“…We regard the single fiber as a random fractal set, a kind of statistically self-similar object [3,4], So we used modified random Koch curves generated according to L-system theory to simulate the morphology of crimped fibers.

In this paper a fractal method was applied to understand the crimped morphology of a fiber. Firstly, image processing and box counting method were used to analyze the fractal characteristic and the dimensions of the fibers such as polyester, nylon, wool, flax, and so on, and then, the crimped morphologies of the fiber were simulated by using modified random fractal curves. The morphologies of the random fractal curves are very similar to those of tension free textile fibers.

We investigate the effects of the cross-sectional structure of a polyester-type polyurethane (~u)/polyvinylchloride (pvc) blend dope-coated nylon fabric on moisture permeability. The waterproof coating is applied 6y a one-sided wet-coagulation process. The blending of hydrophobic pvc to hydrophilic PU forms a three-layered crosssectional structure-a pvc-rich ~nicronetwork, a porous PU-rich layer, and the nylon fabric. As the blend ratio of pvc to PU increases, the moisture permeability (hip) and dew condensation (DC) of the coated fabrics improve. Compared to the PU homopolymer, the hip value of a PU/PVC blend in a weight ratio of 4:l increases 1.18 times to 492 g/m2.h (JIS A-1 method) and 1.16 times to 815 g/m2.h (JIS B-1 method), but the DC value decreases one-fourth to 4.60 g/m2. h. This gradient three-layered crosssectional structure contributes to vapor transport properties.

Objective and subjective methods for testing of fibers, yarns, and conventional fabrics are presented in this article. A brief discussion of testing methods for geotextiles and geomembranes is also given. Methods reviewed are mainly from ASTM and American Association of Textile Chemists and Colorists (AATCC) standards. Specific properties discussed are, for fibers, length, crimp, transverse dimensions, density, cross‐sectional shape, shrinkage, friction, optical, tensile and elastic properties, moisture absorption, and electrostatic and thermal properties; for yarn, size and number, twist, strength, evenness, friction and texture; and for conventional fabrics, construction, thickness, air permeability, strength and elongation, snag, pilling and abrasion resistance, shrinkage, thermal and moisture transmission, color and wash fastness, flammability, hand, drape, wrinkle resistance, luster, and comfort. Test methods for geotextiles and geomembranes include those for filtration and clogging, permeability, permittivity and pore size, tensile properties, degradation by ultraviolet light and temperature, abrasion, friction, and construction parameters, including mass and thickness. Where appropriate brief discussions of fiber, yarn, and fabric properties are included as they relate to the testing procedures. Testing equipment available for making particular measurements has also been given in many instances.
