Abstract (en)
[origin: WO2022136218A1] An adhesive tape (1) which requires a smaller amount of adhesive by comparison with conventional adhesive tapes having the same adhesive properties is obtained using a method for producing an adhesive tape, which method comprises the following steps: a) mixing an ASE thickener with water and producing an (ASE) thickener–water mixture (7); b) producing an adhesive dispersion (8) from an adhesive and a solvent; c) providing a textile substrate (2); d) applying the (ASE) thickener–water mixture (7) to the textile substrate; e) applying the adhesive dispersion (8) to the (ASE) thickener–water mixture (7) in order to obtain the adhesive tape; f) drying the obtained adhesive tape; in which method the thickener, in particular the ASE thickener, is saturated with water and the adhesive dispersion (8) is applied after or at the same time as the (ASE) thickener–water mixture (7) is applied.
