Influence of process and structural parameters of elasticised knitted fabrics on loop length

Abstract

The purpose of the investigation was to study the loop length of the basic single and double weft knitted structures, made from elastane core-spun yarns (yarn diameter, loop width, loop height, loop length), compared to equivalent structures made from conventional yarns. Furthermore, the objective was to study the influence of structural and process parameters on the loop length. Knitted loop geometry is a very complex system. Beside the factors themselves (fibre type, yarn structure, knitted structure, knitted fabric density level and relaxation type), several two-factorial interactions, and some higher-order interactions are statistically significant. The most important influences are: density, structure, relaxation, and fibre type - yarn structure, yarn structure - relaxation type and fibre type - relaxation type two-factorial interactions. The relaxation type has much greater impact on loop length for the knitted fabrics with incorporated elastane than for conventional knitted fabrics, where this impact is negligible.
