Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for producing a sliver which is a pre-process for producing a yarn in spinning,
In particular, the present invention relates to a method for manufacturing sliver when using used futon as a raw material.

[0002]

2. Description of the Related Art In the past, futon was a valuable item, and was a recycled product to be re-used. However, in recent years, such re-work has not been performed, and when it is old, it has almost been discarded as oversized garbage. The ratio of used futons in bulky garbage is very high, and each municipality has difficulty in treating used futons, which are collected in large quantities as bulky garbage. Most of the collected futon is incinerated, but it is difficult to burn because of its thickness. Good condition can be reused as futon in some cases, but the reuse rate is much lower than the amount incinerated. For this reason, various attempts have been made to reuse used futons by trial and error, but one of them is to use as a raw material of yarn.

[0003]

Problems to be Solved by the Invention However, futon fibers are cotton staples which do not have spinning in mind in the first place, and if they are made of cotton wool, they are extremely short fibers. Only a yarn having a low tensile strength was produced, and it was recognized that the yarn was not suitable as a raw material for the yarn. Recently, futon of synthetic fibers such as polyester has been distributed. This synthetic fiber futon is not as short as cotton wool, but it is also manufactured for cotton laying, so it is too thick to get enough entanglement between the fibers to make the yarn. It was recognized as unsuitable as a raw material. Furthermore, the fibers of the used futon are densely compressed, and even if the futon is used as it is, the carding treatment itself as a premise of spinning the yarn cannot be sufficiently performed, and it is difficult to obtain a uniform sliver. The present invention has been made to solve the problems contained in the conventional technology. Its purpose is to provide a method for manufacturing slivers using used futon that enables the carding treatment as a premise of yarn production to use used futons as raw materials and to produce strong and uniform yarns. Is what you do.

[0004]

Means for Solving the Problems In order to solve the above problems, in the invention of claim 1, the outer skin and the binding thread of the used futon are removed, the futon is taken out, and the cotton is subjected to an opening process.
The gist of the present invention is to add a fiber for spinning of long fiber to the opened futon cotton and apply a blending process to the blended cotton to obtain a sliver by performing a carding process on the blended cotton. . In such a configuration, first, the outer skin and the binding thread of the futon are removed, and the cotton is opened with only the futon. Then, the long fibers are added to the opened cotton and mixed to obtain a mixed cotton. Then, a sliver is obtained by performing a carding process. Here, the cotton-opening treatment corresponds to, for example, a cotton-opening treatment by a cotton-opening machine or a hair-repelling machine. In addition, the mixing process corresponds to, for example, a process performed by a mixer, a blender, a cotton opener, or a napping machine. The fibers for spinning include natural fibers and chemical fibers. As the natural fiber, the natural fiber refers to a plant fiber and an animal fiber, and examples thereof include a seed fiber, a kidney fiber, a leaf fiber, a hair fiber, and a silk fiber. Recycled fibers, semi-synthetic fibers, and synthetic fibers are used as chemical fibers.
For example, rayon, cupra, acetate fiber, polyamide fiber, polyester fiber, polyacryl fiber, polyethylene fiber, polyvinyl chloride fiber and the like can be mentioned. The long fiber herein means a fiber having an average fiber length longer than 30 mm. The average fiber length of the long fibers varies depending on the thickness of the yarn that can be spun and the mixing ratio of the futon wool and the chemical fibers, but is about 35 to 120 mm. In addition, a short fiber means a fiber whose average fiber length is shorter than 25 mm. Also,
As the chemical fiber for spinning, one having a thickness of 1 to 8 denier is used. As for the thickness, it is possible to use a denier having a larger length as long as the fiber is longer. However, in order to obtain a sufficient tensile strength, it is most preferably about 1.5 to 3 denier.

According to a second aspect of the present invention, in addition to the constitution of the first aspect of the present invention, in the mixing treatment, 30% by weight or more and less than 90% by weight of the opened futon wool is used as a chemical fiber for spinning long fibers. More than weight percent 7
The gist is that less than 0 weight percent is added to make the total of both fibers 100 weight percent. The reason why the amount of the futon is set to 30% by weight or more is that if the futon is less than 30% by weight, the feeling of the futon becomes diminished in the finished product, and the distribution ratio of the new chemical fiber as the reuse of the used futon is changed. Is too much. From this viewpoint, the amount of the futon is preferably 50% by weight or more. On the other hand, the reason for making the futon less than 90% by weight is mainly in terms of strength. If the compounding ratio is higher than this, yarn having low tensile strength will be spun. Since the strength varies depending on the average fiber length of the long fibers, the use of chemical fibers having a longer fiber makes it possible to mix up to less than 90% by weight of futon, but the futon is preferably less than 85% by weight.

