In the paper, the tensile properties of cotton yarns are studied. A lot of data are gotten and analyzed. It indicates that the breaking strength of the yarns follows Weibull distribution. Then the effect of sample length on strength is analyzed using Weibull's statistics. The Weibull parameters are calculated through regression method. The breaking strength of the yarn at different sample length is predicted. Theoretical prediction conforms the experimental results very well.

The present paper investigates the effect of real seams on fabric bending using Peirce’s fabric cantilever. The effect of a plain seam with different seam allowances and seam positions are discussed on bending of the fabric cantilever. Vertical and horizontal seams are studied experimentally in terms of bending length. Simple structured fabrics of plain and twill weaves with various fiber contents such as cotton, silk, wool and polyester are used. Theoretical study of a vertical seam on bending properties of woven fabrics are exhibited. Experimental bending behavior of vertical seam is explained using the second moment of area ofthe fabric cross section.

Cloth has the nature of three-dimensional, flexible and non-rigid, some traditional methods based on 2D imaging and contact-type 3D surface measurement methods can not work for this kind of material. In this paper we present a study of digitalization of three dimensional cloth appearances based on stereo vision method. The 3D stereo system includes a set of mirror group (3D lens) and a digital camera with high resolution. Based on the camera geometry and stereo matching techniques, the depth map of cloth could be calculated so as to evaluate the 3D appearance of fabrics and related objects. The results show it is effective and workable to use this system to study the cloth/garment's 3D deformation or draping profile.

In this paper, the nonformaldehyde agent 1,2,3,4-butanetetracarboxylic acid was used for durable press finishing of silk fabric. To optimize the finishing, the effects of the amount of sodium hypophosphite, 1,2,3,4-butanetetracarboxylic acid and citric acid, curing temperature and curing time were examined. It was found that the wet wrinkle recovery angle had an obvious improvement from 179° to 273°, and that the finishing had a very small effect to the breaking strength.

Thermal-responsive shape-memory polyurethane consists of two phases, a thermally reversible phase for maintaining a transient shape and fixed phase structure for recovering the original shape. The use of shape memory polyurethane in clothing is a novel concept. The aim of this paper is to introduce the application of shape memory polyurethane to smart clothing, whose thermal insulation value could be change depending on the change of temperature of the external environment to give comfort regardless of weather change. Thus a review on the shape memory polyurethane is introduced: the mechanism of the shape memory polyurethane is described; the difference between ordinary polyurethane and shape memory polyurethane, the research on shape memory polyurethane and its potential application to smart garment are summarized; the work being carried out in the Hong Kong Polytechnic University are also introduced.

Seamless garment creation has attracted substantial research and is currently growing in its commercial applications. This paper reports a study which aims to invent an approach of integrating textile and fashion designs in seamless fashion creation. Based on the current industrial bi-axial weaving machine, a study was carried out to expand and invent weaving techniques with particular reference to double nterlacing toward a type of weaving seamless fashion (SWF) for developing a creative process and product of woven textiles and fashion. The method and theory of creating seamless woven fashion (SWF) were built upon certain hypotheses, experiments and analyses. Results show that by deploying advanced computer aided design systems, the production of seamless woven fashion (SWF) using multi-layer weaving techniques and a combination of stable and shape changeable fibers can be manufactured efficiently with a relatively simplified procedure that optimizes the design and manufacture process as opposed to the convention of fashion creation. It is envisaged that the results of this study will provide an alternative method of fashion creation, widen the creative and esthetical dimensions of textile and fashion design, and will enhance further research in these areas of integrated textile and fashion design systems.

The work represents an advance in understanding spider silks related to supercontraction which is clearly the water triggered shape recovery phenomenon. A structural model of spider silks is established, which can integrate a number of phenomena such as tunable mechanical properties, the origin, functions and ground state of supercontraction. The shape memory mechanism of protein fibers lays foundation for man-making and bio-mimicking spider silks using chemical approaches rather than genetic ones.

Permeability is a key aspect in fibre reinforced composite fabrication. Related problems include the formation of dry spots or voids within composites. These are difficult to solve during composite fabrication particularly with multi-layer woven preforms. To solve these problems, it is important to investigate the relationship between permeability and the microstructure of 3D Multilayer Woven Fabrics (MWFS). In this study, two-dimensional flow experiments with radial liquid injection were carried out to determine the permeability principal values. Based on the experimental results, a basic model for predicting the in-plane permeability of 3D Multilayer Woven Fabrics is established to calculate local permeability values of textiles with different stitch structures. Good agreement was found between the model prediction and the permeability measurements.

The automated defect detection of jacquard fabrics is intuitively appealing to the textile industry but as yet there has been little in-depth research in this field. In this paper, we introduce a defect detection method for use on jacquard fabrics that is based on multiple color-channel analysis. According to the number of color yarns employed, a number of color channels can be extracted from an arbitrary jacquard fabric. Images of each color channel are patterned. By first separating the color channel of an input test fabric image, and then eliminating noise and applying a pattern extraction process, it is possible to produce a set of channel patterns. To characterize each defined defect, we introduce a pattern comparison method which makes use of Fourier transform and frequency spectrum analysis. In experiments, this method efficiently and precisely detected defects in test fabrics and provided relevant information about defects such as the defect category and which color yarns are involved in the defect.

Seamless woven fashion is approachable via the Jacquard technology. With the rapid development of weaving technology and materials, an attempt is being made to expand and invent the technical and creative scopes of 3D Seamless Woven Fashion (SWF). The thrusts of the study are to establish complete design principles for advancing creation of SWF. In this study, three technical elements of weaving design have been identified in the course of SWF creation, i.e. elastic yarn, integrated structure, and integrated pattern. Past experiments so far suggested that it is possible to obtain different shrinkages as well as seamless woven textiles with varied richness and novel textures by adjusting the tightness of basic weaves. Moreover, three forms of layered structures, i.e., F (Flat), 3D-MnL (3-dimensional form on mono-layer) and 3D-MtL (3-dimensional appearance between multi-layers) were incorporated on different parts of a garment against specific requirements and/or performance. The construction of 3D shapes of SWF contributes to variety of fashions as well as woven textiles.
