Description

Stretch Yarn Including Metal Filament and Textile Product Comprising the Yarn}

The present invention relates to a yarn having a cut resistance including a stainless steel wire and a strong metal wire, and a glove or other textile product having a cut resistance obtained by knitting or knitting the yarn. It is about.

For example, gloves, work clothes, shin guards, etc. worn by workers at the workplace using cutlery, such as meat processing sites, or scattered glass fragments, may be accidentally cut on the hands or body. In order to prevent the cut off when it touches, a cut resistance is calculated | required. In order to obtain woven fabrics and knitted fabrics having such cut resistance, a yarn containing stainless steel wire is used.

If the wire diameter is too thin, the stainless steel wire will lose its cut resistance, and if the wire diameter is thick, the stainless steel wire will lose its flexibility when used as a medical material. Therefore, the diameter of the stainless steel wire used is 30-80 micrometers (microns) normally, and the thread which twisted several stainless steel wires together, or the stainless steel wire, high-strength polyethylene fiber, and aramid fiber twisted together in order to provide flexibility is used. It is becoming.

For example, Patent Literature 1 discloses an insert yarn formed by twisting different twisted yarns made of multifilament yarns of a plurality of stainless steel fibers around a twisted yarn made of multifilament yarns of stainless steel fibers, and a synthetic yarn. A Raschel letter is described that includes a chain knitting yarn composed of multifilament yarns of fibers or metal fibers.

In addition, Patent Literature 2 winds about 200 denyl aramid fiber yarn in one direction to form a first coating on a screen along a 30 to 100 micrometer stainless steel single wire and about 133 to 531.6 denyl aramid fiber spun yarn. In addition, there is described a knitting yarn coated with a resin and a work glove woven from the knitting yarn, in which a strong fiber obtained by winding a synthetic fiber yarn of about 80 to 120 deniers in a reverse direction to the first coating to form a second coating.

Patent Document 3 also describes an electromagnetic wave absorber formed by Z and S twisting a plurality of polyester fiber bundles having a thickness of about 80 µ in a plurality of polyester fiber bundles as a yarn used to fabricate a cloth having electron shielding properties. . Since this yarn is excellent in elasticity and has sufficient strength and flexibility, it is said that the yarn can be easily fabricated with a normal loom.

As described in Patent Literature 1, by twisting a plurality of stainless single wires together or by twisting a stainless steel wire and a synthetic resin fiber with each other, the yarn including the stainless steel wire can be provided with some flexibility and elasticity. However, the flexibility and elasticity of the stainless steel wire-containing yarn obtained by such a method may be sufficient to produce a jikji or letter used for a portion where very flexible flexibility is required, such as a finger portion of a glove. There was no. In patent document 1, although the required flexibility is acquired by using a Rassel letter in the horizontal direction, more flexibility is calculated | required.

In addition, as shown in Patent Literature 2, in a yarn using a stainless steel wire as a screening company, the elasticity cannot be expected, and even if a high cut resistance can be obtained, when used as a glove, the bending resistance of the finger portion is reduced. It was big and had the flaw that we could only get what was not good at the time of use.

On the other hand, a thread using a stainless steel wire as a cover yarn wound around the screen may be considered by using a synthetic fiber as the screening of the covering yarn.However, to manufacture the covering yarn, the cover yarn is wound on a cover yarn bobbin by using a weaving machine. It is necessary to return to the examination passing through the center of the bobbin while releasing the cover yarn from the bobbin. By the way, in the prior art, when the non-stretchable stainless steel wire is wound around the cover yarn bobbin or returned to the screening yarn, breakage of the yarn frequently occurs, and there is a problem that it is impossible to continuously manufacture the yarn.

This invention solves such a problem, is excellent in flexibility, has great elasticity, and is excellent in the metal wire containing elastic yarn which can manufacture the extremely flexible woven fabric or letter, and the resistance to the window wire manufactured by such metal wire containing elastic yarn It is a subject to provide medical products and other textile products.

The present invention provides a twisted yarn to a covering yarn using a high-stretch yarn as the screening and using a strong metal wire-containing yarn (a yarn of a strong metal wire and a yarn of the strong metal wire and synthetic fibers or natural fibers) for the screening. It is solved. As said high stretch yarn, although the yarn of a polyurethane fiber is the most outstanding, the rubber yarn of a natural rubber or a synthetic rubber is mentioned. Wool, acetate, polyamide, polyester, etc. can also be used for the examination of the metal wire containing elastic yarn used for the use which may be small in elongation. As a strong metal wire, although a stainless steel wire is practical from a viewpoint of economy, corrosion resistance, etc., as another thing, the wire rod of metal with high cutting strength, such as high strength steel, aluminum alloy, pure titanium, and a titanium alloy, is mentioned.

