Two‐component multilayered woven fabrics: weaves, properties and computer simulation

Presents general properties and examples of weaves for two‐component multilayered woven fabrics. Such fabrics have a combination of properties which it is difficult to achieve in traditional fabrics (bulk combined with good tenacity, high cover level with porosity), can be used in liningless garments and can cope with ergonomical restrictions when using fibres with special protective properties. Describes a CAD system which can be used as an aid for a technologist to choose yarns for warp and weft, fabric weave and picks/ends count to meet demands specified by a particular fabric usage. It employs a new method of coding of multilayered fabric structure; mathematical methods used are based on the mechanical model of yarns interaction in a fabric. This describes the spatial disposition of yarns which allows production of any desired images of fabric geometry, i.e. surface smoothness or shape of pores. Discusses the complex nature of porosity of multilayered fabrics.
