Auxetic fabrics have unique and astonishing properties, as they have a negative Poisson's ratio (NPR), unlike traditional fabrics. They possess distinctive features such as increased elasticity, which enhances comfort and allows for better movement. This research focuses on studying the effect of geometric pattern size on the NPR in uni-stretch auxetic woven fabrics (USAWF), aiming to achieve optimal results in terms of the fabric's NPR and overall characteristics. This is achieved through the use of a specific geometric pattern in two different sizes and the incorporation of both elastic and nonelastic yarns (EY and NEY) in the weft guidance, along with the use of tight and loose weaves (TW and LW) to create differential shrinkage and obtain auxetic fabrics. The NPR was evaluated through tensile testing of the produced samples. To measure the NPR, the tensile process of the samples was recorded using a high resolution camera placed on a stand in front of the sample. This allowed for precise measurement of changes in size in both the tensile and transverse guidance.
