Definitions
- the present application relates to water repellents for textile finishing, a process for the hydrophobic finishing of textiles and the use of certain fatty substances as water repellents.
- hydrophobic finishing of textiles water repellents based on polysiloxanes, fluorocarbons or mixtures of aluminum or zirconium salts with paraffins are generally used (compare “Handbuch der Textilhilhilstoff”, A. Chwala, V. Anger, Verlag Chemie, New York 1977, Chapter 3.24 "Phobierstoff", page 735 ff).
- the hydrophobic finishing of textiles serves to make them either water-repellent or water-impermeable.
- the hydrophobizing agent is applied to the fibers of the textiles and is arranged there so that the hydrophobic parts of the molecule are perpendicular to the fiber surface. In this way, the tendency of the water to spread over the entire surface is greatly reduced.
- the water takes on the spherical shape due to the cohesive forces and pearls off the textile surface.
- hydrophobizing agents described in the prior art in particular the zirconium salt-containing paraffin emulsions, such as are described, for example, in DD-A1-218 564, enable sufficient hydrophobization of textile fabrics, there is the problem that such agents are not or not sufficiently biodegradable are.
- paraffin emulsions when such paraffin emulsions are applied via a padder, paraffin deposits are observed on the paddle rollers after a longer period of time, which make cleaning the rollers and thus a costly interruption of the production process necessary.
- hydrophobizing compositions which meet all the application requirements of the textile industry - in particular cause little or no deposits on the machine parts and at the same time are biodegradable.
- a hydrophobizing agent for textile finishing which contains a zirconium salt in combination with a fatty substance, which is selected from the group of a) branched or unbranched, symmetrical or asymmetrical dialkyl ether with a total of 8 to 44 carbon atoms and / or the b) esters of branched or unbranched C12-22 fatty acids with branched or unbranched C-8-22 fatty alcohols and / or c) branched or unbranched, symmetrical or unsymmetrical dialkyl ketones with a total of 8 to 44 C atoms.
- a fatty substance which is selected from the group of a) branched or unbranched, symmetrical or asymmetrical dialkyl ether with a total of 8 to 44 carbon atoms and / or the b) esters of branched or unbranched C12-22 fatty acids with branched or unbranched C-8-22 fatty alcohols and / or c) branched or unbranched,
- Zirconium acetate is particularly preferred.
- the fatty substances are known alkyl ethers of the general formula R 1 -0-R 2 , where R 1 and R 2 each represent alkyl radicals having 1 to 22 carbon atoms. The total number of carbon atoms in the molecule is 8 to 44. Both symmetrical ethers, ie R 1 and R 2 are identical, or unsymmetrical ethers (R 1 ⁇ R 2 ) can be used.
- the alkyl radicals R 1 and R 2 can be saturated, unsaturated, branched or unbranched. Those ethers whose radicals R 1 or R 2 have a C chain length of 10 to 22 are particularly preferred.
- the total carbon number of the ethers is preferably 20 to 44.
- Preferred ethers are, for example, dibehenyl ether, distearyl ether, dipalmityl ether or dimyristyl ether.
- An example of an asymmetrical ether is ethylhexyleicosyl ether.
- the ethers can be prepared by all known technical processes.
- esters of branched or unbranched C12-22 fatty acids with branched or unbranched C8-22 fatty alcohols are suitable.
- Suitable fatty acids are, for example, caprylic, pearlagon, capric, undecane, tridecane, myristic, pentadecane, palmitic, heptadecanoic, octadecanoic, nonanoic, arachic or behenic acid.
- Suitable fatty acids are, for example, caprylic, pearlagon, capric, undecane, tridecane, myristic, pentadecane, palmitic, heptadecanoic, octadecanoic, nonanoic, arachic or behenic acid.
- Fatty alcohols are, for example, capryl-caprin, lauryl, myristyl, palmityl, stearyl, arachidyl or Behenyl alcohol.
- the water repellents can contain dialkyl ketones of the formula R 3 -CO-R 4 with a total of 8 to 44 carbon atoms.
- alkyl methyl ketones such as octanonanon-2, nonanon-2, undecanon-2, dodecanon-2, tridecanon-2, tetradecanon-2, pentadecanon-2, heptadecanon-2, octadecanon-2, nonadecanon-2, pentadecanon-2, Heptadecanon-2, Octadecanon-2, Nonadecanon-2, Eicosanon-2 or Dodecasanon-2 can be used.
- Symmetrical ketones such as Undecanon-6, Tridecanon-7, Pentadecanon-8, Heptadecanon-9, Nonadecanon-10, Tricosanon-12, Hentriacontanon-16, Pentatricanon-18, Nonatricontanon-20 or Triatetracontanon-22 are also suitable.
- the ketones can be prepared by all methods known to those skilled in the art, for example by oxidation or dehydrogenation of secondary alcohols.
- the water repellents according to the invention are preferably in the form of an aqueous emulsion. Water is then contained in amounts between 10 and 90% by weight.
- the compositions preferably contain 30 to 80% by weight and in particular 40 to 60% by weight of water.
- the zirconium salts are generally present in amounts of 1 to 20% by weight, preferably in amounts of 5 to 15% by weight and in particular in amounts of 5 to 10% by weight.
- the fatty substances a) to c) are preferably present in the compositions in amounts of 10 to 95% by weight, in particular in amounts of 15 to 60% by weight and particularly preferably in amounts of 10 to 30% by weight.
- the agents can contain other suitable ingredients in addition to the salts and the fatty substances, in particular emulsifiers, but also anti-slip agents, wet fastness improvers, grip products, plasticizers, solvents, for example ethanol, n-propanol or i-propanol and pH regulators such as organic acids or bases.
- the pH of the aqueous emulsions is in the acidic range, preferably it is less than 4.5 and in particular it is in the range from 2.0 to 3.5.
- the auxiliary substances are present in minor amounts between 0.5 and 5% by weight. As a rule, the agents according to the invention contain such auxiliaries in total in amounts of at most 10 wt.
- the agents according to the invention are produced in a manner known per se by mixing the raw materials with water, heating them to temperatures between 40 and 90 ° C. and homogenizing them. Average particle sizes of less than 250 nm should be achieved. The average particle sizes are preferably in the range from 100 to 200 nm. After cooling, they can be used without further treatment.
- the agents are usually in the form of an aqueous emulsion Applied to the textiles with the help of a foulard.
- the agents according to the invention are suitable for the hydrophobic finishing of textiles made of synthetic or natural fibers, especially for cotton textiles.
- a process for the hydrophobic finishing of textiles is claimed, agents according to the above description being suitably applied to the textiles. Furthermore, the use of these agents for the hydrophobic finishing of textiles is claimed.
- Emulsifier 2.8% by weight
- the agents were prepared as follows: The raw materials were presented, heated to 85 ° C. and homogenized. The agents were then cooled to 20 ° C.
- the agents had pH values in the range from 2.8 to 3.0.
- the particle size was in the range from 200 to 250 nm.
- the Schopper test was carried out in accordance with DIN EN 20811: test fabric 100% CO (approx. 300 g / m 2 ), equipped with 150 g / l emulsion. Fleet intake 86%. Drying at 140 ° C.
- the friction resistance was tested with a continuous runner with 120 g / l liquor, 5 bar pressure and a speed of 20 m / minute.
- the friction resistance was interrupted when deposits on the paddle roller were recognizable:
