BQ International is a leading Supplier & Exporters in Brazil, Vietnam, and Indonesia. Reactive dyes are a class of highly coloured organic substances, primarily used for tinting textiles that attach themselves to their substrates by a chemical reaction that forms a covalent bond between the molecule of dye and that of the fibre. The dyestuff thus becomes a part of the fibre and is much less likely to be removed by washing than are dyestuffs that adhere by adsorption.
The first fibre reactive dyes were designed for cellulose fibres, and they are still used mostly in this way. There are also commercially available fibre reactive dyes for protein and polyamide fibres. In theory, fibre reactive dyes have been developed for other fibres, but these are not yet practical commercially. The dyes contain a reactive group that, when applied to a fibre in a weakly alkaline dye bath, form a chemical bond with the fibre. Reactive dyes can also be used to dye wool and nylon, in the latter case they are applied under weakly acidic conditions.
The most important characteristic of reactive dyes is the formation of covalent bonds with the substrate to be coloured, i.e. the dye forms a chemical bond with cellulose, which is the main component of cotton fibers.
Fiber reactive dyes are the most permanent of all dye types. Unlike other dyes, it actually forms a covalent bond with the cellulose or protein molecule. Once the bond is formed, what you have is one molecule, as the dye molecule has become an actual part of the cellulose fibres molecule. No wonder you can safely wash a garment that has been dyed in bright fiber reactive colours with white clothing, a hundred times, without endangering the whites in the least - even if it is all different bright colours, or even solid black! In contrast to all other dyes the reactive dyes bind chemically to the textile fibres, significantly improving the product's colour stability and washability. Thus reactive dying of cotton is currently the most widespread textile dying process in the world.

FOOD COLOUR
> Food Colours

> D & C Colours
The colour of food is an integral part of our culture and enjoyment of life. Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow colour to various foods. Butter has been coloured yellow as far back as the 1300's.
We provide Food Dye. Today, all food colour additives are carefully regulated by authorities to ensure that foods are safe to eat and accurately labelled.
WHY ARE COLOUR ADDITIVES USED IN FOODS?
Colour is an important property of foods that adds to our enjoyment of eating. Nature teaches is early to expect certain colours in certain foods, and our future acceptance of foods is highly dependent on meeting these expectations.
Colour variation in foods throughout the seasons and the effects of food processing and storage often require that manufacturers add colour to certain foods to meet consumer expectations. The primary reasons of adding colours to foods include:
» To offset colour loss due to exposure to light, air, extremes of temperature, moisture and storage conditions.
» To correct natural variations in colour. Off-coloured foods are often incorrectly associated with inferior quality. For example, some tree-ripened oranges are often sprayed with Citrus Red No.2 to correct the natural orangy-brown or mottled green colour of their peels (Masking inferior quality, however, is an unacceptable use of colours.)
» To enhance colours that occur naturally but at levels weaker than those usually associated with a given food.
» To provide a colourful identity to foods that would otherwise be virtually colourless. Red colours provide a pleasant identity to strawberry ice while lime sherbet is known by its bright green colour.
» To provide a colourful appearance to certain "fun foods." Many candies and holiday treats are coloured to create a festive appearance.
» To protect flavours and vitamins that may be affected by sunlight during storage.
» To provide an appealing variety of wholesome and nutritious foods that meet consumers' demands.

Direct Dyes:
DIRECT DYES
>Sunfast & Non Benzedine Direct Dyes
>Non Benzidine Direct Dyes
Direct dyes are another class of dyes, one of the two types of dyes that are mixed in 'all purpose' dyes such as Rit. (The other type in the mixture is an acid dye, which will not stay in any cellulose fiber for long.) The colours of direct dyes are duller than those provided by fiber reactive dyes, and the washfastness is poor - expect anything dyed with them to 'bleed' forever. The one advantage is that direct dyes may be more lightfast, that is, resistant to fading in the light, than fiber reactive dyes. The "direct dye" classification in the Colour Index system refers to various planar, highly conjugated molecular structures that also contain one or more anionic sulfonate group. It is because of these sulfonate groups that the molecules are soluble in water. Though most direct dyes still can be obtained in powder form, it is increasingly popular to receive them as liquid concentrates. The advantage of concentrates is that they are easy to handle and meter. The disadvantage is that the surfactants and co-solvents needed to keep the dye concentrates stable may interfere with retention and sizing in the case of very deeply coloured grades.
Direct dyes are used on cellulose fibers such as cotton, rayon, and linen. They lack the permanence of the cold water fiber reactive dyes which most serious dyers prefer for use on cellulose fibers, but in some cases they have advantages that make their use worthwhile. For example, while many of the direct dyes are not very lightfast, there are some dyes in the class that may be more lightfast than similar shades of fiber reactive dyes. All direct dyes perform rather poorly with respect to washfastness. Without an appropriate after-treatment, direct dyes bleed a little with every washing, losing their brightness and endangering other clothes washed in the same load. However, there are special after-treatments which may be used to solve this problem. (Vinegar is not among them! In spite of claims you may see to the contrary, you cannot use vinegar to set any dye on cotton or other cellulose materials.) A product called Retayne, which is an ionic bulking agent which essentially "glues" the dye into the fiber, works very well to make fabric dyed with direct dyes washable without bleeding of the dye.
The name 'direct dye' alludes to the fact that these dyes do not require any form of 'fixing'. They are almost always azo dyes, with some similarities to acid dyes. They also have sulphonate functionality, but in this case, it is only to improve solubility, as the negative charges on dye and fibre will repel each other. Their flat shape and their length enable them to lie along-side cellulose fibres and maximize the Van-der-Waals, dipole and hydrogen bonds. Below is a diagram of a typical direct dye. Note that the sulphonate groups are spread evenly along the molecule on the opposite side to the hydrogen bonding -OH groups, to minimize any repulsive effects.

