In present era of modernization in the textile field, we are going through new developments of technology. To ensure our security and safety from the hazards, we need to development the technology that should be reason for our protection. With regard to textiles, a mosquito repellent textile is one such textile product. It protects the human beings from the bite of mosquitoes and thereby promising safety from the diseases like malaria, dengue etc [1]. This abstract presents results of an investigation into mosquito finishing of cotton knitted fabric to improve water repellency. To impart this character in textiles we used commercial mosquito repellent finish that adheres with fabric by commercial binder. In next route of process we replaced commercial binder with natural binder chitosan. The main objective of this study was to investigate the possibility of using Chitosan as a binding agent for commercial repellent finish in order to increase the mosquito repellency and durability of cotton textiles. In result higher repellency was achieved when using chitosan as a binding agent. Additionally, resulted the increase in tensile strength of cotton fabric, thus increase in wash durability.

Green approach refers to a use of natural and renewable source of energy replacing or reducing environmentally unfriendly materials like steel. The present study discusses about the importance of coconut fiber as an ad-mixture for roofing, its advantages and scope in future. As we all know, steel is used as a reinforcing material for holding the concrete and making it crack resistant. But, due to its number of demerits, which includes its high cost, nonrecyclability,corrosiveness, high weight and low strength ratio, with time, a number of innovations have taken place.
‘‘Textile Composites’’ entertains the use of coconut fiber, which can also be used as a strengthening material for roofing apart from steel. Two inherently different materials out of which one belongs to textiles are mixed to form a new material, different to both but better in properties are called as textile composites.

Use of coconut fiber (Coir) should be valued over Steel for the following reasons like low cost, recyclability, noncorrosiveness, low thermal conductivity (natural cooling), high strength and low weight ratio. In earthquake prone areas where frequent damage to infrastructure takes place, the use of Natural fibers such as Coir instead of steel will prove advantageous. In this paper, we will be focusing on the above-mentioned points in detail and our research work will prove that use of coconut fiber in roofing proved to be very lucrative.

Warping is a low yield operation owing to the time needed for creeling; the creels are the frames on which the cones which feed the warper are pinned. The number of cones depends on the type of fabric to be produced. The yarns are wound side by side and parallel one another on the beam, Also keep in mind that the number of yarns per beam is in the hundreds or thousands and that there must, at least, be one supply package for each of these yarns, if possible with the same tension, so the cone position and their accessibility are two important factors for the operator.
This paper reports a study on producing 27 different material yarn samples by an indirect warping machine (Benninger, Ben-Ergotronic, Switzerland) used in part 1 with (V) shaped creel, the samples of the yarn manufactured from three different material (Cotton, Spun polyester and Polyacrylic) In addition, three different yarn count 30/2, 16/2, 8/2 Ne for cotton , spun polyester and 40/2, 28/2, 14/2 Nm for Polyacrylic yarns under the same yarn pressure, with three different distances between warping drum and cone position on warping creel 4 m, 8 m and 12 m with the same warping speed were tests measuring tensile strength and elongation.
The results of measurements of warp yarn under study for tensile strength and elongation for deferent warpmaterials and position of cone installation on warping creel for the properties of the yarn through laboratoryexperiments and make classification of preference for operating under different warping yarn conditions

The purpose of this research was to develop a generalized adaptive 3D body model the posture of which could
be adapted to different positions in order to perform a virtual prototyping of garments for people with limited body abilities. The digital data of a tested person’s body was acquired using the GOM Atos scanning system. Careful surface reconstruction was performed in order to provide an adequate mesh for further posture adaptation. The experimental part of this article presents the usages of a variety of graphic programs in order to provide an adaptive 3D body model through kinematic skeleton construction. The mesh-deformation during posture adaptation was improved using advanced tools of applied software packages. The usefulness of the gained 3D body model was determined by calculating the differences between the real and digital 3D body model measurements.

