A yarn core, either formed to a cylindrical shape, or in a cone configuration, includes a shallow cavity approximate one end, and within the cavity, around the circumference of the core, there is included a coating of a slip resistance material, preferably formed as a colloidal silica, to enhance the coefficient of friction at this location so as to temporarily adhere the yarn thereto either while it is being wound onto the core, or during unwinding as, for example, weaving proceeds from one depleted yarn core to a new core of yarn.
