摘要：A process for the space dyeing of yarn (particularly yarn containing at least 10%of natural fibres) suitable for use in carpets, the manufacture of textiles and for handknitting, involves a series of nozzles across the path of a conveyor carrying transversehanks of yarn, applying sequential bands of colored dye along the transverse length ofthe yarn, passing the yarn through a first squeeze head to cause the dye formulation tospread on and penetrate into the yarn, fixing the dye, and passing the yarn betweenpressure rolls to remove sufficient of the moisture quickly so that no subsequent cross-staining of the yarn occurs. Successive pairs of pressure rolls are preferably used.
