Did you know? Carpet dye method can affect carpet performance and carpet stain resistance Types of carpet dyeing includes pre-dye, post dye, skein, stock dyeing , yarn dyeing, space dyeing, extrusion dyeing, beck dyeing, continuous dyeing, and print dyeing.Carpet Dye Methods
There are, essentially, two classifications of dyeing residential carpet
Post Dyeing – All carpet fiber that is to be post dyed is extruded as “white” fiber or fiber that is extruded without co With heavier products and with polyester fibers, beck dyeing is employed to dye the unbacked blanket also known as greige goods. With this method, the blanket is submerged in a dye bath and the temperature of the dye mixture is raised to open the dye sites of the fiber. The negatively charged dye molecules attach to the positively charged dye sites and the dye adheres to the fiber. This is the most expensive dye method, but is required to get good dye penetration on heavier products.
Continuous dyeing is a p
Print dyeing
is similar to continuous Pre-Dyeing refers to all dye methods in which the fiber is dyed before it is tufted into a blanket. While there are numerous methods of pre-dyeing, you should primarily be concerned with the most common method found in residential applications – solution dyeing.
Synthetic fibers begin as fiber pellets, very similar to the pellets found inside Beanie Baby® animals. These pellets are placed in a container, (post dyed) where color is only on the outer edges of the fiber. The advantage is that color, which permeates the fiber, is more difficult to remove as a result of bleaching agents, sunlight, and environmental pollutants. Contrary to popular belief, solution dy

lor pigment added (see solution dyeing – extrusion). This white fiber is spun, twisted, heat set and tufted into a blanket. After tufting the blanket, dyeing is performed, generally, in one of three fashions, beck dyeing, continuous dyeing and printing.
In products that have been beck-dyed, there may be an excess of dye left in the fabric after dyeing. In rare cases, when you walk across the finished pile with white socks, there may be some transfer to the socks. Also, when cleaning or extracting some of the dye may be found in the extracted rinse water. Neither of these instances should be cause for concern. The dyes are stable and the fiber is not losing color. The dye transfer is simply excess dyes that did not attach to fiber dye sites. This will occur more frequently in deeper shades such as navy blue, hunter green, or chocolate brown.
rocess in which the tufted blanket dyed on a continuous dye range. This dye method employs spray jets that continuously apply dye to the fiber as the carpet moves underneath. This method of dyeing can produce several hundred feet of dyed carpet per hour and significantly reduces the cost of carpet. The majority of residential carpet is dyed using this dye method. Following, dyeing synthetic latex and secondary backing are applied.
