  • 1. TARPAULINS: TYPES AND INDUSTRIAL APPLICATIONS Prof. R.B . CHAVAN Former Professor, IIT Delhi Consultant MGIRI, Wardha
  • 2. Subject Content
    • DEFINITION
    • FIBRES USED
    • INDUSTRIAL TARPAULINS
    • FINISHING TREATMENTS
    • TEST EQUIPMENTS
    • APPLICATIONS
  • 3. DEFINITION COMBINATION OF WORDS TAR: TARRED CANVAS PALLING: FABRIC USED TO COVER OBJECTS ON SHIP ALSO CALLED TARP
  • 4. FEATURES THICK CANVAS FABRIC SHEET OF COTTON, COTTON/PET, SYNTHETIC FIBRE FABRIC PET, NYLON, PVC, PE, PP TARPS OFTEN HAVE REINFORCED EYELETS AT THE CORNERS AND ALONG THE SIDES TO FORM ATTACHMENT POINTS FOR ROPE , A LLOWING THEM TO BE TIED DOWN OR SUSPENDED.
  • 5. WATER RESISTANT, FIRE PROOF, ROT RESISTANT UV PROTECTION A) DESIRABLE PROPERTIES ACHIEVED BY SUITABLE COATING: PVC, OTHER HYDROPHOBIC RESINS LIKE PE, PP ETC. ON SYNTHITIC FIBRE FABRICS B) FINISH APPLICATION USUALLY PAD-DRY-CURE TECHNIQUE MAIN APPLICATION FOR COTTON AND COTTON/PET BLENDED TARPAULINS.
  • 6. CLASSIFICATION OF TECHNICAL TEXTILE the range of technical textiles is very large. In the present article it is proposed to discuss a few aspects of the technical textiles or the industrial fabrics falling in the category of tarpaulins.
  • 7. APPLICATIONS AREAS under lays for fertilizers, sugar, tea, coffee and other products. low cost huts, storage bins, mulching, fumigation covers/tents, green houses, mushroom cultivation and other areas. Lining of canals, watercourses, in order to stop seepage losses Agriculture Food grain covers Irrigation APPLICATIONS Industries / Sectors
  • 8. Silkworm trays, lining of industrial tanks, , machinery wrapping, heavy duty sacks Misc. Water proofing/damp proofing of all types of roofs, flooring and under ground structures and construction site dwellings/materials storage tents. Civil Construction Work: Lining of fish ponds/reservoirs Fisheries APPLICATIONS Industries / Sectors
  • 9. Underlay for carpets, table covers, scooter covers, etc. Household: Covers for football Underlay for runway, tents, ammunition dumps, bunker -lining, tank and gun grounds, cricket pitches, tennis courts, tracks pools. Sports: Defence
  • 10. TENSILE STRENGTH TESTER IMPACT TESTER MFI TESTER LEAK DETECTION TESTER QA THROUGH TESTING

  • 12. GLOSS METER HAZE METER COEFFICIENT OF FRICTION TESTER PIN HOLE DETECTOR
  • 13. Cotton Cotton/PET blends Polyester Nylon HDPE/LDPE PP PVC Fibres used
  • 14. FINISHING TREATMENTS
    • DESIRABLE PROPERTIES
    • WATER RESISTANCE
    • FIRE RESISTANCE
    • MICROBIAL RESISTANCE
    • UV PROTECTION
    • FINISHING METHODS:
    • BREATHABLE
    • TOPICAL FINISH: COTTON, COTTON/PET
    • NON-BREATHABLE
    • COATING: NYLON, PET
    • LAMINATION: PE, PP
  • 15. COTTON AND COTTON/PET TARPAULINS SPECIFICATIONS COTTON Warp 88-175 Weft 60-110 Tear strength (N) Warp 980-2190 Weft 590-1860 Breaking strain (N/50mm) Oz/sq yd 7.4-15 gm/sq m 251-610 Weight Plain Weave Cotton 100% Composition

  • 19. FLAME RETARDANT FINISH 1. HALOGENATED BROMINATED FLAME RETARDANTS CHLORINATED FLAME RETARDANTS 2. ORGANO PHOSPHOROUS PHOSPHATE ESTER SUCH AS TRI PHENYL PHOSPHATE 3. NITROGEN-CONTAINING FLAME RETARDANTS 4. INORGANIC FLAME RETARDANTS .
  • 20. ANTIMICROBIAL FINISH
    • COMMERCIAL FINISHES
    • ROSSARI.S FABSHIELD
    • CIBA SPECIALITY CHEMICALS TINOSAN AM
    • CLARIANT SANITZE AG
  • 21. UV PROTECTION DERIVATIVES OF O- HYDROXYL BENZOPHENONES, O– HYDROXYPHENYLTRIAZES, O –HYDROXY PHENYL HYDRAZINES.
  • 22. PVC COATING OVER A BASE CLOTH OF NYLON OR POLYESTER. ROT-PROOF AND WATERPROOF, LESS SUSCEPTIBLE TO DAMAGE FROM ULTRA-VIOLET RAYS, I.E. SUNLIGHT, WEATHER RESISTANCE LIGHTWEIGHT THEY IDEAL FOR COVERING TIMBER STOCK AND BUILDING MATERIALS, THOUGH THEY ARE PRIMARILY USED FOR COVERING GENERAL PURPOSE GOODS IN ROAD TRANSPORT. PVC TARPAULINS

  • 24. SPECIFICATIONS
  • 25. POLY TARPS PE COATING ON NYLON OR PET FABRIC PE FILM LAMINATION (BOTH SIDES) ON PE FABRIC TWO TYPES READYMADE OF DESIRED SIZE POLYTARP ROLLS BOTH TYPES REINFORCED WITH EYELETS
  • 26. CHARACTERISTICS
    • Strong and tear resistant.
    • Flexible - poly tarp is basically a sheet of coated fabric.
    • Water resistant or waterproof.
    • Reinforced with eyelets as attachmnent points for rope
    • U V protection
    • Arctic flexibility - most poly tarps function well at freezing
    • temperatures.
    • Mildew resistant
    POLY TARPS ARE USUALLY THE LEAST EXPENSIVE TYPE OF TARPS AND MOST WIDELY USED.
  • 27. LDPE OR HDPE FILMS ARE USED FOR BOTH SIDE LAMINATION OF PE FABRICS TO PRODUCE POLY TARP. THE THICKNESS OF THE LAMINATION FILM VARIES FROM 40 MICRONS TO 1500 MICRONS WIDTH FROM 1 M TO 13.5 M. LAMINATION FILM FOR POLY TARP
  • 28. LAMINATION FILM CHARACTERISTICS
    • Good tensile and tear strength
    • better optical clarity.
    • Dimensionally stable under varied climatic/temperature conditions.
    • Tolerate temperatures variations ranging from -70°F to 165°F.
    • Offers excellent chemical resistance to Acids, Alkalies, Fungi/Bacteria & Grease; do not corrode metals, is odourless and tasteless.
  • 29. CONTAINS NO PLASTICISER AND DO NOT BECOME BRITTLE WITH TIME AND USE. RESISTANT TO ULTRA-VIOLET RAYS LIGHT WEIGHT EASY OF HANDLING & TRANSPORTATION. WATER PROOF, DUE TO WHICH IT IS IMPERMEABLE TO LIQUIDS AND IS UNAFFECTED BY HUMIDITY.
