Description

Characteristic oes known prior art It is known that in preparation solutions and emulsions for many microorganisms, such as Gram-negative and Gram-positive Bacteria, fungi, algae, in certain pH and temperature ranges good growth conditions exist. So multiply

in such preparation solutions or emulsions in the pH range between 5 and 9 and in

Temperature range between 15 and 45 ⁰ C, the vast majority of candidate microorganisms. On too Reason of their chemical composition and the fine distribution when applied in solution or Emulsion form they are a good breeding ground for microorganisms. This increased growth of microorganisms in Preparation solutions or emulsions can lead to such negative phenomena as odor nuisance, Decomposition and inefficiency of the preparation, blockage of the preparation cycles due to slime formation, health Endangering the operating personnel and others. Thus, for example, the partial or complete blockage of the piping leads to uneven application of the Preparation solution or emulsion, on the fibers, resulting in processing problems and frequent Cleaning cycles associated with lossy production interruptions leads. To prevent the germ growth and the associated adverse consequences are numerous biocidal agents such Aldehydes, peracids, quaternary ammonium compounds, amphoteric surfactants, alcohols, halogens, phenols, organometallic compounds Compounds and the like, as well as mixtures thereof have been proposed. The aldehydes, for example formaldehyde,

At the same time, during incorporation into fiber preparations, reactions with preparation components or Destabilization of preparation emulsions. In DE 2655539 and 2815400 it has been proposed the shelf life and handling of the preparation solutions

or emulsions thereby improve by hydrogen peroxide-releasing compounds, such as

Sodium perborate and succinic anhydride, or odorless or low odor not melting below 40 ° C Carboxylic acid anhydrides, which dissolve in water to low-odor carboxylic acids and hydrogen peroxide in low-odor

water-soluble percarboxylic acids with antimicrobial action are converted.

In DE 2701133 the antimicrobial effect is achieved by a mixture based on an aromatic acyloxycarboxylic acid

hydrogen peroxide releasing compounds when dissolved in water.

According to the teaching of DE 3046769, it is proposed to use salts of carrageenan acid as virocidal, bactericidal and fungicidal agents

However, these known methods have some disadvantages. They lead «. 3r training in preparation solutions

or emulsions are not in each case to the desired properties. Thus, they show in part a reduced biocidal activity or gaps in the presence of preparation components. Some of them have strong aggressive properties against pipe and tank material and also chemical pulp.

In DE 3615787 biocidal middle! suggested that from magnosum monoperoxyphthalate and a mixture of Tetraacetylethylenediamine, pentaacetylglucose and tetraacetylglucoluril exist. These possess for preparation solutions and

• Emulsions are not important, as the salts are not dissolved in the preparation film and thus lead to deposits on the thread-guiding organs.

Also mentioned in DE 3636541 aliphatic aldehydes, aliphatic alcohols and phenols, with surfactants

can not be used because they lead to damage to the polymer.

The cyclopropylmethyl ethers disclosed in DE 3305834 and those described in DE 2800739 Combinations of these compounds with 2-methyl-3-oxo-5-chlorothiazoline (1,2) or according to DE 3248507 with

i-Cyclopropyl-i-dihydro-1-oxoquinolinecarboxylic acid derivatives or bisuanide compounds mentioned in DE 3542516 have not been found to be suitable for reducing germ number in preparation solutions and emulsions.

Object of the invention

The aim of the invention is to further improve the biocidal properties of the pulp preparation solutions and emulsions, in particular the biocidal agents should act immediately germicidal, show a certain biocidal long-term effect, the emulsion stability promo r, i, the textile physical pulp parameters do not affect the quality-reducing, none Cause deposits on the thread guide organs and have no toxicity to warm-blooded animals.

Explanation of the essence of the invention

The invention has for its object to provide a biocide-containing pulp preparation mixture for synthetic high polymer threads, which has immediate germicidal properties and also over a longer period shows a biocidal effect, such known properties such as stability of the emulsion, positively influenced textile physical pulp characteristics, avoiding deposition and warm-blooded toxicity become. According to the invention the object is achieved by a pulp preparation mixture which consists of known components such as lubricants, emulsifiers, antistatic agents, thread closing agents, wetting agents, wear inhibitors and other additives or is characterized by the content of a Saccharinsulfonsulfobetains the formula I as a biocidal agent

These biocidal compounds based on the Saccharinsulfonsulfobetains of formula I are used in amounts between 0.3

and 0.5%, based on the total amount of preparation solution or emulsion, of known emulsifiers, lubricants,

Antistatics and other additives existing preparation mixture added and usable to a pH value

set between 5 and 9.

Levels of these compounds below 0.3%, based on the total amount of pulp preparations, are less

biocidal activity, while proportions of these compounds greater than 0.5% the effectiveness of the remaining

May affect Pfparation components. The compounds according to the invention of the indicated formula I are prepared by reacting saccharin

with sulfinic acids in the presence of formaldehyde.

The saccharin-sulfone-sulfobetaines of the formula I according to the invention impart the pulp preparations in Solution or emulsion form a very good biocidal efficacy, without having such indispensable properties

such as emulsion stability, textile-physical pulp characteristics and others negatively affected and depository phenomena on the thread-guiding organs become visible. This good biocidal efficacy is evident in the immediate germination already after a short time in the pH range between 5 and 9 at temperatures between 15 and 45 ⁰ C and in the associated instantaneous serviceability.

Other advantages are the biocidal long-term and depot effect against microorganisms such as bacteria, yeasts, fungi and their Compatibility with a chemically different exchange biocide. embodiments The invention will be explained in more detail below using an exemplary embodiment:

First, the microorganisms typical of synthetic chemical preparations, such as bacteria or yeasts and molds, are cultured in the pulp preparation mixtures to be tested according to known standard methods. These cultures are the biocidal agent according to the formula I.
