The invention belongs to the technical field of antibacterial fabrics, and particularly relates to a high-breathability antibacterial fabric preparation device and process, the high-breathability antibacterial fabric preparation device comprises two side locking housings, a sliding groove is formed in the middle of the surface of one side of each side locking housing, rollers are slidably connected in the sliding grooves, one end of each roller is movably connected with a supporting cylindrical plate, and the other end of each roller is movably connected with a pressing plate; the two sides of the supporting barrel-shaped plate are fixedly provided with pressurizing plates, grooves are formed in the middle portions of the lower surfaces of the pressurizing plates, the roller coating in the padding pool can not only press and guide the fabric, but also stir the antibacterial agent in the padding pool under rotation, and when the roller coating presses the fabric, the antibacterial agent in the padding pool can be stirred, so that the antibacterial effect is improved. The antibacterial finishing agent and other coating materials can better permeate into fiber gaps of the fabric, the antibacterial agent is in full contact with the fibers under the compression effect, the adhesion rate of the antibacterial agent on the fabric is increased, it is like that tiny particles are squeezed into the gaps between the fibers, the particles are more firmly attached to the fabric, and therefore the durability of the finishing effect is improved.

This application relates to an antibacterial hydrocolloid dressing and its preparation method, belonging to the technical field of functional dressings. It comprises the following components in parts by weight: 60-65 parts hot melt adhesive, 5-10 parts polyisobutylene, 25-30 parts CMC, 0.8-1.2 parts CCMC, and 5.5-9 parts antibacterial component. The antibacterial component includes component A and component B. Component A includes at least one of sodium hydrogen phosphite, potassium dihydrogen phosphite, and sodium dihydrogen phosphate; component B includes at least one of zinc chloride and zinc nitrate. This application utilizes the in-situ generation of zinc-based phosphate antibacterial microcrystals during the preparation process of components A and B. It exerts its antibacterial effect through a multi-pathway synergistic mechanism of iron ion chelation to deprive nutrients and zinc ion disruption of cell membranes, effectively reducing the risk of bacterial resistance.
