A shaving aid for razor cartridges comprising water soluble filaments having nano-sized diameters and exhibiting lubricating properties and with improved visual and tactile aesthetics.

A fabric belt on which, when used as intended in a machine for producing spunbonded fabric webs, such spunbonded fabric webs are formed and transported. The belt has longitudinal threads and transverse threads that bind with the longitudinal threads. The threads are formed substantially of a polymer material and some of the longitudinal and/or transverse threads include electrically conductive material. The longitudinal threads form, on the web material contact side, convex longitudinal thread offsets with a knuckle, and the transverse threads have first transverse threads which form, on the web material contact side, first transverse thread offsets with a knuckle. A height difference between the knuckle crowns of at least some of the convex longitudinal thread offsets and the knuckle crowns of at least some of the first convex transverse thread offsets on the web material contact side is less than 220 μm or even less than 150 μm.

An apparatus for making nonwoven has a mesh belt moving in a horizontal direction and upstream and downstream spinnerets spaced apart in the direction above the belt and having downwardly opening tips at respective vertical spacings above the belt and each emitting fibers that are deposited at locations on the belt directly below the spinnerets to form thereon respective nonwoven layers. A support carrying the belt can be moved vertically and pivoted to orient the belt into a position forming an acute angle with respect to horizontal and thereby vary the spacings.

The invention relates to a respirator mask comprising a filter material piece made of an air-permeable material and at least one securing band, wherein the air-permeable material comprises at least one layer of a non-woven fabric and the at least one securing band is designed to secure the respirator mask to the head, wherein the air-permeable material and the at least one securing band are made of the same plastic material.

Provided are bicomponent fibers with improved curvature. The bicomponent fibers comprise a first polymer region or first region and a second polymer region or second region. The first region according to embodiments of the present disclosure comprises an ethylene/alpha-olefin interpolymer and has a light scattering cumulative detector fraction (CDF.sub.LS) of greater than 0.1200, wherein the CDF.sub.LS is computed by measuring the area fraction of a low angle laser light scattering (LALLS) detector chromatogram greater than, or equal to, 1,000,000 g/mol molecular weight using Gel Permeation Chromatography (GPC). The second region comprises a polyester. The bicomponent fibers can be used for forming nonwovens.

The present invention relates to filtration media made from melt-blown fibers having improved barrier properties. The melt-blown fibers in the filtration media of the invention are made of a visbroken metallocene-catalyzed propylene homopolymer composition with specified melting temperature Tm and molecular weight distribution (MWD).
