3D HOLLOW FABRIC PRODUCTION WITH MODIFIED DOBBY SAMPLE WEAVING MACHINE

3D fabrics, also known as three-dimensional textiles are fabrics beyond the flat surface typical of traditional fabrics. A variety of methods, such as knitting, weaving and even braiding, are used to manufacture these textiles. This research aims to present a unique sample weaving machine made especially for creating especially 3D hollow fabric. For this aim, in the study a modified sample dobby weaving machine specifically tailored developed for the production of three-dimensional (3D) fabrics. The sample weaving machine incorporates a multi roller warp let off system designed for the production of 3D woven fabrics. This multi-roller warp-let off system facilitates the production of 3D woven fabrics by letting off and rewinding the warp yarns during the weaving process. Subsequently, this sample weaving machine was utilized to fabricate tubular and honeycomb 3D fabric structures. Consequently, 3D composite materials produced using these structures exhibit remarkable strength, lightness, and energy-absorption properties. In future studies, the aim will be to manufacture three-dimensional woven fabric structures with built-in impact protection features, eliminating the need for sewing.
