The textile industry relies heavily on dyes that can impart vibrant, long-lasting colors to various fibers. For synthetic fibers, particularly polyester, solvent dyes offer unique advantages due to their solubility in non-polar media and their ability to provide excellent color properties. Solvent Red 135 (CAS 20749-68-2) is a prime example of a high-performance solvent dye that is increasingly utilized in advanced textile applications, including PET spinning and dyeing. As a leading manufacturer and supplier of specialty dyes in China, we understand the critical requirements for textile coloration.

Solvent Red 135 is well-suited for synthetic fiber dyeing, especially polyester (PET), due to its chemical structure and performance characteristics. Its benefits for textile applications include:

  • Excellent Affinity for Polyester: The dye's molecular structure allows for good diffusion and fixation within the polyester fiber matrix, leading to deep and uniform coloration.
  • High Heat Stability: Polyester dyeing often involves high temperatures during the spinning or dyeing process. Solvent Red 135's high heat resistance ensures that the color remains stable and does not degrade.
  • Superior Lightfastness: Textiles colored with Solvent Red 135 exhibit excellent resistance to fading when exposed to light, ensuring the color fastness of the final garment or fabric.
  • Vibrant Red Hue: It provides a brilliant and attractive red shade that is desirable in fashion and home textiles.
  • Good Washing and Rubbing Fastness: While solvent dyeing is different from water-based textile dyeing, the inherent stability of Solvent Red 135 contributes to good fastness properties in the finished product.
