In general, mushroom is a nutrient-requiring microorganism that does not have photosynthesis and uses organic carbon. These mushrooms have higher nutritional value than normal vegetables, and are effective against hypertension, diabetes, etc., and especially have anticancer effect.

As a method of cultivating mushrooms, there is known a method of growing trees using hardwoods such as hardwoods and a method of cultivating them in a facility having certain facilities. However, it is difficult to purchase logs because the recovery rate of mushrooms is low compared to the amount of raw materials, and the medium is cultivated in a certain facility by putting the medium into various kinds of containers, The cultivation method is being used.

In the plant cultivation method, bag cultivation is generally used in which a medium prepared by inoculating a seed bacterium into a sawdust medium is cultivated in a bag or the like. At this time, a plug is inserted into the opening of the bag and the filter is combined to provide breathability and hygroscopicity.

However, since the filter is not standardized, as shown in FIG. 7, the bulk cotton cotton or synthetic resin cotton such as PP or PE is used as a filter to be used as a filter. However, when the operator tears a small size It is troublesome to tear it several times and the working environment is poor due to scattered dust generated when it is torn, and it is difficult to reuse the used cotton and the like once.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention of the user, the operator, or the precedent. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1 is a block diagram showing an embodiment of a method for manufacturing a filter for cultivating mushroom cultures according to the present invention, FIG. 2 is a view showing a state where banding and cutting are performed in the cutting apparatus of the present invention, 1 is a view showing a state in which heat treatment is performed in the rotary drum of the invention.

First, the filter (1) for cultivating mushroom seeds according to the present invention is inserted into a cap used for encapsulating mushrooms to provide breathability, hygroscopicity and elasticity. Conventionally, cotton, PE, PP, It is standardized according to the size of the stopper to close the stopper to simplify the process of bumping, and it is easy to reuse.

1 to 3, the method for manufacturing a filter for culturing mushroom seeds according to the present invention comprises: a step S1 of providing a false twist yarn; and a step of forming a polyester twist yarn 10 , A step S2 of forming the fiber bundle 10 (10), a step S2 of bending the fiber bundle 10 to a banding chamber 11, a step S4 of cutting the bundled fiber bundle to a predetermined length, ) Into the rotary drum 200, and heating and subjecting the rotary drum 200 to heat treatment.

In the step S1, a polyester false twist yarn excellent in stretchability is used. The polyester false twist yarn is produced by preparing a multifilament having a polyester of 475 denier / 96 filament melt-spun at a temperature of 190-194 ° C at a low speed, And processed into 300 denier / 96 filaments.

At this time, a low melt spinning speed of 800 to 1,000 m / min is preferable because it can increase the elasticity or bulging property.

The step S2 is to form the fiber bundle 10, which is obtained by kneading 1,000 to 3,000 polyester false-twist yarns of the step S1.

The steps S3 and S4 are for bending the fiber bundle 10 into the banding chamber 11 and cutting the bundled fiber bundle 10 to a predetermined length. The banding chamber 11 is a polyester false twist yarn Can be exemplified.

Here, it is possible to perform the cutting after the banding at a predetermined interval, or alternatively, the banding and the cutting may be alternately performed.

The steps S3 and S4 may be performed through the trimming apparatus 100, for example.

The cutting apparatus 100 includes a pair of feed cylinders 130 and a plate shaped feed unit 110 disposed in front of the feed cylinder 130 and having a feed port 111 for feeding the fiber bundle 10, A cutter 150 disposed at the rear of the feed cylinder 130 and cutting the fiber bundle 10 having passed through the feed cylinder 130, And a bending unit 120 that binds the fiber bundle 10 to the banding chamber 11 between the inlet port 111 and the transfer cylinder 130.

The fiber bundle 10 drawn out through the inlet port 111 is conveyed when the transfer cylinder 130 rotates while being placed between the pair of transfer cylinders 130.

The feeding part 110 is formed with a feeding port 111 for feeding the fiber bundle 10 into the cutting device 100. The feeding port 111 is formed in a tubular shape having a narrower outlet side than the inlet side, The bundle 10 is drawn out in a compressed state at the loading port 111. [

4 is a cross-sectional view illustrating an inlet of the present invention. Referring to FIG. 4, a heat ray 111a is formed on the outer circumferential surface of the inlet 111 to heat the fiber bundle to approximately 50 to 70 ° C. In addition, a spiral groove 111b is formed on the inner surface of the input port 111 so that the fiber bundle 10 passing through the spiral groove 111b can be rotated or twisted along the spiral groove 111b.

