Embodiment 1

[0022] A piece of polyester jeanette colored fabric (width, 1.5m long) is inserted between the electrodes of the existing atmospheric pressure plasma equipment, the power is turned on, and a voltage is applied to carry out corona discharge treatment. Use 100W power for 30s discharge treatment, the discharge frequency is 13.56MHZ. Table 1 is a comparison of the main performance indicators between the normal pressure plasma treatment of Example 1 and the conventional polyester jeanette fabric softening and decontamination finishing.

Abstract

A normal-pressure plasma treating method for post-finishing of fabrics is disclosed by the present invention, which relates, in particular, to a normal-pressure plasma treating method for softening and decontaminating finishing of fabrics without chemical assistants and belongs to the technical field of textile processing. The present invention is characterized in that a fabric is positioned between electrodes of a plasma device and treated with corona or glow discharge for 3s-20min by voltage application after the power is switched on,. The fabric can be a natural fiber fabric, a synthesized fabric, a regenerated fiber fabric, a blended fabric of the above fabrics or an interwoven fabric of the above fabrics. The present invention has simple operation and short process and is free of the troublesome steps including padding, pre-baking and baking; without use of chemical assistants or water, the present invention is conducive to environment protection; the fabrics finished with the present invention feels soft and smooth.

Description

technical field [0001] The invention relates to an atmospheric pressure plasma treatment method for fabric post-finishing, in particular to an atmospheric pressure plasma treatment method for softening and decontaminating fabrics without chemical additives, which belongs to the processing of textiles technology field. Background technique [0002] With the improvement of people's living standards, clothing pursues lightness, elegance and comfort. In the process of textile processing, the fabric undergoes various chemical additives and wet and heat processing to withstand various mechanical forces, so that the fabric structure and The shape of the fiber changes, and the oil and wax in the natural fiber and the oil on the synthetic fiber are all removed, causing rough and stiff hand feeling. [0003] After the rapid development of synthetic fibers in recent years, their varieties and output are constantly increasing. These fibers are generally treated at high temperature, and...
