Thermally stable absorbable fiber populations, i.e. fiber populations that do not undergo thermally induced crystallization, can be intermixed with thermally unstable fibers to yield a stabilizing effect without altering morphological properties of a fiber system. Via this, one may minimize thermally induced shrinkage and maintain physical properties of electrospun materials in the as-formed state.

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.

The invention relates to a compression bandage comprising a nonwoven-based bandage layer that has been stitched over with elastic textile threads by stitch bonding methods, the textile threads being heat-shrinkable and not elastomeric and the compression bandage having an elasticity after heat shrinking of the textile threads by 50-200%, particularly 50% to 90% and especially 50% to 70%. The invention also relates to a compression bandage combination.

Patterned fibrous substrates having a plurality of individual fibers, a first region, and a second region are provided. The patterned fibrous substrates have a plurality of individual fibers of the first region having a first diameter and a plurality of individual fibers of the second region have a second diameter, wherein the first diameter is less than the second diameter. The individual fibers of the first region and the individual fibers of the second region are substantially free of bonds, other than primary bonds. The first region has a first C.I.E. L* score, and the second region has a second C.I.E. L* score, according to the Color Test Method. The first C.I.E. L* score is different than the second C.I.E. L* score.

A nonwoven fabric having polylactic acid-containing fibers forming a nonwoven web is provided. The web has a side having an alternating pattern of individualized bonded areas which bonded areas define rods arranged in the cross direction of the web. The rods are arranged so that in the machine direction of the web no uninterrupted regions exist along the web while in the cross direction the arrangement of rods defines uninterrupted regions that extend continuously along the web, the alternating pattern of individualized bonded areas defines a non-bonded area. The web has a basis weight from 5-50 g/m.sup.2, the surface of the bonded areas is from 5-20% of the total surface of the side, and the surface of the non-bonded area is from 80-95% of the total surface of the side. Processes for forming the nonwoven fabric and an absorbent article including the nonwoven fabric are also provided.

A method for producing a sheet having nanofibers that contain a piezoelectric polymer material. The method including dissolving a piezoelectric polymer material into a solvent so as to prepare a spinning solution; preheating a target board before nanofibers are formed by electrospinning the spinning solution; and, after the heating of the target board, receiving the nanofibers formed by electrospinning onto the heated target board so as to form the nanofibers into a sheet on the heated target board.
