Figure 1 shows a felt manufacturing process according to the present invention, Figures 2 to 11 show a device for realizing the manufacturing process, described in detail from the first step to the ninth step as follows.

1st process

The first step is the other side and the mixing step for obtaining the static elimination felt.

Referring to FIG. 2, non-clothing academic fibers, which are raw materials, are injected into the raw material feeding conveyor 11 of the other surface and the mixing device unit 10. Non-apparel chemical fibers (hereinafter referred to as raw fibers) are, for example, cotton-like, and three of these raw fibers are introduced.

The first raw material fiber is polyester fiber (1), the second raw material fiber is antistatic (conductive) acrylic fiber (2), and the third raw material fiber is polyester low melting point fiber (3).

The first and third raw material fibers (1) and (3) may be referred to as general chemical fibers, and the second raw material fiber (2) is coated with copper on a fibrous structure, and the second raw material fiber (2) itself generates electricity. By absorbing and removing static electricity, various problems caused by static electricity are prevented.

In addition, the copper component possessed by the second raw material fiber (2) plays a role of antibacterial, deodorizing action as already known in the academic world.

However, when only the second raw material fiber (2) is used as a static elimination felt, it is not possible to have various functions and physical characteristics such as felt strength and flexibility or elimination performance according to the amount of static electricity generated, and thus the use of the felt is decreased and the static electricity is unnecessarily increased. Having a raising function results in inefficiency and inefficiency.

Therefore, in the first step, the mixing ratio of the first, second, and third raw fiber (1), (2), and (3) is calculated in accordance with the intended use of the felt, and the raw material injection moulder (11) is provided in an amount corresponding to the ratio. To be supplied.

The first, second, and third raw material fibers 1, 2, and 3 supplied are introduced into the other surface chamber 12 and transferred to the other surface conveyor 13 by the transfer conveyor 13.

The other surface conveyor 14 is caught in the other surface needle 14a, such as a needle, and is conveyed in an upward direction, and the upper surface conveyor 14 is in contact with the other surface needle 15a of the other surface roller 15 installed to correspond to each other.

At this time, the other surface conveyor 14 and the other surface roller 15 are rotated in opposite directions to each other, so that the first, second, and third raw fiber (1) (2) (3) are in a state of being torn in pieces, Becomes

Therefore, the first, second, third raw fibers (1) (2) (3) are mixed with each other inside the other surface chamber 12, and the mixed raw fibers as described above are referred to as fibers (4). In the following description, detailed descriptions and drawings will be omitted for driving means such as a motor, a belt, a pulley and a chain, and a chain gear in all devices.

Therefore, the fiber 4 is conveyed by the guide conveyor apparatus 16 so that a predetermined amount may be guided. Guide conveyor device 16 is composed of a first conveyor (16a) and a second conveyor (16b), by which one of the conveyors are installed with an inclination angle so that a constant amount of fiber can be supplied in the next process In the following, these devices will be described only as guide conveyor devices.

The fiber 4 supplied from the guide conveyor device 16 is conveyed while being compacted along the compaction roller 17 having the toothed outer circumferential surface 17a. In other words, the compaction roller 17 is chopped the fiber (4) because the outer peripheral surface has a sawtooth irregularities outer peripheral surface (17a), thereby becoming a softer fiber (4) state.

The fiber 4 which has passed through the compaction roller 17 is transferred to the fiber standby unit 20 which realizes the next process by the wind blown by the blower 18.

2nd process

The second step is to wait for fibers, and the amount of fibers processed in the third step and the amount of fibers processed in the first step are different from each other. That is, since the amount of treatment in the first process is large, and the amount of treatment in the third process must be constantly maintained at a constant amount and requires a lot of processing time, the fiber is held between the first process and the third process and the constant amount of fiber is There is a need for a fiber standby process that can be supplied to the process.

3 shows a fiber standby device unit 20 performing a second process.

The fiber waiting unit 20 has a fiber waiting room 21 in a large space, and the fiber 4 is blown by the wind into the fiber waiting room 21 and accumulated.

The fiber 4 of the fiber waiting chamber 21 is supplied to the fiber supply chamber 23 by a pair of supply rollers 22 and 22 'having a rake 22a.

The lower part of the fiber supply chamber 23 has a conveying conveyor 24, and the fiber 4 falling from the supply rollers 22 and 22 ′ is transported into the fiber supply chamber 23 by the conveying conveyor 24.

The fiber 4 of the fiber supply chamber 23 is transferred to the web device 30 which is the next process by the wind generated from the fiber blower 25 installed in the upper portion.

3rd process

The third process is a web process in which fluffy fibers are produced in a web state such as woven paper.

