Estimating the term…
The invention relates to the use of core-shell particles with a mean diameter of 10-300 nm and a standard deviation σ at least 10% of the mean value, and wherein the shell of the core-shell particle comprises a copolymer of vinyl aromatic monomer and maleimide monomer with a glass transition temperature Tg of between 120 and 220° C. for coating a yarn or fabric to inhibit or prevent wicking in said yarn or fabric. The invention further relates to an aramid fabric, such as boat sails, which yarns are provided with a finish comprising a diglycehde or a triglyceride obtained from glycerol that is esterified with saturated or unsaturated fatty acids with 6-20 carbon atoms and are then provided with the core-shell particles.
