Description

Plasma treatment equipment for whole roll of fabric

Technical Field

The utility model relates to a plasma treatment's technical field, specifically speaking is a plasma treatment equipment of whole book fabric.

Background

With the rapid development of high-performance structural material technology and advanced material processing technology, people put higher demands on toughness, rigidity, environmental protection, recycling property, service life and the like of materials. Therefore, the surface treatment of the material to improve various properties of the material by changing the form, chemical composition, texture, etc. of the material surface has been rapidly developed in recent years. Among various surface treatment methods such as physical treatment, chemical treatment, mechanical treatment and the like, the plasma surface treatment technology is rapidly developed due to the advantages of high cleaning efficiency, low energy consumption, no waste and the like. At present, aiming at different industrial applications, the plasma treatment under different conditions has been obviously divided, large-area natural or synthetic materials needing continuous treatment are generally treated by normal-pressure plasmas, and semiconductors, biomedical materials and the like are generally treated by low-pressure plasmas.

The traditional 'wet' fabric treatment process has high temperature, long time, high labor intensity, certain chemical pollution and low efficiency. The modern process adopts a 'dry method' plasma treatment technology to interact the surface of the fabric or the fiber with plasma to achieve the cleaning and activating effects of the surface of the fabric, thereby greatly improving the moisture absorption and other properties of the fabric, reducing the temperature of the whole process, shortening the time, reducing the labor intensity, eliminating the pollution and obtaining more remarkable effects than the conventional chemical treatment process.

One is to perform continuous plasma treatment on the fabric under atmospheric pressure, and this method needs high voltage to realize discharge, and the discharge temperature is high, and it is unable to effectively treat the heat-labile fabric, and the area of treating the fabric in unit time is limited, and it is unable to improve the production efficiency. The other method is that the whole roll of fabric is placed in a reaction bin in advance, plasma treatment is carried out on the fabric under the low-pressure environment of 10-100 Pa, the fabric is treated in a mode that the fabric is unfolded from a discharging roller, passes through a discharging area and then is received by a receiving roller, and stable glow discharge can be achieved in the mode.

The reason why the treatment effect of the inside and the surface of the fabric is not uniform is that the flowing direction of the reaction gas is along the surface of the fabric during the treatment, and the reaction gas does not uniformly reach the inside of the fabric, so that the reaction gas components on the inner and outer surfaces of the fabric are not uniform although uniform discharge is achieved, resulting in a large difference in the treatment effect in the thickness direction of the fabric. Therefore, the technical problem to be solved by those skilled in the art is how to provide a stable glow discharge environment, and to enable the reaction gas to uniformly flow through the thickness direction of the fabric to achieve uniform plasma treatment on the entire roll of fabric, and to ensure the working efficiency and the uniformity of the plasma treatment on the entire roll of fabric.
