As shown in Fig. 1 (a), the hair of aquatic birds such as ducks or geese is composed of down in the chest and feathers in the neck or wing. In addition, as shown in (b) of FIG. 1, the feather of a duck or goose has a shaft positioned in the center and a rachis provided on the upper part of the shaft, and on both sides of the shaft and the feather shaft. It is composed of a downy barb, an after feather, and a barb provided.

The present invention relates to a method of manufacturing a down fiber by removing a feather shaft and a feather band from the feather, and extracting a downy barb, an after feather and a barb, and the like, and a down fiber manufactured therefrom.

The manufacturing method of the down fiber according to the present invention for solving the above problems, goes through the steps as shown in FIG. 2 . A closer look at this is as follows.

[Step 1]

The manufacturing method of the down fiber according to the present invention first undergoes a first step (S100) of sorting discarded feathers through a down sorting process. In the prior art, down having good quality in the selection process of down or goose down is used as a filler for clothing or bedding, and feathers of poor quality as shown in FIG. 1 (b) are sorted and discarded.

The present invention is to recycle feathers, such as ducks or goose, which have been conventionally discarded as described above, and recycle them into down fibers. Feathers are selected from the fur. The feathers selected in the first step (S100) have the same shape as in (a) of FIG. 4 .

[Step 2]

As described above, the feathers collected through the first step (S100) of sorting the conventionally discarded feathers and the like are subsequently subjected to a washing process as the second step (S200).

That is, in the second step (S200), after selecting feathers such as ducks or geese that are conventionally discarded and disposed of, they are washed in an automatic washing machine as shown in FIG. steps to remove it.

Typically, 2.5% by weight of down or goose down is impurities such as filth, and impurities such as filth must be removed through the second step of the present invention.

Therefore, the second step (S200) is 50 ~ 70 ℃ water in the neutral detergent 1 ~ 5 o.w.f. Washing is carried out for 20 to 30 minutes at a liquid ratio of 1:100.

That is, it is particularly advantageous to use a neutral detergent in the second step (S200), and when a neutral detergent is used in the second step (S200), less rinsing is required to remove residual oil and fat from the feathers, so wastewater etc. can be reduced.

[Step 3]

The feather that has undergone the second step (S200) is then subjected to a third step (S300) of cutting the feather using a high-speed spiral cutting machine as shown in FIG. 3C.

That is, the feather washed through the second step (S200) is subjected to a third step (S300) of cutting the feather using a high-speed spiral cutting machine including a cutter board having a diameter of 3 to 8 mm. . The feather cut by performing the third step (S300) has a shape as shown in (b) of FIG. 4 .

Looking at this in detail, 40 ~ 60 kg of feathers are fed into the high-speed spiral cutting machine at a time, and the feather cutting process is performed while controlling two cutter boards at a speed of 20 ~ 40 rpm/min.

By uniformly and loosely distributing the feathers in the chamber of the machine when the cutter board is controlled at the above speed, it is possible to maintain the stability of the feathers and prevent the feathers from clogging in the high-speed spiral cutter.

In the third step (S300) of the present invention, the size of the feather is cut to 10 mm or less by using a cutter board having a diameter of 3 to 8 mm as described above.

Also, according to the present invention, before performing the third step (S300), it is possible to supply the feathers at a uniform density through a feather uniform density feeding machine that supplies the feathers with a uniform density when feeding the feathers to the high-speed spiral cutting machine.

[Step 4]

The feather, which has been cut to 10 mm or less in length through the third step (S300), is subjected to a down fiber extraction process using an extractor as shown in FIG. 3 (d) as a fourth step (S400). The extraction process refers to the step of extracting down fibers having a shape and size similar to that of down from feathers cut to a size of 10 mm or less in a high-speed spiral cutting machine.

In the fourth step (S400) of extracting the down fiber manufactured through the third step (S200), the down fiber manufactured through the first ultra-high speed multi-axis feather separation extraction machine and the second ultra-high speed multi-axis feather separation extraction machine is subjected to various grades. can be classified and extracted.

The fourth step (S400) will be described in detail. In the third step (S300), the feathers cut to a size of 10 mm or less are the downy barb and the hind auricle shown in FIG. 1(b). It exists in the form of a mixture of (after feather) and barb, and shaft and rachis.

According to the present invention, the fourth step of extracting down fibers, that is, downy barb, after feather, and barb from the mixture, may consist of primary extraction and secondary extraction.

In the fourth step (S400) of extracting the down fiber, the mixture is filled in a chamber provided in an ultra-high-speed multi-axis feather separation extraction machine, and then air is supplied to the chamber to produce down, such as a downy barb, which has a light specific gravity. It separates the fiber and the heavy-duty quill shaft and feather stem.

That is, when the wind of a certain wind speed is supplied to the chamber filled with the mixture, the down fibers such as the light downy barb float in the chamber, and the shaft and the rachis with heavy specific gravity are placed under the chamber. gather in the part.

A fourth step of extracting the down fiber by separating the down fiber and the blade shaft separated by air as described above may be performed.

