The invention belongs to the field of
spinning, and discloses a process for controlling the generation of oil needle paths and creases of
polyester-mixed
cotton cloth, which comprises the following steps in sequence: gray cloth scutching, open-width oil removal, gray cloth rinsing, oil removal in a cylinder, and sleeve dispersion and
discharge from the cylinder. An oil removal agent used in open-width oil removal is a first oil removal agent; an oil removing agent used for removing oil in the cylinder is a second oil removing agent; the dosage of the first
degreasing agent is 1-2g / L; the use amount of the second
degreasing agent is 2.5 to 3.5 g / L; the open-width oil removal is implemented through a multi-stage oil removal process; the oil removal temperature is firstly increased and then reduced from front to back; the highest oil removal temperature is 80-90 DEG C; the first oil removal agent is prepared from the following components: PPG-4 C13-15
alcohol polyether-15, iso-tridecanol
polyoxyethylene ether, cocoanut
fatty acid diethanolamide,
triethanolamine oleate, an oil removal
penetration enhancer and water. According to the process, the double processes of open-width oil removal and in-cylinder oil removal are adopted, in the open-width oil removal process, primary oil removal is conducted through a high-temperature oil removal process, in-cylinder oil removal is conducted through use of a high-concentration oil removal agent, thorough oil removal is achieved, and through the operation,
oil can be thoroughly removed, and oil needle paths and creases are completely eradicated.
