Foam dyeing for developing the wash-out effect on cotton knitted fabrics with pigment

摘要

In this study, the foam dyeing technology was applied to dye cotton knitted fabric for achieving the surface-dyed result. The T-shirt made by this surface-dyed fabric could easily obtain the wash-out effect after garment laundering. The pigment dyeing performances in foam dyeing were system studied. Colour strength, colourfastness and serviceability of fabrics dyed with the methods of foam-padding and liquid-padding were evaluated and compared. Results show that surface dyeing for cotton-knitted fabric with foam media could overcome the shortcoming of poor penetration in foam dyeing method, and turn the poor penetration into the superiority for obtaining the surface-dyed result. The serviceability such as water absorption and handle property was also well improved in foam dyeing method. Finally, the advantages of energy saving and reducing chemical usage were implemented throughout the dyeing process.
