PROCESS AND DEVICE FOR SPLITTING A TAPE
20190062949 · 2019-02-28 · ·

A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a splitting profile having a row of parallel teeth with a cutting edge extending in the process direction. The tape is split to form a tape comprising a plurality of parallel strips interconnected by fibrils. The split tape can for example be used for the production of high tensile ropes.

Hygiene articles containing nanofibers

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.

Textile made from chains and process for its manufacture
10190853 · 2019-01-29 ·

A system and method is described for easily creating textiles out of chains connected by thread. A dissolvable or removable substrate on which chains can be set is used whereby the thread stitching passes through the substrate. After the textile stitching is completed, the substrate is then removed, including by use of a dissolving solvent or by melting.

10112740 · 2018-10-30 · ·

The present invention is directed to tamper-evident mesh material, methods of manufacture therefor, and tamper-evident bags manufactured therefrom. The tamper-evident mesh material of the present invention may be used, for example, in the manufacture of a variety of tamper-evident security bags for use in applications where it is desirable to detect any traces or evidence of tampering with or of unauthorized access to the contents of the bag.

Method for making a composite material

A hydroformed expanded spun bonded nonwoven has a first substantially planar surface on one side thereof and a second surface on an opposite side thereof. The second surface includes a plurality of protuberances in a pattern. The hydroformed expanded spun bonded nonwoven web has an average loft of at least about 1.3 times greater than an original average loft of an original unexpanded spun bonded nonwoven web from which the hydroformed expanded spun bonded nonwoven web was created and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web includes bicomponent fibers combining a polymer with PLA in a ratio of polymer/PLA within a range of about 20/80 to 80/20.

METHOD FOR MAKING A COMPOSITE MATERIAL

A method for manufacturing a composite material includes forming a composite precursor material comprising a nonwoven layer comprising a plurality of fibers and a polymer film layer laminated to the nonwoven layer; forming a plurality of apertured extended cells in the polymer film layer, each of the apertured extended cells having a continuous sidewall extending away from the nonwoven layer that terminates in an aperture at a distal end; and, while forming the plurality of apertured extended cells, pushing, with a fluid, at least one of the fibers into at least one of the apertured extended cells so that a portion of the at least one of the fibers extends into the at least one of the apertured extended cells and through the aperture at the distal end.
