摘要： A nonwoven sheet contains a substrate layer formed from a fiber aggregate nonwoven structural member; the fiber aggregate nonwoven structural member containing a thermal adhesive fiber; the thermal adhesive fibers are melt-bonded to fix the fibers of the member. The average thickness of the substrate layer is adjusted to not less than 0.2 mm to less than 1 mm, and the thermal adhesive fibers are substantially uniformly melt-bonded in a surface direction of the substrate layer. The sheet may have a surface layer over at least one side of the substrate layer, the surface layer may contain a fiber aggregate nonwoven structural member having an apparent density higher than the apparent density of the substrate layer. The surface layer may comprise a layer formed by heat-pressing or may be formed from a meltblown nonwoven fabric. The thermal adhesive fiber may be substantially uniformly melt-bonded in a thickness direction of the substrate layer. The thermal adhesive fiber may contain an ethylene-vinyl alcohol-series copolymer; the copolymer may form a continuous area of a surface of the fiber. The sheet has an improved flexural rigidity, less deformation under a load, and an excellent formability, in spite of a small thickness thereof.

摘要： A cleaning pad structure of stitch bonded construction incorporating one or more substrate layers of an absorbent nonwoven material with an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers. Stitching yarns are introduced in stitching relation through the substrate layers. One face of the pad defines a cleaning surface of raised yarn loops formed by the stitched yarns. The pad further includes an attachment surface facing away from the cleaning surface. The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system.

摘要： Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. Antishrinkage and antistatic additives are also added to the fibrous webs. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

摘要： Disclosed are an artificial dura mater and manufacturing method thereof. The artificial dura mater includes electrospun layers prepared by electrostatic spinning, at least one of which is a hydrophobic electrospun layer. Further, above the hydrophobic electrospun layer, there can be at least one hydrophilic electrospun layer. A transition layer can be further included between the hydrophobic and the hydrophilic electrospun layers. Additionally, cytokines and/or medicines can be affixed to either or both of the hydrophobic and the hydrophilic electrospun layers, by way of bio-printing. The disclosed artificial dura mater shows good biocompatibility, enhances dural tissue regeneration, achieves excellent repairing effects, prevents adhesion, allows complete absorption, has good mechanical properties, ensures low infection rates, and can be loaded with therapeutic agents.