According to a third aspect of the present invention, in addition to the constitution of the first aspect of the present invention, the mixing ratio of the futon wool and the chemical fiber is set to the ratio of the first aspect in the mixing step, and the natural fiber for spinning long fiber is further used. Is added in the mixing process. This is, for example, 60% by weight of futon cotton,
When the chemical fibers for spinning are 40% by weight, it is assumed that 20% by weight of natural fibers for spinning are blended with 80% by weight of the mixed fibers having such a distribution ratio. According to this structure, the mixing ratio of the chemical fibers is reduced, and a yarn having a more natural texture can be obtained. The definitions of long fibers and natural fibers for spinning are the same as described above.

[0007]

According to the first aspect of the present invention, a sliver can be obtained from used futon cotton, which has been conventionally difficult to reuse as a yarn, and the yarn can be spun from the sliver. In the invention described in claim 2,
In addition to the effects of the invention described in claim 1, a sliver having the feel of cotton and sufficient strength can be obtained from used futon cotton, and a yarn can be spun from this sliver.
According to the invention described in claim 3, in addition to the effect of the invention described in claim 2, the compounding ratio of the chemical fiber is reduced, and a yarn having a more natural texture can be obtained.

[0008]

An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the binding thread 5 for preventing the outer skin 3 and the cotton from being biased is removed from the used futon 1, and only the futon 7 is left. Futon wool 7 of the present embodiment is 100% cotton wool. As shown in FIG. 2, this futon 7 is
Is placed on the lattice conveyor 9. A cotton opener 11 is provided downstream of the first lattice conveyor 9. The futon 7 conveyed by the first lattice conveyor 9 is supplied into a cotton opener 11, scraped off by a cotton opener drum 12, and adjoined by a first fan 13.
4 is transported to the downstream by air. The futon 7 that has been opened by air and that has been opened is collected in the collection unit 15. Normally, Collection Building 1
A collection bag (not shown) is set in 5, and the opened futon cotton 7 is sorted by the collection bag so as to be transported by a predetermined amount. The process of transporting the futon 7 from the first lattice conveyor 9 to the cotton opener 11, opening the cotton, and collecting the cotton in the collection bag corresponds to a cotton opening process.

Next, as shown in FIG. 3, on the second lattice conveyor 17, the opened futon 7 in the collection bag and the separately prepared polyester fiber 19 (average fiber length of about 100 m)
m, average thickness of about 2 deniers). Futon cotton 7
The weight distribution ratio between the futon cotton 7 and the polyester fiber 19 is 65% by weight, and the weight of the polyester fiber 19 is 35% by weight. When placing the futon cotton 7 and the polyester fiber 19 on the second lattice conveyor 17, the two materials are placed alternately in consideration of the ease of mixing. (If both materials are not stacked alternately, it is preferable to convey the mixture to the blender 21 after passing through the mixer). A mixing machine 21 is provided downstream of the second lattice conveyor 17.
Are arranged. The dispenser 21 is dispensed while the futon cotton 7 and the polyester fiber 19 are sandwiched by the dispensing drum 22 and the walkers 23 arranged on the outer periphery thereof.
Behind the walker 23, a stripper 24 for removing the fibers caught between the needles is provided. The walker 23 and the stripper 24 constitute one set, and usually 3 to 4 sets are arranged on the outer periphery of the mixing drum 22. A second fan 25 is disposed downstream of the mixing drum 22. The prepared blended cotton 27 is air-fed by the second fan 25 downstream in the second duct 28. Futon cotton 7 and polyester fiber 1 are placed on the second lattice conveyor 17.
The process from the loading of 9 to the blending by the blending machine 21 corresponds to the mixing process.

