FIELD: textiles, paper.
SUBSTANCE: invention relates to chemical technology of textile materials and relates to polymer thread and non-woven fabric. The polymer thread comprises a thermoplastic polymer and an inorganic filler, and the filler content, based on the polymer thread is more than 10 wt %, the average particle size of the filler is less than or equal to 6 mm, the weight of the surface unit is from 7 to 500 g/m2, the product of the weight of the surface unit and air permeability according to DIN EN ISO 9237 is in the range from 88000 to 132000, and the value of the coefficient of water column height according to DIN EN 20811 and the weight of the surface unit is within 2.5±0.5.
EFFECT: invention provides a polymer thread with high filler content, and nonwoven fabric obtained from it, having constant properties.
