摘要： A breathable and waterproof non-woven fabric is manufactured by a manufacturing method including the following steps. Performing a kneading process on 87 to 91 parts by weight of a polyester, 5 to 7 parts by weight of a water repellent, and 3 to 6 parts by weight of a flow promoter to form a mixture, in which the polyester has a melt index between 350 g/10 min and 1310 g/10 min at a temperature of 270° C., and the mixture has a melt index between 530 g/10 min and 1540 g/10 min at a temperature of 270° C. Performing a melt-blowing process on the mixture, such that the flow promoter is volatilized and a melt-blown fiber is formed, in which the melt-blown fiber has a fiber body and the water repellent disposed on the fiber body with a particle size (D90) between 350 nm and 450 nm.

摘要： A manufacturing method of a meltblown fiber membrane includes the following step. A meltblown film is made to pass between a first pressing roller and a second pressing roller, such that a calendering process is performed on the meltblown film, in which the meltblown film includes a plurality of meltblown fibers, each of the meltblown fibers includes a high-fluidity polyester and a modified polyester, a melt index of the high-fluidity polyester under a temperature of 230° C. ranges from 350 g/10 min to 550 g/10 min, a melt index of the modified polyester under a temperature of 230° C. ranges from 200 g/10 min to 400 g/10 min, and a roller temperature of each of the first pressing roller and the second pressing roller ranges from 100° C. to 155° C.
