The flame retardant reflective cloth comprises a flame retardant cloth base, characterized in that the flame retardant cloth layer is covered with an adhesive layer, an aluminum reflective layer and a high refractive index glass microbead layer from bottom to top, wherein each glass microsphere has a partial sphere To the aluminum reflective layer.
Delayed combustion: refers to the material after leaving the fire to continue the phenomenon of burning fire.
Smoldering: refers to the material to leave the fire, no flame, slow burning phenomenon.
Fold: refers to the material in the ignition process, the material melting or dripping phenomenon.
Arc: is a gas discharge phenomenon, the current through some of the insulating medium generated by the instant spark.
1, to meet the EN533 index 3: according to EN532 implementation of the level of combustion, the test sample after ignition, the flame can not burn to spread to the bottom of the sample with the top or the vertical edge of the fabric; can not have burning debris (droplets) from Cloth on the fall; remove the flame to stop burning, the smoke should not be extended from the carbonized area of the fabric to the fabric of the unbroken area; no holes generated;
The length of any one of the six test specimens shall not exceed 2 seconds.
Water wash before testing requirements:
A. Wash 12 times at 75 ℃ (according to EN ISO 10528 industrial washing method); can also be washed according to customer requirements 5 times, and then tested.
B. Immerse the sample in water (BS 5651: 1978) and dry it five times according to ISO 3175.
This method applies to chemical fiber, cotton and blended fabrics.
2, meet ASTM1506: before washing or dry cleaning, according to D6413 implementation of vertical combustion, continuous burning time up to 2 seconds; 25 times after washing or dry cleaning, according to D6413 implementation of vertical combustion, continuous burning time up to 2 seconds; arc test results The longest continuous burning time is 5 seconds, according to ASTM1959 test.
Washing method: The fabric suitable for washing should be washed 25 times with the American Textile Association's method AATCC 135.
3, to meet the NFPA1971 multi-layer structure of the standard fire service. The overall protective clothing thermal protection performance TPP value can not be less than 35 (cal / cm2); the whole clothes to do penetration test, can not have liquid leakage; clothing shell, lining, life-saving equipment and other components through vertical combustion, Can not exceed 100mm, the average delay time can not be more than 2 seconds, and can not have droplets.
Principle of action editor.
Reflective reflective cloth in the reflective part of the use of high refractive index of glass beads back to the principle of reflection, through the post-processing of advanced processing technology made. It can reflect the distant light back to the light, both in the day or night have a good retroreflective optical performance. Especially at night, can play the same as the day of high visibility. The use of this high-visibility flame retardant reflective cloth made of safety clothing, whether the wearer is in the distance, or in the light or scattered light interference, can be relatively easily found by other rescuers.
