This paper is to know the possibility of coloration of synthetic fibers with loess. Fabrics woven with polyester, nylon, and acrylic fibers were dyed by a dip-pad operation with a laboratory mangle. Drying, curing at 180$^{circ}C$ for 10 minutes and washing were followed. Effect of curing after drying were investigated in terms of K/S values and SEM microphotographes. Reddish-yellow(a:75.13, B:15.14, <TEX>${Delta}$<TEX>E:45.31) colored fabric ascertain possibility of coloration of synthetic fibers with loess. Acrylic fiber shows highest dye uptake of the three kinds of fibers and fastness increases by curing after drying.
