Description

  The present invention relates to a mop yarn that is a cleaning tool and a method for manufacturing the same.

In general, a mop yarn is produced by first producing a single twisted yarn using a spun yarn such as a plurality of cotton yarns or blended yarn as a raw yarn, and then twisting the plurality of single twisted yarns into a string form. Many yarns for mop are planted densely on the head of the mop, and the free end side is cut or curved in a loop. In such a mop yarn, in order to prevent the twist from returning and fraying during the use of the mop, a treatment for preventing fraying of the yarn tip is performed.
For example, Patent Document 1 proposes a technique in which the single twisted yarn is referred to as a strand, a plurality of the strands are arranged around a heat-sealing yarn, twisted together, and heated to prevent fraying.
Further, like Patent Document 2, this Patent Document 1 is improved, the single twisted yarn is referred to as a first twisted yarn, and the first twisted yarn itself is arranged around a heat-sealing yarn to be twisted and a plurality of twisted second twisted yarns. Furthermore, a technique has been proposed in which the second twisted yarn itself is arranged around the heat-sealing yarn to form a plurality of twisted mop yarns, which are heated to prevent fraying.

Japanese Patent No. 3038102 Japanese Patent No. 4464257

Although the mop yarn of Patent Literature 1 prevents fraying, as described in Patent Literature 2, the mop yarn of Patent Literature 1 is not sufficient in function. However, the mop yarn of Patent Document 2 is also described in Patent Document 1 as a first step for producing a first twisted yarn as a process, a second step for producing a second twisted yarn, and a third step for producing a twisted yarn for mop. It is hard to say that fraying of the yarn tip is sufficiently prevented in spite of having many processes.
Therefore, there has been a demand for a mop yarn that is sufficiently prevented from fraying of the yarn tip and has a generally better mop yarn strength, dust capturing ability, holding power, and the like, and a method for manufacturing the same.

In order to achieve the above object, as means 1, in a method for manufacturing a mop yarn, a plurality of first bobbins obtained by winding a raw yarn around a bobbin outer periphery, and a first heat fusion yarn around the bobbin outer periphery A first step of producing a first aggregated yarn by drawing out the yarns from one or a plurality of second spools that are wound to combine them, and a plurality of the first aggregated yarns and one or more of the first aggregated yarns A second step of producing a second aggregated yarn by twisting the second heat-fusible yarn, and a first step of heating the first heat-fusible yarn and the second heat-fusible yarn by heating means. 3 steps.
As a result, when the yarns are pulled out from the first bobbin body and the second bobbin body in the first step to be combined, they are pulled out around the bobbin so that each thread is pulled out in parallel. Instead (that is, there is no superiority of arrangement in a specific yarn), they are mixed together while swaying and are randomly drawn and combined. That is, the plurality of raw yarns are intertwined with each other, and at the same time, the first heat-fusible yarn is intertwined with the raw yarns inside and outside to form a composite yarn. Since the yarns are randomly arranged in this way, the first heat-sealing yarn is melted by being heated in the third step, and is fused at a position where it intersects and contacts the surrounding raw yarn. It will be. As a result, the raw yarns are gently joined through the first heat-sealing yarn at the stage of the first aggregate yarn.
The plurality of first aggregate yarns are twisted together with the second heat fusion yarn in the second step, and the second heat fusion yarn is interposed between the plurality of first aggregate yarns. The second heat-bonded yarn is melted by being heated in the third step, and the first aggregate yarns are fused together. Therefore, in the second aggregate yarn, the first aggregate yarns are There is no separation.
In the case of a mop yarn manufactured in this way, fraying of the yarn tip is very little. Further, since the original yarns are fixed to each other by the first heat-sealing yarn at the stage of the first collecting yarn, the strength of the yarn is improved as compared with the case where such a configuration is not adopted. On the other hand, although the strength is improved, since the raw yarns are only joined together in part, the flexibility is not impaired. Moreover, since the yarns of the first aggregate yarn are fixed at random, and the portion for securing dust increases when used as a mop, the dust holding power is improved.

