Poplon (India)

This dye is applied from an aqueous solution, usually in the presence of electrolyte (common salt or Glauber’s salt), and fixed on fibers without the need for mordants. It exhibits moderate light and wash fastness and is often used in textile dyeing, yarn dyeing, paper tinting, and sometimes in leather and jute applications.

Direct Black E is a water-soluble direct dye that imparts a deep, bluish-black shade to cellulosic fibers like cotton, viscose, and jute. It is known for its excellent leveling properties, making it suitable for uniform dyeing in textile processes.
The dye is applied directly from an aqueous solution with the addition of common salt or Glauber’s salt to promote exhaustion onto the fiber. It is widely used in exhaust dyeing, padding, and paper coloring, offering good depth and penetration.

Applications: • Cotton fabric dyeing
• Paper and pulp coloration
• Jute and rayon products
• Occasionally used in leather surface shading

Properties:
• Tone: Bluish black
• Light fastness: Moderate to good
• Washing fastness: Moderate
• Solubility: Good in water

Direct Congo Red is a water-soluble diazo dye that produces a bright red to bluish-red shade on cellulosic fibers. It is historically significant as one of the earliest synthetic dyes and is known for its strong affinity to cotton and other cellulose-based fibers without the need for a mordant.
⸻
Applications: • Textiles: Used to dye cotton, viscose, and jute in exhaust and padding processes. • Paper Industry: For red tinting and shading. • Biological Staining: Widely used in microbiology and histology as a pH indicator                    and for staining amyloid in tissue samples. • Indicator Use: Acts as a pH indicator that changes color from red in basic                            solution to blue in acidic solution.

Reactive Golden Yellow HR is a dye that produces a golden yellow color when applied to cellulosic fibers like cotton and viscose. It's a type of "hot dye," meaning it's applied under strong alkaline conditions and high temperatures to achieve excellent wash and light fastness. This dye forms a covalent bond with the fiber, improving color stability and washability. Here's a more detailed breakdown:Type: Reactive dye, specifically a "hot dye".Color: Golden yellow.Application: Used for dyeing cellulosic fibers (cotton, viscose, etc.).Binding: Forms a chemical bond with the fiber for improved color fastness.Fastness: Good fastness properties to wash, perspiration, and light.CI Name: Reactive Orange 12.Usage: Suitable for printing on cotton and viscose.

Direct Sky Blue FF is a blue-colored dye that belongs to the group of direct dyes. It's a water-soluble anionic dye used to color various fibers, particularly cellulosic fibers like cotton, rayon, and linen. Direct dyes, like Direct Sky Blue FF, are known for their ability to bond directly with fibers, eliminating the need for a separate mordant. Here's a more detailed look at Direct Sky Blue FF: Key Characteristics: Type: Direct Dye Color: Blue Form: Typically available as a powder, but can also be found as a liquid concentrate Solubility: Soluble in water Application: Used to color various fibers, including cotton, rayon, and linen Bonding: Directly bonds with fibers via hydrogen bonding Features: Good lightfastness (resistance to fading in light), easy handling, and no need for fixing agents. Usage/Application: Dyeing of textiles, including apparel, home textiles, and industrial products Can be used to color organic solvents, hydrocarbon fuels, waxes, lubricants, and plastics

Reactive Red Me4BL is a bright red dye used for dyeing and printing on various textile materials, particularly cotton, viscose, and synthetics. It's known for its high substantivity (ability to bind to the fibers), excellent lightfastness, and good wetfastness. This dye is often used in industrial and artisanal dyeing applications due to its consistent, intense color and stability. Here's a more detailed look at its usage:Dyeing and Printing:Me4BL is used for both dyeing (applying color to the entire fabric) and printing (applying color to specific designs on the fabric). Fibers:It works well on a variety of fibers, including cotton, viscose, nylon, and polyester. Fastness Properties:It provides excellent lightfastness (resistance to fading in sunlight) and good wetfastness (resistance to color loss when wet). Migration Resistance:Me4BL has high migration resistance, meaning it stays where it's applied and doesn't bleed or move to other areas of the fabric. Application Examples:It's a popular choice for creating vivid, durable reds in a wide range of textiles, according to IndiaMART. Reactive Dyes:Reactive dyes, like Me4BL, form a chemical bond with the fiber, making the color more permanent and durable.
