Analysis of compression property of height-alterable double-layer hollow tubular fabrics for industrial textiles

Tubular woven fabric can maintain a certain two-layer hollow height-alterable structure by heat setting, which quickly and effectively fills various materials, especially for the soft down feather. Therefore, by designing the pattern structure, a variable structure tubular fabric was designed and prepared by weaving equipment. We obtained a two-layer hollow height-alterable fabric by the heat-setting method and constructed a compression theory model. The compression process designed in this paper is the bending process of the fabric, so the bending deformation can be simplified into that of an elastically bent elastic rod. The results show that the theoretical curve and the actual compression curve are more consistent in the compression within strain 50%. The influence of key structural parameters on the compression performance of tubular fabric was also studied. On the basis of the model, the influence of material properties on the compression performance of tubular fabric was also discussed. The paper can provide theoretical guidance for the development of tubular fabrics with high hollow ratio and compression resistance in industrial textiles.
