A bathing cap has a body part substantially of a polyurethane foam material. The material includes a polyalcohol component, such as polyester polyol. Chain molecules of the material are cross-linked. Surface layers of the bathing cap have closed cells. The outer face surface is provided with structured formations formed as portions with a thickness other than the thickness of the remainder of the article. The body part of the cap has a thickness less than 1 mm. A method of manufacturing the bathing cap includes supplying components of the material and mixing the same so as to form a predetermined quantity of the polyurethane foam mixture, admitting said mixture into the deepest portion of a form member and inserting into the latter an insert member so as to form a space therebetween for forming the bathing cap and a gap for flowing out a surplus material, forming the bathing cap in the above space and subsequently separating the surplus material from the main part, that is from the bathing cap itself. The method may include heating of the above members, and adding a solvent substance to the components of the material so as to improve distribution of the material during forming the bathing cap.
A bathing cap, comprising an elastic body part composed substantially of a polyurethane foam material which includes a polyalcohol component consisting of polyester polyol, said body part having two spaced face surfaces defining a wall of said cap therebetween and two surface layers each adjacent a respective one of said face surfaces, said wall of said body part having a thickness which is substantially less than 1 mm, and said surface layers of said wall having closed cells.
