Leaño, Jr. Physical Description 1-8 graphs, tables Summary, Etc.      Crude aqueous extract of young coconut (Cocos nucifera) husk was used to dye fabrics made of Musa Textilis (Abaca), knitted cotton, Ananas comocus (pineapple), pineapple-silk, fine (21D) silk and coarse (360D) silk. Colorimetric evaluation revealed that generally alum lightens the color, while CuSO4 tends to darken it. The use of CuSO4/alum mordant system revealed the almost equal influence of each mordant in the resulting L values except in the case of fine silk and M. tectilis fabrics where the darkening effect of CuSO4 predominated. Incremental changes caused by varying the mordants were observed in the corresponding a and b values. Higher color strength, K/S values were obtained on fabrics using alum mordant compared to pure CuSO4 or their combination. Further, colorfastness to laundering (AATCC 61-2003) ratings are in the range of 3-4, although predominantly, the laudered samples all turned darker and qualifying the observed change not due to fading but to darkening. The corresponding staining ratings were in the range of 3.5-4.5 using multi-fiber No. 1. The colorfastness to perspiration (AATCC 15-2002) ratings were in the range of 3.5-4.5 with observed yellowing. The staining ratings were in the range of 3-4.5, but ratings of 2 were mostly on cotton mordanted with CuSO4. All the other ratings of the dyed fabrics comply with the minimum staining ratings specified by Oeko Tex 100. The use of CuSO4/alum mordant system further diversified the colorway of C. nucifera as it generally maintained the performance of the dye fabrics compared when using either 5% CuSO4 or 5% alum mordants.