If the fiber bundle is preheated or twisted at the inlet as described above, compression can be performed more smoothly, so that a fiber bundle close to a sphere can be formed by the restoring force or elasticity at the time of cutting.

Referring again to FIGS. 1 to 3, since the fiber bundle 10 formed in step S2 is merely a state in which a plurality of false twists are combined, if the fiber bundle 10 is bent and cut in a state of being uncompressed by the input port 111, There is a problem of deterioration.

The bending unit 120 includes a fixed body 121 disposed in a circumferential direction of the loading port 111 and fixed to the supply unit 110, a rotating body 123 rotatably coupled to the fixed body 121, ).

A bearing 126 is provided between the fixed body 121 and the rotating body 123. A rotary bar 124 having a bent structure is formed on one side of the rotating body 123, A bobbin 125 wound with the bending chamber 11 is rotatably coupled.

On the other hand, a belt 127 is fastened to the outer peripheral surface of the rotating body 123.

One side of the belt 127 is fastened to a rotating motor (not shown), and the other side is fastened to the rotating body 123 to transmit rotational force to the rotating body 123.

When the rotating body 123 rotates, the bobbin 125 bends while revolving around the fiber bundle 10 supplied through the inlet 111. At this time, the transfer cylinder 130 does not rotate .

It is preferable that the fiber bundle 10 is wound 7 to 9 times in the banding chamber 11 because the banding yarn is continuously cut in a state in which the banding yarn is not cut in the present invention , So that the banding thread is not loosened during the transferring or storage after the banding.

When banding is performed on the fiber bundle 10, the bundle is passed through the pair of transfer cylinders 130, and cut by the cutter 150.

That is, the fiber bundle 10 is bent at the front side with respect to the transfer cylinder 130, and is cut at the rear side. The cutting is performed at the center of the neighboring banding chamber.

At this time, the banded yarn 11 is bundled in the central region of the cut fiber bundle 10a, and both ends are free ends, so that they are stretched by elasticity and become substantially spherical. The length and diameter of the cut fiber bundle may be about 4 to 6 cm. However, it may be increased or decreased according to the size of the cap.

In step S5, the cut fiber bundle 10a is put into the rotary drum 200 for heat treatment, and the diameter of the cut fiber bundle 10a is reduced by 10 to 25% through heat treatment, They are curled and tangled together to form a cotton-like structure.

In the step S5, the rotating drum 200 is heated while being heated to 150 to 200 DEG C for 5 to 20 minutes. When the rotating drum 200 is heated to less than 150 DEG C, curling is not easily performed, ° C., the fiber bundles are partially melted and aggregated, so that the air permeability and hygroscopicity are rapidly lowered.

In addition, when the rotary drum 200 is heated without stirring, the heating is locally performed and smooth heat treatment is not performed.

The rotating drum 200 is provided with an opening that can be opened and closed at one side thereof and a heating means such as a heating wire 201 is installed at the outer circumferential surface thereof. 203 are connected.

Hereinafter, a more preferred embodiment of the filter for cultivating mushroom seeds according to the present invention will be described in more detail.

1. Polyesters are melt-spun at a temperature of 194 DEG C at a spinning speed of 900 m / min to produce multifilaments of 475 denier / 96 filaments and then subjected to flamming to provide a false-twist yarn of 300 denier / 96 filaments.

2. Prepare a fiber bundle of 1,800 strands of polyester random yarn.

3. Bundle the bundles of fibers into nylon yarns at intervals of 5 cm eight times, and then cut with a cutter to prepare bundles of fibers having a length of 5 cm.

4. Insert the cut fiber bundle into a rotating drum and heat it at 180 ℃ for 10 minutes while rotating.

FIG. 5 is a photograph of a filter for culturing mushroom seed culture prepared according to Example 1 of the present invention, and FIG. 6 is a photograph showing a state in which a filter for culturing mushroom seed culture of Example 1 is inserted into a stopper.
