Definitions
- the invention relates to a process for refining keratin-free textile fiber material in textile treatment stages at pH values from 4 to 7, which contain no oxidizing chemicals.
- WO 00/68492 AI describes the use of a sodium salt of iminodisuccinic acid for washing raw wool in a pH-neutral medium.
- DE 197 35 796 AI relates to the finishing of generally keratin-containing substrates for protection against keratin pests using iminodibisuccinic acid as a setting agent.
- Another task for complexing agents is to remove heavy metal ions from native fibers and to mask them effectively in the treatment solution.
- iron, copper and manganese ions cause the spontaneous decomposition of hydrogen peroxide; in dyeing processes, such cations can interact with the dye Light absorption of this dye and thus also change the coloring result.
- copper ions in dyes for polyamide dyeing can shift the absorption maximum of the dyes and reduce the absorption itself.
- metal ions can change the reflectance values.
- NTA should be less problematic in well-working clarification stages due to its easy biodegradability, the detection in many drinking water reservoirs such as Lake Constance is an unsolved challenge. Studies on metabolites and maximum quantity restrictions as well as bans in individual countries show that NTA is also possible is a controversial chemical.
- NTA as a comparatively weak complexing agent, cannot be compared with today's standard products in many textile applications.
- phosphonates have become established here, which can be easily eliminated in sewage treatment plants, but are not biodegradable.
- DE 42 08 106 AI describes mixtures of citric acid and sodium gluconate, which act for all conceivable textile applications between pH values of 2 and 13 as a complexing agent, peroxide stabilizer or just as a buffer. Such mixtures work without the use of nitrogen-containing complexing agents, but the complexing effect of these hydroxycarboxylic acids becomes negligibly small, especially at elevated temperatures.
- EP 0 892 040 A2 examines aminocarboxylic acids, including iminodisuccinic acid (IDS), for cleaning hard surfaces and glasses, especially in mixtures with sorbitol or sodium gluconate.
- IDS iminodisuccinic acid
- WO 98/45251 describes the use of IDS in peroxide bleaching and prewashing of wood pulp in paper production, a higher degree of whiteness being achieved after subsequent bleaching.
- DE 100 04 893 AI describes a two-component system for achieving a “stone wash ⁇ effect. It mentions IDS for the production of a bright, little-colored dispersion "- in order to complex the heavy metal ions which may be used in the polymerization process and thereby increase the storage stability of the dispersion. In the examples, only EDTA is used. Complexing agents are only used for production and storage stabilization the dispersion used.
- GB-A-1 306 331 relates to a process for the preparation of IDS and mentions the potential utility of IDS and its derivatives for achieving uniform, light colors in the dyeing industry.
- EP 0 831 165 A2 describes a large number of possible uses for IDS, including generally an “enzymatic bleaching”. However, the methods disclosed each require an oxidizing agent or take place in highly alkaline or strongly acidic media.
- EP 0 831 165 A2 describes the use of, inter alia, IDS as a stabilizer in alkaline oxidative cotton bleaching with hydrogen peroxide, IDS always being used in combination with hydrogen peroxide.
- the object of the present invention was therefore to provide complexing agents for oxidant-free treatment stages in textile finishing, which have the disadvantages of Avoid prior art complexing agents known for this purpose. Improving the biodegradation behavior is a special requirement.
- the object is achieved according to the invention by a process for finishing textile fiber material in treatment stages free of oxidizing agents at pH values from 4 to 7, which is characterized in that iminodisuccinic acid or salts thereof are used as auxiliaries.
- Iminodisuccinic acid and its salts are also referred to as IDS for the purposes of the invention.
- the auxiliary preferably contains further complexing agents or dispersing agents such as, for example, hydroxycarboxylic acids, polyaspartic acids, acrylic acid homopolymers or acrylic acid copolymers.
- hydroxycarboxylic acids are citric acid or gluconic acid, since they have proven to be particularly suitable for the complexation ability of To increase IDS, especially with regard to calcium.
- Acrylic acid copolymers are preferably derivatives containing maleic acid or sugar.
