We present a framework for knitwear modeling and rendering that accounts for characteristics that are particular to knitted fabrics. We first describe a model for animation that considers knitwear features and their effects on knitwear shape and interaction. With the computed free-form knitwear configurations, we present an efficient procedure for realistic synthesis based on the observation th...

In this study, an appropriate fabric weight content controlled by the density of the warp and weft fibers is determined for biaxial warp-knitted composites referring to mechanical test results. Six different types of composite panel with two different fabric weights (813 and 1187 gr/m) and with three different stacking sequences [90we/0wa/90we/0wa]s, [90wa/ 0we/90wa/0we]s, and [90wa/0we/90we/0w...

Most practical textile models are based on a two scale approach: a one-dimensional fiber model and a fabric model, see [1]. No meso-level is used in between, i.e. the yarn scale is neglected in this setup. For dense textile substrates this seems appropriate as the yarns connect everywhere, but for loose fabrics or scrims this approach cannot be kept. Specifically when one is interested in track...

Cloth is an important material to model and simulate correctly, both in computer graphics and other industrial applications. The commonly used models for cloth in computer graphics typically approximate the cloth as an elastic sheet with linear isotropic behavior inspired by the construction of woven fabrics. However, they do a poor job of predicting the behavior of knits, which are driven by t...

The increasing demand for technical textiles makes innovations and acceleration of processes necessary. This research paper presents an innovative knitting technology. technology, which was funded by the European Regional Development Fund as R&D-project (EFRE-0400310), reduces production time creates completely novel structures. introduces validation process technology therefore brings theo...

In recent decades, electromagnetic wave pollution has become more and serious. order to reduce the adverse effects of these waves, nickel–iron/polymers p-phenylene terephthamide (PPTA)–blended single yarn plied were manufactured, nickel–iron fibers with various contents (10%, 15%, 20%) as raw materials used. Nickel–iron/PPTA-blended yarns knitted three knit structures looped deep (11.25, 11.50,...

This article presents an experimental investigation carried out to understand the mechanical behavior of composite materials made of 3D stitched woven-knitted basalt fabrics. The innovative preforms used consist of two outer layers of a plain woven fabric combined with two inner layers of weft-knitted fabrics. The weft-knitted fabrics selected for the study were varied plain knit, 1 × 1 rib, Mi...

ANY MATERIAL COMPOSED OF FIBRES IS A TEXTILE, AND THIS DEFINITION covers an extremely wide range of products in everyday use. Worldwide, over 35 million tonnes of textile fibre is consumed annually, ending up not only as clothing, upholstery, bed linen and carpets, but also in such items as ropes, seat belts, nets, road stabilisation mats, drainage pipes and tents. It is not surprising that, wh...

This paper deals with a problem of major concern to the knitting industry, which is fabric defects. When a defect occurs, the knitting machine has to be stopped and the fault corrected, thus resulting in time loss which is uneconomic. Eventually, the knitted fabric may be rejected if quality requirements are not met. An effective monitoring of the knitting process is required in order to avoid ...

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.
