3. Protective Clothing
Protective clothing definition involves garments, or
textile related products that are worn, that prevents
a person (or product) from coming into contact with,
that protects from, and/or reduces the risk of
exposure to hostile elements or environments.
Protective clothing extends to body armor such
as bullet proof vests, historical armor and
futuristic powered armor along with normal clothing.
But In UK legislation the term PPE does not cover
such items as armor.
5. Heat and Flame Resistant clothing
The turnout gear (Jacket and trouser only)
typically consists of three functional gears:
• Outer shell (OS) - resistance to fire and
prevents water ingress, cut, stab, tear and
abrasion hazards. i.e. Gemini XTL(TENCATE)-
PBI; Nomex (Dupont)
• Moisture Barrier (MB) - prevent water, HT
water vapor, chemicals and other pathogens.
i.e. STEDAIR3000 (Stedfast) -Bi-component
PTFE.
• Thermal Liner (TL) – provides thermal
protection. i.e. Caldura(TENCATE)
6. • Dupont (Nomex) –
Withstand short exposure up to 1000ᵒC.
• Sparco (Hocotex)
• Lighter suit in the world
7. Protection against Extreme Cold Wet weather
Garments that can manage moisture, control heat transfer and protect human from the weather
must work together. Wearing the proper clothing system will ensure the optimal combination of
comfort and protection.
THE BASE LAYER — Worn next to the skin, this layer is made of non-absorbent fibers that “wick”
liquid away from the skin.
THE INSULATING LAYER — Worn over the base layer, this layer keeps warm the body. Synthetic
insulators work better than natural fibers and retain some of their insulating ability even when wet.
THE WEATHER PROTECTION LAYER — This layer protects against the elements while keeping the
insulating layers dry. And it must be breathable to keep moisture from accumulating in the other
layers.
8. Gore-tex
• THREE LAYER GORE-TEX® ACTIVE FABRIC:
GORE-TEX® Active fabric combines a lighter,
thinner GORE-TEX® membrane with fine
denier performance textiles to deliver the
ultimate lightweight three-layer solution. On
the liner side, a proprietary lamination
technology integrates the backing textile
directly into the GORE-TEX® membrane
allowing for extreme breathability and
excellent next-to-skin comfort.
9. Polartec Fleece Jacket
Polartec® fleece (PET) has a lofted fiber structure
that creates thermal air pockets to prevent
convective heat loss and regulate core warmth. This
breakthrough design construction provides the
highest warmth per weight ratio for insulating
materials while remaining highly weather resistant,
durable and soft to the touch.
A soft double-sided face gives fleece the versatility
to integrate with layered systems, whether worn
directly against the skin or on top of other fabrics.
The hydrophobic properties further enhance the
inherent ability to repel water, resist saturation and
dry quickly
10. Pertex fabrics
• Pertex developed new Pertex Shield AP and a lighter
weight version of Pertex Shield+ (Nylon and PTFE), in
response for the growing demand for extremely-
lightweight, weatherproof outerwear.
• Y-shaped filaments inside the yarn, which lock together
to provide a more stable construction.
• 100 DWR has been developed to provide excellent
water shedding through extended wash and wear.
• Pertex fabrics with CS10 technology use yarns with
unique diamond shaped filaments, which lock together
to provide a very stable construction. These tightly
interlocking filaments give the fabric superb abrasion
resistance along with improved water beading
properties.
11. Protective Clothing for Military
• FR-blend underwear next to skin.
• A base layer of a long sleeved top and drawers
composed of Nomex/spandex mesh.
• Mid-weight layer of long sleeved top and bottom
of Nomex/FR polyester fleece.
• Duty service uniform layer with FR options for air
and mounted personnel.
• Lightweight outer layer of FR wind-resistant
nylon/cotton/Lycra® blend.
• Intermediate weather outer layer of fleece
jacket, pants and vest of the nylon/cotton/Lycra
blend.
• For extreme weather, an outer layer of a shell
jacket and pants of FR rayon/para-aramid/nylon
outer shell, PTFE membrane and Nomex knit
jersey backing.
12. Protection against ballistic
• The TenCate Themis™ family of soft body
armor inserts consists of five models that
protect against ballistic, fragmentation,
spike and edged blades.
TenCate Advanced Armor
North America announces a
new line of personal
protection products offering
higher levels of life-saving
capabilities.
• TenCate Pro-Tector® 1000 is
a woven aramid laminate
multi-thread material.
• TenCate Aramid-Shield™
1000 is a uni-directional
aramid ballistic material.