- the weight ratio of IDS to the sum of further complexing agents or dispersing agents is particularly advantageously set at 1:10 to 10: 1.
- the auxiliary is used in an amount of 0.02 to 5% by weight, preferably 0.1 to 2.0% by weight, based on the weight of the goods. This ensures that a minimum complexing effect is achieved. At the same time, disadvantages associated with an excessively high proportion of IDS are avoided: If the complexation is too high, all hardness can be bound, which in some enzyme classes has a negative effect on their activity. In addition to the pure product costs, textile refiners also have to pay wastewater fees depending on the COD and BOD load. In addition, despite the fact that they are easily biodegradable, complexing agents such as NTA are found in drinking water reservoirs to a considerable extent. It is therefore preferable to use a small amount of each complexing agent and the smallest possible proportion as a blending component in product formulations.
- the textile treatment stage is preferably carried out at 20 to 130 ° C., which ensures optimum complex stability.
- Textiles are prewashed at pH values between 4 and 7, with enzymes often being added simultaneously for desizing, particularly in the case of woven goods.
- Complexing agents are also used here. After the subsequent peroxide bleaching, which is usually stabilized with phosphonate blends, the effect can be derived from the pre-cleaning stage via the desizing and whiteness level.
- Acrylic acid homo- and copolymers as well as biodegradable additives such as citric acid, polyaspartic acid and sugar acrylic acid copolymers improve both desizing and whiteness results.
- Amylases are preferably used as enzymes at pH 4 to 7 in desizing processes of woven goods; combinations with pectinases, proteases, lipases, hemicellulases and cellulases are also suitable for woven goods, whereas the same enzyme classes are used alone or in combination for knitted goods, but usually without the addition of amylases.
- the method according to the invention can also be carried out in such a way that the auxiliary is used together with enzymes. This is particularly important for enzymatic desizing. Desizing is simultaneously demineralized.
- the IDS-containing auxiliary of the process according to the invention has surprisingly proven to be particularly suitable, since it does not impair the effectiveness of the enzymes used, in particular of alpha-amylases, and also does not cause a higher sensitivity to temperature increases. These problems often prevent the use of complexing agents in the desizing step.
- Polyamide and polyester are dyed in an acidic environment. Heavy metals can interfere here because they form a complex with the dye, which can change its type non-specifically. Whether a complexing agent prevents this cannot be deduced from its complexing constants alone, but must be checked in a realistic system. Aids containing IDS surprisingly avoid the disadvantages mentioned in the process according to the invention.
- IDS can very effectively suppress heavy metal effects.
- mixtures are also well suited for this, so that the absolute amount of complexing agent with a high heavy metal binding constant is reduced.
- R3 acrylic acid polymer, 20% of the acid groups neutralized with sodium hydroxide solution, K value 25, 48% DM.
- R4 Commercial polyaspartic acid, adjusted to pH 10, 45%
- examples according to the invention are identified as B1 to B7, IDS-free comparative examples are identified as VB1 to VB4.
- Calcium binding value Determined by turbidity titration with light guide photometer at pH 11 in the presence of 2 g / l soda, at a start of 900 mV and a final value of 600 mV. Unit: mg calcium carbonate / g product.
- VB4 DTPMP, commercially available sodium salt as a 25% aqueous solution based on free acid.
- Application examples Application example 1: desizing and subsequent peroxide bleaching
- Starch-sized cotton weaves are impregnated at 60 ° C with 4 g / l of a commercial wetting agent, Kollasol ® MCE and a commercial amylase-containing enzyme preparation, Beisol ® T 2090, as well as 5 g / l of the complexing agents according to the invention, liquor absorption 100%. After 4 hours at 30 ° C is washed out at 90 ° C and dried.
- Example B4 shows that a mixture of IDS and polyaspartic acid also improved the degree of whiteness in comparison to pure IDS, especially if the. lower active substance content of example B4 taken into account.
- Example B2 shows that this effect is also achieved at a product pH of 7.
- Application example 2 polyamide dye solution with a copper-sensitive dye.
