Abstract
The liquid repellency to liquids of varying surface tensions was examined for a number of differently woven cotton fabrics that were treated with a fluorochemical textile finish.
Expressions for the liquid-solid and liquid-air interfaces per unit of macroscopic surface area have been derived and used to calculate the apparent surface contact angles. Comparison with experimental data has shown that these expressions are correct.
Liquid-yarn advancing contact angles have been obtained from measurements of the pressure required to force the liquid through the pores in the fabrics.
The abrupt drop of repelling performance for liquids of surface tension under 25 dynes/cm. is discussed in terms of textile structure and fiber surface.
