Development of an Automated Design Method for Manufacture of Fabrics of Defined Structure

Abstract

An automated method of designing technology for manufacturing fabrics of defined structure was developed. An algorithm was developed for calculation of fabrics of defined structure in designing the technology, consisting of determining the properties of the fibres used (tensile and compressive viscoelastic parameters, durability parameters, resistance to wear and repeated loads, hemicyclic characteristics); determination of the coarse fabric structure phase; calculation of warp and weft tension during frontal battening based on use of the linear theory of warp thread fibre tension in the “warp roller—dropper” zone and the weft thread pinch tension based on the linear theory of viscoelasticity; estimation of the loom threading tension using long-term strength criteria; determination of the maximum possible rotation rate of the main loom shaft; calculation of breakage of warp and weft threads based on the assigned properties of the fibres. Software was created for designing loom manufacture. The manufacturing process for production of an important number of fabrics was designed. The basic process parameters for manufacturing fabrics were determined.
