Dry antistatic spandex spinning oil and preparation method thereof

Abstract

The invention discloses dry antistatic spandex spinning oil, which is prepared from a compound high-temperature smoothing agent, a compound antistatic agent, a phenolic antioxidant, a phenylamino antioxidant, a gadoleic acid antioxidant, a high-temperature dispersant, a softening agent, an environment-friendly emulsifier, metallic stearates, a preservative and a defoamer, wherein the compound high-temperature smoothing agent is prepared by compounding hydrogenated paraffin base oil, hydrogenated naphthenic base oil and methyl silicone oil. The invention further provides a preparation method ofthe dry antistatic spandex spinning oil. According to the dry antistatic spandex spinning oil, spandex spinning has excellent antistatic property in different humidity conditions and is suitable forhigh-speed spinning process requirements of spandex denier filaments of various specifications. The dry antistatic spandex spinning oil has good smoothness, excellent high and low temperature resistance and excellent yellowing resistance, and has good dispersion and isolation to spandex at the same time.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a dry-process spinning oil, in particular to a dry-process antistatic spandex spinning oil and a preparation method thereof. Background technique [0002] Polyurethane elastic fiber is what we commonly call "spandex" for short. Because of its excellent elasticity and good comprehensive performance, it is called an indispensable "MSG-like" textile raw material for the modern textile and garment industry. Due to its excellent fracture Elongation and breaking strength can be used for all fabrics that require good elastic recovery, so it has high application value and good development prospects. Spandex spinning processes mainly include dry spinning, melt spinning, wet hair spinning and reaction spinning, etc. Among them, the output of dry spinning reaches 80% of the world's total spandex production, which belongs to the main spinning method, and its typical representative is INVISTA c...
