What is Technical textile??

Principally all those fabrics which exhibit Performance or some desired characteristics

HOW TO CHECK PERFORMANCE?

Performance??

PETER DRUCKER

“What can be measured, can be Managed”

AGAINST WHAT???

Do we need Protection??

Some hard facts

Worldwide more than 2 million people die annually as a result of accident at work or vocation diseases.

Electrical Power & Distribution

Need Protection against Electric Arc.

Need Protection against Static charge.

Need Protection against heat.

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.

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 failureClose proximity of

conductive subject.

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 61482-1-2:2007-03. 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.

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.

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.

Standards for Oil Industry

ISO 17493:2000 : - testing at 180C the protection against heat

Expected Result – Should not Ignite, Melt or BurnISO 15025:2000A – 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.

Steel & Aluminum Industry

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.

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.

Construction

• Protection against Dust and filth

• Protection against Sharp objects

• Protection against low Visibility.

• Protection against Welding ,gas cutting gas cutting debris.

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.

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.

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.
