Abstract
A fiber-treatment composition based on a microemulsion, having an average particle size not larger than 0.15 micrometers, of a carboxyl-modified organopolysiloxane having a degree of polymerization of form 350 to 2000 and having at least two carboxyl groups in each molecule is characterized by an excellent mechanical stability, dilution stability, and blending stability, and can impart a durable softness, smoothness, wrinkle resistance, and compression recovery to fibrous material without the occurrence of oil spotting. Further stability of the microemulsion can be realized by adding a basic material to the microemulsion to adjust the pH of the microemulsion, preferably to a value of from 6.5 to 9.0.
