Carpet Rug Dyeing

We see so many colours, colour combinations and colour effects in the market place because colour is the most important component that the buying public looks for.

The following are dye methods that are commonly used in the manufacturing of todays carpets.

Pre Dyeing – this means that the fibers are dyed before the tufting process takes place.

 

Pre-Dyeing
Package Dyeing The yarn is wound onto perforated tubes called packages. The packages are then dyed by passing the dye through the packages under pressure and with heat.
Space Dyeing The majority of continuous filament nylon, level loop, commercial carpets are dyed in this fashion. This process uses a special dyeing machine that is capable of placing two or three different colours side by side on the same piece of yarn. This creates a random coloured or mottled effect.
Solution Dyeing This process creates the most colour fast carpet fibres. Solution dyeing can only be used on synthetic fibers because the colour is added when the fiber materials are in the liquid state.Polypropylene(olefin) is the only fiber that is exclusively dyed in this way. Small amounts of nylon fiber are dyed using this process with these numbers growing steadily. The main reason fot the increas is because of the stain resistance and cleanability this dyeing process gives
Stock Dyeing This is one of the first methods used to dye large batches of wool and synthetic staple fibers before they are spun into yarns.
Skein Dyeing Raw staple yarns are spun into single strands and then dyed. These single strands are called skeins. Once dyed the single strands are ready for plying into finished yarns.

 


Post Dyeing – this means that the undyed fibers were first tufted into a finished carpet and then dyed. This carpet in the undyed form does not have a secondary backing and is referred to as “griege goods”. Two of the most popular methods of post dyeing are the Beck and continuous process.

 

Post-Dyeing
Piece Dyeing – Beck or continuous In this method the finished carpet is dyed rather than the fiber. Hundreds of feet of carpet are either submerged into a largevat of dye(Beck) or the carpet is passed through a continuous dye range where the dye is applied by dripping or spraying.
Print Dyeing This dyeing process is very popular with bathroom or kitchen carpets. Pring dyeing is the direct application of dye to the top surface of the fiber after the carpet has been tufted. This is done by spraying or silk screening.
Cross Dyeing A method for obtaining a multi-coloured effect by using fibers of different affinities.
Stock Dyeing This is one of the first methods used to dye large batches of wool and synthetic staple fibers before they are spun into yarns.
Skein Dyeing Raw staple yarns are spun into single strands and then dyed. These single strands are called skeins. Once dyed the single strands are ready for plying into finished yarns.