Polymer nanocomposites have attracted great interest during current years. Cellulose micro-fibrils may be function as biodegradable Nano fibrils in high performance composites. The production of Nano-scale cellulose fibers and their application in composite materials has gained increasing attention due to their high strength and stiffness combined with low weight, biodegradability and renewability. Adding small amounts of cellulose-based fillers to thermoplastic matrix polymers usually enhances the mechanical properties. However, the development of fully biodegradable nanocomposites is still a challenging area. Many researchers investigated production of micro cellulose microfibers through various methods. The most important and widely used methods for cellulose Nano fibers isolation are Chemical method (CM), Mechanical methods, Physical methods, Using microwave, Biological and High-pressure homogenizer. CM process is easier than milling process (MM) by which material is reduced from a large size to a smaller size ‘top-down’. In this work, a motor driven mechanical rotary microtome sheering device was used to produce microfibrillated cellulose (MFC) particles from different types of cotton fibers and cotton waste, as well as flax. The morphological properties of the cellulose particles were investigated by means of scanning electron microscopy. Final length distribution of cellulose particles was determined. It was found that the maximum number of fibers was observed in the range from 0.5 to 2 microns with average aspect ratio 1.6. Depending on the source of the fibers, the particles with a diameter of 20 – 500 nm were observed.

Surgical gowns are supposed to act as a pathogen barrier and provide physiological comfort for surgeons. This study was concerned with both of the aforementioned aspects. For this purpose surgical gowns used in public and private hospitals in Egypt were surveyed and one was chosen as it represented the most common type of gowns used in those medical facilities. The antimicrobial properties as well as the physiological comfort represented by its moisture management capacity were tested to evaluate its functional performance with regard to those specific areas. The results revealed that as far as acting as a pathogen barrier, according to Parallel Streak Method, the tested surgical gown proved to have an efficient inhibition zone because of the antimicrobial treated PET fibres and to the very poor overall moisture transfer capacity as a fabric (OMMC=0). As for the physiological comfort the opposite proved to be true as the very poor moisture management capacity (OMMC=0) meant diminished physiological comfort which was proven to affect surgeon’s performance in previous studies.

Fashion industry is a multimillion industry. Garment industry is divided into the production of clothes and fashion products. It is focused on achieving optimal results concerning supplies, preparation, production and distribution of fashion products. It is characterized by development of fashion trends, brands, development of distributive network and stores and optimization of logistics from production to retail stores. Technical-technological development in the last forty years enabled garment industry to implement new methods and procedures and increase productivity while using new textiles and knitting. On that way the industry keeps up with more complex wishes of consumers, demands and fashion trends in the world. The most important tone concerning the rate of growth, design, fashion, utilization and size of assortment is given by centers of large consumption, i.e. the richest countries.

Nonwoven is a textile product which is engineered in a very sophisticated way with the aid of modern technologies. Probably, these modern technologies [1] are one of most important force which brought nonwovens up to the age of technical textiles. The term ‘Nonwoven’ came in existence more than half a century ago and at that time it was regarded as the low grade cheap substitute for traditional textiles. In its early stage it was manufactured from dry laid carded webs with the help of modified textile processing machines. Europe is the place where nonwoven originated, grown and matured. Now, the whole world together is making it more and more famous and useful. EDANA (The European Disposables and Nonwovens Association) and INDA (North America’s Association of the Nonwoven Fabrics Industry) has defined nonwoven [2] very well. It can be better understood as ‘a manufactured sheet, web or batt of directionally or randomly oriented fibres, bonded by friction, and/or cohesion and/or adhesion, 50% by weight of which contains fibre having length to diameter ratio more than 300’. So, it is a textile product in sheet form, having equivalent (or better properties for some specific applications) properties as traditional fabric, manufactured directly from fibres.

Organic compounds possessing two cationic or anionic groups separated by relatively large distances have been named ‘bolaform electrolytes (bolytes)’ [1,2]. The word ‘bola’ means a long cord with heavy balls at each end used by the gauchos in the Argentinian pampa to capture cattle. When the distances, generally the alkyl chains, are sufficiently long, the bolaform electrolytes become surface-active compounds. Such surface-active compounds are named ‘bolaform amphiphiles (bola-amphiphiles)’. Various physical properties of the bolaform electrolytes or amphiphiles have been extensively studied. The surface activity, solubilization properties and micelle formation for some bolaform electrolytes have been discussed in detail. The application of the bolaform amphiphiles to monolayer lipid membranes has also been reported. Furthermore, a study on the micelles or vesicles formed from crown ether-based bolaform amphiphiles has been reported.
