Abstract

The invention discloses a conductive spandex and a production method. The production method attaches a layer of melt-spun spandex skin layer containing a certain proportion of conductive particles on the outside of the dry-spun spandex, so that the polyurethane elastic fiber can maintain high elongation and high resilience. At the same time, it has good electrical conductivity. Fabrics using conductive spandex have good antistatic properties. The conductive spandex produced by this method has excellent durability and stability, and friction, bending and washing have no effect on its conductive performance.

Description

technical field [0001] The invention relates to a synthetic fiber and a preparation method thereof, in particular to a conductive spandex fiber and a preparation method thereof. Background technique [0002] With the rapid development of synthetic fibers, synthetic fibers account for an increasing proportion of chemical fiber applications. However, there is a problem in the practical application of synthetic fibers, that is, it is easy to accumulate static electricity. Static electricity will cause textiles to absorb dust during use, fluff and pilling, and clothing will entangle the human body and cause discomfort. The scientific name of spandex is polyurethane fiber. As a kind of synthetic fiber, it has excellent elastic properties and is known as the "MSG" of textiles. Adding a small amount of spandex to the fabric can greatly improve the wearing performance of the final product, but spandex also has the problem of accumulating static electricity . [0003] The commonly...
