    Hydrostatic resistance dependence on the structure and the use of gradient measurement
    (Wydawnictwo Politechniki Łódzkiej, 2022) Tesinova, Pavla; Al-Azawi, Halim; Volek, Lukáš
    Hydrostatic resistance is an important property for outdoor fabrics as a shelter to the human body against the unfavourable outdoor environment. Rain, strong wind, snow attack human health and comfort feeling. Hydrostatic resistance can be described by the unit of the water column and measured by the standard ČSN EN ISO 811 [1]. Paper compare the behaviour of the two and three laminates in one study and two instruments in the second study. It was realised that measurement with the three laminate is balanced more if we apply pressure from the upper surface and inner surface. Two laminates membrane is not supported by the fabric if we apply water pressure from the upper surface. Hydrostatic resistance is significantly lower. Two instruments measurement is impossible to confuse in porous materials and lower fabric densities of water repellent fabrics. Durable fabrics and laminated fabrics need to be studied in the following study.
