The present invention relates to a high-tenacity covering yarn (130) using a twisting machine (1), a manufacturing method thereof, and a cut-resistant glove (1000) knitted thereby, and examination of metal yarns during manufacturing of the high-tenacity covering yarn (130). (100) is provided with connectivity with a metal thread (tungsten thread or stainless thread) of the same material, and the unwinding auxiliary member 22 is formed in the metal thread bobbin 21 of the twisting device 1, and the metal thread bobbin 21 ), the 1st and 2nd coverings on the outer circumferential surface of the metal yarn 100 are sent and supplied at high speed, and the number of twisted yarns (T) of the 1st and 2nd covering is possible. While increasing (right-twisted and left-twisted yarns) as much as possible, the high-strength covering yarn 130 minimizes the thickness of the total diameter and gives softness and elasticity along with a round appearance with dense twisted yarn, etc. It relates to a high-strength covering yarn (130) with high tensile strength and cutting strength by increasing the twisting angle (θ) and making it possible to manufacture with the maximum appropriate twisting yarn, a manufacturing method thereof, and a cut-resistant glove (1000) manufactured thereby .

Specifically, the twisting device 1 is used, and a fastening bolt 221, an upper support washer 223, an unwinding body (unwinding body) and a lower A twisting device 1 of metal yarn (tungsten yarn or stainless yarn) having a structure of a loosening auxiliary member 22 composed of a support washer 224 and an upper support washer 223 is used. The unwinding auxiliary member 22 prevents the examination 100 of the metal thread 100 from friction, impact and cutting to the border portion of the metal thread bobbin 21 by high-speed sending and supplying the examination 100 of the metal thread, thereby stably sending 1 , To make it possible to manufacture the secondary covering yarns 1110 and 120. And the high-strength covering yarn 130 twists the primary high-strength polyethylene yarn 101 (High Performance Polyethylene yarn, HPPE yarn) on the outer circumferential surface of the screening 100 of the metal yarn (tungsten yarn or stainless yarn), and the secondary covering yarn (102) is twisted with nylon yarn to manufacture a high-strength covering yarn (130). At this time, even though the metal thread screening 100 is sent and supplied at high speed by the unwinding auxiliary member 22 of the twisting device 1, the metal thread screening 100 can be sent and supplied within the balloon spinning range, and the metal thread bobbin ( 21) does not occur due to friction, and the tension of the 1st and 2nd HPPE and nylon yarns 101 and 102 is smoothly adjusted to enable stable and uniform twisting, and the 1st and 2nd covering yarns High-speed rotation of the bins 31 and 32 is possible, so that the number of twisted yarns (T) of HPPE or nylon can be increased to the maximum (number of right and left edges), and the tensile force and binding force are strengthened, and the high-strength covering yarn (130) Minimizes the thickness of the total diameter of, has a soft yet elastic with a round appearance, and also the twisting angle (θ) generated by the primary and secondary covering yarns 110 and 120 on the outer circumferential surface of the metal yarn screening 100 It is formed large, and the maximum appropriate twist is possible, and since the pitch interval (P) between covering yarns is not generated, it can be protected from physical friction or sharp objects, etc. ) To provide a high-strength covering yarn 130 that maximizes workability and productivity during manufacture and has a soft touch, tensile strength and cutting strength, a manufacturing method thereof, and a cut-resistant glove 1000 manufactured thereby.

In general, the types of gloves include various functions such as medical gloves, surgical gloves, gloves worn by doctors and nurses during surgery or treatment, flight gloves, firefighting gloves, gardening gloves, military gloves, industrial gloves, sports gloves, etc. As a use having a fiber yarn used for these, gloves coated with the surface of knitted gloves knitted with cotton yarn, nylon yarn, span or polyester yarn, glass fiber, etc. are used.

In particular, protective gloves used in dangerous industrial sites where safety is important are used for the purpose of protecting the user's hand parts that are prone to injury by dangerous knop or sharp or sharp means, and metal thread (tungsten thread or Stainless steel yarn), high performance polyethylene yarn (HPPE yarn), and nylon yarn, etc., and twisted covering yarn to metal yarn (tungsten yarn or stainless yarn) to produce protective gloves. being manufactured with

These protective gloves not only protect the safety of the builder at the industrial site, but also prevent the gloves from being worn out quickly while ensuring the efficiency and safety of the builder.

On the other hand, military gloves, gloves worn by doctors and nurses during surgery or treatment, and various industrial sites that handle metal, glass, steel, etc. In order to safely protect the hand of a builder from various harmful factors such as copper and sharp objects, cut-resistant gloves 1000 are worn.

In the case of protective gloves, the examination of the metal thread (100), which is the core thread, has a specific gravity of 1.93 (g/cm 3) greater than 1 and a fine metal thread of 0.02 to 0.03 mm in thickness, so to prevent exposure from the outside, the examination of the metal thread (100) The outer circumferential surface is covered with high performance polyethylene yarn (HPPE yarn) and nylon yarn.

However, in the industrial field, there is also a problem of breaking up quickly depending on the type of work, but usually the number of rotations of the spindle according to the supply device of metal yarn (tungsten yarn or stainless yarn), the number of strands of screening 100 of one or two metal yarns , The pitch interval (P) of the covering yarn is small, so the tensile strength or cutting strength is weakened, and the protective function cannot be fully performed as a glove, and high-speed continuous shooting is impossible, especially on the outer circumference of the fine metal yarn (tungsten yarn or stainless yarn) As a result, the metal thread (tungsten thread or stainless thread) part of the protective gloves is exposed to the outside and is easily cut by impact, resulting in safety accidents.

For that reason, when manufacturing high-strength covering yarn, metal yarn (tungsten yarn or stainless yarn) uses the core yarn as a screening for the metal yarn, and high-performance polyethylene yarn (hereinafter referred to as HPPE yarn) and nylon yarn ), the direction of some of the covering yarns is different while twisting each covering yarn, but since the metal yarn (tungsten yarn or stainless yarn) of the metal yarn bobbin 10 is supplied directly in a wound state, friction with the metal yarn bobbin 21 The breakage phenomenon occurs, and it is difficult to send out quickly from the metal yarn bobbin 10, and even when sending out, this low-speed sending causes loose and twisted yarn during covering, resulting in uniform twisting and imbalance in tension control, resulting in abrasion strength or tensile strength of the covering yarn The phenomenon of falling occurs, and for the same reason, the pitch interval P between the covering yarns is not constant and the size of the pitch interval P is formed small. It has a problem that it is easily cut or easily damaged by physical friction or sharp objects, so that the function of the protective glove is lost.

In addition, when one metal thread (tungsten thread or stainless thread) is used as the core of the metal thread to cover the outer circumferential surface of the metal thread (tungsten thread or stainless thread), the diameter of the metal thread (tungsten thread or stainless thread) is 0.02 to 0.03 mm As HPPE or nylon yarn is wound and twisted at a size with a thickness, the metal yarn (tungsten yarn or stainless yarn) is frequently cut by the covering yarn, resulting in a decrease in tensile strength or cutting strength, and a single metal yarn (tungsten yarn) or stainless yarn) and a composite yarn of one metal yarn and HPPE yarn are used as the metal yarn screening 100 and twisted on the outer circumferential surface. Due to the exposure of metal thread (tungsten thread or stainless steel thread) after manufacturing protective gloves, the pitch interval (P) between covering threads is not constant or the pitch interval is formed large during low-speed continuous shooting. It is not only easily cut or easily damaged by physical friction or sharp objects, but also causes difficulty in the knitting process because the thickness supplied to the knitting needle is not constant when knitting protective gloves, and it is impossible to achieve maximum build-up and productivity. There was a big problem in providing a covering yarn with high strength and strong cutting strength, a manufacturing method thereof, and a cut-resistant glove manufactured thereby.

As described above, as a representative example thereof, in Korean Registered Patent Publication No. 10-2208801 (name: high-tenacity yarn and glove manufacturing method using the same/registration date: 2021.01.22), as is known in the publication, the core yarn 10 is circumferential The covered yarn 20 is formed by winding along, and the core yarn 10 includes a first core yarn 11 made of a metal component and a second core yarn 12 made of a metal component. The total thickness of the core yarn 11 and the second core yarn 12 is less than 0.07 mm, and the covered yarn 20 is made of poly yarn or nylon yarn of 70 to 80 denier, clockwise or counterclockwise. The first covered yarn 21 wound around the core yarn 10 in a clockwise direction, and a nylon yarn of 190 to 220 denier, on the outside of the first covered yarn 21 in the opposite direction to the first covered yarn 21 It includes a second covered yarn 22 that is wound, but the second covered yarn 22 is described as a high-tenacity yarn characterized in that it is covered with a cover.

In the prior art, 0.07 mm core yarn is used for the first core yarn stainless steel yarn and the second core yarn metal yarn, respectively. Alternatively, when a single strand is supplied from a stainless steel bobbin, friction with the bobbin or tension is not uniform due to a fine thickness with low cutting resistance, resulting in cutting during the covering yarn process, and the size of the second covering yarn is large. It goes through a complicated process of U-covering treatment by heat treatment or scratcher processing, and in the case of TPM (turns per meter) of the second covering yarn, it is 190 to 220 TPM, so it is not possible to form a strong covering yarn of about 1000 times, so the covering yarn The pitch interval of the second coated yarn is formed, and after manufacturing protective gloves, they are easily cut due to exposure of metal threads, etc., or easily impacted by physical friction or sharp objects, etc. there is.

In addition, in Korea Patent Publication No. 10-1890566 (name: glove manufacturing method using tungsten thread and glove/registration date: 2018.08.16.), as is known in the publication, tungsten having a diameter of 20 μm to 50 μm yarn, 200 denier HPPE yarn (High-pressure polyethlene) 1st HPPE yarn, 400 denier HPPE yarn (High-pressure polyethlene) 2nd HPPE yarn, and 70 denier HPPE yarn (nylon yarn), tungsten yarn and 1st HPPE yarn and a main yarn formed by twisting a one-dimensional yarn with a nylon yarn and a second HPPE yarn, which is a two-dimensional yarn, on the one-dimensional yarn. And auxiliary yarns formed by twisting spandex yarns and nylon yarns; and the main yarns are located on the side surfaces of the gloves, and the auxiliary yarns are knitted to be located on the inner surface of the gloves.

In the prior art, one main yarn 10 uses a tungsten yarn of 0.02 mm to 0.05 mm as a single yarn, but for the above reason, when a single tungsten yarn is supplied, friction or tension with the bobbin is fine with a fine thickness The pitch interval (2 It is easily cut due to exposure of tungsten yarn or stainless yarn), or easily impacted by physical friction or sharp objects, and tensile strength and abrasion resistance are reduced, as well as tungsten yarn, first HPPE yarn, nylon yarn and The total fineness of the 2 HPPE yarn is thicker than 0.52mmm, so the cutting strength after knitting gloves is rather high. There are problems with anti-knock gloves and protective gloves.

In addition, Korean Registered Patent Publication No. 10-2002591 (Name: High-strength cutting-resistant covering yarn with double screening of HPPE yarn and tungsten yarn and its manufacturing method and knitted product using the covering yarn/Registration date: 2019.07.16.) In, as known in the publication, in the covering yarn in which the covered yarn is wound along the outer circumferential surface of the screening, the screening is made of HPPE yarn with a diameter of 100 to 400D (Denier) as the first screening and tungsten with a diameter of 15 to 30 μm. As the second screening, each screening is arranged side by side in a line, and as mentioned above, one of the first and second covered yarns is clockwise, and the other one is counterclockwise. Thus, the covering yarns are wound in such a way that the first and second screenings are tightened while crossing each other to form a single coated layer at pitch intervals corresponding to the diameters of the covered yarns.

In the prior art, 100~400D HPPE yarn and 15~30㎛ tungsten yarn were used for the first examination and the second examination, respectively, and the covering yarn was selected from polyamide yarn or polyester yarn. It is used as a covering yarn, or one strand of polyamide yarn and one strand of polyester yarn are used as the first and second covering yarns, respectively. As the pressing force of the tensioner cuts and supplies at low speed, the bobbins of the 1st and 2nd coated yarns cannot exert a strong rotational force, so a pitch interval corresponding to the diameter of the coated yarn is formed, thereby cutting or objects, etc. Not only is it easily impacted from the cover, but also the wearability and build-up of the gloves are reduced due to the pushing phenomenon with heterogeneous components of HPPE yarn and tungsten yarn in the covering stage, and there is a limit to anti-knives and protective gloves due to a decrease in tensile strength and abrasion resistance.

And in Korea Patent Registration Registration No. 10-221326 (name: cut-resistant glove 1000 and manufacturing method/registration date: 2021.01.29), as is known in the publication, claim 1. cut-resistant glove 1000 It consists of an outer surface knitted with the main yarn 10 and an inner surface knitted with the auxiliary yarn 20. ), and a 200 denier HPPE covering yarn 13 and a 70 denier nylon covering yarn 14 twisted around the fine metal screening 11 and the HPPE screening 12 in opposite directions to each other. Configuration, and the auxiliary yarn 20 is a tungsten yarn having a configuration of a 70 denier nylon yarn 21 and a 70 denier spandex yarn 22 twisted in the form of a covering yarn. The cut-resistant glove 1000 is are listed.

The above technical configurations are two main yarns, and when the fine metal yarn, which is the main yarn, is supplied, the problem of cutting in the process of covering yarn due to uneven friction or tension with the bobbin with a fine thickness, the pushing phenomenon with heterogeneous components of HPPE yarn and fine metal yarn, and the fine metal yarn Tension is not uniform due to low-speed supply, resulting in cutting during the covering yarn process, easily being cut due to exposure of pitch intervals, etc., or being easily impacted by physical friction or sharp objects, and not only reducing tensile strength and abrasion resistance, but also reducing total It has a thick thickness of about 0.45mm or more, so the manufacturing process is not smooth during knitting and the function of protective gloves is lost. There was a big problem in providing a manufacturing method and a cut-resistant glove manufactured thereby.

Therefore, in the prior art, it is difficult to send out at high speed from the bobbin of the metal yarn in the fiber covering yarn device, and even when sending out, friction with the bobbin causes breakage, and the covering is uneven and the tension is not smoothly adjusted, making it difficult to provide stable screening. , The covering yarn is twisted at a low speed, the pitch interval between the covering yarns is not constant, the pitch interval is formed small, the number of twisted yarns (T) cannot be increased as much as possible, and the twisting angle (θ) generated by twisting on the outer circumferential surface of the screening It is difficult to make soft elasticity due to the small size and maximum appropriate false twist yarn, and the fineness and thickness of the total diameter are large, and it is difficult to maximize workability and productivity during knitting in the post-process. It is difficult to provide a high-strength covering yarn with high strength and a high-strength cut-resistant glove manufactured thereby.

The rotating part 2221 of the loosening body 222 is configured to stably idling between the lower support washer 224 and the upper support washer 223, and when the metal thread screening 100 is quickly sent out and supplied The friction with the metal thread bobbin 21 does not cause the breakage phenomenon, and the rapid sending of the metal thread screening 100 and the friction between the metal bobbin prevent the breakage phenomenon from occurring, and the first and second covering thread bobbins (31) According to the winding speed of (32), the rotation of the supply of the metal thread screening 100 of the unwinding auxiliary member 22 is adjusted, so that the tension of the metal thread screening 100 can be stably adjusted and supplied.
With the rapid delivery and supply of the metal thread screening 100 by the device of the loosening auxiliary member 22, the twisting angle θ that occurs when the outer peripheral surface of the metal thread screening 100 is twisted is increased, and the maximum appropriateness is achieved. By making it possible by continuous yarn, etc., the pitch gap between the covering yarns does not occur and the metal yarn is not exposed, so it can be protected from physical friction or sharp objects, that is, the pitch gap (P) between the covering yarns is constant And the pitch interval (P) is formed large, the number of ties (T) is increased as much as possible, and the covering angle caused by the twisting of the outer circumferential surface of the metal thread screening (100) is large, and it is soft with a round appearance with the maximum appropriate twisting. will create resilience.
In the manufacture of the high-strength covering yarn 130 of the present invention, the metal yarn screening 100 maintains strength and connectivity between metal yarns (tungsten yarn or stainless yarn) by using three metal yarns with a diameter of 20 to 30 μm However, when a conventional metal thread (tungsten thread or stainless thread) of 20 to 30 μm is used, friction with the bobbin or tension is not uniform due to its fine thickness, so it is cut during the twisting process When this occurs, and one or two fine metal yarns (tungsten yarn, stainless steel yarn) and synthetic fiber yarn (HPPE yarn, nylon yarn) are supplied and plied to twist the metal yarn screening 100, the metal yarn (tungsten yarn) Yarn or stainless thread) and synthetic fiber thread are heterogeneous components, causing shedding, and low-speed supply of fine metal thread (tungsten thread or stainless thread) and uneven tension cause cutting during the twisting process, resulting in pitch As the gap P increases, it may be easily cut due to exposure or the like, or easily impacted by physical friction or sharp objects, and the tensile strength and wear resistance may be deteriorated. In contrast, the metal thread screening 100 of the high-strength covering yarn 130 of the present invention uses three metal thread screenings 100 of the same material to have tensile strength and cutting strength with relatively stable twisted yarn.
On the outer circumferential surface of the core 100 of the metal yarn, the first and second covering yarns 101 and 102 supplied from the first and second covering yarn bobbins 31 and 32 are twisted with S twist or Z twist, and 1 The primary covering yarn 110 uses three 100 denier three 300 denier reinforced polyethylene yarns (HPPE yarn), and the secondary covering yarn 120 uses three 30 denier three 90 denier nylon yarns and twists them to form a covering yarn. manufacture
At this time, it is preferable that the total diameter of the high-tenacity covering yarn 130 be 0.23 μm or less in fineness.
The total diameter of the high-strength covering yarn 130 reinforces the tensile strength and binding force, and the thickness of the total diameter of the high-tenacity covering yarn 130 is minimized to create a round appearance and softness and elasticity. It is possible to maximize build-up and productivity during manufacturing.
In addition, the number of twisted yarns (TM) of the covering yarn (the number of right and left edges) is the maximum appropriate number of twisted yarns (TM) for 1 m; The primary covering yarn 110 has 2,500 to 3000 twisted yarns (TM), and the secondary covering yarn 120 has 1,000 to 3000 twisted yarns (TM), and the angle with the central axis generated at this time is 30 ~ 42 ° twisting angle (θ) is formed so that there is no pitch interval (P) between twisted yarns.
In the above configuration, the metal yarn screening 100 is a high-strength covering yarn 130 with high tensile strength and cutting strength by strengthening tensile force and binding force without exposure from the primary and secondary covering yarns 101 and 102 It is possible to manufacture, and it is possible to manufacture a high-strength cut-resistant glove 1000 that can be protected from physical friction or sharp objects.
