A theoretical analysis of fabric deformation during wear is made using Wilkinson's concept of a hydraulic deforming force. It is shown that in practical situations the fabric-bending deformations differ substantially from those imposed in current standard wrinkling tests.

The seam slippage in woven fabric products is an adverse event in sewn products. The purpose of this study is to examine the seam slippage in chenille fabric products which are widely used as upholstery fabrics and to research ways to decrease seam slippage. In this study, the theoretical analysis of the seam slippage mechanism has been performed by the literature analysis and the results of experimental studies which were obtained in Part I. In this analysis, seam slippage is examined as the sum of two factors: the deformation of sewing stitch and the slippage of the fabric yarns by sewing stitch chains. According to the theoretical analysis of the processes, it can be inferred that it is possible to decrease seam slippage by driving the energy of applied mechanical forces to other tasks. Based on the results, the ways to decrease seam slippage, which occur in sewn products, have been determined. Two of them are related to the selection of sewing yarn and sewing parameters based on previous researches. The dependence of the other two ways on the fabric structure supported with adhesive interlining and the selection of sewing type were examined. The results of the experimental studies supported the results of the theoretical analysis.

Spherical Plain Bearing

The major failure mechanism of typical spherical plain bearings with self-lubrication is the wear of the woven fabric liner, which is an orthotropic composite of different elastic properties in different directions. The elastic properties of the liner are required for studying the tribological properties of the spherical plain bearings. This paper aims to develop an elastic property analysis model suitable for three commonly used fabric liners through a theoretical analysis of the elastic properties in order to obtain the parameter expression of the compliance matrix. The influence of the elastic properties on the wear depth of the spherical plain bearings is further investigated. Suggestions are made for the optimal design of the spherical plain bearings based on wear reduction.

Technical textiles used in airbag are usually in tight structure and subject to high air pressure in through-thickness direction. The pressure can deform fabric with changing its properties such as porosity and air permeability. This paper proposes an analytical approach to predict the out-of-plane deformation of tight fabric by analogy with membrane deformation. The model integrates the energies happened on the deformed fabric, that is, fabric strain energy, bending energy, and external work done. The fabric deformation can be predicted by minimizing the total fabric energy. The prediction was validated by experiment for fabric profile and the maximum displacement, and a good agreement was found for the cases of two typical fabrics. A sensitivity study shows that Young's modulus and Poisson's ratio can affect the fabric deformation significantly.

AbstractWoven compression bandage (CB) is one of the elastic textiles that exert pressure on muscles. With a defined tensile strength, it is possible to create the required compression on the given body parts. This work aims to investigate the relationship between woven fabric deformation, porosity, and tensile stress properties of three main types of woven CBs. All bandage samples are applied on human leg using two- and three-layer bandaging techniques. Bandage porosity is calculated for all frames at different weave angles using NIS software. Woven bandage construction parameters which are given by the preparation of warp and weft yarns, twist, count, and density along with woven fabric weave, type of weaving, and finishing process are the main factors that influence the bandage properties. Several methods considering thread distributions have been developed to determine the woven fabric's porosity during the tensile stress. Experimental results confirm that bandage porosity is directly proportional to the bandage extension and weave angle that ranges from 44° to 90°. The novelty of candidate study is to introduce practical remarks to the patient for optimizing the required bandage pressure by suitable extension or applied tension or weave angle for two- and three-layer bandaging systems.
