  • the second embodiment of this invention relates to cut resistant yarns and their use in protective garments.
  • protective garments There are many applications for such protective garments. Meat processing employees exposed to sharp knives require such garments. Metal and glass handlers who must be 20 protected from sharp edges during the handling of materials may use such protective garments. Medical personnel who are exposed to scalpels and other sharp insturments may obtain protection through the use of such garments.
  • U. S. Pat. No. 3,883,898 suggests that an aramid fiber, such as "Kevlar", be used in cut resistant gloves that are worn by meat processors.

  • the use of metal wire in a cut resistant yarn makes the yarn electrically conductive. This means that a garment made with such a yarn cannot be used in contact with high-voltage electrical equipment.
  • the use of a nylon monofilament, instead of metal wire, in a cut resistant yarn removes the problem of electrical conductivity.
  • the use of nylon monofilament results in a less cut resistant yarn. The nylon is much more easily cut by very sharp edges than is metal wire. Therefore, the yarn as a whole is more easily cut.

Cut Resistant Yarn (Second Embodiment)
  • the yarn of the second embodiment of the present invention is comprised of at least two fibrous materials, with at least one being flexible and cut resistanct and at least another which must have a high level of hardness.
  • the desirability of using this particular combination of materials has been made apparent through careful observation of the cutting action of sharp edges against various fibrous materials.
  • the present invention requires that at least one of the fibrous materials in the yarn be a flexible, inherently cut resistant material such as, but not limited to, an aramid fiber or ECPE fiber. While materials such as aramid fibers and ECPE fibers are cut resistant, even they can be cut through with relatively moderate force if an extremely sharp edge is used during cutting and if the edge is pulled across the material while the cutting force is being applied. In the course of developing the present invention it was discovered that adding a hard fibrous material to the flexible, inherently cut resistant material dramatically increased the cut resistance of the yarn. It was discovered that the hard material dulled the cutting edge during the cutting process, and as a result made it more difficult for the edge to cut through.
  • any nonmetallic, hard fibrous material may be used. Glass fibers and ceramic fibers are common examples of such materials.
  • hard is any material that has a hardness level such that it is capable of significantly reducing the sharpness of a cutting edge.
  • the form that the hard fibrous material takes can be quite varied.
  • the hard fibrous material can be of uniform composition and continuous in length, such as a continuous filament glass fiber. It may be of noncontinuous length, such as chopped glass fiber. It may be nonuniform in composition.
  • the fibrous material may be composed of an organic fiber coated with layer of ceramic material. Another example would be that of an organic fiber which is impregnated with ceramic particles or fibrils.
  • the brittleness of the hard materials used is not a major concern.
  • the glass or ceramic fibers that would normally be used in this invention are extremely small in diameter. If larger diameter is required, a coated or impregnated fiber, described above, can be used. As a result, these hard materials are still very flexible and can be bent around a very small radius without breaking. It is preferred that the hard fibrous material be placed in the core of the composite yarn. In this manner, the hard material is exposed to the least stress during bending of the yarn. In addition, by placing the hard material in the core of the yarn, the outer layers of flexible, inherently cut resistant material help protect the more brittle core material.
  • the hard fibrous material be coated with a continuous layer of elastic material.
  • This coating has several important functions. If the hard material is a multifilament fiber, the coating holds the fiber bundle together and helps - protect it from stresses that develop during handling of this fiber before it is placed in the composite yarn. The coating may provide a physical barrier to provide chemical protection for the hard material. Additionally, if the hard material is broken during use, the coating will trap the material so that it will not leave the yarn structure.
  • a cut testing apparatus useful to measure the cut resistance of fibers and yarns of this invention is described in copending U.S. Serial No. 223,596 filed 7/25/88 hereby incorporated by reference, i ⁇ i toto. For purposes of this invention "the cut testing apparatus" shall mean the above-described apparatus.
  • the jacket can be formed either separately and placed on the core of rope or formed around the core during one of the manufacturing steps.
  • Comparative Sample 1 was a Kevlar stranded rope jacketed with fabric braided from comparative yarn C.
