1. Brief Introduction Liquid Sulphur Dyes is a kind of dyes widely using on the domestic
and international markets. On the bases of powder sulphur dyes, it
becomes pre-vat steadily liquor through scientific selecting
suitable materials and chemical processing. Compared with powder
sulphur dyes, it has many advantages, such as brilliant color,
excellent leveling, and simple operating, convenient using, stable
quality and unifying of coloring result. Low cost and brief
technology are also superior than vat and reactive dyes, and it is
suited for exhaust dyeing, jig dyeing, pad-steam and so on. It can
be used for dyeing for cotton, hemp fibroid textile and other
blending fiber with special requirements of good fastness. It can
achieve perfect putting color together because of complete and
bright color, and auxiliary form a complete set. And it doesn't
contain contraband, except of light green and bright green. In
order to extend the need of the client, making use of dye inter
mediates, our factory manufactured four liquid sulphur dyes: New
Red Brown Q-BRR, Red Q-LGF, New Blue Q-LBF and Navy Blue Q-SB. And
they get the favorable comment and pay close attention to of the
industry of printing and dyeing. We ardently welcome the factory of
printing and dyeing and agency to our company directing work,
discussing together, and closely co-operation. | 2. Cards Sample of Product: Specification 100% |
3. Applied Technology (Reference) | 1). A. Dip and Roll the Dye Liquor Reduction Steam Four Trough
Washing Oxidizing Soaping Washing with Hot Water Washing with Cold
Water Drying
B. Technological Parameter:
One dip one roll, the temperature of the roll liquor is 25℃-30℃;
The rate of roll liquor is 75%-85%;
Reduction steam is 102℃, time is 40"-60";
Speed of the machine is 35m-45m/min;
Four trough washing, flow;
Oxidizing, 30%double oxygen water,5-10g/L or choose other oxidant;
Soaping, the same as powder form;
Washing with hot water , above 85℃.
2). The quantify of using is decided by the depth of dyeing.
3) .The quantify of the antioxidant is inversely proportional to
the density of dyeing, light color should add more, dark add little
or add nothing, as follows: | Depth of Dyeing | Light Color | Mid-Color | Dark Color | Dyestuffs | 0-45 | 45-125 | 125-200 | Antioxidant | 40-30 | 30-20 | 20-0 |
| But the steady of the sulphur blue is not quite up to the mark, and
can be easy to oxidize, so when dyeing the bright blue, we should
add more antioxidant.
4). Oxidant Q-2: the using of oxidant is decided by the function of
the liquid sulphur dyes, some use, some don't use. But the
assortment not easily oxidized must be use Oxidant Q-2. After
oxidizing, its color will become beautiful and brilliant, and its
fastness also will get greatly improve. When using Oxidant Q-2, in
order to remove floating color, the colored fabric must be fully
washed, and its quantity of using is usually at 4-8g/L, and
temperature is 60℃ -70℃, and PH achieved 3.5-4 with glacial acetic
acid help, after oxidizing 10-15min., washing.
5). Technological Conditions:
Different varieties have different temperature, red brown is 40?C
-50?C, yellow, yellow brown and green are 60℃ -70℃, and black is
90.℃ |
