FELT FROM SUPERABSORBING POLYMER AND METHOD OF MANUFACTURING THEREOF Russian patent published in 2015 - IPC D04H13/00 

FIELD: chemistry.

SUBSTANCE: subject of the invention is represented by a felt material, which contains, at least, one felt layer and one absorbent-containing layer, a method of the felt material manufacturing and the application of the felt material in textile products, footwear, for technical and medical purposes. The felt material in accordance with the invention possesses advantages of traditional felt materials with respect to heat- and sound-insulating properties and is air-permeable in the dry condition. However, due to special implementation the said material is waterproof in the wet condition and, therefore is suitable for sealing many types of materials. The felt material in accordance with the invention binds air moisture to a larger extent or binds water in a way, different from the traditional felt materials.

EFFECT: creation of the absorbent-containing material with high mechanical strength and good air permeability in the dry condition, in addition, the material must be suitable for air conditioning as, for instance, ventilation, dehydration and/or humidification of respective products made by means of it.
