There is a problem that it is difficult to increase the manufacturing speed.

  • the adhesive resin is an olefin-based and / or a synthetic rubber-based resin.
  • the coating of the deodorant by the adhesive component can be significantly reduced. Further, since the heat required for melting the adhesive component is applied at the time of resin coating, heat is not applied after laminating, so that the production speed can be significantly increased. In addition, since heat is not applied after lamination, deterioration of dust collection performance due to heating can be suppressed. Similarly, the method for producing a deodorizing sheet of the present invention suppresses a decrease in deodorant performance due to coating of an adhesive component, increases the production rate, and suppresses a decrease in dust collection performance due to heating.

If it is lower than 100 ° C., the heat resistance in bonding the finished deodorizing sheet becomes low, and if it is higher than 180 ° C., a high temperature resin is applied to the sheet, which causes problems such as shrinkage and deformation of the sheet.
