The Role of Surface Tension on the Residual Water Content of Fabrics
|
ABSTRACT:
Cotton has been shown to hold up to 80% of its initial weight in water due to strong capillary forces after washing. According to the LaPlace equation for capillary rise, the rise is proportional to the surface tension of the air-liquid interface. The use of a tailored rinse additive has the potential to alter the surface tension of solutions significantly, thus leading to a lower capillary rise. This lower rise can be related to the residual water content in fabrics. The red...

Temperature Dependence of Blood Surface Tension
Physiological Research
; Summary Whole blood surface tension of 15 healthy subjects recorded by the ring method was investigated in the temperature range from 20 to 40 C. The surface tension σ as a function of temperature t (C) is described by an equation of linear regression as σ(t) = (-0.473 t + 70.105) 10^sup

Keeping Lung Surfactant Where It Belongs: Protein Regulation of Two-Dimensional Viscosity
Biophysical Journal
; ABSTRACT Lung surfactant causes the surface tension, γ, in the alveoli to drop to nearly zero on exhalation; in the upper airways γ is ~30 mN/m and constant. Hence, a surface tension gradient exists between alveoli and airways that should lead to surfactant flow out of the alveoli and
