Method for producing functional polyester fiber, and polyester products using functional polyester fiber

[0098] First, as the first process, a predetermined amount of water, 5% owf sodium hydroxide, and 2% owf benzyl alcohol as a penetrating agent were put into a high-pressure liquid flow dyeing machine that added polyester fibers, and carried out at room temperature for 5 Minutes of treatment, followed by heating to 95 ° C for 40 minutes of treatment.

[0099] After the first process is terminated, the inside of the tank is drained and washed with water, and then the second process is performed.

[0100] As the second step, 20% owf of 2,6-dichloro-4-(3-sulfoanilino)-homonium was put into the high-pressure liquid-flow dyeing machine that had been treated in the first step and added polyester fibers. Triazine 10% aqueous solution, Glauber's salt 15g / L, soda 5g / L and baking soda 5g / L, after 5 minutes of treatment at room temperature, heat treatment at a temperature of 1°C per minute between 20°C and 30°C, The first substitution reaction occurs between the reactive group attache

[0104] First, as the first process, a predetermined amount of water, 5% owf ethylenediamine, and 2% owf benzyl alcohol as a penetrating agent were put into a high-pressure liquid flow dyeing machine with polyester fibers, and carried out at room temperature for 5 Minutes of treatment, followed by heating to 95 ° C for 40 minutes of treatment.

[0105] After the first process is terminated, the inside of the tank is drained and washed with water, and then the second process is performed.

[0106] As the second step, a 10% aqueous solution of 2,6-dichloro-4-oxo-s-triazine Na salt at 20% owf was put into a high-pressure liquid flow dyeing machine filled with the polyester fiber treated in the first step. , Glauber's salt 15g / L, soda 5g / L, and baking soda 5g / L, after 5 minutes of treatment at room temperature, the temperature was raised at 1°C per minute between 20°C and 30°C, and heat treatment was carried out at the same time, so that the polyester The first substitution rea
