The shear behavior of fabrics is an important characteristic in fabrics whose end-use is for apparel purpose. The shear properties of the fabrics influence the draping, pliabiltiy and hand of fabrics. Moreover, the shearing behaviors of fabric have been applied in designing air ship, space suit and inflatable shelters. Therefore shear behavior plays very important role among the various mechanical properties of fabrics. The purpose of this paper is to analyze shear properties of polyester fabric in association with such fabric structural parameters as twist level, fineness, fabric density. Weave structure and processing factors. So far, correlation between shear properties and fabrics structural parameters and processing shrinkage with weave structure is examined. What is more. non-linear correlation between shear properties and fabric structural parameters is analyzed. Finally the regression analysis between processing shrinkage and shear properties and fabric structural parameters is carried on.

오애경 한국의류산업학회 2009 한국의류산업학회지 Vol.11 No.2

This study investigates the behavior of water vapor permeability of a layered system to find out a comfortable combination of a layered system for outdoor activities and examines the water vapor permeability of various types of outdoor clothing fabrics. The layered system includes the base layer such as sportswool and polyester/cotton fabrics, the middle layer such as single and double sided fleece fabrics, and the shell layer such as polyurethane-coated, PTFE-laminated and microfiber fabrics in this experiment. Results show that the layered system was applied, it was working together as a whole having some influence on each other layer, though every layer offered varying degree of water vapor permeability. Water vapor permeability of layered system exactly followed the same trend as the shell layer, which is all vapor permeable water repellent fabrics as a single layer. The rate of water vapor transfer through a layered system is mainly related to the type of vapor permeable water repellent fabrics used for the shell layer.

Adhesions are one of the most complications of surgery, and the leading cause of infertility, chronical pain and potentially intestinal obstruction. As the frequency of operation increases, prevention of adhesion formation has become a task to overcome in surgical research. A number of adjuvant have been investigated, including both pharmaceutical agents and physical barriers for adhesion prevention. Pharmaceutical agents and adhesion barrier have reduced adhesion formation in clinical practices to certain degrees, however, complete prevention of adhesions has yet to be overcome. In this review, the anti-adhesion agents were categorized into their uses and described of the properties of products commercially available. The purpose of this article is to review the current state of adhesion development and the effects of adhesion agents in prevention of adhesions.

The compressional property among fabric mechanical properties is of critical importance because it determines the practical quality and performance characteristics of textile materials and clothing. e.g. fabric hand and drape. fabric formability and shape formation in the appearance and shape retention of the clothing. In general the fabric compression behavior is influenced the weave structure, the number of yarn twist, the yarn linear density. the fabric density and the various processing parameters. In this study the effects of polyester fabric structural parameters, such as yarn linear density. yarn twist, fabric density. weave structure and the processing shrinkage on the compressional behavior of the fabrics have been investigated as a basic study on the hand characteristics on Hew Synthetic Fibre Fabrics.

The bending properties of the single yarns, such as the bending rigidity, the coercive couple, the hysteresis energy, and the residual curvature, are related with their constituent fibre diameters as well as the surface helix angle antral the linear density. The estimated and the experimental values of these properties are compared by varying the blend ratio of wool/polyester fibres. The validity of the specific bending rigidity was ascertained by adopting the value, which the experimental bending rigidity of the single yarn is divided by experimental yarn linear density. The bending rigidity of single blend yarns depends on the number of yam twist, the linear density and the blend ratio. The specific bending rigidity was decreased with increasing the number of yarn twist and blend ratio of polyester fibre. The coercive couple and the residual curvature, relating to intra-fibre friction in the yarn, were increased with blend ratio of polyester fibre. The coercive couple and the residual curvature of 100% polyester staple yarn were increased with the twist angle, and the maximum of these values were found to be increased as the blend ratios of wool/polyester fibres were increased.

Water Vapor Transfer of Outdoor Clothing System

오애경,안승국 한국섬유공학회 2019 한국섬유공학회지 Vol.56 No.4

Water vapor transfer through a fabric, and subsequently a layered clothing system, directly affects the human body’s thermal comfort. Clothing systems are essentially a way of layering clothes together to ensure comfort during outdoor activities. The aim of this study was to investigate the behavior of a clothing system’s water vapor transfer to determine a comfortable clothing system combination for outdoor activities. A water vapor transfer rate (WVTR) of 12 three-layer combinations of 100% wool and Coolmax fabrics as the base layer, two polyester fleece fabrics as the mid layer, and three waterproof breathable fabrics as the outer layer was tested. Our results show that when the clothing system was applied, it worked together as a whole with the layers having some noticeable influence on each other; it should be noted that every layer offered varying WVTR degrees. The WVTR of a clothing system is mainly related to the type of waterproof, breathable fabrics used for the outer layer. Therefore, a comparison of the WVTR of the outer layer to the clothing system shows that the exact same trend is followed. The WVTR of the clothing systems is significantly correlated with fabric treatments such as finishes, coatings, and film membranes that are added to the outer layer fabrics.
