    Nyckelord :Aftertreatment; flame retardant; free formaldehyde; tetrakis hydroxymethyl phosphonium chloride THPC urea pre-condensate; ammonia curing; sodium metabisulfite; resorcinol; diethylene glycol; boric acid; curing; oxidation;

    Sammanfattning : This thesis aims at developing a method of chemical aftertreatment for reduction of free formaldehyde release of a tetrakis (hydroxymethyl) phosphonium chloride (THPC) urea precondensate, ammonia cured durable flame retardant finished cotton fabric, by preventing the formation of free formaldehyde. Formaldehyde is toxic and carcinogenic. LÄS MER

  4. 3. NFC-Spore Biocomposites : A study of flame retardancy, density, mechanical properties and production of films

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Tomas Romson; Victor Goch; [2014]
    Nyckelord :Lycopodium; Nanofibrillated cellulose; Mechanical properties; Flame retardancy; Film production;

    Sammanfattning : Sporopollenin is considered a resistant material and might be applicable in flame retardant material. The use of renewable material in fields mainly dominated by toxic materials, such as bromides in flame retardant materials, could greatly improve the sustainability in those fields. LÄS MER
