Influence of a Woven Fabric Structure on the Propagation Velocity of a Tension Wave
woven fabrics bulletproof vests anti-impact properties geometrical structure
2009/2/16
This article presents the results of research into the propagation velocity of a tension wave in a woven fabric with dependence on the parameters of its structure, such as the weave and the density of...
Optimisation of Needle Penetration Velocity Using the Link Drive Mechanism in a Sewing Machine
sewing machine link drive mechanism optimisation penetration velocity
2009/2/13
Needle movement in a standard lockstitch sewing machine is produced by a slider-crank mechanism. The needle moves in a vertical plane and penetrates the fabric on its way down. Friction between the ne...
Method of Estimation of the Tension Wave Propagation Velocity in Flat Textile Products
flat textile products tension wave propagation velocity wave propagation velocity
2009/2/7
When considering the anti-impact applications of flat textile products, we must take account of the effect of a tension wave on the product’s structure. Such a wave forces the creation of fast-changin...
