Definitions
- the invention relates to agents for pretreating fibers containing iminodisuccinic acids, their salts and their mixtures with one another, which may have an additional content of citric acid, gluconic acid and / or magnesium in ionic form, for pretreating bleaching with H 2 O 2 .
- agents for pretreating fibers containing iminodisuccinic acids, their salts and their mixtures with one another which may have an additional content of citric acid, gluconic acid and / or magnesium in ionic form, for pretreating bleaching with H 2 O 2 .
- Such agents are used in aqueous solution.
- Textile-forming natural vegetable fibers such as cotton, sisal, jute and others and animal fibers such as silk and wool contain waxes, fats and in raw form other plant components that cause a yellowish-brown coloring of the fiber. This means that not all of the desired colors are possible; the colorations are also uneven.
- a pretreatment of these fibers is therefore carried out in bleaching and washing are combined. Such pretreatment can are applied to the fibers of the named origin, to those made from them Yarns and on fabrics, knitted fabrics or nonwovens of such fibers. This pretreatment can also be applied to mixtures of such fibers with synthetic Fibers and products made from them.
- So-called bleaching liquors which contain water, hydrogen peroxide, wetting / washing and emulsifying agents, alkali for adjusting the pH and H 2 O 2 regulators (bleaching regulators, stabilizers) are used to carry out the aforementioned combined pretreatment.
- water glass and inorganic phosphates have long been used as regulators.
- water glass (sodium silicate) as a bleach stabilizer, insoluble calcium silicate deposits appear on the machine and material, especially in connection with calcium salts. Because of the over-fertilization of the waste water, the inorganic phosphates were later replaced by (poly) -phosphonates.
- EDTA ethylenediamine-tetraacetic acid
- R 6 preferably stands for H, particularly preferably R 5 and R 6 stand for H.
- R 7 also stands for H.
- R 5 , R 6 and R 7 stand for H, so that (I ) represents the unsubstituted iminodisuccinic acid and its salts (both, iminodisuccinic acid and its salts, collectively referred to as IDS) of the type described above.
- R 1 , R 2 , R 3 and R 4 are more preferably replaced by R 11 , R 12 , R 13 and R 14 with the meaning of H, Na, K, NH 4 or H 3 NCH 2 CH 2 OH.
- the agents used according to the invention as bleach stabilizers, containing substances of the formula (I), are in pure form or are associated with small amounts of secondary components from the preparation of (I), such as maleic acid, fumaric acid, aspartic acid, malic acid, asparagine, tartaric acid, hydroxyaspartic acid, Condensates of aspartic acid etc. or their salts with the cations R 1 to R 4 indicated above.
- the secondary components are present in the mixture in an amount of at most 35% by weight, preferably 30% by weight and particularly preferably 25% by weight; the rest is 100% by weight (I).
- (I) is prepared by known processes in an aqueous medium, for example from maleic anhydride, maleic acid or epoxysuccinic acid and ammonia or aspartic acid. Methods of this kind are described in GB 1 306 331, SU 0 639 863, JP 6/329 607, JP 6/330 020 and DE 3 739 610.
- an alkali metal hydroxide or NH 3 can be added until a pH of 7.5 to 14 is reached.
- a broad pH range up to a strongly alkaline setting is in principle possible because alkali must be added to the bleaching liquor to which the agents according to the invention are added.
- a lower pH value has proven to be more favorable.
- sodium hydroxide is preferred as the alkali hydroxide, although in principle KOH or LiOH are also possible; it can be used both in solid form and in the easy-to-handle aqueous solution with, for example, 10 to 60% by weight.
- the invention further relates to the use of the above agents containing Iminodisuccinic acids and their salts of the formula (I), as bleach regulators and thus also a process for the pretreatment of natural textiles vegetable or animal fibers or their mixtures with synthetic fibers or of yarns, woven fabrics, knitted fabrics or nonwovens made from such fibers or their Bleaching in bleaching liquors containing water, alkali, hydrogen peroxide, Contain wetting agents, detergents and emulsifiers as well as bleach regulators is characterized in that agents of the type described above as bleach regulators be used.
- the pretreatment process can take a number of different forms are carried out, all of which are known to the person skilled in the art as prior art are: pretreatment in a long liquor (discontinuous or continuous); Block-cold retention process (KKV); Pad steam process; Pad roll process and other.
