本實驗乃針對細丹尼聚酯織物以ICI dispersal Navy 5R-PC羧酸酯基型為底色染料，並經wet on wet及H.P.S.過程進行熱處理行鹼防拔染性及織物強力之影響。由實驗結果得知，以混合鹼劑經wet on wet及HPS的加工方式對拔染性之改善並不顯著。若有強鹼存在時，反而會使織物減量作用增大，造成強力下降，因此，經wet on wet及HPS流程行鹼防拔染加工時，以使用Na2CO3作為鹼拔染劑較佳。
The fine denier polyester fabric was printed by ICI dispersol Navy 5R-PC dyestuff and then using alkali agent for resist-discharge with wet on wet and H.P.S. processes, the effect of mixing ratio of alkali agent on resist-discharge and physical properties of fabric had been extensively studied. Based on experimental results, when strong base was used, the resis-dischargeablity and strength of fabrics decreased, and the reduction of weight of fabric increased with base. The Na2CO3 as agent for resist-discharge printing could obtain the effective results and keep good physical properties of fabrics.
