Embodiment
[0104] The following examples show the present invention in detail and specifically. In addition, the evaluation results etc. in the Example were measured by the following method.
[0105]
[0106] Based on the composition ratio obtained by NMR analysis of the obtained resin material, it is converted into mass% based on the monomer mass ratio.
[0107]
[0108] The measurement was performed using the SMV-300RT "Mooney Viscometer" manufactured by Shimadzu Corporation.
[0109]
[0110] The measurement was performed using a light scattering particle size distribution measuring device LB-500 manufactured by Horiba Manufacturing Co., Ltd.
[0111]
[0112] For resin materials and paste-like materials, each material is applied to the release sheet in an amount to reach a dry thickness of 100±10μm, dried and cured under predetermined conditions, and then stamped into ISO 527 together with the release sheet -Dumbbell shape specified in 2-1A, as a sample piece. For sheet-like materials, the...

[0126]
[0127] Add to the stainless steel reaction vessel equipped with a mixer and a water cooling jacket:
[0128]
[0129] Keep the temperature of the water bath at 15°C under nitrogen flow and stir gently. Then, an aqueous solution of 0.3 parts by mass of potassium persulfate dissolved in 19.7 parts by mass of deionized water was dropped over 30 minutes, and after the reaction was continued for another 20 hours, 0.5 parts by mass of hydroquinone dissolved in 19.5 parts by mass of deionized water was added. In the aqueous solution, the polymerization is stopped.
[0130] Then, in order to distill off the unreacted monomer, first, the pressure in the reaction vessel is reduced, steam is further introduced, and the unreacted monomer is recovered to obtain a synthetic rubber latex (L1) composed of NBR.
[0131] Add salt and dilute sulfuric acid to the obtained latex, perform coagulation / filtration, and repeat the re-dispersion and filtration of the resin in the deionized water in 5...

[0133] Except that 40 parts by mass of styrene and 60 parts by mass of butadiene were used instead of acrylonitrile and butadiene of Production Example 1, the same operations were performed to obtain synthetic rubber resin R02. Synthetic rubber resin R02 has a nitrile group content of 0% by mass, a Mooney viscosity of 67, and an elastic modulus of 51 MPa.

Abstract
To provide a stretchable conductor sheet which is useful as a material for electrical wiring lines and electrodes for wearable electronic devices, said material having excellent durability in terms ofwashing and durability in terms of perspiration. A fabric provided with an electrode and an electrical wiring line, which are formed from a stretchable conductor sheet, is obtained by: providing a film having mold releasability with a first stretchable conductor layer which is formed from a paste material that uses carbon-based particles as a conductive filler, while using a flexible resin as a binder resin; subsequently forming a second stretchable conductor layer, while using metal-based particles as a conductive filler; laminating a hot melt adhesive layer thereon; superposing the resulting laminate on a fabric after removing unnecessary parts from the laminate by means of partial slits; and subjecting the resulting fabric to hot pressing. Since the carbon-based particles adsorb a contamination substance of the metal-based particles, oxidation degradation and sulfuration degradation of the metal-based particles is reduced, thereby improving the durability.
Description
Technical field [0001] The present invention relates to a sheet-like stretchable conductor sheet that can be laminated on a stretchable base material, and a method for forming electrical wiring used in clothing-type electronic devices and the like using these. Background technique [0002] In recent years, wearable electronic devices have been developed that aim to enable electronic devices with input and output, computing, and communication functions to be used in close proximity or in close contact with the body. As wearable electronic devices, there are known accessory-type devices such as watches, glasses, and earphones, and textile-integrated clothing-type electronic devices in which electronic functions are assembled on clothing. [0003] Electronic equipment requires electrical wiring for power supply or signal transmission. Especially for textile-integrated wearable electronic devices with stretchable clothes, the electrical wiring is also required to be stretchable. Gene...
