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.

The present application relates to the technical field of clothing structure design, and discloses a body motion triggered self-heat-dissipation clothing, which comprises a clothing main body, the outer wall of the clothing main body is provided with a foldable structure, the foldable structure comprises a foldable outer layer and a foldable inner layer, the foldable outer layer and the foldable inner layer are connected alternately in sequence, a plurality of air holes are formed in the surface of the foldable inner layer, and the air holes penetrate through the foldable inner layer. The foldable structure formed by the foldable outer layer and the foldable inner layer are connected alternately, the opening change between the adjacent foldable inner layer and outer layer is driven by human motion, and then the air holes are exposed and shielded, so that the problem that the existing windproof and waterproof clothing has poor air permeability and cannot be dynamically adjusted when moving is solved, and the self-adaptive heat management effect that static heat preservation and rain prevention and moving air permeation and heat dissipation can be realized without power driving is achieved.

This invention discloses a method for transplanting old tea seedlings in low-altitude, slightly alkaline soil areas. The method utilizes a two-stage in-situ root pruning technique to rapidly cultivate transplantable mature old tea seedlings; it also creates suitable low-sunlight conditions for tea seedling growth by combining light environment with the surrounding area of ​​the pre-built tea garden; it improves the slightly alkaline soil to a slightly acidic soil suitable for tea seedling growth through soil improvement technology; it uses misting technology to create a microclimate with the same air humidity as the original habitat of the tea seedlings within the tea garden; and it uses high ridges and deep trenches to plant container tea seedlings, ensuring drainage and aeration of the tea tree roots. This effectively solves the problem that the microclimate and soil conditions in low-altitude, slightly alkaline soil areas are unsuitable for establishing tea gardens with good growth.
