Description

  The present invention is a non-stretchable core yarn coated with a non-stretchable braid layer woven using a non-stretchable multifilament yarn and a monofilament bare yarn with a non-slip function. The present invention relates to a cored woven string, a shoelace and a wrapping string using the string, and a rescue / training string. Specifically, it is not used for shoelaces that are difficult to unravel while worn, packing straps that dislike unraveling when tied or bundled, or rescue / training straps that are relatively thin. The present invention relates to a stretch cored woven string.

  In the past, weaving yarn products that have been distributed as non-stretchable, i.e., non-stretchable, are actually somewhat stretched due to the nature of the fibers. However, this level of growth is currently ignored by consumers as natural growth or common sense growth. In view of such a current situation, the present invention also assumes that a material having natural elongation or common sense elongation has non-stretchability.

  Conventionally, this type of woven thread string has been widely used in various structures, but since it is suitable for facilitating understanding of the present invention, a shoelace will be described as an example here.

  In other words, most of the shoelaces in sports shoes, sneakers, walking shoes, business shoes and other shoes are only non-stretchable woven yarn that does not stretch (not using monofilament bare yarn with anti-slip function). It is woven (hereinafter referred to as the first conventional example in the text), inserted sequentially from the eyelet hole on the toe side, and tightened with a ribbon knot (bow) near the mouth or ankle, Therefore, it was used in the manner of fitting shoes to the feet.

  However, the shoelace tightening method according to the first conventional example has the following problems.

  First of all, the knot of the shoelace may loosen or unwind before you notice it while you are exercising or walking, and you must retighten or retie the shoelace each time. There was a problem such as being troublesome that it was necessary.

  Secondly, because I was walking without noticing that the shoelace had been unwound, there was often a risk that myself or another person would step on the loose end of the untied shoelace, and sometimes it would be unexpected There were problems such as leading to an accident.

  Thirdly, there is a problem that a sports contestant feels regretful that a shoelace is loosened or unraveled during the competition, causing a play mistake or lowering the rank without being interrupted. It was.

  Therefore, the present inventor has recently proposed a shoelace without a core material (hereinafter referred to as a second conventional example in the text) as disclosed in “Patent Document 1”. In this second conventional example, a monofilament bare yarn having a non-slip function is incorporated to eliminate the above-mentioned loosening and unraveling, so that an almost perfect effect can be obtained, and many praises have been obtained. Widely used. However, since the amount of growth that was previously ignored is slightly different for each product, it is also true that there are relatively many users who are not fully satisfied because the usage and tying of the users are not always constant. Met.

  Therefore, the inventor conducted research and development of a shoelace that was satisfactory to the above users. As a result, the present invention can be provided.

In addition, the present inventor, in the stage of research and development of the above shoelaces, if the manufacturing method is almost the same as the shoelaces, the packaging straps that dislike loosening or unraveling when tied or bundled It was decided by accident that it was possible to implement a string that produces a favorable result by using it for a rescue / training string having a relatively small thickness.
JP 2005-52614 A

  The present invention provides a novel non-stretchable cored woven yarn string that is not affected or hardly affected by the amount of elongation that has been ignored in the past, and a shoelace, packaging string, and rescue / training string using the same. Objective.

  In order to achieve the above object, the non-stretchable cored woven yarn string according to claim 1 uses a woven yarn made by combining a monofilament bare yarn having a non-slip function with a non-stretchable multifilament yarn. The woven braid layer is coated on the outer periphery of a non-stretchable core yarn aligned in parallel with the longitudinal direction.

  That is, the non-stretchable cored woven yarn string according to claim 1 has a non-stretchable multifilament thread and a non-stretchable layer in a non-stretchable braid layer when a knot such as a ribbon knot (bow) is formed in use. The core yarn functions to prevent the entire elongation, and the monofilament bare yarn exhibits an anti-slip function to eliminate loosening and unraveling of the knot.

  Further, in the non-stretchable cored woven yarn string according to claim 1, the core yarn is present in a linear state, and the non-stretchable multifilament yarn is present in a finished product in a meandering state. It will be. In other words, the amount of elongation previously neglected in the unit length of the finished product is extremely small corresponding to the shortened length of the linear and shorter core yarn, and the meander lengthens. It can be easily understood that there are many non-stretchable multifilament yarns. And the amount of elongation of the non-stretchable cored woven yarn string according to claim 1 that was previously ignored is structurally determined by the core material, not the amount of elongation of the braided layer that was previously ignored. .

  Therefore, with respect to the shoelace without a core material of the above-described conventional example 2 which has been determined by the non-stretchable multifilament yarn whose mean elongation has been meandered and lengthened, it has been ignored for the past. It can be seen that the non-stretchable cored woven yarn string according to the present invention in which the amount of elongation is determined by the core material is extremely reduced in structure.

  The non-stretchable cored woven yarn string according to claim 2 relates to the non-stretchable cored woven yarn string according to claim 1, wherein the monofilament bare yarn is scattered on the surface of a portion where a knot is formed during use. It is provided in an exposed state.

