Definitions
- the present invention relates to an improved process for the production of cellulose-containing textile materials by finishing with a crosslinking agent based on N-methylol ethers in the presence of a crosslinking catalyst based on magnesium chloride.
- non-iron textile materials can be obtained by the method according to the invention.
- crosslinkers are, for example, and the 1,3-bis (hydroxymethyl) -4,5-dihydroxyimidazolidinone-2, also referred to as 1,3-dimethyl-4,5-dihydroxyethylene urea ("DMDHEU”), and its derivatives with alcohols.
- DMDHEU 1,3-bis (hydroxymethyl) -4,5-dihydroxyimidazolidinone-2
- High-quality recipe is a catalyst.
- Magnesium chloride or mixtures of magnesium chloride with Lewis or Bronsted acids are used in many cases.
- Other catalysts such as zinc nitrate, zinc chloride or ammonium chloride are also common.
- other aids such as e.g. Plasticizers for use.
- the most important standard method is the dry cross-linking method.
- the textile material is impregnated with the finishing liquor, which contains the crosslinker (typical amount for pure cotton fabric: 40 - 45 g / 1) and the crosslinking catalyst (typical amount: 12 g / 1) and squeezed off, for example, with a foulard. It is then dried at higher temperatures and crosslinked (“condensed”) either in the same step or separately in a condensation apparatus. This is usually done at condensation temperatures of 150 to 190 ° C.
- the condensation time is usually 15 seconds to 4 minutes; the higher the condensation temperature chosen, the shorter the condensation time.
- the condensation conditions must be chosen so that the reaction proceeds as completely as possible, so it must not be “over-condensed” or "under-condensed”, otherwise there will be unacceptable losses in strength or insufficient easy-care effects with very high formaldehyde values.
- the wet crosslinking process has recently gained in importance, since so far only textiles, in particular cotton, with the highest finishing quality, i.e. with very high smoothness after washing and very good crease recovery with acceptable tear resistance losses, can be produced.
- a mineral acid (usually hydrochloric acid or sulfuric acid) serves as a catalyst in the wet crosslinking process, which may also contain salts.
- the textile is impregnated with this strongly acidic liquor, which can contain up to 150 g / l and more of crosslinking agent, and dried to a residual moisture content of 10 to 12% by weight.
- the mixture is then left at 30 to 35 ° C. for 20 to 24 h, the acid is neutralized and washed out. After drying, the usual tools for handle design are usually applied.
- the strongly acidic liquors with pH 1 or below can cause enormous losses in tear strength in the finished textiles
- R 1 represents a C 1 -C 8 alkyl group which may be interrupted by non-adjacent oxygen atoms and which may also carry one or more hydroxyl groups,
- R 2 denotes hydrogen, the group C ⁇ OR 1 or a -CC 8 -alkyl radical, which additionally carry hydroxyl groups and / or C ⁇ -C -alkoxy groups as substituents and is carried by non-adjacent oxygen atoms and / or C ⁇ -C -alkyl groups nitrogen atoms can be interrupted, and
- R 3 is hydrogen, a C ⁇ -C ⁇ o-alkyl radical, a C ⁇ -C ⁇ o alkoxy radical, which can be interrupted by non-adjacent oxygen atoms, or the group (-NR 2 -C ⁇ OR 1 ) means
- drying (b) and condensation (c) steps can be carried out separately or together, ie in one reaction apparatus by heating and simultaneously removing the water vapor.
- the principle of the process according to the invention can be applied both to woven fabrics and to knitted fabrics, the latter using the amounts of crosslinking agent and crosslinking catalyst to be reduced.
- the method according to the invention can also be transferred to other cellulose-containing materials.
- synthetic fibers such as polyester, it is of interest due to the fiber protection and energy saving.
- the amount of crosslinking agent and catalyst can be reduced because of the lower proportion of cellulosic fibers.
- Preferred amounts of crosslinking agent are 90 to 175 g / 1, in particular 110 to 160 g / 1 in the case of fabrics made of 100% cellulosic material, 40 to 70 g / 1, in particular 45 to 45 in the case of knitted fabrics made of 100% cellulosic material 60 g / 1, and in the case of mixtures of 30 to less than 100% by weight of cellulosic fibers and greater than 0 to 70% by weight of synthetic fibers, 45 to 120 g / 1, in particular 55 to 100 g / 1.
- the last-mentioned amounts of crosslinking agent are particularly suitable for polyester-cotton blends in weight percent of approximately 50:50.
- crosslinker For all of the information above and below, the amounts of crosslinker always relate to the corresponding solids content in g per liter of equipment liquor.
- the crosslinkers are usually used as aqueous solutions with a solids content of 30 to 80% by weight, in particular 50 to 75% by weight.
