Because of the different requirements of flame retardant fabric production process, the price difference of flame retardant cloth is relatively large. Different countries will inspect fabrics according to different testing standards and regulations. Then, when we buy flame retardant cloth again, how should we judge that the flame retardant cloth is unqualified?
First, the rate of disqualification of color fastness is very high. In the world, especially in developed countries and regions, the requirements of the color fastness test have been put forward. The second is the pH value not qualified, is mainly due to the molecular cotton and other natural fibers containing hydrophilic groups such as hydroxyl, acid and alkali, have a certain affinity, if the water in the production process (neutralization) is not thorough enough, or all kinds of washing process to add finishing agent not regulate control, will cause the existence of acid and alkali residue fabric.
The flame retardant fabric should be tested not only for the flame retardancy of flame retardant fabrics, but also for breaking strength and tearing strength, as well as the pH value and formaldehyde content of fabrics. The flame retardant effect of flame retardant cloth is basically ignited flame retardant cloth burning for a period of time, when the fabric away from the flame, to assess the degree of combustion difficulty and flame propagation speed. It is impossible to determine whether the flame retardant fabric is qualified after comprehensive inspection data above.
Xinke protective is very strict to the quality of flame retardant cloth. From the spinning and weaving to dyeing of flame retardant are strict monitoring, have not qualified or not qualified quality products so that resolutely destroyed, made responsible for the customer, the user is responsible for the quality of cloth. There are special testing instruments for multi-level testing, allowing customers and users to use healthy, environmentally friendly high-quality flame retardant cloth.
