Abstract: A cleaning device connectable to a handle includes a head (100) with a substantially circular profile formed by a plurality (200) of flexible strips in non-woven fabric overlapped and arranged to cover the circumference of the head (100) wherein the outermost strips (1) of the plurality of overlapped strips (200) have the outer surface formed by a microfiber layer (8) supported by a non-woven fabric layer (9), and the innermost strips (3) have a greater stiffness than the remaining strips.

Abstract: There is described the use as textile material to produce cleaning devices of a “double-layer” non-woven fabric having a microfiber layer supported by a macrofiber layer wherein the layers are bonded by needle-punching and subsequent treatment of the microfiber surface with high pressure water jets.

Abstract: A feed supplement for arthropods, in particular for lepidopteran larvae, comprising a low alkyl ester of a biologically active acid or alpha-amino acid. Said alkyl esters of a biologically active acid or alpha-amino acid have general formula (I), in which: X is hydrogen or NH2; R1 is a straight or branched alkyl or alkenyl group, containing 3 to 6 carbon atoms, optionally substituted with at least one hydroxy, carboxylic, amino, amido, guanidyl, thio, methylthio, phenyl or imidazolyl group; and R2 is a group selected from methyl, ethyl and propyl.
