Description

Lanasolscarlet2R CAS NO 12270-86-9 is a specialized, high-performance reactive dye belonging to the Lanasol series, designed for the vibrant and durable coloration of protein-based fibers. Its core value lies in its excellent fastness properties, including superior wash and light fastness, which are critical for high-quality textile production. This product is essential for manufacturers in the textile and leather industries seeking brilliant scarlet shades on wool, silk, and nylon substrates. Its reactive nature ensures strong covalent bonds with the fiber, resulting in long-lasting, vivid color that meets the demands of premium apparel and specialty fabrics.

Application

• Primary dyeing and printing of wool and other animal hair fibers.
• Coloration of silk fabrics and yarns for luxury apparel and accessories.
• Dyeing of polyamide (nylon) fibers for textiles and carpets.
• Production of high-fastness, vibrant scarlet shades in knitwear and woven fabrics.
• Used in the leather industry for dyeing high-grade leather goods.
• Formulation of specialty dye mixtures to achieve specific color shades.
