a 100 goosedown sample, treated with a hydrophobic silica pigment water-repellent finish was compared to an untreated 100 goosedown sample to determine the effect of the treatment on the amount of water absorbed by the down, and the properties of the down when wet the silica pigment markedly reduces the amount of water absorbed by the down, thus reducing its heat loss when wet. the finish remains effective after laundering, and there appear to be no changes in the mechanical properties of the down due to the finish. the effectiveness of the finish was further assessed when treated and untreated wool/nylon socks were tested for amount of water absorbed the untreated socks absorbed appreciably more water than did the treated socks
