the method to prevent the bad effect of flame retardant
⑴Reflected form of bad effect flame retardant: after fabric away from fire source, have surplus( flame combustion) or smolder (flameless combustion) phenomenon.
⑵reason for the effect:
①finishing agent ‘s flame retardant effect bad;
②flame retardant agent lower concentration or lower rolling over rate;
③unevenness on fabric padding;
④Technological conditions unreasonable, cause arrangement agent resolve or crosslinking insufficiency.
⑶method for prevention:
①adopt great effect flame retardant agent or adopt different effect of flame retardant and mixed use;
②Make sure fitful flame retardant agent concentration and suitable rolling over rate, keep the fabric of the arrangement agent on the range of 10%~20%.
If higher, it will make the fabric strength lower sharply.
③While padding, both side of the roller need evenness pressure, in case of dapple padding.
④According to flame retardant agent’s property, in case of easy-resolved agent, which will dissolved after high temperature drying, it will make the flame retardant effect lower; and should be fully crosslinking with flame retardant agent.