- Textile-forming natural vegetable fibers for example those made from cellulose, such as cotton, jute, linen or regenerated cellulose, as well as animal fibers, such as silk and wool, as well as their mixtures with synthetics can according to the invention be bleached.
- Vegetable fibers are particularly preferred preferably called cotton and mixtures thereof.
- synthetic mixed ingredients be synthetic polyamide, such as nylon or Perlon, polyester and Called polyacrylonitrile.
- bleaching liquors to be used according to the invention in addition to water, Alkali hydroxide, wetting, washing and emulsifying agents and agents according to the invention as bleaching regulators, hydrogen peroxide in an amount of 0.1 to 30 g / l used.
- the alkali hydroxide is added in an amount and added, that the stated pH of 7 to 14 is maintained in the bleaching liquor.
- Wetting agents, detergents and emulsifiers are those that are active in this field Are known to those skilled in the art.
- anionic, cationic or non-ionic surfactants are individual substances or mixtures from the known anionic, cationic or non-ionic surfactants; it is preferably anionic or nonionic surfactants, such as Fatty acids and their salts, fatty acid alkyl esters, fatty alcohols, glycerides, alkyl aromatic sulfonic acids, their polyglycol ethers and others known manner, these surfactants are chosen and compiled so that the unwanted accompanying substances of natural vegetable and animal fibers, such as fats, waxes and other plant components (e.g. remains of seed capsules etc.) and animal non-fibrous components are removed.
- water can demineralized water or a customarily provided service water, the has a different degree of hardness depending on the occurrence.
- the Agents serve as stabilizers for the hydrogen peroxide. The levy regulates the oxygen to bleach the fibers.
- the agent containing substances Formula (I) is used for complexing and "masking" alkaline earth metals, especially the disruptive Ca ions and heavy metals.
- Mg ions and Ca ions as an example of alkaline earth ions and Fe as an example of Heavy metal ions that are to be complexed are natural components of the usually available process water. Alkaline earth ions and heavy metal ions can also be used as impurities in the natural vegetable to be bleached Fibers are introduced. When using demineralized water is missing both the Ca to be complexed and the one desired as a co-stabilizer Mg, while those introduced by impurities in the natural vegetable fibers Components must still be considered. Mg ions can therefore in amounts of 0.1 to 1 g / l the bleaching regulators in addition to citric acid and / or Gluconic acid can be added. Taking these dependencies into account of the available water and the quality of the fiber to be bleached are known to the person skilled in the art.
- the agents according to the invention can also be used.
- Typical bleaching liquors were prepared with water at 0-20 °, ie as follows: long fleet KKV bleach PAD-Steam Magnesium sulfate g / l 0.2 0.2 0.3 Bleach regulator IDS g / l 1.0 4.0 4.0 Sodium hydroxide solution (32% by weight) ml / l 6.0 30.0 20.0 Hydrogen peroxide (35% by weight) ml / l 10.0 60.0 40.0
- the composition had a pH of 6.7.

- Sengen, Abbrennen der abstehenden Faserenden, um eine glatte Oberfläche zu erzielen. Dies ist üblicherweise der 1. Arbeitsgang.
- Abkochen, Beuchen, d.h. heiße Alkalibehandlung mit dem Ziel einer VorExtraktion der Faserbegleitsubstanzen bzw. Aufquellung der Fasern und der Samenschalen der Baumwolle. Dies wird meist vor dem Bleichen durchgeführt.
- Laugieren, Merzerisieren, Behandlung mit hoch konzentriertem Alkali mehr oder weniger unter Spannung des Materiales zur Erzielung einer starken Faserquellung und damit Glanz sowie Eliminierung der unreifen bzw. toten Baumwollanteile, welche sich nicht oder schlecht anfärben lassen. Dies kann vor oder nach dem Bleichen durchgeführt werden.
- Säure-Extraktion, wird vor dem Bleichen durchgeführt, wenn extrem hohe Mengen an Schwermetallen vorliegen (aus dem Brauchwasser und/oder dem Fasersubstrat). Die Komplexbildung des Bleichregulators wäre sonst überfordert.
- Ferner kommen zur Erzielung sehr hoher Weißgrade auch weitere Bleichverfahren
vor oder nach der Wasserstoffperoxid-Bleiche zur Anwendung,
beispielsweise