Here, since the “raw yarn” is for mop, it must have good water absorbency and dust adsorbability, so it is, for example, cotton yarn or blended yarn obtained by spinning short fibers generally called “single yarn”. Is good.
The "first (or second) bobbin" is not particularly limited in shape, for example, a flat cylindrical bobbin called a so-called cheese, or a conical shape called a so-called cone with a sunk upper part. A pincushion or the like.
The “first (or second) heat-sealed yarn” is, for example, a filament-like yarn made of a synthetic fiber exhibiting thermoplasticity, and may be melted at a temperature of 80 to 165 ° C. For example, low melting point nylon, polyethylene, polyester, polyamide and the like are preferable.
The “first aggregate yarn” is a yarn obtained by combining a plurality of original yarns and one or a plurality of first heat-sealing yarns, and may be twisted or not twisted. When twisted together, the “aggregate yarn” becomes a “twisted yarn”.
The “second aggregate yarn” is a yarn obtained by combining a plurality of first aggregate yarns and one or a plurality of second heat fusion yarns, and is formed as a twisted yarn by twisting them together.
In the present invention, the production of “mop yarn” has the first to third steps as described above, but is not limited to “consisting only of the first to third steps”. Therefore, the claims are not claimed to deny the possibility that additional steps will be added to produce mop yarn. For example, after the second aggregate yarn is manufactured, a plurality of second aggregate yarns are further twisted to form a mop yarn, which can be understood as having the first to third steps. . The same applies to a case where a mop yarn produced by the first to third steps is subjected to some physical / chemical treatment.
The “heating means” is, for example, a kettle or a boiler.

Further, as the means 2, the first heat fusion yarn and the second heat fusion yarn are heated simultaneously.
Thus, the heating process is not performed separately, the manufacturing time of the mop yarn is shortened, and the manufacturing cost is also reduced. As the reverse of the means 2, the present invention also assumes that the first heat fusion yarn and the second heat fusion yarn are heated separately.
Further, as the means 3, in the second step, one of the first collective yarns contacts the other one of the first collective yarns in the longitudinal direction of the yarn via the second heat fusion yarn. It was made to twist together.
As a twisting method, it is preferable that one first collective yarn always comes into contact with the other first first collective yarn in the longitudinal direction of the yarn via the second heat-sealed yarn. This is because the second aggregate yarn is not separated into the first aggregate yarn which is a unit constituting the second aggregate yarn, and as a result, fraying of the yarn tip is prevented.
For example, as shown in FIG. 5 (a), when there are two or more first aggregate yarns, one second heat-sealing yarn is preferably arranged in the middle of them and twisted together. As a result, the second heat-sealing yarn is disposed along the longitudinal direction between the two first aggregate yarns, and the two first aggregate yarns are not frayed. In addition, in the case of using three second first fusing yarns and one second fusing yarn, the first collecting yarn is arranged at the apex position of the triangle as shown in FIG. The second heat-sealing yarn may be arranged and twisted inside the three first aggregate yarns. That is, when one second heat-sealing yarn is used for the plurality of first aggregate yarns, the one second heat-sealing yarn is located at an approximately equal position from the plurality of first aggregate yarns. It is good to arrange | position to the inside enclosed by these some 1st aggregate yarns.
On the other hand, when the first aggregate yarn is three and two second heat-sealing yarns are used, they may be arranged in parallel as shown in FIG. 5C, for example. That is, when a plurality of second heat-bonding yarns are used with a plurality of first aggregate yarns, the first heat-bonding yarns need not be surrounded by the plurality of first aggregate yarns. This is because the aggregate yarn can be twisted so as to come into contact with the other first aggregate yarn in the longitudinal direction of the yarn via the second heat-sealing yarn.

Further, as means 4, the first aggregate yarn is twisted after being combined.
Thus, by using the first aggregate yarn as the twisted yarn, the first aggregate yarn is gathered, and the portion to be fused by the first heat-sealed yarn of the original yarn is increased. In addition, the yarn strength is improved by twisting.
Further, as the means 5, the first aggregate yarn is twisted at a twist number of 200 T / m or less.
This number of twists belongs to the so-called sweet twist. When the number of twists is kept at this level, the yarn is not strongly tightened, and when the original yarn is fused by the first heat-fusible yarn, it becomes a suitable fusion state due to a cross-linked state or a gap between yarns. It is possible to favorably maintain dust trapping and holding power, water holding power when applied to water, and the like. The twist number is more preferably 80 to 100 T / m. In addition, although it is suitable to twist the 1st aggregate yarn with the twist number of 200 T / m or less, in this invention, twisting with the other twist number is also assumed.

Further, as the means 6, when the second aggregate yarn is manufactured, it is twisted in the direction opposite to the twist direction of the first aggregate yarn.
As a result, the first aggregate yarn and various twists are performed. As a result, the adhesion between the plurality of first aggregate yarns is improved, and as a result, the adhesion with the second heat fusion yarn is also improved, so that the plurality of first aggregate yarns are firmly fused. It becomes.
Moreover, as the means 7, the thickness of the raw yarn was 5-15.
This is because when the raw yarn fits in such a thickness, it is easy to make a yarn having a thickness suitable as a mop yarn when the process proceeds, such as the first aggregate yarn and the second aggregate yarn thereafter. .
Further, as means 8, the thickness of the first heat-sealing yarn was 30 to 170 denier (D).
This is because, when the first heat-sealed yarn falls within such a thickness, it is easy to make a yarn having a thickness suitable as a mop yarn when the process proceeds, such as a subsequent second aggregate yarn.

