In fine wools, differences of around 150 cents can often be seen between a very low mid-break of single figures, and a mid-break in the 80 to 90% range. Part four includes case studies of major applications of fire resistant textiles. Whilst cotton catches alight at 255°C, the temperature must reach 570-600°C before wool will ignite; while polyester melts at 252-292°C and nylon succumbs at an even lower 160-260°C, wool never melts so it can’t stick to the skin like many common synthetics. The so-praised aspect of alpaca wool is that it is much more fire-resistant than other fabrics. The reason for this is that each and every wool fiber retains a certain amount of air moisture, even wool that’s several years old. Due to the huge number of its advantages, it has unlimited application. fire resistant materials 1. fire resistant materials submitted by:- riddhesh rajendra varik 15sa31 t.y.b.arch st.wilfred’s institute of architecture 2. index sr.no title pg.no 1 bricks 2 timber 3 concrete 4 mineral wool 5 gypsum board 6 asbestos sheets 7 perlite boards 8 calcium silicate boards 3.