Although the strong metal wire containing yarn of this invention can return the cover yarn to the core wire 10 with a twisting machine by drafting (extending and supplying) the screening 10, it is generally good to return it to a covering machine.

That is, by using a yarn of polyurethane fiber as the screening, the cover yarn including the stainless steel wire is wound around the screening with a covering machine, so that the elasticity is extremely large, and the periphery of the thread is tightly covered with the stainless steel wire. Therefore, the metal wire-containing stretchable yarn provided with the cut resistance of this invention which is high in cut resistance and can be produced continuously using a covering machine can be obtained. In addition, gloves or other medical products or textile products produced using the metal wire-containing stretchable yarn according to the present invention have sufficient flexibility that does not interfere with the bending of the finger.

As described above, when the covering yarn is manufactured by using a machine that unwinds the cover yarn from the bobbin rotating around the screening, and passes through the core of the bobbin that wound the covering yarn, that is, the cover yarn, and winds the wound. When using a stainless steel wire as a cover company, there existed a problem that breakage of the thread of a cover company was frequent.

In the present invention, the yarn bobbin 2 is rolled to the rolling bearing 8 when the yarn metal bobbin 2 is wound around the yarn bobbin 2 of the stainless steel wire or other strong metal wire from the yarn bobbin 2 to the cover yarn bobbin 3 using a weaving machine. The bobbin width (W) of the metal bobbin and the traverser at the time of turning the cover yarn by using the metal bobbin instead of the conventional bobbin made of synthetic resin as the cover yarn bobbin (3). The problem of thread breaking was solved by adjusting the stroke S of 9) to an accurate positional relationship.

When the strong metal wire 4a is wound around the cover yarn bobbin 3, the yarn bobbin 2 is supported by the rolling bearing 8 so that the pulled strong metal wire 4a causes tension fluctuations due to variations in the release resistance. When the yarn bobbin 2 rotates minutely in accordance with the tension variation of the yarn, the tension variation acting on the strong metal wire 4a during the change is alleviated, and the thread break of the strong metal wire 4a can be prevented.

Further, in the conventional apparatus using a synthetic resin bobbin as the cover yarn bobbin, even when the stroke of the traverser 9 is carefully adjusted during the winding of the strong metal wire 4a to the cover yarn bobbin 3, it occurs during the actual winding. Due to the deformation of the bobbin 3, as shown in Figs. 2 (b) to 2 (d), the amount of winding of the thread increases or decreases at the end of the bobbin 3 so that the wrapping overlap 3a or the winding collapses. (3b) occurs. If such overlapping of the windings 3a or winding collapses 3b occurs, when the strong metal wire 4a is released from the cover yarn bobbin 3 at the time of covering, the unwinding resistance fluctuates at both ends of the bobbin so that the thread breakage occurs. It was happening. In the seventh aspect of the present invention, thread breaking during covering is prevented by winding the cover yarn accurately on the bobbin using a metal bobbin without deformation as the cover yarn bobbin.

That is, the invention of claim 7 uses a high-strength yarn as the screening yarn 10 as a cover yarn 4 by enabling the work of returning the strong metal wire to the screening by using a covering machine which has not been possible in the past. (4a) to (4c) of the strong metal wire and the synthetic fiber, it is possible to produce a metal wire-containing stretched yarn having both a high elasticity and a cut resistance with a covering group.

The metal wire-containing elastic yarn according to the invention of claim 1 is wound around the strong metal wire-containing yarns 4a and 4c in the screening 10 made of high-stretching yarn to form a cut resistant coating layer around the screening. It is a metal wire containing stretchable yarn.

The metal wire-containing stretched yarn according to the invention of claim 2 of the present application is characterized in that the strong metal wire-containing yarn is wound around the core wire by the covering machine 1 in the metal wire-containing stretched yarn having the above means.

The metal wire-containing stretched yarn according to the invention of claim 3 of the present application is a layer formed by winding a strong metal single wire or stranded wire 4a in the screening, and a strong metal single wire or stranded wire in the metal wire-containing stretched yarn provided with the above means. The plywood 4b, 4c of the high-strength polyethylene fiber or aramid fiber is wound around to form two layers of resistance-resistant coating layers.

In addition, in the metal wire-containing stretched yarn according to the invention of claim 4 of the present application, in the metal wire-containing stretched yarn having the above means, the core wire is polyurethane monofilament or multifilament, and the strong metal wire is stainless single wire or stranded wire 4a. It is characterized by that.

The dough according to the invention of claim 5 of the present application is a dough made by weaving or knitting a metal wire-containing stretchable yarn provided with the above means.

