To detect defects in woven fabric a reduced coefficient fabric space is constructed, for which the principal components representing row and column wise data distribution of the training fabric sub images are determined with the help of a novel singular value decomposition based method. The size of this reduced coefficient fabric space is suitably optimized by particle swarm optimization method...

Auxetic metamaterials expand transversely when stretched longitudinally or contract compressed, resulting in a negative Poisson’s ratio (NPR). fabrics are 3D textile possessing unique geometry that can generate an auxetic response with respect to tension. In weft-knitted fabrics, the NPR property is achieved due inherent curling effect of face and back stitches knit loops; they organized knitti...

Cotton fabric was grafted with a poly (acrylamide-co-itaconic acid) co-polymer via ceric ammonium nitrate (CAN) induced graft co-polymerization in an aqueous medium. The grafted cotton fabric was loaded with Ag nanoparticles by entrapment of Ag+ ions into a grafted polymer network, followed by borohydride reduction. The resulting Ag nanoparticle-loaded grafted fabric was characterized by Fourie...

rehabiliating bushehr historic fabric and paying to it as an important urban fabric through increasing capabilities and facilities is main concern. bushehr historical fabric can be the consequence of several factors the most important of which is the persian gulf and its past history as a national one. this fabric, is organic, dense, compact, having its own characteristics. one of its main prio...

Recently, mesh networking and blockchain are two of the hottest technologies in the telecommunications industry. Combining both can reformulate internet access and make connecting to the Internet not only easy, but affordable too. Hyperledger Fabric (HLF) is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. We evaluate HLF in a real produc...

The quality of cotton and cotton/elastane single jersey knitted fabrics before after softening was evaluated through their mechanical properties, pilling, volume electrical resistivity. Elastane-containing have higher bursting elongation stiffness, lower strength, the same or pilling grade, 23–27% resistivities compared to 100% due increased compactness that enables better contact between loops...
