Abstract

The invention discloses a dry-process antistatic spandex spinning oil, which consists of a composite high temperature smoothing agent, a composite antistatic agent, a phenol-based antioxidant, an anilino antioxidant, an alkenoic acid antioxidant, a high temperature dispersant, a soft The compound high-temperature smoothing agent is composed of hydrogenated paraffin base oil, hydrogenated naphthenic base oil and methyl silicone oil. The invention also provides a preparation method of the above-mentioned dry antistatic spandex spinning oil. The invention enables spandex spinning to have excellent antistatic properties under different humidity conditions, and is suitable for high-speed spinning process requirements of spandex deniers of various specifications. The invention has good smoothness, excellent high and low temperature resistance, excellent yellowing resistance, and has good dispersion and isolation properties for spandex.

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, which is our conventional abbreviation "spandex", is called as an indispensable "MSG-like" textile raw material in the modern textile and garment industry due to its excellent elasticity and good comprehensive properties. Elongation and breaking strength can be used for all fabrics that require good elastic recovery rate, so it has a good development prospect with high application value. Spandex spinning processes mainly include dry spinning, melt spinning, wet spinning and reaction spinning, etc. Among them, the output of dry spinning reaches 80% of the total output of spandex in the world, which is the main spinning method, and its typical representative is INVISTA The company's Lycra fiber and Baye...
