Abstract
Inventia se refera la un procedeu de tratare alcalina, concomitent cu albirea tesaturilor din amestec de fibre celulozice cu poliesterice si consta în aceea ca în scopul reducerii consumului de energie termica si al cresterii productivitatii ,muncii, tesaturile crude sau pârlite, descleiate si temofixate, se impregneaza din ud cu o solutie ce contine 60...100 g/l soda caustica, 2...10 g/l soda calcinata, 2...10 g/l detergent de fierbere, 10...20 ml/l. Perhidrol 31%, 10...15 g/l silicat de sodiu de 38 degree Be, 30...50 g/l uree, sunt stoarse la un grad de stoarcere efectiv de 70...100% si tratate termic, o durata de maximum 60 min, cu ajutorul microundelor de frecventa înalta care actioneaza asupra tesaturii depuse în forma rolata în latime într-o incinta de tratare închisa.The invention relates to an alkaline treatment process, along with the bleaching of fabrics from a mixture of cellulosic fibers with polyesters, and consists in the fact that in order to reduce the thermal energy consumption and to increase the productivity, labor, raw fabrics or loose, ground and temofixed impregnated with water with a solution containing 60 ... 100 g / l caustic soda, 2 ... 10 g / l calcined soda, 2 ... 10 g / l boiling detergent, 10 ... 20 ml / l . Perhydrol 31%, 10 ... 15 g / l Sodium Silicate of 38 degree Be, 30 ... 50 g / l urea, are squeezed to an effective 70 ... 100% squeeze and heat treated up to a maximum of 60 minutes with the help of high-frequency microwaves acting on the fabrics deposited in the shape rolled in width in a closed treatment enclosure.
