Abstract

The invention discloses a polyurethane fiber dry spinning oil agent, which comprises 30 to 80 weight percent of dimethyl silicon oil, 10 to 50 weight percent of mineral oil, 1 to 7.5 weight percent of high-carbon isomeric fatty alcohol or acid, 1 to 5 weight percent of dispersed component, 0.1 to 1.5 weight percent of stearate and 2 to 20 weight percent of antistatic component. The dispersed component is a mixture of an organic silicon surfactant and acrylic acid-maleic acid copolymer, and the weight ratio of the organic silicon surfactant to the crylic acid-maleic acid copolymer is 1:0.5-2; and the antistatic component is a mixture of polyether silicon oil and nonionic isomeric alcohol polyethenoxy ether, and the weight ratio of the polyether silicon oil to the nonionic isomeric alcohol polyethenoxy ether is 1:0.5-2. The polyurethane fiber dry spinning oil agent has excellent smoothness, softness, antistatic property, stable performance and excellent anti-adherent performance; polyurethane fiber treated by the oil agent has good unreeling property and forming property; and in the subsequent processing flow, polyurethane filaments are easy to unreel, not drop edge and has few broken filaments.

Description

technical field

[0001] The invention relates to a spinning finish, in particular to a spandex dry spinning finish, and also relates to a preparation method of the spandex dry spinning finish. Background technique

[0002] With the ever-changing progress of textile technology, new processes and new technologies for the production of spandex and its products are constantly emerging, especially the vigorous promotion and popularization of DuPont's "cotton + Lycra" technical concept, which has greatly expanded the application field of spandex. It has rapidly expanded from the textile field to automobile decoration, medical and other fields, which has promoted the rapid growth of its market demand and also made the spandex industry develop rapidly in recent years. By the end of 2005, the domestic production capacity will reach 200,000 tons, accounting for about 40% of the world's production capacity. It is expected that by 2010, the market demand will maintain a rapid growth of 1...
