The invention also relates to a process for the manufacture of the copolymers which are present in the copolymer solution; additionally, the invention relates to the use of the copolymer solution for the manufacture of coating compositions for lacquer systems of low solvent content which contain polyisocyanates and which contain the copolymer manufactured according to the invention as a resin component which carries hydroxyl groups.

Abstract: Non woven webs are produced from filaments by laying down the said filaments in the form of cone sections on a moving surface with simultaneous spreading out to a filament veil with the use of rotating deflectors coming into contact with the filaments on one side only. The deflecting area of the deflectors has a plane shape. The filaments used are drawn, partially drawn or undrawn. A non woven web with particularly good properties is obtained when the axis of the bundle of filaments and the deflecting surface of the deflector form an angle of from 10.degree. to 80.degree.. To produce the web a simple and reliable device is used.