Therefore, the fiber supplied in the second step is a step of measuring the weight so that a constant amount of fibers is supplied, the fiber supplied is to be manufactured in a web state having a constant thickness.

4 shows a web device section 30 to realize a web process. The fiber 4 blown from the fiber standby unit 20 is supplied to the waiting chamber 31 and the fiber 4 of the waiting chamber 31 is caused to fall down by the supply roller 32 which is intermittently rotated.

The dropped fibers 4 are stacked on the measuring plates 33 and 33 ', where the weight of the fibers 4 is measured.

That is, the measuring plates 33 and 33 'are in a state in which the weight of the fibers 4 stacked thereon is loaded, and sag in the lower direction by the weight. Therefore, the sensor detects the amount of deflection of the measuring plate. When the deflection of the measuring plate is set, the measuring plate 33 (33 ') is opened by the measuring plate operating part by rotating the counterclockwise downward direction as shown in the virtual line. By being a certain amount of fibers (4) are dropped to the lower and is conveyed by the guide conveyor device (34). Here, the sensor and the measuring plate operating portion of the measuring plates 33 and 33 'are generally known, and thus, the drawings and detailed description thereof will be omitted.

The fiber 4 conveyed by the guide conveyor device 34 is supplied to the first web roller 36 by a pair of guide rollers 35 and then supplied to the second web roller 37. The first and second web rollers 36 and 37 have an outer circumferential surface having a toothed outer circumferential surface 36a and 36b, and are conveyed in a state of being bitten by the guide rollers 38 of the outer portion.

Therefore, as the fiber 4 is compacted in the process of passing through the first and second web rollers 36 and 37, the web 5 becomes a kind of fabric.

The web 5 which has passed through the second web roller 37 and the guide roller 38 is supplied to the web stacking device portion 40 for realizing the fourth process conveyed by the conveying conveyors 39 and 39 '. .

The fourth step is a web lamination step for stacking the webs 5 manufactured in the third step in multiple layers.

In this web lamination step, the webs 5 are automatically laminated so that the number of layers is calculated in advance according to the thickness of the nonwoven fabric 6 to be obtained.

5 shows a web stacking device section 40 for realizing a web stacking process.

The web 5 supplied by the conveying conveyors 39 and 39 'is conveyed by the upper conveyor 41 to be supplied to the stacked feeder 42.

The stack feeder 42 is reciprocated in the left and right directions along the main shaft 43. Here, the driving unit for the reciprocating motion is well known in the art, and thus the drawings and descriptions thereof will be omitted.

Therefore, when the stacking feeder 42 supplies the web 5 to the lower conveyor 44 at the bottom while reciprocating left and right, the web 5 is stacked and transported in multiple layers.

5th process

The fifth process is a web fabrication process in which a single nonwoven fabric 6 is produced by bringing the web 5 laminated in multiple layers to a desired thickness and being fabricated.

The composite fabric is made by interweaving fibers in a laminated web 5 state, and the fibers are entangled with each other, so that the fibers are entangled so that the thickness of the nonwoven fabric 6 is improved.

FIG. 6 shows a web stacking device unit 50 for realizing a web stacking process, wherein the stacked webs 5 supplied from the lower conveyor 44 of the web stacking device unit 40 are guide rollers 51 and guide conveyors. The device 52 and another guide roller 53 are conveyed to the air bubbler 54.

The mixing device 54 has a myriad of mixing needles 56 reciprocating at high speed in the up and down directions by the up and down reciprocating driving part 55. In addition, the mesh member 58 supported by the guide 57 is fixedly installed at the portion opposed to the mixing needle 56 and the web 5 stacked in contact with the mesh member 58 passes therethrough. have.

Therefore, when the mixing device 54 is driven, the stacking needle 56 repeatedly stabs the stacked webs 5, whereby the fibers of the stacked webs 5 are pushed down by the stacking needles 56. As a result, the thickness becomes gradually thin as they are mixed in an entangled state.

7A and 7B illustrate a process performed in the web combining process and the apparatus unit. The web 5 laminated before the composing process starts has a thick thickness of " H " In this state, when the needle is repeatedly stabbed (about 500 times per minute) by the mixing needle 56, the fibers (fibers) are entangled as shown in Fig. 7B, and the thickness becomes thin as "h". As the fibers are entangled, the state in which the tensile force becomes good is increased.

Such a process of encapsulation is difficult to complete completely with one encapsulation device 54, so as shown in FIG. 6, another encapsulation device 54 ', or three to four encapsulation devices (not shown) are continuously provided. In addition to the conventional mixing process is made, if any one of the air accumulator (54) from the top to the bottom, the needle 56 is raised and lowered, the other air gun (54 ') is operated by the reverse Encourage the process of inclusion.