Further, as the means 9, in the mop yarn, one or a plurality of first heat fusion yarns and a plurality of raw yarns are complicated with each other, and the first heat fusion yarns are a plurality of the original yarns. The first aggregate yarn is constituted by heat fusion at the crossing and contacting position, and the plurality of first aggregate yarns and one or the plurality of second heat fusion yarns are twisted together in the longitudinal direction of the yarn. A plurality of the first collective yarns are heat-sealed through the second heat fusion yarns to form a second collective yarn.
This is a description of a mop yarn manufactured by means 1 from the viewpoint of the invention of “thing”.
With the mop yarn having such a configuration, fraying of the yarn tip is extremely reduced. Further, since the original yarns are fixed to each other by the first heat-sealing yarn at the stage of the first collecting yarn, the strength of the yarn is improved as compared with the case where such a configuration is not adopted. On the other hand, although the strength is improved, since the raw yarns are only joined together in part, the flexibility is not impaired. Moreover, since the yarns of the first aggregate yarn are fixed at random, and the portion for securing the dust increases when used as a mop, dust trapping and holding power are improved.

  According to the present invention, it is possible to provide a yarn for a mop that is hard to fray and has high dust trapping ability and holding power.

Hereinafter, a method for manufacturing a mop yarn and a mop yarn according to an embodiment of the present invention will be described with reference to the drawings.
In the present embodiment, as a method for producing a mop yarn, a first step of producing a first twisted yarn from a single yarn, a second step of producing a second twisted yarn from the first twisted yarn, and a third heating step The mop yarn is manufactured through these steps. Hereinafter, each process will be described.
(1) First Step As shown in FIG. 1, in the present embodiment, first, six first cheeses 1 and one second cheese 2 are prepared and installed on a horizontal plane. The first cheese 1 is a bobbin in which a single yarn 3 spun from cotton yarn or mixed yarn as a raw material is wound around a bobbin 4. The second cheese 2 is a bobbin in which a first heat-sealing yarn 5 made of a low melting point nylon monofilament is wound around a bobbin 4. The thickness of the single yarn 3 is not particularly limited, but it is preferably 5 to 15 and the 10th is used in this embodiment. The thickness of the first heat-fusible yarn 5 is not particularly limited, but is preferably 30 to 170 denier (D), and 100D is used in the present embodiment.

As shown in FIG. 1, the single yarn 3 and the first heat fusion yarn 5 are pulled out from the six first cheeses 1 and one second cheese 2 respectively, and passed through a ring-shaped threader 7. By pulling them together, the combined yarn 8 is brought into a state. The combined yarn 8 is wound around a bobbin set on a well-known twisting machine (not shown) while passing through a yarn path (not shown).
As shown in FIG. 2, when the single yarn 3 or the first heat fusion yarn 5 is launched from the first or second cheese 1, 2, the single yarn 3 or the first heat fusion yarn 5 is formed on the bobbin 4. It will be aligned while rotating around (ie, changing position). Therefore, as shown in FIG. 3A, in the state of the combined yarn 8, there is no superiority or inferior arrangement, and the single yarn 3 and the first heat fusion yarn 5 are combined with each other in a complicated manner. The single yarn 3 and the first heat-sealing yarn 5 that are combined yarn 8 are twisted in a single-twist manner by Z-twisting as shown in FIG. The twisting of the first twisted yarn 9 is preferably about 80 to 100 T / m, and in this embodiment, it is set to 80 T / m. This is because the number of twists is such that the first twisted yarn 9 is not strongly tightened and dust is easily retained.
The first twisted yarn 9 configured in this manner is in a state where the first heat-sealing yarn 5 intersects and contacts the single yarn 3 at some points as shown in FIG. In the present embodiment, the first twisted yarn 9 is configured to have a thickness of about 1.5. The first twisted yarn 9 is wound around a bobbin (not shown) to form a cone-shaped bobbin. In FIGS. 3 (a) and 3 (b), the heat-sealing yarn 5 is represented by a solid color for the sake of easy understanding, but is actually composed of the same color as the single yarn 3 (for example, white). At first glance, the heat-sealed yarn 5 is not clearly visible in the yarn 8 state.

