Chromatex Dyeable PP for the Fiber and Textile Industry.

CENTEXBEL, Zwijnaarde and Elf-Atochem's Chromatex polymer additive provides good compatibility and dyeability in the polypropylene matrix. Chromatex can be added to the master batch during fiber extrusion. Resulting yarns and fibers are dyeable via select disperse dyes. Other applicable dyeing processes include exhaust dyeing and continuo..

Use of Proliposomes as an Auxiliary Product in Dyeing Processes for Wool and Polyester Fabrics.

The use of proliposomes as dyeing assistants for wool and polyester fabrics and their blends permits temperatures of 15 degrees centigrade lower than those required in conventional processes, the elimination of salt from dye baths, and a significant decrease in the quantity of contaminants in residual water. Proliposomes may be incorporat..

Dyeing Blends of Polyester and Wool with Liposomes.

Research on dyeing polyester and woolen fabrics and their blends focused on the use of liposomes as dyeing assistants in exhaut dyeing with disperse dyes. Objectives included optimization of dyeing conditions, particularly the concentration of liposomes and dye and the temperature, by the use of simulations; evaluation of the liposome in ..

The Dynamics of Low-Temperature Wool Dyeing: Effect of Ethyoxylated Compounds.

Researchers studied the effect of two series of ethoxylated compounds on C.I. Acid Blue 80 and the dynamics of wool dyeing at low temperature. The compounds were a fatty alcohol with 8, 11, 23 and 60 moles of ethylene oxide and a nonyl phenol with 10, 13, 15, 20, 30 and 40 moles of ethylene oxide. Results indicated that the dye bacame inc..

A New Trend in Silk Dyeing with Reactive and Azoic Dyes.

Researchers determined the optimal conditions for dyeing silk with reactive and azoic dyes and printing silk with azoic dyes. The experiment dyed mulberry and tussah silk fabrics and bleached cotton fabrics with reactive dyes. Tests measured dye uptake, lightfastness, and washfastness of the dyed fabrics. The two methods used to print azo..

Color Tone and Fastness of Chitosan Adhered Tussah Silk Fabric Dyed with Various Dyes.

Researchers investigated the effect of chitosan on the dyeing affinity, color difference, and colorfastness of chitosan adhered tussah silk fabric. Direct dyes increased dye affinity significantly. Acid, 1:1 metal comlex, disperse, basic, and reactive dyes increased dye affinity moderately. The metal complex dyes exhibited no effect on dy..

Dyeing Lyocell with Multi-Functional Reactive Dyes.

Lyocell offers much higher dyeability than conventional cullulosic fibers and requires special dyeing conditions. Interfibrillar crosslinking induced at the earliest possible moment prevents further fibrillation during the dyeing process. Some multifunctional reactive dyes, which have at least two reactive groups, form a covalent bond wit..

초음파와 자외선을 이용한 견의 저온염색

견직물은 다른 섬유직물에 비해 광택, 태, 드레이프성이 우수하여 오래도록 많은 사람의 관심을 끌어 왔으나, 높은 염색온도로 인해 섬유가 쉽게 손상을 받아 품질이 떨어지는 문제점이 있다. 따라서 염료의 고착을 증진시키기 위해 이용되는 산화환원 시스템의 경우에서와 같이 자유 라디칼을 생성하는 물질의 존재하에서의 견의 저온염색이 많은 주목을 받기도 했..
