NovaStar, LC121, Coating and Laminating Machine, Hot-Melt PUR, Gravure Dot Transfer & Slot-Die Coating (New)

Description

  1. Innovation And Core Technology
    1. Friendly environment.
    2. Uses hot-melt PUR for paste; no solvent, poisonous gas, exploding, or burning risk.
    3. Low energy consumption.
    4. No oven, no exhaust gas; total running power under 30 kW.
    5. Dot coating density: max. 400 dot/sq.cm.
    6. Add-on weight: 5-60 g/sq.m; coating thickness: 30-200 um.
    7. Application of slot-dye nozzle; coating amount: 0.8-100 g/sq.m.
    8. Low running tension control: 0.1-10 kg; low noise, low vibration.
    9. Soft handling.
  2. Typical Applications
    1. Protective clothing – firemen suits, medical garments, surgery gowns.
    2. Sports wear.
    3. Hospital mattress covers.
    4. Automotive and decoration – roll good manufacturing.
    5. Lingerie – bra cup (tri ply laminate).
    6. Textile – brassieres.
  3. Principle Of Reactive Hotmelt
    1. Two-stage process: thermoplastic phase and reactive phase.
    2. Thermoplastic phase: hotmelt becomes liquid during and solid after application; provides initial bonding strength.
    3. Reactive phase: PUR starts cross linking under influence of humidity and temperature; after full reaction, cross linked PUR shows final properties (irreversible).
  4. Advantage Of A Reactive Pur Hotmelt
    1. Washing machine at 40 °C, 60 °C, or 90 °C.
    2. Alkaline resistance.
    3. Dry cleaning (resistance against chlorinated solvents).
    4. Sterilisation at 134 °C during 18 minutes (autoclave).
    5. Heat resistance at temperatures up to 200 °C.
  5. Breathable Membranes
    1. PTFE.
    2. PU.
    3. TPU.
    4. PES.
  6. Membranes And Production (Astm)
    1. Membranes: low under 1500, mid 6000-10000, high over 15000 ASTM.
    2. Production: low under 1000, mid 3000-5000, high over 10000 ASTM.
  7. Hot-Melt Coating / Laminating Machine
    1. Material: soft woven knits net fabric, micro fiber, sports fabric.
    2. Paste: hot-melt (1500-8000 pcs).
    3. Heating: thermo-oil heating.
    4. Drive: AC inverter motor with digitalize and analog speed control.
    5. Power: driving 20 kW, heating 30 kW.
    6. Max. temp: 180 °C.
    7. Running tension: 0.1-10 kg.
    8. Coating: gravure dot transfer coating, slot-die spray coating.
  8. Dot Coating
    1. Even coating, full glue spots, small coverage, resulting in better penetration.
  9. Gravure Transfer And Slot-Die Coating
    1. Gravure transfer coating.
    2. Slot die coating.
  10. Pattern Of Gravure (5-60 G/M2)
    1. Diamond-shaped pattern: TA1, TA2.
    2. Random small dot pattern (close): TM1*, TM2*…
    3. To imitate full coating: TN*, TNA*.
    4. Net pattern: KA.
