This invention relates to the field of regenerated
fiber fabric preparation, specifically to a bio-based regenerated
fiber breathable and
moisture-wicking fabric and its preparation method. The invention involves adding uniformly dispersed bio-based
nanocellulose whiskers to a bio-based
regenerated cellulose spinning solution, stirring until homogeneous, and then
spinning the fabric. The entire process involves no additional chemical reactions; stable bonding is achieved solely through natural
hydrogen bonds between
cellulose macromolecules and
whiskers. The
whiskers possess high-density hydroxyl groups, constructing continuous hydrophilic
moisture-wicking channels. Simultaneously, their high-rigidity one-dimensional rod-like structure forms a permanent supporting framework within the
fiber. In the dry state, the stable fiber pores ensure high breathability, while in the wet state, they limit the swelling and deformation of
cellulose macromolecules, thus preventing pore closure. This invention solves the problems of
moisture absorption, swelling, and pore blockage in conventional regenerated fibers, as well as decreased moisture wicking and breathability in wet conditions. It also improves mechanical properties, has a simple process, is easily scalable for industrial production, and is entirely bio-based and biodegradable, making it
environmentally friendly.
