In still further aspects, the present disclosure pertains to a fabric, such as a denim fabric. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The invention relates to a spunbonded fabric of endless filaments made of thermoplastic plastic, wherein the endless filaments are designed as multi-component filaments having a core/sheath configuration. The filaments contain at least one lubricant, the lubricant being present exclusively or at least to 90 wt. % in the core component. The mass ratio between the core component and the sheath component is 65:35 to 80:20. The proportion of the lubricant is 250 to 5500 ppm with respect to the total filament.

A filter medium is provided. A filter medium according to an embodiment of the present invention comprises: a fiber web layer of a three-dimensional network structure including nanofiber; and a hydrophilic coating layer which covers at least a part of the outer surface of the nanofiber. According to this, a flow rate can be remarkably increased due to the improved hydrophilicity of the filter medium. Also, as the improved hydrophilicity is maintained for a long period of time, the lifespan can be remarkably prolonged. Furthermore, since the modification of a porous structure of the filter medium is minimized during the process of hydrophilization so that the initially designed physical properties of the filter medium can be exhibited in its entirety, the filter medium having chemical resistance, excellent water permeability and durability can be variously applied in the water treatment field.

A filter for a smoking article includes a filter component formed from a solution of cellulose acetate and a degradable polymer in aceton, the degradable polymer being soluble in acetone and degrading in the presence of water.
