  • the fabric construction of protective fabric 4 is, for example, plain weave.
  • Yarns 41 are more flexible than wires 42 .
  • Yarns 41 are twisted yarns produced by twisting, for example, natural fibers or chemical fibers. It should be noted that yarns 41 may be single yarns.
  • Wires 42 have the same configuration. Specifically, wires 42 have the same diameter, length, degree of tungsten purity, etc. It should be noted that wires 42 may include a wire having at least one of the diameter, length, and degree of tungsten purity which is different from the other wires.

  • Each wire 42 that is extra fine and made of tungsten may be produced by, for example, the following method.
  • Tungsten powder having a particle diameter of 5 ⁇ m is press-molded and sintered to be a tungsten ingot.
  • the tungsten ingot is swaged into a wire by being press-forged from its periphery and extended.
  • drawing of the wire is performed using drawing dies. The drawing is performed using the drawing dies each having a different pore diameter in decreasing order of pore diameter.
  • MG is a unit that indicates a numerical value representing, in milligrams, a mass of a wire having a length of 200 mm.
  • the tensile strength of wire 42 increases as a result of performing the drawing using wire drawing dies. In other words, wire 42 is less likely to break off even when wire 42 is made extra fine, or rather increases in strength by being made extra fine.
  • yarns 41 are disposed in a sheet-like shape.
  • yarns 41 constitute sheet-like body 6 that is flexible.
  • Portions of wires 42 overlapping with yarns 41 are overlaid portions 421 that are in sheet-like body 6 and discrete. Stated differently, overlaid portions 421 are the portions of wires 42 overlapping with yarns 41 in a plan view.
  • yarns 41 and wires 42 may be weft yarns and warp yarns, respectively. Moreover, yarns 41 and wires 42 can be mixed in weft yarns, and yarns 41 and wires 42 can also be mixed in warp yarns. In the case of mixing, wires 42 should be spaced out evenly in order to achieve balanced protectiveness of protective fabric 4 as a whole.
  • protective fabric 4 is not limited to the above-described plain weave, and may be twill weave such as 2/1 twill weave and 3/1 twill weave, or satin weave etc.
  • protective fabric 4 may be produced by knitting yarns 41 and wires 42 as knitting yarns. Even when a protective fabric is a knit fabric, the knitting yarns constitute a sheet-like body, and portions of wires overlapping with yarns are overlaid portions.
  • protective fiber 4 according to Embodiment 1 includes: sheet-like body 6 that is flexible; and overlaid portions 421 that are in sheet-like body 6 and discrete. Overlaid portions 421 each include tungsten.
  • overlaid portions 421 each including tungsten are in sheet-like body 6 and discrete, overlaid portions 421 are capable of being bulletproof and stab-proof.
  • overlaid portions 421 are in sheet-like body 6 and discrete, portions exposed from overlaid portions 421 are present in sheet-like body 6 . Since these exposed portions have the flexibility of sheet-like body 6 , protective fabric 4 is flexible at the exposed portions. With this, it is possible to increase the flexibility of protective fabric 4 while maintaining the protectiveness of the same.
  • overlaid portions 421 each include tungsten, it is possible to shield radiation.
  • Piece of protective clothing 1 according to Embodiment 1 includes: protective fabric 4 ; and clothing body 2 that holds protective fabric 4 .
  • piece of protective clothing 1 includes protective fabric 4 having greater flexibility while maintaining protectiveness as above, it is also possible to increase the flexibility of protective clothing 1 while maintaining the protectiveness of the same.
  • protective fabrics 4 are layered and held, it is also possible to increase the protectiveness of piece of protective clothing 1 as a whole. It should be noted that if single protective fabric 4 does not provide sufficient protectiveness, front body 21 and back body 22 of clothing body 2 may each hold single protective fabric 4 .
  • sheet-like body 6 includes yarns 41
  • protective fabric 4 is one of a knit fabric and a woven fabric that includes yarns 41 and wires 42 each of which includes tungsten
  • overlaid portions 421 include portions of wires 42 that overlap with yarns 41 in a plan view.
  • protective fabric 4 is one of the knit fabric and the woven fabric that include yarns 41 and wires 42 each of which includes tungsten, it is possible to dispose overlaid portions 421 discretely by one of weaving and knitting using yarns 41 and wires 42 .
  • wires 42 are wire rods, it is possible to densely dispose wires 42 in one of the woven fabric and the knit fabric in whole. Accordingly, protective fabric 4 is capable of providing protectiveness as a whole.
  • wires 42 each have a diameter of at least 40 ⁇ m and at most 200 ⁇ m.
  • wires 42 each have the diameter of at least 40 ⁇ m, when wires 42 are made into protective fabric 4 , protective fabric 4 is capable of acquiring certain properties in terms of being both bulletproof and stab-proof.
  • wires 42 each have the diameter of at most 200 ⁇ m, wires 42 have greater flexibility and protective fabric 4 become more flexible.
  • Embodiment 1 describes the case in which protective fabric 4 is produced using wires 42 that are not coated, a protective fabric can be produced using coated wires.
  • FIG. 4 is a sectional view of wire 42 a according to a variation of Embodiment 1.
  • wire 42 a has a surface covered with cover layer 43 .
