The textile industry constantly strives for pristine white fabrics that appeal to consumers. Achieving this level of brightness often requires sophisticated chemical treatments, and optical brighteners are key players. Among these, Fluorescent Brightener 220 (CAS 16470-24-9) stands out for its effectiveness, particularly with cotton and viscose fibers. As a specialized chemical supplier, we provide this vital ingredient to textile manufacturers seeking superior results.

Understanding Fluorescent Brightening in Textiles

Fluorescent brighteners absorb UV light and re-emit it as visible blue light, masking any natural yellowing in fibers and making them appear whiter. This process is crucial for achieving the brilliant white shades demanded in fashion, home textiles, and industrial fabrics. The selection of an appropriate brightener depends on the fiber type, processing conditions, and desired shade.

Fluorescent Brightener 220 for Cotton and Viscose

Fluorescent Brightener 220 is particularly well-suited for cellulosic fibers like cotton and viscose rayon. Its anionic nature and good water solubility allow for easy application in textile processing baths. When you buy this product from a reliable manufacturer, you ensure consistent performance and a vibrant white finish.

Key benefits for textile applications include:

  • Excellent Affinity: It demonstrates good affinity to cellulosic fibers, ensuring effective and even whitening.
  • Bright White Shade: It produces a clean, bright white with a subtle blue tone, masking yellowness effectively.
  • Process Compatibility: It can be used in various textile finishing processes, including padding and incorporation into whitening printing pastes.
  • Stability: It shows good stability to alkaline conditions and is compatible with peroxide bleaching agents, offering flexibility in formulation.

As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers Fluorescent Brightener 220 at competitive prices. We ensure that our product meets high standards for purity and performance, enabling textile producers to achieve their desired whitening effects reliably.

Application Methods in Textiles

Fluorescent Brightener 220 can be applied through several methods:

  • Pulp Whitening: While primarily used in paper, similar principles can apply to cellulose processing in textiles.
  • Padding Method: Fabrics are typically passed through a solution containing the brightener at elevated temperatures (e.g., 95-98°C) for a specific residence time, followed by steaming.
  • Whitening Printing Pastes: The brightener can be incorporated into printing pastes for localized whitening effects.

The recommended dosage can vary, but typically ranges from 0.1% to 0.5% of the weight of the processing liquor. Proper application is key to achieving optimal results without over-application, which can lead to dullness or color shifts.
