PROCESS FOR PREPARING NYLON-6-FIBER HAVING GOOD DYEING AND ANTISTATIC PROPERTY

摘要

The nylon 6 fiber having excellent dyeing property and antistatic property is prepd. by add-mixing and reacting caprolactum, water and 0.3-10 mole% of the copolymonomer of formula R-(COOH)2 (I) and 2-15 wt.% of polyethylene glycol diamine at 230-280 deg.C for 5-12 hrs.; inputting and reacting a diamine of formula R'-(NH2)2 (II) of 13 times amt. w.r.t. amt. of the copolymonomer (I) at 250-280 deg.C for 20-30 hrs. and making a chip and extracting, drying; then solid-phase polymerizing that at 160-195 deg.C for 15-25 hrs. to form 2.40-2.70 viscosity (R.V) and 15-30 meq/kg of NH2 concentration of the solid-phase polymer; then melt-spinning that. In formulas, R is gp. of formula (1) or (2); R' is C2-C8 hydrocarbon gp. of formula (3), (4) or (5); M is Li, Na or K.
