Document Type and Number:
WIPO Patent Application WO/2019/022532
Kind Code:
A2
Abstract:
An additive slurry for polyurethane-urea elastic fiber production according to the present invention includes: a solvent; a functional additive; and a moisture removal agent. According to the additive slurry for polyurethane-urea elastic fiber production according to the present invention, the moisture removal agent is introduced and added such that moisture that can enter the additive slurry can be removed to prevent in advance the infiltration of moisture into a spinning solution due to the additive slurry, thus suppressing gel formation in the spinning solution and a reduction in the quality of the polyurethane-urea elastic fiber due to moisture can be prevented.
