DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a paper thread used for a woven or knitted fabric.

[0002]

2. Description of the Related Art Conventionally, there is known a paper thread in which a paper tape having a width of about 2 mm to 10 mm is twisted and used as a thread. For example, Japanese Patent No. 2,994,209 discloses a paper thread formed by twisting a water-resistant paper tape using a wet paper strength enhancer and a dry paper strength enhancer in combination. By the way, when the above-mentioned paper tape is twisted as it is to form a yarn, there is a problem that the twist is uneven and the shape of the paper yarn is not determined. Therefore, the paper tape is twisted while giving moisture. For example, water is immersed in a sponge or the like, and the paper tape is twisted after supplying water to the paper tape with the sponge or the like.

[0003]

However, in the method in which water is supplied to the paper tape with the sponge or the like, it is difficult to supply water continuously to the paper tape, and a sufficient supply of water to the portion where water is supplied is sufficient. There was a problem in that the twist of the paper tape was uneven in the portion where the twisting was not performed, and the uneven twist could not be completely eliminated.

[0004]

According to a method of manufacturing a paper thread according to the present invention, a paper tape is twisted after steam is applied to the paper tape. Further, the paper yarn manufacturing apparatus according to the present invention is provided with a twisting means for applying a twisting force to the paper tape sent by the paper tape transporting means, and between the paper tape transporting means and the twisting means. And steam supply means for supplying steam.

FIG. 1 is a block diagram showing an embodiment of the present invention.
And FIG. FIG. 1 is a schematic configuration diagram showing an outline of a manufacturing apparatus for realizing the paper yarn manufacturing method of the present invention, and FIG.
FIG. 3 is a perspective view showing a relationship among a feed roller for feeding a paper tape, a heater box, and a paper tape. In the method of manufacturing a paper thread according to the present embodiment, the paper tape 1 is sent to the heater box 3 side as the steam supply means by the feed roller 2 as the paper tape conveying means, and the steam from the heater box 3 is applied to the paper tape 1 after being applied thereto. The paper thread 10 is produced by twisting the paper tape 1. The apparatus for manufacturing a paper thread according to the present embodiment includes a spindle 7 as a twisting means for applying a twisting force to the paper tape 1 sent by the feed roller 2 as a paper tape conveying means, the feed roller 2 and the spindle 7 And a heater box 3 as steam supply means for supplying steam to the paper tape 1.

For example, as disclosed in the above-mentioned Japanese Patent No. 2994209, the paper tape 1 is formed by adding a water-resistant agent to pulp dispersed in water and then making the paper by, for example, 2 mm to 2 mm. It is cut into a width of about 10 mm. This cutting may be performed by a dedicated cutting device in a process before the feed roller 2.

The feed roller 2 has one long rotating roller 2A rotated by a drive shaft 2a, and a plurality of weight rollers 2B, 2B,... Which are allocated to each paper tape and connected by a connecting shaft 2b. It is composed of The rotating roller 2A is formed of a metal roller, and the weight roller 2B is formed of a rubber or other pipe around the metal roller so that the paper tape 1 is not easily cut.
c.

The heater box 3 includes a rotating roller 2A.
, Which is an elongated rectangular box installed slightly below the position of the rotary roller 2A along the axial direction of the rotary roller 2A. A heat insulating material 4 such as styrene foam is attached to the inner wall of the heater box 3. Also, a heater tube 5 is disposed inside,
The stored pure water 6 is heated to generate steam 6H. Further, twisting stops 3b, 3b,... Are provided on the upper edge 3a of the heater box 3 farther from the feed roller 2 corresponding to the position of each weight roller 2B. This twist stop 3b
May be constituted by a rounded corner or the like formed on the upper edge 3a of the heater box 3, or by providing a rounded member such as stainless steel on the upper edge 3a of the heater box 3. You may. Also, the upper edge 3a of the heater box 3
The body itself (that is, the corner of the upper edge 3a) may be used as a twist stop. A steam outlet 3d is formed in the upper surface 3c of the heater box 3 corresponding to the position of each twist stop 3b, and steam from each steam outlet 3d is formed.
It hits each paper tape 1 guided to each twist stop 3b from the position of each weight roller 2B.

