Fabric quality, which may be defined as the satisfaction obtainable from required performance properties manifesting themselves in fabric usage, is a consequence of its physical structure. It is imperative that this structure shoud be stable during a resonable life of the fabric. Principles of design to define fabric structure satisfying these needs are quite well known and computer aided fabric design applications are widespread. In the case of design of fabrics of complex structure, however, there arise many problems and the current computer aided design software may not be adequate to cope with them. In this paper some important problems encountered in the design of simple and complex fabric structures are discussed in general, based on relevant literature. Three examples are given how they may be solved mathematically in a suitable way for computer applications to obtain computer simulations of complex fabric structures such as double woven fabrics, woven carpets and rib knit fabrics.

“…Several works generate knit geometry using spline curves and focus on the plain knit stitch [Demiroz and Dias 2000;Göktepe and Harlock 2002;Choi and Lo 2003;Choi and Lo 2006;Renkens and Kyosev 2011]. Other research has looked at modeling representative cells of complex knitted fabric [Kurbak and Alpyildiz 2008;Kurbak 2009;Kurbak and Soydan 2009], but depending on the pattern, these cells might have to contain many individual stitches, and combining multiple patterns in a single fabric requires the boundaries of each representative cell to be carefully and correctly matched up.…”

Figure 1: Stages of our knitted garment modeling system: (a) We begin our interactive modeling process with a polygonal mesh that specifies the global shape of the cloth model; (b) using this polygonal mesh we produce a high-resolution stitch mesh that serves as a canvas-like abstraction of the yarn model; (c) then, we specify the desired knitting pattern over the stitch mesh's surface. (d) Following the interactive modeling process, the model goes through offline relaxation, beginning with a mesh-based relaxation that moves the stitch mesh to the subdivision surface of the input model and slides its vertices over this surface based on the topology of the knitting pattern; finally, (e) we generate the yarn curves and (f) use a physically based relaxation process at the yarn level to compute the final realistic shape. AbstractRecent yarn-based simulation techniques permit realistic and efficient dynamic simulation of knitted clothing, but producing the required yarn-level models remains a challenge. The lack of practical modeling techniques significantly limits the diversity and complexity of knitted garments that can be simulated. We propose a new modeling technique that builds yarn-level models of complex knitted garments for virtual characters. We start with a polygonal model that represents the large-scale surface of the knitted cloth. Using this mesh as an input, our interactive modeling tool produces a finer mesh representing the layout of stitches in the garment, which we call the stitch mesh. By manipulating this mesh and assigning stitch types to its faces, the user can replicate a variety of complicated knitting patterns. The curve model representing the yarn is generated from the stitch mesh, then the final shape is computed by a yarn-level physical simulation that locally relaxes the yarn into realistic shape while preserving global shape of the garment and avoiding "yarn pull-through," thereby producing valid yarn geometry suitable for dynamic simulation. Using our system, we can efficiently create yarn-level models of knitted clothing with a rich variety of patterns that would be completely impractical to model using traditional techniques. We show a variety of example knitting patterns and full-scale garments produced using our system.

A knitted fabric must be pulled down during knitting in order to clear off the previously knitted loops from the needles when they are ascending. The conventional method is to place a weight, called the take-down weight, pulling the whole fabric. Alternatively, in the presser-foot system of knitting, instead of pulling the fabric from underneath, a wire pushes the last row of loops towards the previously formed loops. This wire extends only into the knitting zone; therefore, the fabric knitted by the presser-foot wire experiences no excessive tension during knitting, and is thus very close to the relaxed state.The 1 × 1 rib model described in Part I [1] of this series of papers is directly applied to presser-foot knitted 1 × 1 rib, interlock and half milano rib fabrics here in Part II. The aim of this study and the literature review on this subject were provided in Part I, and are not repeated here.Here, the model application of presser-foot knitted 1 × 1 rib wool fabrics is described below, in a similar way to the application of the model to conventionally knitted 1 × 1 rib wool fabrics given in Part I, completing the description of applications of the 1 × 1 rib model to 1 × 1 rib fabrics knitted in different knitting systems. The effect of fabric tightness on presser-foot 1 × 1 rib knitted fabrics is also discussed through the model and given in Appendix II.Furthermore, the direct application of the 1 × 1 rib model to an interlock fabric structure at a medium tightness is described. In addition, it is shown that the 1 × 1 rib fabric model given in Part I is also applicable to the rib course of half milano rib fabric. In this application two cases, namely dry relaxed and wash relaxed, are modeled. Kurbak's [2] plain knitted model is applied to the plain courses of half milano rib to complete the model of the whole structure. The models will be based on the experimentally obtained dimensional properties of the fabrics concerned; thus, a brief explanation of experimental findings are given as below. 1 ExperimentalPrevious experimental studies on the dimensional properties of 1 × 1 rib (conventionally knitted or presser-foot knitted) were described in Part I [1], therefore only brief explanations are given here. Large experimental works Abstract This paper deals with the creation of geometrical models for presser-foot knitted 1 × 1 rib, interlock and half milano rib knitted fabrics as direct applications of the 1 × 1 rib model given in Part I of this series of papers. The drawings of the models using 3DS-Max are shown and observed to be similar to the real fabrics through the photographs provided. The run-in ratio between the plain course and the rib course of half milano rib fabrics is emphasized as an important parameter for obtaining a stress-free structure, especially when using these fabrics as technical textiles.
