• This foam is applied to the pile side of the ppichs previously impregnated Te, wherein the foam applicator 145%, based on the weight of the dry carpet weight,.
• the layer height of the foam is 9 mm.
• the carpet is then guided into a horizontal damper at a speed of 8 m / minute and treated with saturated steam at 98 ° C. for 4 minutes, then rinsed and dried. A level, blue-colored carpet with good light and wet fastness properties is obtained.
• 1.35 g / 1 of the blue mixture instead of 1.35 g / 1 of the blue mixture, 1.35 g / 1 of a further blue dye mixture consisting of 56 parts of the dye of the formula (13) and 44 parts of a dye of the formula is used so you get a blue, even carpet dyeing with otherwise the same procedure.

• Example 2 Contains acetic acid to adjust the liquor to a pH of 5.8. Then, as described in Example 1, an aqueous liquor which also contains the above additives is foamed. The degree of foaming is 1: 9. The foam half-life is 5 minutes.
• This foam is applied to the pile side of the carpet that has already been impregnated, the foam application being 70%, based on the weight of the dry carpet.
• the carpet is then fed into a horizontal damper at a speed of 10 m / minute and treated with saturated steam at 98 ° C. for 4 minutes, then rinsed and dried.

• Example 13 A wool cut pile carpet with a weight of 1150 g / m 2 is continuously pre-wetted in an aqueous liquor which contains 2 g of bis-octyl sulfosuccinate (sodium salt) per liter and is suctioned off to absorb a liquor of 40% by weight.
• the degree of foaming is 1: 8.

• This foam is then applied from a foam container, which has an adjustable doctor blade for setting the desired foam thickness, via an application roller by means of a chute to the pole side of the carpet running through the dyeing system.
• the goods run speed is 8 m / minute.
• the layer height of the foam is 7 mm.
• the color foam application is 150%.
• the carpet then goes through a vacuum passage in which the foam layer is partially sucked into the carpet from the back (negative pressure of 0.1 bar), which reduces the height of the foam layer somewhat.
• the carpet then runs over a transport roller to a damper, the foam layer on the carpet disintegrating even before the damper is reached.
• the foam is re-foamed at 98 ° C for 5 to 10 seconds.
• the carpet is then treated with saturated steam at 98 ° C for 5 minutes.
• the carpet is then washed cold and dried.
• Example 14 A polyamide 6,6 carpet product with a weight of 550 g / m 2 is continuously pre-wetted in an aqueous liquor which contains 1 g of the adduct of 9 mol of ethylene oxide with 1 mol of nonylphenol per 1 liter and for a liquor pickup sucked off by 45 percent by weight.