Acid Dyes:
ACID DYES
Bq Internationaol is a Leading Acid dyes Supplier & Exporters in Most of Countries. Acid dyes are water soluble anionic dyes that are applied to fibres such as silk, wool, nylon and modified acrylic fibres from neutral to acid dye baths. Attachment to the fibre is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fibre. Water soluble Acid dyes are not substantive to cellulosic fibres. Acid dyes are used both commercially and by the studio dyer to dye protein/animal fibers such as wool, silk, mohair, angora, alpaca and some nylons and synthetics. Acid dyes require the use of an acid such as vinegar, acetic or sulphuric acid to set the colour.
Acid dyes sound scary to some novices, who imagine that the dyes themselves are caustic strong acids. In fact, the dyes are non-caustic, are in many cases non-toxic, and are named for the mild acid (such as vinegar) used in the dyeing process, and for the types of bonds they form to the fiber. Some of them are significantly more toxic than fiber reactive dyes, while others are even safe enough to eat, and are sold as food colouring.
ACID DYES FALL INTO SEVERAL CLASSES
1. Levelling acid or strong acid dye,
2. Milling or weak acid dyes, and
3. Super milling or fast acid or neutral acid dyes.
They are also the acid dye component of all-purpose or union dyes such as Rit and Tintex, says Knutson. It's difficult now to find out which specific acid dyes fall into which of these dye classes, however. At least part of the reason is that the information is not particularly useful to the dyer.
Most histologic dyes are classified either as acid or as basic dyes. An acid dye exists as an anion (negatively charged) in solution, while a basic dye exists as a cation (positive charge). For instance, in the hematoxylin-eosin stain (H&E), the hematoxylin-metal complex acts as a basic dye. The eosin acts as an acid dye. A very large class of dyes containing acidic groups, such as the sodium salts of sulfonic acids or phenolic groups. They are more soluble and have less tinctorial value than basic dyes but they also have greater light fastness. They do not form lakes with tannin. Acid dyes are used in dyeing leather, paper, etc., and their particular value lies in their ability to produce brighter, more uniform colours. They are normally applied from an acid dye liquor (acetic, formic, or sulphuric acid); however, unless applied from a neutral or only slightly acid dyebath, i.e., pH of 6.0 to 7.0, their use is likely to result in acid degradation of the material dyed.

