However, when this method is used, it is a method of soaking in a treatment bath of 4.0-4.0% Yaburiba solution at a temperature of 95-140°C and a treatment time of 20 minutes to 2 hours, followed by moist heat treatment. (1) Regarding pH concentration, there is a limit on j-1 acidity of pH≧2.5, which is a constraint when it is desired to impart remarkable anti-build properties to cationically dyeable polyester fibers. (2) The treatment temperature can also be limited to a range of 95 to 140° C. due to the acidity and treatment time. (3) The processing time is very long, requiring 20 minutes to 2 hours, and is incompatible with 3M's current trend of increasing speed and improving productivity.

。The treatment temperature with the acidic aqueous solution must be 1.145° C. or higher. If the temperature is not yet 145°C, the processing time can be shortened by 9 times. The greatest feature of the present invention is that the reforming treatment can be carried out quickly at high temperatures and within a short period of time. It is necessary to use high frequency heating for heating during tS of the reforming treatment. In normal contact heating using electric heat, the heating plate is easily softened by acid and cannot withstand 1111 (dI) for a long time.

Since it varies depending on the degree of processing M, the optimum required time should be determined as appropriate from the combination K of these payment factors, but the time in the range of 0.1 to 10 minutes is my own. 0. If the temperature is less than 145℃, the temperature of the fiber and the acidic aqueous solution in which the fiber is soaked is 145℃.
It is difficult to raise the temperature to a temperature higher than 2, and therefore it is not desirable to impart building properties to the fibers.
