The following apparatus described in "Journal of the Textile Machinery Society", Vol. 38, No. 4, page 188 (1985) can be used. This device has a structure in which a pair of electrodes for discharge are installed in a vacuum vessel that can maintain a low pressure, a specific gas can be introduced at a predetermined flow rate, and the inside of the vessel is evacuated by an attached vacuum pump to maintain a constant pressure. It is a device having performance. When a voltage is applied to the electrodes in this device, a glow discharge occurs, and the introduced gas becomes a low-temperature plasma state. Most commonly, 13.56 MHz high frequency power is applied. By passing the fabric to be treated in a low-temperature plasma atmosphere formed between the electrodes at a desired speed, the fabric can be subjected to a low-temperature plasma treatment.

確ではないが，本発明者らは次のように推測している。(Action) As in the method of the present invention, if a cellulose fiber fabric is subjected to a crosslinking treatment with a cellulose-reactive resin and then subjected to a low-temperature plasma treatment, it is possible to impart excellent water absorption performance and its durability. The reason is not always clear, but the present inventors speculate as follows.

然的に洗濯耐久性を有するようになる。It is well known that a low-temperature plasma treatment introduces a hydrophilic group to the fiber surface and improves water absorption. On the other hand, considering the capillary phenomenon which is one of the factors of water absorption, the capillary inside the fiber is considered. In addition to the above, a capillary tube between fibers and between yarns can be considered. However, in the method of the present invention, the non-crystalline region is cross-linked by the fibrin-reactive resin and the resin partially penetrates into the non-crystalline region. Since the hydrophilic groups are introduced to the fiber surface by low-temperature plasma treatment after the capillary is modified into a capillary, the capillary phenomenon from the hydrophilicized fiber surface to the inside or between the fibers is promoted, and only the low-temperature plasma treatment is performed. It is presumed that it will exhibit superior water absorption performance as compared with the ones. In addition, since both the action of the cellulose-reactive resin and the action of the low-temperature plasma bring about a semi-permanent effect, the water absorption performance in the present invention necessarily has washing durability.
