Definitions

• the invention refers to a colouring treatment for clothing pieces in wool and mixed whool which, as as principle, carries out a mantle with changing sight perception that is determinated by a brilliant emerging part on an opaque colouring ground.
• the said colouring effect carries out a new conception mantle characterized by continuous tonal changes in accordance with the different observation angle, which is due to the depth colouring effect and by the hue of the emerging part from which the dye has been removed.
• the said depth colouring effect causes on the surface a down perception with brillianted whiteness and changing intensity according to the observation angle of the part.
• the treatment enables a sight perception of a soft mantle with close out hair given by the emerging part which gets varying brilliant tones on the colouring botton.
• Essential characteristic feature of the treatment in a preliminar way, consists in carrying out the dyeing operation of the dressing piece without fixing it in order to then cause the pigmentation spray on the mantel bottom, whereas the surface part takes again the original dye and, in particular, a dyeing tending to the neutral one.
• the material is laid in the dyeing tank with depurated water and glue, and with addition of pigment diluted with dispersing product.
• the bath is cooled down, the dyed material is rinsed and put again into clean water with addition of elastomerewhich acts as a dyeing binder.
• elastomere acts as a dyeing binder.
• Some catalizator is then added for fixing, then the piece is rinsed and centrifugated.
• the material is dried and rinsed with addition af softener.
• the tratmsnt causes the sedimentation of the very fine pigment dust on the bottom of the piece mantle bottom, carrying out a depth opaque colouring.
• a first operation phase performs dyeing without fixing the piece, which is at first dry-washed and then put in ⁇ to the dyeing tank with depurated water at the rate of 1 to 40 (40 litres of water and 1 Kg. of material), by adding a 10% of a gluey product, by acting with a rotating unit which turns during 30' at a temperature of 50°C.
• the dye is then added which consists of a pigment diluted with a dispersing product, and the machine turns during other 60' at 95°C. temperature.
• the dyeing bath is cooled down to 50"C, and the dyed material is rinsed.
• the treatment can be carried out on finished pieces, on working ones, as well as on material at the origin.
