  • Flame-retardant protective gloves are a prerequisite for certain professions in order to be able to handle certain occupations that are part of the performance of duties with sufficient security. Examples of such occupational groups are fire fighters, the military, police, ambulance personnel etc. Flameproof gloves are generally known.
  • a protective glove is known from SE 458 254 .
  • the protective glove has the shape of a finger glove.
  • the glove consists mainly of leather whose inner surface has been provided with a plastic coating.
  • the glove is provided with a lining of refractory and heat-insulating material.
  • Such a protective glove becomes relatively awkward due to the plastic-coated leather becoming relatively rigid.
  • the combination of materials makes it difficult to wash and decontaminate.
  • a similar design is known from DE 10111143 .
  • a flame-retardant protective glove is obtained which in a surprising way at the same time provides good comfort, good protection, good grip ability, good wear resistance and which may securely be washed and decontaminated.
  • Figs. 1 and 2 shows a preferred embodiment of a glove according to the invention from above and below, mainly intended for fire fighters and similar use.
  • the glove is partly made of elastic material, which makes the glove easy to put on and take off and provides good comfort.
  • the inventors have arrived at a preferred combination of layers for use in the palm side 2 of an elastic multilayer material, which well meets these complex requirements for fire fighter gloves and similar uses, e.g. meeting the requirements of European standards 420,659 and 388.
  • FIG. 1 and Fig. 2 there are shown two perspective views of an exemplary fire figter glove in accordance with the invention.
  • the glove comprises a palm side 2, a backside 3, an outer side 4 and a thumb side 5.
  • the thumb is marked with reference sign 6 and the remaining fingers are given reference number 7. Further, there is shown that the glove also includes a cuff 8.
  • the glove basically includes three different materials in the outer shell. There is a first material M1 that is used for the backside 3 in the form of a relatively large backside piece 30. There is also a part 60 made in the first material M1 that is used as one of a plurality of pieces for the thumb 6. Further, the first material M1 may also be used for the cuff 8.
  • the second material M2 is used for the major part 20 of the palm side 2 and also for an inner piece 61 for the thumb 6.
  • the third material M3 is used in the form of a first side piece 50 on the thumb side 5 of the glove and a second side piece 40 on the outer side 4 of the glove. Furthermore, the third material M3 is used for a plurality of finger side pieces 70, 71, 72, 73. Finally, the third material M3 is used for a third piece 63 of the thumb 6.
  • a fourth material 83 for the cuff edge and for the transition zone between the cuff and the glove part.
  • a fourth material 83 for the cuff edge and for the transition zone between the cuff and the glove part.
  • an eyelet device 81 along the palm side of the cuff 8 to assist in putting the glove on.
  • Fig. 3 there is shown a cross-sectional schematic view of the glove according to Figs. 1 and 2 along line A-A. It is shown that the glove basically comprises an outer protective shell and an inner protective insert 9.
  • the insert 9 is fixated to the outer glove shell by means of seams (not shown) at the fingertip points and also a resilient seam/s 95, preferably Nomex thread, corresponding to a position adjacent the wrist.
  • Fig. 4 there is shown a more detailed cross-sectional view along lines B-B in Fig. 3 , in order to in more detail explain the different materials used for a glove according to the invention.
  • the inset 9 may be produced in a large variety of different materials in accordance with the invention, depending on different needs for different uses of a glove according to the invention.
  • the glove is intended for firefighting purposes and provided with preferred combination of materials, without any limitation to such a combination, wherein the combination of materials of the glove 1 may provide protection against harmful biological agents, cuts by hand-held chainsaws, high-pressure jets and bullet wounds or knife stabs.
  • first shell material M1 comprising an outer protective layer part 30, se Fig. 5 , comprising a basic protective layer 30B and coating 30A.
  • first shell material M1 comprises a basic protective layer 30B including 70-80% aramide fibers, suitably Para-aramide fibres, and 20-30% other strong fibres, e.g. polybenzimidazole fibres, preferably in the form of a half cardigan stitch-knitted fabric.
