form. In the continuous filament industry, polyester or polyamide yarns are always dyed at package form, while viscose rayon yarns are partly dyed at hank form because of technology. The common dyeing process of cotton yarn with reactive dyes at package form is as follows: The raw yarn is wound on a spring tube to achieve a package suitable for dye penetration. These softened packages are loaded on a dyeing carrier's spindle one on another. The packages are pressed up to a desired height to achieve suitable density of packing. The carrier is loaded on the dyeing machine and the yarn is dyed. After dyeing, the packages are unloaded from the carrier into a trolley. Now the trolley is taken to hydro extractor where water is removed. The packages are hydro extracted to remove the maximum amount of water leaving the desired color into raw yarn. The packages are then dried to achieve the final dyed package. After this process, the dyed yarn packages are packed and delivered. Space dyeing Space dyeing is a technique of localized color application that produces a unique multicolored effect. History of garment dyeing Garment dyeing is the process of dyeing fully fashioned garments subsequent to manufacturing, as opposed to the conventional method of manufacturing garments from pre-dyed fabrics. Up until the mid-1970s the method was rarely used for commercial clothing production. It was used domestically, to overdye old, worn and faded clothes, and also by resellers of used or surplus military clothing. The first notable industrial use of the technique was made by Benetton, which garment dyed its Shetland wool knitwear. Complex garment dyeing In the mid-1970s the Bologna clothing designer Massimo Osti began experimenting with the garment dyeing technique. His experimentation over the next decade, led to the pioneering of not just the industrial use of traditional garment dyeing (dyeing simple cotton or wool garments) but, more importantly, the technique of “complex garment dyeing” which involved dyeing fully fashioned garments which had been constructed from multiple fabric or fiber types (e.g. a jacket made from both nylon and cotton, or linen, nylon and polyurethane coated cotton) in the same bath. Up until its development by Massimo Osti (for his clothing brand C.P. Company), this technique had never been successfully industrially applied in any context. The complexity lay in developing both a practical and chemical understanding of how each fabric responded differently to the
