Yarn embedded type multilayer non-woven fabric structure and manufacturing equipment thereof

Abstract

The invention discloses a yarn embedded type multilayer non-woven fabric structure. The yarn embedded type multilayer non-woven fabric structure comprises an upper-layer fiber net and a lower-layer fiber net, and is characterized in that an embedded yarn fiber net is arranged between the upper-layer fiber net and the lower-layer fiber net; the upper-layer fiber net, a middle-layer fiber net and the embedded yarn fiber net are compounded through needling to form a multi-layer composite structure; the embedded yarn fiber net comprises warps, upper-layer wefts and lower-layer wefts; and the warps are embedded, and the upper-layer wefts and the lower-layer wefts can be metal yarns. Special yarns can be selected as required for the yarns embedded in the fiber net, the fiber net embedded with the yarns is used as a middle layer to be subjected to composite needling with other fiber net layers, and the finally formed non-woven fabric has corresponding special performance, so that the excessive use of the special yarns is avoided, and the performance obtained by using the special yarns as the raw material of the non-woven fabric is obtained, the structure is simple, and the cost utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a yarn-embedded multilayer nonwoven fabric structure and manufacturing equipment thereof. Background technique [0002] With the gradual development of non-woven materials in recent years, the application fields have become more and more extensive, and the demand for high-strength and functional non-woven fabrics has gradually increased. The performance of nonwoven fabrics made by existing technological methods is not enough to meet these needs, which hinders the further promotion of functional nonwoven materials. [0003] For example, the patent application number CN201520936764.1 discloses a spunbonded nonwoven fabric production line, which forms a spun-netting system through a spinning system and a web-forming machine. The web curtain tensioned on the driving roller, the production line uses multiple sets of spun-bonded web systems to change the single spun-bonded we...

The performance of nonwoven fabrics made by existing technological methods is not enough to meet these needs, which hinders the further promotion of functional nonwoven materials

[0003] For example, the patent application number CN201520936764.1 discloses a spunbonded nonwoven production line, which forms a spinning system through a spinning system and a web forming machine. Web-forming system, under the outlet of the spun-laid system, there is a web-forming curtain tensioned on the driving roller. The production line uses multiple sets of spun-laid systems to change a single spunbonded web into a multi-layer spunbonded web. The fiber web structure is reinforced into a spunbonded nonwoven fabric on the production equipment at one time, and then fibers of different raw materials, fineness, and colors can be formed into a laminated spunbonded nonwoven fabric; The bonding strength between different layers will decrease with time, and it cannot be applied to the compounding of special functional materials, such as metal wires, etc.
