[0011] Example 1: The vat dye dyeing method of polyester-cotton fiber cheese yarn of this example, the steps are:
[0012] The specification of polyester-cotton fiber yarn is 80S / 2, the number is 18 bobbins, and the dyeing color is khaki bobbins.
[0013] Yarn loosening: Firstly, the 80S / 2 polyester-cotton fiber yarn purchased from the market is loosened on the SSM DP1-W yarn loosening machine, and the polyester-cotton fiber yarn is loosened by digital winding. The density of the package is 0.36. g / m 3 , The weight of a single bobbin is 800g;
[0014] Pre-treatment: First, put the loosened yarn on the creel, place the creel in the dye vat, close the dye vat cover, call up the production program on the process card, and set the bath ratio to 1 :10, that is, 1kg of yarn needs to be equipped with 10kg of water, first inject 70% of the amount of water into the dyeing vat, add caustic soda to the attached vat at room temperature, add 2.5g / l, high-efficiency refining auxiliary 2.5g / l.
