Description

Description: TECHNICAL FIELD The present invention relates to a braid, and more particularly, to a round braid that can be used in various ropes or slings.

[Prior art] Conventionally, as a fiber product having a substantially round cross section, it has a structure of a round braid made using a lacing machine, a twisted rope represented by a so-called three-stroke rope, a braid. There are braided ropes.

Among them, twisted ropes and braided ropes include ropes for pole safety belts, slings, ropes, various types of lead ropes, fishing nets and ropes, and ships and maritime ropes. It is used in many fields.

However, conventional ropes of this type cannot be easily applied using sewing means or the like in order to connect the ropes or to fit other parts together. The terminal processing called "was not possible without manual work." This processing requires skilled labor and takes a long time to process, so that it is unavoidable that the cost increases.

Further, in this kind of rope, a rigid structure has to be used in terms of abrasion and durability, so that a soft rope cannot be supplied except when these properties can be neglected.

On the other hand, rounded braids, which are mainly relatively thin and soft, have limited applications because of their structure, they could not only sew, but could not even process such as eye processing in the foreground, and mainly had to rely on bundling. It had been.

The use of a belt made of a narrow-width fabric for applications similar to ropes and braids has also been partially adopted, but such belts have been used only for special applications. Because, when compared to ropes, narrow woven fabrics are not only difficult to grasp by hand, but also cause twisting during use, for example, when used for ropes of ropes or safety belts on poles. This is due to inconveniences such as danger in use due to rocking in the wind.

In other words, in the past, these twisted and braided ropes,
The round braid and the narrow woven fabric are different products in terms of structure and use, and each has its own advantages and disadvantages. Under these circumstances, in relation to the application, while maintaining a soft texture while having a round cross-section like a rope,
It has been considered that a product that can easily perform the terminal, such as a means for sewing belts, is desired but not possible.

[Problems to be solved by the invention]

The present invention improves on the drawbacks of the prior art as described above, and has a structure in which a terminal can be machined by sewing means while maintaining a soft texture while having a round cross section like a rope. It is intended to provide a thin and narrow fabric.

[Means for solving the problem]

The present invention basically employs the following technical structure to achieve the above object.

That is, the narrow cloth according to the present invention is characterized in that a part of the main body is covered with the braid, and at least one end of the main body is exposed from an end of the braid.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In each of the accompanying drawings, only the main part is schematically shown.

The braid used in the narrow fabric according to the present invention,
It is the same as a round braid that has been generally used in the past,
For example, a braid is used as a braid using a 16-stroke, 24-stroke, 48-stroke or the like.

However, in the present invention, ordinary conditions can be adopted for the conditions such as the number of beats constituting the braid, the type of the fiber yarn constituting the braid, the fineness, the number of aligned yarns, the presence or absence of twist, the braid density, and the like. However, it is not manufactured under any particular conditions.

Such conditions need to be determined according to the required use of the braid.

On the other hand, in the narrow cloth according to the present invention, a part of the narrow cloth is covered with a braid-shaped member constituted by a braided structure, and the narrow cloth portion covered with the braid-shaped portion is provided. Is formed so as to be substantially circular, and furthermore, a part of the narrow cloth not covered with the braided member is configured to be subjected to a predetermined processing as an end of the rope. is there.

In the present invention, the strength of the braid is substantially that of the narrow fabric, and the braid forming the outside of the braid does not directly contribute to the strength of the braid, but rather. And an effect for rounding the shape of the protective material of the narrow cloth or the braid itself.

In addition, as the narrow cloth, as described above, the terminal processing for connecting the ends or attaching accessories such as metal fittings can be processed by sewing means without depending on so-called satsuma processing. It is provided in order to make a simple structure.

Needless to say, the narrow cloth in the present invention preferably has a structure that is easily bent or curved in the width direction of the narrow cloth so as not to impair the roundness and soft feel of the braid.

At the time of manufacturing the braid, a suitable supply means such as a jig having a curved guide is provided at the center of a bobbin group arranged in an annular shape at the time of manufacturing the braid. And completed at the same time.

As the narrow fabric of the present invention, any fabric such as a woven fabric, a knitted fabric or a non-woven fabric can be used, but the use of a narrow fabric is particularly preferred.

