  • Publication number: 20240075704
    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.

  • Patent number: 11446916
    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.

  • Patent number: 10907038
    Abstract: Methods are provided for fabricating functional nanostructures (e.g., nanowires/nanofibers) via chemical vapor deposition polymerization of paracyclophanes or substituted paracyclophanes onto and through a structured fluid, such as a film of liquid crystals, on a substrate. A one-step process is provided that does not require the use of any solid templates, nor does it require any volatile solvents, additives or catalysts. The resulting nanowires/nanofibers can be in the form of aligned nanowires/nanofibers arrays supported on any solid material, in the form of nanofibers mats supported on porous materials, or as individual free-standing nanowires/nanofibers. By using chiral liquid crystals, chiral nanofibers can be fabricated. The functional nanowires/nanofibers can contain one or more type of surface reactive groups that allows for post surface chemical modifications on the nanowires/nanofibers. Such nanostructures can be used in a range of different applications, including in biomedical applications.

  • Publication number: 20200254720
    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.

  • Publication number: 20200255995
    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.

  • Patent number: 8939008
    Abstract: A method of calibrating an articulating probe head comprising the steps of measuring an artifact of known dimensions with the workpiece sensing probe mounted on the articulating probe head, in which the articulating probe head is unlocked. An error functional map is generated corresponding to the difference between the measured and known dimensions of the artifact. Subsequent workpieces are measured with the articulating probe head unlocked and the corresponding correction applied. The true dimensions of the artifact may be determined by measuring it with a probe mounted on an articulating probe head in which the axes of the articulating probe head are locked. A mechanical lock is provided to lock the axes of the articulating probe head.
