Abstract
The invention discloses a moisture-permeable and easily-dried sleeping bag fabric and a preparation method thereof, wherein modified resin is dissolved in tetrahydrofuran, added with PA6, uniformly mixed, dried and added into a double-screw extruder for extrusion, and modified nylon is prepared; mixing modified nylon, formic acid and methylene dichloride until the modified nylon is completely dissolved to prepare spinning solution, and carrying out electrostatic spinning and hot-press molding on the spinning solution to prepare nylon fabric; the nylon fabric is soaked in the fabric treatment liquid, soaked and dried, soaked in the copper sulfate solution, soaked and dried to obtain the nylon fabric, the fabric is treated by the fabric treatment liquid, so that the surface of the fabric is coated with a layer of graphene/polyacrylate film, the waterproof effect is improved, the surface of the fabric and the surface of the graphene/polyacrylate film are soaked in the copper sulfate solution, the terpyridine structure is contained on the surface of the fabric and the surface of the graphene/polyacrylate film, and can be matched with copper ions, so that a plurality of extremely thin metal layers are formed, the waterproof effect of the fabric is improved, and the adhesion effect of the graphene/polyacrylate film and the fabric is also improved.
Description
Technical Field
The invention relates to the technical field of preparation of moisture-permeable and easily-dried fabric, in particular to a moisture-permeable and easily-dried sleeping bag fabric and a preparation method thereof.
Background
Along with the increase of outdoor activities of people, the sleeping bag is a necessary device for outdoor camping and municipalities, nylon is a common sleeping bag fabric, nylon is a synthetic material, so that the sleeping bag has better mechanical strength and toughness, and even has higher stretching and compression angles than metal, and the characteristics determine that the nylon fabric has higher usefulness and wide application scenes, and the nylon is often used for producing waterproof fabrics due to the characteristics, but due to the poor water absorption capability of the nylon, the sleeping bag can feel very oppressed when resting in the sleeping bag, meanwhile, the nylon is weak in antistatic capability, and can generate electrostatic absorption after friction, so that the sleeping bag is absorbed on the skin surface, and further the use comfort is affected.
Disclosure of Invention
The invention aims to provide a moisture-permeable and easily-dried sleeping bag fabric and a preparation method thereof, which solve the problems that the sleeping bag fabric in the prior art has good waterproof effect but poor moisture-permeable effect, and the use comfort is easily affected by static electricity in the use process.
The invention aims to solve the technical problems:
