It concerns a safety cover made of that thread.

[0002]

2. Description of the Related Art Stainless steel wire strips and
Threads resistant to cutting using high-strength aramid threads, such as EI Dupont de Nemours Kevlar, or gloves made from them are described in Byrnes et al., U.S. Pat.
4,449 and Bettcher in U.S. Pat. No. 4,470,251. These gloves have been very successful. Another fiber, a high strength drawn polyethylene fiber manufactured and sold by Allied, Inc., Morris County, NJ, USA, has also been used in place of aramid fiber to demonstrate its excellent cut resistance. Allied fibers are sold under the name Spectra and are described in detail in U.S. Pat. No. 4,413,110 to Kavesh et al. Applicant's co-pending application No. 07 / 529,241 is high strength yarn or fiber or Hoe of Charlotte, NC
chst Celanese sells under the name Vectran HS
Disclosed and claimed composite yarns that are resistant to cutting utilizing components made of Vectra liquid crystal polymers.
This yarn, or fiber, is about as strong as the high strength aramid fiber sold under the name Kevlar. To applicants' experience to date, normal strength fibers do not provide the high cut resistance and other desirable properties that high strength fibers have when used in composite yarns.

[0003]

SUMMARY OF THE INVENTION The present invention is made of Vectra liquid crystalline polymer to provide composite yarns with high cut resistance comparable to high strength synthetic yarns or composite yarns of similar construction using fibers. Provided is a knittable composite yarn that is resistant to cutting using a twisted yarn, fiber, or material. The yarn or fiber used in the present invention is from Charlotte, North Carolina.
Hoechst Celanese is a high performance but normal strength multifilament yarn sold under the name Vectran M. Regular strength twine made of Vectran is also the subject of this invention. For purposes of definition, a normal strength fiber or thread shall have a tensile strength of less than 10 grams per denier (gpd), a high strength thread or fiber shall be greater than 10 grams per denier,
And typically greater than 20 grams per denier (eg Kevlar, Spectra and Vectra HS
Have a tensile strength of greater than 20 grams per denier). High strength yarns or fibers also have higher tensile modulus than normal strength fibers, for example a minimum of 500 grams per denier.

Vectran M has a tensile strength of 9 grams per denier and a tensile modulus of 1 denier
It is about 425 grams. It has higher wear resistance than high strength aramid fibers such as Kevlar, and
It has much higher heat resistance than high-strength drawn polyethylene fibers such as a, so Kevlar and Spectra have their own when used in apparel and especially in cut resistant yarns used for gloves that are resistant to cutting. You can overcome the flaws that were present. At the same time, quite surprisingly, this normal strength synthetic material is Kevla.
It offers almost the same advantages that r, Spectra and Vectran HS have over cuts and other properties of composite yarns over other normal strength materials. Therefore, knit fibers suitable for gloves and other safety coverings using Vecran M not only provide similar cut resistance, but also aramid fibers or aramid and nylon.
It is more resistant to self-abrasion than similar fibers made from a combination of fibers, and is itself non-abrasive and comfortable to wear. Moreover, such fibers do not damage the fibers when washed at the elevated temperatures normally used for industrial fibers, as they do with the cut resistance made of yarns containing high strength drawn polyethylene. In addition, Vectra
Compared to high strength fiber, nM has the same or lower extension under the same load, so it prevents the wire from breaking when it is braided or when the composite yarn is bent sharply. It is advantageous to use wire cores in combination when forming a composite yarn. Vect
The ran M is much cheaper than the Vectran HS and is now half the price.

SUMMARY OF THE INVENTION The present invention provides a cut resistant yarn suitable for machine knitting. Preferably, it comprises a core, a wrap around the core, and another, or second, wrap around the first wrap in opposite directions, the wick, the first wrap, and the second wrap. At least one wrapping is 10 per denier
It is composed of liquid crystal polymer fibers with a tensile strength of less than gram. The terms "first" wrapping and "second" wrapping used above and in the claims are used to distinguish between a plurality of wrappings, the first and the first with respect to the core of these wrappings. It does not indicate the positional relationship of 2. Conveniently, it is not necessary to use high strength synthetic fibers for the composite yarn in order to obtain high cut resistance in both core and wrapping. Cut resistance is a flexible metal strip, for example,
The wire can be reinforced by using it as a core element or wrapping as part of the yarn.

One preferred cut resistant yarn suitable for machine knitting constructed in accordance with the present invention is a core composed of synthetic fibers and a means for bundling core fibers,
Two wrappings around a bundle of cores and two synthetic fibers wound in opposite directions on each core wrapping
One of the synthetic fibers and / or the core is a liquid crystal polymer having a tensile strength of less than 10 per denier. In the preferred embodiment, the core fibers that bundle the cores are two denier relatively low synthetic wraps, each wound in opposite directions.

Another preferred construction of the cut-resistant yarn embodying the present invention comprises a core having glass fibers and a wrapping around the core, preferably one of the wrappings. One or two are liquid crystal polymer fibers having a tensile strength of less than 10 grams per denier. This and other preferred threads are made of nylon or polyester covering
I have a wrap. In order to obtain features not found in normal strength liquid crystal polymers, yarns with normal strength liquid crystal polymer fibers require fibers that are resistant to high strength cuts, such as Kevlar 29. You can choose from high-strength aramid, high-strength stretched polyethylene such as Spectra, and high-strength liquid crystal polymers such as Vectran HS.

Another embodiment of the present invention is a liquid crystal having a tensile strength of less than 10 grams per denier, instead of one or more flexible metal wires as found in the embodiments described above. A constant number of filaments (eg 1-50 filaments each of 10-500 denier) with a considerable denier of polymer fibers is used.

The present invention further provides a machine-knit apparel product that is cut resistant, such as one such product having a softness, at least a portion of which is made of a yarn having a construction as described above. It is a glove that has. Gloves or other apparel products using the preferred thread construction not only have high resistance to cutting, but also have excellent wearing comfort and comfort, requiring no repair during use,
Non-abrasive, aesthetically pleasing, washable and wearable for extended periods. The above as well as additional features and advantages of the present invention will become apparent in the following detailed written description.

The glove illustrated in FIG. 7 is an example of a safety apparel product using the present invention, and is used for food processing, knives, or materials with sharp edges, such as metal plates and the like. A safety or protective glove suitable for being worn by workers in other industries in which things are handled, the composite multi-filament yarns B, C, constructed according to the invention.
It is made of D, E, F or G (FIGS. 1 to 6).
The glove A has normal fingers and thumbs 4, 6 and the wrist portion 8 contains elastic thread, or twine and arm fold overwrapping 9. This glove was made using conventional methods and a glove knitting machine.

All yarns consist of a core and wrapping and are made using conventional winding techniques. The core is one or a plurality of central threads extending in the length direction of the thread. The wrapping or wrap is a strip that is wound around the core continuously or in a form that does not or does not adhere to the adjacent winding. All of these threads use liquid crystal polymer fibers with a tensile strength of less than 10 grams per denier. The preferred constructions of yarns using the present invention only provide comparative cut resistance such as high strength aramid, high strength drawn, or extended chain polyethylene, or high strength liquid crystal polymers, and exhibit defects in many instances. It does not contain such high strength synthetic fibers.

In some preferred embodiments, metal wire, particularly fully annealed stainless steel, is used as the core element and / or the wrapping to create high cut resistance. . 110,000 to 140,000 pounds (49,830 to 63,4) per square inch (6.45 square centimeters)
Fully annealed No. 304 stainless steel with a tensile strength of around 20 kilograms) is considered to have the best flexibility and life. Other embodiments may replace glass wire and its function in some cases with glass
Fibers or liquid crystal polymer fibers with a few high denier filaments with a tensile strength of less than 10 grams per denier are used. The liquid crystal polymer fiber used in these examples and having a tensile strength of less than 10 grams per denier is made of stainless steel.
It has a higher tensile strength than steel, and
Less malleable than wire. Vetran M has an initial tensile modulus of 400-500 grams per denier per denier. 8 per denier
It has a tensile strength of about 10 to 10 (typically, a tensile strength at break), and its extensibility is about 2.0%. The overall diameter of the yarn according to the invention is less than 0.05 inches (0.127 centimeters), preferably less than 0.03 inches (0.0762 centimeters) to facilitate machine knitting. Actually 0.005 inch to 0.035 inch (0.0127 cm to 0.0889 cm)
The result is a thread that is resistant to cutting of the desired quality.

One preferred embodiment of the present invention is shown in FIG. Thread B is suitable for machine knitting to make gloves A and comprises a core portion 10 and synthetic fibers 12, 14, 16 wound around the core in triples in opposite directions. The fact that each successive wrap is wrapped in the opposite direction to the previous one balances the force on the wrap, preventing the thread from unnaturally twisting or twisting, and further wrapping Helps to secure the to the core 10. Wick 10 is Vectran M and fully annealed stainless steel wire 20
Etc. have a filament of 900-1500 denier multifilament liquid crystal polymer fiber with a tensile strength of less than 10 grams per denier, and a diameter of 0.00
It is 3 inches (0.00762 centimeters). wrapping
12 has a tensile strength of less than 10 grams per denier
A 440 denier multifilament liquid crystal polymer fiber strip wrapped around the core 8-10 times per inch (2.54 centimeters) and wrapped.
Each of 14 and 16 is 420 denier nylon and is wound at a rate of 8 to 12 times per inch (2.54 cm), but polyester of that denier number may be used. Advantageously, the core is a multifilament normal strength polymer fiber strip such as Vectran M fiber strip. Multifilament strips are very linear and slip well against other parts during manufacture and use of apparel products made therewith. Multifilament cores of normal strength have a relatively low drawability and during knitting the yarn takes up most, if not all, of the load on the yarn. Also, it seems that the flexibility of the core part of the thread is made higher than that of other metallic cores to make the thread easy to knit. It also improves cutting resistance. The use of multifilamented normal strength liquid crystalline polymer fibers such as Vectran M as the wrapping significantly increases the yarn cut resistance. The first wrapping 12 provides a backup surface of the desired hardness of the outer wrappings 14,16, each of which has a tendency to fill the valley just below it. The multi-filament wrappings 12, 14, 16 are wrapped flat around the core to aid in the knitting process, and have a smooth surface that is aesthetically pleasing and has a non-abrasive surface that is both heat resistant and comfortable to wear. Make up.

Another preferred embodiment of the present invention is shown in FIG.
Shown in. The thread C has a core portion 30 and multiple wrappings 32, 34, 36,
Made of 38 and 40, these wrappings, with the exception of wrapping 36, are in turn spirally wound in the opposite direction to the previous one, balancing the forces on the wrapping and making the thread unnatural. Prevents the tendency to twist and get tangled, and helps to fix the wrapping on the core. Core 30 is for denier such as Vectran M
It is a multifilament strip of 750 denier liquid crystal polymer fibers with a tensile strength of less than 10 grams. The first two wraps are the same, but wound in opposite directions around the core 30, each with 70 denier multifilament nylon fiber, 6 per inch (2.54 centimeters) along the core. Wrapped at the rate of winding. These two wraps bundle the filaments of the core and thus are more integrated as a thin layer of filaments for sharp objects where the core may be exposed when the thread is used. It is believed that such configurations with multiple filaments in a bundle are difficult to cut, as they correspond as an entrapped material. The bundled core filaments also provide a fairly cylindrical and desirable uniform shape, which is convenient for further wrapping. The third wrapping 36 is two (or in the preferred embodiment 1 to 3) fully annealed stainless steel wire, each having a diameter of 0.0016 inches (0.
The first two wrappings are unidirectionally wrapped around the core 30 with a strip (00406 cm)
32 and 34 are wound evenly at a rate of 8 times per inch (2.54 centimeters). The length of this wire is about 35% longer than the length of the core, and therefore, when used, is the same amount as the length of the straight core, so steel is used rather than the straight core of twine of the same diameter. The quantity is increasing. Since the wires are spirally wound at intervals, knife teeth or other sharp objects that approach the thread at angles other than the wire's helix should be cut into the composite thread at multiple positions. Therefore, the resistance is higher than that of the core wire which is straight and prevents the wire from being cut at one time. Fourth wrapping
38 has a tensile strength per denier such as Vecrtan M
400 denier strips of liquid crystal polymer fiber less than 10 grams, wrapped in the opposite direction of the wire and wrapping 34, each wrap being adjacent to the next wrap, thereby providing a third wrap Almost completely. The fourth wrap 40 is 840 denier nylon or polyester fiber,
The fourth wrapping is wound in the opposite direction and each turn is in close proximity to the adjacent turns, thus almost completely covering the fourth wrapping. Although made of a material that has a relatively low cut resistance, the fifth wrapping gives the thread a suppleness, and because the material is soft, flexible and non-abrasive, it is comfortable with the wrapping made of the thread Will give you To facilitate machine knitting on conventional knitting machines, the final diameter of this yarn is 0.020-0.030 inches (0.05
08-0.0762 cm), preferably 0.02
Less than 5 inches (0.0635 centimeters).

Another preferred embodiment of the present invention is shown in FIG.
Shown in. Thread D is a core 44 made of liquid crystal polymer fiber with a denier of 1500 and a tensile strength per denier of less than 10 grams, such as Vectran M, and 0.003 inch (0.00762 cm) diameter, each well annealed.
First and second wrappings 46,48 made of stainless steel wire and wrapped around the core in the opposite direction at a rate of 8 turns per inch
It is made of and. It is also possible to omit one of the wire wrappings to increase flexibility if cut resistance must be lower. A third wrap made of a 400 denier liquid crystal polymer fiber with a tensile strength of less than 10 grams per denier, such as Ventran M, is wrapped around the core and wire, with each turn in close proximity to the adjacent turns. So it almost covers the core and wires. A fourth wrap of 630 denier nylon, or polyester in lieu of it, is wrapped in close proximity to the third perimeter and opposite the direction of winding of the third wrap. Also, the third and fourth wrappings 50,
52 is a 400 denier liquid crystal polymer fiber, both with a tensile modulus of less than 10 grams per denier, with opposite orientations around the core and wire for near complete coverage or greater cut resistance. Alternatively, instead of wrapping each winding in close proximity, it is possible to avoid the use of a fourth nylon or polyester.

Another preferred yarn E using the present invention is shown in FIG. 600 denier fiberglass, E-glass,
Alternatively, a first and second wrapping 58 of a 750 denier liquid crystal polymer fiber, each having a tensile strength of less than 10 grams per denier, such as Vectran M, around a core 60 composed of S-glass, preferably filament. , 59, with each winding in close proximity so that the first wrapping covers most of the core and the second wrapping covers most of the first wrapping, and a further 400
Each roll of denier nylon fiber or polyester fiber is wound close to each other.

Yet another preferred yarn F using the present invention is shown in FIG. 5, which yarn is continuous over the core portion 70 and each of the foregoing, in the opposite directions. Three synthetic fiber windings 72,74 wrapped around
It is composed of 76. Since each successive wrapping 74,76 is in the opposite direction to the previous one, it balances the force on the wrapping, prevents the thread from unnaturally twisting or getting entangled, and wrapping it over the core 70. Helps to be fixed to. The core 70 has four filaments 78 of 200 denier liquid crystal polymer fiber with a tensile strength of less than 10 grams, such as Vectran M. In another preferred embodiment of similar construction, the core is composed of about 1 to 50 filaments each having a denier number of about 4 to 500, with a total denier number of 200 to The range is 1500. With a relatively small number of filaments with a relatively high denier number, preferably at least 20 denier each, the core behaves like a filament and the liquid crystal polymer acts like a steel wire, whereby Eliminates the need for wires, such as the wire shown in Figure 1, and is less malleable, and therefore cut, as is required to prevent the core wire from breaking without the use of separate strips. It enables high strength synthetic fibers with high resistance. Wrapping 72 is a strip of 440 denier liquid crystal polymer fiber with a tensile strength of less than 10 grams per denier, such as Vectran M, wrapped around the core at a rate of 8-10 turns per inch (2.54 centimeters). The wrappings 74, 76 are each wound with 440 denier nylon at a rate of 8-12 turns per inch (2.54 cm), but polyester of that denier number may be used.

Another preferred yarn G using the present invention is shown in FIG. 6 and comprises a core portion 80 composed of 80 to 440 or 220 denier multifilament polyester fibers, opposite the periphery of the core 80. Consists of two similar wraps 82, 84 wound in different directions, each 70 denier multifilament nylon fiber, wrapped at a rate of 6 turns per inch (2.54 centimeters) Bundling filaments. The third wrapping 86 has a diameter of 0.0016 inches (0.00406
Centimeters), a single strand of fully annealed stainless steel wrapped at equal intervals of 8 turns per inch. The fourth lap 88 is
400 with tensile strength less than 10 grams, such as Vectran M4
A denier liquid crystal polymer fiber is wound in close proximity to each other in the direction opposite the wire direction, almost covering the third wrapping.
Fifth wrap 90 is 1300 microdenier polyester, with each wrap wound in close proximity in the opposite direction of the fourth wrap, almost completely covering the fourth wrap. The final diameter of this yarn is 0.020- to facilitate machine knitting on conventional knitting machines.
In the range of 0.030 inch (0.0507-0.0762 cm), preferably 0.025 inch (0.0635 cm)
Is less than. Microdenier polyester outer wrapping provides a soft and comfortable feel, easy to wash, attractive and wearable.

Although specific denier numbers and other characteristics of the preferred embodiment have been described, other numbers can be specified within reasonable limits to make the yarn resistant to beneficial cuts. . The specific numerical values specified, of course, lead to deviations in the cut resistance, flexibility, weight and thickness of the thread and of the fibers that are knitted from it, and the cost.
Normal strength liquid crystal polymer fibers such as Vectran M have a denier in the range of 200 to 3000 when used as a yarn core or wrapping using the present invention, and more typically from 200 to 1500. It is assumed to have a denier number of. The nylon or polyester used as the outer wrapping of the yarns of the embodiments of the present invention have a denier number in the range of 200 to 2000, more typically 200 to 1500. When synthetic fibers such as nylon or polyester fibers are used as the inner wrapping for bundling core fibers, it has a denier number in the range of 50 to 400, more typically 50 to 120. The cut resistance of a thread containing a metallic wire is determined in part by the amount of metallic wire in the thread, and the flexibility is in part a function of the diameter of the metallic wire. When increased cut resistance is required, the use of multiple metal strips is more advantageous in terms of flexibility than the use of one larger strip. Other types of metallic wires such as aluminum, copper, bronze, or steel can also be used for special purposes. Stainless steel wires used as cores or wrappings have diameters in the range of 0.001 to 0.010 inches (0.00254-0.0254 centimeters), more typically 0.001 to 0.006 inches (0.00254 to 0.01524 centimeters) . The various wrappings around the core are wrapped at a rate of 2 to 20 turns per inch (2.54 centimeters).
Preferably, the stainless steel wrapping has 2 to 12 turns per inch (2.54 cm), more preferably 4 to 12 turns, and the core bundling wrapping is inch (2.54 cm). It has 2 to 20 turns, more preferably about 4 to 20 turns, and a normal strength liquid crystal polymer fiber wrapping is inches (2.54 centimeters).
There are usually 8 to 12 turns per coat, and the coating wrapping can be numbered as needed to allow adequate coverage with each roll in close proximity, but usually 8 to 12 turns. It is a range.
