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...

We consider a new kind of computational device like Turing machine, so-called circular Post machines with a circular tape and moving in one direction only, introduced recently by the second and the third authors. Using 2-tag systems we construct new nine small universal machines of this kind.

In this study, the performance properties of blankets produced by acrylic pile yarn via Raschel warp knitting machine are investigated. Two different counts and three densities used for yarns sample blankets. addition, treated with softeners. The structural properties, thermal comfort, softness durability eighteen samples tested according to international standards. aim study is select optimum ...

Abstract. Though the level of machine digitization in flatbed-knitting (FBK) today is high, design and development knittable data sets are still currently very time-consuming, digital simulations methods calculation expensive insufficient terms accuracy fit technical properties. Knitting process retrofitting activities executed mostly manually by an operator on basis operator´s experience. This...

A low-quality unwinding process of the machine can lead to downtime knitting and loss fabric quality. To address this issue, we studied tension vibration carbon fiber yarns during unwinding. Based on theory axially moving strings, dynamic model yarn was established process, bringing parameters into simulation. According simulation results, in is closely related spring preload, which needs contr...