• The TenCate Cratus™ family of hard body
armor plates consists of fourteen models
that protect against the full range of
handgun, edged blade and rifle threats
typically seen in law enforcement and
military operational environments.
13. DuPont™ Kevlar® fiber for military soft body armor
Kevlar® technology in military-grade protection has multiple uses:
• Improved Outer Tactical Vest (iOTV)
• Improved Modular Tactical Vest (iMTV)
• Throat and groin protectors
• Deltoid Auxiliary Protection System (DAPS)
Kevlar® XP™ for Hard Armor Helmet helps provide:
• Minimal back face deformation
• Fewer layers and can reduce stitching requirements
• 20% decrease in helmet weight
14. Helmet (ski racing )
• Giro Sport Design, the leader in the
manufacture of protective headwear, has
announced the Advance MIPS(Multi-
directional Impact Protection System), an
innovative ski racing helmet that uses
TeXtreme to create a lighter, stiffer, and
stronger shell.
• TeXtreme is a unique carbon fibre
material that differs from conventional
carbon fibre materials due to its
proprietary production methods.
15. Protective clothing against chemical
• Chemical-Protective Clothing (CPC) consists of special clothing worn to prevent chemicals from
coming into contact with the body. CPC generally includes eye/face protection, aprons, boots,
gloves, and suits/coveralls.
CPC Selection:
• Chemical resistance
• Physical integrity
• Resistance to temperature extremes
• Ability to be cleaned
• Flexibility
• Size
• Design
16. • Higher protection is offered by
Tyvek(durable spunbonded olefin)
laminated with Saranex 23P® from Dow
Chemical. Saranex multi-layered barrier
film has a low density polyethylene outer
layer bonded to a layer of resin, a
copolymer of vinylidine chloride (Saran)
and an exposed layer of ethylene vinyl
acetate (EVA) which acts as an adhesive
to bond Saranex to the Tyvek. Properly
constructed and sealed garments offer
high degrees of protection over a wide
range of chemicals. DuPont has added to
their line of Tyvek materials to include
several lower cost coatings for specific
applications.
Tychem® SL Offers Protection Against
More than 120 Chemicals
17. Protective clothing against Radiation
• Concern in this area involves protection from
radioactive particulate matter or fall-out protection.
Most garments used are impermeable to
particulates to prevent ingestion and/or skin contact
and absorption into the body tissues. The
penetration and permeation protection is offered by
special co-polymer coatings or laminates with broad
spectrum chemical resistance. The base fabric acts
as carrier and/or a strength member to provides
durability consistent with the use and the coating.
Typical would be polyethylene coated fabrics onto
Tyvek(Dupont) or other non-wovens such as
polyester or olefin.
18. • Poland’s Textile Research Institute (TRI) has developed new
textiles enabled with anti-UV and anti-electromagnetic
capacities. Protective clothing developed with the use of
these textiles will be supplied to law enforcement officers,
healthcare workers, farmers and other professions, but they
will also be used in the manufacturing of curtains and other
products.
• Following research and development activities, the TRI is
currently pursuing projects which aim to introduce its
products to both the domestic and foreign markets, according
to the institute’s management.
19. Protective clothing against Bacterial/Viral
• The PC area of medical textiles, as per definition,
has been fueled by the concerns related to the
virus, hepatitis, Ebola and other life threatening
transmittable diseases. Barrier fabrics, laminated
or coated woven and non-woven fabrics with
sophisticated co-polymer extrusion coatings, are
being developed, along with anti-bacterial
finishes for use by hospital and medical
personnel, emergency responders such as
ambulances, firemen, and police. A good
example of the work being done in this area is
DuPont's Biowear® materials(Tychem qc
coveralls) for protection against bloodborne
pathogens Tychem QC coveralls
20. Nanotechnology in Protective Clothing
• Currently available protective textiles (aramids such as Kevlar) are often heavy, bulky, and
uncomfortable with limited protective performance. These characteristics limit their use;
this is where Nano‐enabled textiles may provide a solution.
Nanotechnologies add value
• Due to their enabling character and the unique properties of materials at Nano scale,
nanotechnologies are particularly suitable for use in technical protective textiles. Their
use in this sector is still at an early stage, with research following two main paths:
1. Upgrading functions and performances of existing PC.
2. Development of products with unprecedented characteristics and performance.
• These development streams gives rise to two main classes of products: functional
protective textiles and smart/intelligent protective textiles. Some of these materials
have reached the market, but it must be stressed that many with the most innovative
features have not been tested at full scale, remaining in the early stages of development.