The narrow woven fabric may be a narrow woven fabric woven by a dedicated loom from the beginning, or a narrow woven fabric obtained by appropriately cutting a wide woven fabric.

Further, there is no particular limitation on the fiber material used for the narrow fabric, and a known fiber material such as nylon, polyester, polyacryl, polyethylene, polyvinyl chloride, etc. can be used. The fineness, density (number of fibers), woven structure, etc. are not particularly limited, and can be freely designed and used according to the application.

In the present invention, the narrow fabric is disposed at the center as a core material of the braid and is not exposed to the outside, so that it has problems such as appearance texture, dyeing, light resistance, and friction resistance. It is not necessary to take into account the fact that any material that satisfies substantial performance such as strength and elongation can be used.

For example, an "aramid" fiber has a problem in light resistance, abrasion resistance and the like, and cannot be generally used in a bare state. Can be manufactured.

Next, the narrow fabric according to the present invention has a structure that is easily bent or bent in the width direction as described above, and the structure itself is not particularly specified. Any structure may be used as long as the external shape of the braid is cylindrical when the structure is adopted so that the external appearance of the braid can be easily formed in the round braid.

For this purpose, the narrow fabric may be formed in a curved shape from the beginning, or may be easily bent or curved into a tubular shape by the jig as described above. Is also good.

Further, depending on the case, it may be a tubular shape due to the tension of the braid of the braid.

The following are conceivable as specific examples of the structure of the narrow fabric.

(1) As shown in FIG. 3 (a), a woven fabric structure in which the density of yarns (the number of yarns per unit) on one surface of the narrow woven fabric is higher than the density on the other surface is adopted.

For example, when weaving with a twill weave design of 3/1 using 136 warps of full width, 102 threads, 3/4 of the warp, are woven on one side, and 34 threads, 1/4, are opposite each time weft driving is performed. Woven into the surface. Accordingly, as shown in FIG. 3 (b), the narrow fabric has a structure in which the number of the narrow fabrics is small and the tubular fabric is easily curved in a cylindrical shape around the woven surface.

(2) Next, as shown in FIG. 4 (a), the narrow woven fabric has a double woven structure, and the density of the yarns on one surface is extremely higher than the density of the woven structure on the other surface. It is also possible to use those that have been increased.

For example, 3/4 of the full-diameter yarn is arranged on the surface texture and the density of the yarn is 169 yarns / full width, and the remaining 1/4 diameter yarn is arranged on the back surface and the density of the yarn is 56 yarns / It is the full width. With this structure, the same effect as described above can be obtained.

(3) In addition, as shown in FIG. 5 (a), a woven structure in which the thickness of the woven fabric is varied in the width direction of the narrow woven fabric is introduced, and the narrow woven fabric is bent at the thin portion. It may be configured.

In the structure, the thick portion A may have a 1/1 double plain weave structure, for example, and the thin portion B may have a 1/1 single plain weave structure.

Further, an appropriate core material C may be inserted into the thick portion A of the woven structure, whereby a core material having a constant diameter can be formed.

For example, the density of the surface diameter yarn with a flat double weave
This yarn has a density of 22 yarns, 30 yarns of the same diameter as the core yarn, and a yarn density of 20 yarns in the plain single weave structure of the B portion. Can be used.

As shown in FIG. 5 (b), the core material having such a structure is a core material similar to a triple twisted rope.

(4) Even a narrow woven fabric having a normal woven structure can be easily bent by partially changing the diameter and the material of the diameter yarn.

For example, as shown in FIG. 6 (a), a fine yarn may be used for a part of the diameter yarn A and a fine yarn may be used for another part of the diameter yarn B. .

In the narrow woven fabric having such a structure, a core material bent in a wavy shape as shown in FIG. 6B is obtained.

(5) Regardless of the weaving structure, it is also possible to make the narrow-width woven fabric easy to bend by applying a twist in the same direction to the diameter yarn. If necessary, this can be used alone or in combination with any of the above structures. The twisting of the diameter yarn can be introduced.

Since the narrow fabric in the present invention imparts the strength in the longitudinal direction of the braid, it is sufficient that the narrow fabric also has a greater strength with the diameter yarn, and therefore the density of the weft is not so high. Is also good.

