Workwear Fabrics

It draws together technical and scientific expertise from around the world to produce an important source of present knowledge on fire-resistant textiles and their use for protection in hostile surroundings. Part one provides an overview of fire resistant textiles. Chapters discuss burning and combustion mechanics of textile fibers, chemical modification of natural and artificial fibers to improve flame retardancy, multi-component flame-resistant coating techniques for fabrics, care and maintenance of fire-resistant fabrics, together with the security, health and environmental aspects of fire retardants. Part four includes case studies of important applications of flame-resistant fabrics.  The Handbook of fire-resistant cloths is a priceless resource for a wide range of professionals in the textiles and apparel industries.

Fire Resistance Garments 

such as textile and garment makers, engineers, researchers, designers, developers, and buyers. gives a comprehensive review of the considerable advances that have happened in the field of fire-resistant textiles in recent years  Discusses combustion and burning mechanisms of textile fibers and chemical modification of natural and synthetic fibers to increase flame retardancy  Covers different kinds of fire-resistant fibers and materials, including flame-retardant cotton, wool, ceramic fibers, and blends, composites and nonwovens. Fire Retardant Textiles Although all Textiles will burn, some are more resistant to fire than others.  Those which are more flammable can have their fire resistance drastically improved by therapy with flame retardant compounds called flame Retardant Textiles.  


Introduction of protective Clothing

History Asbestos was a miracle material.  An abundant stone, it divides fibers which mix readily with plaster, fabrics, tiles, and construction materials, which makes them all extraordinarily fire-resistant.  But these fibers do not stop there.  When tiles break or insulation crumbles, boilers shatter or dust collects, those asbestos fibers crawl their way into people’s lungs, where they cause cancer and other ailments. Value of Fire Retardant Textiles  Recent studies have shown that at 24 percent of fire accidents, the first item to catch fire would be textiles percent casualties were due to burns percent because of smoke/gas percent due to combined effects of burns, gas and smoke  11% due to other causes  These emphasize the use of textiles in restricting the spread of fire and casualties because of it.


Non Flammable Textiles

fabric flammability is a significant issue, especially for stage drapery which will be utilized in a public space like a school, theatre or special event venue.  The use of reduced flammability materials, testing of both materials and complete products, regulations, and legislation have been applied to the issue.  Contd. Factors Influencing The Flame Retardancy  The thermal or draining behavior of textile fibers  The influence of fabric structure and garment shape on the burning behavior  Choice of non-toxic, smoke-free flame-retardant additives or finishes  Design of the protective garment, based on its use, with relaxation properties  The high level of the ignition supply  The oxygen source. Flame retardancy is commonly measured by the LOI, the quantity of oxygen required from the air to support combustion.  


FR CLothing Thermal Vulnerability Traps 

Fibers/fabrics with an LOI >25 are said to be flame retardant, meaning that there must be at least 25% oxygen present for your own cloth to burn off.  The higher the LOI the longer flame retardant the fabric is. Functions of fire retardant textiles Keep a barrier to isolate the wearer against the thermal vulnerability Traps air between the wearer and the barrier to Give insulation from the exposure Reduce injury Give escape time Doesn’t burn, melt or drip Requirements in FR Merchandise:  Fire and warmth protection.  (Additionally, if needed, other Protection attributes: High visibility, antacids, antistatic…)  Comfort, aesthetics, durability.  (Breathability, strength, abrasion, steady colorfastness, easy-care, weather resistance.)   Price.  (The cost has to be reasonable and based on the different risk circumstances. The best solutions at the best cost )

FR Clothing chemical therapy 

The flame retardant cloth can be achieved by some methods  FOR by chemical therapy  FR by heat resistant fibers  FR by appropriate Structural Engineering  FR by chemical therapy what’s FR chemical therapy?  Flame retardant is identified as a chemical used in plastic and cloth material to elevate the ignition point of the material, thus rendering it resistant to flame.  So for enhancing the FR properties of clothes with assistance of substance is chemically treated FR fabric. Classification of FR chemical treatment on the Grounds of this durability of the fire retardant finish-  Non-durable treatment  Semi-durable therapy  Durable treatment On the basis of the functional category –  Nitrogen-containing flame retardants  Halogen containing fire retardants,

Fire retardants Nitrogen Containing

Phosphorus-based fire retardants  Inorganic compounds based fire retardants Nitrogen Containing FR Mechanism  Nitrogen gas is discharged into the air  Inert gas lowers the concentration of flammable vapors  Melamine transforms into cross-linked structures that promote char formation utilizes: Foams, Nylons, and Polymers. Halogenated FRs  that the Act in the Vapor stage  Reduce the heat produced by flames, thus inhibiting the formation of flammable gases  Behave based on some”Free Radical Trap” theory which is portrayed as follows. 

Decomposition Reactions 

Phosphorus Containing FRs  Acts in solid-phase  Additive to the substance it’s protecting  Reacts to form phosphoric acid  Acid coats to make”char”  Char slows down the pyrolysis step of the combustion cycle. Inorganic FRs  Undergo decomposition reactions  Release of water or naturally-occurring pollutants which dilute the gases consuming flames  Adsorption of heat energy cools the flame  Promote production of a non-flammable, Flame retardant textiles resistant layer on the substance’s surface  Programs: PVC, Wires, and Propylene
