Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness. The packages are then dried to achieve the final dyed package.
Remove the tester from oven and allow the fabric to dry at room temperature. Frosting is the change of color caused by a localized flat abrasive action. Fabrics that have poor dye penetration possess poor colorfastness to frosting.

Dye penetration achieved during wet processing is a critical aspect of the dyeing application in the prevention of crease edge abrasion or ‘frosting’ that occurs during home laundering.
Garment dyeing: in garment dyeing, the garments are dyed by using undyed but ready for dyed fabrics. The dyeing's primary objective is to apply uniform color to the substrate (fiber, yarn, or fabric) with required color fastness. Tie-dye and printing are the methods where the color is applied in a localized manner.
The data for colorfastness to crocking showed that dyed fabrics possess excellent rubbing in dry with rating 4-5 however rubbing fastness are lower in wet state.
Retention and colorfastness of naturally dyed fabrics using a contact dyeing method. Literature review contact dyeing methods for contact dyeing, dyers apply natural dyestuff and mordant directly to fabric, then heat, soften or fermentate, dry, and launder the fabric to improve dye fastness and color development.
The crocking colorfastness is divided into dry crocking colorfastness and wet there are two reasons that the dye on the test fabric migrates to the fleece fabric.
The friction fastness of the dyed fabric is divided into dry friction fastness and wet friction fastness. Dry friction fastness is reflected in the dry cloth after the white cloth stains, wet friction fastness is reflected with the water content of 95% to 100% of the white cloth after the friction of the situation.
What is color fastness? color fastness is a term used in the textile industry to describe the resistance of a fabric against color fading or color transfer.

Dyeing is the crucial step in determining the colorfastness performance of a fabric. The structure of the dye, the amount of dye, its method of bonding to the fabric and dyeing procedures all contribute to a dye’s performance characteristics.
In these study, cotton fabric was dyed using reactive dyes using formaldehyde and non-formaldehyde dye-fixing agents.

Crocking is the tendency of a fabric to release colour when the surface is rubbed. For fabrics, crocking may occur when it has excess dye, or has been improperly dyed or coated (pfdp). The tests are made on both wet and dry fabrics, to determine the values achieved. It should be noted: deeper colours tend to perform worse than light colours.

When testing the rubbing fastness by means of the crockmeter, one differentiates between dry and wet rubbing fastness. In doing so, the fabric sample is rubbed against a white cotton fabric using a defined pressure. The rubbing fastness is also tested in wet condition because dyed textiles usually lose more color.
