Abstract: 

In this paper, strength-generation mechanism of yarn interaction within woven fabrics is discussed and it is shown that the yarn pull-out test is an effective method to examine some of the mechanical properties of fabrics. The nature of internal frictional force is mainly related to yarn interaction at warp and weft crossing points. Since enzymatic hydrolysis removes most of surface fibres and pills and protruding fibres are mainly removed due to mechanical action during bio-polishing process, it is demonstrated that the finishing treatments especially bio-polishing cause the yarn interactions to be localized mainly on the weft and warp crossing points. Also, it was observed that the correlation between static and dynamic pull-out forces, intensity-generating mechanism of yarn interaction within the fabric, and the fabric mechanical properties (fabric shear hystersis and bending hystersis) are improved by bio-polishing.
