Study on developing a multi-integrated textile system: investigating the liquid loading and release performances of hollow fiber yarns

Textile fabrics have a long history of use for a wide range of applications that satisfying the needs of livelihood. In this era of modernization and high technological advancements, the use of textiles has spread to include using man-made and nonconventional textiles. Among them, hollow fiber-based textiles have great application prospects due to their high surface-area-to-volume ratio, high loading capability, high active surface area and high permeability of the porous layer. Herein, the liquid loading and release performances of various hollow fiber yarns with different parameters (i.e. spinning methods, yarn count, loading amount, releasing rate, etc.) under optimized negative pressure are presented. Results showed that the hollow fiber vortex spun yarn (with yarn count Ne 10/1) had the highest loading ability under negative pressure. Moreover, the amount of liquid loaded into the yarns first increased rapidly and then the rate became slower with an increase of loading time and finally tended to a stable value. In addition, as the release time increases, the amount of liquid released from the hollow fiber yarns became higher and the release rate became lower. These findings provide an important foundation for the development of the multi-integrated textile system, which is comprises the controllable loading and delivery of various types of active substances and chemicals.
