Abstract

Inventia se refera la un procedeu de tratare alcalina a materialelor din fibre celulozice 100% si fibre celulozice în amestec cu fibre sintetice. Procedeul, conform inventiei, în scopul reducerii consumurilor energetice si cresterii productivitatii muncii, consta în aceea ca tesaturile crude sau pârlite - descleiate sau pârlite, descleiate si termofixate sunt impregnate cu o solutie alcalina continând 2...6% alcalii (raportate la greutatea uscata a materialului textil), 0,2...1% produse de udare-fierbere, pâna la 0,2% substante cu caracter reducator, eventual 1...3% emulsie de petrosin (sau alti solventi de curatire), stoarse pâna la un grad de stoarcere cuprins între 70 si 200% si supuse unui tratament termic la o temperatura între 60 si 100 degree C, o durata de 30 min si 60 min, sub actiunea unui câmp de microunde de putere 3,5...4 kw si o frecventa de 2450 KHz.The invention relates to a process for the alkaline treatment of materials from 100% cellulose fibers and cellulosic fibers in admixture with synthetic fibers. According to the invention, according to the invention, the process for reducing energy consumption and increasing labor productivity consists in the fact that the raw fabrics or loose, loose or topped, loose and thermofixed, impregnated with an alkaline solution containing 2 ... 6% alkali (based on dry weight of the textile material), 0.2 ... 1% water-boiling products, up to 0.2% reducing substances, possibly 1 ... 3% petrosine emulsion (or other cleaning solvents), squeezed at a squeeze rate of between 70 and 200% and subjected to a thermal treatment at a temperature between 60 and 100 degrees C, a duration of 30 minutes and 60 minutes under the action of a 3.5 ... kw and a frequency of 2450 KHz.
