DIFFERENCE BETWEEN DYEING AND PRINTING


Dyeing

Mono color application
Dyes are applied in liquid form
Salt is needed
Temperature is used for better penetration during dyeing
Water plays an important role in dyeing
Percentage shade is calculated on the weight of material
Time is allowed for better penetration
Half bleached fabric is used for dyeing
The fabric is handled either in open width or in rope form
The fabric may be in wet/dry condition during dyeing
Uniform color application on both the faces of fabrics
Machinery requirement is comparatively simple (tanks, winches, jiggers, soft flow, padding mangle etc)
Cost of dyeing/meter is lower
The process of dyeing consumes more time
Dyeing consumes more water

Printing

Mono or multi color application
Dyes are applied in paste form
Salt is not needed
Temperature is not used during printing.
Thickening agent plays an important role
Percentage shade is calculated on the weight of paste
Time is not required since color is applied on the surface of the fabric only
Full-bleached fabric is used for printing
The fabric is handled only in open width form
The fabric is to be in dry condition only during printing
Due to single face printing, printed face will be darker and other face will be paler
Machine requirement is complex by way of design, screen preparation, printing machines and after process machineries
Cost of printing/meter is higher
The process of printing consumes short time
Printing consumes less water
