Method and system for preparing nanofiber coating on surface of yarn or fiber bundle

Abstract

The invention discloses a method and a system for preparing a nanofiber coating on the surface of a yarn or a fiber bundle and belongs to the field of the textile industry. The method includes: arranging a spinning sprayer and a collector oppositely by a certain distance so that the yarn or the fiber bundle passes through between a nozzle of the spinning sprayer and the collector; continuously supplying spinning solution into the spinning sprayer by the aid of an automatic solution delivery device, enabling the collector to be grounded, applying high-voltage direct current on the spinning sprayer, and generating electric field force between the spinning sprayer and the collector; and controlling the high-voltage direct current on the spinning sprayer, enabling the electric field force between the spinning sprayer and the collector to be larger than surface tension of the spinning solution at the nozzle of the spinning sprayer, and enabling the spinning solution in the spinning sprayer to be sprayed out of the nozzle of the same by jet flow to be coated on the surface of the passing yarn or the passing fiber bundle so that a nano coating is formed, and the yarn with the nano coating formed on the surface is a prepared nano fiber. The method is simple in process steps, good in controllability and capable of producing nano fibers uniform in diameter distribution and excellent in performance with low cost.

Description

technical field [0001] The invention relates to the field of textile industry, in particular to a method and system for preparing nanofiber coating on the surface of yarn or fiber bundle. Background technique [0002] In the textile industry, the yarn is usually coated with a functional layer by sizing process to enhance the stability, wear resistance and corrosion resistance of the yarn, or to make the yarn have different colors. The sizing process is specifically the process of applying sizing to the warp yarns to improve their weavability. Weavability refers to the performance of warp yarns that can withstand repeated friction, stretching, bending, etc. of warp stoppers, healds, reeds, etc. on the loom without fluffing or even breaking. Unsized single yarn fibers do not cohere firmly with each other, and the surface has more hairiness, making it difficult to weave. On the one hand, sizing should allow the size to penetrate into the yarn, so that the fibers are entwined ...
