A composite resin tank includes a wall joined to a dome along a joint. A softening strip is located in the joint.

A spunbond nonwoven laminate has a stack of at least two and at most four spunbond nonwoven layers each formed by or consisting of crimped continuous filaments. A degree of crimping of the filaments in each of the spunbond nonwoven layers is different from a degree of crimping in each of the other spunbond nonwoven layers and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments each having at least one first plastic component and at least one second plastic component with each of the plastic components being present in the respective filament in a proportion of at least 10 wt %.

Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.

A web modified according to the disclosed method has desirable breathability and liquid impermeability, as well as extensibility and a soft, cloth-like textured surface.

A three-dimensional netted structure having an upper surface, a lower surface, two side surfaces a left end surface, and a right end surface, including at least a plurality of filaments helically and randomly entangled and thermally bonded together, wherein the filaments are formed out of a thermoplastic resin by extrusion molding followed by cooling with a liquid; and the netted structure is four-surface molded, the upper surface, the lower surface and the two side surfaces being molded. An apparatus and a method for manufacturing the three-dimensional netted structure.

A method is disclosed for modifying the physical characteristics of a web which involves passing the web between at least one pair of interengaged rolls to incrementally stretch the web, and then withdrawing the incrementally stretched web from between the rolls under tension. A web modified according to the disclosed method has desirable breathability and liquid impermeability, as well as extensibility and a soft, cloth-like textured surface.

A hygiene article including a nonwoven web having nanofibers. The hygiene articles include diapers, training pants, adult incontinence pads, catamenials products, tampons, personal cleansing articles, and personal care articles. The nanofiber webs can be used as a barrier, wipe, or absorbent material. Particularly, the nanofiber web is used in a diaper as a barrier-on-core, outercover, and/or leg cuff. It may also be used as a wipe.

The present invention provides compositions comprising aligned fibers of electrospun PNIPAAm and poly (-caprolactone) (PCL) (denoted PNIPAAm/PCL fibers). The PNIPAAm/PCL compositions enable enhanced growth and detachment of intact anisotropic cell sheets. The compositions do not require chemical modification or resource-intensive techniques, thus saving time and expense, and have the potential to generate tissue-specific, aligned cell sheets for transplant studies.
