Voluminous non-woven composite produced from a first tier of randomly deposited melt-spun continuous filaments and from a second tier of crimped staple fibres, characterized in that a) the continuous filaments have a linear density of 0.8 to 1.8 dtex, preferably of ≤ 1.3 dtex, particularly preferably of 1.0 to 1.2 dtex; b) the crimped staple fibres have a linear density of 2.2 to 15 dtex, preferably of 4 to 10 dtex; c) the tiers for configuring the voluminous non-woven composite are exclusively hydroentangled and are inherently connected to one another in such a manner that the original multi-tier structure is lost; wherein the non-woven composite has pores having a diameter of 0.2 mm to 0.4 mm; wherein the measuring of the pore size by means of a sieve testing apparatus AA200 by the Retsch company is carried out as follows: • the non-woven composite is clamped in, or placed onto, a sieve, respectively; • 5 g of glass spheres of a predefined diameter are placed onto the clamped non-woven composite; • the non-woven composite is made to vibrate at a vibration amplitude of 2 mm for a duration of 3 min; • it is subsequently checked whether glass spheres have travelled through the non-woven composite, wherein the non-woven composite has pores of a pore size which correspond to at least the diameter of the glass spheres when a quantity of at least 1.5% by weight passes through the non-woven composite, wherein the largest pore is indicated by the largest penetrating glass sphere. a) the continuous filaments have a linear density of 0.8 to 1.8 dtex, preferably of ≤ 1.3 dtex, particularly preferably of 1.0 to 1.2 dtex; b) the crimped staple fibres have a linear density of 2.2 to 15 dtex, preferably of 4 to 10 dtex; c) the tiers for configuring the voluminous non-woven composite are exclusively hydroentangled and are inherently connected to one another in such a manner that the original multi-tier structure is lost; wherein the non-woven composite has pores having a diameter of 0.2 mm to 0.4 mm; wherein the measuring of the pore size by means of a sieve testing apparatus AA200 by the Retsch company is carried out as follows: • the non-woven composite is clamped in, or placed onto, a sieve, respectively; • 5 g of glass spheres of a predefined diameter are placed onto the clamped non-woven composite; • the non-woven composite is made to vibrate at a vibration amplitude of 2 mm for a duration of 3 min; • it is subsequently checked whether glass spheres have travelled through the non-woven composite, wherein the non-woven composite has pores of a pore size which correspond to at least the diameter of the glass spheres when a quantity of at least 1.5% by weight passes through the non-woven composite, wherein the largest pore is indicated by the largest penetrating glass sphere. • the non-woven composite is clamped in, or placed onto, a sieve, respectively; • 5 g of glass spheres of a predefined diameter are placed onto the clamped non-woven composite; • the non-woven composite is made to vibrate at a vibration amplitude of 2 mm for a duration of 3 min; • it is subsequently checked whether glass spheres have travelled through the non-woven composite, wherein the non-woven composite has pores of a pore size which correspond to at least the diameter of the glass spheres when a quantity of at least 1.5% by weight passes through the non-woven composite, wherein the largest pore is indicated by the largest penetrating glass sphere.
