Embodiment 1
[0026] Embodiment 1: This embodiment provides a kind of cheese dyeing method for cationic modified cotton yarn, comprises the following steps:
[0027] Step 1, use a winder to loosely wind the cationic modified cotton yarn to obtain cheese yarn; the cationic modified cotton yarn used in this embodiment is 40 inches, and the yarn used is 213kg; SSM winder, Savi Austrian winding machine or Haishihua winding machine, the winding speed is 700-900r / min; the package weight is 1.0kg / piece, and the density is 0.32-0.38g / cm 3 ;
[0028] Step 2, Dyeing:
[0029] The package yarn that step 1 obtains is put into dye vat, carries out water injection to dye vat for the first time; If package yarn gross weight is M kilogram, then the water injection volume is 8M-15M liter; The present embodiment presses 8.7M liter water injection;
[0030] Warm up the water to 30-40°C (preferably to 30°C), add reactive dyes to the water according to the curve feeding method, wherein the curve feeding time ...