Moreover, the fiber product which concerns on invention of Claim 6 of this application is a fiber product characterized by including the dough provided with the said means.

The strong metal wire-containing yarn according to the invention of claim 7 of the present application includes a metal cover yarn bobbin (3) from a yarn bobbin (2) in which the strong metal wire of the strong metal wire-containing yarn according to claim 2 is supported by a rolling bearing (8). In this case, the metal bobbin is loaded from the metal bobbin loaded on the covering machine 1 and wound around the screen 10.

The fiber product according to the invention of claim 8 of the present application is a fiber product characterized in that it contains a dough formed by weaving or knitting a metal wire-containing stretchable yarn according to the invention of claim 7.

The strong metal wire-containing yarn is a yarn made of a stainless steel wire or other strong metal wire only or a yarn of the strong metal wire with other natural fibers or synthetic fibers. As other natural fibers and synthetic fibers, high strength polyethylene fibers and aramid fibers are particularly preferable. A high strength polyethylene fiber or an aramid fiber-containing yarn is a yarn made of only high strength polyethylene fiber, a yarn made only of aramid fiber, a plywood of high strength polyethylene fiber and aramid fiber, a plywood of high strength polyethylene fiber or aramid fiber and stainless steel wire, a high strength polyethylene fiber or aramid fiber And pulverization with other natural or synthetic fibers.

As the cover yarn, a strong metal wire, for example, a stainless steel wire (stainless single wire or stranded wire), or a combination of strong metal wires and natural fibers and synthetic fibers including polyamide, polyethylene, and aramid fibers can be used.

Larger cracking than that of a single cover by double winding (double covering) the composite yarn 4c of the strong metal wire 4a to the strong metal wire and the high strength polyethylene fiber or aramid fiber around the screen 10. It can be given generating, frictional resistance and strength. Then, by using a synthetic fiber, a strong metal wire and a synthetic fiber as a synthetic yarn as the cover yarn of the second layer (outer layer), it is possible to improve the feeling and feel when dyeing, woven or knitted fabric is used. In addition, by using high strength polyethylene fibers and aramid fibers as the synthetic fibers twisted together, it is possible to impart greater cut resistance and strength than when using other synthetic fibers.

The metal wire-containing stretchable yarn of the present invention can be used for woven papers and letters of all textile products requiring cut resistance and friction resistance, but is particularly suitable as a yarn for knitting or knitting work gloves requiring great flexibility in the finger portion.

According to this invention, it is possible to obtain a cut-resistant yarn having great elasticity which could hardly be achieved in a conventional stainless steel-containing yarn having cut resistance. Therefore, by using the thread of this invention as a thread of a woven paper or a letter, the cloth which is highly flexible and has a bending resistance with little bending resistance can be obtained. Therefore, as a thread used for manufacturing medical products and other textile products equipped with disaster prevention and safety, such as gloves, socks, underwear, vests, knee pads, elbow pads, etc. worn at metal processing sites, food processing sites, construction sites, etc. It is optimal.

When using a polyurethane yarn as the examination of the metal wire containing elastic yarn of this invention, the thing of 10-350 denyl is preferable, The thing of 44-157 decidex is especially suitable as a thread which knits a glove. When using a stainless steel wire containing yarn as a cover yarn of the metal wire containing elastic yarn of this invention, when manufacturing the yarn which knits 1.2-50 micrometers of wire diameters of a stainless steel wire, and a work glove, it is preferable that it is 20-40 micrometers. As the cover yarn, a fused yarn of stainless steel wire or stainless steel wire and high strength polyethylene fiber or aramid fiber is used.

As high-strength polyethylene fiber, the Dyneema (trademark) 55-1760 decidex of the Japanese oriental control agent is mentioned, for example. The preferable thickness at the time of twisting with 28 micrometers stainless steel single wire is about 440 decidex.

As shown in FIG. 1, the strong metal wire 4a used as a cover yarn is wound up from the yarn bobbin 2 supplied from a manufacturer to the cover yarn bobbin 3 using a weaving machine. At this time, the yarn bobbin 2 is supported by the rolling bearings 8 and 8 and set in the machine, and the yarn (strong metal wire) 4a is released from the bobbin 2 in the axial direction. The unwrapped strong metal wire 4a is wound by the tangential direction to the rotating cover bobbin 3 made of metal. When thus wound, the stroke S of the traverser 9 guiding the yarn in the width direction of the cover yarn bobbin 3 and its return position are defined by the bobbin width W of the cover yarn bobbin 3 and its edges. Accurately aligned to the inside position of (13), and the overlapping (3a) of the thread in the part adjacent to the edge 13 of the bobbin as shown in FIG. 2 (b), (c), (d) In order not to generate | occur | produce (3b), as shown to Fig.2 (a), it winds up uniformly. When using twisted yarns in which a plurality of strong metal wires are twisted on the cover yarn, or twisted yarns between the strong metal wire and synthetic fibers, the yarn twisted using a twisting machine is wound around the cover yarn bobbin 3.

