A method for manufacturing a flame-resistant (FR) textile for protective clothing, particularly for firefighters, is disclosed by Trans-Textil of Freilassing, Germany. In addition to being highly FR, Trans-Textil says that the textile reduces the amount of physiological stress, in particular heat stress, to which its wearer is subjected in comparison with conventional FR textiles. The material also has improved breathability and a lower weight, the company claims. Outlined in US Patent Publication 2018/0223473, the material is generally formed of a textile layer that contains several different fibre components and is subjected to a treatment step in which at least one of the fibres is extracted or at least partially detached from the textile layer. This results in the formation of air chambers that provide additional insulation and protection against heat and flames, while at the same time significantly reducing the weight of the material, enableing the optimal transport of moisture away from the wearer and also providing a wide variety of design options, Trans-Textil claims.
