The thickness of the reinforcing part was 1.1 mm.
  • IPA isopropyl alcohol
  • NE8811 polycarbonate polyurethane
  • the mass ratio of resin / diluent becomes 24/76.
  • a one-pack type adhesive solution having a viscosity of 300 mPa ⁇ S (25 ° C.) was prepared.
  • the same fastener chain with an element intermittent part as Example 1 was prepared, and the coating amount was 85 g / m 2 (dry weight) using a rectangular masking material having an opening area of 30 mm ⁇ 12 mm.
  • the solution of the one-part curable adhesive was impregnated and applied to the intermittent part of the element through a spray dispenser (trade name: 781-SS-46F Saneitec Co., Ltd.).
  • the coating conditions were an atomizing air pressure of 0.035 MPa and a clearance of 10 mm.
  • the thickness of the reinforcing part was 0.85 mm.
  • a fastener chain with a split-fitting insert was obtained in the same procedure as in Example 1.
  • Example 4 Two-component curable adhesive composition having a viscosity of 100 mPa ⁇ s (25 ° C.) diluted with toluene as a diluent so that the mass ratio of the same two resins / diluting solvents as in Example 1 is 51/49 A fastener-opened product was prepared in accordance with Example 1 except that the solution was prepared.

Abstract

La présente invention a trait à une chaîne de fermeture à glissière dotée d'une réunion, permettant d'augmenter la résistance de renfort de la section de fixation de réunion sans utiliser de ruban de renfort tout en préservant l'esthétique ; et à un procédé de production de la chaîne de fermeture à glissière. La chaîne de fermeture à glissière dotée de la réunion est équipée, sur les sites de fixation de la réunion (106), de sections de renfort (107a, 107b) qui sont imprégnées d'adhésifs durcissables (205, 308, 402) et durcis, et qui sont pourvues d'une résistance de mauvais alignement de 100 N min. Le procédé de production de la chaîne de fermeture à glissière dotée de la réunion inclut : une étape (A) qui consiste à préparer la chaîne de fermeture à glissière dotée d'une pluralité d'espaces entre les éléments ; une étape (B) qui consiste à attacher la réunion à chaque espace entre les éléments ; une étape (C) qui consiste à imprégner chaque espace entre les éléments, avant ou après l'étape (B), avec un adhésif durcissable qui est doté d'une viscosité allant de 100 à 2 000 mPa.s ; et une étape (D) qui consiste à durcir l'adhésif durcissable imprégné dans les espaces entre les éléments au cours de l'étape (C).
