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.

This paper presents the continuation of research on shielding efficiency (SE) of electromagnetic radiation (EMR) by woven fabric made of cotton (warps and wefts) and a hybrid yarn (wefts). This hybrid yarn was made of stainless steel yarn by Bekinox wrapped with an enamelled copper wire from Synflex Elektro GmbH, Germany. The pitch of copper coil on a hybrid yarn equals 3 mm. The wefts were introduced into the fabric in the following order: 1 hybrid yarn, 1 cotton yarn, 1 hybrid yarn, 1 cotton yarn, etc. The construction of this specific fabric was proven to be the most efficient in terms of the hybrid weft construction and the fabric construction to shield EMR among other previously tested fabrics with different weft configuration. The current study proposes to verify the effect of the number of layers of the fabrics and their mutual configuration on the final SE of the multilayered set. Some of the most interesting findings of this study are that increasing the number of layers placed on top of one another with an offset angle of 0° to more than two does not provide a higher SE; however, using three such layers provides an SE of 56 dB, which is over two times higher than that provided by a single layer. Increasing the number of layers of fabric aligned at an angle of 45° provides a higher SE only for a frequency of 30 MHz.

Joining textile layers to a preform using patches is of utter importance in regards to producing structural elements made of fibre-reinforced materials with complex geometry, and repairing fibre-reinforced composites in an efficient and safe manner. Material-efficient and load-specific design and integration of the patch are essential in relation to the performance of the joint as well as the strengthening of the composite structure after a damaging event. Hence, in this study, the stress–strain behaviour of carbon-fibre-reinforced epoxy-composites, which are joined by a patch designed as double-lap joint, will be investigated. It will be shown that the woven fabric morphology (surface structure) and the woven fabric construction (weave pattern) of the join partners exert a noticeable influence on the stability of the patched composite samples. The use of leno non-crimp fabrics as patch structures, which provide an increased joint surface in comparison to the likewise examined twill fabrics, enables a growth in joint strength, provided that the dimensions of the patch remain the same.

Abstract The article is focused on testing of selected properties of linear and planar textiles from modified cotton yarns. In this article, the influence of woven fabric construction on wettability and possibilities of detection of moisture in the woven fabric is analyzed. Improving the physiological and hygienic properties for woven fabrics can be achieved with a specially designed textile structure in combination with a permanent surface finish of sub-set of yarns. Inserting of hydrophilic and hydrophobic set of threads in the woven structure makes possible controlled water transport. Controlled transport of water ensures good clothing comfort. Using such woven fabric, accumulation of water on the skin does not occur during the process of thermoregulation of the human body. The properties and behavior of the designed fabric will be determined by surface finishing of the warp and weft yarns (sub-set of yarns), which are supporting elements of the fabric.

Sulphonated jute fibres were blended with cotton at three different ratios, e g. 50:50, 60:40 and 70:30 for production of fine yarn and comparatively better ratio have been investigated. The plain woven fabric were prepared by sulphonated jute-cotton yarn. The set of warp and weft blended yarns was done on the one up and one down principle. The physico-mechanical properties of blended yarn and fabrics were studied and compared with that of jute yarn, cotton yarn and fabric. Key words: Sulphonated jute fibre, jute-cotton blend, mechanical properties, tensile strength and fabric construction. Bangladesh J. Sci. Ind. Res. 42(3), 281-286, 2007
