Prevention methods for poor flame retardant effect
⑴Flame retardant Poor performance: After the fabric leaves the fire source, there is afterburning (flame burning) or smoldering (flameless burning). .
⑵Causes:
①The flame retardant effect of the finishing agent is poor;
②The flame retardant concentration is too low or the rolling residue rate is too low;
③ The fabric is unevenly padded;
④The process conditions are unreasonable, resulting in the decomposition of the finishing agent or insufficient cross-linking.
⑶ Prevention methods:
①Choose Flame retardant Flame retardants with excellent effects or a mixture of flame retardants with different flame retardant effects are used;
② Determine the appropriate flame retardant concentration and appropriate rolling method The remaining rate is to keep the finishing agent content on the fabric between 10% and 20%. If it is too high, the strength of the fabric will be greatly reduced.
③When padding, the pressure on the left and right sides of the rollers should be uniform to prevent uneven padding.
④ Determine the appropriate finishing process according to the properties of the flame retardant to prevent the easily decomposable finishing agent from decomposing due to excessive drying temperature, thereby reducing the flame retardant effect. Reduce; for durable flame retardants, ensure sufficient cross-linking.
