Embodiment 1

[0030] Please refer to figure 1 Shown, be the production line of this example, comprise: mesh belt equipment, comprise mesh belt 10, be driven by the first drive roller 9 and the second drive roller 11; 3. The first air-laid device 5 and the second jet-spinning device 7 . In the advancing direction of the mesh belt, the spinning outlet of the first spunbonded spinning equipment 1, the spinning outlet of the first melt blown spinning equipment 3, the spinning outlet of the first air-laid device 5 and the first The spinning outlets of the two-jet spinning equipment 7 are arranged sequentially; the mesh belt 10 keeps the directional transmission, and in the direction of the continuous directional transmission of the mesh belt 10, first the spunbond fibers 2 output by the first spunbond spinning equipment 1 are spread on the mesh. On the belt 10, a layer of spunbond fiber layer is laid; when the mesh belt device 10 advances to the spinning outlet of the first melt-blown spinning ...

Embodiment 2

[0039] On the basis of the above-mentioned embodiment 1, according to the needs, a second spunbond spinning equipment is added, and its spinning outlet is arranged at the end of the moving direction of the mesh belt, and the second spunbond fiber is laid on the second melt-blown fiber layer layer, forming a superposition structure of the first spunbond fiber layer, the first meltblown fiber layer, the first kapok fiber layer, the second meltblown fiber layer and the second spunbond fiber layer from bottom to top to form a composite thermal insulation material. The weight ratio of the five layers is adjusted to 15:10:50:10:15. Because the kapok fiber and melt-blown fiber are clamped and fixed by the spunbonded fiber layer with better strength, the structure is stable and not easy to shift; it is suitable for application.

Embodiment 3

[0041] On the basis of the above-mentioned embodiment one, according to the needs, a second spunbond spinning equipment is added, and its spinning outlet is arranged at the end of the moving direction of the mesh belt; the spinning outlet of the first air-laid device is arranged at the second After the spinning outlet of the first spunbond spinning equipment, it is the spinning outlet of the first melt-blown spinning equipment, and then the second air-laid device is added to cancel the second melt-blown spinning equipment. In this way, each device lays the net on the mesh belt in turn, forming a superposition of the first spunbond fiber layer, the first kapok fiber layer, the first meltblown fiber layer, the second kapok fiber layer and the second spunbond fiber layer from bottom to top . The weight ratio of each layer from bottom to top is set to 12:30:16:30:12.

Abstract

The invention discloses a melt-blown fiber and kapok fiber online compositing manufacture method and a thermal insulation material made of melt-blown fiber and kapok fiber composite. The manufacture method mainly includes the steps: a first melt-blown fiber net forming, namely laying a net on a net belt or fiber layer to form a first melt-blown fiber layer by the aid of first melt-blow spinning equipment; a first kapok fiber net forming, namely laying a net on the first melt-blown fiber layer to form a first kapok fiber layer by the aid of a first air flow net forming device; and adhering the first melt-blown fiber layer and the first kapok fiber layer due to intrinsic residual temperature of melt-blown fibers of the first melt-flown fiber layer. During online compositing, the melt-blow fibers and the kapok fibers are automatically adhered to form a stable composite structure. Advantage complementation of the melt-blow fibers and the kapok fibers enables the thermal insulation material to have fine heat insulating effects of the kapok fibers and high elastic resilience and breathability.

Description

【Technical field】 [0001] The invention relates to a composite fiber material, in particular to a thermal insulation material in which melt-blown fibers and kapok fibers are combined on-line and a manufacturing method thereof. 【Background technique】 [0002] Kapok fiber is the fruit fiber of several plants in the Malvaceae Kapok family. It is a single-cell fiber that is attached to the inner wall of the kapok capsule shell and developed and grown from the inner wall cells. Generally, the length is about 8-32 mm and the diameter is about 20-45 μm. It is the thinnest, lightest, highest hollow and warmest fiber material among natural ecological fibers. Its fineness is only 1 / 2 of that of cotton fiber, but its hollow rate reaches over 86%, which is 2-3 times that of ordinary cotton fiber. It has the characteristics of smooth, antibacterial, moth-proof, mildew-proof, soft, not easy to tangle, impermeable, non-heat-conducting, ecological, warm-keeping and strong hygroscopicity. ...
