Equipment that performs specialized liquid processing on films.
Conducting liquid treatments such as acidic or alkaline treatments enables changes in film composition, surface modification, extraction, etc.

• Liquid manipulation skills honed through the use of textile machinery

  Since our establishment, we have been selling equipment worldwide, primarily in textile machinery.
  Materials like everyday clothing involve numerous processes using water, such as dyeing and washing.
  This technology is currently employed in high polymer films and represents ICHIKIN’s unique proprietary technology that others cannot imitate.

• Surface modification by immersion in liquid

  A process involving alkaline hydrolysis is used in saponification treatment for TAC film surface modification, and fiber separation and division for non-woven fabrics, etc.

• Extraction by immersion in liquid

  A process for extracting specific components.
  Ion exchange membranes, such as battery separator films, form pathways for ions known as micropores by extracting and washing solvents contained in raw material films.

• Solidification by immersion in liquid

  Utilizes the property of solidifying when immersed in liquid.
  Simultaneously, solvents in the substrate are removed upon solidification, forming micropores similar to extraction.
  Used in coating films such as ion exchange membranes, breathable waterproof films, and filtration membranes.

• Stretching by immersion in liquid

  Stretching can also be achieved in liquid.
  Used in dyeing and stretching of PVA and swelling films.

• Tank fabrication: ICHIKIN’s proprietary technology

  We offer suitable proposals regarding liquid type, tank material, cleaning methods, etc.
  　Tank material: SUS304, SUS316L, PVC, FRP, etc.
  　Liquid type: water, alkalis, sulfuric acid, DMF, MC

Equipment that solidifies resin applied to a substrate in liquid.
In designing equipment, we accommodate various requests such as immersion distance, angle, and dwell time in the liquid.