  • Comparative Sample 2 was an ultrahigh molecular weight high strength polyethylene (Spectra® 900) fiber stranded rope jacketed with fabric braided from comparative yarn C.
  • Example of this invention Sample 3 was the above-described ultrahigh molecular weight polyethylene (Spectra®) fiber strand rope, surrounded with a jacket braided from Yarn A.
  • Spectra 900 fiber has a denier of 1200, 118 filaments per strand typically, tensile strength of 2.6 GPa, modulus of 120 GPa and elongation of 3.5 percent.
  • the three jacketed ropes were tested by a guillotine test.
  • the rope was held in a fixture so its movement was restricted. Clamps prevented it from moving along its axis and the rope was inside two pieces of pipe to prevent it from deflecting during cutting. The two pieces of pipe were separated - very slightly where the blade made the cut. The maximum force needed to completely sever the rope was measured.
  • the cut damage test the rope was laid on a wooden surface without further restraint. A blade was then forced into the rope at 250 pounds (113.6 kg) of force. The damaged ropes were tested for retained strengths In both tests a new Stanley blade no. 1992 was used for each sample tested. The results of the tests are given below.
  • Sample 3 was a 3, -inch (0.6 cm) stranded rope jacketed with a braided fabric of yarn A.
  • each sample rope was bent in a 90 degree angle over a 10-inch (25.3 cm) diameter abrasive wheel.
  • the ropes were loaded with 180 pounds (81.8 kg) and reciprocated through a 3-inch (7.6 cm) stroke as the abrasive wheel rotated at 3 rpm.
  • the test ended when the jacket wore through.
  • the number of strokes (cycles) for each was 8 for Comparative Sample 2 and 80 for Sample 3.
  • Example 3 - Braided Rope First Embodiment
  • Comparative Sample 4 rope was braided from the high strength, ultrahigh molecular weight polyethylene yarn described above and the jacket was braided from a polyester yarn of 1000 denier, 192 ⁇ filaments per end, 1.05 GPa tensile strength, 15.9 GPa modulus, and 15 percent elongation.
  • Sample 5 rope was braided from Kevlar yarn of
  • Sample 7 rope was identical to Sample 6 except more tension was applied during braiding of the rope to create a "hard” rope. A fixed load was applied to the rope as in
  • Example 1 When the ropes were taut under the knife, there was little difference in cut resistance between ropes. In the cut damage test, the results are below.
  • test lines had cores composed of parallel synthetic bers. Six lines had cores of polyester fiber. Three had cores of Kevlar fiber, and one had a core of Spectra® 900.
  • Resistance to penetration by sharp points was measured in two ways: 1) using the Shore D scale of a Durometer (ASTM method #2240), and by stabbing with a simulated shark tooth of hardened steel as described in the "Deep-Sea Lines Fishbite Manual” (Prindle & Walden, 1975). Each data point from the penetration tests is an average of five measurements of the force required to pierce the surface of a line to a standard distance.
  • Table III illustrates data obtained with the Durometer and it is evident that by this test none of the lines submitted was equal to either of the armored reference lines i.e. Acetal Copolymer (AC) or Nylon (N), when tested without tension.
  • the best of the test lines were #1 armored with 47 mils of ionomer, #6 armored with 76 mils of ionomer, and #10 armored with 114 mils of polyester. The rest were below a level which would seem to warrant further consideration. However, some mention should be given to the samples armored with braids. They are #7 armored with polyolefin and aluminum braid, #8 armored with Kevlar braid, and #9 armored with polyurethane and a metal braid.
  • Copolymer (AC) was again the most resistant, requiring 63 lbs. to pierce. /Second place went to #10, armored with 114 mils of polyester. It had 70% the resistance of the acetal copolymer reference line and out performed the Nylon 6/6 (N) reference standard. Next in line was item #9, armored with polyurethane and braid. The next few spots went to items #1, 5, 6, and 7 with only 71% the stab resistance of the marginally acceptable nylon 6/6 covered line. Tension produced marked changes in the ratings.
  • #1 spot went to item #9, urethane and braid armor, which rose from 35 lbs. resistance to 58 lbs. Under tension, it was substantially equal to acetal copolymer in the unstressed condition. With tension, there were 3 lines closely competitive for second place at a level of about 38 lbs. which is the same as the acetal copolymer reference line, and better than the nylon 6/6 armored -line at 31 lbs. All three braid-covered lines showed an increase in resistance to stabbing when a tensile load was applied.
  • test lines Four of the test lines were more resistant to cutting than the two reference lines, both in the relaxed and in the stressed conditions.
  • Kevlar rope with polyolefin and aluminum braid armor was composed of 35. mils of polyolefin over the Kevlar fiber plus a layer of aluminum braid plus 41 mils of polyolefin. It was a good handling line albeit a bit stiffer than some others.
  • the Durometer test was below that of nylon 6/6.
  • Stab test on the relaxed rope was below that of nylon 6/6 but when the line was loaded it became much more resistant to stabbing and was about equal to acetal copolymer. In the cut test, it ranked third when unstressed and when stressed, it was superior to both of the reference lines. This is a good line and worth a test at sea.
  • Sample A was a knitted glove made from a ECPE fiber, Spectra 1000. The glove was knitted on a 7 gauge Shima Seiki glove knitting machine. The yarn used to produce the glove was composed of 2 ends of 1200 denier fiber, with 1 turn per inch twist in each fiber end, resulting in a total yarn denier of 2400. The glove fabric was approximately 0.045 inches thick, with a weight of approximately 13.8 oz. per sq. yd.
  • Sample B was a woven fabric made using glass fiber (E-glass) .
  • the fabric was a satin weave 57x54, using 595 denier untwisted glass fiber, with a thickness of 0.009 inches and a weight of 8.9 oz. per sq. yd.
  • Sample C was a knitted glove made from the combination of ECPE fibers (Spectra 1000) and a glass fiber (E-glass).
  • the yarn used in the glove was constructed by placing a.595 denier glass fiber and a 650 denier ECPE fiber in the yarn core, with no twist, and wrapping the core in one direction with 650 denier ECPE fiber and then wrapping in the other direction with another 650 denier ECPE fiber.
  • the composite yarn denier was 2900.
  • the glove was knitted on a 7 gauge Shima Seiki glove knitting machine.
  • the glove fabric was approximately 0.055 inches thick, with a weight of approximately 18 oz. per sq. yd.
  • the test used to measure the cut resistance of the mentioned samples is described in copending U.S. Serial No. 223,596.
  • the test involves repeatedly contacting a sample with a sharp edge until the sample is penetrated by the cutting edge.
  • the higher the number of cutting cycles (contacts) required to penetrate the sample the higher the reported cut resistance of the sample.
  • the following conditions were used: 135 grams cutting weight, mandrel speed of 52 rpm, rotating steel'mandrel diameter of 19 mm, cutting blade drop height of 9 mm, use of a single-edged industrial razor blade (Red Devil brand) for cutting, cutting arm distance from pivot point to center of blade being 6 inches.
  • the two glove fabrics were tested by cutting fingers from the gloves and mounting the finger on the tester mandrel. The fingers were held on the mandrel with a band clamp placed over the cut end of the fingers.
  • the woven fabric sample (sample B) was tested by cutting a 2 by 2 inch piece from the fabric, wrapping the sample around the tester mandrel and holding it on the mandrel with adhesive tape. The woven fabric was mounted so that the cutting blade did not contact the sample where the mounted fabric edges overlapped. The cutting cycles reported are an average of multiple tests. For each test a new, unused razor blade was used so that the sharpness of the cutting edge was the same for each test.
  • a woven glass fabric was used because of its availability. It would have been desireable to test a knitted glass fabric as well. However, glass fibers are difficult to knit due to their brittleness and such fabrics were not readily available. It is not expected that a knitted glass fabric would have a significantly different level of cut resistance as compared to a woven glass fabric.
