Investigation of Textile Fabrics Behavior under Compression

Abstract

Textile materials during manipulation or in garment formation processes tend to deform and loose their form stability
even subjected to low loading. Their deformation behavior is greatly influenced by combination of fabric mechanical
properties at low loads. In present paper the new attachment for the tensile tester is presented for the investigation of
fabric deformation behavior under compression; the construction and working principle of equipment is discussed.
Fabric deformation behavior is investigated compressing two types of specimens: pear loop shaped and plate shape. The
obtained load-deformation curves according to their characteristic parts are divided into different zones. Each zone is
defined by appropriate parameters. The KES-FB (Kawabata Evaluation System for Fabrics) system is used for the
measurements of low stress tensile, shear and bending properties. The relationships between the parameters obtained by
new equipment and parameters obtained by KES-FB system as well as with formability parameter are defined. The
obtained results revealed that deformation behavior under compression of plate and pear loop shaped fabric specimens is
greatly influenced by fabric structure, direction and mechanical properties and it gives the information about fabric
formability.
