Field of the Invention The present invention relates to a method of manufacturing a nonwoven fabric, and more particularly to a method of manufacturing a composite elastic nonwoven fabric having properties such as water repellency, moisture permeability and elasticity. ...[Previous Technology] * - Pressed, non-woven fabrics have been widely used in household goods, hygiene products and medical supplies, such as disposable diapers, sanitary napkins, surgical gowns, etc. Many people are exposed to non-woven products every day but they are unconscious. People's lives are huge. Generally, the non-woven fabric is mainly composed of several layers of different mesh layers, such as an air layer mesh layer (abbreviated as A), a spunbond layer (S), and a meltblown mesh layer (abbreviated as Μ). ), together form a composite non-woven fabric, or according to the characteristics of the composite non-woven fabric, select a functional raw material to make a special-purpose intermediate layer, and give the composite non-woven fabric functionality. If pulp or superabsorbent polymer is used as the raw material of β as the intermediate layer, the composite non-woven fabric can be imparted; if activated carbon fiber is used as the raw material of the intermediate layer, 'the chemical non-woven fabric can be imparted to the nonwoven fabric; pulp and hot melt The intermediate layer of the rubber powder will impart stiffness.
基於前述之複合式不織布特性，SMA不織布中，Α層使 用具吸收性的材料製造，而裡層的Μ層具有防水性，該SMA _不織布便可用作衛生棉材料。又，將具有防水性的Μ層置 於表層，而使用具吸收性的Α層作為裡層，則能夠使用於 手術用材料的製造。 雖然，藉由上述的製造方式，可以製造出具有不同特 性之複合式不織布製品，卻仍有加以改良的空間。譬如居Based on the aforementioned composite non-woven fabric characteristics, in the SMA non-woven fabric, the enamel layer is made of an absorbent material, and the inner layer of the enamel layer is water-repellent, and the SMA _ non-woven fabric can be used as a sanitary napkin material. Further, the water-repellent enamel layer is placed on the surface layer, and the absorbent enamel layer is used as the inner layer to be used for the production of surgical materials. Although the composite nonwoven fabric having different characteristics can be produced by the above-described manufacturing method, there is still room for improvement. Ruru
