Beiden Methoden zur Hydrophobierung ist gemeinsam, dass das Lösemittel so gewählt wird, dass die Fasern partiell gelöst werden.

Außerdem kann durch Behandlung mit organischen Lösemitteln die mechanische Festigkeit der Fasern beeinflusst werden.Both methods of hydrophobing have in common that the solvent is chosen so that the fibers are partially dissolved. For this it is necessary to use large amounts of organic solvent, which is undesirable in many cases. In addition, by treatment with organic solvents, the mechanical strength of the fibers can be influenced.

Man vermischte die Komponenten gemäß Tabelle 1, füllte mit Wasser auf einen Liter auf und erhielt die erfindungsgemäßen wässrigen Flotten WF.1 bis WF.8, die zur Behandlung von textilen Substraten eingesetzt wurden.
Allgemeine Vorgehensweise für die erfindungsgemäße Behandlung von Textil am Beispiel von Polyestergewebe:
- Ein Polyestergewebe mit einem Flächengewicht von 220 g/m2 wurde mit einer erfindungsgemäßen wässrigen Flotte gemäß Tabellen 1 und 2 auf einem Foulard (Hersteller Fa. Mathis, Typ Nr. HVF12085) behandelt. Der Anpressdruck der Walzen betrug 2,1 bar. Es resultierte eine Flottenaufnahme von 40%. Die Auftraggeschwindigkeit betrug 2 m/min. Anschließend wurde das behandelte Polyestergewebe eine Minute lang bei 120°C auf einem Spannrahmen getrocknet. Die abschließende thermische Behandlung erfolgte über einen Zeitraum von einer Minute bei 185°C unter Umluft. Man erhielt erfindungsgemäße behandelte Polyestergewebe PES.1 bis PES.8.
- A polyester fabric having a weight per unit area of 220 g / m 2 was treated with an aqueous liquor according to the invention according to Tables 1 and 2 on a padder (manufacturer Fa. Mathis, type no. HVF12085). The contact pressure of the rolls was 2.1 bar. This resulted in a fleet intake of 40%. The application speed was 2 m / min. Subsequently, the treated polyester fabric was dried for one minute at 120 ° C on a tenter. The final thermal treatment was carried out over a period of one minute at 185 ° C under circulating air. Treated polyester fabrics PES.1 to PES.8 according to the invention were obtained.
Die anwendungstechnischen Eigenschaften gehen aus Tabelle 2 hervor.
Die zu untersuchende erfindungsgemäß behandelte Textilprobe wurde manuell gespannt und mit Nadeln auf einem ebenen Holzbrett fixiert, dessen Neigung stufenlos von 1° bis 90° eingestellt werden konnte. Dann ließ man mit Hilfe einer Kanüle aus einer Höhe von 10 mm einzelne Wassertropfen auf die Textilprobe fallen. Die Tropfen hatten eine Masse von 4,7 mg. Durch schrittweises Senken des Neigungswinkels wurde der Neigungswinkel bestimmt, bei dem die Tropfen gerade noch abperlten und keine Adhäsion zu beobachten war. Die Ergebnisse finden sich in Tabelle 2.The textile sample to be tested according to the invention was tensioned manually and fixed with needles on a flat wooden board whose inclination could be adjusted continuously from 1 ° to 90 °. Then, with the help of a cannula from a height of 10 mm, individual drops of water were dropped onto the textile sample. The drops had a mass of 4.7 mg. By gradually lowering the angle of inclination, the angle of inclination was determined at which the drops just bared and no adhesion was observed. The results are shown in Table 2.
Abperleffekt, Aufnahme (Wasseraufnahme) und Durchlass (Wasserdurchlässigkeit) beziehen sich jeweils auf Wasser. Die Wasseraufnahme wurde nach Bundesmann, DIN 53888, geprüft.Beading effect, absorption (water absorption) and passage (water permeability) refer to water. The water absorption was tested according to Bundesmann, DIN 53888.
Die Wassersäule wurde nach DIN EN 20811 bestimmt.The water column was determined according to DIN EN 20811.
Zur Durchführung des Honigtests wurde jeweils ein frischer Waldblütenhonig aus einer Höhe von 5 cm mit einer Pipette auf erfindungsgemäßes Textil getropft, das in einem Winkel von 20° eingespannt war. Der Honig verhielt sich, wie aus der Tabelle ersichtlich. Dabei bedeuten:
- ++
- läuft in runden Tropfen ab ohne Rückstand,
- +
- läuft ab, bildet kleine Nase beim Laufen
- 0
- läuft ab, bildet sichtbare Nase beim Laufen
- -
- benetzt
- ++
- runs off in round drops without residue,
- +
- runs off, makes little nose while running
- 0
- expires, forms visible nose while running
- -
- wetted
