Definitions

  • the present disclosure relates to a technical field of a membranous body.
  • Membranous bodies configured with super fiber have been proposed as this type of membranous bodies (see Japanese Unexamined Patent Application Publication No. 2007-063710 and Japanese Unexamined Patent Application Publication No. 2021-070788 ).
  • the present disclosure provides a membranous body having high strength.
  • An aspect of the present disclosure is a membranous body.
  • the membranous body includes a super fiber layer configured with super fiber, and resin solvent layers that are in contact with the super fiber layer and formed so as to interpose the super fiber layer therebetween.
  • the super fiber layer has been subjected to at least one of a deoiling treatment and a hydrophilic treatment.
  • the super fiber layer may have at least two threads out of a first thread, a second thread, and a third thread.
  • the first thread may be a thread that extends in a first direction and is formed to include the super fiber.
  • the second thread may be a thread that extends in a second direction different from the first direction and is formed to include the super fiber.
  • the third thread may be a thread that extends in a third direction different from the first direction and the second direction and is formed to include the super fiber.
  • the super fiber layer 11 has a plurality of threads 11a extending in a first direction, and a plurality of threads 11b extending in a second direction different from the first direction.
  • the plurality of threads 11a and 11b are threads that are formed to include super fiber.
  • the threads 11a and 11b are intertwined with each other such that fluctuation of the relative positions between the threads 11a and 11b is restrained.
  • a woven fabric using super fiber threads may be formed by intertwining the threads 11a and 11b.
  • the super fiber layer 11 may be configured by a woven fabric using the super fiber threads. Examples of the woven fabric include plain weave, twill weave, and satin weave.
  • the method of manufacturing the membranous body 10 includes a weaving step (step S101), a refining step (step S102), and a resin processing step (step S103).
  • FIG. 3 is a flowchart showing a main part of the method of manufacturing the membranous body 10. Therefore, one or more other steps may be present before the weaving step. Similarly, one or more other steps may be present after the resin processing step.
  • a resin solvent is coated on the surface of the super fiber layer 11 from which oil agent has been washed away (i.e., deoiled) in the refining step.
  • the resin solvent layers 12 and 13 are formed by the resin solvent coated on the surface of the super fiber layer 11.
  • the inside of the inflatable tube 1a may be filled with air.
  • the internal pressure of the inflatable tube 1a is higher than atmospheric pressure.
  • a relatively strong force is applied to at least one of the adhered portion and sewn portion of the inflatable tube 1a.
  • the membranous body 10 is required to be relatively high, for example, in creep resistance and slippage resistance.
  • the inflatable kite 1 may crash.
  • the membranous body 10 is required to have a relatively high puncture strength such that the inflatable kite 1 is prevented from being damaged when the inflatable kite 1 crashes.
  • the membranous body 10 as examples has a super fiber layer 11 as a woven fabric using super fiber threads.
  • the resin solvent layers 12 and 13 are formed to contain polyamide-imide.
  • the mass of the membranous body 10 as the examples is 45 to 55 g/m 2 . Note that the mass of the membranous body 10 as the examples takes into account the variation in mass of a plurality of examples.
  • the membranous body 210 includes a fiber layer 211 formed by laminating one layer including a plurality of threads extending in one direction and another layer including a plurality of threads extending in another direction different from the one direction, and resin film layers 212 and 213 that interpose the fiber layer 211 therebetween.
  • the fiber layer 211 is formed by using super fiber threads.
  • the resin film layers 212 and 213 are formed to contain PET (polyethylene terephthalate).
  • the mass of the membranous body 210 as the comparative example 1 is 73 g/m 2 .
  • the membranous body 220 includes a fiber layer 221 as a woven fabric that is woven using threads extending in one direction and threads extending in another direction different from the one direction, and resin film layers 222 and 223 that interpose the fiber layer 221 therebetween.
  • the fiber layer 221 is formed by using super fiber threads.
  • the resin film layers 222 and 223 are formed to contain PET.
  • the mass of the membranous body 210 as the comparative example 2 is 82 g/m 2 .
  • FIG 7 An example of a creep test result is shown in FIG 7 .
  • the membranous body 210 as the comparative example 1 stretched a little over 15 mm in about 8.7 hours, and then broke.
  • the membranous body 220 as the comparative example 2 stretched a little over 40 mm in about 35 hours, and then broke.
  • the membranous body 10 as the example stretched about 45 mm in about 110 hours, and then broke. From this result, it can be said that the membranous body 10 has higher creep resistance than the membranous bodies 210 and 220.
  • FIG. 9 An example of a sewing slippage test result is shown in FIG. 9 .
  • the sewing strength shown in FIG. 9 is a value obtained by dividing the strength measured in the test by the square meter mass (g/m 2 ) of the membranous body. In other words, the sewing strength shown in FIG. 9 indicates the strength per unit mass.
