Use of water-based lubricants for textile machines

Abstract

The present invention relates to water-based lubricants for textile machines, especially to such lubricants for use as needle oil and/or lifter oil as well as the use thereof as a needle oil and/or lifter oil.

1 . Use of a water-based lubricant that contains:
 at least one of 5 to 50% by weight of water-soluble polymer and 5 to 50% by weight of emulsifier,   add water up to with enough water to reach 100% by weight,   
       the lubricant having properties making it suitable for use as at least one of a needle oil and sinker oil in textile knitting machines. 
     
     
         2 . Use of a water-based lubricant according to  claim 1 , wherein the lubricant in addition contains
 0 to 5% by weight of a corrosion-reducing agent,   0 to 5% by weight of a wear-reducing agent,   0 to 1% by weight of biocide,   0 to 50% by weight of an anti-icing agent.   
     
     
         3 . Use of a water-based lubricant according to  claim 1 , whereby 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. 
     
     
         4 . Use of a water-based lubricant according to  claim 1 , whereby 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. 
     
     
         5 . Use of a water-based lubricant according to  claim 2 , whereby the corrosion- and wear-reducing agent that is contained in the lubricant is selected from the group that consists of water-soluble phosphorus and/or sulfur compounds, 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. 
     
     
         6 . Use of the lubricant according to  claim 1  in the form of a concentrate. 
     
     
         7 . Use of the lubricant according to  claim 2 , wherein the lubricant contains 2 to 5% by weight of said corrosion-reducing agent is provided and 0.2 to 5% by weight of a wear-reducing agent, 0.01 to 0.75% by weight of biocide, and 2 to 25% by weight, of an anti-icing agent. 
     
     
         8 . A water-based lubricant comprising:
 at least one of 5 to 50% by weight of water-soluble polymer and   5 to 50% by weight of emulsifier   up to 95% by weight of water   in a solution adapted for use as at least one of a needle oil and sinker oil in textile knitting machines.   
     
     
         9 . The water-based lubricant according to  claim 8 , wherein the lubricant in addition contains
 0 to 5% by weight of a corrosion-reducing agent,   0 to 5% by weight of a wear-reducing agent,   0 to 1% by weight of biocide,   0 to 50% by weight of an anti-icing agent.   
     
     
         10 . The water-based lubricant according to  claim 9 , wherein the lubricant contains 2 to 5% by weight of said corrosion-reducing agent is provided and 0.2 to 5% by weight of a wear-reducing agent, 0.01 to 0.75% by weight of biocide, and 2 to 25% by weight, of an anti-icing agent. 
     
     
         11 . The water-based lubricant according to  claim 1 , whereby 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. 
     
     
         12 . The water-based lubricant according to  claim 1 , whereby 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. 
     
     
         13 . The water-based lubricant according to  claim 10 , whereby the corrosion- and wear-reducing agent that is contained in the lubricant is selected from the group that consists of water-soluble phosphorus and/or sulfur compounds, 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.
