Relationship between mechanical properties of bilayer textile systems and their components

Abstract

The goal of this research was to defme the relationship between the mechanical properties of fused bilayer textile systems and their constituent layers, i.e. fabrics and fusible interlinings. The objects of investigation were four samples of broken twill outer fabric different in thickness (1.01-2.28 mm) and mass per square metre (222-398 gW), and two types of fusible interlinings: nonvowen with longitudinal threads and warp knitted. Fused bilayer textile systems were created by changing the orientation of the fusible interlining by 0°, 45°, and 90° in respect to the outer fabric's warp direction. Mechanical properties (tensile, shear, bending, and surface properties) of fused textile systems and their components were determined using KES-F automated testing devices. The relationships z = z{x,y) between fused textile systems' mechanical parameters (z) and parameters of the outer fabrics (x), as well as parameters of fusible interlinings (y) in 0°, 45°, and 90° orientations were deñned. The obtained theoretical relationships were confirmed experimentally by fmding proper mechanical properties of fusible interlinings (y) on the basis of which bilayer textile systems with mechanical properties (z) falling into the allowable value range of the KES-F quality chart could be composed. Selection of compatible components for fused textile systems with certain mechanical parameters allows avoiding problems in garment manufacturing processes and predicting the appearance and quality of the fmal textile product.

The investigation of barrier and comfort properties of multifunctional coated conductive knitted fabrics

“…It can be concluded from the data presented in Tables 6 to 8 that the shearing characteristics of noncoated knitted fabrics of groups A and B are very close to the results of different knitted fabrics investigated by other authors [29][30][31][32]. Higher values of shearing rigidity are appropriate for coated fabrics [33].…”

“…The shearing rigidity of fabrics after coating increases approximately 6-8 times. Although, in terms of the article by Ancutiene et al, [29] where the object of research was woven fabrics, investigated fabrics of group A and B can be attributed to the high stiffness fabrics, but compared to other materials used for technical purposes, the shearing rigidity of even coated fabrics is not so high. For example, Lomov et al [34] received significantly higher values of shearing rigidity for uncoated fabrics.…”
