FIELD: textile industry.
SUBSTANCE: invention relates to a raised sheet material. The sheet material contains a non-woven material consisting of an ultra-thin fiber having an average diameter of elementary fiber of 0.3-7 mcm, and an elastic resin. The elastic resin is a polyurethane resin (D) that contains copolymerized polycarbonate diol (A1), which contains a structural block derived from alkane diol C3-5 (a1), and a structural block derived from alkane diol C8-12 (a2), wherein the molar ratio of alkane diol (a2) to the total number of moles of alkane diol (a1) and alkane diol (a2) is 50-95 mol.%; polycarbonate diol (A2), containing a structural block derived from alkane diol C4-6 (a3); organic diisocyanate (B); and a chain extension (C).
EFFECT: invention provides a sheet material that has a soft texture, has durability and the possibility to withstand practical use, as well as resistance to abrasion.
