Moisture absorption and sweat releasing cation polyester and manufacturing method thereof

The invention discloses a method for manufacturing moisture-absorbing and sweat-releasing cationic polyester, which comprises the following steps: putting cationic polyester into a dye vat, adding water into the dye vat according to a bath ratio of 1: (8-12), adding 8-10g/L of a mixture of an emulsifying dispersant and sodium hydroxide into the dye vat, then heating to 100-120 DEG C, keeping the temperature for 60-80 minutes, finally cooling to 40-60 DEG C, and keeping the temperature for 30-60 minutes, thereby obtaining the moisture-absorbing and sweat-releasing cationic polyester. Draining the dye vat; water is added into the dye vat according to the bath ratio of 1: (8-12), then glacial acetic acid is added, the temperature is increased to 100-120 DEG C, heat preservation is conducted for 60-80 min, and then liquid discharging is conducted on the dye Adding water into the dye vat according to a bath ratio of 1: (8-12), fully washing with water, and draining water from the dye vat; the preparation method co
