In recent years, textile materials have increased the demand for eco-friendly and harmless clothing and daily necessities due to the improvement of living standards and the development of civilization. have.

Hanji, which is manufactured using traditional natural fiber material Doc Pulp, is a representative eco-friendly material that is harmless to the human body. It has been spotlighted as a wallpaper for the purpose, and its use is limited to drawing paper, wrapping paper, crafts, etc., and various creations have been required.

Conventional application of textile using Hanji was made by using traditional Korean craftsmanship by fashion craftsmen, either by cutting Hanji's support itself or by cutting the hanji by hand. We faced the problem of limit of production and production.

Recently, a technique for producing a branch by applying a mechanical twist using a ring spinning machine after slitting the base paper to a certain width has been proposed, and the ring spinning machine has the advantage of performing both the twisting process and the winding process, but the ring spinning machine Due to the nature of the group, the size of the branch that can be wound on the cone is limited by the size of the ring, and there is a problem that it cannot be wound by applying a twist to a large amount of paper tape. By requiring a separate post-process connecting the branch offices, there is a problem that productivity is greatly reduced, such as cumbersome work, and require a large number of workers.

The present invention for solving the above problems can be smoothly given to the paper tape, and can be wound in large quantities without being limited to the size of the ring as the conventional twist is given, and also form stability, uniformity and physical properties The purpose is to provide a branch manufacturing method that can produce this excellent branch.

In order to achieve the above object, the present invention provides a method of manufacturing a branch by cutting a feeder to a certain width to form a paper tape and then twisting the paper tape.

In particular, it is preferable that the twisted paper tape contains a certain amount of moisture and then wound up, and more preferably contains the moisture by passing the twisted paper tape through rollers immersed in a water bath.

The tank is divided into an immersion part and an outlet part in which the roller is immersed by a partition wall, and when water is excessively supplied to the immersion part through a supply pipe, excess water is introduced into the discharge part through the partition wall. The water introduced into the discharge portion is preferably configured to be discharged into the discharge pipe.

Hereinafter, the branch manufacturing method of the present invention will be described in detail.

The branch manufacturing method of the present invention comprises a paper tape manufacturing process for cutting paper into a predetermined width, a twisting step for applying twist to the cut paper tape, and a winding step for winding the branch to which the twist is applied.

The paper tape manufacturing step is a step of winding a paper to a bobbin by cutting it to a certain width in order to obtain a branch of a desired number of papers, and is not limited to any specific method in the paper manufacturing method of the present invention. Since detailed description is omitted.

In addition, the tributary referred to here includes both pulp obtained from coniferous trees, broadleaf trees, etc., as well as Korean paper obtained from paper mulberry. In addition, the feeder that can be used in the present invention, such as the use of a functionally processed feeder in the papermaking step or the step before and after the papermaking step, is not particularly specified.

1 is a view schematically showing a twisting step and a winding step of the branch manufacturing method of the present invention, and FIG. 2 is a longitudinal cross-sectional view schematically showing a longitudinal cross-sectional state of the twisting machine.

Next, the twisting step is to dissolve the paper tape 110 wound on the bobbin 10 and at the same time to impart a twist, the paper tape 112 to be dismissed from the bobbin 10 by the feed roller 730 Twisting is imparted by rotating the perforated paper tape in the axial direction of the bobbin after penetrating in the axial direction of the bobbin.

The twisting machine used in the twisting process includes a spindle 310 in which the rotary disk 315 is integrally formed as shown in FIG. 2, a protective container 330 stopped on the spindle 310 and opened on the spindle 310, and a paper tape. Consists of an inlet pipe 350 for axially supporting the bobbin 10 wound around it and guiding the paper tape 112 dismissed from the bobbin 10 to an inlet 312 formed at the upper end of the spindle. The bobbin 10 on which the tape is wound is axially supported by the inlet pipe 350.

The spindle 310 is rotated to one side by a drive member, and thus the rotating plate 315 integrally formed at one side of the spindle 310 also rotates to one side. An inlet 312 is formed at an upper end of the spindle, and an outlet 317 communicating with the inlet 312 is formed at one side of the outer circumferential surface of the turntable 315.

The bobbin 10 on which the paper tape is wound is constructed in the inlet pipe 350, and the paper tape 112 wound on the bobbin and dismantled is passively or actively driven to one side of the inlet pipe 350. After passing through the mounted pliers 370 is introduced into the dead pipe inlet 352 of the dead pipe inlet 350. The paper tape drawn into the threaded inlet 352 of the threaded inlet pipe 350 is drawn into the inlet 312 formed in the upper end of the spindle 310 to the outlet 317 formed on the outer circumferential surface of the turntable 315. Withdrawn.

The paper tape 114 drawn out through the outlet 317 of the rotary plate 315 passes through the balloon guide 390 formed on the upper side of the sloped pipe 350 and then passes through the cone guide 390 to the cone 790 by a winding device. It is wound up.

