The cause of cockle defect in domestic sheepskins has been demonstrated. It is caused by keds (melophagus ovinus), which are blood-sucking parasites that live in the wool of sheep. The defect becomes apparent only after the wool is removed during processing. It appears as a scattering of dense nodules in the grain layer of sheepskins in a characteristic pattern of distribution. Affected sheepskin leathers can be seriously downgraded, depending on the severity of the defect. In addition, cockle reduces the physical strengh of both grain and suede leathers and increases their stiffness. Our earlier studies entailed special processing to expose the cockle nodules for easier counting. When subjected to certain process modifications, however, which were suggested by a cooperating tanner, sheepskins resulted that had lower apparent cockle counts and improved appearence. This paper describes certain process modifications which were found effective in attenuating some of the grosser defects in cockled sheepskins. |
