A Technical and Economic Appraisal of Yarn Package Dyeing

Abstract

A technical and economic appraisal has been made of dyeing a variety of yarns in package form. The philosophy of package dyeing has been discussed and package presentation has been considered. Future developments in the package dyehouse have been outlined together with possible processing routes. Although this study is concerned only with package dyeing, it is felt that some of the conclusions reached may, unfortunately, be equally valid for other sections of the UK dyeing and finishing industry. Greenfield studies have been undertaken, allowing for a number of processing options, from which detailed costings have been prepared. Based on these and taking current market conditions into consideration, the future of the yarn commission dyer seems uncertain. A greenfield dyehouse may only be feasible if it is used to service a yam production facility manufacturing high revenue products by modern techniques. Elimination of processes, especially winding, is essential.

The Package Dyeing of Wool Yarn — Process Appraisal and Product Assessment

“…Mr W Beal -Ciba-Geigy (ADP) Co. 1. Was there a significant difference in yarn loft or subsequent handle between yarns dyed in the very high flow Henriksen and the Pegg machines?…”

Has the SDC Journal catalysed changes in coloration technology?

“…It was also argued [73] that investment in modern equipment could be at least as successful in existing buildings. Two feasibility studies in the 1980s dealt with the establishment of yarn package dyehouses in greenfield sites either in the UK [74] or the USA [75]. There was a surprising degree of agreement between these two studies, both concluding that investment in a greenfield site was feasible for a new business but unlikely to be so for an existing operation due to poor market prices.…”
