Verfahren zur Herstellung überfärbeechter Färbungen auf Acetylcellulose sowie Polyamiden oder Polyurethanen Von den in Herren- und Damenstoffen aus Wolle und Wolle-Zellwoll-Mischungen gebräuchlichen farbigen Effektfäden aus Acetatkunstseide oder linearen Polyamiden oder Polyurethanen wird ein hoher Stand der Gesamtechtheiten und insbesondere eine sehr gute Überfärbeechtheit verlangt. Die Anzahl blauer Farbstoffe, welche diesen Ansprüchen genügen, ist sehr gering.Process for the production of dye-fast dyeings on acetyl cellulose as well as polyamides or polyurethanes of those in men’s and women’s woolen fabrics and wool-rayon blends of the usual colored effect threads made of acetate artificial silk or linear polyamides or polyurethanes will have a high level of overall fastness and in particular a very good fastness to overdyeing is required. The number of blue dyes, which meet these requirements is very low.
Es wurde nun gefunden, daB man blaue Färbungen mit guten Gesamtechtheiten und sehr guter Überfärbeechtheit auf Acetatkunstseide sowie auf Polyamiden oder Polyurethanen erhält, wenn man die Azofarbstoffe aus diazotiertem i-Amino-4-(2', 5'-dimethoxyphenyl - i' - azo) -naphthalin oder i -Aminoq.- (2'- methyl - q.'- methoxyphenyl-i'- azo) - naphthalin und i - (2', 3'- Oxynaphthoylamino) - 2-methoxybenzol, -2-methyl-q.-methoxybenzol oder -2, 4.-dimethoxy-5-chlorbenzol nach der unter dem Namen Einbadverfahren bekanntgewordenen Methode auf der Faser entwickelt. Beispiel i i kg Acetatkunstseide wird i1/2 Stunden bei 75° in einem Bade behandelt, welches 150 g eines Kondensationsproduktes aus höhermolekularen Fettsäuren und EiweiBabbauprodukten, 30 ccm Ammoniak 25°/oig und 3oo g Kochsalz in 30 1 Flotte enthält und in das eine heiße Lösung von 9 g i-Amino-q.-(2',5'-dimethoxyphenyl-i'-azo)-naphthalin und 15 g 1-(2', 3'-Oxynaphthoylamino)-2-methy1-q.-methoxybenzol in einem Gemisch von 6 ccm Natronlauge 38° Be, 9o g Monoäthanolamin und 15 ccm Wasser eingerührt wurde.It has now been found that blue dyeings with good overall fastness properties and very good over-dyeing fastness are obtained on acetate rayon and on polyamides or polyurethanes if the azo dyes are obtained from diazotized i-amino-4- (2 ', 5'-dimethoxyphenyl-i'-azo ) -naphthalene or i-aminoq.- (2'- methyl - q .'- methoxyphenyl-i'- azo) - naphthalene and i - (2 ', 3'-oxynaphthoylamino) - 2-methoxybenzene, -2-methyl- q.-methoxybenzene or -2, 4.-dimethoxy-5-chlorobenzene, developed on the fiber using the method known as the single bath method. Example ii kg of acetate rayon is treated for 1/2 hours at 75 ° in a bath which contains 150 g of a condensation product of higher molecular weight fatty acids and protein degradation products, 30 ccm of 25% ammonia and 300 g of table salt in 30 l of liquor and in which a hot solution of 9 g of i-amino-q .- (2 ', 5'-dimethoxyphenyl-i'-azo) -naphthalene and 15 g of 1- (2', 3'-oxynaphthoylamino) -2-methy1-q.-methoxybenzene in a mixture of 6 cc sodium hydroxide solution 38 ° Be, 90 g monoethanolamine and 15 cc water was stirred in.
Man spült und diazotiert ?112 Stunde bei 15° in einem Bade, welches 3o g Natriumnitrit und 150 ccm Salzsäure 2o° Be in 30 1 Wasser enthält.It is rinsed and diazotized for 112 hours at 15 ° in a bath which Contains 30 g sodium nitrite and 150 cc hydrochloric acid 20 ° Be in 30 liters of water.