The width of the narrow woven fabric of the present invention is not particularly limited, but may have an appropriate width corresponding to a braid having a thickness corresponding to the intended use.

Generally, an object of about 10 mm to 100 mm is used.

In the present invention, it is preferable to increase the width and reduce the volume of the narrow fabric, since the strength with respect to the weight is improved, and there is also an effect that the cost is reduced.

In the present invention, the characteristics of the braid can be freely changed by giving the core material a variety.

In other words, although the braid of the braid has no particular strength, the core material covers it, so the thickness and strength of the braid do not require almost severe conditions, but the number of twists, dyeability, light resistance The choice is based on gender and other factors.

In the narrow cloth according to the present invention, the form of the narrow cloth in the braid may be a hollow pipe-shaped cross section, or a spiral swirl. They may be present, or may be folded in a wave shape.

Conventionally, there has been an attempt to insert the core material into a braided rope or braid. However, even if the yarn is inserted independently, the yarn is still loosely inserted, so there is strong variation, and the strong utilization rate is low. Not only is it low, but the outside is easy to stretch and the core side is difficult to stretch, so there is a drawback that the core is easy to cut first.

However, in the present invention, since the core material is inserted into the braid in the form of a woven fabric, there is no variation in the strength, and the utilization rate of the strong material is high, and there is no displacement between the braid portion and the narrow woven fabric portion. A difficult braid can be obtained.

Conventionally, generally used polyester ropes are not as strong as generally believed, as shown in the JIS standard, and narrow-width fabrics are much stronger at the same mass.

In the present invention, the shape, structure, etc. of the outer braid portion may need to be changed depending on the application, and in that case, the material of the braid can be changed as appropriate.

For example, when a thin and tight braid is required, a thin and tight braid can be obtained by manufacturing a braid using a highly contractile yarn as the braid used for the braid and then contracting the braid. In this case, a narrow cloth may be used as the core material, but it may be one in which a plurality of yarns are simply inserted.

Such a shrinkable yarn may be a heat-shrinkable fiber or a fiber that can shrink with moisture.

In the latter case, vinylon-based fibers having high shrinkage under humidity, for example, "Sorblon" fibers can be used.

Specifically, in the braiding step, the outside of the braid is braided with the vinylon-based yarn, and the braid is shrunk by containing moisture to stabilize the shape of the braid.

If it is preferable to make the whole braid soft, or if it is desired to make it harder, it can be changed by adjusting the amount of use and the processing conditions.

In that case, the shrinkable yarn and the non-shrinkable yarn can be mixed and adjusted at an appropriate ratio.

As another example, a fiber that is resistant to abrasion and environmental changes can be used as the braid thread.

In the present invention, the braid having a rigid structure obtained by shrinking the braid can be used, for example, as a buckle support for a seat belt of an automobile in which a conventional wire rope has been used.

〔Example〕

Hereinafter, specific examples of the narrow cloth according to the present invention will be described in the form of examples.

Example 1 Weaving organization 3/1 single-flow twill weave Aramid fiber 1500d-1000f / 1 136 weft Aramid fiber 1000d-666f / 1,20pics / 30m 32mm width narrow fabric with the above specifications using a needle loom Weaved.

Since the narrow fabric has a woven structure of 3/1, the density is high because 3/4 of the diameter yarn is arranged on the surface of the narrow fabric and 1/4 of the diameter yarn is arranged on the back surface. Is low.

Therefore, the high-density fabric tends to spread in the width direction, and the low-density back surface has a gap between the yarns and is easily shrunk, so that the narrow fabric naturally curves in the width direction.

In addition, since the yarn was twisted, the narrow fabric was twisted in the longitudinal direction and rounded in a natural shape.

 Using this narrow fabric as a core material, a 24-strand braided braid was manufactured using polyester 1000-96f / 1 // 2 as the braid.

The narrow fabric did not use any jigs, but was naturally incorporated in a round shape, and the appearance became a normal 8 mm diameter round braid.

As a result of a tensile test using a tensile tester, the breaking strength was 3300 kg and the elongation at break was 3.6%.

For reference, the standard value of the tensile strength of 8mm rope (linear density 49.4g / m) in JIS L2707 "Polyester rope"
It is 960kgf.

