Description

Detailed Description of the Invention

  The present invention relates to a method for producing a paper yarn in accordance with the use of a knitted fabric by giving false twist to a flat paper yarn obtained by chopping paper into a thin width.

  Flat paper thread that has been cut into narrow widths has problems in terms of thread shape, thread strength, etc., and in the same way as general thread, flat paper thread has a rounded shape for use in knitted fabrics. Therefore, it is necessary to increase the tear strength. Generally, it is twisted by a ring spinning machine, a double twister, an up twister or the like and used as a paper thread.

Problems to be solved by the invention

  In the conventional technique, the production amount does not increase because the twisting method of the paper yarn is an actual twisting method. Also, since the shape of the paper thread is flat, the twisting process is based on fluctuations in tension when passing through the thread guides and fluctuations in frictional resistance when the flat paper threads are pulled out from a package in which flat paper threads are wound in layers. Thread breakage frequently occurs in The present invention improves the working efficiency of the weaving and knitting process in the machine by improving the processing efficiency of flat paper yarn and preventing yarn breakage, lubricating the paper yarn after processing, improving the yarn strength, yarn shape and texture. This is a problem.

Means for solving the problem

  The purpose of applying a real twist to a flat paper thread that has been cut into a narrow width is that the flat paper thread that has been cut into a narrow width is composed of fine fibers aligned in the longitudinal direction. Although it has strength, when a slanting tension is applied to the longitudinal direction, it tears at both ends in the longitudinal direction and prevents the tear strength from drastically decreasing, and the flat paper thread has a rounded shape. This is to increase the tear strength.

  Applying a mixed solution of water and a water-soluble surfactant to a flat paper thread that has been cut into small widths without applying actual twist, the flat paper threads that have been cut into small widths are soft and moist. A flat paper thread that has been given a false twist in a state of chopping, and the paper is shredded into narrow widths by twisting unevenness is different from the case of leaving the S twist and Z twist, and at the same time applying a false twist to a general thread. The wrinkles in the longitudinal direction remain on the surface of the flat paper thread, resulting in a rounded shape.

  Furthermore, the wrinkles in the longitudinal direction remain on the surface of the flat paper yarn, and the rounded paper yarn is passed through a special yarn path guide with a V-shaped groove in the circumferential direction, thereby extending the length of the flat paper yarn on the surface. The wrinkles in the direction remain, and the rounded paper yarn is folded and crushed, and the paper yarn becomes further rounded and the tear strength increases.

Claim 1

According to the invention, when a flat paper thread that is cut into a thin width is pulled out from a package in which the flat paper thread that is cut into a thin and long width is wound in a laminated form, the flat paper thread that is cut into a thin width When the flat paper thread cut into a narrow width comes into contact with the laminated portions at the upper and lower ends of the package wound in a laminated shape, the winding shape is broken and the fall easily occurs. Also, when the flat paper thread chopped into a narrow width and the flat paper thread chopped into a narrow width are pulled out in contact with the surface of the package wound in a laminated form, If a flat paper thread that has been shredded on both sides of a thin paper thread and a flat paper thread that has been shredded in contact with the surface of a package that has been wound in a stacked manner, the difference in tension fluctuation is large, which can cause thread breakage. Become.

  A flat peg with long and narrow paper thread wound in a stack. A flat peg with a hollow peg at the center of the holder that holds the package. Attach a flyer that rotates with the pull-out tension of the paper thread. A flat paper thread that has been cut into small widths passes through a thread guide at the tip of the fryer and comes into contact with the surface of a package in which flat paper threads that have been cut into thin widths are wound in layers. Since it is pulled out without tension, fluctuations in tension are suppressed and thread breakage is prevented.

Claim 2

The purpose of this invention is to provide a tank of a mixed solution of water and a water-soluble surfactant for the purpose of facilitating twisting by making a flat paper thread obtained by chopping paper long and narrow into a soft and wet state. Install a motor-driven roller in the longitudinal direction of the provided container at a position where it comes into contact with the liquid surface of the mixed solution of water and a water-soluble surfactant. This is a device for applying a mixed solution of water and a water-soluble surfactant. When the liquid level of the mixed solution of water and water-soluble surfactant is lowered, the water and water-soluble surfactant are mixed in order to keep the amount of water and water-soluble surfactant mixed solution constant. The mixed solution of water and water-soluble surfactant is automatically replenished from the tank of the mixed solution of the surfactant. Further, by changing the rotation speed of the motor-driven roller, the amount of liquid applied to the flat paper thread obtained by cutting the paper of the mixed solution of water and water-soluble surfactant into a thin width can be adjusted.

