Abstract

The invention discloses a polyurethane fibre spinning oil. Its composition includes (by wt%) 5-80% of mineral oil, 10-75% of silicone oil, 0.5%-30% of epoxyethane and epoxypropane copolyether, 0.5%-50% of polyether silicone oil, 0.5-15% of antistatic agent and 0.1-10% of anti-sticking property improving agent.

Description

technical field [0001] The invention relates to an oil agent for synthetic fibers, in particular to an oil agent for spandex spinning. Background technique [0002] Elastic fiber, that is, polyurethane fiber, is called spandex in China, because it has excellent elasticity, good dyeability, low density, high strength, high elongation, good resilience, light resistance, wear resistance and corrosion resistance, etc. It is widely used in swimwear, high-grade knitted underwear and clothing fabrics, etc., and its development is very rapid. Since Yantai built the first 300-ton / year industrialized device in the 1990s, the domestic spandex annual output has reached 100,000 tons, and the oil agent used has reached more than 6,000 tons. The spandex spinning processes mainly include dry spinning, melt spinning, and wet spinning. In method spinning and reaction spinning, etc., the oil agent is applied to the surface of the fiber through the tanker or nozzle, so that the fiber has good ...
