  • the present invention relates to woven heaters which are highly flexible and sufficiently strong and have wrinklefree, uniform, and fiat surfaces.
  • an object of the present invention to eliminate the aforestated drawback as accompanied by the conventional woven heaters by providing an improved Woven heater which comprises a fabric base woven with warp and weft of electrically insulating fibrous material, electro-conductive metal wires interlaced into said fabric base in the areas adjacent respectively to the opposite side edges thereof and in the direction parallel to said side edges and heating wires each having an electrically insulating yarn Wound thereon and interlaced zigzag into said fabric base along the weft.
  • a woven heater having a woven fabric base woven with a warp consisting of an electrically insulating fiber such as cotton, synthetic fibre or glass fibre and a weft consisting of such electrically insulating material, electroconductive lead wires interlaced into said fabric base in the areas adjacent respectively to the opposite side edges of the web of said fabric base and extending in the direction of the warp, and heating wires each having an electrically insulating yarn wound thereon, said heating wires being interlaced into said fabricV zigzag along the weft in a manner that said heating wires provide a plurality of separate unit heating regions of a predetermined length longitudinally of said woven fabric base, said heating regions being spaced from each other by a zone which is composed only of the warp and weft yarns, said wires being partially raised above the surface of the fabric base 3,425,020 Patented Jan. 28, 1969 lCe at optional locations without interlaced into the fabric base.
  • a Woven heater which is highly fiexible and sufficiently strong and yet has Wrinkle-free, uniform and fiat surfaces
  • said woven heater comprising a woven fabric base woven with a warp consisting of an electrically insulating fibrous material such as cotton, synthetic fibre or glass fibre and a weft yarn consisting of such electrically insulating material, electro-conductive lead wires interlaced into said fabric base in the areas adjacent respectively to the opposite side edges of the web of said fabric base and extending in the direction of the warp, and heating wires each having an electrically insulating yarn Wound thereon, said heating wires being interlaced into said fabric base zigzag along the weft, whereby an outer selvage section, a lead wire section comprising said lead wires, an intermediate selvage section, a core wire selvage section and a central core wire section are formed in the order mentioned from the opposite side edges of the woven fabric base towards the center thereof in the direction of the weft, the warp density
  • the materials used in the inventive woven heater consist of a filament of synthetic fibre or glass fibre of 100 to 300d as warp, a staple of synthetic fibre or glass fibre of 2.5 to 30's/ l as weft, a stainless steel wire, for example, of SUS27 grade having a diameter of 0.05 to 0.15 mm. as heating wire and a soft copper wire of 0.1 to 0.2 mm. in diameter, for example, as lead wire.
  • the filament used as the warp is made of a synthetic fibre or glass fibre, such as Tetoron (trade name) or Vinylon (trade name), and has a size of 100 to 300 d.
  • a synthetic fibre or glass fibre such as Tetoron (trade name) or Vinylon (trade name)
  • filaments of a size smaller than 100 d. may also be weaveable, the smaller the diameter of a filament used, the higher the cost of the resultant product will be, because the filaments should be beaten more densely in order to maintain the shape of the product.
  • the use of a filament of a size greater than 300 d. will result in shrinkage of the product heating element. In this view, it is preferably to use a filament of a size ranging from 100 to 300 d.
  • the filament used as the warp is twisted from 300 to 500 turns, preferably 450 turns, per meter.
  • the twisted yarn is subjected to steam setting for 10 minutes in a steam atmosphere of 100 C. and then to sizing with a polyvinyl alcohol paste, which is followed by drying. These treatments are conducted for the purpose of preventing the yarn from fiufiing, avoiding shrinkage of the resultant fabric and hardening the yarn to prevent the fabric from losing its shape as a whole.
  • the warp is set in a weaving machine in a predetermined number.
  • the warp density in the respective sections of the fabric must be selected properly in the light of the fact that an excessively high density will render the resultant fabric unsatisfactory in respect of flexibility, while an excessively low density will render the fabric unacceptable in respect of strength.
  • the warp density in the outer selvage section is from 50 to 100 yarns per centimeter, preferably 8 yarns per 1.5 mm.
  • the width of the outer selvage section is only required to be greater than l mrn. and normally from 1.5 to 4 mm. and preferably 1.5 mm.
  • An excessively narrow width of the outer selvage section is disadvantageous in that the lead wires are pulled inwardly by the weft and cannot be held in a rectilinear state.
  • an excessively large width of the outer selvage section though not detrimental, is useless unless the section is used for securing the fabric or for other purposes. In this sense, the width of the outer selvage section is limited to about 4 mm. at widest.
  • a lead wire section in which soft copper wires serving as lead wire are interlaced with the weft in a number as determined by the amperage used.
  • the lead wires are interlaced at a density of from 30 to 60 wires per centimeter, preferably 37 wires per centimeter.
