26—the “handle” of cloth as a measurable quantity

Abstract: In judging the feel or “handle” of a material, use is made of such sensations as stiffness or limpness, hardness or softness, and roughness or smoothness. It is desirable to devise physical tests that analyse and reflect the sensations felt and assign numerical values to the measurements. The present paper describes tests that reflect the first groups of sensations, namely, stiffness and hardness, whilst the sensation that is experienced in stroking a material, obviously connected with frictional properties, will be dealt with in another paper. An instrument is described on which it is possible to measure the angle through which a specimen of cloth droops when a definite length is held out over an edge. By means of a mathematical formula that is fully developed in an appendix to the paper this angle is converted into a term called the bending length of the material. This quantity may be defined as the length of fabric that will bend under its own weight to a definite extent. It is strictly a meas...

Fabric Performance in Clothing and Clothing Manufacture

Abstract: After the performance of clothing fabric in use has been satisfied to some extent, consumers seek better-quality, that is, more comfortable, fabrics. Fabric performance in relation to ‘better fitting to the human body’ is an essential requirement of clothing materials. From the mechanical-comfort viewpoint, textile producers and consumers have evaluated this kind of fabric performance by a subjective method, called handle judgement. For the engineering design of the fabric performance with regard to fabric handle, this subjective method must be analysed to explain what the fabric handle is and how it is judged. In this paper, recent developments in the analysis and standardization of fabric handle, mainly used by experts in textile mills, are first introduced, and then the development of the objective-evaluation system of fabric handle based on fundamental fabric mechanical properties is described. This is a type of expert system, and the translation software from the fabric mechanical data to handle has ...

Structure and Mechanics of Woven Fabrics

Abstract: This chapter discusses and reviews the fundamental science and technology behind fabric structure and mechanics. The chapter introduces the extent of knowledge regarding fabric deformations, such as tensile, bending and shearing, and a new kind of testing method based on image analysis to characterize fabric mechanical behavior. A general review of computer simulation techniques for woven fabrics and garments is also presented.

Finite-element modeling and control of flexible fabric parts

Abstract: Software based on nonlinear shell theory can simulate 3D motions related to real fabric-manufacturing processes. This simulation capability advances the technologies necessary for automating the textile and apparel industries.
