Abstract

La présente invention concerne un système ignifuge à expansion pour l'ignifugation de charge d'enveloppe interne de matelas ou d'oreiller et un procédé associé. Des fils ou une toile avec des fibres cellulosiques ou des fibres cellulosiques mélangées avec des fibres chimiques en tant que matière première sont transformés et traités au moyen d'un agent ignifuge inorganique contenant de l'azote et du phosphore, de sorte que les fils ou la toile et l'agent ignifuge inorganique contenant de l'azote et du phosphore constituent le système ignifuge à expansion ; au moyen d'une fonction d'expansion de couverture obtenue lorsque l'agent ignifuge inorganique contenant de l'azote et du phosphore est chauffé, les fils ou la toile ont un pouvoir ignifuge ; les fils ou la toile sont transformés en enveloppe interne d'un matelas ou d'un oreiller, et l'enveloppe interne entoure une charge, de sorte que que, en cas de feu ouvert sur le matelas ou l'oreiller, les flammes ne puissent pas traverser l'enveloppe interne de manière à allumer la charge, et l'ignifugation du matelas ou de l'oreiller est réalisée, qui satisfait à l'essai standard d'ignifugation de matelas America 16CFR1633. Le prix de l'enveloppe interne de matelas ignifuge traitée par le procédé de la présente invention est diminué de moitié par rapport à une enveloppe interne de matelas formée par tissage de fils à âme ignifuges de fibre de verre. De plus, la première est dégradable dans l'environnement naturel après avoir été rejetée, tandis que la fibre de verre contenue dans la deuxième ne peut pas être dégradée naturellement, ce qui peut polluer l'environnement ; par ailleurs, la fumée résultant de la première est évidemment inférieure à celle générée lorsque la deuxième est dans un départ de feu.
