Angle-interlock woven fabric offers an option for making female body armor as it can form integrally the required dome shapes because of its extraordinary moldability and satisfactory ballistic performance. A mathematical model is created to determine the pattern geometry for the front panel of female body armor, and the front panel can be quickly created using this mathematical model. However, the body armor is multi-layer, which indicates that the relationship between the thickness of the fabric and the pattern block projection for different layers of fabric needs to be investigated, in order to create the whole panel, to improve this novel approach for making seamless female body armor with satisfactory ballistic performance.

The Relationship

Moisture management is defined as the controlled movement of water vapour and liquid water (perspiration) from the surface of the skin to the atmosphere through the fabric. The ability of moisture transport is a very important feature of textile materials from the point of view of the physiological comfort of usage clothing made of these materials. Among the different textile materials (woven, knitted and nonwoven), seersucker woven fabric is considered as having good comfort-related properties. The fabrics are characterised by the occurrence of puckered and flat strips in the warp direction. The puckered effect generates air spaces between the body and the fabric, keeping the wearer cool in hot conditions as the puckered area holds the fabric away from the skin during usage. In the work presented, seersucker woven fabrics of different patterns of the puckered strips were investigated. The aim of the work was to analyse the relationship between the structure of seersucker fabrics and their moisture management properties. Measurement of the moisture transport properties of seersucker woven fabrics was made using a Moisture Management Tester M290, produced by SDL Atlas. Investigations performed showed that the properties of seersucker woven fabrics characterising their ability to transfer liquid moisture are different depending on the variant of the repeat of puckered strips.

In addition to fiber properties, the fabric structure plays an important role in determining ballistic performance of composite body armor textile. Textile structures used in ballistic protection are woven fabrics, unidirectional (UD) fabric structures, and nonwoven fabrics. In this article, an analytical model based on wave propagation and energy balance between the projectile and the target is developed to analyze hybrid fabric panels for ballistic protection. The hybrid panel consists of two types of structure: woven fabrics as the front layers and UD material as the rear layers. The model considers different cross sections of surface of the target in the woven and UD fabric of the hybrid panel. Also the model takes into account possible shear failure by using shear strength together with maximum tensile strain as the failure criteria. Reflections of deformation waves at interface between the layers and also the crimp of the yarn are modeled in the woven part of the hybrid panel. The results show greater efficiency of woven fibers in front layers (more shear resistance) and UD yarns in the rear layers (more tensile resistance), leading to better ballistic performance. Also modeling the yarn crimp results in more trauma at the backface of the panel producing data closer to the experimental results. It was found that there is an optimum ratio of woven to UD materials in the hybrid ballistic panel.

The Relationship

This chapter examines the relationship between the body, globalization, and the media. It discusses how the female body is subjected to being “played” in the global media and what that reveals of gender and minority–majority relationships and of global aims and fears. The cases presented in this chapter serve as samples of “sexy violence” imagery that cannot be thoroughly explained by theories of objectification, liberation, or commodification of women but, rather, are considered in reference to the socially constitutive role of globalization. Although the female body may function to discursively dissolve, enforce, or alleviate conflicts embedded in the processes and discourses of globalization, the preoccupation with “sexy violence” imagery in the global media does not necessarily offer a solution to global concerns but, rather, plays out the fears, aims, and anxieties about globalization through violence and aggression.

The Relationship

A range of intricate finished seamless shaped garments have been developed with the aim to fit predetermined sizes. The shape is created by using woven tubular fabrics with differential shrinkage in the same garment. The differential shrinkage is obtained by altering the fabric construction parameters at strategic locations along the length of the garment. The construction arameters include different weaves (plain, 2/2 basket, 1/3 twill, 2/2 twill, and crowfoot), weft densities, weft yarn counts, and weft yarns with different shrinkages (cotton, cotton that contains spandex, and cotton/polyester yarns). The weft yarn tension is used as an additional parameter to influence fabric shrinkage. A total of thirty-three woven fabrics are formed to establish the relationship between the construction parameters, weft tension, and shrinkage of the finished woven fabric. The relationship is used to produce a range of intricate garments with inherent shapes and predetermined sizes.

The Relationship

To evaluate the ability of woven fabrics to drape in a more accurate way, a three-dimensional point cloud of a draped woven fabric was captured via an in-house drape-scanner. A new indicator, total drape angle (TDA), was proposed based on the three-dimensional fabric drape to characterize the ability of a woven fabric to drape. The relationship between TDA and the drape coefficient (DC) was analyzed to validate the performance of TDA. The result indicated that TDA is more stable and representative than the traditional DC in characterizing the ability of a woven fabric to drape. In addition, the drape angle distribution function (DADF) of the triangular mesh was employed to describe fabric drape, as well as to bridge the gap between drape configuration and the warp bending rigidity of woven fabric. The results showed that the correlation coefficient between the real warp bending rigidity value and what was predicted warp based on DADF and fabric weight was 0.952.

Iridology is the study of the iris of the eye to detect the conditions of the body and its organs, genetic strengths and weaknesses, etc. Although iridology is not widely used as a scientific tool for healthcare professionals to get to the source of people's health conditions, it has been used as a supplementary source to help the diagnosis of medical conditions by noting irregularities of the pigmentation in the iris among some Korean Oriental medical doctors. Angiotensin converting enzyme (ACE) gene polymorphism is one of the most well studied genetic markers of vascular disease. We investigated the relationship between iridological constitution and ACE polymorphism in hypertensives. We classified 87 hypertensives and 79 controls according to iris constitution and determined the ACE genotype of each individual. DD genotype was more prevalent in patients with a neurogenic constitution than in controls. This finding supports the hypothesis that D allele is a candidate gene for hypertension and demonstrates the association among ACE genotype, Korean hypertensives and iris constitution.

AbstractElectro-conductive (EC) yarns can be woven into a hybrid fabric to enable electrical current to flow through the fabric from one component A to another component B. These hybrid fabrics form the bases of woven e-textiles. However, at the crossing point of an EC yarn in warp and in weft direction, there is a contact resistance and thus generation of heat may occur in this area. Both phenomena are inseparable: if the contact resistance in the EC contact increases, the generated heat will increase as well. Predicting this electrical and thermal behavior of EC contacts in hybrid woven fabrics with stainless steel yarns is possible with a mathematical model based on the behavior of a metal oxide varistor (MOV). This paper will discuss in detail how this can be achieved.

The Relationship

During the nineteenth century, Swedish gymnastics became one of the main models of physical education in the Western world. The purpose of this article is to explore how Swedish gymnastics was adjusted to the female body and mind in the mid-nineteenth century. Using handbooks published by the Swedish educationalist Anton Santesson as an empirical starting point, this article shows how the relationship between gender and gymnastics was complicated and exhibited significant discrepancies. In part, Swedish gymnastics was marked by a one-sex model of gender differences, which meant that gymnastics was perceived as a method for catering to the deficiencies and weaknesses of the feminine nature, in an attempt to make girls and young women more similar to boys. Swedish gymnastics had, nevertheless, vital elements of a two-sex model, according to which gymnastics was supposed to realise the true feminine nature of girls. Following this line of thought, Santesson claimed that, since gymnastics merely followed the laws of the body, it could not make girls more like boys. Santesson’s vision of gymnastics also included disciplinary mechanisms, such as the partitioning of space, which were gender neutral. Apart from presenting insights into the ambiguous and contradictory notions of gender in Swedish girls’ gymnastics, this article thus also raises questions regarding whether other models of physical education were marked by similar discrepancies during the nineteenth century.
