Abstract
The present invention relates to the technical field of fiber production and provides a method for preparing a polyolefin fiber and a product and use. The preparation method comprises the following specific steps: S1. mixing a silane coupling agent, a dispersant and an organic solvent to obtain a treatment solution; S2. uniformly dispersing the treatment solution on a fully dried ceramic fiber and high-speed stirring, wherein the ceramic fiber is a mixture of nanoscale alumina, microscale alumina, nanoscale silica and microscale silica; and S3. high-speed premixing a polyolefin powder and the treated ceramic fiber to obtain an anti-cutting functional masterbatch, and then melt spinning the same to obtain the polyolefin fiber. The method of the present invention enables significant improvement of the strength, wear resistance, softness, comfort, moisture absorption and permeability of the prepared polyolefin fiber, thereby greatly improving the anti-cutting performance, hand feel and comfort of the polyolefin fiber.