Claim 3

The invention provides a feed roller that feeds a paper thread obtained by chopping paper into long and narrow widths while applying a mixed solution of water and a water-soluble surfactant while gripping it in a soft and wet state, and a mixture of water and a water-soluble surfactant. A false twist spindle for applying a twist to a soft and wet paper yarn by applying a solution, and a special yarn path with a V-shaped groove in the circumferential direction that folds the paper yarn to which the false twist is applied. A guide and a winding device for winding the guide around a package are installed along the paper yarn traveling direction.

  The feed roller that feeds out a soft and wet paper thread to which a mixed solution of water and water-soluble surfactant is applied consists of a weight-type top roller and a motor-driven bottom roller. On the surface of the roller, a groove having a width of 1 to 20 mm and a depth of 1 to 5 mm is inserted in the circumferential direction at a half of the circumference in order to periodically change the number of false twists from the false twist spindle.

  A soft and wet paper yarn to which a mixed solution of water and a water-soluble surfactant is applied is guided from a feed roller to a false twisting spindle and wound around a V-shaped yarn path guide attached to the lower exit of the false twisting spindle. Then, the false twist given by the rotation of the false twist spindle rises in the direction opposite to the traveling direction of the soft and wet paper yarn to which the mixed solution of water and water-soluble surfactant is applied, that is, toward the feeding roller. .

  The false twist that goes up toward the feeding roller is a portion of the weight-type top roller where there is no groove on the surface of the weight-type top roller with a soft and wet paper solution to which a mixed solution of water and water-soluble surfactant is applied. When it is gripped between the bottom rollers, it is stopped at the contact point between the weight type top roller and the motor-driven bottom roller. However, the gripping force between the motor-driven bottom rollers is released at the part where the groove of 1-20mm in width and 1-5mm in depth is put in the half of the circumference on the surface of the weight type top roller. The false twist that goes up toward the feed roller goes up further, so the false twist is compared with the false twist given between the part where there is no groove on the surface of the top roller and the bottom roller driven by the motor. There is a difference.

  The false twist spindle rotates at a constant speed, and the false twist is continuously given upward and the false twist is returned downward, starting from a V-shaped yarn path guide attached to the lower exit of the false twist spindle. Therefore, the false twist of the soft and wet paper yarn to which the mixed solution of water and water-soluble surfactant introduced to the false twist spindle is periodically changed between the grooved portion and the non-grooved portion of the top roller surface. However, the return of the false twist when passing through the V-shaped yarn path guide attached to the lower exit of the false twist spindle is constant. As a result, the twisted irregularity of the false twist occurs, and the paper yarn given the false twist in a soft and wet state to which a mixed solution of water and a water-soluble surfactant is applied is set to a period where the circumference of the feed roller is one cycle. A twisted portion, a non-twisted portion, and a Z-twisted portion are connected.

Unlike ordinary yarn, paper yarns with a shape in which the circumferential length of the feed roller is one cycle and the S-twisted part, non-twisted part, and Z-twisted part are connected to each other are wrinkled in the longitudinal direction on the surface of the paper thread due to false twisting. When the shape of the remaining paper thread is fixed, the paper thread is folded and crushed by further narrowing and passing through a V-shaped groove with a special thread guide that is provided in the circumferential direction, resulting in a rounded paper thread. Rolled up in a package.

Embodiment of the Invention

  A package 4 in which a flat paper thread 3 in which paper is cut into a thin width is wound around a paper tube 2 in a laminated form is mounted on a hollow peg 1 that is erected in the vertical direction. A fryer 6 is attached to an upper end portion of the hollow peg 1 via a fryer fixing pin 5. The flat paper thread 3 obtained by cutting the paper into thin widths passes through a thread guide 7 attached to the tip of the fryer 6 and the flat paper thread 3 obtained by cutting the paper into thin widths is wound in a laminated form. It is pulled out from the package 4.

  The position of the yarn path guide 7 attached to the tip of the flyer 6 is appropriate to be about 50 to 70 mm below the upper end of the package 4 in which the flat paper yarns 3 obtained by chopping the paper into small widths are wound in a laminated form. The fryer 6 is rotated by the pulling tension when the flat paper thread 3 obtained by cutting the existing paper into a thin width is pulled out from the package 4 wound in a laminated form.

