- Die folgenden Beispiele veranschaulichen die Erfindung. Teile bedeuten Gewichtsteile und Prozente Gewichtsprozente.
- Drei Stränge aus Polypropylengarn der Feinheit Nm 60/1 z.B. Polycolon® von je 5 g in den Farben weiss (Muster A, spinnmassenaufgehellt), marineblau (Muster B, spinnmassengefärbt) und dunkelblau (Muster C, spinnmassengefärbt) werden bei einem Flottenverhältnis von 1:30 in drei Flotten behandelt, die folgende Zusätze enthalten:
1 g/l Na₂CO₃ kalz.
0,5 g/l eines nicht-ionischen Tensides und
1 Gew.% bezogen auf das Garngewicht der Verbindung der Formel (100) - Man geht mit den Garnen bei 50°C in diese Behandlungsflotte (pH-Wert 10,3) ein, erwärmt in 15 Min. auf 90°C und belässt 30 Min. bei dieser Temperatur. Schliesslich wird gründlich warm und kalt gespült und anschliessend bei 60°C getrocknet.
- Zur Bestimmung der photochemischen Stabilität der Garne A - C werden je ca. 25 Lagen auf einen Belichtungskarton von 13 x4,3 cm gewickelt und nach DIN 75.202 (Entwurf 1/88) bzw. nach SN-ISO 105-BO2 (Xenontest) heissbelichtet. Nach dem Belichten wird nach SNV 197.461 die Reissfestigkeit und die Dehnung der einzelnen Garne ermittelt, wobei die Ausgangsmaterialien als Standard und die belichteten, unbehandelten Garne als Bezugsgrössen gelten.
- Die Resultate sind in der nachfolgenden Tabelle I zusammengefasst.
Tabelle I Muster Reissfestigkeit/Dehnung in (%) Material unbehandelt Material nachstabilisiert -*) FAKRA 48h FAKRA 144h FAKRA 48h FAKRA 144h A 100/100 83 /78,9 68,8/53,7 99,1/93,3 89,2/80,6 B 100/100 38,2/35,3 zerstört 79,6/90,1 67,6/68,4 C 100/100 37,4/40,2 zerstört 100 /89,0 75,2/64,0 *) Standard Muster Reissfestigkeit/Dehnung in (%) Material unbehandelt Material nachstabilisiert -*) Xenon 500h Xenon 1000h Xenon 500h Xenon 1000h A 100/100 100/82 77/76 100/91 93/91 B 100/100 69/68 zerstört 89/100 88/93 C 100/100 62/66 17/23 84/87 87/86 *) Standard - Es ist ersichtlich, dass das weisse Garn deutlich, die beiden gefärbten Garne massgeblich in der Licht-/Wärmestabilität verbessert wurden.
- Man verfährt wie in Beispiel 1 beschrieben, verwendet jedoch anstelle der Verbindung (100) die Verbindung der Formel (200)
- Die Resultate sind in der nachfolgenden Tabelle II zusammengefasst.
Tabelle II Muster Reissfestigkeit/Dehnung in (%) Material unbehandelt Material nachstabilisiert -*) FAKRA 48h FAKRA 144h FAKRA 48h FAKRA 144h D 100/100 83 /78,9 68,8/53,7 96,6/97,6 96,2/87,9 E 100/100 38,2/35,3 zerstört 79,2/85,5 72,7/70,1 F 100/100 37,4/40,2 zerstört 100/100 71,4/61,6 *) Standard Muster Reissfestigkeit/Dehnung in (%) Material unbehandelt Material nachstabilisiert -*) Xenon 500h Xenon 1000h Xenon 500h Xenon 1000h D 100/100 100/82 77/76 88/94 89/95 E 100/100 69/68 zerstört 100/93 95/85 F 100/100 62/66 17/23 92/100 84/96 *) Standard - Auch bei Verwendung der Verbindung (200) wurde bei allen 3 Mustern eine gute bis sehr gute Nachstabilisierung gegen einen Licht-/Hitzeabbau der Faser erhalten.
- Je 2 Muster von 10 g eines ®Maraklon-Stapelgewebes (unstabilisiertes Polypropylen) werden wie folgt aufgehellt bzw. aufgehellt und stabilisiert: Muster I wird in einer Flotte folgender Zusammensetzung, behandelt:
1 g/l Na₂CO₃
0,5 g/l eines nicht-ionischen Tensides und
0,1 Gew.% bezogen auf das Gewebegewicht, der Verbindung der Formel (3) - Als 20 %-ige Sandmahlung mit dem sulfonierten Kondensationsprodukt aus Naphthalin und Formaldehyd als Dispergator, im Gewichtsverhältnis 2:1.
- Muster II wird in einer Flotte behandelt, die zusätzlich noch 1 Gew.% bezogen auf das Gewebegewicht der Verbindung (100) enthält, die als 20 %ige Formulierung vorliegt.
