Description
Badania lat ostatnich wykazaly, ze dwutlenek chloru na niektóre ciala prawie zupelnie nie dziala, wtedy gdy niektóre ciala organiczne silnie niszczy. W pewnych warunkach dwutlenek chloru nie niszczy np, drzewnika, natomiast szybko niszczy barwniki, które znajduja sie w surowych materjalach wlókienniczych, jak np, w ba¬ welnie, lnie, jucie, drzewiniku i tym podob¬ nych materjalach.Na tej podstawie, jest oparty wynale¬ ziony sposób, wedlug którego wlókna luzne, przedzone badz tkane, drzewnik, papier i tym podobne materjaly, sa traktowane za- pomoca dwutlenku chloru w stanie gazo¬ wym, lub roztworu dwutlenku chloru.Dwutlenek chloru mozna wy tworzyc jakimkolwiek badz znanym sposobem, np, dzialajac kwasem siarkowym badz -szcza¬ wiowym na chloran potasowy, O ile na czesc barwników dwutlenek chloru dzia¬ lalby bezskutecznie, to mozna wybtelic ma¬ terial calkowicie przez dodanie dwutlenku wodoru, nadtlenków, nadsoli badz nad¬ manganianu. Nadmiar dwutlenku chloru o- raz dluzsze jego dzialanie nie szkodzi wlók¬ nom tak, jak dzialanie innych bielników.Przyklad bielenia tkanin bawelnianych: Przed bieleniem tkanine uprzednio traktu¬ jemy tak jak zazwyczaj, potem kladziemy ja do kapieli, do któreji badz doprowadza¬ my dwutlenek chloru, badz w której jesten roztworzony. Pozadane jest przerzuca¬ nie tkaniny w kapieli. Jezeli ogrzac kapiel bielaca, to mozna zwiekszyc dzialanie bie¬ lace dwutlenku chlorku i skrócic trwanie bielenia. Gdy tkanina jest dostatecznie wy¬ bielona, zostaje ona wyplókana. Nalezy jed¬ nak przedtem dzialac: na nia nadtlenkiem. PLResearch in recent years has shown that chlorine dioxide has almost no effect on some bodies, while some organic bodies are strongly damaged. Under certain conditions, chlorine dioxide does not destroy, for example, wood, but it quickly destroys dyes that are found in raw textile materials, such as, for example, cotton, flax, yut, wood and the like. invented method, according to which loose, hollow or woven fibers, wood, paper and the like are treated with gaseous chlorine dioxide or a solution of chlorine dioxide. Chlorine dioxide can be produced by any known method, for example, by treating potassium chlorate with sulfuric or oxyic acid. While chlorine dioxide is unsuccessful for some of the dyes, the material can be completely exposed by adding hydrogen dioxide, peroxides, persalts or per manganate. Excess chlorine dioxide and its longer duration of action does not harm the fibers, as does other bleaching agents. Example of bleaching cotton fabrics: Before bleaching the fabric, first treat the fabric as usual, then put it in a bath, to which it is supplied with the dioxide. chlorine, or in which it is dissolved. It is desirable to turn the fabric over in the bath. If you warm the bleaching bath, you can increase the bleaching effect of the chloride dioxide and shorten the bleaching time. When the fabric is sufficiently bleached, it is spilled. However, it must first be treated with peroxide. PL