Anschließend wird bei Gor mit i2o g Natriumacetat in 3o 1 Wasser nachbehandelt, heiß geseift und gespült. Man erhält ein Dunkelblau von guter Wasch- und CTberfärbeechtheit. Beispiel 2 i kg einer Polyamidfaser wird i1/2 Stunden bei 75° in einem Bade gefärbt, welches in 301 Flotte 150 g eines Kondensationsproduktes aus höhermolekularen Fettsäuren und Eiweißabbauprodukten, 30 ccm Ammoniak 25°/oig, 300 g Kochsalz und eine heiße Lösung von 3 g 1-(2', 3'-Oxynäphthoylamino)-2-methoxybenzol und 2 g i-Amino-4-(2', 5'-dimethoxyphenyli'-azo)-naphthalin in einem Gemisch von o,8 ccm Natronlauge 38- B6 und 18 ccm Diäthanolamin enthält.Then Gor is treated with 12o g sodium acetate in 3o 1 water, soaped with hot water and rinsed. A dark blue of good fastness to washing and dyeing is obtained. Example 2 1 kg of a polyamide fiber is dyed for 1/2 hours at 75 ° in a bath containing 150 g of a condensation product of higher molecular weight fatty acids and protein degradation products, 30 ccm of 25% ammonia, 300 g of sodium chloride and a hot solution of 3 g 1- (2 ', 3'-Oxynäphthoylamino) -2-methoxybenzene and 2 g i-Amino-4- (2', 5'-dimethoxyphenyli'-azo) -naphthalene in a mixture of 0.8 ccm caustic soda 38- Contains B6 and 18 cc of diethanolamine.
Man spült kurz, diazotiert 1/2 Stunde in der Kälte in einem Bade, welches 6o g Natriumnitrit und 225 ccm Salzsäure 2o' B6 in 30 1 Wasser enthält und behandelt nach etwa 1/2 Stunde mit einer 6o° heißen Lösung von i2o g Natriumacetat in 30 1 Wasser nach.One rinses briefly, diazotizes 1/2 hour in the cold in a bath, which contains 60 g sodium nitrite and 225 cc hydrochloric acid 20 'B6 in 30 1 water and treated after about 1/2 hour with a 60 ° hot solution of 12o g sodium acetate in 30 l of water.
Anschließend wird bei etwa 8o bis 85° geseift und gespült. Man erhält ein grünstickiges Blau von guter Wasch-, Dekatur- und Überfärbeechtheit. Beispiel 3 i kg einer Polyamidfaser wird i1/2 Stunden bei 75° in einem Bade gefärbt, welches in 30 1 Flotte i5o g eines Kondensationsproduktes aus höhermolekularen Fettsäuren und Eiweißabbauprodukten, 30 ccm Ammoniak 25°/Qig, 300 g Kochsalz und eine heiße Lösung von 15 g 1- (ä', 3' - Oxynaphthoylamino)-2, 4-dimethoxy-5-chlorbenzol und 9 g i-Aminö-4-(2', 5'-dimethoxyphenyl-i'-azo)-naphthalin in 6 ccm Natronlauge 38° B6, 5o ccm Monoäthanolamin und 5o ccm Alkohol enthält.Then soap and rinse at around 8o to 85 °. A greenish blue of good fastness to washing, decatur and overstaining is obtained. EXAMPLE 3 i kg of a polyamide fiber is dyed for i 1/2 hours at 75 ° in a bath which is in 30 l liquor i5o g of a condensation product of higher molecular weight fatty acids and protein degradation products, 30 ccm ammonia 25 ° / Qig, 300 g common salt and a hot solution of 15 g of 1- (a ', 3' - oxynaphthoylamino) -2, 4-dimethoxy-5-chlorobenzene and 9 g of i-amino-4- (2 ', 5'-dimethoxyphenyl-i'-azo) -naphthalene in 6 ccm caustic soda 38 ° B6, 50 ccm monoethanolamine and 50 ccm alcohol.
Man spült kurz, diazotiert 1,f, Stunde in der Kälte in einem Bade, welches 6o g Natriumnitrit und 225 ccm Salzsäure 2o° B6 in 30 1 Wasser enthält und behandelt bei 6o' in einer Lösung von 120 g Natriumacetat in 30 1 Wasser nach. Anschließend wird heiß geseift. Man erhält ein grünstickiges Dunkelblau von guter Wasch-, Dekatur- und Überfärbeechtheit.One rinses briefly, diazotizes 1, f, hour in the cold in a bath, which contains 60 g sodium nitrite and 225 ccm hydrochloric acid 20 ° B6 in 30 l water and treated at 6o 'in a solution of 120 g of sodium acetate in 30 l of water. Afterward is soaped hot. A greenish dark blue of good washing, decaturation and color fastness.
Ersetzt man in obigen Beispielen das 1-Amino-4-(2', 5'-dimethoxyphenyl-i'-azo)-naphthalin durch eine entsprechende Menge i-Amino-4-(2'-methyl-4'-methoxyphenyl-i'-azo)-naphthalin und verfährt sonst wie angegeben, so erhält man ebenfalls blaue Färbungen, die sich durch gute Echtheitseigenschaften auszeichnen.In the above examples, 1-amino-4- (2 ', 5'-dimethoxyphenyl-i'-azo) naphthalene is replaced by an appropriate amount of i-amino-4- (2'-methyl-4'-methoxyphenyl-i'-azo) naphthalene and if you proceed as indicated, you will also get blue colorations, which are characterized by good fastness properties.
