Problems solved by technology

However, the general antistatic performance is poor, and it cannot solve the static electricity problem in the subsequent weaving process.
For example, the patent CN104372446A uses a quaternary ammonium salt cationic surfactant as an antistatic agent and adds it to the oil agent, which has a certain antistatic performance, but still cannot fully meet the weaving needs; the patent CN101525788 uses a mixture of polydimethylsiloxane and phosphate As an antistatic agent, it is added to the spinning dope to make the product have antistatic properties, but it consumes a lot of raw materials, has high cost and complicated process, which is not conducive to implementation.

Abstract

The invention discloses ultra-strong antistatic spandex spinning oil and a preparation method thereof. The ultra-strong antistatic spandex spinning oil is prepared from 40 to 80% mass of polydimethylsiloxane, 5 to 30% mass of white oil, 1 to 10% mass of organosilicon quaternary ammonium salt, 0.1 to 10% mass of metallic stearate and 0.1 to 10% mass of graphene, wherein the percentage content is the mass percentage of the component content to the total oil mass. The novel material ultra-strong antistatic graphene is mixed into the spandex spinning oil, and the prepared spandex spinning cake has good formation, is easy to unwind and has strong antistatic property.

Description

technical field [0001] The invention relates to a new type of oil agent used in the spandex dry spinning process. The oil agent of the invention not only makes the spandex yarn have good forming and unwinding performance, but also has super strong antistatic property. Background technique [0002] Spandex (polyurethane) fiber is the most elastic synthetic fiber at present. It has excellent elongation at break and breaking strength. It is an indispensable special textile fiber in the production of high-grade textiles. It has high application value and Good development prospects. Dry spinning is a widely used spandex production process at present. It needs to oil the spandex yarn, so that the spandex yarn has good smoothness and clustering during the forming process, and it is easy to unwind and not collapse during later use. , There are few broken wires at the bottom, and at the same time, certain antistatic properties are given to the spandex yarn. [0003] At present, the...
