Problems solved by technology

However, when using these conventional plasmas to treat materials, because the plasma conditions are significantly affected by changes in electric field strength and pressure, the electron energy in the plasma has a wide distribution and contains some high-energy particles, which will cause plasma dissociation and make the material properties Deterioration occurs

Abstract

The invention relates to a method for performing the surface modification of polyester fiber materials, in particular to a method for performing the surface modification of polyester filaments by remote plasmas. The method comprises the following steps of: vacuumizing plasma equipment, introducing sulfur dioxide and oxygen in a reasonable volume ratio into the plasma equipment simultaneously, anddischarging to generate the plasmas under the action of an electric field, wherein the generated plasmas react on the surfaces of the materials to be modified to achieve the effect of modification. The method is characterized in that the modified polyester filaments are put in the downstream along the direction of airflow and have a certain distance away from a plasma discharging area. Aiming at the problem of the conventional plasmas in the process of the surface treatment of the polyester fibers, for example, the performance of fiber materials is deteriorated due to the bombardment of high-energy particles on the surfaces of the fiber materials in modifying, so the treatment method of the remote plasmas is provided. The surfaces of the materials are modified by the treatment of the remote plasmas, and other performance keeps stable basically.

Description

technical field [0001] The invention relates to a method for surface modification of polyester fiber materials, in particular to a method for remote plasma surface modification of polyester long fibers, specifically a remote plasma one-step surface modification method for polyester long fibers sexual method. Background technique [0002] Plasma is the fourth state of matter, which is composed of a large number of electrons, cations, and free radicals. These microscopic particles with high activity and high energy can interact with the surface of the material, thereby endowing the material without changing the bulk properties of the material. With new properties, such as adhesion, reactivity, biocompatibility, water absorption, etc., the field of use of materials can be greatly expanded. At present, low-temperature plasma modification is commonly used in the field of material modification. Usually, under vacuum conditions, capacitive or inductive excitation is used to genera...
