Definitions

  • the invention relates to the use of C8-C22 fatty acid methyl esters as smoothing agents in lubricants for card spinning in a mixture with homopolymers and / or copolymers of esters of acrylic acid and / or methacrylic acid with intrinsic viscosities [eta] below 400 ml ⁇ g ⁇ 1 in amounts of 0.05 to 10 wt .-% - based on lubricant. Furthermore, the invention relates to a process for the smelting of textile fibers for the production of carded yarns.
  • Textile fibers that are processed into carded yarns are subjected to a carding process before spinning.
  • the textile fibers are subjected to very high mechanical loads.
  • the textile fibers are treated with a lubricant containing smoothing agents before carding.
  • Lubricants contain smoothing agents to prevent fiber damage and emulsifiers so that they can be applied as an emulsion, as well as other additives if necessary.
  • lubricants with hydrocarbons are used as smoothing agents. Since these smoothing agents are difficult to biodegrade, they are becoming more and more biodegradable smoothing agents for lubricants, for example by fatty acid esters, replaced (Textiltechnik International 1984 (8), 748-758).
  • Lubricants with isobutyl stearate or 2-ethylhexyl stearate as smoothing agents are biodegradable, but they have an unsatisfactory spreading capacity on the fiber and therefore no optimal fiber / fiber and fiber / metal friction during the production of carded yarn.

  • the amount of polymer is always based on the active substance content of the polymer in the emulsion if no other information has been given.
