Description

Verfahren zum Appretieren von Fasermaterial Es wurde gefunden, daß man Fasermaterial waschecht appretieren kann, wenn man es mit wäßrigen Lösungen tränkt, die saure Kondensationsmittel und Mischpolymerisate aus a, ß-ungesättigten Carbonsäureamiden und ungesättigten Aldehyden enthalten, trocknet und dann kurze Zeit auf Temperaturen über ioo°' erhitzt.Method of sizing fibrous material It has been found that you can finish fiber material washable if you do it with aqueous solutions soaks, the acidic condensation agents and copolymers of a, ß-unsaturated Containing carboxamides and unsaturated aldehydes, dries and then brief Time heated to temperatures above 100 ° '.

Als saure Kondensationsmittel eignen sich z. B. Aluminium- und Zinkchlorid, Salpetersäure, Ammonium-, Harnstoff- oder Aluminiumnitrat.Suitable acidic condensing agents are, for. B. aluminum and zinc chloride, Nitric acid, ammonium, urea or aluminum nitrate.

Geeignete Mischpolymerisate sind z. B. die aus Acryl- oder Methacrylsäureamid einerseits, Crotonaldehyd oder Vinylbenzaldehyd andererseits, gegebenenfalls in Gegenwart von indifferenten Lösungsmitteln, wie N-Methylpyrrolidon, Dimethylformamid oder Dioxan, unter der katalytischen Wirkung von Peroxyden oder Persalzen erhältlichen wasserlöslichen Produkte.Suitable copolymers are, for. B. from acrylic or methacrylic acid amide on the one hand, crotonaldehyde or vinylbenzaldehyde on the other hand, optionally in Presence of inert solvents such as N-methylpyrrolidone, dimethylformamide or dioxane, obtainable under the catalytic action of peroxides or persalts water soluble products.

Geeignetes Fasermaterial sind Fasern, Garne, Gewebe, Gewirke, Folien oder sonstige Gebilde aus Baumwolle, Hydratcellulose, Zellwolle, Mischgewebe oder Papier.Suitable fiber materials are fibers, yarns, woven fabrics, knitted fabrics, foils or other structures made of cotton, hydrate cellulose, rayon, blended fabric or Paper.

Beispiel Man imprägniert Zellwollgewebe mit einer wäßrigen Lösung, die im Liter ioo g des durch Polymerisation von ioo Gewichtsteilen Acrylsäureamid mit 2o Gewichtsteilen Crotonaldehyd in 5o Gewichtsteilen N-Methylpyrrolidon und 50 Gewichtsteilen Wasser durch Zusatz von 2 Gewichtsteilen Ammoniumpersulfat erhaltenen Reaktionsgemisches sowie - 3 g Harnstoffnitrat enthält, quetscht ab, trocknet bei 8d° und erhitzt auf 1q.0°. Das: Gewebe erhält eine gute Fülle. Die Appretur ist gegen mehrere Kochwäschen beständig.Example One impregnates viscose tissue with an aqueous solution, that per liter of ioo g of acrylic acid amide by polymerization of 100 parts by weight with 2o parts by weight of crotonaldehyde in 5o parts by weight of N-methylpyrrolidone and 50 parts by weight of water by adding 2 parts by weight Ammonium persulfate obtained reaction mixture as well as - contains 3 g urea nitrate, squeezes off, dries at 8d ° and heated to 1q.0 °. That: tissue gets a good fullness. the The finish is resistant to multiple boil washes.

Verwendet man zum Appretieren eine Lösung, die nicht das Mischpolymerisat, sondern die monomeren Einzelkomponenten enthält, so erhält man keine waschechte Appretur.If a solution is used for finishing that is not the copolymer, but contains the individual monomeric components, none of them are washable Finish.
