A nonwoven article includes a plurality of electrospun polycrystalline, aluminosilicate ceramic filaments that form a cohesive nonwoven mat. Each of the aluminosilicate ceramic filaments in the mat have an average diameter of about 200 nm to about 1000 nm as determined with electron microscopy, and the aluminosilicate ceramic filaments have an average crystalline mullite content of about 15 wt % to about 80 wt %.

The present disclosure provides for aqueous, curable binder compositions, as well as articles and products comprising assemblies of matter comprising mineral fibers, synthetic fibers, natural fibers, cellulosic particles and sheet materials comprising the binder compositions disclosed herein.

Embodiments described herein may take the form of a textile product having one or more regions of reduced density. These reduced density volumes may form one or more features in the product. For example, the reduced density volumes may have better acoustic transmission properties, optical transmission properties, flexibility, and the like. Sound transmission may be enhanced not only in terms of clarity, but also overall range. That is, certain audio frequencies that the textile may normally block when in an unaltered state may pass through a textile having reduced density or reduced density regions.

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.

Nonwoven multilayer structures having at least two nanofiber layers are described herein. The nonwoven multilayer structure may have two nanofibers layers that have different properties from each other, such as fiber diameter. One nanofiber layer may be produced by an electrospinning process, while another nanofiber layer may be produced by a melt blown process.
