Smart Textiles Production

The research field of smart textiles is currently witnessing a rapidly growing number of applications integrating intelligent functions in textile substrates. With an increasing amount of new developed product prototypes, the number of materials used and that of specially designed production technologies are also growing. This book is intended to provide an overview of materials, production technologies, and product concepts to different groups concerned with smart textiles. It will help designers to understand the possibilities of smart textile production, so that they are enabled to design this type of products. It will also help textile and electronics manufacturers to understand which production technologies are suitable to meet certain product requirements

Effect of knit and print parameters on peel strength of hybrid 3-D printed textiles

The influence of knit fabric structure on the adhesion of three-dimensional (3-D) printed textiles was examined. 3-Dprinting was applied to different elastic knitted fabrics with different amounts of prestretch, typical for 4-D fabric construction. The quality of the bond was measured in terms of peel strength. Peel strength was measured by pulling the fabric at 180 degrees from the printed plastic to delaminate the 2 and recording the 10 highest peak values observed during the test. The printed width, the ratio of fabric width of print width, fabric washing, and fabric structure were varied. The specimens were then evaluated for peel strength

Eine Gestaltungsmethodik für 4D-Textil

Today, electronic sensors, digital controllers and motors as actuators are required for the function of many technical systems that react to stimuli. 4D structures can replace these construction principles with reduced complexity. In hybrid manufacturing processes the advantages of textile manufacturing processes can be combined with the advantages of generative manufacturing processes. What is new is the purposeful change in shape of the hybrid material over time as a result of the interaction of a prestressed, anisotropic textile carrier structure and printed heterogeneous beam structures as reinforcement. The hybrid material 4D textile is validated on four application examples (gripper, glove, orthosis, sportswear)

Auxetic structures from 3D printed hybrid textiles

Auxetic structures have been produced using 3D printing and knitted textile materials. A review of other auxetic textiles is presented along with the new materials. A range of configurations were developed, prototyped, and tested to demonstrate significant auxetic response, including Poisson’s ratio up to negative one. The concept of 4D textiles was employed to create environmentally responsive hinges in some structures, allowing the material to change shape in response to thermal stimulus
