Disclosed herein a stitch-bonded fabric comprising at least one fibrous web layer having a plurality of the fibers with a first length of more than about 25 mm, oriented substantially in a cross-direction (XD) of the stitch-bonded fabric wherein a density of the at least one fibrous web layer is less than about 0.12 g/cm.sup.3. The at least one fibrous web layer is stitch-bonded with yarns following a pattern of linear stitches along a machine direction (MD) spaced from about 1.4 mm to about 4.0 mm along XD, and repeating with a spacing front about 0.8 mm to about 2.5 mm in MD, wherein the plurality of fibers having said first length are captured by multiple stitches. A density of fibers and yarn enclosed within the stitches is above about 0.10 g/cm.sup.3 and below about 5.0 g/cm.sup.3 and the linear stiches are depressed below exposed the wales between the linear stitches along MD. The stitch-bonded yarns can be heat set to stabilize the stitch-bonded fabric.

The invention relates to a method for the production of a textile object having electrostatically charged fibres and to a textile object. A die arrangement comprising at least two separate dies or a multipolymer die is used for the production of fibres from different polymers, whereby the polymers are spaced sufficiently apart in a triboelectric series. During the process, the fibres produced from the polymers are co-mingled, at least in sections, and charged triboelectrically. Alternatively or in addition, the fibres are charged triboelectrically by means of an uncomplicated finishing process. Filters with quality factors greater than 0.2 can be produced with the textile object.

An apparatus for continuously making a spunbond web of filaments comprises a spinneret, a cooling chamber into which process air for can be introduced for the purpose of cooling the filaments, a monomer suction device between a spinneret and cooling chamber, a stretcher and a deposition device for depositing the filaments of the spunbond web. The cooling chamber is divided into two cooling compartments, and process air can be suctioned out from a first upper cooling compartment at a volumetric flow rate (V.sub.M) to a monomer suction device. Process air exits from the first upper cooling compartment at a volumetric flow rate (V.sub.1) into a second lower cooling compartment and from the first upper cooling compartment at a volumetric flow rate (V.sub.1) into a second lower cooling compartment. A ratio (V.sub.M/V.sub.1) is 0.1 to 0.35.
