What are The Testing Standards for Qualified Flame Retardant Fabrics?

Flame retardant fabric is a protective fabric with relatively complicated production process. It is necessary to test the performance of flame retardant fabric. Ordinary naked eyes cannot tell the quality and grade of the fabric. It must be tested by professional testing equipment to identify the pros and cons. Burning cloth is a special fabric that can delay the burning of flames. It is mainly used to make protective clothing, special protective clothing and industrial fabrics. It is widely used in metallurgy, machinery, mining, chemical, fire, clothing, petroleum, electric power, natural gas, coal. , aviation, shipping and other industries. So, what is the standard for the detection of qualified flame retardant fabrics? What kind of flame retardant fabric products are qualified flame retardant fabrics?

Compared with the shrinkage test and color fastness test of common fabrics, the test requirements of flame retardant fabrics are more complicated because some of their technical features are difficult to test, measure and quantify. The flame retardant grade of the flame retardant fabric is the level of the property that the material has or the material has been treated to delay the spread of the flame, and the hierarchy is classified. Key indicators of the level: burning speed, time away from fire (how long after the fire is extinguished, domestic time is called refueling time), smoldering time. The flame retardancy of the flame retardant fabric is judged by the burning rate of the fabric. That is, the fabric that has been flame-retarded is in contact with the flame for a certain period of time according to a prescribed method, and then the flame is removed to measure the time during which the fabric continues to have flame burning and flameless burning, and the extent to which the fabric is damaged. The shorter the time of flame burning and the time of flameless burning, the lower the degree of damage, the better the flame retardant performance of the fabric; on the contrary, the flame retardant performance of the fabric is not good. Testing flame retardant fabric is not only to test the flame-retardant performance of the flame retardant fabric - the flame-retardant effect evaluation of the flame retardant fabric is basically to first ignite the flame retardant fabric (or put it in flame) for a period of time After that, the degree of combustion difficulty and the speed of flame propagation were evaluated; the breaking strength and tear strength test were also carried out, as well as the pH and formaldehyde content of the fabric. After the above various test data are combined, it can be judged whether the quality of the flame retardant fabric is passed.

Therefore, if a professional manufacturer of flame retardant fabric can detect the flame retardant performance of the flame retardant fabric, it can accurately grasp the performance of its own products and better produce qualified high-quality flame retardant fabric. Flame retardant fabric buyers must choose professional manufacturers, manufacturers with professional flame-retardant testing rooms should be given priority.
