The present study addresses the constitutive model of cloth using anisotropic hyperelastic materials and its implementation into a nonlinear finite shell element in order to simulate large deformation behavior of cloth. Present work focuses on a macroscopic continuum constitutive model able to capture the appropriate mechanical behavior of cloth, which is characterized by two families of yarns,...

This work presents a new highly automated artificial vision inspection (AVI) tool for real-time defect detection and classification on circular knitting machines based on the combination of statistical analysis, Image Processing and Radon Transform. The tool (software + hardware) is directly attached to a circular knitting machine and the inspection is performed on-line. The automatic inspectio...

The problem of unpredictable shrinkage of cotton knitted fabrics and garments faced by the industry has been investigated by knitting single jersey cotton fabrics using the similar yarn and knitting parameters as used in the industry and finishing them. Through linear regression analysis, the variable factors, which affect the shrinkage and should be included in the domain of the quality contro...

A need exists for artificial muscles that are silent, soft, and compliant, with performance characteristics similar to those of skeletal muscle, enabling natural interaction of assistive devices with humans. By combining one of humankind's oldest technologies, textile processing, with electroactive polymers, we demonstrate here the feasibility of wearable, soft artificial muscles made by weavin...

Woven fabrics prove to be a very convenient fibre reinforcement when prepreg layers have to be draped on to double curvature moulds. The process of draping causes the angle between the warp and weft yarns to vary over the product with this double curvature. As a result, the thermomechanical properties of the fibre reinforced composite material show a corresponding distribution. These thermo-ela...

One of the criteria for quality assessing of a garment by the consumer is durability. Resistance to pilling is one aspect of durability that controls the appearance of the product and a source of insatisfaction about the product. This paper presents state of the art pilling assessment techniques, with a view on the application of image processing for fabric pilling detection and measurement. Th...

The aim of this study is to investigate the influence knitting structure and metal wire amount on electromagnetic shielding effectiveness (EMSE) knitted fabrics comparatively. Single jersey, single pique, weft locknit, cross miss involving stainless steel or copper wires were produced a flat machine. A free space measurement technique was used for EMSE measurements in an anechoic chamber. varia...

A so-called inflatable beam is a membrane tube which gains its stiffness only by a prescribed internal pressure. Such lightweight structures are useful in inflatable buildings and particularly in space industry, whenever rapidly deployable and easily transportable structures are required. An inflatable beam may look like a standard beam, but its mechanism is quite different and a specific mecha...
