Abstract
High-performance textiles are crucial in numerous sectors, yet existing materials often fail to meet the dual requirements of sustainability and multifunctionality. Basalt fiber, derived from natural rock through an environmentally friendly process, is renowned for its excellent strength, high-temperature resistance, and chemical inertness. However, its intrinsic brittleness brings great challenges for knitting applications. This study presents a novel and scalable process to develop basalt/cotton (BC) composite yarn for high-performance textile applications. The yarn is obtained using a sustainable manufacturing approach that combines the twist-for-one (TFO) technique with a bio-based sizing. The bio-based sizing not only enhances the mechanical properties of the prepared yarn, yielding a 35.6 % increase in tenacity and a 33.9 % improvement in elongation compared to the unsized BC hybrid yarn, but also imparts several key functionalities to the fabrics. Specifically, knitted fabrics possess a multi-functional profile, integrating superhydrophobicity with a water contact angle of 152.4o, robust ultraviolet protection factor of 265.3, and potent antibacterial activity against S.aureus (99.1 %) and E.coli (97.1 %). Furthermore, the fabrics exhibit a notable 206 % stretchability and excellent tactile comfort. The incorporation of basalt fiber significantly improves the thermal stability of the cotton in BC hybrid fabric, as confirmed by the increased decomposition temperature at 5 % weight loss from 295 °C to 335 °C. These attributes highlight the promising potential of the BC hybrid yarn for sustainable and high-performance textile applications.