  • aramide fibers are para Aramide fibers.
  • the coating 30A preferably comprises silicone.
  • the weight being in the range of 300 - 600 g/m 2 , preferably at least 400 g/m 2 and a thickness of between 0,8 to 1,8 mm, preferably larger than 1 mm and maximum 1,5 mm.
  • the elongation at break ⁇ is of at least 50% in all directions, preferably at least 70% in all directions.
  • the first multilayer material M1 has a larger elongation at break ⁇ W in a width wise direction W than the elongation at break ⁇ F in a length wise direction W, wherein preferably ⁇ w > 1,1 - 2 ⁇ F .
  • the cuff piece 80 and a thumb piece part 61 may be made in the same material M1.
  • the outer shell of the palm side 2 of the glove comprises two parts 20, 61 made of the second material M2.
  • the large palm part 20, see Fig 5 covers most of the palm of the hand and also includes an inner part for the fingers 7.
  • a thumb piece part 61, see Fig 8 is also made of the second material M2, to provide a really good grip.
  • the second material M2 comprises a multilayer, cohesive material, having an outer coated layer 20A of a flame retardant resilient material comprising Chlorosulfonated Polyethylene and a second, base layer 20B including at least 80% aramide fibers, suitably Para-aramide fibers, preferably at least 90% Para-aramide fibers and more preferred 100% Para-aramide fibers.
  • the Aramide fibers are para Aramide fibers.
  • the second multilayer material M2 preferably is in the form of an interlock knitted fabric, which provides very good bond for the coated outer layer 20A.
  • the second multilayer material M2 has its largest elongation at break ⁇ F in a length wise direction F
  • the first multilayer material M1 has its largest elongation at break ⁇ W in a width wise direction W.
  • the third material M3 in the outer shell also comprises a multilayer, cohesive material, having an outer layer of a flame retardant material comprising Polyamide fibers and a second layer comprising aramide fibres.
  • the Aramide fibers are para Aramide fibers.
  • the third material M3 includes around 50-70 % Polyamide fibers and 30-50% Para-aramide fibers, Preferably the amount of Polyamide fibers is larger than the amount of Para-aramide fibers.
  • the third multilayer material M3 has a surfacic mass of between 300 to 800 g/m 2 , preferably 400 to 600 g/m 2 .
  • the seams between the parts are preferably made as double seams, and by the use of a sewing thread made from 90-100% spun meta aramid fiber, preferably using a vertically integrated aramid manufacturing system.
  • a membrane 90 arranged as an outer layer all around the insert 9.
  • it is a copolyamide membrane 90 that is elastic in all directions with high vapor permeability, having a melting temperature above 100 ° C, suitably up to 120° C, and a wash resistance of at least 60° C.
  • the membrane is also completely fogging-free.
  • the insert 9 at the back side 3 includes two layers 91A, 91B of a heat resistant material, preferably PAN/PES of about 120 to 200 g/m 2 .
  • a liner 92 preferably including about 50 -70% Aramid and 30-50% glass, of about 250 to 350 g/m 2 .
  • the insert 9 preferably has a larger amount of heat resistant material at the back side 3 than at the palm side 2.
  • a glove according to the invention presents a surprising combination of desired properties for a flame retardant glove, for which there has been a long felt need.
  • the invention is not limited by the above shown but can be varied within the scope of the appended claims. Those skilled in the art will recognize, for example, that the exact design of various components may be varied in many ways. Thus, it is understood, for example, that the glove also retains its basic functionality if having two or more of the fingers integrated to form a common space for two or more fingers, e.g. in the form of a thumb glove.
  • One variant is, for example, to leave only the index finger and thumb free while the little finger, ring finger and middle finger are combined in a wide finger.
  • Another variant is that only the little finger and ring finger 3 are integrated into one and the same space.