(2) Second Step In the second step, from two cones (not shown) wound with the first twisted yarn 9 and cheese (not shown) wound with the second heat fusion yarn 10 made of a low melting point nylon monofilament. The two first twisted yarns 9 and the second heat fusion yarn 10 are drawn together and twisted by a well-known twisting machine (not shown). The thickness of the second heat fusion yarn 10 is preferably about 170 to 500D, and 200D is used in the present embodiment. As shown in FIG. 4, in the present embodiment, the second heat-sealing yarn 10 is disposed between the two first twisted yarns 9 and S twisted (that is, the direction of the first twisted yarn 9 is applied) Are twisted in the opposite direction to form the second twisted yarn 11. The number of twists of the second twisted yarn 11 in the twisting is slightly larger than the number of twists of the first twisted yarn 9, and the twisting is preferably performed at about 145 to 165 T / m. In this embodiment, 150 T / m and did.
The second twisted yarn 11 thus configured is arranged with the second heat-sealed yarn 10 in close contact between the first twisted yarns 9 as shown in FIG. In the present embodiment, the second twisted yarn 11 has a thickness of about 0.8. The second twisted yarn 11 is wound around a bobbin (not shown) to form a cone-shaped bobbin. In FIG. 4, the heat-sealing yarn 10 is expressed by being painted for easy understanding, but actually, the heat-sealing yarn 10 is not clearly visible at a glance as in the above.
(3) 3rd process The 2nd twisted yarn 11 of a cone state or a cocoon state is accommodated in the well-known boiler which is not shown in a heating means, and the 1st heat-fusion yarn 5 and the 2nd heat-fusion yarn 10 are It heats at the temperature which melt | dissolves, for example, the temperature range of 80-150 degreeC, It is made to cool after that. Thereby, the single yarn 3 is mainly crosslinked by the first heat-sealing yarn 5, and the second twisted yarn 11 in which the first twisted yarn 9 is mainly in close contact with the second heat-sealing yarn 10 can be obtained. Here, “mainly” means that, for example, the melted first heat-sealed yarn 5 on one first twisted yarn 9 side is fused with the single yarn 3 on the other first twisted yarn 9 side, This is because there are cases where the first heat-sealing yarn 5 and the second heat-sealing yarn 10 are fused.
The second twisted yarn 11 is appropriately cut to obtain a mop yarn.

With this configuration, the present embodiment has the following effects.
(1) Since the first heat fusion yarn 5 joins the single yarns 3 together, and the second heat fusion yarn 10 joins the first twist yarns 9 together, the twist of the second twist yarn 11 is returned. Further, the twist of the first twisted yarn 9 constituting the second twisted yarn 11 is also difficult to return.
(2) At the same time as the fraying becomes difficult, the first twisted yarns 9 are only loosely coupled to each other by the first heat-sealing yarns 5, and as a result, they are less frayed and dust trapping and holding power In addition, the water retention capacity when further immersed in water is improved.
(3) The first heat fusion yarn 5 is preferably thinner than the second heat fusion yarn 10. This is because the thinner one holds the single yarn 3 supple. On the other hand, the second heat fusion yarn 10 is thick because the first twisted yarns 9 are firmly adhered in the longitudinal direction.

The above embodiments are merely described as specific embodiments for illustrating the principle of the present invention and the concept thereof. That is, the present invention is not limited to the above embodiment. The present invention can also be embodied in the following modified form, for example.
In the above embodiment, the first twisted yarn 9 is loosely twisted, but it is not necessary to twist. This is because the first heat-fusible yarn 5 binds the single yarns 3 to each other without twisting, and is difficult to fray.
In the above description, the first twisted yarn 9 is constituted by Z twist and the second twisted yarn 11 is constituted by S twist, but this twisting method may be reversed.
-You may heat with heating means other than the above. Moreover, you may heat in the state of the 1st twisted yarn 9. FIG.
The first heat-sealing yarn 5 and the second heat-sealing yarn 10 may be yarns other than the low-melting point nylon monofilament, such as polyamide-based low-melting point filaments. Different types of yarn may be used for the first heat-sealing yarn 5 and the second heat-sealing yarn 10. In addition, as described above, the second heat-sealing yarn 10 may be thicker than the first heat-sealing yarn 5, but may have the same thickness or may be thinner.
The present invention is not limited to the configuration described in the above embodiment. The components of the above-described embodiments and modifications may be arbitrarily selected and combined. In addition, any component of each embodiment or modification, and any component described in the means for solving the invention or any component described in the means for solving the invention And may be combined arbitrarily.
