Fabric with antibacterial effect and dyeing and finishing method of fabric

The invention discloses a fabric with an antibacterial effect and a dyeing and finishing method of the fabric. According to the functional fabric, 110 or more wool yarns and 65D or lower superfine denier curcuma longa viscose yarns serve as raw materials, the tightness in the warp direction is 75% or above, the tightness in the weft direction is 35% or above, at least one piece of warp backed weave exits in each fabric weave circulation, and the fabric is finally formed through a procedure. Besides the fact that the antibacterial raw materials are used, the twists of the yarns used on the surface weave and the liner weave of the fabric are different, and thus an inner-loose and outer-tight structure is formed so that harmful bacteria and the like can fall into the fabric when entering the fabric without direct contact with the skin; thus, dust, harmful bacteria and the like can be effectively blocked and prevented from entering, the antibacterial effect is achieved, the fabric is smooth in hand touch, and clothes made of the fabric are comfortable to wear; no chemical assistant is added for functional finishing, while the antibacterial effect can be achieved simply by changing selected raw materials and the fabric structure, so that the antibacterial effect is good, the antibacterial time is long, cost is low, the procedure is simple, and meanwhile damage to the human body and the environment is reduced.
