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 system having a first polymer source and a spin beam in fluid communication with the first polymer source is provided. The spin beam includes a spinneret assembly having filament nozzles configured and arranged to extrude a plurality of filaments of a first polymer. A gas distribution plate is disposed downstream of the spinneret assembly, and includes a plurality of gas distribution slots that are configured and arranged to receive two or more corresponding filament nozzles of the spinneret assembly therein. A stream of gas is introduced into the plurality of slots to draw and attenuate the filaments extruded by the plurality of filament nozzles. The drawn and attenuated filaments are collected on a collection surface disposed downstream of the gas distribution plate to form a nonwoven fabric. A solid additive, such as pulp fibers may be blended with the filaments prior to collecting the filaments on the collection surface.

摘要： Method and apparatus for manufacturing span bond nonwoven fabrics formed from continuous fibers which are small in fineness and high in strength and manufactured by the steps of spinning for obtaining a continuously drawn fiber by blowing a molten resin extruded out of a spinning nozzle by heated gases blown out of the periphery of the spinning nozzle; drawing for further drawing the obtained continuously drawn fiber by an air stream produced due to a pressure difference of gases; the extreme end of the nozzle being a distance of 0.5 to 2 m from the place where further drawing occurs; collecting for collection the drawn continuous fiber to collect the fibers; and uniting for uniting the collected continuous fibers together to form nonwoven fabrics.

摘要： A process apparatus for producing a non-woven, especially a non-woven electret, fiber sheet provides for directing the non-woven fibers at a collecting surface and into an electric field between at least one electrode and the collecting surface.This process, in which the fibers are collected in the electric field, enables the economical production of a non-woven electret fiber sheet of single layer structure having large amount of polarized charges (giving a total electric charge per unit area of at least 7.times.10.sup.-11 Coulomb/cm.sup.2), and a weight of at least 60 g/m.sup.2, preferably greater than 80 g/cm.sup.2.The non-woven electret sheet may have the large amount of electret charge throughout its thickness and/or a uniform weight distribution and thus have excellent dust collecting properties.
