And a through hole III for communicating the outer hollow part with the inner hollow part is formed in the inner ring part. The polyester filament yarn is composed of the inner ring part, the connecting part and the outer ring part which are integrally formed, air circulation is achieved through the through holes in all the parts, the filament yarn is endowed with good air permeability, and the polyester material has enough holes for air permeability.

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.

The invention relates to a processing method and yarn for adjusting fiber arrangement structure by twisting and shaping. The invention adopts an immersion liquid feeding method to make the outer layer of filaments passing through a liquid feeding device carry solution, and the staple fiber strands are stretched by a stretching mechanism and then enter a primary twisting mechanism for twisting and shaping. The filaments carrying the solution are combined with the staple fiber strands through the primary twisting mechanism and enter a secondary twisting mechanism for twisting and shaping. The filaments are covered by the staple fiber strands under the twisting action and are arranged in a spiral shape under the torsion coordination of the staple fiber strands. After the twisting and shaping, the yarns are cured by a heat treatment device to shape the solution between the filaments and the staple fiber yarns, so that the twisting and torsion of the fibers are twisted and shaped, and at the same time, the surface fibers of the yarns are smoothed, the stress bonding between the filaments and the staple fiber yarns is enhanced, the inner and outer layer structures of the yarns are effectively regulated, the bonding effect between the fibers is greatly enhanced, and the yarn structure and yarn strength are improved.

The invention discloses an electromagnetic shielding material and a preparation method and application thereof.The preparation method comprises the steps that firstly, a cotton fabric is placed in a saturated NaOH solution of bivalent copper salt to be subjected to an impregnation reaction, and a modified cotton fabric is prepared; and washing and drying the modified cotton fabric, and carbonizing to obtain the electromagnetic shielding material. The method is simple in process and reasonable in design, the electromagnetic shielding material with excellent performance can be obtained only through simple dipping and carbonization treatment, the method is suitable for industrial expanded application, and meanwhile the product has good electromagnetic shielding effectiveness based on the copper elementary substance and the carbonaceous material.

The invention relates to a bamboo-wrapped wood flute and a preparation process thereof. The process comprises the following steps: selecting a bamboo pole material which is dried in the shade and stored for 2 or more years and has proper diameter and length; baking and prying the bamboo pole material on a furnace; processing the inner bore of the bamboo rod material into the required inner diameter size on a lathe by using an inner boring cutter to manufacture an outer pipe; a dalbergia wood material is selected, the wood material is processed into a cylindrical wood rod on a lathe, and the outer diameter of the cylindrical wood rod is matched with the inner diameter of the outer pipe; the cylindrical wooden pole is stuffed into the bamboo tube and bonded through glue; an inner bore hole is machined in the cylindrical wood rod through a reamer, and the size of the inner bore hole meets the requirement for the inner diameter size of the flute; the pitch size is determined according to the inner diameter of an inner bore hole machined in the cylindrical wooden pole, then a blowing hole, a film hole, a finger hole, a pitch hole and a sound outlet hole are formed, flute film installation and tone tuning are carried out, and the bamboo-wrapped wooden flute is obtained. The bamboo-wrapped wood flute has high timbre and intonation, and the sounding quality of the flute is improved.
