An aqueous composition is used to clad yarn cores to provide unique coated yarns. This aqueous composition contains: (i) porous particles present in an amount of at least 2 weight % and up to and including 10 weight %, each porous particle comprising a continuous polymeric phase and discrete pores dispersed within the continuous polymeric phase, the porous particles having a mode particle size of 2-50 μm; (ii) a film-forming binder material having a T g of less than or equal to 25° C., that is present in an amount of 25-60 weight %; (iii) an inorganic filler material having a value of less than 5 on the MOHS scale of mineral hardness, in an amount of at least 2-15 weight %; and (iv) an aqueous medium in an amount of at least 35 weight % in which the film-forming binder material is soluble or dispersible. |
