Cotton print cloth was treated with aqueous Ca(OH)₂, MgCO₃, or <i>morpholine (110-91-8) to determine the ability of these compounds to reduce deterioration of the fabric during acceler-ated oven aging in dry and moist atmospheres at 100°. Only Ca(OH)₂ reduced strength loss during moist heating, and none of the compounds was effective during dry heating. Ca(OH)₂ also imparted alkaline reserve to the fabric, whereas MgCO₃, because of its low solubility in H₂O, could not be deposited in sufficient amount to be effective. All three compounds, and especially morphoiine, caused yellowing. Exposure to morpholine also accelerated loss in strength of the fabnc. These experiments were performed as part of the studies to examine possible methods for conserving historical textiles. -- AATA