- N-methylol ethers I to be used as crosslinkers are, by conventional reaction, usually in aqueous solution, the corresponding N-methylol compounds of the general formula II
- the group R 1 is 0 alkyl group such as -CH 2 CH 2 OCH 3, -CH 2 CH 2 OCH 2 CH 3 or -CH 2 CH 2 OCH 2 CH 2 OCH 3 stands for an optionally interrupted by nonadjacent oxygen atoms C ⁇ -C ⁇ .
- R 1 include: n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, n-hexyl, 2-ethylhexyl and 2-methoxyethyl; of particular interest are the C ⁇ -C 3 alkyl groups ethyl, n-propyl, iso-propyl and especially methyl.
- alkyl groups and alkyl groups which are interrupted by oxygen atoms and which carry one, two, three or even more hydroxyl groups.
- the radical R 2 denotes hydrogen, the group CH 2 OR 1 and in particular a -CC 8 -alkyl radical, which also carry additional hydroxyl groups and / or -CC alkoxy groups as substituents and by non-adjacent oxygen atoms and / or by C ⁇ -C - Nitrogen atoms carrying alkyl groups can be interrupted.
- the radical R 3 is hydrogen, a C ⁇ -C ⁇ 0 alkyl radical, one
- C ⁇ -C ⁇ o-alkoxy radical which can be interrupted by non-adjacent oxygen atoms, and in particular the group (-NR 2 -CH 2 OR 1 ).
- N-methylol ethers I in which the radicals R 2 and R 3 are linked to form a five- or six-membered ring are particularly suitable for the process according to the invention.
- R 3 (-NR 2 -CHOR 1 )
- two such rings can also be condensed to form a bicyclic system via the C atoms of the radicals R 2 which are ⁇ -amide nitrogen.
- N-methylol ether I which can be used in the process according to the invention are:
- Amides of C ⁇ -C ⁇ carboxylic acids for example formic acid, acetic acid, propionic acid, butyric acid or valeric acid, which carry one or two CH 2 OR 1 groups on nitrogen,
- Carbamates with C ⁇ -C 10 alkyl groups in the ester radical which can be interrupted by non-adjacent oxygen atoms, for example methyl, ethyl, n-propyl, iso-propyl, 2-methoxyethyl or n-butyl, which have two CH 2 OR on nitrogen Carry 1 groups,
- radicals X are different or preferably the same and represent hydrogen, hydroxyl groups or C ⁇ -C alkoxy groups, for example methoxy or ethoxy,
- Y represents CH 2 , CHOH, C (CH 3 ) 2 , an O atom or an N atom bearing a C ⁇ -C alkyl group and Z denotes hydrogen or a C ⁇ -C alkoxy group, for example methoxy or ethoxy ,
- DMDHEU 1,3-dimethylol-4,5-dihydroxyethylene-urea
- one of the two methylol groups of the DMDHEU is etherified with a methyl radical, while the other methylol group, by reaction with a polyol, selected from the group comprising ethylene glycol, diethylene glycol, 1,2- and 1,3-propylene glycol, 1,2 -, 1,3- and 1,4-butylene-10 glycol, glycerol and polyethylene glycols of the formula HO (CH 2 CH 2 0) n H with 3 ⁇ n ⁇ 20, preferably diethylene glycol, is derivatized.
- asymmetrically substituted DMDHEU are described in WO-A 98/29393.
- the crosslinking catalyst is based on magnesium chloride as the sole component or as the main component.
- a finishing liquor is used which contains 10 to 40 g / 1, in particular 20 to 30 g / 1, of the crosslinking catalyst in the case of fabrics made of 100% cellulosic material, 5 to
- the finishing liquor containing the crosslinking agent and the crosslinking catalyst has a pH of 3 to 6.5, in particular 4 to 5.5, at (a).
- additives and auxiliaries customary in textile finishing can be used, for example amino-functional polysiloxane emulsions, dispersions of anoxidized polyethylene and nonionic wetting agents.
- the latter aids can, if necessary, significantly increase the quality of the equipment.
- the process according to the invention enables rapid and complete condensation of the crosslinking agent on the textile material at relatively low and therefore gentle temperatures. Normally, much longer condensation times are expected at the temperatures of step (c) of the process according to the invention.
- the condensation according to step (c) - depending on the respectively set temperature - usually takes place completely after 15 seconds to 4 minutes, in particular after 30 seconds to 3 minutes.
- the cellulose-containing textile material highly refined by the process according to the invention has very high smoothness notes and very good crease recovery with unexpectedly low tear strength losses and low formaldehyde values. Such results have so far only been obtained with the wet crosslinking process, but the formaldehyde values there are very high despite washing. In the dry crosslinking process, such a high amount of crosslinker as is used in the process according to the invention and in the wet crosslinking process usually leads to the destruction of the goods because of the occurring enormous loss of tensile strength.