  • Cover layer 43 is, for example, a twisted yarn, and covers the surface of wire 42 a by twisting wire 42 a as a core. Accordingly, it is possible to make surface textures between yarns 41 and wires 42 a more alike, which allows the enhancement of the appearance of protective fabric 4 .
  • Embodiment 1 describes the case in which overlaid portions 421 made of tungsten are discrete by wires 42 and yarns 41 being woven.
  • Embodiment 2 describes a case in which overlaid portions include films. It should be noted that in what follows, the same reference signs are assigned to portions that are the same as in Embodiment 1, and descriptions thereof may be omitted.
  • FIG. 5 is a perspective view and a partially enlarged plan view of protective fabric 4 B according to Embodiment 2.
  • FIG. 6 is a fragmentary sectional view of protective fabric 4 B according to Embodiment 2. Specifically, FIG. 6 is a cross-sectional view of protective fabric 4 B taken along line VI-VI in FIG. 5 .
  • protective fabric 4 B includes sheet-like body 6 b and overlaid portions 8 .
  • Sheet-like body 6 b is a fabric body having no protectiveness. Specifically, sheet-like body 6 b is a woven fabric produced by weaving yarns 41 as warp yarns and weft yarns. It should be noted that a sheet-like body may be a knit fabric produced by knitting yarns 41 or a nonwoven fabric produced by entangling flexible fibers.
  • Overlaid portions 8 include films deposited on the surface of sheet-like body 6 b , and are made of tungsten.
  • the plan view shape of overlaid portions 8 is a regular hexagonal shape.
  • overlaid portions 8 are discretely and evenly spaced out on the surface of sheet-like body 6 b . Accordingly, interval H between adjacent ones of overlaid portions 8 is constant. Greater interval H reduces bulletproof and stab-proof levels of protective fabric 4 B as a whole. For this reason, interval H may be smaller than the diameter of a bullet head or the thickness of a blade edge. Specifically, interval H may be at most 3 mm and more preferably at most 1 mm.
  • Overlaid portions 8 are sprayed films produced by a thermal spraying technique. Specifically, the sprayed films are produced by a thermal spraying device melting or softening a tungsten material with heat, performing microparticulation of the tungsten material and accelerating the minute particles, and causing the minute particles to collide with sheet-like body 6 b . As a result, each of overlaid portions 8 includes integral-type tungsten.
  • a mask is disposed between a nozzle of the thermal spraying device and sheet-like body 6 b . The mask is provided with openings in advance, and the tungsten material passing the openings is formed into overlaid portions 8 on sheet-like body 6 b .
  • overlaid portions 8 can be collectively formed.
  • the shape of the openings of the mask determines the plan view shape of overlaid portions 8 .
  • controlling the shape of the openings of the mask allows control of the plan view shape of overlaid portions 8 .
  • the layout of the openings of the mask determines the layout of overlaid portions 8 , controlling the layout of the openings of the mask allows control of the layout of overlaid portions 8 .
  • the films to be overlaid portions 8 can be produced by a technique other than the thermal spraying technique.
  • the technique include a 3D printing technique.
  • a 3D printing technique is, for example, binder jetting in which tungsten granular materials are combined by binder being jetted, and are sintered by heat.
  • Embodiment 2 describes the case in which the plan view shape of overlaid portions 8 is the regular hexagonal shape, the plan view shape of overlaid portions may be any other shape.
  • Examples of the plan view shape of overlaid portions 8 include a polygonal shape other than a hexagon, a ring shape, an elliptical shape, and an inner shape defined by a closed curve other than these shapes.
  • overlaid portions 8 may have different plan view shapes.
  • overlaid portions 8 include films on a surface of sheet-like body 6 b.
  • overlaid portions 8 include films
  • overlaid portions 8 can be produced using, for example, a thermal spraying technique or a 3D printing technique. If overlaid portions 8 can be produced using such a technique, it is possible to enhance the degree of freedom of a plan view shape and a layout of overlaid portions 8 .
  • a layout is easily employed in which overlaid portions 8 are not disposed in a portion for which flexibility is emphasized.
  • a layout is easily employed in which overlaid portions 8 are broadly disposed in a portion for which protectiveness is emphasized.
  • a protective fabric is easily produced depending the intended use.
  • the films are sprayed films.
  • sprayed films produced by a thermal spraying technique can be used as overlaid portions 8 .
  • the thermal spraying technique is capable of collectively producing overlaid portions 8 .
  • Embodiment 2 illustrates the case in which sheet-like body 6 b is a fabric body.
  • sheet-like body 6 b may be any sheet-like body as long as the sheet-like body has flexibility.
  • Examples of the sheet-like body other than the fabric body include a resin sheet and a piece of paper.
  • Embodiments 1 and 2 describe the case in which clothing body 2 including the fabric having no protectiveness holds protective body 3 .
  • a clothing body itself can be produced using a protective fabric.
  • a protective body may be omitted from a piece of protective clothing.
  • a clothing body is produced using a protective fabric and the clothing body holds the protective body, it is possible to further increase protectiveness.
  • Embodiments 1 and 2 describe the case in which each of front body 21 and back body 22 of clothing body 2 holds protective body 3 , another portions of clothing body 2 (e.g., sleeves and a collar) may each hold a protective body.
