The antibacterial yarn is characterized in that the specification of the silver ion modified fiber is 1.33dtex multiplied by 35mm, the silver ion modified fiber comes from a silver ion modified fiber non-woven fabric which is prepared by compounding silver ions and polyester spunlace non-woven fabric by adopting a magnetron sputtering technology, the width of the non-woven fabric is 1000 +/-10 mm, and the quantification under the official moisture regain is 44 +/-4 g/m.
The spinning method of the antibacterial yarn is characterized by comprising the following operation steps:
(1) the modal fiber and the bamboo fiber are respectively processed into coils through a disc plucker, a multi-bin cotton mixer, a carding needle cotton opener, a vibrating cotton box cotton feeder and a single beater scutcher in sequence;
