LOGIC OF PLUVIA BLEACHING SYSTEM

  • 1. IMPREGNATION SYSTEM

    System has hydraulic pistons to create required nipping forces. Hydraulic system offers the possibility of reaching constant tightening forces against changing rubber structures. For homogenous diffusion of chemicals, continuous circulation is applied for the effluent.

  • 2. STEAMING SYSTEM

    The path of the fabric inside the cabin is extended and thus the steam contact time is increased. In steaming chambers, steam is directed to the surface of the fabric with a special angle. In the meantime, saturated humidity is maintained by evapurating boiling the water inside the chambers. The dwell time is around 4-6 minutes for each chamber. During steaming process, fabric is transferred between j-boxes, so that the fabric contact points with the metal surfaces changes. With all these design features, local drying and contact spots, right-left and head and tail differences do not occur during steaming process.

  • 3. LAYOUT ADVANTAGE

    Conventional continuous bleaching machines occupy space of 150-200 m2. Our Pluvia Pura Bleaching machine occupies only 75 m2 via its modular and compact design.

SYSTEM IN BLEACHING MACHINE

  • 1. DEMINERALIZATION

    Iron ions, which can come from the fabric, water and chemicals, are eliminated in this process.

  • 2. WASHING BEFORE IMPREGNATION

    Prewash process is carried out after demineralization just before the chemical application in the impregnation system. Drum washing chambers are used for woven fabric, while j-box washing chambers are used for knitted.

  • 3. IMPREGNATION SYSTEM

    The pre-washed fabric is nipped with hydraulic nipping cylinders which ensures highest pick-up values. Then, the fabric enters in the chemical effluent tank. The chemical amount on the fabric is precisely adjusted with hydraulic cylinders. System has hydraulic pistons to create required nipping forces. Hydraulic system offers the possibility of reaching constant tightening forces against changing rubber structures. For homogenous diffusion of automatically dosed chemicals, continuous circulation is applied for the effluent.

  • 4. PAD-STAEM CHAMBERS

    The path of the fabric inside the cabin is extended and thus the steam contact time is increased. In steaming chambers, steam is directed to the surface of the fabric with a special angle. In the meantime, saturated humidity is maintained by evaporating the water inside the chambers. The total dwell time is around 10-15 minutes. During steaming process, fabric is transferred between j-boxes, so that the fabric contact points with the metal surfaces changes. With these design features, local drying and contact spots, right/left and head and tail differences do not occur during steaming process.

  • 5. WASHING AND NEUTRALIZATION CHAMBERS

    After steaming, fabric is washed off and automatically neutralized to the desired pH value. Drum washing chambers are used for woven fabric, while j-box washing chambers are used for knitted.
