Nonwoven fabrics are provided that include a first nonwoven layer comprising a first plurality of fine fibers. The first plurality of fine fibers comprises a first polymeric material including (i) a first polymer component and (ii) optionally one or more first additives, wherein the first polymer component comprises a first recycled-polypropylene (rPP) comprising a visbroken spunbond grade polypropylene having a first melt flow rate (MFR) before visbreaking and second MFR after visbreaking, and wherein the second MFR is larger than the first MFR.

Method for producing a nonwoven fabric from fibres. Continuous filaments are produced from thermoplastic material by at least one meltblown spinneret. Chopped pulp fibres are also produced by at least one pulping device. In the pulping device, at least one chopped-fibre/air stream is produced from the chopped pulp fibres, is passed through and discharged from an outlet channel and flows with an initial volumetric flow V1 and a flow direction S1 in the direction of an air-permeable depositing screen belt. The continuous filaments flow from the at least one meltblown spinneret as a filament/air stream with an initial volumetric flow V2 in the direction of the chopped-fibre/air stream. The filament/air stream and the chopped-fibre/air stream are brought together above the depositing screen belt in a contact zone and deposited as a mixture of continuous filaments and chopped fibres in a depositing region on the depositing screen belt to form the nonwoven fabric or nonwoven web. In the depositing region of the fibres or of the mixture of continuous filaments and chopped fibres, air or process air is sucked through the depositing screen belt from below with a volumetric flow V4. The volumetric flow V4 is greater than the sum of the volumetric flows V1 and V2.

A nonwoven fabric having fibers composed of a polymeric blend of a polymer and a high loft additive. The nonwoven fabric exhibits increases in thickness, sound absorbance, and thermal resistance in comparison to a similar nonwoven fabric not having the high loft additive.

A method for manufacturing a melt-spun nonwoven fabric, in which fibers obtained by melt-spinning a thermoplastic polymer through a spinning nozzle having at least one or more nozzle holes are collected by high-speed air stream according to a spunbond method, includes: the steps of: allowing the melt-spun fibers to pass through local nozzle heaters of a nozzle heating mantle located just on the underside of the spinning nozzle during the spinning; and allowing the melt-spun fibers to be subjected to momentary local heating with a temperature difference of 0.1 to 1,000? C. from a temperature of a pack body. Polypropylene (PP) having a melt flow index (MFI) of 3 to 900 or polyethylene terephthalate (PET) having intrinsic viscosity (I.V.) of 0.5 to 3.0 is subjected to momentary local heating to a high temperature during the spinning to thus perform fiber fineness.
