Abstract
Inventia se refera la un procedeu pentru tratarea alcalina a materialelor textile celulozice din bumbac, in sau în amestec cu fibre chimice din celofibra, polinozice sau poliesterice, sub forma de tesaturi, tricoturi sau fire, constînd în impregnarea cu o solutie de hidroxid de sodiu, dezalcalinizare, neutralizare, spalare, caracterizat prin aceea ca impregnarea are loc la 60 degree C, concentratia de NaOH fiind de 200 g/l, materialul sub forma de banda parcurgînd în stare tensionata un pasaj în aer timp de 20 s, iar apoi fiind tratat 40 s la 20...30 degree C cu solutie NaOH de aceeasi concentratie, prin impregnari si stoarceri repetate, si la o instalatie pentru realizarea procedeului, constituita dintr-un fulard sau cada cu role pentru impregnare si stoarcere, si masina de mercerizat cu cilindri sau cu lant cu clupe.The invention relates to a process for the alkaline treatment of cotton cellulose textile materials in or in admixture with chemical fibers of celofibra, polyvinyl or polyester fibers in the form of fabrics, knits or yarns consisting of impregnating with a solution of sodium hydroxide, desalting, neutralization, washing, characterized in that the impregnation is carried out at 60 ° C, the concentration of NaOH being 200 g / l, the material in the form of a strip passing in a tensioned state a passage in air for 20 seconds and then being treated 40 s at 20 ... 30 ° C with NaOH solution of the same concentration, by repeated impregnations and squeezing, and at a plant for carrying out the process, consisting of a fulard or roller tube for impregnation and squeezing, and a mercerized car with cylinders or stubs.
