Title: What is Technical textile??


1
What is Technical textile??
  • Principally all those fabrics which exhibit
    Performance or some desired characteristics

2
Performance??
  • How to check Performance?

3
What can be measured, can be Managed
  • Peter Drucker

4
Do we need Protection??
  • Against what???

5
Some hard facts
  • Worldwide more than 2 million people die annually
    as a result of accident at work or vocation
    diseases.

6
Protection against our working Environment
  • Oil Rigs Refineries
  • Steel Aluminum Furnace
  • Fire Rescue Department
  • Airlines and Crew and Ground Staff
  • Shipping lines crew
  • Racing Drivers and Support Crew
  • Power Generation and Distribution
  • Mining
  • Chemical Industry
  • Arms and Ammunition Industry
  • Constructions
  • Defense Forces

7
Protection Against Hazards
  • Protection against Fire
  • Protection against Heat
  • Protection against Electric Arc
  • Protection against Molten Steel Aluminum
  • Protection against Cuts
  • Protection against Fall
  • Protection against Sudden Impact
  • Protection against static charge

8
Electrical Power Distribution
  • Need Protection against Electric Arc.
  • Need Protection against Static charge.
  • Need Protection against heat.

9
What is Electric Arc
  • Passage of Substantial electric current thru
    Ionized Air.
  • Typically lasts less than a second.
  • Extremely high radiant energy.
  • Can Ignite or melt Normal clothing.

10
Arc Flash Events
  • Arc Flash happens when typically when Electrical
    equipment is being disconnected, tested,
    inspected or serviced. It can be caused by
  • Accidental contact with live parts.
  • Insulation failure
  • Close proximity of conductive subject.

11
Power sector Electric arc Protection
  • Electric Companies in USA use ASTM 1959/F for
    measuring the ATPV arc rating.
  • Based on these ratings, fabrics are classified as
    HRC class 1, HRC class 2 or HRC class 3.
  • Electric Companies In Europe follow standards of
    Electric Arc EN 61482-1-22007-03. Specified
    current value is passed thru electrodes. The
    sample kept at 1 ft distance. Purpose is to save
    the wearer from 2nd Degree Burns.
  • EN 1149-5 is widely used as standard for
    measurement against static charge generation.

12
Oil Rigs and Refineries
  • Need Protection against Flash Fire.
  • Flash fire is sudden burst of energy for less
    than 3 seconds.
  • Need Protection against heat.
  • Need Protection against Flamability.

13
Possible hazards in Oil sector
  • Flash Fire is Sudden Intense Fire caused by
    Ignition of Mixture of air and Flammable solid or
    gas
  • It has high Temperature and short duration.
  • High visibility needed for easy rescue.
  • Exposure to heat and flame in close proximity.

14
Standards for Oil Industry
  • ISO 174932000 - testing at 180C the protection
    against heat
  • Expected Result Should not Ignite, Melt or Burn
  • ISO 150252000A Put the substrate to edge
    ignition for 10 seconds..check Flame Spread.
  • Expected Result No Flaming, holing, melting and
    Afterglow.
  • Ralph test less than 50 2nd Degree burn on
    flash Fire manikin test.
  • Standards used are ISO 11612, RALPH TEST and
    ASTM 6413.
  • EN 1149-3 for testing the fabrics antistatic
    charge dissipation properties in the Low Humidity
    areas.

15
Steel Aluminum Industry
16
Steel and Aluminum Industry
  • Need Protection against Molten metal( Aluminum
    or steel) splash.
  • These splash can cause severe burns and can cause
    death.
  • Need Proetction rfom High temperature.
  • Need Protection from Flash Fires.

17
Standards for Steel/Aluminum Industry
  • EN 373 involves the checking number of molten
    drops on the fabric to make hole.
  • Different levels of D1, D2,D3 defined for
    Aluminum.
  • Levels E-1, E-2, E-3 defined for Steel.
  • Different Products have to be used based on the
    applicable industry.
  • EN 13034 involves checking the garment against
    Chemical splash.
  • EN 11612 is widely accepted standard for
    protection against heat and Flamability.

18
Construction
  • Protection against Dust and filth
  • Protection against Sharp objects
  • Protection against low Visibility.
  • Protection against Welding ,gas cutting gas
    cutting debris.

19
Standards for construction industry
  • EN 470-1 (new standard ISO 11611) for protection
    against molten metal spatter during welding.
  • The standards consist of testing against Limited
    Flame spread (EN 532), spatters of molten metal
    (EN 348)
  • Protection against Rubs, tears and cuts.

20
Defense Forces
  • The success of military camouflage led to the
    development of surveillance technology. Based on
    Near-IR technology, modern equipment allows
    identification of the personnel from surroundings
    in the dark.
  • This means military camouflage also requires
    reflectance values in the Near- IR range that
    matched the expected surrounding topography.
  • For military personnel, it is necessary to wear
    the appropriate clothing that attempts to
    minimize the contrast between objects and their
    environment over the NIR region in addition to
    the visible region.

Current Indian Scenario
  • Safety in Industry is not given its Due
    Importance.
  • Workers working at the Blast Furnace wear cotton
    cloths at best to avoid flame.
  • Construction Workers hardly have any protective
    belt or gear.
  • Indian defense forces are happy with the basic
    camouflage.
  • Safety standards are either derived from USA or
    Europe, but they are hardly followed.
  • Accidents are hidden under the carpet to avoid
    claims.
  • PPE are kept for showcase.

27
Summarise the discussion
  • Performance should be measured.
  • Measurement has to be against needs.
  • Needs of the Industry should be Expressed in
    terms of Values.
  • Test methods need to be devised considering the
    requirements of the Industry.
  • Required standards need to be specified against
    these tests.
  • Tests and standards have to be relevant to the
    Industry.
  • The strong law enforcement for the standards is
    the key.
  • BIS has to play an Important role by conducting
    frequent meetings of Standards committee
    including Industry nominees.
