, applied under higher pressing parameters, produced greater adhesion strength and thermal resistance; however, they reduced air and water vapor permeability. In contrast, the sew-in method offered a more balanced comfort performance. The findings highlight the necessity of optimizing the trade-off between mechanical stability and comfort properties in collar applications and provide scientifically grounded criteria for interlining selection in industrial shirt manufacturing.
