    • EXCELLENT HAND, DRAPE AND RESILIENCE
    • WRINKLE RESISTANCE
    • QUALITIES FROM SILK LIKE TO COTTON LIKE
  • 4.

  • 5. APPLICATIONS
    • FIBRES
    • DESIRABLE FIBRE PROPERTIES
    • PLA IS FIRST MELT PROCESSABLE NATURAL BASED FIBRE
    • PROVIDES A BRIDGE BETWEEN NATURAL AND SYNTHETIC FIBRES
  • 6.
    • PLA IS READILY CONVERTED INTO VARIETY OF FIBRE FORMS USING CONVENTIONAL MELT SPINNING PROCESSES
    • FIBRES FROM PLA DEMONSTRATE EXCELLENT RESILIENCY, OUTSTANDING CRIMP RETENTION AND IMPROVED WICKING COMPARED TO NATURAL FIBRES
    • FABRICS PRODUCED FROM PLA ARE KNOWN FOR SILKY FEEL, DRAPE, DURABILITY AND MOISTURE MANAGEMENT PROPERTIES
  • 7. ADVANTAGES OF PLA OVER PET
    • LOW FLAMMABILITY AND SMOKE GENERATION
    • EXCELLENT UV STABILITY
    • HIGH LUSTURE
    • LOWER DENSITY
  • 8. FIBRE APPLICATIONS
    • PLA CAN BE USED FOR WIDE RANGE OF WOVEN, KNITTED AND NON-WOVEN APPLICATIONS
    • CLOTHING (FASHION WEAR, UNDER WEAR, SPORTS WEAR, UNIFORM ETC)
    • WOOL, SILK AND COTTON BLENDS
    • WIPES
    • CARPERT TILES
  • 9.
    • DIAPERS
    • FEMININE HYGEIN
    • UPHOSTERY, INTERIOR AND OUT DOOR FURNISHING
    • FILTRATION
    • GEO-TEXTILE FOR SOIL EROSION CONTROL
  • 10. PACKAGING
    • DESIRABLE PROPERTIES
    • PLA IS ALTERNATIVE TO TRADITIONAL, DISPOSABLE PACKAGING
    • VERSATILITY AND PROCESSABILITY
    • CAN BE EXTRUDED, ORIENTED, THERMOFORMED WITH EXISTING EQUIPMENTS
    • OUTSTANDING CLARITY AND GLOSS, EQUIVALENT TO ORIENTED PP AND PET
  • 11.
    • UNIQUE BARRIER PROERTIES
    • LOW TEMPERATURE HEAT SEAL
    • CRYSTALLINITY CAN BE MODIFIED TO SUIT PRODUCT REQUIREMENTS
    • TENSILE STRENGTH AND MODULUS EQUIVALENT TO PET
  • 12.
    • EXCELLENT RESISTANCE TO WIDE RANGE OF GREASES, FATS AND OILS
    • EXCELLENT PRINTABILITY
    • BIODEGRADABILITY : PLA BIODGRADES COMPLETELY IN COMPOST CONDITIONS
    • NATURAL ORIGIN
  • 13. APPLICATIONS
    • PROPERTIES MOST SUITABLE FOR FILM AND TERMOFORMIMG
    • FILMS
    • HIGH CLARITY FILMS AS AN ALTERNATIVE TO CELLOPHANE FOR USES LIKE CONFECTIONARY WRAP, FLOWER WRAPPING TOLETORIES AND PRESTIGE GIFTS
    • BAGS FOR COMPOST AND GARDEN REFUSE, AGRICULTURAL MULCH FILM TO REPLACE PAPER
  • 14.
    • WIDE VARIETY OF MULTI-LAYER FILMS FOR PACKAGING USES SUCH AS FLAVOURED CEREALS, COFFEE PACKS AND PET FOODS
    • WINDOW FILMS FOR ENVELOPS
    • LAMINATION FILMS
    • RIGID THERMOFORMED CONTAINERS
  • 15. END USE PRODUCTS
    • PACKAGING OF DAIRY PRODUCTS
    • CANDY WRAPS
    • FAST FOOD CUPS
    • FRESH FOOD CONTAINERS
    • ICE CREAM HOLDERS
  • 16.
    • FLAVOURED CEREAL PACKAGING, COFFEE PACKS
    • SNACK FOOD, MILK AND FRESH YOGURT
    • COMPOST BAGS
    • ALL THE PRODUCTS ARE COMPLETELY BIODEGRADABLE IN COMMERCIAL COMPOST CONDITIONS
  • 17. EMERGING APPLICATIONS
    • BLOW MOLDING : IJECTION STRETCHED BLOW MOLDED BOTTLES
    • EMULSIONS : WATER BASED EMULSIONS FOR PAPER AND BOARD COATING, PAINTS, BINDERS FOR NON-WOVENS, ADHESIVES
    • LACTIC ACID DERIVATIVES AS
    • CHEMICAL INTERMEDIATES FOR HOT MELT ADHESIVE, SURFACTANT, ACRYLIC ESTER
  • 18.
    • REDUCE FOSSIL FUEL USE
    • CONVENTIONAL HYDROCARBON POLYMERS UTILIZE OIL AS THEIR FEEDSTOCK SOURCE
    • MONOMER FOR PLA IS DERIVED FROM ANNUALLY RENEWABLE RESOURCE
    • ENERGY FROM SUN AND CARBON DIOXIDE FROM AIR ARE HARNESSED IN AGICULTURE CROPS
    ENVIRONMENTAL BENEFITS
  • 19.
