Y. Sato et al., EFFECT OF CROSS-LINKING AGENTS ON WATER REPELLENCY OF COTTON FABRICS TREATED WITH FLUOROCARBON RESIN, Textile research journal, 64(6), 1994, pp. 316-320
Cotton fabrics and cellulose films treated with fluorocarbon resin (As
ahi Guard AG-480) with and without crosslinking agents (isocyanate blo
cked copolymer and aziridine) were washed and subsequently heat treate
d. Water repellency of the fabrics decreased with washing and recovere
d with heat treatment. The decreased water repellency with washing was
controlled by using the resin with a crosslinking agent. To investiga
te surface tension and surface chemical composition of the fabrics aft
er washing and subsequent heat treatment, the contact angle to water a
nd critical surface tension of the films were measured along with an E
SCA analysis of the fabrics. Adding cross-linking agents to the fluoro
carbon resin treatment controlled the decrease in F1s intensity and th
e increase in O1s intensity with subsequent washing.
