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.)

Abstract

The invention belongs to the technical field of functional non-woven fabric processing and discloses multifunctional graphene superfine fiber multilayer non-woven fabric and a preparation method thereof. Multifunctional graphene superfine fibers and low-melting-point fibers are opened by a variable-frequency card clothing opener, then sent to a wind power mixer for secondary wind mixing and opening, sent to different cotton boxes, and sent to a zero-wind-pressure cotton web collecting device according to the arrangement mode that the middle layer is the low-melting-point fibers and the upper layer and the lower layer are the multifunctional graphene superfine fibers, so that the fibers uniformly fall onto a collecting row; and the collected fibers are physically rolled and pre-bonded to form a fiber web, and then the fiber web is sent to a thermal bonding machine for shaping to obtain the multifunctional graphene superfine fiber multi-layer non-woven fabric. The multilayer non-woven fabric with a three-dimensional web structure can be obtained by using simple methods of wind mixing and opening, zero-wind-pressure cotton web collection, physical rolling and heat shaping. The multilayer non-woven fabric obtained has the characteristics of being light, soft, warm and sticking.

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...
