Protective clothing protects the body from external influence like heat, chemicals, mechanical hazards, bad weather, etc. by shielding the human body from harsh environmental effects. The maintenance of thermal balance is one of the most important aspects of protective clothing. The study aims to investigate the thermal comfort properties of woven hybrid fabrics produced with high performance core spun yarns. For this purpose, meta-aramid, e-glass, Technora® and Dyneema® fibres were combined using core yarn spinning method in order to enhance the protective performance characteristics. The effects of the core/sheath ratio and type of core materials on the thermal comfort characteristics were investigated and evaluated statistically. The results revealed that, core/sheath ratio, types of core materials have significant effects on thermal comfort characteristics of the fabrics. As the core ratio increases from 19 to 56%, the air permeability of the fabrics increases whereas their thermal conductivity and thermal absorptivity properties decrease. Meta-aramid/E-glass core fabrics can be preferable for protective clothing due to high air permeability and thermal conductivity values.

This paper deals with cut resistance of hybrid woven para-aramid fabrics tested according to the appropriate clause of EN 388 – “Protective Gloves against Mechanical Risks”. Abrasion, puncture and tear resistance properties of the fabrics were also measured. The experimental sample set was plain-woven fabrics made of hybrid yarns composed of staple para-aramid fibres with different core/sheath ratios of various filaments in their structure. The effects of core/sheath ratio and core filament type were investigated. The results revealed that decreasing core–sheath ratio of the hybrid yarns led to the increase in weight and thickness, resulting in improved cut, abrasion and puncture resistance properties. It was confirmed that cut resistance increased with the increase in thickness and weight of the fabric. Para-aramid/Dyneema® fabric had higher cut, abrasion and puncture resistance properties.

In this study, it is aimed to characterize the mechanical and comfort properties of para-aramid protective gloves integrated with yarns having high comfort properties. For this purpose, different gloves have been designed with the combination of para-aramid and Type A (a blend of 85% polyester and 15% cotton fibres), Type B (polyester yarn with a cross-shaped cross section) or Type C (a channeled polyester yarn) yarns by using plating knitting technique. Cut resistance, body movement comfort (elasticity), thermo-physiological comfort (air permeability, thermal conductivity and water vapor permeability—WVP) and moisture management properties of these gloves were tested and evaluated statistically. The results revealed that fabric produced with para-aramid yarns in the face and back sides (P/P_b) exhibits higher cut protection performance. Since these fabrics have lower elasticity, moisture transport capacity, thermal conductivity and WVP values, the use of para-aramid yarn as inner layer of the fabric (next to skin) leads to an uncomfortable feeling. Using Type C yarn as back material (next to skin) provides enhanced characteristics in terms of thermo-physiological comfort and moisture transport capacity. Also this fabric supports body movement comfort with a good elasticity property while its cut protection performance preserves at the same level like fabric produced with para-aramid yarns in the face and back sides (P/P_b).

Research on the triboelectric phenomenon and its use in so‐called triboelectric generators (TEG) has often led scientists to study the various parameters involved in the production of electricity induced by the contact and friction of textile structures. Although the use of textile materials and structures to build textile‐based TEGs is of particular interest, thanks to the advantages they can offer, however, the parameter of ambient humidity acts intensively on triboelectricity, affecting their electric power outcomes. This study investigates the performance of purely textile‐based materials used in a TEG measuring device which combines vertical and sliding modes as if they are part of a wearable garment. Six single jersey‐knitted textile samples, of identical yarn linear densities, are prepared. One material (para‐aramid) is used as the reference sample and it is paired with the rest (cotton, modal, polyester, wool, and acrylic). Consequently, five material combinations are available for measuring under various relative humidity conditions. Through these test series which reflect how a textile‐based TEG would operate under real conditions when embedded in a garment, the results reveal the big impact of ambient humidity on the triboelectric voltage outcome.

Studies in the field of elasticised woven fabrics made of Co/ PBT yarns indicate great potential of PBT use in woven fabrics. Weaving experiments demonstrate that elasticity of Co/PBT fabrics gained after treatment depends not only on woven fabric settings but also on onloom settings. Therefore, it is difficult to predict precisely the degree of shrinkage of the Co/PBT fabric after treatment. Six samples of woven fabrics were produced, three samples with the pretreated core spun Co/PBT weft, each in a different weave. Other three samples were woven with untreated core spun Co/PBT weft, in the same weaves and afterwards the samples were treated. The results indicated big differences between samples with pre-treated Co/PBT yarns in weft direction and samples treated after weaving.

Para-aramid fibers, known for their remarkable strength and thermal stability, are frequently employed in protective textiles for military and aerospace applications. However, continuous exposure to ultraviolet (UV) radiation can damage their protective characteristics. This study analyzes the ultraviolet protection factor (UPF) and UV transmittance of woven fabrics produced from 30/2 Ne spun para-aramid yarns in the warp and 10 Ne core-spun yarns in the weft. The weft yarns consisted of three sheath fibers—para-aramid, meta-aramid, and polyester—in combination with different specialty core materials. The results show significant differences in UPF before and after UV exposure, with para-aramid sheaths giving the highest improvement. UV exposure caused structural changes in the fibers, resulting in increased UV protection, particularly in fabrics with para-aramid sheaths. This study concludes that the combination of para-aramid fibers with specific core materials significantly enhances UV protection, making them well-suited for applications in high UV exposure environments.
