FIELD: synthetic fiber production. ^ SUBSTANCE: preparation of composition, which can be used for molding-mediated manufacture of synthetic threads, fibers, and filaments and therefore manufacture of woven, knitted, nonwoven, or napped colored ware, is characterized by that 0.01-0.04% of phosphorus-containing stabilizing additive, 0.10-0.30% of sterically hindered phenol antioxidant, and 0.15-0.5% of light stabilizer are introduced into polymerization medium before or during polymerization, said phosphorus-containing stabilizing additive being selected from phosphorous and hypophosphorous acids and said hindered phenol containing at least one sterically hindered amino group. ^ EFFECT: increased light stability of polyamide ware and avoided significant foaming during polymerization process. ^ 15 cl, 1 tbl, 3 ex |
