Take a fabric and wound it up on a perforated beam; place the beam inside a closed chamber and pass the liquor containing dyes and accessory chemicals through the beam such that the liquor flows from inside to outside. In the process, it will penetrate …
process, and allowing time for the dyestuff to level throughout the wool mass. ... 2 Fast acid dyes Formic Acid 3 Acid milling dyes Acetic Acid 4 Supermilling dyes None 2:1 pre-metallised dyes for wool, silk and nylon would most probably be Class 3 or Class 4 acid dyes. Acid dyes have average to good colourfastness properties on wool.
These dyes have better fastness properties than levelling acid dyes, and have reasonable wet fastness, particularly if alkaline milling is to take place in a subsequent process. Super milling acid, or neutral dyeing, dyes are applied in a similar way to milling acid dyes, except that greater control over the strike rate of the dye is exercised.
Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a …
The process of attachment of the dye molecule to the fiber is one of absorption: that is the dye molecules concentrate on the fiber surface. There are four kinds of forces by which dye molecules ...

Textile Full Dyeing Process. Dyeing is the process of applying dyes or pigments to textile materials such as fibers, yarns, and fabrics in order to get a desired color and colourfastness. In dyeing, temperature and time management are two crucial elements. The textile dyeing process is recognized as one of the most environmentally unfriendly ...
Dyeing is the application of dyes lies on fibers, yarns, or fabrics to give them finishing of colors perfectly. This application also with pigments to achieving the color fastness and dyeing in textiles is a complete process of color transferred to finished clothing or a …
For dyeing with milling, supermilling acid dyes and 1:2 metal-complex dye, the recipe (% o.w.m.) is: x % dye. 0.5-1.5% Lyogen MF or SU liquid. 1-2% Imacol S liquid, 1-2 g/l sodium acetate and acetic acid for pH 4.5-7, depending on depth. The chemicals are added in the bath at 20-30ºC and then the dissolved dyes are added slowly or in installments.

Acid dyes are not transferred from bath to fiber below 39°C. Milling acid dyes have a minimum temperature of exhaustion at 60°C, but at 70°C, transfer of dye is fast. Super-milling dyes cause level dyeing only at boil. Mechanism of Dyeing with Acid Dyes: Dissolution of dyes in aqueous solvent, produces a colored anion,

Instead, the washing needs to be done in cool water through dry-cleaned/hand washed process. Milling Acid Dyes : Mainly used for self shading, wet fastness of these dyes is available in medium to high range. With some of these Milling Acid Dyes having bad …
Wet milling, also called wet media milling, is a process in which particles are dispersed in a liquid by shearing, by impact or crushing, or by attrition. A mill is charged with media (small beads or spheres) and activated by a high-speed agitator shaft to separate the individual particles. When the agitator rotates, it transmits kinetic energy ...

The combination of piezoelectric material and ball milling leads to new frontiers in catalysis research. Here we used piezoelectric BaTiO 3 nanoparticles as the additive for the degradation of dye pollutant in solid state in ball milling process. With the assistant of ppm level CuBr 2 and H 2 O 2, high degradation conversion (>99%) of dyes can be achieved in short time (10 min).
Isoindoline dyes of the general formula ##STR1## where R 1 is hydrogen, C 1-C 4-alkyl or benzyl and R 2 and R 3 independently of one another are each hydrogen, methyl, ethyl, methoxy, ethoxy, chlorine, bromine, fluorine, trifluoromethyl, methoxycarbonyl, ethoxycarbonyl or nitro, give pure brilliant deep yellow colorations with good lightfastness in surface coatings, printing inks and plastics.
