In order to mathematically describe the washing relaxation of knitted fabrics from manmade fibres, we performed different experiments with 50 - 100 washing cycles. While washing with detergent was shown to lead to a logarithmic increase in the fabric width, washing without detergent leads to an approximately linear increase in the fabric width, which can be transferred into logarithmic behaviour after...
Dla możliwości analizy stosowanego systemu obliczeń wykonano wstępnie pomiary współczynnika konwekcji naturalnej dla dzianin bawełnianych o splocie płaskim za pomocą układu zaprojektowanego przez autorów. Następnie zaprojektowano model dzianiny i zastosowano programy komputerowe do przeprowadzenia obliczeń. Dzięki porównaniu wyników uzyskanych z doświadczeń i obliczeń stwierdzono, że obliczenia wiernie...
Based on Laplace's law and the mechanical characteristics of knitted vascular prostheses, mathematical models have been developed enabling one to determine the values of the relative circumferential elongation, circumferential forces and standard circumferential susceptibility of a prosthesis as a function of its diameter and internal pressure. The results obtained refer to the values of the parameters...
The aim of this work was to predict the bagging fatigue percentage of knitted fabrics produced from viscose/polyester blended rotor yarns using blend ratios and structural cell stitch lengths as predictor variables. A simplex lattice design was used to determine the combinations of blend ratios of the fibre types. Knitted fabrics with three different structures were produced from viscose/polyester...
