Modeling of the knitting process with respect to the optimisation of the construction parameters of warp-knitting machines
warp threads construction parameters working-in
font style='font-size:12px;'>
2009/6/17
In this article assumptions for the physical and mathematical general model of the knitting
process, referring to both iso- and anisostructural warp-knitted fabrics, have been defined.
In the course...
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...
Process of Lockstitch Tightening and Optimisation of Thread Working Conditions. Part II. The Trial of Optimising the Interlacement Location in the Stitch Link

font style='font-size:12px;'>
2009/2/12
During the formation of lockstitches in the sewing machine, the thread inserted into the stitch link by the needle undergoes extreme destruction as the result of the machine tool’s action. The stage o...
