The invention provides a method for directionally constructing a micro-nano porous structure between fibers of a fabric so as to enhance the radiation cooling performance of the cotton fabric. In particular to a Janus knitted fabric with radiation refrigeration and one-way moisture conduction functions and a preparation method and application thereof, the front side of the Janus knitted fabric is hydrophilic cotton yarns, and the back side of the Janus knitted fabric is synthetic fibers; after weaving is completed, the reverse side of the Janus knitted fabric is coated with a polymer solution containing inorganic micro-nano particles, and the distance gt of the synthetic fibers is regulated and controlled; the diameter of the inorganic micro-nano particles and the spacing of the synthetic fibers are gt The polymer solution is directionally distributed to the cotton yarn layer due to the spacing of the hydrophilic cotton fibers, and then a micro-nano porous structure is formed among the cotton fibers through non-solvent induced phase separation. According to the Janus knitted fabric prepared by the invention, a micro-nano porous structure is formed in situ between cotton fibers, the surface texture and macrostructure characteristics of the fabric are not influenced, the original hand feeling and hydrophilicity of the fabric are kept, and the Janus knitted fabric has an excellent radiation cooling function.

This application relates to the field of fabric printing technology, and more specifically, to a method for printing 3D patterns on fabric and its products, comprising the following preparation steps: designing a pattern: designing a pattern according to requirements; preparing templates: preparing complementary and interlocking convex and concave double templates according to the pattern, wherein the convex template corresponds to the raised area of ​​the pattern, and the concave template corresponds to the recessed area of ​​the pattern; molding: placing the part of the fabric to be printed between the convex and concave double templates, molding, removing, and obtaining an uneven pre-treated fabric; printing: inkjet printing on the uneven pre-treated fabric, fixing the color, and post-processing to obtain a 3D patterned fabric. Through the above process, a 3D three-dimensional printed fabric with a distinctly tangible convex and concave feel, realistic visual three-dimensional effect, good softness and breathability is obtained, effectively solving the technical problem that the three-dimensional effect and wearing comfort cannot be achieved simultaneously in existing physical modification technologies.
