TECHNICAL YARNS
Friction spun yarns have a core and sheath construction; the core adding strength, whilst the sheath adds bulk to the yarn to increase insulative properties. This method of yarn manufacture also enables the inclusion of wires, to provide extra mechanical strength.
This enables us to offer a bespoke engineered yarn to match the end user requirement.
These yarns are also used for the in-house weaving of our own High Performance Textile fabric.
PERFORMANCE PROPERTIES
Heat & flame resistance
Cut resistance
Abrasion resistance
Chemicals resistance
Tensile strength
Yarns can be enhanced when blended or combined with other fibres or filaments.
TYPICAL APPLICATION AREAS
• Industrial seals and packings
• Gas mantle ties & wicks
• Knitting and weaving of heat and cut-protective clothing
• Braiding
FIBRES USED
Para-aramid (incl. Kevlar®), Meta-aramid (incl. Nomex®), Preoxidised acrylic, Polyacrylate, Polyphenylene sulphide (PPS), FR viscose and other specialist fibres on request. These fibres can be used 100% in the sheath or blended to combine specific properties.
YARN TREATMENTS
Our in-house yarn treatment plant can be used to apply an array of chemical finishes to enhance the yarn properties as required.
MANUFACTURING CAPABILITY
TBA Protective Technologies uses DREF 2, DREF 2000 and DREF 3 spinning machines to manufacture yarns ranging in count from 60 tex (15Nm) to 1000 tex (1Nm). Yarn can be plied up to 6-ply and wound onto packages suitable for the customer’s end use (max. 3kg weight). It is possible to insert 2 cores into the DREF spun yarns, enabling the incorporation of metallic wires if desired. Yarns are usually made-to-order to customer-specific requirements. Glass fibre yarns (including textured) are also available from our Thermal Protection Division.
NONWOVEN FABRICS
TBA uses needle-punch technology to produce nonwovens from a wide variety of technical fibres. A scrim may be incorporated into the felt to provide increased strength and dimensional stability.
FIBRES USED
Para-aramid (incl. Kevlar®), Meta-aramid (incl. Nomex®), Preoxidised Acrylic, FR Rayon, Polyacrylate, Polyamide-imide and others available on request.
PERFORMANCE PROPERTIES

Cut resistance
Abrasion resistance

Yarns can be enhanced when blended or combined with other fibres or filaments.
TYPICAL APPLICATION AREAS
• Heat protective clothing – INY & INYA
• Glove liners – ANU/INU
• Molten metal splash protection – INY/INYA
• Cut-protection clothing – ANU/KNU
SPECIAL TREATMENTS & COMPOSITES
Aluminised – the adherence of an aluminised film imparts radiant heat reflectivity to the nonwoven fabric
Composites – TBA utilises quilting technology, heat lamination and needling to provide multi-layer composites where required.

WOVEN FABRICS
TBA produces a range of woven fabrics from ring spun, friction spun (DREF) and continuous filament yarns, for a variety of high temperature and mechanical risk applications.
PROPERTIES
Our KC range of fabrics uses a glass cored yarn with an aramid sheath for temperatures up to 450°c. OKC fabrics use a blend of high performance fibres that produce a fabric with excellent resistance to heat and metal shedding.
PERFORMANCE PROPERTIES
Heat & flame resistance
Cut resistance
Abrasion resistance
Chemicals resistance
Tensile strength
Yarns can be enhanced when blended or combined with other fibres or filaments.
APPLICATION AREAS
• Industrial sealing
• Cut resistant clothing
• Thermal insulation
• Protective clothing
• Electrolytic diaphragms
WEAR RESISTANCE
Many of our fabrics contain para-aramid to increase their cut and wear-resistance properties. For additional resilience, a wire core can be inserted into the yarn for cut-resistant gloves and garments.
ARAMID WEBBING
Woven webbing tape provides exceptional strength and performance properties. It is manufactured utilising glass/para-aramid yarn produced in-house, either as a continuous filament or spun.
We can produce as narrow as 20mm and up to 100mm as standard, with wider tapes available if required. In addition to very high tensile strength, the webbing additionally provides thermal, cut and abrasion resistance. Within our webbing production we also use proprietary materials including Kevlar® and Nomex®
Applications for webbing can be very varied and the product is typically developed and manufactured to match a particular customer requirement, driven by the final use. TBA webbing has been used in applications as diverse as chinstraps on military combat helmets through to use in fire-eating sticks, with an array of industrial uses in between.

ALUMINISED FABRICS FOR PROTECTIVE CLOTHING
TBA Protective Technologies manufactures aluminised fabrics which are widely used to fabricate items of protective clothing such as gloves, mitts, aprons, jackets, trousers and fire proximity suits. These are used within industry to protect workers from heat and welding splash. A variety of base fabrics can be offered depending on the application involved.
All batches of aluminised fabric for protective clothing undergo a wet-flex test prior to release, to assure the adhesion between the fabric and film.
We only use polyester film that is aluminised on both sides, so that some degree of radiant heat protection is still offered if some of the outer layer of aluminium is worn away, thus extending the life of the garment.
PERFORMANCE PROPERTIES
Heat & flame resistance
Cut resistance
Abrasion resistance
Chemicals resistance
Tensile strength
Yarns can be enhanced when blended or combined with other fibres or filaments.