Therefore, after the steam hits each paper tape 1 sent by the feed roller 2, each paper tape 1 is guided to each twist stop 3b, and immediately after passing through the twist stop 3b, the steam is supplied and becomes soft. Paper tape 1 becomes spindle 7
The paper yarn 10 is wound around a wooden tube 8 rotated by a spindle 7. The number of twists of the paper thread 10 is usually determined by the rotation speed of the rotating roller 2A and the rotation speed of the spindle 7.

In FIG. 1, reference numeral 9 denotes a disk attached to the wooden tube 8, reference numeral 9a denotes a traveler attached to the outer periphery of the disk 9, and guides the twisted paper thread 10 to the wooden tube 8. Reference numeral 11 denotes an intermediate guide.
Is a drive belt for rotating the spindle 7. Also,
10A shows a state in which the paper tape 1 is twisted after passing through the twist stop 3b.

According to the embodiment, the paper tape 1 softened by the steam is twisted uniformly, and a thin and soft paper thread 10 can be manufactured. In addition, a twist stop 3b is provided so that the twisting force on the paper tape 1 due to the rotation of the spindle 7 is not transmitted from the twist stop 3b to the paper tape 1 on the steam blowing hole 3d side, so that the entire surface of the paper tape 1 is evenly distributed. The paper tape 1 which has been softened by the steam being uniformly applied to the entire surface in this manner is twisted 3b.
Is immediately twisted by the rotation of the spindle 7 immediately after passing through, so that the thin and soft paper yarn 10 that is uniformly twisted as described above can be reliably and efficiently manufactured. Further, since the tape 1 is produced by using a device having a winding mechanism by the spindle 7 via the steam blowing holes 3d and the twist stoppers 3b corresponding to the respective tapes 1 sent corresponding to the plurality of weight rollers 3B. In addition, the above-described paper thread 10 can be simultaneously produced in large quantities with uniform quality.

The paper yarn 10 obtained by the production method of the present invention is
It is used for fabrics such as jackets, shirts, sheets, parasols, hats, towels, and knitted fabrics for various knits, hats, underwear, supporters, socks, and the like.

The fibers used for paper are different from the fibers for clothing such as cotton and hemp, and the fibers are short (the raw material for paper is 2 mm or less in length, and the raw material for Japanese paper is 6 mm in fiber length). As described above, as described above, paper is made by adding a water-resistant agent to pulp dispersed in water and then making paper. In particular, when manufacturing Japanese paper, it is dispersed in water to form a two-dimensional sheet. At that time,
A process called suki (suki) is performed to increase the entanglement of the fibers. In addition, paper is produced by dispersing fibers having a porous structure of only a cell membrane in which the resin content in the fibers is removed by pulping (boiling with alkali) and washed away in water. Accordingly, the paper thread 10 obtained by twisting the paper tape 1 obtained by cutting the paper manufactured as described above as described above has a structure in which the fibers themselves have many voids. Therefore, the paper thread 10 produced according to the present invention has excellent heat insulating properties, excellent moisture absorption / exhaustability, low stickiness, and an ultraviolet blocking effect. In addition, since there is no fluff in structure, it has the characteristics of good touch, gentle to atopic skin, and resistant to abrasion. In addition, since the paper of the material is in a dried state with a small amount of moisture, mold is hardly generated, and microorganisms such as mites are hardly proliferated. In addition, since it has strong water resistance, it can be washed with a washing machine or the like. In this case, 20-3
Withstands washing more than 0 times (washing resistance exceeds cotton),
Tumble drying is no problem, and it becomes softer.
