摘要:
The invention consists of a process to improve the resistance to stains on fibres, processed or not, finished or not on the basis of dyeable natural or synthetic fibres, in particular polyamide. According to the invention the fibres are treated with a solution containing tannic acid and a condensation product of a sulphonated phenol- or naphtol-derivate with an aldehyde. The treatment can be made before, during or after the dyeing process. The treatment is done in an acid medium.

The invention consists of a process to improve the resistance to stains on yarns, on the basis of wool, silk, polyamide, polyacrylonitrile, natural and artificial cellulosic fibres and in general, all other synthetical fibres which can be dyed. According to the invention the yarns are treated during the dyeing process with an aqueous solution containing up to 5 % tannic acid in acid medium. It is economically advisable to add a stabiliser to the solution to avoid oxidation of the solution and the fibres, and possibly a wetting agent. Preferably the treatment is made during the dyeing procedure, before, during or after the effective dyeing step.

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.
