Smart textiles are prominent in the textile industry, with applications in various technical areas such as medicine, architecture, sports, and esthetic purposes, among others. Within this concept, optical fibers are classified as passive smart textiles and are highly attractive for clothing lighting and monitoring physiological parameters. This study aimed to present methods for inserting polymeric optical fibers into weft single knitted fabrics and verifying the loss of luminosity in them, analyzing the technical feasibility of developing e-textiles to be applied in monitoring. For such, weft knitted fabrics were produced by altering the optical fiber insertion methodology, defined as inlay insertion and insertion in the course direction, each subdivided into different methods. Light transmission was verified using a laser pen connected to the optical fiber. Images were captured and analyzed using LILP software to verify and quantify the loss of luminosity in each insertion method. Light transmission microscopy was performed to evaluate the surface of the polymeric optical fiber used. For the insertion techniques performed, inlay and by course direction, the result obtained for signal transmission was satisfactory;however, the inlay insertion methods presented lower light emission but lower luminosity loss than the insertion by course direction. This result is very interesting because it enables the development of weft knitted fabrics from the use of optical fibers for application in various types of monitoring. © 2024, The Authors.

textiles for military clothing face a complex set of challenges. They must provide protection, durability and comfort in a wide range of hostile environments. The general requirements of military textiles include damage resistance, comfort, sweat management, cold-weather conditions and the integration of high-tech materials into uniforms. This paper discusses the main concepts regarding the application of textiles in military uses, where the surrounding environments such as desert, jungle or extremely cold areas as well as the nature of the situations involved pose a threat to the soldier's safety. Therefore, the improvement and development of fibrous materials, textile structures and finishing processes can bring new perspectives for saving lives. © 2019 Trans Tech Publications Ltd, Switzerland.

In this work, a weft-knitted fabric produced from 100% meta-aramid (MA) fibre was functionalized by using polyelectrolyte, Poly (diallyldimethylammonium chloride) (PDDA), in order to modify its surface for dyeing with an uncommon dye class for MA fibres. Contact angle, dye solution drop adsorption, Scanning Electron Microscopy (SEM), reflectance spectrophotometry, washing and rubbing fastness tests were performed to study the effects caused by the interaction between PDDA and MA fabric. Good results of dyebath exhaustion with excellent values of colour strength were obtained for the samples previously treated with PDDA. These results showed the possibility of obtaining distinct and deep colours besides generating a lower energetic cost using shorter time and lower dyeing temperature as compared to those normally used in the MA dyeing process. © 2019 Trans Tech Publications Ltd, Switzerland.
