| titleOfInvention | A kind of fire-retardant Nylon 6 fiber and preparation method thereof |
| abstract | The present invention relates to a kind of fire-retardant Nylon 6 fiber and preparation method thereof, the present invention first by hydroxymethyl phenyl phosphinic acid, thionyl chloride and ether according to certain mol proportion reacting by heating in a kettle., the chloromethyl phenyl phosphinic acid prepared after completing are passed through ammonia in sodium hydroxide solution to carry out aminating reaction and prepares aminomethyl phenyl phosphinic acid, it is polymerized fire-retardant Nylon 6 by nylon polymerization monomer caprolactam, aminomethyl phenyl phosphinic acid and polyalcohol catalyst again, finally dry fire-retardant Nylon 6 is prepared fire-retardant Nylon 6 fiber through melt spinning.The fire-retardant Nylon 6 fiber of the present invention contains 0.5～15% fire retardant aminomethyl phenyl phosphinic acid of mass；The limited oxygen index of fire-retardant Nylon 6 fiber is 30～35, and filament number is 0.5～4.0dtex, and fracture strength is 2.5～5.0cN/tex.The fire-retardant Nylon 6 flame-retardant fiber of the present invention is good, and fire retardant addition is few, does not affect the mechanical strength of nylon 6 fiber, effectively expands the use field of nylon 6 fiber. |
