In this diploma thesis, the physical and mechanical properties were researched of terry fabrics with increased elasticity. Terry fabrics differ from other fabrics mainly due to the construction itself as it also has added looped warp which shapes the signature loop on the surface of terry fabrics on one or both sides. Terry fabrics are usually made from cotton yarns and have compact and inelastic structure. In the diploma thesis, analysis was conducted on different terry fabrics with increased elasticity which have different ratios of sheathed cotton yarns with PBT filaments core in the weft direction. Elasticity of terry fabrics is developed after treatment in boiling water due to the presence of the PBT filaments.
In the experimental section we conducted research on six terry fabrics, before and after treatment in boiling water, when elasticity developes. We analysed and determined basic physical mechanical properties of the fabric: density of warp and weft, warp and weft crimp, surface mass, fabric thickness, air permeability, tensile strength and elongation, bursting strength, abrasion resistance, absorbency was tested with capillary lift. The findings of the research showed us, after washing the surface mass increased due to crimping which lead to fabric thickness increasing as well. Air permeability decreased after washing in most samples. The breaking force in the warp and weft direction increased after wash in most samples, similar results occur with elongation. Bursting strength or the force required to crack the fabric was greater after the washing in most samples. The capillary lift showed the capability to absorb moisture has increased after the wash. When conducting abrasion resistance test, samples which were washed experienced bigger mass loss and their surface deteriorated quicker.