Here, Figure 2 (a) is a case where the traverse is normal, (b) is a case where the traverse width (S) is wider than the bobbin width (W), (c) is a case where the traverse width (S) is narrower than the bobbin width (W) , (d) is a phenomenon that occurs when the positions of the traverser 9 and the bobbin 3 are shifted, and such a case occurs even when the bobbin 3 is deformed during thread winding. When the overlap 3a and the collapse 3b of a thread generate | occur | produce, large tension fluctuation arises in a cover yarn when a cover yarn is released from this part at the time of covering. Strong metal wires without elasticity are easily broken by such tension fluctuations.

3 to 6, the covering machine 1 usually has the screening shaft 10 drawn out in a tangential direction from the screening bobbin 11 mounted on the shaft so as to be freely rotated at the bottom of the machine. It is mounted on and wound around the braided bobbin 12 which is rotationally driven by a drive motor (not shown). The examination 10 passes through the shaft center of the hollow shaft 15 which is rotationally driven by the drive motor which is not shown in figure, and the cover yarn bobbin 3 is loaded in this hollow shaft 15. Immediately in front of the plywood bobbin 12, a take-out roller 17 which is rotationally driven by a drive motor (not shown) is provided, and the screening 10 is drawn out from the screening bobbin 11 at the circumferential speed of the take-out roller 17. The circumferential speed of the take-out roller 17 is slightly slower than the thread rewind speed of the braided bobbin 12 (for example, a circumferential speed of 97% of the rewind speed).

The cover yarn bobbin 3 which wound the strong metal wire 4a was wound on the hollow shaft 15 of the covering machine, and rotates the hollow shaft 15 while pulling out the screening 10, so that the cover yarn bobbin ( From 3), the cover yarn 4 is unwound while ballooning by the centrifugal force according to rotation, and it winds around the screening 10. The density of the wound cover yarn (the number of turns) is determined by the ratio of the rotational speed of the take-out roller 17 and the rotational speed of the hollow shaft 15, and the winding direction (Z-direction or S-direction) is the hollow shaft 15. It is determined by the direction of rotation.

3 shows an example of the case of single covering, and FIGS. 4 to 6 show an example of the case of double covering. In the example of the single covering of FIG. 3, it uses the 40 denier polyurethane fiber as the screening 10, and is drawing out in the state extended twice. The cover yarn 4a is a stainless single wire of 28 micrometers in diameter. The number of turns is, for example, Z270T / M (270 windings in the Z direction per 1m of the examination).

In the double covering of Fig. 4, high-strength polyethylene fiber 4b of two twists of 75 deniers is used as the cover yarn of the first layer (lower end) as the cover yarn of the 28 mm stainless steel single wire 4a and the second layer (the upper end). I use it. The number of turns of the first layer is Z270T / M, the number of turns of the second layer is S270T / M, and the rotation speed of the hollow shafts 15 and 15 is 3,000 rpm. The material and the withdrawal speed of the screening 10 are the same as those of FIG. 3.

In the double covering of FIG. 5, in contrast to FIG. 4, a high-strength polyethylene fiber 4b of two twists of 75 deniers is used as the cover yarn of the first layer, and a stainless single wire 4a having a diameter of 28 µ as the cover yarn of the second layer. Doing. The number of turns of the first layer is S270T / M, the number of turns of the second layer is Z270T / M, and other covering conditions are the same as in FIG.

In the double covering of FIG. 6, a stainless steel single wire 4a having a wire diameter of 28 μm as a cover yarn of the first layer, and a weaving yarn 4c of a high-density polyethylene fiber of 75 denyl and a stainless steel wire wire having a wire diameter of 28 μm as the cover yarn of the second layer. Is using. Other covering conditions are the same as in FIG.

The metal wire-containing stretched yarn thus obtained is woven into a woven fabric or knitted as a glove or other medical product in the same manner as a general covering yarn with polyurethane yarn as the screening. The resulting paper and letters have great elasticity and flexibility in all directions. In addition, since the yarn is covered with a strong metal wire, it exhibits great resistance against cutting, tearing, friction, and the like caused by cutting. Therefore, by knitting or knitting with the metal wire-containing stretchable yarn of the present invention, it provides not only cut resistance to prevent cuts caused by cutting, but also disaster prevention or safety to prevent abrasions and lacerations, Work gloves and other medical supplies with flexibility and elasticity can be provided.
