This paper introduces a very simple way to evaluate low stress shearing properties of woven fabrics with the advantages of simplicity and easy accessibility. A 200-gram load is applied on small portion of the sample instead of applying the load overall width of the fabric. As a result, buckling of the fabric will happen and the loading-unloading curve will show the behavior of the fabric during...

The aim of this paper is to study the effect of silane treatment on woven banana fabric based unsaturated polyester resin composites. The fabric was treated with vinyl triethoxysilane. Woven banana fabric (WBF) reinforced unsaturated polyester resin (UPR) composites were fabricated by hand lay-up technique. The fabric content in the composite was kept constant to 35 %. The variation in the mech...

This work presents a computational material model of flexible woven fabric for finite element impact analysis and simulation. The model is implemented in the nonlinear dynamic explicit finite element code LSDYNA. The material model derivation utilizes the micro-mechanical approach and the homogenization technique usually used in composite material models. The model accounts for reorientation of...

Fabrics are pliable, breathable, lightweight, ambient stable, and have unmatched haptic perception. Here, a vapor deposition method is used to transform off-the-shelf plain-woven fabrics, such as linen, silk, and bast fiber fabrics, into metal-free conducting electrodes. These fabric electrodes are resistant to wear, stable after laundering and ironing, and can be bodymounted with little detrim...

The objective of fabric inspection is to ascertain whether the fabric received is of expected Quality standard or not. The main objective is detection of fabric defects as early as possible so that time and money are not wasted in the manufacturing, process. The ultimate goal of any quality control activity in clothing' industry is to satisfy the customers. Most defects in cloth occur while it ...

Automatic inspection of woven textile fabric is discussed. Two signiicant problems are addressed: (a) texture feature extraction; Fourier transform features are found to be well matched to the spatially periodic nature of the woven pattern; moreover , they are shift invariant; (b) detector design; maximum likelihood type detectors are inappropriate since we cannot hope to enumerate all defect c...

Defects are generated in woven fabric due to improper treatments in weaving machines, spinning errors and inadequate preparations of fiber at the spinning stage. The economic viability of a weaving plant is significantly influenced by the extent of its success in eliminating defects in fabric. Detection of defects is generally carried out by time consuming and tedious human inspection. Such man...

Abstract Digital image processing techniques are applied to perform an automatic method for the objective measure of woven fabric’s cover factor. Based on a frequency domain analysis, digital images of woven fabric samples, obtained with a camera assembled to a microscope, are cropped to enclose the maximum integer number of warp and weft periods and leveled for non-uniform illumination.