That is, according to the present invention, 100 kg of the mixture is filled in a chamber provided in a high-speed multi-axis feather separation extractor, and air is supplied into the chamber at a wind speed of 900 to 1,300 rpm/min to proceed with the primary extraction. do. The primary extraction is performed for 90 to 110 minutes, and at this time, about 50% of the down fiber is extracted from the mixture. The first extracted feather has a shape as shown in FIG. 4(c).

The mixture in which the primary extraction has been performed is again supplied with air at a wind speed of 900 to 1,300 rpm/min to perform secondary extraction for 90 to 110 minutes. In the secondary extraction, 55% or more of the down fiber is extracted, and the secondary extracted feather has a shape as shown in FIG. 4(d).

After the fourth step including the primary extraction and the secondary extraction of extracting the down fibers as described above is completed, a step of selectively re-washing the extracted down fibers may be added. The re-washing process may be performed in the same manner as in the second step.

[Step 5]

In the present invention, as described above, a fifth step (S500) of de-cancelling the down fiber extracted through the fourth step (S400) is performed.

Duck or goose feathers contain a large amount of oil and fat and bacteria, dust, worms or soil, so a detoxification process is required.

In particular, if the oil and fat contained in the feather is not removed, odor or bacteria may be generated, so the fifth step ( S500) is performed.

In the fifth step (S500) according to the present invention, harmful VOCs contained in feathers and a peculiar smell of down are first collected by using a deodorant. When the deodorization step is performed using a deodorant as described above, excellent deodorization performance can be exhibited.

Thereafter, the feathers that have undergone the deodorization step are disinfected, and the disinfection process is carried out for 10 to 20 minutes using dry heat steam in a temperature range of 120 to 140 ℃.

As described above, it is possible to manufacture a high-quality down product having excellent palatability and marketability through the deodorization and disinfection process in the fifth step.

The deodorant used in the deodorizing step of the fifth step (S500) according to the present invention may be an inorganic metal or an organic metal.

That is, the deodorant according to the present invention is at least one selected from the group consisting of a metal phosphate including a colloidal inorganic metal complex supported on copper or zinc metal titanium dioxide, zirconium phosphate, titanium phosphate, aluminum phosphate, calcium phosphate, etc. It is preferred for use for deodorizing feathers.

The fifth step (S500) according to the present invention can be performed by mixing with water so that the concentration of the deodorant is 1 to 5 o.w.f., and then putting it in an automatic washing machine together with feathers.

The content of the deodorant is 1 o.w.f. If it is less than, it is difficult to obtain sufficient deodorizing properties, and 5 o.w.f. If it is exceeded, an increase in manufacturing cost may occur. Therefore, it is preferable that the content of the deodorant is 1 ~ 5 o.w.f. in consideration of the balance between the deodorizing properties for feathers and the manufacturing cost.

After the deodorization process is performed as described above, it is possible to completely deodorize, disinfect, and dry down fibers by performing a disinfection treatment for 10 to 20 minutes using dry heat steam at 120 to 140 ° C.

[Step 6]

The down fiber that has undergone the fifth step (S500), which is the detoxification and detoxification step as described above, is then subjected to a sixth step (S600), which is a process of removing metal impurities contained in the down fiber.

According to the present invention, the sixth step (S600) may be performed by dividing it into two steps, and the first step may be performed using a horizontal metal removal machine. And the second step may be performed using a vertical metal removal machine.

That is, the horizontal metal removal machine has an inlet into which the down fiber is put, and applies a horizontal metal removal machine to which 300 permanent magnets are attached from the down fiber moving at a speed of 1 to 3 kg/min. metal impurities are removed.

The horizontal metal removal machine removes metal impurities with a large particle size by using a magnetic field of a permanent magnet from a horizontally traveling down fiber.

The down fiber passing through the horizontal metal removal machine is then passed through a vertical metal removal machine to which 400 permanent magnets are attached.

The vertical metal removal machine to which 400 permanent magnets are attached deeply removes metal impurities from the down fiber moving at a speed of 1 to 3 kg/min.

That is, the vertical metal removal machine removes metal impurities of a smaller size from the down fiber.

When the sixth step (S600) of removing the metal impurities is performed as described above, the manufacturing of the down fiber according to the present invention is completed.

As described above, the down fiber from which the metal impurities are removed may be packaged to have an appropriate size and weight required by the customer.

The down fiber of the present invention manufactured through the above steps can be used as a filling material for down clothing or bedding like normal down. That is, typically, the fill power of duck or goose down is 440 (in ³ /30 g), and the fill power of the down fiber according to the present invention is 450 (in ³ /30 g) or more. Therefore, it can be used as a filler for down clothing or bedding.

In addition, since it is possible to produce 50% by weight or more of down fibers from all feathers, the price is low. Therefore, by using the down fiber as a filler, it is possible to produce clothing products with excellent price competitiveness as shown in FIG. 5A and bedding products as shown in FIG. 5B.

That is, according to the present invention, it is possible to manufacture down products such as environmentally friendly clothing products and bedding, and also, by recycling discarded or discarded feathers, etc., there is an effect of saving resources and protecting the environment. In particular, live plucking, which is the act of pulling live ducks and geese, can be reduced, thereby avoiding controversy over animal cruelty.

Although the present invention has been described with reference to the embodiment shown in the drawings, which is only exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
