Product Features

As an industry, we have been trained to think that you cannot have maximum thermal protective performance (TPP) and also have maximum total heat loss (THL). Introducing a game changer for the fire service, TECGEN71. 

TECGEN71 is an outer shell designed to lessen heat stress by reducing weight and increasing flexibility.

TECGEN71 features rip twill construction that puts the proven strength of 60/40 Kevlar®/Nomex® on the face of the fabric, while creating a super structure of the TECGEN® fiber inside.

TECGEN71 is the most lightweight, thin, and flexible fabric composites with the highest THL ever seen in the fire service… without sacrificing thermal protection or durability.

Turnout gear manufacturers face a challenge in the ever-evolving world of protective textile development and garment design for fire fighters.

The challenge is balance. More specifically providing the optimal balance of the following factors:

  • Protection
  • Comfort
    • Weight
    • Bulk
    • Flexibility
    • Breathability (THL – Total Heat Loss)
  • Durability
  • Price

In the last 5 to 10 years, textile mills and turnout gear manufacturers have worked towards creating fabrics and designing turnout gear that attempt to find that optimal balance .  We have seen advancements improving comfort with lighter and more flexible outer shells and face cloths with high lubricity and moisture wicking.  As systems have gotten lighter, we have seen TPP (Thermal Protective Performance) averages lower slightly to the 38-42 range.

The challenge is balancing these factors as they are inversely related. For example – Increasing TPP often comes with a tradeoff for weight, bulk and reduction in breathability (THL).  The THL average of all the certified composite in the current NFPA 1971 standard is 248.4 with a TPP average of 43.0.

The same inverse relations can be said for fabric strength and its impact to comfort by limiting the THL performance of 3-layer composite systems (outer shell, moisture barrier & thermal liner).  Over the past few years, the industry is seeing stronger outer shells with tensile and tear strength numbers that are 3-4x the requirements in the NFPA 1971 standard.  

Do these higher strength numbers provide more durability and if so, what is the trade-off for the increased strength?  

Based on our years of manufacturing experience, we, at Fire-Dex, believe that at some point, a fabric is strong enough to withstand the demands of the fire service. Exceeding that point can compromise other more important attributes – mainly comfort and THL.

The ultimate goal for TECGEN71 was to create the most flexible, lightest weight, highest THL composite systems in the market without sacrificing thermal protection or durability in the process.  Our focus is to address the leading cause of Line of Duty Deaths since NFPA began tracking in 1979 – Heat Stress.  

TECGEN71 composite systems deliver the highest THLs with high TPPs and durability. Other outer shells have been designed to be stronger,  limiting the ability to deliver the highest THL/TPP combination.  

To better understand fabric strength, let’s dig into industry tests and NFPA requirements.

In summary, TECGEN71, an exclusive outer shell by Fire-Dex, was designed to find an optimal balance of protection, comfort (weight, bulk, flexibility and breathability) and durability. The test data as identified by the NFPA standards reveal that balance. A 3-layer composite system can enjoy high breathability (THL) without sacrificing protection and durability as evidenced by TECGEN71 in combination with DuPont™ Kevlar®/Nomex®.
