| titleOfInvention | Easy-dying meta-type wholly aromatic polyamide fiber and method for producing the same |
| abstract | An easily dyeable meta-type wholly aromatic polyamide fiber having excellent dyeing properties for a dye and having both fiber strength and heat shrinkage stability, and a method for producing the same. An amide-based solvent solution of a meta-type wholly aromatic polyamide is spun into an aqueous coagulation solution containing an inorganic salt and coagulated. The coagulated yarn is washed with water, stretched 1 to 4 times in a warm water bath, The inorganic salt in the fiber is removed in a warm water bath, and then the stretched by saturated steam under the conditions satisfying the following (a) to (d), and further subjected to a heat treatment in a state where tension is not applied, and a cutting strength of 3.5 to 5 cN / Dtex, easily heatable meta-type wholly aromatic polyamide fibers having a dry heat shrinkage of 300 ° C. of 10 to 30% and a wet heat shrinkage of 135 ° C. of 0 to 12%. (A) The content of the amide solvent in the fiber before drawing in steam is 3 to 25% by weight. (B) Saturated steam pressure during stretching in steam is 29.4 to 392 kPa (C) Total draw ratio of hot water stretching and stretching in steam is 4 to 6 times (d) Stretching time of stretching in steam is 1 second to 2 minutes [selection diagram] None |
