The main aim of this article is to collect the scattered knowledge of Cosmetotextiles and present it to the world scientific community for scrutiny. Various aspects of Cosmetotextiles are compiled systematically and oriented towards product development. The technology of Cosmetotextiles is at the neonatal stage. The joint efforts of textile technologists, biochemists, cosmetic experts and medicos can achieve challenging targets in the field of Cosmetotextiles. Various derivatives of metals, plants and animals are used in pure and derivative form to generate cosmetic functionality in textiles. Various routes for the incorporation of cosmetic potentail in textiles are available, of which microencapsulation and the use of cyclodextrin as cage material are the most popular. The content of moisture on skin surface is a key parameter in maintaining skin elasticity and glowing potential. The characterization of Cosmetotextiles is a difficult task, but the Europeans have taken the lead by classifying and standardising the testing of the cosmetic effects of cosmetotextiles.

The maximum weavability limit is predicted by extending Peirce's geometrical model for non-plain weaves for circular and racetrack cross-sections by soft computing. This information is helpful to weavers in that attempts to weave impossible constructions can be avoided, thus saving time and money. It also helps in anticipating difficulties in weaving and in taking the necessary steps in warp preparation. The relationship between the cover factors in the warp and weft directions is demonstrated for circular and racetrack cross-sections for plain, twill, basket and satin weave. Non-plain weave fabric affords further flexibility for increasing fabric mass and fabric cover. As such, they enlarge the scope of the fabric designer.

An attempt has been made to optimise the engineering attributes of a plain weave fabric according to certain requirements. A simplified algorithm was used to solve fabric geometrical model equations, and relationships were obtained between useful fabric parameters such as thread spacing and crimp, fabric cover and crimp, warp and weft cover. Such relationships help in guiding the direction for moderating fabric parameters. The full potential of the Peirce fabric geometrical model for plain weave has been exploited by soft computing. The interrelationships between different fabric parameters for jammed structures, non-jammed structures and special cases in which the cross-threads are straight were obtained using a suitable algorithm. It is hoped that the fabric designer will benefit from the flexibility in choosing fabric parameters for achieving any end use with the desired fabric properties.

Few can dispute the tremendous values of linen, which is one of nature's greatest treasures. Linen is a longer-staple category, and as such the fibre is spun on a long-fibre spinning system. Due to the coarseness and stiffness of the fibre, linen fabrics are subjected to a strong bleaching action to reduce the stiffness of the fabric. Linen is also blended with other compatible natural and manmade fibres to achieve various structural and functional properties, and also to reduce costs. Fabrics produced from 100% linen and their blends with cotton and viscose have been studied for handle and comfort properties. Linen fabrics produce excellent aesthetic and drape properties. Linen fabrics are found to be tougher than cotton and other blends. However, linen offers the highest tensile resilience and the lowest friction coefficient under low stress-loading conditions. Linen fabric produces superior primary hand with respect to Fukurami and Shari. The total hand value (THV) of processed linen fabric is higher than that of cotton fabric as a summer wear. The blending of viscose and cotton improves the hand value of linen fabric.

The optimum-size add-on for corespun Dref yarns and 100% cotton Dref yarns was studied, and was found to be approximately 15%. A rich size recipe consisting of acrylic at high add-on further improves the weavability, although it fails to bring the weaving potential to a par with that of ring- and rotor-yarns sized with normal modified starch at low add-on.
