Abstract:
Cationic-dyeable carpet nylon is prepared by dyeing cationic-dyeable nylon fibers with acid or premetallized dye. The purpose of this process is to improve lightfastness and depth of shade and increase stain resistance so that the cationic-dyeable nylon is comparable to commercially available solution dyed nylon carpet. The figure is a graph plotted from the data of Table III of example 7 showing the premetallized acid dyeing of 12 samples of type 494 cationic dyeable nylon prior to heatsetting. It compares lightness/darkness (D/L) over the pH range of 2 to 10.
Abstract:
Stain-resistant nylon, especially cationic-dyeable carpet nylon, is prepared by dyeing cationic-dyeable nylon fibers with acid or premetalized dye. Lightfastness and depth of shade of an apparent value equal to acid dyeable nylons is obtained with superior stain resistance equal to commercially available solution dyed nylon carpeting.
Abstract:
Bi-constituent fiber having a cationic dyeable nylon, usually Type 6 nylon adequately sulfonated, as the major component with an intimate melt blent of a minor amount of a polyester are dyed with a anionic dye to improve lighfastness, ozone resistance and to provide resistance to acid-type stains. The fibers may be tufted into carpets that are resistant to acid-type stains. Both components of the bi-constituent fiber may come from recycled sources so that 100% of the fiber, excluding processing additives, is based on post consumer recycled polymer.
Abstract:
Multicolored stain-resistant nylon carpet is prepared by tufting a space dyed cationic-dyeable carpet nylon, dyed with an acid or premetallized dye intermixed and tufted with an acid dyeable nylon and overdyed with an acid dye to selectively dye the acid dyeable fibers but not the already space dyed yarns.
Abstract:
L'invention concerne la moquette à fils nylon, multicolore et résistante aux taches, fabriquée par un procédé de tufting sur un fil nylon prenant bien la teinture à agent cationique et teint par espacement, avec un colorant acide ou à complexes métallifères; ce fil multicolore est mélangé et tufté à un fil nylon prenant bien la teinture acide et surteint avec un colorant acide pour teindre de manière sélective les fibres prenant bien la teinture acide, mais pas les fils ayant déjà subi une teinture par espacement.
Abstract:
On prépare un nylon résistant aux tâches, tel que notamment un nylon pour tapis pouvant recevoir une teinture cationique, en teintant les fibres de ce nylon à teinture cationique avec un colorant acide ou prémétallisé. Des caractéristiques de stabilité à la lumière et d'intensité de la coloration d'une valeur apparente égale à des nylons à teinture acide sont obtenues avec une meilleure résistance aux tâches égale aux tapis de nylon teints par solution disponibles dans le commerce.