- Die Behandlung erfolgt wie in Beispiel 1 vermerkt.
- In beiden Fällen resultieren Aufhellungen mit einem guten Weissgrad. Unterwirft man die Muster I und II einer Belichtung, z.B. einer Belichtung nach DIN 75 202 (Entwurf 1/88), so genügen bei Muster I bereits 20 Stunden Belichtungszeit, um zu einem völlig zerstörten Textilmaterial zu gelangen. Das stabilisierte Muster II ist dagegen nach einer (Heiss-)Belichtungszeit von 144 Stunden noch intakt und hoch reissfest.
- Je 2 Muster von 10 g eines ®Maraklon-Stapelgewebes (unstabilisiertes Polypropylen) werden gebleicht bzw. aufgehellt und stabilisiert, in dem man sie
bei 50°C, bei einem Flottenverhältnis von 1:25, in zwei Bleichbädern einbringt, die jeweils pro Liter
2 g Natriumchlorit (80 %),
2 g Natriumnitrat,
1,5 ml Ameisensäure (85 %) und
0,5 g eines nichtionischen Tensides
und das Bad Nr. 2 zusätzlich noch 0,1 Gew.%, bezogen auf das Gewebegewicht, des Aufhellers der Formel (300)
(als 20%ige Dispersion eigesetzt) enthalten. Man erhitzt die Bleichbäder innerhalb von 30 Minuten auf 85°C und behandelt 60 Minuten bei dieser Temperatur. Alsdann werden die Bäder abgekühlt und die Substrate zweimal kalt gespült, zentrifugiert und getrocknet. - Die beiden Muster werden nun halbiert. Die Teile (a) werden nicht weiterbehandelt, die Teile (b) dagegen, bei einem Flottenverhältnis 1:25, in einem Bad behandelt, das pro Liter
0,5 g eines nichtionischen Tensides,
0,5g Natriumkarbonat calc. und
1 Gew.% bezogen auf das Gewebegewicht, der Verbindung der Formel (100) als 20%ige Dispersion
enthält. Man erhitzt das Bad auf 50°C, erhöht die Temperatur innerhalb von 10 Minuten auf 75°C und behandelt 30 Minuten bei dieser Temperatur. Alsdann wird das Bad abgekühlt und die Substrate kalt gespült und getrocknet. - In beiden Fällen resultieren Aufhellungen mit einem sehr guten Weissgrad. Unterwirft man die Muster 1a, 1b, 2a und 2b einer Belichtung von 350 Stunden nach SN-ISO 105-BO2 (Xenontest) und von 72 Stunden nach DIN 75 202 (Entwurf 1/88; Fakratest), so weisen die Muster 1a und 2a eine geringe bzw. keine, die Muster 1b und 2b dagegen eine gute mechanische Festigkeit auf.
- Man verfährt wie in Beispiel 4 angegeben mit dem Unterschied, dass statt Verbindung (100) 1 Gew.% bezogen auf das Gewebe, als 50%ige Emulsion, der Verbindung (200) eingesetzt wird.
- Es resultieren auch hier 4 Aufhellungen mit hohem Weissgrad. Das aufgehellte Fasermaterial der Muster 1a und 2a sind ebenfalls nur mangelhaft licht- und wärmestabil, während das Fasermaterial der Muster 1b und 2b eine 72stündige Heissbelichtung nach DIN 75.202 (Entwurf 1/88) unzerstört überstehen.
-
- Es werden Aufhellungen mit einem ähnlichen Weissgrad, wie in Beispiel 4 beschrieben, erhalten. Das aufgehellte Gewebe ist jedoch erst nach der Stabilisierung mit der Verbindung der Formel (200) lichtstabil, d.h. nach dem Belichten noch mechanisch belastbar.
- Drei Muster à 10 g eines ®Maraklon-Gewebes werden bei einem Flottenverhältnis von 1:20 in einem Bad behandelt, das pro Liter 0,5 g eines nichtionogenen Tensides,
1,0 g Ammoniumsulfat
sowie 1 % folgender Verbindungen in formulierter Form enthält: - In einem Färbeapparat (z.B. ®AHIBA-Färbegerät) geht man bei 50°C mit dem Gewebe ein, erhöht die Temperatur innerhalb 30 Minuten auf 90°C und behandelt 30 Minuten bei dieser Temperatur. Danach wird das Bad auf 60°C abgekühlt und das behandelte Gewebe warm und kalt gespühlt und getrocknet.
- Unterwirft man das Ausgangsmaterial und die so behandelten Muster 144 Stunden lang dem Heissbelichtungstest nach DIN 75.202 (Fakratest), so ist das behandelte Gewebe noch völlig intakt, während das unbehandelte beim Berühren zerfällt.
