Technical Textiles and Recent Developments
Published in Asis Patnaik, Sweta Patnaik, Fibres to Smart Textiles, 2019
As per the widely used definition, ‘textile materials and products manufactured primarily for their technical and performance properties rather than their aesthetic or decorative characteristics is known as technical textiles’ (Textile Institute 2014). As per another definition, ‘Technical textile materials are designed to have high level of physical, mechanical, thermal and/or chemical properties for use in specific applications within industrial sectors such as earthworks, construction, civil engineering, transport, defense, medical and healthcare’ (Definitions of Technical Textiles 2016). Sometimes other terms like industrial textiles, functional textiles, engineered textiles, performance textiles, etc. can be used instead of technical textiles (Horrocks and Anand 2000, 2016).
Specialty Fabric Structures

Shaped weaving is also the interlacement of warp and weft yarns, but the final product is a shaped fabric. Shaped fabrics may be of single layer or more than two layers [14]. Single-layer fabrics have a shape of any type such as a corner or V-shaped, and multilayer fabrics may be of T-shaped or H-shaped, tetrahedral shape, seamless woven fashion, or any hole in the fabric. Shaped fabrics can be produced on conventional dobby looms with no extra atomization in the loom and on electronic jacquard loom and also on 3D loom, but this is not commonly available. As woven fabrics have excellent properties such as stiffness, strength, and dimensional stability, they are used in technical textiles. Pile yarns are added to provide sufficient stability and compression. Spacer fabrics are used in air and space industries, tires of vehicles, and automotive and transportation industries to achieve good tensile strength, compression, and stiffness; the material properties and process properties are optically combined [15].
Digital Printing
Published in Asim Kumar Roy Choudhury, Principles of Textile Printing, 2023
In the production of technical textiles, the main focus is on functional properties. For textile companies, 3D printing processes open up possibilities that cannot be realized with conventional processes. Elements such as plug-in connections can be applied directly to textile surfaces using 3D printing. In this way, textiles are created that integrate functionalities right from the start.
Auxetic fibrous materials and structures in medical engineering – a review
Published in The Journal of The Textile Institute, 2023
Auxetic materials are used in a broad variety of applications, from vehicles to medicinal medication delivery systems. Auxetics, as previously mentioned, may be employed in a variety of settings in the area of biomedical engineering. Although, since much of the research has mainly concentrated on lab-scale procedures and processes for the manufacturing of auxetic textiles, a technological update is necessary for the creation of auxetic materials, particularly fibrous materials for industrial production. Furthermore, since the domain of auxetic fibrous materials modeling is untested, research in this area should be done for the optimization of the NPR according to a certain application before sample manufacturing. Auxetic textile materials, without a doubt, have a lot of potentials to be categorized as smart and intelligent textiles and used in medical engineering applications. As a sophisticated material, technical textiles continue to enable new generations of medical technologies such as wound care and closure, electro-stimulation, regenerative medicine, and smart wearables. For years to come, increasing expectations from patients and practitioners will undoubtedly push innovation and new technologies in the area of biomedical engineering using technical textiles.

The versatility of textiles allows for a wide range of applications in the medical field, protective clothing, lightweight construction, or filtration applications. Technical textiles are fabrics designed with the explicit purpose of application performance, for example, stiffness, strength, chemical or mechanical resistance, fire resistance, absorbency, or permeability. In principle, there are two kinds of technical textiles, woven and nonwoven fabrics. In contrast to the structured networks of wovens, nonwovens are composed of disordered fiber networks, consolidated by chemical, thermal, or mechanical bonding (Jubera et al., 2014). These materials commonly display a lower stiffness and strength than woven fabrics while also being able to endure higher deformation strains and absorb more deformation energy (Ridruejo et al., 2011). Polypropylene low-density nonwovens serve as filter media in automotive applications where high filtration efficiencies are required. These fibrous and porous filter media are made of fibers bonded by partially melted fiber material as bond points, allowing for high permeability and simultaneously high specific surfaces. Figure 1 depicts an example of such a filter media used for cabin air filtration.

The technical textiles sector is characterized by the duality of extension and diversification of conventional textiles. These characteristics appeared at the beginning of the last century, due to the emergence of new textile fibers and scientific research. A technical textile can be described as any product made of textile material whose technical performance and functional properties take precedence over aesthetic or decorative characteristics (Byrne, 2000). The consumption of technical textiles has increased rapidly over the last few years, due to enormous consumer demand and the evolution of trade regimes aimed at active sectors such as health, sport and the military. The global technical textile market size was estimated to be 176.6 billion $ in 2019, with a compound annual growth rate (CAGR) of 4.5% between 2020 and 2027 (source: Grand View Research) (Figure 1).
