Definitions
- the present invention relates to wetting agents which can be used in particular as mercerizing aids.
- Mercerization is a common step in the processing of cellulosic fiber materials and concerns the treatment of these materials in aqueous alkaline liquors.
- CH-A-192 832 describes e.g. Sulfuric acid esters of ethylene oxide adducts of aliphatic alcohols, which increase the wetting ability of the mercerizing liquors. According to CH-A-271 087, the wetting capacity of these liquors is increased by a mixture of alkyl sulfuric acids with certain alcohols and ethers. It is also known from DE-A-1 048 865 to use the sulfuric acid esters according to CH-A-192 832 in a mixture with a branched fatty alcohol as a wetting agent in the mercerization of cotton yarn.
- Wetting agents have now been found which, when used in mercerizing liquors, overcome the disadvantages mentioned and are notable for good wetting action and very little foaming.
- the wetting agents according to the invention always contain a C S- C 18 alcohol, for example 2-ethyl-n- hexanol, and optionally a hydrotopizing agent, for example 2,4-dihydroxy-2-methylpentane.
- the wetting agents known from BE-A-698 817 have an inadequate wetting action, which manifests itself in the relatively low shrinking speeds of the cotton.
- the present invention furthermore relates to the use of the wetting agents in the mercerization of cellulosic fiber materials and the mercerizing baths containing the wetting agents.
- component (a) in the wetting agents according to the invention there are sulfuric acid esters of fatty alcohols of the formula into consideration.
- the alkyl radical R 1 in this formula contains 8 or 9 carbon atoms and is derived from octyl or nonyl alcohol.
- sulfuric acid esters of branched isomers of the alcohols mentioned e.g. 2-ethylhexanol or trimethylhexanol.
- the sulfuric acid esters mentioned can be used alone or as a (technical) mixture with one another in the wetting agents according to the invention.
- the phosphoric acid esters of a monoalcohol used as component (b) can be used as monoesters of the formula or as a mixture of the esters of the formulas (2a) and (2b).
- the radicals R 2 contain 4 to 6 carbon atoms and are derived from butyl, amyl and hexyl alcohol.
- the phosphoric acid esters can be used alone or as a (technical) mixture with one another.
- Monobutyl phosphate is particularly suitable.
- component (c) hexanol, heptanol and octyl, nonyl and decyl alcohol, and also lauryl, myristyl, cetyl, stearyl and oleyl alcohol can also be used. These can also be used in the form of condensation products with paraformaldehyde [(CH 2 O) x ].
- Component (c), like components (a) and (b), can be used in the form of (technical) mixtures of the alcohols in question.
- Another component that can be used in combination with the components (a) to (d) mentioned (component (e)) is an adduct of one.
- Organopolysiloxane preferably dimethylpolysiloxane and ethylene or propylene oxide.
- Such adducts can by the likely formula are represented, in which q is 3 to 50, preferably 3 to 25, r 2 or 3, s 0 to 15, t 1 to 25, X1 3 to 10 and R 3 alkyl having 1 to 4 carbon atoms, preferably methyl.

- the wetting agents according to the invention are suitable as auxiliaries in finishing processes of cellulose-containing fiber materials. In particular, they prove to be valuable wetting agents in the mercerization of these fiber materials.
- 1-20 preferably 2.5-10 g of the above-mentioned aqueous solutions per liter of mercerizing liquor are used.
- Cellulose fibers for example, have a higher gloss during mercerization. At the same time, their dye absorption capacity and tear resistance are improved.
- the fibers are mixed with concentrated alkalis (approx. 22-28%), e.g. treated aqueous solutions of lithium, sodium or potassium hydroxide or mixtures of these hydroxides.
- concentrated alkalis approximately 22-28%
- the fibers can be subjected to simultaneous stretching, which further increases the gloss effect.
- the temperature of the mercerizing liquors is preferably about 5 to 20 ° C.
- the temperature of the mercerizing liquors is preferably about 5 to 20 ° C.
- the main cellulose-containing fiber materials are cotton and blended fabrics with regenerated celluloses such as Cell wool and rayon (rayon) in question.
- regenerated celluloses such as Cell wool and rayon (rayon) in question.
- the mercerization of blended fabrics made from native (e.g. cotton, as well as hemp and flax) and regenerated celluloses places high demands on the concentration and composition of the mercerizing liquors due to the divergent properties of these components. For this reason, mixed fabrics are almost exclusively dry mercerized, which prevents additional (critical) contact of the mixed fabrics with cooking or mesh baths.
- the mercerization is carried out as yarn or piece mercerization.
- a detailed description of these processes as well as the mercerization in general is e.g. in Lindner, Textile auxiliaries and washing raw materials,ticianliche Verlagsgesellschaft, Stuttgart, 1964, Volume 2, page 1474 ff.
- wetting agents according to the invention in particular soche, which contain components (a) to (5), also enable quick and trouble-free recovery of the alkali from the (mercerizing) washing baths following the mercerizing bath.
- soche which contain components (a) to (5)
- wetting agents according to the invention also enable quick and trouble-free recovery of the alkali from the (mercerizing) washing baths following the mercerizing bath.
- these wetting agents have an extremely low tendency to foam.
- the concentrated liquor obtained can then be reused in the mercerizing bath.
- the wetting agents according to the invention are thus at least on a par with the prior art with regard to their wetting action, but also had the great advantage that they e.g. with the lye recovery mentioned hardly tend to foam.
- a cotton strand (weight: 1 g, length 24 cm), weighted with a weight of 33 g, is immersed in the filled cylinder and then the change in length of the strand is measured at equidistant time intervals.
- the rate of shrinkage that can be determined from this is a measure of the effectiveness of the wetting agents used in the mercerizing liquor.
- This example shows the foam behavior of the mercerizing liquors in the application using the glass cylinder shake test.
- the wetting agent according to the invention completely suppresses foam formation.
- the foam development in the lye recovery is significantly reduced by the wetting agent according to the invention compared to the comparison wetting agent.
- This example shows the effectiveness of the wetting agents according to the invention in strongly alkaline mercerizing liquors.
- Desized cotton fabric (square meter weight 180 g) is attached to a pin frame without tension and immersed for 1 minute in a mercerizing liquor containing 311.9 g sodium hydroxide solution per liter (which corresponds to a 25% solution) and 6 g of a wetting agent from (a) 80 % of a 40% aqueous solution of 2-ethylhexyl sulfate (sodium salt), (b) 3% of a 50% aqueous solution of monobutyl phosphate, (c) 1.3% 2-ethyl-n-hexanol, (e) 0.5 % Siloconsurfactant L 546 "", (f) 3.5% sodium gluconate and (d) 11.7% 2,4-dihydroxy-2-methylpentane.
- the temperature of the mercerizing liquor is 18 ° C.
- the mixture is then leached with hot water (70 ° C.) for 1 minute and treated with cold water which contains 5 ml / l of acetic acid (40%).
- the fabric is then rinsed, squeezed off on a padder and dried in a drying cabinet at 100%. The gloss and the dyeability of the fabric are significantly improved.
