摘要:
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von Reserven oder Multicoloreffekten auf natürlichen oder synthetischen Polyamidfasermaterialien, welches dadurch gekennzeichnet ist, dass man vor oder nach der Behandlung des Textilmaterials mit einer Färbeflotte oder Druckpaste, welche mindestens einen anionischen Farbstoff enthält, nass-auf-nass entweder zwecks Herstellung von Reserven, eine flüssige Zubereitung lokal aufbringt, welche eine oder mehrere Verbindungen der Formel enthält, worin R 1 einen geradkettigen oder verzweigten C 10 - C 24 -Alkyl- oder Alkenylrest, R 2 und R 3 unabhängig voneinander C 1 -C 4 -Alkyl, und X den Rest eines Anions bedeutet, und der Benzolkern A weitersubstituiert sein kann, oder, zwecks Herstellung von Multicoloreffekten, eine oder mehrere flüssige Zubereitungen lokal aufbringt, welche neben einer oder mehrerer Verbindungen der Formel (1) zusätzlich mindestens einen anionischen Farbstoff enthält, und dass man zuletzt das Textilgut zwecks Farbstoffixierung einer Hitzebehandlung unterwirft. Nach dem erfindungsgemässen Verfahren werden hervorragende Reserven oder Multicoloreffekte erzielt.
摘要:
There is disclosed a process and a composition for dyeing polymeric fibers which have limited dye sites and/or difficult to penetrate chemical structures. Briefly stated, the process comprises the steps of contacting polymeric fibers with a dye composition comprising a disperse dye and a swelling agent. The fibers in contact with said dye composition are then preferably heated to a temperature and for a time sufficient to effect dispersion of a portion of said dye into said polymeric fibers. Subsequently, the fibers are treated to remove residual dye composition.

A liquid buffer composition comprises either or both of monsodium phosphate, in a concentration of 13-40 percent by weight, and tripotassium phosphate, in a concentration of 20-50 percent by weight, in aqueous solution. Combination of these two ingredients provides liquid buffer mixes for use in place of solid phosphate buffers.
摘要:
A process for preparing a foam composition having a coloring agent therein which is suitable for printing on a fabric. According to the invention, a foam growth inhibitor is added to a previously foamed composition having the coloring agent therein so as to restrict further foaming and substantially maintain the foamed composition at a desired blow ratio.

Embodiments of the present invention provide systems and methods for "dye-to-order" carpet manufacturing that address deficiencies in the carpet manufacturing industry, some of which are discussed above. In one embodiment, an improved manufacturing system is provided that allows manufacturers to change colors "on the fly" (e.g., within a single roll) with minimal waste. In another embodiment, a dye-to-order processing system is provided that maps multiple orders to undyed carpet rolls such that usage of the undyed carpet rolls is optimized.

Color, pattern, design, and/or the like is applied by means of a jet dye process, or any other secondary or post pattern application process, including but not exclusively, silk screen printing, rotary printing, etc., to a bonded carpet, where the yarn in the carpet is all white (no dye applied) or light colored or where the yarn is pre-dyed with a single or multiple colors or where the yarn is treated chemically. The bonded carpet preferably has a low face weight and flat, short, dense, vertical cut pile.