    • ONE THIRD OF THE ENERGY REQUIREMENT OF PLA IS DERIVED FROM THESE RENEWABLE RESOURCES
    • PLA UTILIZE 20 - 40% LESS FOSSIL FUEL THAN OTHER POLYMERS DERIVED DIRECTLY FROM HYDROCARBONS
    • FOSSIL FUEL PROVIDES ENERGY TO RUN PLA PRODUCTION CHAIN e.g. MILLING , FERMENTATION , POLYMERIZATION AND TRANSPORTATION
  • 20. CARBON CYCLE
    • CARBON DIOXIDE IS MAJOR CONTRIBUTOR TO GLOBAL WARMING
    • BECAUSE CARBON DIOXIDE IS REMOVED FROM AIR WHEN CORN IS GROWN , PLA HAS THE POTENTIAL TO RESULT IN REDUCED IMPACT ON GLOBAL WARMING COMPARED TO MOST HYDROCARBON BASED POLYMERS
  • 21. BIODEGRADABILITY OF PLA
    • PLA FIBRE WHEN SUBJECTED TO GROUND BURRYING, MARINE WATER AND ACTIVATED MUD TESTS
    • DECREASE IN TENACITY
    • INCREASE IN WEIGHT LOSS
    • IN GROUNDAND MARINE WATER TESTS THE FIBRE IS PRACTICALLY DECOMPOSED WITHIN TWO YEARS
    • ACTIVATED MUD TEST, DECOMPOSITION IN 2-3 MONTHS
  • 22.
    • COMPARISON WITH TRADITIONAL FIBRES
    • CONVENTIONAL PET RETAINS THE SHAPE AND PROPERTIES UNDER ALL BIODEGRADABILITY TESTS
    • CELLULOSIC FIBRES (COTTON AND VISCOSE) ARE DECOMPOSED MORE RAPIDLY THAN PLA IN ACTIVATED MUD
  • 23. WASTE DISPOSAL
    • PLA PRODUCTS CAN BE DISPOSED OFF BY TRADITIONAL WASTE MANAGEMENT METHODS SUCH AS
    • LANDFILL
    • LANDFILL TESTS HAVE NOT BEEN CARRIED OUT WITH PLA POLYMERS
    • ITS WATER INDUCED (HYDROLYSIS) DEGRADATION MECHANISM IS WELL UNDERSTOOD
  • 24.
    • IN PRESENCE OF MOISTURE PLA POLYMERS DEGRADE INTO LACTIC ACID (MONOMER) EVEN IF MICROBES ARE NOT PRESENT
    • PLA POLYMER DEGRADATION RATE IS DEPENDENT ON TEMPERATURE AND HUMIDITY
    • AT TYPICAL LANDFILL TEMPERTATURES, THE EXPECTED DEGRADATION TIME FRAME WOULD BE BETWEEN 2 AND 10 YEARS
    • FOOD WASTE AND PAPER MAY PERSIST FOR LONGER PERIOD IN LANDFILL BECAUSE THEY REQUIRE BACTERIA TO DEGRADE
  • 25. INCINERATION
    • PLA POLYMERS INCINERATE CLEANLY WITH REDUCED ENERGY YIELD COMPARED TO TRADITIONAL POLYMERS
    • PLA POLYMERS BURN MUCH LIKE PAPER AND CELLULOSE
    • BURNS WITH WHITE FLAME
    • IT CONTAINS NO AROMATIC GROUPS OR CHLORINE
    • PRODUCES FEW BY PRODUCTS AND 0.01% ASH.
  • 26.
    • MUNICIPAL COMPOSTING
    • PLA POLYMERS ARE FULLY COMPOSTABLE IN MUNICIPAL COMPOSTING FACILILITIES
    • PLA COMPOST CAN BE RECYCLED FOR CORN CULTIVATION
    • PLA POLYMERS COMPOST BY TWO STEP PROCESS
  • 27.
    • FIRST CHEMICAL HYDROLYSIS (REACTION WITH WATER) REDUCES THE MOLECULAR WEIGHT OF POLYMER
    • THEN MICRO ORGANISMS DEGRADE THE FRAGMENTS AND LACTIC ACID INTO CARBON DIOXIDE AND WATER
    • HEAT AND WATER STIMULATE DEGRADATION OF PLA POLYMERS
  • 28. CONCLUSIONS
    • THE NEW ECO FRIENDLY SYNTHETIC FIBRE BASED ON CORN AS RENEWABLE SOURCE WOULD FIND WIDE ACCEPTABILITY IN THE AREA OF
    • CONVENTIONAL TEXTILES
    • TECHNICAL TEXTILES
    • NON TEXTILE APPLICATIONS
  • 29.
    • IT WOULD MEET TH E REQUIREMENTS TO COPE UP WITH THE DEPLETING FOSSIL FUEL RESOURCES AND ENVIRONMENT PROTECTION
    • IT IS ENVISAGED THAT IN THE NEAR FUTURE MANY COMPANIES WOULD ENTER INTO PRODUCTION OF ECO FRIEDNLY PLA FIBRES AND OTHER PRODUCTS.
