Graphene multifunctional superfine fiber multilayer non-woven fabric and preparation method thereof

Abstract

The invention belongs to the technical field of functional non-woven fabric processing, and discloses a graphene multifunctional superfine fiber multilayer non-woven fabric and a preparation method thereof. Graphene multifunctional superfine fiber and low-melting-point fiber are respectively opened through a variable-frequency card clothing opener, are then sent to a wind power mixer to be subjected to secondary wind mixing opening, are next conveyed into different cotton boxes, and are then conveyed into a zero-wind-pressure cotton net collecting device in a distribution mode that a middle layer is the low-melting point fiber and upper and lower layers are the graphene multifunctional superfine fiber, so that the fiber uniformly falls onto a collecting bar; the collected fiber is subjected to physical milling and pre-adhesion to form a fiber net; then, the fiber net is conveyed to a thermal binding machine to be shaped; and the graphene multifunctional superfine fiber multilayer non-woven fabric is obtained. The multilayer non-woven fabric of a three-dimensional reticular structure can be obtained by using a simple method of wind mixer opening, zero-wind-pressure cotton net collection, physical milling and thermal shaping. The multilayer non-woven fabric has the characteristics of light weight, softness, warmness and closed-fit performance.

Description

technical field [0001] The invention belongs to the technical field of functional nonwoven fabric processing, and in particular relates to a graphene multifunctional ultrafine fiber multilayer nonwoven fabric and a preparation method thereof. Background technique [0002] Warm floc or multi-layer non-woven fabric is an important auxiliary material for making clothing, home textiles and other daily textiles, which can play a good heat insulation effect. Traditional thermal insulation sheets usually use natural filling materials such as cotton batting, wool, and down. Among these filling materials, down has the best warmth retention, followed by wool, and cotton batting is the worst. Thermal insulation made of cotton or wool is easy to absorb moisture and has poor resilience. After a period of use, its thermal performance will drop significantly, and it has been gradually eliminated. The thermal insulation flakes made of down are light in weight, have good resilience and good...

Problems solved by technology

Although the above-mentioned technologies have achieved good performance, they still have single functions, high material requirements (for example, special-shaped hollow microfibers, three-dimensional crimped hollow fibers, etc.), and complicated preparation methods (for example, use of messy sticks or fiber nets). The drafting effect of the stretching machine makes the fiber web form a three-dimensional network structure, etc.)
