The processing of Celon (nylon 6) woven fabrics on jigs is discussed, and comparisons are made with the dyeing and finishing of nylon 6.6. The use of covered jigs, with a steam‐injection device in the hood, is essential for satisfactory dyeings. Careful dye selection is important, since dyes are usually less fast to washing on nylon 6 than on nylon 6.6; greater use can be made of milling acid dyes than on nylon 6.6. Acetic acid should be used in place of formic acid, where possible, since the latter stiffens many nylon 6 fabrics. Aftertreatment is not always necessary, but where a full backtan aftertreatment is used the optimum temperature of treatment is 65d̀C. The preferred heat‐setting temperature is 185–195d̀C, i.e. 25‐15 degC lower than that for nylon 6.6.
