    Identification of wearing comfort of the textile uppers of commercial footwear
    (Wydawnictwo Politechniki Łódzkiej, 2022) Kaziur, Patrycja; Mikołajczyk, Zbigniew; Matusiak, Małgorzata
    Knitting technologies have contributed to the production of textile footwear not only to reduce waste, but also to increase their physiological comfort. In this study, the functional properties of twelve commercially available knitted uppers and two footwear leathers were identified. For each of the tested variants, the following parameters were determined: thickness, mass per square meter, air and water vapor permeability, and selected parameters related to the thermal insulation and moisture sorption. On the basis of conducted research, it was shown that the best parameters were characteristic for knitted fabrics with jacquard weaves produced on cylindrical crocheting machines of large diameters.

    Influence of stretching on liquid moisture transport in knitted fabrics
    (Wydawnictwo Politechniki Łódzkiej, 2022) Matusiak, Małgorzata; Froschauer, Sabrina
    Moisture management in clothing is defined as the transfer of moisture from human body to the environment through the clothing [1]. Water vapour and liquid water (perspiration) need to get away from the human body to outside to keep the body dry. This action should happen immediately to have the maximal comfort of clothing usage. The aim of work was to investigate the liquid moisture transport in the knitted fabrics for babies and children clothing. Three variants of fabrics were the objects of the investigations. Measurement of the properties characterizing the liquid moisture transport in fabrics have been performed by means of the M290 Moisture Management Tester (SDL Atlas) [1,2]. Fabrics were tested in the relaxed and stretched state. Stretching of fabrics was realized by using the MMT Stretch Fabric Fixture device [3]. The percentage of stretch was adjusted at 15 %. On the basis of the results the knitted fabrics were compared in the aspect of their ability to ensure a physiological comfort. Influence of stretching on the parameters characterizing the liquid moisture transport in the fabrics was statistically analyzed and discussed.

    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.
