798), dass[1967], S. 215 bis 217) mit einem Brennwinkel von etwa 250 gute Flammschutzeffekte.
Beispiel 2 : Ein Popelingewebe (180 g/m2), bestehend aus 50% Polyäthylenglykolterephthalat und 50% Baumwolle (Kette gezwirnt, Schuss als Einfachgarn), dass mit Indanthrenblau RK (Colour Index Nr. 70000) gefärbt ist, wird mit einer wässerigen Lösung von 180 g/l des Ammoniumsalzes der Bis-hydroxymethylphosphinsäure, wie in Beispiel 1, imprägniert, abgequetscht und getrocknet. Man erhält einen weichen Griff und eine gute Flammfestausrüstung (7, 5 cm Einbrennlänge, Brennwinkel etwa 270).
Zu ebenso guten Ergebnissen kommt man bei gleichartiger Imprägnierung eines Flanells (190 g/m2), der aus 80% Polyäthylenglykolterephthalat und 20% Viskosezellwolle besteht und mit Indanthrenblau RK bedruckt ist, und von einem Dekorationsstoff in Satin-Art (220 g/m2) bestehend aus 67% Polyäthylenglykolterephthalat und 33% Baumwolle.
Beispiel 3 : Eine gewirkte Kettstuhlware (200 g/m2), bestehend aus 50% Polyäthylenglykolterephthalat und 50% Baumwolle, wird auf der Haspelkufe mit einer wässerigen Lösung von 180 g/l des Ammoniumsalzes der Bis-hydroxymethylphosphinsäure bei gewöhnlicher Temperatur imprägniert. Dann wird auf etwa 80% Gewichtszunahme abgeschleudert und bei etwa 800C getrocknet. Das Gewirke zeigte einen weichen Griff und mit etwa 8 cm Einbrennlänge und einem Brennwinkel von etwa 250 eine gute Flammfestausrüstung.

798) that [1967], pp. 215 to 217) with a focal angle of about 250 good flame retardant effects.
Example 2: A poplin fabric (180 g / m2), consisting of 50% polyethylene glycol terephthalate and 50% cotton (twisted warp, weft as single yarn) that is dyed with indanthrene blue RK (Color Index No. 70000), is mixed with an aqueous solution of 180 g / l of the ammonium salt of bis-hydroxymethylphosphinic acid, as in Example 1, impregnated, squeezed off and dried. The result is a soft handle and good flame retardancy (7.5 cm burn-in length, burn angle about 270).
Equally good results are obtained with the same type of impregnation of a flannel (190 g / m2), which consists of 80% polyethylene glycol terephthalate and 20% viscose cellulose and is printed with indanthrene blue RK, and a decorative fabric in satin type (220 g / m2) Made of 67% polyethylene glycol terephthalate and 33% cotton.
Example 3: A knitted warp loom fabric (200 g / m2), consisting of 50% polyethylene glycol terephthalate and 50% cotton, is impregnated on the reel vat with an aqueous solution of 180 g / l of the ammonium salt of bis-hydroxymethylphosphinic acid at normal temperature. Then it is centrifuged to a weight increase of about 80% and dried at about 80.degree. The knitted fabric was soft to the touch and, with a burn-in length of about 8 cm and a burning angle of about 250, had good flame-retardant properties.