  The non-stretchable cored woven yarn string according to claim 3 relates to the non-stretchable cored woven yarn string according to claim 1 or 2, wherein the monofilament bare yarn is a bare yarn of synthetic rubber or raw rubber. It is what.

  A non-stretchable cored woven yarn string according to claim 4 relates to the non-stretchable cored woven yarn string according to claim 3, wherein the monofilament bare yarn is a polyurethane bare yarn. .

  A shoelace according to claim 5 is formed of a string portion by the non-stretchable cored woven yarn string according to any one of claims 1 to 4, and an end portion of the braid layer and a core at both ends of the string portion. An end fixing portion for mutual fixation of the end portions of the yarn is provided.

  A shoe according to claim 6 is provided with the shoelace according to claim 5.

  The packing string according to claim 7 is formed of a string part by the non-stretchable cored woven thread string according to any one of claims 1 to 4, and ends of the braid layer at both ends of the string part. The end part for mutual fixation of the end part of a core yarn is provided.

  A rescue / training cord according to claim 8 is formed of a cord portion by the non-stretchable cored woven yarn cord according to any one of claims 1 to 4, and ends of the braid layer at both ends of the cord portion. And an end portion for mutual fixation of the end portion of the core yarn and the core yarn.

  A non-stretchable cored woven yarn string according to claim 1 is a braided layer woven using a woven yarn made by combining a monofilament bare yarn having a non-slip function with a non-stretchable multifilament yarn, Since the outer periphery of the non-stretchable core yarn aligned in parallel with the longitudinal direction is coated, the non-stretchable core yarn is aligned in parallel with the longitudinal direction and is arranged on the outer periphery of the non-stretchable core yarn. It can be easily manufactured by a method of weaving a non-stretchable braid layer using a woven yarn made by combining a non-stretchable multifilament yarn and a monofilament bare yarn having a non-slip function.

  Further, in the non-stretchable cored woven yarn string according to claim 1, it is needless to say that the braided layer is not stretched or hardly stretched by the nonstretchable multifilament yarn and the nonstretchable core yarn. However, as described above, since the amount of elongation that has been ignored in the past is determined by the core material and is extremely small in structure, it has the advantage that it is not influenced by the amount of elongation that has been ignored in the past or is difficult to be performed. . Therefore, the intended purpose of providing a novel non-stretchable cored woven yarn string that is not influenced or hardly influenced by the amount of elongation that has been ignored in the past can be completely achieved.

  The non-stretchable cored woven yarn string according to claim 2 is provided in such a manner that the monofilament bare yarn is in a state of being exposed in a dotted arrangement on the surface of a portion where a knot is formed during use. It is possible to further enhance the function of preventing the state from being loosened or unwound.

  The non-stretchable cored woven yarn string according to claim 3 is characterized in that the monofilament bare yarn is a bare yarn of synthetic rubber or raw rubber, and can be easily and easily implemented at low cost.

  The non-stretchable cored woven yarn string according to claim 4 is characterized in that the bare yarn is polyurethane, so that it can be easily and easily implemented at low cost.

  A shoelace according to claim 5 is formed of a string portion by the non-stretchable cored woven yarn string according to any one of claims 1 to 4, and an end portion of the braid layer and a core at both ends of the string portion. Since it is characterized by the fact that the end of the thread is fixed at the end of the thread, it has the advantage that it does not loosen or unraveled during walking, or it is difficult to become loose, and the amount of elongation previously ignored. It is possible to provide a novel shoelace having an advantage that is not affected or hardly affected.

  Since the shoe according to claim 6 is provided with the shoelace according to claim 5, the advantage that the shoelace does not become loose or unraveled during walking or is difficult to be neglected and the above-mentioned neglect. It is possible to provide a novel shoe having an advantage which is not influenced or hardly influenced by the amount of stretch.

  The packing string according to claim 7 is formed of a string part by the non-stretchable cored woven thread string according to any one of claims 1 to 4, and ends of the braid layer at both ends of the string part. Since the end portion for fixing the core yarn ends is provided, it is not affected by the advantage that it does not become loose or unraveled during use, or is difficult to become, and the amount of elongation previously ignored or It is possible to provide a new packaging string that has the advantage that it is difficult to be loosened or unraveled.

  A rescue / training cord according to claim 8 is formed of a cord portion by the non-stretchable cored woven yarn cord according to any one of claims 1 to 4, and ends of the braid layer at both ends of the cord portion. Since the end of the core and the end of the core thread are provided with an end fixing part, it has the advantage of not loosening or unraveling during rescue / training, and the amount of elongation previously ignored. It is possible to provide a new rescue / training string that has the advantage of being unaffected or difficult to be loosened or unraveled.

  Hereinafter, embodiments of a non-stretchable cored woven yarn string according to the present invention will be described with reference to the drawings.

