Description

Uprawniony z patentu: Artos Dr. Ing. Meier-Windhorst Kommandit- gesellschaft Hamburg (Republika Federalna Niemiec) Sposób wytwarzania sztucznej skóry Przedmiotem wynalazku jest sposób wytwarza¬ nia sztucznej skóry zwlaszcza na obuwie.Znane sa rózne sposoby wytwarzania sztucznej skóry. Wszystkie sztuczne skóry wytwarzane zna¬ nymi sposobami posiadaja jednak ze wzgledu na ich zastosowanie bezposrednio na material wierzch¬ ni do obuwia wiecej lub mniej niedogodnosci, po¬ niewaz zdarza sie czesto, ze ta sztuczna skóra nie posiada dostatecznej rozciagliwosci lub nie jest wy¬ starczajaco zdolna do przepuszczania pary, albo nie jest w stanie do przejecia wystarczajacej ilosci wilgotnosci, albo tez nie jest w dostatecznym stop¬ niu elastyczna.Zadaniem wynalazku jest przeto stworzenie sztucznej skóry, która posiadalaby w kazdych prak¬ tycznie warunkach dobre i uzyteczne wlasnosci skó¬ ry naturalnej, zwlaszcza w przypadku jej zasto¬ sowania na obuwie., Zadanie to zgodnie z wynalazkiem zostalo roz¬ wiazane w ten sposób, ze runo wlókien poddaje sie wykurczeniu do 30%, nastepnie impregnuje sie je calkowicie laktesem po czym poddaje sie koagulacji przy temperaturze 40 do 45°C oraz wymywaniu emulgatorów lub utwardzacza w kapieli kaskado¬ wej i wymywaniu soli. Po tym wszystkim runo pod¬ daje sie suszeniu oraz obróbce wygladzajacej i spilsniajacej w plaszczyznie runa a wreszcie na jedna strone runa natryskuje sie warstwe po¬ wierzchniowa po czym poddaje sie ostatecznemu suszeniu. 15 20 25 30 Inna postac wykonania wynalazku polega na tym, ze runo wlókien poddaje sie wykurczaniu do 30°/o, nastepnie impregnuje sie je calkowicie poliureta¬ nem, przeprowadza sie przez kapiel do koagulacji poliuretanu a na koniec przez kapiel do wymywa¬ nia rozpuszczalnika. Po tym wszystkim runo pod¬ daje sie suszeniu oraz obróbce wygladzajacej i spilsniajacej w plaszczyznie runa a wreszcie na jedna strone runa natryskuje sie wartwe powierzch¬ niowa po czym poddaje sie ostatecznemu susze¬ niu.Natryskiwanie wstegi materialu w celu wytwo¬ rzenia warstwy powierzchniowej dokonuje sie szczególnie w korzystny sposób w wielu nastepu¬ jacych po sobie operacjach natryskiwania przy czym do natryskiwanej substancji dodaje sie rózne ilosci powietrza. Przez to mozliwe jest uzyskanie w warstwie powierzchniowej zróznicowanej struk¬ tury, która po stronie zwróconej do runa jest luz¬ niejsza niz na powierzchni zewnetrznej.Wynalazek jest wyjasniony blizej na przykladach wykonania uwidocznionych na rysunku schematycz¬ nym, na którym fig. 1 przedstawia proces trakto¬ wania tasmy runa spoiwem w postaci lateksu i proces termokoagulacji po pelnej impregnacji, fig. 2 — proces traktowania tasmy runa lateksem i wprowadzenie tej tasmy do kapieli stracajacej a fig. 3 — proces obróbki, przy zastosowaniu poliure¬ tanu jako spoiwa. 82 24982 249 jednoczesnej obróbce cieplnej. Wreszcie zaopatruje sie tasme runa 10 jednostronnie w impergnacje koncowa, która nanosi sie przez natryskanie jej na te tasme. Natryskiwanie to odbywa sie za po- 5 moca kilku wlaczonych jedno za drugim urzadzen natryskowych 16 lub za pomoca urzadzenia na¬ tryskowego 17 lub 18, w którym znajduja sie umieszczone jedna za druga glowice rozpylajace.Po wyjsciu tasmy runa z tych urzadzen natrysko- 10 wych moze byc podjete celowo jeszcze suszenie koncowe.Na wszytkich figurach sa te same czesci za¬ opatrzone w te same oznaczenia liczbowe.Jak wynika z rysunku, uksztaltowana tasme ru¬ na 10 wprowadza sie najpierw do kapieli wykur- czajacej 11. Tu podejmuje sie wykurczanie wlókien, które sluzy do rozprezania tasmy runa i które nie powinno przekroczyc wartosci 30%. Wraz z wykur- czaniem tasme runa wprowadza sie do urzadzenia impregnujacego 12, w którym przeprowadza sie pelna impregnacje. Po wycisnieciu tasmy za pomo¬ ca urzadzenia wyciskajacego 13 moze nastapic przed wprowadzeniem tasmy do suszarki 14 stosowanie do zastosowanego spoiwa, rózna obróbka posrednia.Polega ona w przykladzie, przedstawionym na fig. 1 na tym, ze tasme run^ 10 przeprowadza sie naj¬ pierw przez suszarke wstepna 19, w której podej¬ muje sie koagulacje w temperaturze od 40 do 45°C.Z kolei po koagulacji tasme runa wprowadza sie do kapieli pluczacej 20, sluzacej do wymywania emulgatorów.W przykladzie wykonania przedstawionym na fig. 2, w którym stosuje sie równiez lateks jako spoiwo, obróbka posrednia polega na tym, ze po wycisnieciu tasmy na urzadzeniu wyciskajacym 13 tasme runa 10 wprowadza sie do kapieli wytraca¬ jacej w celu koagulacji lateksu, a nastepnie po wycisnieciu posrednim do nastepnej kapieli plu¬ czacej, w celu wyplukania soli.W przykladzie wykonania, przedstawionym na fig. 3, w którym stosuje sie poliuretan jako spoiwo, tasme runa 10 wprowadza sie po jej wycisnieciu za pomoca urzadzenia wyciskajacego 13 do kapieli koagulujacej, a nastepnie po wycisnieciu posrednim do kapieli w celu wyplukania rozpuszczalników.W suszarce 14, przez która przechodzi tasma runa 10, odbywa sie suszenie na okolo 15 lub 10% wil¬ gotnosci. W koncu tasme runa poddaje sie po¬ wierzchniowemu wygladzeniu i spilsnieniu w urza¬ dzeniu wygladzajacym i spilsniajacym 15, przy PL PL