  • the width of the lead wire section is from 2 to 4 mm., preferably 2.5 mm.
  • an intermediate selvage section Inside of the lead wire section is provided an intermediate selvage section.
  • This section is provided to ensure insulation between the lead wires and heating wires and the width thereof is preferably at least 5 mm. and may be 20 or 30 mm. in some instances.
  • the warp density in this section is from 50 to 100 yarns per centimeter, which is the same as that in the outer selvage section, and preferably 25 yarns per 5 mm.
  • Warp density in this section would result in collapse of the shape of the resultant fabric and also in unsatisfactory insulation between the lead wires and the heating wires as a result of the former being pulled towards the latter, with the distance therebetween reduced.
  • an excessively high warp density in this section would result in hardening of said section causing a wavy shape of the resultant fabric and thus the appearance of the product heating element is spoiled.
  • a core wire selvage section is provided inwardly of and adjacent to the intermediate selvage section.
  • This section is provided for the purpose of imparting a portion of the fabric where the heating wires are turned back during the heating wire interlacing operation, with a strength capable of withstanding the tension of said heating Wire.
  • the width of this section is from 3 to mm., preferably 3 mm., while the warp density thereof is from 50 to 100 yarns per centimeter and preferably 60 yarns per centimeter which is sufficient to achieve the purpose described. An excessively low warp density in this section will result in collapse of the shape of the fabric being woven.
  • the warp density in this section may be as low as from 10 to 30 yarns per centimeter and preferably yarns per centimeter. It is only necessary that the warp yarns at a selected density in this section will not cause loosening of the structure of the woven fabric.
  • the weft as described previously is made of a synthetic fibre or glass bre alike the warp.
  • the yarn consists of a staple which is formed by doubling and twisting a short libre.
  • the staple is sized with polyvinyl alcohol and dried at 65 C. for 10 hours. The sizing is performed for the purpose of avoiding shrinkage of the resultant fabric and also hardening the fibre so as to prevent collapse of the .shape of the resultant woven fabric as a whole.
  • the size of the weft is determined by the pitch at which the heating Wire is interlaced zigzag and is normally in the range from 10 to 20s.
  • a suitable weft density can be determined by the pitc'h at which the heating wire is interlaced zigzag. For instance, upon considering the satisfactory insulation between adjacent heating wires, the maximum density oi the heating wires to be interlaced is 12 wires per centimeter.
  • the weft yarn is to be arranged alternatively with the heating wire and the overall density of the heating wires and weft yarns will be 25 wires and yarns per centimeter.
  • stainless steel of grades up to SUS 27 and of a diameter up to 0.05 to 0.15 mm. are weavable.
  • a difficulty is encountered in that the heating wire, during the interlacing operation, is broken due to a frictional heat. This difficulty may be avoided by winding a yarn on the heating wire.
  • a staple same as that used for the weft yarn is used.
  • the size of the yarn is essentially determined by the thickness of the heating wire used.
  • a yarn of 15 to 30s is used for a heating wire of 0.1 mm. in diameter and a yarn of 8 to 15s is used for a heating wire of 0.15 mm. in diameter.
  • the yarn Before winding on the heating wire, the yarn is twisted in the direction of Z by 400 to 500 turns per meter.
  • This twisting operation is necessary because normally the staple in its initial state is already twisted in the direction of Z by about 400 turns per meter, so that, if the staple is wound on the heating wire as such, the staple is twisted in the direction of S, that means that the twist originally possessed by the staple is untwisted. If the staple is in untwisted state, an excessive flung is caused during weaving operation and, in some instance, may even be decomposed to such an extent that it is no longer weavable. It is for this reason that the staple is twisted by 400 to 500 turns per meter in the direction of Z before it is wound on the heating wire. Under this state, as will be appreciated, the yarn is twisted by 800 to 900 turns per meter in the direction of Z, including the twist originally imparted to said yarn.
  • the weft yarns and the heating wires are disposed one adjacent to the other alternatively and each of the lead wires extends over and beneath alternatively each one of the successive weft yarns and heating wires thus disposed.
  • the lead wires extend in such manner that each of them runs over two or three weft yarns and in turn beneath the following two or three weft yarns and this continues until the next projection of the heating wires is reached.
  • the heating fabric woven into the structure described above is .applied with an electrically-conductive paint, eg. silver paint, at portions where the lead wires Contact the heating wire, in order to ensure satisfactory electrical contact therebetween.
  • an electrically-conductive paint eg. silver paint
  • the weft density is determined by the diameter of the heating wire to be interlaced and the size of the yarn to be used as the weft.
  • the maximum density of the heating wires is l2 wires per centimeter, because the density higher than that will result in undesirably less flexibility of the resultant heating fabric.
  • Between the adjacent heating wires is disposed at least one weft. From the standpoint of flexibility and others of the resultant heating fabric, the overall density of the heating wires and weft yarns is preferably not higher than 25 wires and yarns per centimeter.
