| Résumé : |
Parasite and insect damage appear to be very significant causes for downgrading of bluestock,crust stock,or finished leathers.The purpose of this work was to produce a baseline for the most common causes of damage, which are pitting,grubs,mange,warts, and ringworm.This information was gathered and plotted for one year to see if seasonal changes had any bearing on the incidence of the defect.In this work we counted both 'healed' and 'open' defects as long as they were distinguishable.No attempt has been made to separate data of 'healed' verses 'open', or to quantify the percent of area involved in the defect.
This method incorporates a small amount of titanium dioxide on the bluestock to allow better visual inspection. |
