Abstract: Provided are an elastic composite non-woven fabric and a manufacturing equipment and a manufacturing method thereof, wherein the elastic composite non-woven fabric manufacturing equipment includes an upper feed roller, an upper shrink roller, an upper bonding roller, upper fins, an middle feed roller, an winding roller, a lower feed roller, a lower shrink roller, a lower bonding roller, and lower fins. Wherein, two elastic non-woven fabrics shrink inward by the shrink roller and enter the gaps among the fins and grooves and teeth of the bonding roller to form regular wavy folds; the two pre-shrunk elastic non-woven fabrics are bonded to the upper and lower surfaces of the elastic material in a flat state by the aligned and adjacently disposed teeth of the bonding roller, thereby forming an elastic composite non-woven fabric.

Abstract: A method to manufacture an elastic laminate is disclosed. Thermoplastic Elastomeric Material (TEM) is selected from a polymer supply and fed into an extruder. The TEM film is extruded by the extruder by passing the TEM polymer through an extrusion die head to form a TEM film layer on a carrier web provided by a carrier supply. The TEM film layer is allowed to solidify on the carrier web, thereby forming a first laminate. The first laminate is stored in a first storage prior to being delivered to a delamination unit, which delaminates the first laminate by separating the TEM layer from the carrier web. The delaminated TEM layer is stretched at least in its Machine Direction (MD) in a stretching station via a plurality of web guide means. The stretched TEM layer is positioned between a first envelope web and optionally a second envelope web prior to being delivered to a bonding unit, which connects them to form a second bonded laminate.

Abstract: The present invention relates to a multi-layered elastic air-permeable material structure, including an elastic cloth and an elastic film, wherein the elastic cloth is constituted of polylactic acid, has a plurality of penetrating air vents, and has a weft-direction stretchability. The elastic film is constituted of a thermoplastic elastomer material, and it also has a plurality of penetrating air vents. An upper surface of the elastic film is entirely or partially adhered to a lower surface of the elastic cloth. In particular, the elastic film has an air permeability of 17-25 cc/sec per square centimeter, and the multi-layered elastic air-permeable material structure has an air permeability of 7-10 cc/sec per square centimeter. The present invention has the advantages of weft-direction stretchability and air permeability and is suitable for applying to close-fitting clothing or diapers to improve comfort and prevent sultriness and moisture.

Abstract: An elastic non-woven fabric with bicomponent elastic composite fibers, manufactured by randomly paving bicomponent elastic composite fibers as a layer and hot-rolling. The bicomponent elastic composite fiber includes an inner core fiber of SBS, SEBS, TPO or TPS and a sheath outer layer of PP or PE covering on an outer surface of the inner core fiber. A ratio of a thickness of the sheath outer layer to a radius of the inner core fiber is 1:9 to 9:1. The bicomponent elastic composite fiber has a linear density of 0.5-5 deniers, a stretchability of 300-600%, and a deformation rate of 0-25% after being stretched to 400%. The present invention has the advantages of good elasticity, good stretchability, good dyeability, acid and alkali resistance, quick-drying and non-absorbency, antibacterial and deodorizing, and light and soft texture properties, thereby can avoid cold and sticky feel and will not cause reflection.

Abstract: An elastic non-woven fabric, manufactured by bonding a pre-stretched elastic film and elastic cloths, includes an elastic film with a stretch range of 0-300% and two elastic cloths each with a stretchability of 150-300%. While at the second natural width, the two elastic cloths are respectively bonded to upper and lower surfaces of the elastic film pre-stretched to a first stretched width. By bonding the two elastic cloths to the elastic film after stretching the elastic film in advance, the elastic non-woven fabric of the present invention can have high stretchability and high tensile strength and thus will not have serious wrinkles on the surfaces thereof and will not be easily torn broken. Because the stretchability of the elastic non-woven fabric is greatly improved, the user can use a smaller cutting width to divide each cylindrical master-roll into more cylindrical sub-rolls, thereby improving the production efficiency.

Abstract: A bicomponent elastic fiber composite material, which has a linear density of 20-150 deniers, a stretchability of 300-600%, and a deformation rate of 0-25% after stretching to 400%. The bicomponent elastic fiber composite material includes an inner core fiber and a sheath outer layer, wherein the inner core fiber includes a polystyrne copolymer material of a styrene-butadiene block copolymer (SBS), a styrene-ethylene-butylene-styrene block copolymer (SEBS) or a thermoplastic polyolefin elastomer (TPO), or includes a thermoplastic polystyrene elastomer (TPS). The sheath outer layer includes polypropylene (PP) or polyethylene (PE). Thereby, the present invention can realize zero pollution while recycled and reused. In addition, the present invention has excellent properties of elasticity, dyeability, acid and alkali resistance, quick-drying and non-absorbency, antibacterial and deodorizing, and has a soft texture.

Abstract: A method for manufacturing an elastic composite fabric, includes a combining step, where an elastic outer layer is disposed onto a top side of an elastic nonwoven fabric which has characteristics to prevent penetration of a filling material, a fiber density of 0.8 to 5.0 denier and a weight of 8 to 100 g/sqm (±40%), and a first cloth body is disposed onto a bottom side of the nonwoven fabric, wherein the first cloth body is an elastic outer layer or elastic nonwoven fabric with a fiber density of 0.8 to 5.0 denier and a weight of 8 to 100 g/sqm (±40%); and a filling step: filling the filling material within several filling spaces between the elastic outer layer and the elastic nonwoven fabric or within several filling spaces between the elastic nonwoven fabric and the first cloth body in order to obtain the elastic composite fabric.