  • the heating wire lhaving the yarn wound thereon is interlaced into the fabric zigzag along the -weft in such a manner that it forms a plurality of separate unit heating regions of a predetermined length, which heating regions are spaced from each other by a zone of fabric which is composed solely of the insulating warp and weft; that the lead wires are partially raised above the surfaces of the woven fabric at optional locations without being interlaced into the fabric; and that the turns of the zigzag heating wire are partially interlaced with or wound on the lead wires on both sides of said zigzag heating Wire.
  • FIGURE l is a diagrammatic plan view of a woven heater according to an embodiment of the present invention and FIGURE 2 is a fragmentary plan view in enlargement of the woven heater shown in FIGURE 1.
  • a heating woven fabric 5 which is woven with a warp 1 consisting of a 240 d. filament of Vinylon (trade name) and a weft 3 consisting of a 20s/1 staple of Vinylon and in which lead wires, 2, 2' consisting of a soft copper wire of 0.18 mm. in diameter and heating wires 4 consisting of .a stainless steel wire of SUS 27 grade and of 0.1 mm. in diameter are interlaced, said heating wire ⁇ 4 having a Vinylon yarn 4 wound thereon at a density of 47() turns per meter.
  • the heating woven fabric 5 is composed of opposite outer selvage sections 6 of 2 mm.
  • the heating wire 4 is interlaced in the fabric at a density of 11 wires per centimeter :and each yweft yarn 3 is disposed between adjacent heating wires 4 and exterior of the outermost heating wires 4, so that the overall density of the heating wires and the weft yarns is 23 wires and yarns in total per centimeter.
  • the heating wires 4 are interlaced in the fabric zigzag along the weft yarns in such a manner as to form a plurality of separate unit heating regions which are spaced from each other by a zone 12 of fabric which is composed solely of the warp and weft yarns.
  • the lead wires 2, 2. are partially raised from the surfaces of the woven fabric at optional locations by leaving that portions uninterlaced into said fabric.
  • the opposite turns of the zigzag heating Wires are partially extended outwardly as indicated :at 11, 11 for engagement with or winding ⁇ on the respec tive lead wires 2, 2 and silver paint is applied to that engaging portions.
  • the surfaces of the heat-generating fabric are insulated by embedding said fabric in a synthetic resin by impregnating it with said synthetic resin, or by covering said surfaces with cushion fabrics, such as glass mats or glass cloths, which are heat bonded under pressure to said surfaces from both sides by means of a thermosetting resin impregnated therein; or by covering said surfaces with two sheets of synthetic resin which are attached to said surfaces by means of an adhesive; or by covering said surfaces with thermoplastic resin sheets melt-bonded thereto with heat.
  • a heat-generating fabric obtained in the manner described hereinabove was coated with styrene monomer and embedded in va maleic acid phthalate polyester resin in a manner described below. Namely, two sheets of tempered glass were provided and a releasing agent, such as polyvinyl alcohol, is applied thinly to the shaping surface of one of said sheets of glass. On the layer of the releasing agent was coated a maleic acid phthalate polyester resin and then the surface of said resin coating was sprayed with styrene monomer to eliminate air bubbles present in said resin.
  • a releasing agent such as polyvinyl alcohol
  • the heat-generating fabric previously coated with styrene was placed on the jelly-like resin and then the top surface of the styrene-coated fabric was uniformly coated with a small amount of maleic acid phthalate polyester resin and further with styrene to deprive the resin of air bubbles. Thereafter, the other sheet of tempered glass, having a layer of jelly like maleic acid phthalate polyester resin previously formed on a surface thereof in the manner described above, was placed on the fabric with sai-d jelly-like layer facing downwardly so carefully that no air bubble may be trapped therebetween.
  • a pressure of l l g./cm.2 is continuously applied to the top glass until the resin interior of the sheets of glass presented a jelly-like state, ⁇ which was followed by heating at 60 to 80 C. for l0 to 20 minutes to thereby cure the resin. After curing, the resin was allowed to cool to about 40 C. and then the sheets of tempered glass were removed, whereupon a product plane heating element was obtained.
  • the inventive Plane heating element produced in the manner described hereinabove is advantageous in that it is free fro-m wrinkle, because, since the heating wire is interlaced partially in place of the weft yarn, it is not permitted, during the weaving operation, to be slackened as it is turned and to swerve under the swerving tendency previously imparted to said heating wire during storage on a spool.
  • inventive plane heating element is that, since the adjacent unit heating regions of a predetermined heating capacity or a predetermined length are optionally spaced from each other by a zone of fabric which is composed solely of the insulating warp and weft yarns, not only is it possible to obtain la positive insulation between the heating Wires in said unit heating regions but also each heating region can be sepanated from another easily by cutting.
