Abstract:One critical property of a nanofibrous structure is the wicking behavior in contact with liquids. This work's purpose is fabrication and investigation of tensile and wicking properties of a newly designed three‐layer nanofibrous yarn consisting of polyamide 6/poly(L‐lactic acid) (PA/PLLA) with a similar idea to Bobtex spun yarn structure in which adhesion between core (PA) and sheath (PLLA) is provided with a thin layer of polymeric thin film. The tensile strength and strain decreased 32 and 46%, respectively,… Show more
“…23 The vertical wicking test for three-layer composite nanofibrous PA/PLLA yarn reveals that at short times, the capillary rise kinetics follow the Lucas-Washburn law, and an increase of the take-up velocity leads to an increase of wicking height. 24 The yarn structure on liquid moisture transport behavior of ring, rotor and vortex yarns was discussed by Lu et al 25 The effects of twist level and tensile strain on the vertical wicking properties of helical-shaped elastic ring-spun yarns containing metal wire were investigated by Wang et al 26 Note that, textile fabrics (e.g. woven, knitted, braided, etc.)…”
The liquid transport capacity in a fibrous textile is of great crucial in comprehensively assessing the final moisture management. In this work, several materials were prepared based on cotton rovings by regulating some technological parameters such as twist and ply number, and the effects of the above key parameters on vertical wicking behavior of cotton roving-based materials were investigated. To effectively improve the wicking rate of materials, three hydrophilic schemes were introduced. The experimental results indicated that the maximum vertical wicking height was obtained when samples treated with a mixed solution of 1.5% JFC and 3% NaOH. Subsequently, several cotton roving-based materials were fabricated based on the optimized hydrophilic treatment. It was found that, the as-prepared materials exhibit a twist-reduced wicking effect, and a ply number-strengthen effect. Furthermore, the underlying mechanisms in the above two cases were unraveled. Finally, our prepared cotton roving-based materials served as a nutrient absorbing medium were demonstrated. Such work provides certain support for an in-depth understanding of wicking behavior of microporous textile structures.

“…Nanofiber yarns offer significant potential for enhancing moisture management in intelligent textiles. A key advantage of nanofiber yarns is their ability to transport moisture . The intricate structure of nanofiber yarns, composed of densely packed nanofibers, enables capillary action to draw moisture away from the skin. , This capillary wicking effect swiftly transfers moisture along the yarn’s length, promoting efficient evaporation and maintaining a comfortable microclimate close to the body.…”
The rapid advancement in nanofiber technologies has revolutionized the domain of yarn materials, marking a significant leap in textile technology. This review dissects the nexus between cutting-edge nanofiber technologies and yarn manufacturing, aiming to illuminate the pathway toward engineering advanced textiles with unparalleled functionality. It first discusses the fundamentals of nanofiber assemblies and spinning techniques, primarily focusing on electrospinning, centrifugal spinning, and blow spinning. Additionally, the study delves into integrating nanofiber spinning technologies with traditional and modern yarn fabrication principles, elucidating the design principles that underlie the creation of yarns incorporating nanofibers. Twisting technologies are explored to examine how they can be optimized and adapted for incorporating nanofibers, thus enabling the production of innovative nanofiber-based yarns. Special attention is given to scalable strategies like centrifugal and blow spinning, which are spotlighted for their efficiency and scalability in fabricating nanofiber yarns. This review further analyses recently developed nanofiber yarn applications, including wearable sensors, biomedical devices, moisture management textiles, and energy harvesting and storage devices. We finally present a forward-looking perspective to address unresolved issues in nanofiber-based yarn technologies.
