Definitions

• This invention relates to the use of water-based lubricants for textile machines, in particular, the use as needle oils and/or sinker oils in textile knitting machines.
• Lubricants that must meet high requirements are used for lubricating textile knitting machines.
• the compositions of a needle oil or sinker oil should have a constant viscosity at different machine speeds and temperatures. In this case, the operating viscosity of the lubricant should lie in the range of ISO VG 15-ISO VG 100.
• the compositions of the needle or sinker oils moreover, should be resistant to aging.
• the lubricants are to be present in the form of a colorless and clear solution as possible. These colorless lubricants are to have a good-to-excellent scourability, i.e., washing out ability; in particular, it should be possible to scour the lubricants at low temperatures. When a lubricant can be scoured only incompletely, it results in problems in the subsequent treatments of knit fabrics. In particular, a uniform dyeing of the knit goods is no longer possible, and irreversible color defects are the result.
• the lubricants are also to have a long shelf life even at low temperatures without the formation of precipitates.
• the formation of precipitates can result in the clogging of the oil supply systems of the knitting machines.
• the lubricant also must not have a tendency toward phase separation over the overall service temperature range of 0° C. to 80° C.
• the phase separation of the lubricant can result in a deficient lubrication of the machine parts, and thus, can result in unevenness of the knit fabric, which also can result in defects in the knitwear in the subsequent color treatment.
• the lubricant In addition to good protection against wear and tear and erosion, the lubricant must also provide the lowest possible level of friction. This results in a considerable energy savings and in reducing the noise level, which in turn results in improving work conditions.
• the lubricant has to be slightly biodegradable, since the lubricant can get into the waste water via the scouring process and correspondingly has to be treated and decomposed via the clarification process.
• the textile oils that are used over time which are present in the form of an emulsion, in most cases are composed of more than 80% mineral oil, to which the usual wear-protecting and corrosion-protecting additives are added.
• emulsifiers are added to improve the scourability.
• anionic emulsifiers e.g., sulfonates
• nonionic emulsifiers e.g., fatty alcohol ethoxylates or else NPE
• cationic emulsifiers e.g., quaternary ammonium compounds
• the object of this invention is to prepare a liquid water-based lubricant for textile machines, with which the above-mentioned drawbacks, which develop when a mineral oil is used, are overcome, and which is present in the form of a solution.
• the lubricant can be used in textile machines, it should be biodegradable, and it should be scourable at the lowest possible temperatures as well as used in an overall service temperature range without phase separation, should offer good protection against wear and tear and corrosion, and should have as low a friction level as possible.
• a water-based lubricant for textile knitting machines which contains 5 to 50% by weight of water-soluble polymer and/or 5 to 50% by weight of emulsifier add water up to 100% by weight, is therefore used.
• the lubricant can also contain 0 to 15% by weight, in particular 2 to 5% by weight, of corrosion-reducing and protecting, respectively agent; 0 to 10% by weight, in particular 0.2 to 5% by weight, of wear-reducing and protecting, respectively agent; 0 to 1% by weight, in particular 0.01 to 0.75% by weight, of biocide; and 0 to 50% by weight, in particular 2 to 25% by weight, of an anti-icing agent.
• the water-soluble polymer that is contained in the lubricant is selected from the group that consists of polyalkylene glycols, in particular polyethylene glycol with molar masses of 1,000 to 35,000, water-soluble esters, polyacrylates, polymethacrylates, polyvinyl pyrrolidones, polyacrylamides, carboxymethyl cellulose, polyanionic cellulose, hydroxy cellulose, and hydroxyethyl cellulose.
• the emulsifier that is contained in the lubricant is selected from the group that consists of nonionic, anionic and cationic emulsifiers, in particular alkylene oxide polymers, sulfonates, carboxylic acid and dicarboxylic acid derivatives with a chain length of 6 to 16 carbon atoms, phosphate esters, and quaternary ammonium compounds.
• the corrosion-protecting and wear-protecting agent that is contained in the lubricant is selected from the group that consists of water-soluble phosphorus and/or sulfur compounds, and nitrogen compounds, the biocide is benzoic acid, and the anti-icing agent is selected from the group that consists of low-molecular glycols, in particular ethylene glycol, propylene glycol, trimethylene glycol, glycerol, salts or ionic liquids.
• the lubricant according to the invention can also be used in the form of a concentrate.
• the reduced goods traffic is advantageous, since the finished formulation can be produced directly by customers by dilution with water.
• the storage space that is required at the user site is reduced.
• the user can adjust the lubricant directly to the desired viscosity for its application.
• water is used as a carrier liquid.
• Special water-soluble additives such as polyalkylene glycol and/or water-soluble esters, are added to this carrier liquid, and then the corresponding operating viscosity is set between ISO VG 15-ISO VG 100.
• the lubricant has the following composition:
• Distilled water 68.0% by weight Water-soluble polymer, polyglycol 8000 S, Clariant 22.0% by weight Co. Alcohol polyalkylene glycol ether, Marlowet 5056, 5.0% by weight Sasol Co.

• an acetone-purified knitting needle (length 44 mm) is placed on a round filter (filter paper with a diameter of 55 mm, Whatman) and covered with 10 ml of aqueous textile oil. After 48 hours of storage at room temperature, the needle (black spots) and the filter paper (yellow-red coloring) are checked for corrosion.
• the study results shown in Table 1 can be summarized as follows.
• the lubricant that is produced according to the invention is a virtually colorless, limpid solution.
• the complete scourability is itself added without washing agents at low temperatures, which makes possible a considerable savings in energy.
• the friction level that is drastically reduced in comparison to the conventional needle oils allows one to expect a clearly improved energy efficiency as well as a lower noise level and extended holding times during operation.
• By the exchange of mineral oil or a basic oil corresponding to the latter by water a greater focus is placed on durability with the lubricant of this invention.
