Detailed Description
To facilitate an understanding of the invention, the invention is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This 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.
The first embodiment is as follows:
referring to fig. 1, in the present embodiment, an apparatus for producing an MSM nonwoven wiping cloth includes a first web forming machine 1, a collecting roller 2 and a second web forming machine 3, wherein the collecting roller 2 of the present embodiment may be disposed in a single manner or in two opposing manners, which is not limited herein, and may be adaptively configured according to actual production cost and production requirements.
In this embodiment, the first web forming machine 1 is provided with a spunbond machine 11, a pre-press roll 12 and a first suction unit 13, wherein spunbond fibers ejected from the spunbond machine 11 form a spunbond layer a on the web forming surface of the first web forming machine 1, the first suction unit 13 is located below the web forming surface of the first web forming machine 1 and aligned with the spunbond machine 11, and downward suction air is formed below the spunbond machine 11 by the first suction unit 13, so that the ejected spunbond fibers can be adsorbed and attached to the first web forming machine 1, and better web formation is achieved. A pre-press roll 12 is located downstream of the spunbond machine 11, the pre-press roll 12 of this embodiment is a heatable smooth roll, and the spunbond layer a is compacted by the roll surface of the pre-press roll 12 in cooperation with the first web forming machine 1 to form a relatively flat spunbond layer a.
In this embodiment the first web former 1 ends adjacent the collecting cylinder 2 in order to transfer the spunbond layer a to the collecting cylinder 2 and to be transported around the roll surface of the collecting cylinder 2. The collecting drum 2 is provided with a suction area 211 and a blowback area 212 on the circumferential surface, i.e., a negative pressure suction is formed on the periphery of the suction area 211 and a positive pressure blowing is formed on the periphery of the blowback area 212. The first melt-blown component 4 is arranged in the vicinity of the suction area 211, wherein the spun-bonded layer a receives the melt-blown fibers which are sprayed by the first melt-blown component 4 and are attached with hydrophilic oil agent in the suction area 211 through negative pressure suction in the suction area 211, so that the melt-blown fibers are laid on the spun-bonded layer a to form a first melt-blown layer b, and the first melt-blown layer b and the spun-bonded layer a can be preliminarily attached under the action of the negative pressure suction. The first melt-blown layer b and the spunbond layer a are overlapped and conveyed around the roll surface of the collecting roller 2, and finally turned over and transferred to the second web forming machine 3, so that the overlapped spunbond layer a and the first melt-blown layer b are vertically arranged on the second web forming machine 3.
The spunbonded layer a with high strength is used as a receiving medium to receive the melt-blown fibers, so that the cloth breaking caused by overlarge tensile force of a cloth cover in the production process can be reduced, and meanwhile, the melt-blown fibers can be effectively prevented from being stained on the roller surface of the collecting roller 2 and can be better formed into a net (the main reason of adopting the mode is that 1, the melt-blown fibers are easy to be stained in small gaps on the roller surface of the collecting roller 2 due to small diameter, and 2, the melt-blown fibers are low in strength, and if only the melt-blown layer exists, the quality problems such as tearing or scraping are easy to occur).
In addition, the periphery of the blowback area 212 is covered with a suction bellows 213, thereby effectively removing the residual fibers attached to the surface of the collecting drum 2 by the positive pressure blowing force of the blowback area 212 and the suction action of the suction bellows 213, and cleaning the surface of the collecting drum 2; meanwhile, the suction air box 213 sucks and concentrates the residual fibers, so that the residual fibers can be prevented from diffusing into the environment to cause air pollution.
In this embodiment, the second web former 3 is provided with a first hot air drying unit 6, a second melt-blowing machine, a second suction unit 51 and a second hot air drying unit 7, the first hot air drying unit 6 and the second hot air drying unit 7 are box-shaped structures with hot air circulation, high-temperature hot air is circulated in the box body through an external heating device and a fan, and a mesh belt of the second web former 3 supports a non-woven fabric layer to be arranged in a penetrating manner to perform hot air drying treatment through the box body. Specifically, the first hot air drying unit 6 is configured to perform drying treatment on the stacked first meltblown layer b and spunbond layer a to take away surface moisture, so that a layer of hydrophilic crystals is distributed on the fiber surface. The spunbond layer a receives the meltblown fibers with the hydrophilic finish sprayed from the second meltblown on the second web former 3, and the meltblown fibers are formed into a second meltblown layer c in which the spunbond layer a and the first meltblown layer b are sequentially laminated. The second suction unit 51 is positioned below the web forming surface of the second web forming machine 3 and aligned with the second melt blowing machine, and downward suction air is formed below the second melt blowing machine by the second suction unit 51, so that the sprayed melt blown fibers can be adsorbed and attached to the spunbond layer a, and web formation is better. Further, the second hot air drying unit 7 is used for drying the stacked second melt-blown layer c, the spunbond layer a and the first melt-blown layer b to take away the surface moisture, so that the surface of the fiber is covered with a layer of hydrophilic crystal.
In the present embodiment, the second meltblown layer c, the spunbond layer a and the first meltblown layer b are sequentially laminated and combined, and then the combined layers are fed into a consolidation device 8 disposed downstream of the second web former 3 for consolidation, wherein the consolidation device 8 of the present embodiment may be, but is not limited to, a hot rolling mill, an ultrasonic consolidation machine, a spunlace consolidation machine, and the like.
For ease of understanding, the production apparatus described above is further explained below with reference to specific work flows.
In this embodiment, the method includes the following steps:
s1, forming a spunbond layer a on a first web forming machine 1 by spunbond fibers sprayed by a spunbond machine 11, compacting the formed spunbond layer a by a pre-press roller 12, and transferring the formed spunbond layer a to a collecting roller 2 by the first web forming machine 1;

s4, drying the laminated spunbond layer a and the first meltblown layer b by the first hot air drying unit 6 along with the second web former 3;
s5, the dried spunbond layer a and the dried first melt-blown layer b are carried with melt-blown fibers which are sprayed by a second melt-blown component 5 and are attached with hydrophilic oil agents along with a second web former 3, so that the melt-blown fibers form a second melt-blown layer c which is sequentially laminated with the spunbond layer a and the first melt-blown layer b;
and S6, feeding the second melt-blown layer c, the spunbond layer a and the first melt-blown layer b which are laminated together with the second web former 3 into a second hot air drying unit 7 for drying treatment, feeding the dried second melt-blown layer c, the spunbond layer a and the first melt-blown layer b into a consolidation device 8 for consolidation treatment, and finally consolidating to obtain the composite non-woven fabric shown in the attached drawing 3.
Further, the cloth guide roller 22 is arranged between the collecting roller 2 and the second web forming machine 3, and the cloth guide roller 22 is used for drawing the first melt-blown layer b and the spunbond layer a which are laminated to turn over and transfer to the second web forming machine 3 from the collecting roller 2.

In addition, each group of refrigerant channels corresponds to one group of oil atomizing nozzles 43, and the oil atomizing nozzles 43 are communicated with the cold air channel 42, namely, the oil atomizing nozzles 43 are embedded in the cold air channel 42, and atomize the hydrophilic oil to form small liquid which is then sprayed out along with the cold air of the cold air channel 42 to uniformly act on the surface of the melt-blown fiber.
In this embodiment, since the first meltblown module 4 and the second meltblown module 5 use atomized hydrophilic oil, the mesh belt of the second web former 3 is stained with the hydrophilic oil, and the probability of the mesh belt and the product quality are affected if the mesh belt is not cleaned for a long time.
