Abstract
Conditioning systems for polyester fibers consisting of from 40 - 60% by weight of a lubricating agent and from 60 to 40% by weight of an emulsifying mixture, the total conditioning system showing a loss by evaporation of less than 5% by weight at 220.degree. C within 1 hour, a viscosity of less than 200 cP (20.degree. C), and in dilution with water in the ratio of 2:1, 1:1 and 1:2, a viscosity of less than 150 cP, less than 500 cP and less than 250 cP (60.degree. C), respectively. These compositions are applied onto the fibers by known methods. They impart especially good sliding properties to the polyester fibers during texturizing.