The paper tape 114 located between the outlet 317 and the balloon guide 390 of the rotating plate 315 is provided with twisting at the same time the balloon is formed by the centrifugal force.

The twisting machine 30 that can be used in the twisting process of the present invention is not limited to the twisting machine, and the paper tape passed through the bobbin by the feed roller in the axial direction of the bobbin passes through the pierced paper tape in the axial direction of the bobbin. All the twisting planes that can be imparted by twisting can be used.

Finally, the winding process is a process of winding the paper tape 116 to which twist has been applied by using the winding device 70, etc., wherein the winding device 70 passes through the balloon guide 390. The traverse guides the branch that has passed through the first guide roller 712 and the second guide roller 714 and the second guide roller 714 to switch the traveling direction of the branch 116 to the supply roller 730. A supply roller 730 for smoothly supplying to the 750, a traverse guide 750 for horizontally moving the branch fed by the supply roller 730, and a cone 790 in contact with the cone 790 It is configured to include a winding drum 770 to wind the branch passed through the traverse guide 750 to the cone 790 by movement.

The branch 116 to which the paper tape is twisted is passed through the balloon guide 390, and then the first guide roller 712, the second guide roller 714, the supply roller 730, and the traverse guide are located on the upper side. Pass 750 sequentially. And the branch passing through the traverse guide 750 to the left and right movement is wound in the cone 790 to the rolling motion in contact with the rotating winding drum 770.

The winding device 70 that can be used during the winding process is not limited to the winding device, and any winding device that can wind the branch uniformly twisted into the cone by the twisting step can be used. .

When winding by twisting paper tape using a ring spinning machine as in the prior art, it is possible to wind up a cob, such as failing to wind a large number of branches in a cob built on the spindle due to the limitations of the size of the ring and the speed of the travella. One winding amount is limited to the size of the ring. Therefore, in order to smoothly produce a product using a branch, a separate auto winder has to be connected to branch offices wound on a plurality of cops.

However, by twisting through the twisting step as in the present invention, and winding the branch twisted by a separate winding device, since the winding amount is not limited to the ring size as in the prior art, a large number of branches can be wound on the cone. As a result, the process may be shortened, such as no need to go through a post-process such as a separate auto-winding process, and the productivity may be greatly improved, for example, a branch may be manufactured by a small work force.

It is preferable to contain moisture by winding the branch to which twist is applied by the twisting step, and this is to obtain a branch having excellent physical properties by uniformly giving a twist of the branch and improving form stability and uniformity. In more detail, if the branch contains moisture, the branch can induce recombination of the pectin component, thereby obtaining a branch having improved form stability and uniformity.

The method of supplying moisture to the branch office may include all other methods such as water supply using a spray, water supply using steam, etc., but using a roller-immersed water tank. It is preferable to contain water in the branch.

3 is a view schematically showing a state in which a water tank in which a roller is immersed between a first guide roller and a second guide roller is installed.

When water is supplied to the branch by using the roller-immersed water tank 90 as shown in FIG. 3, the branch is provided with a uniform twist, and the branch contains a sufficient amount of moisture to induce recombination of pectin. It is possible to obtain a branch having excellent physical properties since its shape is stabilized in such a state.

4 is a perspective view schematically showing a tank in which rollers are immersed, and FIG. 5 is a view schematically showing a state of a tank in which a portion is cut.

The tank is divided into an immersion part 930 and a discharge part 950 in which the roller 976 is immersed by the partition wall 910 as shown in FIGS. 4 and 5, and on one side of the immersion part 930. It is coupled to the supply pipe 932 for supplying water, and is formed in communication with the discharge pipe (952) for discharging the introduced water to one side of the discharge portion (950).

At this time, the height of the partition wall 910 is formed to be smaller than the side wall of the tank by a predetermined amount, or as shown in Figure 4 to form a communication groove 912 on the upper surface of the partition wall 910 by a predetermined amount of the immersion part 930 When water is accommodated, the upper surface of the barrier rib 910 or the communication groove 912 may be formed so as to flow into the discharge part 950.

In addition, the communication port 912 may be formed in place of the communication groove 912 on the upper surface of the partition 910 of course.

As described above, the discharge part 950 is formed in the water tank, and the water contained in the immersion part 930 is continuously or intermittently formed to overflow the discharge part 950, so that the water phase accommodated in the immersion part 930 is formed. There is an advantage that can be discharged to the outside through the discharge unit 950 continuously or intermittently floating pectin, such as dust scattered in the work space.

And the support member 972 is fixedly installed on one side of the tank, the arm member 974 formed by one side is bent downwardly is axially coupled to rotate at one end of the support member 972, optionally the The roller 976 in which a predetermined portion is immersed in the immersion part 930 may be configured to be axially coupled to one end of the arm member 974.

6 is a view schematically showing a state in which the roller member mounted arm member is rotated upward.

