Definitions

• these compounds aside from being capable of substantially reducing electrostatic charges, these compounds have the serious disadvantage that they cannot be directly applied to the fibers because of their high viscosity (about 200 centipoises/20 C.) and lack of wetting power and also because they are difficult to remove once they have been applied. Moreover, these compounds have a substantial adverse effect upon the angle of friction of the fibers treated therewith.
• compositions which have not only antistatic properties that are superior to those of the known condensation products between glycerol or polyglycol and ethylene oxide, but also are characterized by very low viscosity (120 130 centipoises/ 20 C.), emulsifiability with water and very high wetting power.
• these compositions can be readily removed therefrom. While applied, they do not change the angle of friction or flow of the treated material, as indicated by the electrometer in electrostatic tests.
• Example 1 -parts of a first condensation product-(obtained according to conventional methods) between ethylene oxide (mol ratio 5.4) and lauryl alcohol (mol ratio 1), and 35 parts polyglycol 200 (ethylene oxide condensate having an average M.W. of 200) are added to 40 parts of a second condensation product (produced according to usual methods) between ethylene oxide (mol ratio 8.36) and glycerol (mol ratio 1).
