    Identyfikacja warunków procesu dziania podczas kontrolowanego przeciągania zwrotnego nitki
    (Wydawnictwo Politechniki Łódzkiej, 2007) Kłonowska, Magdalena; Korliński, Władysław; Jurasz, Józef
    Identyfication of knitting process conditions has been performed on the base of knitting process computer model, during controlled robbing back of thread in the knitting zone on weft-knitting machines. The research was made for linear and non-linear cams with limited needle ascending height in the knitting zone for classical knitting technique as well as Relanit knitting technique. Experimental verification of research results has been made on measuring computer weftknitting machine, concerning threads loading in the knitting zone and sensitivity of knitted-in thread's length to initial tensions change. Construction parameters of optimal cams contours were defined for classical knitting zone and Relanit knitting zone.

    Modelling of the Knitting Process during the Knitting-in of Elastomeric Threads Using Knitting Machines with Relanit and Classic Knitting Zone
    (Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Pietruszewska, Renata; Kowalski, Krzysztof; Kłonowska, Magdalena; Kowalski, Tomasz Marek
    An analysis of the knitting process during the knitting-in of elastomeric threads using knitting machines with a Relanit and classic knitting zone was made on the basis of simulations considering a numerical model which takes into account the most important parameters of the knitting process, viscoelastic properties of the thread and geometrical parameters of the knitting zone. The conditions of forming stitches from classic cotton yarn were presented for comparison. The results of the simulation tests were verified experimentally on a computer-aided knitting machine with a classic knitting zone.

    Influence of Stress and Relaxation Characteristics of Knitted Fabrics on the Unit Pressure of Compression Garments Supporting External Treatment
    (Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Ilska, Anita; Kowalski, Krzysztof; Kłonowska, Magdalena; Kowalski, Tomasz Marek
    The paper presents an analysis of the influence of the mechanical properties’ heterogeneity of knitted fabrics and the method of determining their characteristics of stress and relaxation (deformation) on the value of unit pressure of compression garments. Changes in the value of force as a function of relative elongation were described by experimental dependencies for stress and relaxation phases for the 6th hysteresis loop, taking into account the confidence intervals. Model calculations were performed for a wide range of body circumferences G1 = 5 - 110 cm and for two values of unit pressure: 20 and 30 hPa using Laplace’s law and experimental functions determined which describe the relationship between force and relative elongation of a knitted fabric. The research indicates one of the reasons for changes in the unit pressure in the compression garments designed.
