Auxetic materials expand in at least one dimension, when stretched longitudinally i.e. they have negative Poisson’s ratio. Development of 2D woven auxetic fabrics (AF) is a new approach to develop mechanically stable auxetic textile structures. However, the mechanical response of such emerging structure is still not studied in detail yet, therefore different mechanical properties of 2D woven AF are compared with conventional non-auxetic fabric (NAF). AF was developed by orienting yarns in auxetic honey-comb (AHC) geometry and auxeticity is induced due to such orientation of yarns. AF was developed using conventional (non-auxetic) materials; cotton yarn and elastane cotton yarn in warp and weft dimension respectively, using air jet loom. Structure and auxeticity of AF were analyzed using a digital microscope and its different mechanical properties (tensile strength, tear strength, bursting strength, cut resistance, and puncture resistance) were studied. AF showed superior mechanical properties with a lower initial modulus, which is beneficial for different protective textiles applications like cut resistance gloves, blast resistant curtains, and puncture tolerant elastomeric composites.

In this research work, we have studied the dyeing behaviour of fabrics made from ring, rotor and MVS yarns. Thediscrete structure of respective yarns made by different spinning techniques have significant effect on dyeing behaviour offabrics. The fabrics were investigated for K/S values of polyester dyed, cotton dyed and polyester+cotton dyed fabrics andtheir colour fastness to crocking. The analysis of dyeing behaviour revealed that yarn manufacturing technique hassubstantial effect on the colour strength of their respective fabrics. Due to unique distribution of fibers within the crosssectionof yarn, the cotton dyed and polyester+cotton dyed fabrics made from MVS yarns exhibited better K/S values ascompared to other fabrics. The fabrics also exhibited a difference in colour fastness to crocking in dry and wet form. Thecolor fastness of fabrics to crocking in dry form were found higher than in wet form. The polyester dyed and polyester+cottondyed fabrics made from MVS yarns have shown higher color fastness to crocking.
