Embodiment 1
[0080] Continuous Yarn Pretreatment
[0081] The used yarn is 25.0tex pure cotton yarn, and the number of yarns can be 1-15. In this embodiment, one yarn is selected for pretreatment. Take 15 parts by mass of sodium hydroxide, 3 parts by mass of high-efficiency scouring agent OS-603, 3 parts by mass of alkali-resistant penetrating agent DS-100, and 78 parts by mass of water, stir evenly at room temperature, and prepare lye. Take 10 parts by mass of H2O2 and 90 parts by mass of water, stir evenly at room temperature, and prepare an oxygen solution.
[0082] Take the above-mentioned lye and oxygen solution, and evenly deliver the lye and oxygen solution to the yarn in the multi-pass dyeing and finishing device 6 through a propulsion pump, a syringe, and a catheter, and adjust the speed to 0.4-20m / min, wherein The lye supply rate is 0.01g-1g / min, the oxygen solution supply rate is 0.01g-1g / min, the vehicle speed is preferably 1m / min in the present embodiment, the lye supply rate...
Embodiment 2
[0085] Reactive Dyeing of Cotton Yarn without Salt
[0086] The yarn used is 21 counts of pure cotton yarn, and the number of yarns used can be 1-15. In this embodiment, 3 single yarns are selected for salt-free dyeing. Take 3 parts by mass of reactive violet X-2R, 97 parts by mass of water, stir evenly at room temperature, and prepare a dye solution.
[0087] Take 25 parts by mass of soda ash and 75 parts by mass of water, stir evenly at room temperature, and prepare soda lye.
[0088] Yarn: Through the push pump 7, the syringe 8, and the catheter 13, the above-mentioned dye solution is evenly delivered to the yarn in the multi-pass dyeing and finishing device 6, wherein the yarn running speed is 2m / min, and the dye solution supply speed It is 0.126g / min. When the yarn passes through the multi-pass dyeing and finishing device 6, it absorbs the dye liquor and runs upwards into the heating device 14 for heating and dyeing. The temperature is 130°C. A very small part of the dy...
