Embodiment Construction
[0014] Embodiments of the present invention: a spinning process of a variety of fiber blended yarns, comprising the following steps:
[0015] (1) Cotton fiber modification: Add the reaction medium into the reaction vessel, add 3-chloro-2-hydroxypropyltrimethylammonium chloride, NaOH and the reaction medium into the reaction vessel under stirring conditions to form a reaction solution, and then the cotton fiber is added to the reaction solution to react, and the cotton fiber is washed to neutrality after treatment to obtain a high cationic cotton fiber;
[0016] (2) Selection of spinning raw materials: 15%-25% high cationic cotton fiber, 20%-30% ramie and 50%-60% viscose fiber are selected as blended yarn raw materials;
[0017] (3) Blowing and carding: After mixing high cationic cotton fiber, ramie fiber and viscose fiber, clean it on the cleaning machine. The noil distance of the cleaning machine is 1.5-2mm. The raw sliver is obtained by carding, the gauge between the cardin...