  The flat paper thread 3 obtained by chopping the paper into a thin width passes through a yarn path guide 7 attached to the tip of a fryer 6 that rotates by pulling tension and is pulled out. The rotating fryer 6 adjusts the weight of the washer weight 8 sandwiched between the fryer 6 and the fryer fixing pin 5 so that the frictional resistance is generated, and the flat paper thread 3 chopped into thin paper is pulled out. Synchronize. As a result, the tension when the flat paper thread 3 cut into the thin width is pulled out from the package 4 wound in a laminated form is stabilized, so the flat paper thread 3 cut into the thin width is cut into the thin width. Winding breakage and twilling that occur when the flat paper yarn 3 comes into contact with the laminated portions 4A and 4B at the upper and lower ends of the package 4 wound in a laminated shape are suppressed. Further, when the surface of the flat paper thread 3 cut into a narrow width and the flat paper thread 3 cut into a thin width are brought into contact with the surface of the package 4 wound in a laminated form, and cut into a thin width. Yarn generated by fluctuations in tension when both sides of the flat paper yarn 3 cut and the flat paper yarn cut into a thin width come into contact with the surface of the package 4 wound in a stacked manner Prevent cutting.

  Since the main raw material of the flat paper thread 3 cut into small widths is made of manila hemp, the original characteristics of the paper thread 3 are hard and inflexible. Therefore, since it is easily cut in the fluctuation of the tension or the twisting process, the mixed paper 12 of water and a water-soluble surfactant is applied to the flat paper thread 3 that has been cut into a thin width, Passing while contacting the surface of the rotating roller 10 attached to a position in contact with the liquid surface of the mixed solution 12 of water and the water-soluble surfactant in the upward direction of the container 9 containing the mixed solution 12 of the water-soluble surfactant. Let

  A roller 10 attached to a position in contact with the liquid surface of the mixed solution 12 of water and a water-soluble surfactant is fixed to a drive shaft 11 driven by a motor, and the surface of the roller 10 is changed by a change in the rotational speed of the drive shaft 11. The liquid amount of the mixed solution 12 of water and a water-soluble surfactant applied to the flat paper thread 3 chopped into narrow widths while passing through can be adjusted.

  Further, in order to keep the liquid amount of the mixed solution 12 of water and water-soluble surfactant applied to the flat paper thread 3 chopped into a narrow width that passes while contacting the surface of the roller 10, When the water level of the mixed solution 12 of water and water-soluble surfactant falls, the mixed solution 12 of water and water-soluble surfactant is automatically supplied from the replenishing tank 13.

  The flat paper thread 3 chopped into a narrow width that passes while contacting the surface of the roller 10 is provided with a mixed solution 12 of water and a water-soluble surfactant to form a soft and wet paper thread 14 that is driven by a motor. Passing between a bottom roller 17 fixed to the shaft 16 and a weight-type top roller 15 having a groove with a width of 1 to 20 mm and a depth of 1 to 5 mm on the surface in half of the circumference in the circumferential direction, false twisting It is guided to the spindle 19 and wound around a V-shaped yarn path guide 20 attached to the lower exit of the false twist spindle 19.

  The flexible and wet paper yarn 14 is given a twist by the effect of the V-shaped yarn path guide 20 that rotates at the same speed as the false twist spindle 19, and the weight type top roller 15 and the weight type top roller 15 are rotated by the rotation of the bottom roller 17 and the weight type top roller 15. The operation of gripping or releasing with the presence or absence of a groove put on the surface of the roller 15 is repeated. By this operation, when the weight-type top roller 15 is gripped between the bottom roller 17 and the surface of the weight-type top roller 15, the false twist is stopped at the contact point of the weight-type top roller 15 and the bottom roller 17, but the weight method. When the surface of the top roller 15 is released between the grooved portion and the bottom roller 17, it passes between the weight type top roller 15 and the bottom roller 17, and the false twist further rises. As a result, the number of false twists between the bottom roller 17 and the weight type top roller 15 and between the false twist spindles 19 changes periodically.

  The V-shaped yarn path guide 20 in which the flexible and wet paper yarn 14 given the false twist is rotated at the same speed as the false twist spindle 19 by the effect of the V-shaped thread path guide 20 rotating at the same speed as the false twist spindle 19. The false twist is returned as many times as the false twist number given by the false twist spindle 19 when passing through, but the false twist number between the bottom roller 17 and the weight type top roller 15 and the false twist spindle 19 is periodic. As a result, twisting unevenness occurs, and as a result, the yarn 21 that has been softly and wetly provisionally twisted is connected to the S-twisted part, the non-twisted part, and the Z-twisted part with the circumference of the delivery roller as one cycle. The shape remains.

  The paper yarn 21 which has been given a soft twist in a soft and wet state is sent out by a special yarn path guide 23 which is provided with a V-shaped groove fixed to a drive shaft 22 which reciprocates between a certain distance by a cam drive. The length of the circumference of the roller is one cycle and the S-twisted part, untwisted part, and Z-twisted part are connected to each other, drawn into a crushed and crushed state, and driven by a motor as a rounded paper thread. Winding is performed on a package 25 attached to a winding device in which contact pressure is forcibly applied to a winding roller 24 fixed to the drive shaft 26.
