Definitions

• This invention relates to a process for the simultaneous release and dyeing of synthetic fibers and their mixtures, in general, and, more specifically, in polyester fibers and their mixtures with viscose and in polyamide fibers, and their mixtures with fibers. elastomers
• the invention is based on the development and application of a new surfactant, detergent / humectant, with a dispersing effect much greater than those currently known and used.
• the decoupling is carried out in strongly alkaline media at 80-100 ° C.
• acid type dyes are used, in the presence of binding agents and at temperatures between 100 and
• the decoupling is carried out in a reducing acid medium, using a non-ionic detergent medium. As for its tincture, it is usually boiled in order to increase the permeability to the dyes, maintaining the acidity of the medium.
• soluble cellulose esters are used in viscose fibers
• acrylic esters and polyester resins are used in polyesters
• polyacrylic acids are used in polyamides.
• two large groups of dyes can be distinguished, water soluble and insoluble dyes, using process technologies in discontinuous or continuous treatment, in machines at atmospheric pressure or under pressure at temperatures above 100 ° C.
• the high temperature dyeing is usually carried out in an autoclave, operating by bath circulation.
• the discontinuous wet treatment is carried out by continuously circulating the textile genre in the form of a rope through nozzle or jet staining facilities.
• the procedure, described in this Report and whose protection is requested refers to a system for the simultaneous decoupling and dyeing of synthetic fibers and their mixtures.
• Said agent is constituted on the basis of an alcohol with 8 to 14 carbon atoms with 2 to 10 moles of ethylene oxide plus 1 to 7 moles of propylene oxide, mixed with an alcohol between 7 and 15 carbon atoms oxyethylene with 1 to 8 moles of ethylene oxide and subsequently phosphated and / or phosphorylated.
• the process time is reduced by more than 1 hour, since the previous decryption used in the conventional process, requires an estimated time of 1 hour 50 minutes, as well as an estimated water saving of 30 1 / g. gender, since in the process according to this invention the water used is the same as that of the dyeing process.
