The theory presented in this paper differs from previous ones in that no arbitrary loop shape is assumed. Rather a strophoid curve, that is similar to knitted fabric Loop shape, has been assumed as the basic mathematical function. Additionally, the theory is improved by adapting buckled elastic rod theory, leading to a new equation from a certain mathematical curve. This loop model is assumed to be two- dimensional initially, but is applicable to three-dimensional analysis as well. The geometry of the fabric structure is obtained from these models. The results show good agreement between the theoretical and experimental suggestions reported by other scholars.read more

A New Aspect of Geometrical and Physical Principles Applicable to the Estimation of Textile Structures: An Ideal Model for the Plain-knitted Loop
TL;DR: In this paper, the classical curves that are similar to the knitted-fabric loop shape are considered as a function of an ideal model for a plain-knitted structure, and the assumed function is then improved by adopting a buckled-elastic-rod theory, leading to a new equation as the ideal loop configuration.

Ali A. A. Jeddi,A. Zareian +1 more
TL;DR: Mohammadi and Jeddi as mentioned in this paper developed the ideal model knitted loop (Jeddi et al., 12, 39−44, 1999, Semnani et al. 2003) for the fully relaxed 1 × 1 rib structure, which is based on the classic curve of Strophoid equation as the loop shape of face and back loops and improved by adopting an elastica configuration.

An explanation of warp knitted fabric deformation under uni-axial tension by a novel index as shape ratio
TL;DR: In this paper, a geometrical index named shape ratio was defined to quantify the deformation of warp-knitted fabrics in order to use instead of Poisson's ratio, which is obtained by division of the variation of squared perimeter to the area of a printed square on the fabric under uniaxial tension.

A novel technique for modeling friction behavior in knitted fabric simulation
Vajiha Mozafary,Pedram Payvandy +1 more
TL;DR: In this paper, the authors proposed a novel technique for modeling fabric-object friction force in knitted fabric simulation based on the mass spring model, unlike other studies, the distribution of friction coefficient over the fabric surface is not uniform and depends on the fabric structure.