As shown in FIG. 3, the distal end of the second duct 28 is located above the hopper 31 of the measuring device 30. The mixed cotton 27 dropped from the second duct 28 and supplied to the hopper 31 has a predetermined amount corresponding to the type of yarn in the measuring device 30 at a predetermined timing at the downstream third lattice conveyor 32.
It is supplied above. The blended cotton 27 conveyed downstream on the third lattice conveyor 32 is a condenser card 35
Supplied to The capacitor card 35 according to the present embodiment includes a breaker 36 and a finisher 37. Mixed cotton 2 with fibers aligned in breaker 36
7 is laterally divided by a condenser tape (not shown) in the finisher 37, is formed into a sliver (shino) 38 by a condenser rubber (not shown), and is wound into a so-called cheese 39. The process from the measurement of the blended cotton 27 by the measuring device 30 to the formation of the sliver 38 corresponds to the carding process. The sliver 38 thus obtained is twisted by a ring spinning machine (not shown) to obtain a spun yarn, and the spun yarn is wound around a paper tube by a winder.

According to the present embodiment, the following effects can be obtained by manufacturing as described above. (1) Used futon cotton 7 which has been said to be unrecyclable by first opening the used futon cotton 7 and allowing it to be blended with the polyester fiber 19 afterwards, because it is not reusable for yarn 7 could be used for yarn. (2) Since the sliver 38 is obtained by setting the futon cotton 7 to 65% by weight and the polyester fiber 19 to 35% by weight, the yarn spun from the sliver 38 retains the strength and the feel of cotton due to the blending of the polyester fiber 19. The recycled yarn has extremely excellent properties. (3) When placing the futon 7 and the polyester fiber 19 on the second lattice conveyor 17, the two materials are alternately loaded in consideration of ease of mixing. Mixing in machine 21 was successfully performed, and compounding machine 2
A mixed cotton 27 in which both fibers are firmly mixed can be obtained without using any other mixing means before feeding the mixed cotton 27 to the raw material 1. (4) Since the used futon cotton 7 is used as raw cotton, contamination of impurities such as garbage is small, and dust removal treatment is not necessarily required.

The present invention can be embodied with the following modifications.・ Since spinning has a unique development in various parts of Japan, the same processing equipment may be called with different names. In the above embodiment, the cotton is opened by the cotton opener 11, but the machine is not limited to the cotton opener 11 as long as the machine can perform the same operation. For example, an anti-hair machine used in manufacturing felt fabrics may be used to open cotton here. -The above process may have some variations depending on the strength, thickness, etc. of the yarn used for production. For example, in the above embodiment, the futon cotton 7 and the polyester fiber 19 are directly supplied to the blender 21 by being laminated.
If both raw cottons are mixed to some extent by a mixer as a pre-stage of the blender 21, the necessity of laminating the futon cotton 7 and the polyester fibers 19 is not necessarily obviated. Further, in the above embodiment, the mixed cotton 27 is weighed through the second duct 28 into the measuring device 30.
However, the second duct 28 may not be used but may be transported to the measuring device 30 by a separate means. In the above embodiment, the sliver is obtained by using the capacitor card 35. However, the capacitor card 35 is only a specific example of performing the carding process, and other card devices can be freely used as long as the carding process is possible. In the above embodiment, the capacitor card 35 has obtained the cheese 39 as a result of the carding process. But,
A combing process may be provided before the cheese 39 is obtained. The drawing may be performed after the carding process or the combing process. When the drawing is performed, a roving process by a roving machine is performed as necessary. In the above-described embodiment, the spinning was performed with the futon cotton 7 at 65% by weight and the polyester fiber 19 at 35% by weight. However, this compounding ratio is an example, and another compounding ratio may be used. In addition, although the thing of 100% of noodles was used also as Futon cotton 7,
Chemical fiber cotton such as polyester may be used. In the above embodiment, the cotton wool 7 and the polyester fiber 19, which is a chemical fiber, are used as the spinning raw material. However, a natural fiber for spinning may be blended in place of the polyester fiber 19. In the above embodiment, the futon cotton 7 and the polyester fiber 1
Although only 9 was used as a spinning raw material, other natural fibers for spinning may be added thereto. In this case, Futon 30
It is preferable to add a natural fiber so as not to affect the blending ratio of the chemical fiber for spinning a long fiber from 10% to less than 70% by weight with respect to the weight percentage of less than 90% by weight. In the above embodiment, the polyester fiber 19 is blended as the chemical fiber for spinning, but other chemical fiber for spinning may be used. For example, rayon is a material that is easily biodegradable when discarded.
The yarn spun from No. 8 is preferable from the viewpoint of environmental protection. -Two or more kinds of chemical fibers for spinning may be blended. -Two or more natural fibers for spinning may be blended. In addition, the present invention can be freely implemented without departing from the gist of the present invention.