  • the membranous body 10 has a sewing strength of 30 to 44 N/gsm when the tensile stroke is 7.5 to 12.5 mm. Comparing the maximum sewing strength values of the membranous body 10 as the example, the membranous body 210 as the comparative example 1, and the membranous body 220 as the comparative example 2, it can be said that the membranous body 10 is about 3 times the strength of the membranous body 210, and the membranous body 10 is about 1.7 times the strength of the membranous body 220.
  • the membranous body 10 has higher slippage resistance than the membranous bodies 210 and 220.
  • the sewing strength may be referred to as a tensile load.
  • the unit [gsm] means [g/m 2 ].
  • FIG. 11 An example of a tear test result is shown in FIG. 11 .
  • the sewing tear strength shown in FIG. 11 is a value obtained by dividing the strength measured in the test by the square meter mass (g/m 2 ) of the membranous body like the sewing strength shown in FIG. 9 . In other words, the sewing tear strength shown in FIG. 11 indicates the strength per unit mass.
  • FIG. 13 showing the relation between the mass and tensile strength of the membranous body.
  • the tensile strength when the mass of the membranous body is taken into consideration is indicated by gradients of a solid line, a dashed line, and a dotted line shown in FIG. 13 .
  • the membranous body 10 as the example has a lighter mass and a higher tensile strength than the membranous body 210 as the comparative example 1 and the membranous body 220 as the comparative example 2.
  • the membranous body 10 is a light and strong membranous body.
  • the membranous body 10 is not limited to membranous bodies having a tensile strength of 51 to 64 N/mm and a mass of 45 to 55 g/m 2 .
  • the super fiber has a relatively low affinity for water. Therefore, when the resin solvent is coated on the super fiber layer 11 without taking any measure, the adhesive strength between the super fiber layer 11 and the resin solvent becomes relatively low.
  • the super fiber layer 11 is subjected to at least one of a deoiling treatment and a hydrophilic treatment. Therefore, according to the present embodiment, the adhesive strength between the super fiber layer 11 and the resin solvent can be enhanced. As a result, the super fiber layer 11 and the resin are restrained from peeling off each other, so that it is possible to enhance the strength of the membranous body 10. In other words, according to the present embodiment, it is possible to provide a membranous body 10 having high strength.
  • the resin solvent makes it difficult for the relative positional relation between the threads constituting the super fiber layer 11 to change. For example, it is possible to restrain occurrence of fiber slippage of the super fiber layer 11 caused by the sewing threads. Therefore, according to the present embodiment, the sewing strength of the membranous body 10 can be enhanced.
  • the super fiber layer 11 may be a woven or knitted fabric of super fiber threads.
  • the super fiber layer 11 may be formed by binding a plurality of fiber layers with at least one of sewing thread and melt thread. Such a configuration makes it difficult for the relative positional relation between the threads constituting the super fiber layer 11 to change. In this case, the sewing strength of the membranous body 10 can be enhanced, for example.
  • the membranous body 10 is relatively high, for example, in creep resistance, slippage resistance, and puncture strength. Therefore, it can be said that the membranous body 10 is suitable as a material for the inflatable kite 1.
  • the membranous body 10 is lighter than other membranous bodies having equivalent strength (for example, the membranous bodies 210 and 220). Therefore, when the membranous body 10 is used to manufacture the inflatable kite 1, it can make enhancement in strength and reduction in weight compatible with each other for the inflatable kite 1.
  • a membranous body includes a super fiber layer configured with super fiber, and resin solvent layers that are in contact with the super fiber layer and formed so as to interpose the super fiber layer therebetween, wherein the super fiber layer has been subjected to at least one of a deoiling treatment and a hydrophilic treatment.
  • resin solvent constituting the resin solvent layers may be coated on the super fiber layer.
  • the resin solvent may include a super engineering plastic.
  • the super fiber layer may have at least two threads out of a thread that extends in a first direction and is formed to include the super fiber, a second thread that extends in a second direction different from the first direction and is formed to include the super fiber, and a third thread that extends in a third direction different from the first direction and the second direction and is formed to include the super fiber.
  • the at least two threads may be intertwined with each other such that fluctuation of relative positions between the at least two threads is restrained, or the at least two threads may be bound by at least one of a machine sewing thread and a melt thread such that the fluctuation of the relative positions between the at least two threads is restrained.
  • the super fiber layer may include a plurality of threads that are formed to include the super fiber and extend in one direction. Two adjacent threads out of the plurality of threads may be intertwined with each other such that fluctuation of the relative positions between the two adjacent threads is restrained.
  • the membranous body may have a tensile strength of 51 to 64 N/mm and a mass of 45 to 55 g/m 2 .
