Fire prevention and parameters of the application of functional fabrics

fire prevention and parameters of the application of functional fabrics
Either in life or on TV, you should have seen the brave firefighters discrepancy among the fire scene. Don't you wonder why in the raging fire and firefighters not burn or scald by the fire? The reason is very simple, because they wear uniforms are made of fireproof functional fabrics, able to withstand the high temperature is not fire, keep your clothes in the performance of the fabric.
Fire functional fabrics have good washing resistance, non-toxic, odorless, safe to human body, air permeability, soft and comfortable. Apply to metallurgy, machinery, forestry, fire and other industries to make Flame retardant protective clothing, can also be used in hotels, restaurants, karaoke bars theatre of decorative cloth.
Product main features:
Fire functional material production line adopts the United States dupont KEVLAR fiber twisting. KEVLAR has high strength, more than 28 grams/denier, 5-6 times that of high quality steel, modulus of 2-3 times that of steel or fiberglass, toughness is 2 times that of steel, and the weight is only 1/5 of the steel. Fire the continuous use of functional fabrics very wide temperature range, in - 196. C to 204 ℃ scope can normal operation for a long time. Shrinkage rate to zero under the condition of 150 ℃, 560 ℃ high temperature decomposition not melt.
Fire functional fabric line has the following features:
1. High strength 20.92 CN/DTEX;
2. The linear density: 1.667, heavier than water, drowned in the water;
3. The cutting resistance, good thermal stability, don't melt at high temperature, the glass transition temperature of about 345 ° C;
4. Bending performance generally, tie yi form burr;
5. Good tensile performance, elongation at break: 3.55%;
6. Resistant to common organic solvents and salt solution, strong acid, strong alkali resistance is poor;
7. Sensitive to uv light, long time exposure to the sun, the intensity attenuation about 40%;
8. Yellow appearance
9. The price is relatively cheap;
10. Fire functional fabric cloth can be made according to the requirements of high strength of resistance to high temperature cloth
Commonly used low toxicity standards:
REACH - SVHC (adjacent stupid formate (6 p) amount below 1000 parts per million (PPM)
Generic brands
Total lead content below < 90 PPM
The total organic tin < 1 PPM
ROHS formaldehyde < 50 PPM
Eight heavy metal (EN71-3) total lead content within less than 200 PPM to 90 PPM
Formaldehyde < 75 PPM
Azo AZOFREE < 30 ppmaeicg4a