When the end of the round braid was opened and the ring was sewn, a tensile test showed a breaking strength of 2700 kgf.

Example 2 Woven structure 1/1 flat double weave Diameter Yarn Surface yarn polyester 1500d-108f // 1 169 Lining yarn polyester 1500d-108f // 1 56 Yarn binding polyester 1500d-108f // 1 13 Weft polyester Between 1500d-96f // 1,24pics / 30m A narrow woven fabric with a width of 45mm was woven with the above specifications using a needle loom.

The surface yarn of the ground yarn has about three times the number of diameter yarns woven into the back surface.

For this reason, as in the case of Example 1, the diameter yarn is about to spread on the front surface in the width direction and the back surface is easily shrunk, so that the narrow fabric naturally curves in the flap direction.

 The binding yarn is a yarn that binds the woven structure of the front surface and the back surface.

 Using this narrow fabric as a core material, a 48-strand braided braid was manufactured using polyester 1000-96f / 1 as a braid.

When feeding the narrow fabric, a jig having a shape in which the funnel was turned upside down was used to make sure that the narrow fabric was incorporated in a round shape.

The appearance of the braid incorporating the narrow fabric is an ordinary 10
It became a round braid with a diameter of mm.

As a result of a tensile test using a tensile tester,
The breaking strength was 2500 kg and the breaking elongation was 35%.

1 in JIS L2707 "Polyester rope" for reference
The standard value of the tensile strength of 0mm rope (linear density 77.0g / m) is 15
It is 90kgf.

When the end of the round braid was opened and the ring was sewn, a tensile test showed that the breaking strength was 1880 kgf.

Example 3 Weaving structure 1/1 plain double weave + 1/1 plain weave Diameter Double weave partial ground yarn Polypropylene 680d-120f // 1 133 double weave partial core yarn Polypropylene 680d-120f // 3 30 plain weave Ground yarn Polypropylene 680d-120f // 1 40 wefts Polypropylene 680d-120f // 1,20pics / 30m A narrow woven fabric with a width of 25mm was woven with the above specifications using a needle loom.

The double weave portion and the plain weave portion have a width of about 5 mm in the width direction, and three and two stripes are alternately arranged.

The double woven portion is woven so that the core yarn is woven to have a volume in it, and the thickness is increased.

Further, since the plain woven portion sandwiched between the double woven portions has a small thickness, the narrow woven fabric is easily bent and rounded in the plain woven portion, or easily bent in a waveform.

 Using this narrow fabric as the core material, a 24-strand braided braid was manufactured using polypropylene 680d-120f // 2 as the braid.

The appearance of the braid incorporating the narrow fabric is an ordinary 5m
It became a round braid of m diameter.

When manufacturing a normal round perforated braid, it is common practice to form a round perforated braid for a core in advance and insert several of these into the core.

In the case of the present embodiment, this case corresponds to a case in which three cores are inserted, and the same effect can be produced efficiently and inexpensively.

Since the round braid of the present invention has the structure as described above, the material, thickness, density, presence or absence of twist, degree of twist, weave structure, etc. of the yarn used for the narrow fabric used as the core material are used. The thickness, width, and shape can be freely determined by combining various types of, so that it can be designed and manufactured according to the demands of applications, etc., so that the field of use of conventional ropes and braids will be greatly expanded Can be done.

That is, in the present invention, by combining the narrow fabric and the braid, it is possible to make up for the disadvantages of each and utilize the advantages.

Needless to say, in the present invention, since the belt is mainly composed of round braids, it is easy to grasp by hand even when compared with a conventional belt, can be used without worrying about twisting, and flickers even in the wind. This makes it possible to manufacture a rope-shaped product that is convenient for use and that can be manufactured at relatively low cost.

Further, while the conventional braid could not cope with the required characteristics in detail, the present invention can freely produce a braid that meets the required characteristics as described above.

Further, in the present invention, the narrow woven fabric used as the core material is drawn out of the braid, and the ends thereof are connected by sewing 4 or an eye such that accessories such as metal fittings can be attached. It is possible to execute terminal processing such as processing 3 without relying on so-called Satsuma processing, and the use of the braid is greatly expanded.

That is, in the present invention, there is a possibility that the use of the conventional braid can be expanded to the field of general ropes.
