Definitions

• the invention relates to a method by which textile materials, in particular pile material, consisting of natural or synthetic fiber materials or mixtures of such fibers with one another, can both be dyed and finished in a continuous operation.
• the treatment of the textile materials e.g. with antistatic agents, leveling agents, anti-crease agents, water repellents and oil repellents, plasticizers, soil release agents and / or flame retardants.
• a process has become known from Textilveredlung 6 (1971), No. 11, pp. 708-711, according to which knitted textiles are dyed in a rotating drum in a fine-bubble, single-phase, aqueous foam which is formed by special, anionic and nonionic auxiliaries and which at the same time contains dyes or other chemicals for fixing them.
• This method was developed with the intention of being able to dye the material to be dyed in an extremely short liquor ratio, which results in low energy and water requirements and a relatively low wastewater load compared to other dyeing processes.
• the liquid fraction in the total volume of the foam is kept as small as possible.
• the contents of the drum are heated to the dye-fixing temperature with steam or hot air, the goods are treated for a certain time at this temperature, then cooled and spun.
• This method of operation is a discontinuous process which, due to the drum, is not suitable for piece goods, but only for finished articles.
• the textile material After the foam has been deposited on the textile material, the textile material is placed in a damper in which the applied foam layer is to disintegrate and the liquid in the foam lamellae passes over to the pile or fabric fibers and wets them and the dye is used for fixing on the Fiber receives the required temperature.
• the goods covered with the foam layer are usually passed through a channel in which there is a saturated water vapor atmosphere (100 ° C.).
• the foam formed serves the simultaneous application and the fine distribution of the foamed liquor on the goods. Once this has been done, the foamed condition of the fleet is no longer necessary and must be removed.
• the process of initiating foam disintegration by supplying foam-destroying agents can be complicated by the fact that rapid destruction of the foam is also effected at locations where the foam carrying the dye has not yet penetrated sufficiently deeply into the textile material. This can lead to irregularities in the coloring and may leave areas that are not colored.
• the sufficiently deep penetration of the color foam e.g. In the pole with higher pile goods is usually achieved by passing the goods after application of the foam layer over a vacuum gap, which pulls the applied foam into the pole just enough that after this process part of the foam is in the pole without however, to be pulled through the base fabric.
• This measure removes this foam portion from the direct mixing with the foam destruction agent applied.
• This can either mean that the defoaming within the pile does not take place quickly enough and the foam layer swells strongly in the damping process, or that the capillary adhesion of certain defoamers quickly causes the liquor between the fibers of the pile to fall through to the base fabric.
• the result is that only the pole tip and the pole base are colored.
• the process according to the invention succeeds in avoiding the disadvantages described and results in flawless dyeings and excellent finishing of the textile materials.
• the devices and machines required for the method according to the invention are known per se, as is the basic technology (cf., for example, Ch. Namboodri, R. Gregorijan, Continuous foam dyeing of carpets, Amer. Dyestuff Reporter, June 1978, pp. 27-34 ).
• polyether-siloxane copolymers allows the production of homogeneous dye and auxiliary liquors and their foaming without problems to form stable foams which do not disintegrate up to temperatures of 50 ° C. with the required or desired fineness of the foam bubbles.
• the foaming of the defoamer substances also allows the addition of the agents necessary for the equipment.
• Carpets loaded in this way have pressure points, grooves and an uneven pile (so-called walking streets).
• Furniture upholstery fabrics containing poles undergo similar changes in their surface properties, preferably in the most accessible and most heavily used areas. The result is a non-uniform appearance of the textile surface.
• the desired narrow particle size distribution which produces an optimal polarizing effect, can be achieved by uniformly and slowly adding the amount of silane used to the aqueous solution.
• colloidal dispersions of this type are systems which often suffer stability damage due to minor external influences such as salt additions, high mechanics, addition of cationic, anionic or nonionic surfactants and lose the useful properties mentioned.
• Suitable anionic surface-active agents for the preparation of the pole stabilizing agents are aliphatic and / or aromatic sulfonic acids, for example decyl, dodecyl, cetyl, stearyl, myristyl or oleyl sulfonic acids or their alkali metal salts. If cationic surfactants are used, it is advantageous to use halides and especially chlorides and bromides. Other surface active agents, including those from non-ionic, or at p hoterer nature can be used in conjunction with the above-mentioned means the same unless either due to their nature or quantity exert a disturbing influence on the stability of the colloidal suspension.
• a buffer that controls the pH value is of particular importance for the production of the pole stabilizing agents. Only the addition of the buffer substance causes such controlled hydrolysis, the alkoxysilanes, and subsequent condensation of the silanols formed therefrom that the claimed pole stabilization effect emerges.
• the colloidal suspensions can be produced at temperatures between room temperature and 80 ° C .; the temperature range between 50 and 70 ° C. is particularly preferred.
• the total concentration of surfactants is therefore approx. 1.5 - 4.5 g / l liquor.
• Example 1 (Production Example for a Defoamer According to the Invention)
• the mixture is then stirred for a further 5 hours at this temperature.
• the reaction mixture is then cooled to below 50 ° C. and the pressure is carefully reduced to 50 mbar.
• the low boilers contained in the reaction mixture are now heated to a bottom temperature of a maximum of 135 ° C. and a final vacuum of approximately 20 mbar.
• 15 kg of the acetoxysiloxane obtained are placed in a kettle together with 15 kg of toluene.
• a mixture of 18.8 kg of a butanol-started polyether with a molecular weight of 1820, an ethylene oxide content of 15% and a Propylene oxide content of 85%, the total ethylene oxide content obtained immediately following the starter molecule as a block unit, and 25 kg of toluene prepared and allowed to run into the mixture in about 15 minutes with vigorous stirring.
• 172 g of NH 3 are introduced over 45 minutes (325 l / h).
• the mixture is now heated to 80 ° C.
• 90 g of isopropanol are added to the reaction mixture and stirred for a further 3 hours at 80 ° C., during which time NH 3 is introduced until the reaction mixture is saturated.
• This foam is applied with a thickness of 10 mm on a pre-wetted PA carpet (velor, 600 g / m 2 ) by a foam applicator.
• the carpet goods covered by the foam are passed over a suction slit tube, the foam mat being partially sucked into the pile without loss of weight.
• the goods are passed through a chamber charged with saturated steam (approx. 100 ° C.), the foam disintegrating within 15 seconds.
• saturated steam approximately 100 ° C.

To determine the watering, 1 l foam was used immediately after production.
