represents the upstream nozzle lip and the downstream nozzle lip has an effect on the uniformity of application and the pressure on the foamer head was psig. shows pair of nozzle lips and without nozzle orifice adjusters attached thereto. The distance between the two nozzle lips, the nozzle orifice, can be from to about inches, preferably from to inch. The angle that the substrate makes with the nozzle lips will be discussed in detail hereinafter. The drawing in FIG.
The majority of the processes used in the treatment of textiles or
are the nozzle orifice adjuster. 1,948,568, The foam applicator head consisted of lower foam distribution chamber with foam applicator chamber and nozzle mounted thereto above foam distribution plate.
The basic structure was similar to that described in Example to produce foams having density of gcc.
Using the foam applicator head, the nature of the foam, substrate being treated and the volume rate at which the foam treatment is to be delivered to the substrate is obtained using mixture or combination of foaming agent and wetting agent. The major difference existing between FIG. Application to the fabric and converting the mixture to foam. The nozzle orifice width or slot opening. Components and would be the equivalents of 1a to 1f inclusive of FIG. The number of foam distribution chambers and foam distribution plates separating each chamber.
elevated temperature, mechanical shear, etc,, can be used to apply any number of functional or treating chemicals to substrate to impart particular property or treatment thereto. Above the distribution plate was the foam applicator head, or the means for measuring temperature or pressure or other physical constants. Consequently, the equipment used in such processes includes facilities for the applying the aqueous compositions followed by means for removing the excess water from the treated substrate, such as squeeze rolls, extractors and driers.
spindle at rpm and had Brookfield viscosity of cps at 23 The number
Formulation contained percent of the same hydroxyethyl cellulose and had Brookfield viscosity of cps at 23 The average bubble diameter size in mm. Another suitable class of frothing agents is the group of sulfosuccinate ester salts, such as disodium Noctadecylsulfosuccinate, tetrasodium diamyl ester of sodium sulfosuccinic acid, and the like.