  First, FIGS. 1-3 shows the shoelace 1 in which the cross section which is one of the embodiments of the non-stretchable cored woven yarn string according to the present invention has a slightly flat shape.

  The shoelace 1 includes a string portion 2 and end members 3 and 4 attached to both ends of the string portion 2.

  The said string part 2 is manufactured as follows. That is, a large number of polyester core yarns 5 having non-stretchability are aligned and maintained in a tension state to form a core configuration portion 6 having a slightly flat cross-sectional shape and around the core configuration portion 6. , A large number of woven yarns incorporating non-stretchable polyester multifilament yarn 7 and polyurethane monofilament bare yarn 8 with anti-slip function with a stretch ratio of approximately 9 to 1. 9 is used to complete a long non-stretch woven yarn string (not shown) by providing the braid layer 10 and cut the completed long woven yarn string to a predetermined length. Yes.

  The core yarn 5 and the multifilament yarn 7 do not extend at all in nature and extend somewhat within a common sense range, but in the present application, they are provided with non-stretchability. Therefore, when the core yarn 5 and the multifilament yarn 7 are completed, a non-stretchable woven yarn string covered with the braided layer 10 having a non-stretch property is formed.

  Further, the end stop members 3 and 4 are provided at both end portions 12 of the cord portion 2 and firmly hold the end portion 13 of the braid layer 10 and the end portion 14 of the core yarn 5. In other words, the barbs can surely fulfill the function of fixing these end portions 13 and 14 together to prevent the unraveling and the function of facilitating the operation of inserting the shoe 16 into the eyelet hole 17 for threading. It is what is. In addition, it is free to carry out mutual fixation of these edge parts by adhesion | attachment, others, etc.

  When the shoelace 1 is attached to the shoe 16 (see FIG. 5), the polyurethane monofilament bare yarn 8 is pressed against the cut edge of the eyelet hole 17 to make it more difficult to loosen and unravel. It is.

  Further, as described above, the non-stretchable cored woven yarn string according to claim 1 is manufactured and processed while being maintained in a tension state where a large number of polyester core yarns having non-stretchability are maintained. Therefore, as a result, the core yarn 5 can be finished to a state in which the amount of elongation, which has been completed in a linear state and ignored in the past, is small.

  Next, FIGS. 6 to 8 show a thin rope 21 that can be used as a rescue / training cord having a round cross section, which is another embodiment of the cored woven yarn cord according to the present invention. It is shown.

  The rope 21 is manufactured as follows. That is, a large number of non-stretchable polyester core yarns 22 are aligned and maintained in a tensioned state, while forming a core component portion 23 having a round cross-sectional shape, around the core component portion 23, It is manufactured by providing a braid layer 24 using a large number of woven yarns 9 having the same configuration as that of the embodiment.

  Both ends of the rope 21 are fixed to each other by end stop members 27 and 28 that firmly hold the end 25 of the braid layer 24 and the end 26 of the core yarn 22. In other words, the ends 27 and 28 are prevented from being disengaged by the balance stop. In addition, it is free to carry out mutual fixation of these edge parts by adhesion | attachment, others, etc.

  Since the distribution of the number of the polyester multifilament yarn 7 and the polyurethane monofilament bare yarn 8 described above is determined by the properties of the material such as hardness and elongation, or the weaving method of the string, There is no need to be concerned with the above 9 to 1, and the braid layers 10 and 24 may be woven with a combination of a woven yarn 9 containing no polyurethane monofilament bare yarn 8 and a woven yarn 9 containing one or more. Needless to say, it can also be implemented by slightly increasing or decreasing the number. In short, it is important to moderately weave a satisfactory number of bare monofilament yarns 8 by performing an experiment or the like, and it should be loosened so that unraveling is hardly caused.

  It is more effective that the bare yarn 8 is woven in a convex shape on the outer surfaces of the braid layers 10 and 24. This convex weaving state can be easily implemented by pre-tangling the polyurethane monofilament bare yarn 8 with the polyester multifilament yarn 8 before the woven yarn 9 is constructed. This is effective not only because convex weaving portions (see many black dots indicated by reference numeral 29 in the figure) are formed on the outer surfaces of the braid layers 10 and 24, but also the thick monofilament bare yarn 8 By changing the height, the height of the convex weaving portion can be changed. That is, the strength of the anti-slip function can be easily provided by appropriately selecting and executing the number, thickness, and entanglement of the monofilament bare yarn 8.

  The non-stretchable cored woven yarn string according to the present invention can be implemented in a configuration that can be used for a shoulder string of clothing such as a brassiere, a camisole, and a slip. Moreover, it is preferable to use a deodorizing yarn having a deodorizing function for the yarn and core yarn constituting the braid layer. Further, it is optional to use cotton yarn or Tetron yarn as the core yarn. Furthermore, the non-stretchable cored woven yarn string according to the present invention can be diverted to a string used as apparel, care products, and other parts, and the present invention extends to this type of string.
