Detailed Description
To facilitate an understanding of the present invention, it is described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1 and 2, in the present embodiment, a device for preparing a two-component high-loft nonwoven fabric includes a spunbond system 1, a drawing path 2, and an arcuate diffusion path 3. The spunbond system 1 of the present embodiment is used for forming and spraying bicomponent fibers, wherein, the spunbond system 1 shown in fig. 2 includes an extruder, a filter, a spinning pump, a spinner and a tractor, the extruder, the filter and the spinning pump of each of the spunbond machines are provided with two sets, bicomponent materials are respectively input from the two sets of extruders and merged in the spinner, and a bicomponent spunbond web is finally formed; the structure and principle of the above components are not described herein and belong to conventional elements.
In this embodiment, the drawing channel 2 is located below the spunbond system 1, the drawing channel 2 and the arc-shaped diffusion channel 3 are arranged up and down, and the arc-shaped diffusion channel 3 is communicated with the outlet of the drawing channel 2. The bicomponent fiber ejected by the spun-bonded system 1 is drafted into filaments in the drafting channel 2 and then enters the arc-shaped diffusion channel 3.
In this embodiment, the arc diffusion channel 3 is an arc-shaped sealing structure, wherein a cold air port 31 inclined downward is arranged at an inlet of the arc diffusion channel 3, and a cold air flow is blown into the arc diffusion channel 3 from the cold air port 31; the temperature of the cold air flow is room temperature, generally 25-30 ℃; the middle part of the arc-shaped diffusion channel 3 is provided with a hot air port 32 which inclines upwards, and hot air flow is blown into the arc-shaped diffusion channel 3 from the hot seal port, and the temperature of the hot air flow is 60-80 ℃. Furthermore, the flow rate of the hot air flow is smaller than that of the cold air flow, so that the double-component fibers after being drafted into filaments can be smoothly sent out in the arc-shaped diffusion channel 3.
Secondly, fully cooling the just-fed bicomponent fibers by a cold air flow inclining downwards, and drawing the bicomponent fibers downwards along an arc-shaped diffusion channel 3; during the downward drafting, upward resistance is formed on the bicomponent fibers by the upward inclined hot air flow, and partial fibers are curled and branched by utilizing different heat shrinkage rates of two component materials in the bicomponent fibers, so that the bicomponent fibers form long fibers and fine fibers, and finally the effect that the bicomponent fibers are fluffy and soft is achieved.
Further, the arc-shaped diffusion channel 3 adopting the arc-shaped design can increase the downward drafting duration of the bicomponent fiber, and can enable the bicomponent fiber to be curled and drafted as much as possible.
In this embodiment, a web-forming machine 4 is further included, and the outlet of the arc-shaped diffusion path 3 is arranged adjacent to the web-forming surface of the web-forming machine 4, whereby the bicomponent fibers sent out through the arc-shaped diffusion path 3 are transferred to the web-forming machine 4 to be web-formed.
In this embodiment, the device further comprises a traction compression roller 6 arranged at the outlet of the arc-shaped diffusion channel 3 and a negative pressure suction unit 5 arranged close to the outlet of the arc-shaped diffusion channel 3, and the traction compression roller 6 is matched with the web forming surface of the web former 4 to perform pre-pressing treatment on the bicomponent fibers and the negative pressure suction unit 5 performs suction and traction action on the bicomponent fibers, so that the bicomponent fibers can be attached to the web forming surface to form a web.
Further, the negative pressure suction unit 5 of the present embodiment is externally connected with an air suction port of a negative pressure vacuum machine (not shown), so as to generate a negative pressure acting force for sucking the bicomponent fibers.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way.
