ABSTRACT:
An improved process of dyeing highly moisture absorbent cellulose containing textile materials having a ratio of filling to warp of between 77 to 23 and 50 to 50 in which such textile materials are woven from yarn having a range of twist multiplier of from about 2.25 to about 5.00 is provided in which water is applied to a first surface of the textile material to effectively moisten such surface. a liquid dye admixture is applied to a second surface, the second surface being opposite the first surface, in an amount sufficient to cover the second surface. The resulting textile material is then maintained in a holding zone for a period of time effective to allow the dyestuff constituent present in the liquid dye admixture to migrate through the textile material. Once the desired dyestuff migration has occurred, the dyed textile material is heated to a temperature of from about 300.degree. F to about 400.degree. F to fix the dyestuff and dry the dyed textile material. When desired, the dyed highly moisture absorbent cellulose containing textile materials can be cut into towels of predetermined sizes and over-edged to prevent fraying of the edges of the resulting towels.