In the case where the branch is to be passed between the rollers 976 immersed in the tank by the beginning of work or the thread is trimmed, as shown in FIG. 6, the arm member 974 on which the rollers 976 are mounted is rotated upward. The branch is placed in the groove 997 formed in the 976, and in that state, the arm member 974 is rotated downward so that the roller 976 can be easily moved in the state where the branch is placed. Can be immersed in water.

Hereinafter, the branch manufacturing method of the present invention will be described in more detail with reference to Examples. The scope of the present invention is not limited to the following Examples, and the present technology is within the scope without departing from the technical scope of the present invention. Of course, it can be variously modified by those skilled in the art.

Example 1

Hanji was cut into 2 mm wide, and about 200 g or more of the cut paper tape was wound around the bobbin. After attaching the bobbin wound around the paper tape to the twisting machine, the twist was applied to the paper tape by operating the winding machine, and the twisted branches were wound up by the winding device.

At this time, the rotation speed of the spindle of the twisting machine was controlled so that the twist number was 500 ~ 1000 T / M, and the production speed was 10m / min. No trimming phenomenon occurred during the twisting and winding process, and the paper more than 200g wound on the bobbin. The tape was wound into the cone by twisting once without post-processing.

The branch office thus prepared had physical properties of 40 Nm fineness, 0.6 g / d strength and 2% elongation, and an evenness of about 20 U%.

Example 2

Hanji was cut into 4mm in width, and about 200 g or more of the cut paper tape was wound around the bobbin. After attaching the bobbin wound around the paper tape to the twisting machine, the twist was applied to the paper tape by operating the winding machine, and the twisted branches were wound up by the winding device.

At this time, the rotation speed of the spindle of the twisting machine was controlled so that the twist number was 500 ~ 1000 T / M, and the production speed was 10m / min. No trimming phenomenon occurred during the twisting and winding process, and 200g or more paper wound on the bobbin. The tape was wound into the cone by twisting once without post-processing.

The branch office thus prepared had physical properties of 20 Nm fineness, 0.8 g / d strength and elongation 2.5%, and an evenness of about 20 U%.

Example 3

Unlike Example 1, the first guide roller and the roller are provided with a branch that is twisted by the twisting machine in a state in which a water tank in which the roller is immersed is mounted between the first guide roller and the second guide roller located above the balloon guide of the twisting machine. The immersed water tank and the second guide roller were sequentially passed through, and then the branch to which the twist was given by the winding device was evenly wound on the cone.

At this time, trimming did not occur during the twisting and winding processes, and the paper tape wound over the bobbin was wound in a cone without twisting at a time without post-processing.

The branches thus produced had physical properties of fineness of 42 Nm, strength of 0.9 g / d, elongation 3%, and evenness of 10 U%.

[Comparative Example]

Hanji was cut into 2 mm wide, and about 200 g or more of the cut paper tape was wound around the bobbin. The paper tape wound on the bobbin was twisted with a ring spinning machine and wound around the cobb. At this time, the amount that can be wound up to the cobbed branch is approximately 50g.

As described above, in Examples 1 to 3, a large amount of 200g or more paper tape was twisted at one time and wound on the cone, but in the comparative example, a small amount of 50g paper tape was twisted due to the limit of the diameter of the ring. And since it is impossible to wind up, it is inevitable to connect the branches wound to the plurality of cops by the post-process, the work process is cumbersome, a large workforce is required, and productivity is greatly reduced.

In addition, when water is supplied to the branch which passed through the twisting machine as in Example 3, the twist was uniformly applied, thereby obtaining a branch having excellent physical properties such as strength and uniformity.

As described above, in the branch manufacturing method of the present invention, the paper tape dissolved from the bobbin by the external force passes through the bobbin in the axial direction of the bobbin, and then twists the paper tape in the axial direction of the bobbin, followed by additional winding. By winding a paper tape or a branch imparted with a device, the winding amount is not limited to the size of the ring as in a conventional ring spinning machine, and a large number of branches can be wound on a cone or the like. There is no hassle to give effect. As such, there is no need to connect branches between a plurality of cones as in the prior art, and thus there is an advantage in that productivity is greatly improved, such as no need for a separate device and a work force, and greatly shortening the branch manufacturing time.

In addition, by incorporating a certain amount of moisture into the paper tape to which the twist is applied by the twisting step, the twist is uniformly imparted, thereby obtaining a branch having excellent shape retention, uniformity, and physical properties.

In particular, the twisted paper tape is passed between rollers immersed in a tank containing water to contain moisture, so that the branch contains enough moisture to induce recombination of the pectin. It is stable, and there is an effect of obtaining a branch having excellent homogeneity and physical properties.

The tank includes an immersion part in which the roller is immersed by a partition wall, and a discharge part that overflows when the water is supplied to the immersion part and discharged into the discharge pipe, thereby floating on the water in the immersion part. There is an effect that can discharge the suspended matter intermittently to the discharge.
