发明名称 METHOD FOR SEPARATING A TEXTILE PRODUCT CONSISTING OF AT LEAST TWO CONSTITUENTS
摘要 The invention relates to the creation of a continuous, cost-effective and ecological method, in the embroidery industry, for separating a cellulosed constituent of a carrier layer from single-element or multi-element constituents of a textile wear layer, with low retention time and minimal stress on the wear layer. In order to achieve this, the textile product consisting of at least two constituents is treated over a plurality of stages with aqueous amino oxides, preferably N-methylmorpholine-N-oxide (NMMO), until the carrier constituents consisting of polysaccharides, preferably cellulose, are fully separated from the wear layer by means of dissolution. The cellulosed constituents can partially contain starch and/or starch derivatives. Amine oxide adhering to the wear layer is removed by washing with water. Scouring baths are used for the precipitation of the dissolved cellulose. The precipitated cellulose is separated from the amine oxide, is used for another purpose, or is disposed of, by means of filtration, centrifuging or similar processes.
