Due to the different requirements for the production process of flame-retardant fabrics, the price difference of flame-retardant fabrics is relatively large. Different countries will test fabrics according to different testing standards and regulations. So when we buy flame-retardant fabric, how should we judge whether the flame-retardant fabric is unqualified? Super good, the failure rate of dye fastness is very high. Internationally, especially developed countries and regions have put forward mandatory testing requirements for clothing color fastness indicators. Secondly, the pH value is unqualified, mainly because the molecules of natural fibers such as cotton contain hydrophilic groups such as hydroxyl groups, which have a certain affinity with acids and alkali. If the water washing (neutralization) during the production process is not thorough enough, or the water washing The various finishing agents added during the process are not regulated and controlled, which will cause the presence of acid and alkali residues on the fabric. To test flame-retardant fabrics, you must not only test the flame-retardant properties of the flame-retardant fabrics, but also test the breaking strength and tearing strength, as well as the PH value and formaldehyde content of the fabric. The evaluation of the flame retardant effect of flame retardant fabric is basically to first ignite the flame retardant fabric and burn it for a period of time. When the fabric is far away from the flame, the ease of burning and the propagation speed of the flame are evaluated. Only after combining the above test data can we judge whether the flame retardant fabric is qualified. Textiles have very strict quality requirements for flame-retardant fabrics. From spinning and weaving to dyeing and flame retardant, there is strict monitoring, and any inferior products that are unqualified or not up to standard are resolutely destroyed. This can ensure the production of high-quality fabrics that are responsible for customers and users. There are specialized testing instruments for multi-level testing, allowing customers and users to use high-quality flame-retardant cloth that is healthy and environmentally friendly.