Solvent Dyes:
SOLVENT DYES
Our dyes are solvent soluble dyes of high quality for wide use in inks and coating industries. Ensuring superior solubility in organic solvent systems, these solvent dyes are applied as dispersion in a water bath. The dye is commonly known as disperse dye have wide application for coloration of polyester fibers. In contrast to ordinary dyes, our solvent dyes are pure in nature and contain low amount of impurities. Catering to the special needs of plastics coloration, these dyes can withstand over 350°C of temperature during extrusion and injection moulding process. The dyes are best for colouring a variety of solid materials, such as nylon, polyester, acetates, PVC, acrylics, PMMA, polystyrene, PETP and styrene monomers.
WHAT ARE SOLVENT DYES?
A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, & other hydrocarbon-based nonpolar materials. Fuel dyes are one use of solvent dyes. Their molecules are typically nonpolar or little polar, and they do not undergo ionization. They are insoluble in water.
Names of solvent dyes are often generic, of the scheme "solvent ", eg. Solvent Red 24, Solvent Red 26, Solvent Red 164, Solvent Yellow 124, Solvent Blue 35, etc.
Red and yellow solvent dyes are often azo dyes, green and blue ones tend to be anthraquinone dyes.
WATER SOLUBLE DYES/SOLVENT GREEN 7
Water soluble dye is dissolved in water directly without any mediums, and it can keep water clean, transparent, without any impurities and precipitates, in the meantime, it is fluorescent dye. Solvent Green 7 is one of water soluble dyes, it is widely used in fluorescent inks, fluorescent marker pen, aqueous ink, hand sanitizer, shampoo, soap, antifreeze, cutting fluid, water chest, aqueous materials, greases, lubricating oil, cosmetics, trace dye of water quality sysytem, trace dye of boiler system.
OIL SOLUBLE DYES
is also called oil dye, oil-based dye or solvent based dyes. One type of non-polar organic solvents that is commonly used with oil dyes is petrol. Accordingly, oil solvent dyes are often used in the automotive industry to color petrol fuel and other hydrocarbon based fuel oils. Oil can be colored by oil soluble dyes.In addition, many solvent dyes are used as components by the biological stain manufacturing community to produce stains that will identify various cell structure components in medical diagnostics and scientific research.
Oil soluble solvent dyes have better temperature stability in engineering plastics, very high brightness and do result in completely transparent plastics without any haze and light scattering. Processing is easy and process parameters like viscosity remain unaffected. Process conditions for engineering plastics like polystyrene, ABS, PC, PMMA, PA and others are quite severe. During extrusion and injection moulding of PC the dyes have to withstand temperatures up to over 350°C for some minutes. Only selected oil solvent dyes do show the needed chemical resistance. Chemical stability also leads to long lasting final products which have to withstand sunlight and weather. As an example red car taillights will last as long as the car itself without loosing the bright red colour. To achieve this, the right transparent polymers and right dyes have to be taken.
Commodity polymers like Polyethylene, polypropylene, plasticized PVC or rubber are soft at low temperatures. we do not recommend any solvent dyes for coloration of these polymers but pigments have to be used.
Besides plastics industry, a major application for solvent dyes is printing or solvent based writing ink. Furthermore, oil soluble dyes are widely used in rubbers, oil inks, spinning, waxes, smoke, paints, color paste, transfer printing, marking pens, ball point pens, candles, oil, fats, solvents, bitumen, lubricants, marking inks, inkjet printing inks, dye sublimation printing, glass coloration, signaling smoke, firework and in the pyrotechnics industries, gold imitation, other transparent metallic effects of metallized polyester films, other hydrocarbon-based nonpolar materials.
NIGROSIN BLACK
Nigrosin Blacks include oil soluble nigrosine (color index solvent black 7), spirit soluble nigrosine or alcohol soluble nigrosine (color index solvent black 5), MS conc nigrosine (color index acid black 2) and aniline black (color index pigment black 1). All Nigrosins do show absorption in the infrared light making them suitable for optical character recognition. They are suitable for inkjet inks, ball point pen inks, solvent marker pen inks, water sign pen inks, industrial inks, ribbon inks, carbon paper, shoe polish, plastics, phenolic resin, polyamide resin, urea resin, lacquers, varnishes, wood stains, leather, cotton, flax, metallic products, coatings, alcohol based oil soluble self drying alkyd coatings, nitryl paints, water based coatings, thermosetting coatings, stationery commodities, alcohol based printing ink, plastics application such as acrylic resin, unsaturated polyester resin, fibrin resin, bakelite, polyester alkyd, polyvinyl chloride, polycarbonate,polystyrene, polypropylene, non-water soluble coloring of leather and fur, coatings, printing ink, positive charge conrol agent in electrostatic printing powder, coloring for stationery.
METAL-COMPLEX SOLVENT DYES
Metal-complex solvent dye is shorted as metal-complex dyes, these are mainly anionic chromium and cobalt complexes of azo dyes. The cation is either a sodium ion or a substituted ammonium ion. These dyes are normally soluble in alcohols, glycolethers, ketones and esters. Solvent dyes of metal complex have a higher colour strength and a higher light stability, because metal particles go into the dyes' molecule.
Wood stain or wood coating is designed for decorative and protective purposes, it is usually composed of a transparent or semi-transparent colorant solution. The solution penetrates the wood without hiding the grain, and indeed often enhancing it. The main requirements of wood colorants are transparency, high saturation, high brilliance, good bleed and chemical resistance, good solvent compatibility and high light fastness.
Metal-complex solvent dye is mainly used in wood stains, printing inks, aluminum foil coloring, hot stamping foil coloring, paints, coatings, leather finishes, baking finishes, stationery ink and plastic coatings. Further more, metal-complex solvent dyes own following advantages: 1. excellent solubility; 2. good compatibility with most resins; 3. bright colors; 4. excellent chemical resistance; 5. free of heavy metals; 6. liquid form is available.
USES FOR SOLVENT DYES
Their very nature - soluble in non-polar mediums - allows their versatility and many uses. Oil or solvent dye is used in applications such as foil printing, printing inks, marking pens, ball point pens, candles and other waxes, polishes, leathers, wood stains, acrylic resins, varnishes & shellacs. They are used in signaling smoke and in the pyrotechnics industry. These dyes are also used to color lubricants in the automotive and industrial cutting industries. However, the most frequent application of solvent dyes is in the plastics industry. Within the indus-trial plastics community, solvent-based dyes are used to color a variety of solid materials, such as acetates, nylon, polyester, acrylics, PVC, PMMA, PETP, polystyrene and styrene monomers. In addition, many solvent dyes are used as components by the biological stain manufacturing community to produce stains that will identify various cell structure components in medical diagnostics and scientific research.
USAGE
1. Solvent dyes for Inks for rotogravure and rubber stereo printing; for coating copying paper and typewriter rib-bons; for ball point pens, and in printing inks as shading and brightening agents and for double tone effects.
