Water intensity (wetting capacity) is an indicator characterized by the amount of moisture, g, absorbed by a sample of a material with an area of 1 m2 as a result of its immersion in water (has the dimension g / m2). It depends on the fibrous composition and porous structure of materials and varies widely: 1.46 ... 110 g / m2 for polyamide fabrics; 2.150 ... 300 g / m2 for cotton linen fabrics; 3,330 ... 770 g / m2 for woolen fabrics; 4. up to 1480 g / m2 for toweling; 5.To 2540 g / m2 for wool knitwear with
