1results about How to "Adjustable volume" patented technology

This invention provides antistatic fibers, their preparation methods, and methods for adjusting their fineness and / or volume resistivity, belonging to the technical field of functional fibers and their preparation methods. The first type of antistatic fiber includes a fiber body made of a conductive composition. The second type of antistatic fiber includes a core layer and a sheath layer, with the sheath layer covering the outside of the core layer. The core layer is made of a conductive composition, and the sheath layer is made of a fiber-forming polymer. The preparation method of the first type of antistatic fiber can produce the first type of antistatic fiber; the preparation method of the second type of antistatic fiber can produce the second type of antistatic fiber. The method for adjusting the fineness and / or volume resistivity of the first type of antistatic fiber includes adjusting the types and mass ratios of the components in the sheath layer and the core layer during the preparation process of the first type of antistatic fiber, so that the obtained antistatic fiber has a set fineness and / or volume resistivity. This method can produce antistatic fibers with excellent antistatic properties.
