FIELD: chemistry.SUBSTANCE: invention relates to chemical technology of meta-type wholly aromatic polyamide fibres. The fibres contain an ultraviolet absorbent having solubility in water of less than 0.04 mg/l, and which has an exhaustion ratio of the dyed fibres of 90% or more and a light resistance retention ratio after carrier dyeing of not less than 80%.EFFECT: provided meta-type wholly aromatic polyamide fibres that can be dyed in various colours by the carrier dyeing, and in which the detachment of light stabiliser during dyeing can be suppressed.6 cl, 1 tbl, 5 ex |
