NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of advanced chemical auxiliaries, with a strong emphasis on textile finishing solutions. Among their comprehensive product range, the optical brightener for cotton dyeing stands out as a critical component for achieving superior fabric aesthetics. Cotton, a widely used natural fiber, often possesses a slight yellowish hue that can be effectively masked and overcome by the strategic application of fluorescent whitening agents.

The optical brightener BA-550, for instance, is an anionic fluorescent whitening agent that performs exceptionally well on cotton. Its ability to absorb UV light and re-emit it as visible blue light significantly boosts the perceived whiteness and brightness of cotton fabrics. For manufacturers, optimizing the dyeing process is key. This involves precise control over several parameters. A typical application involves a liquor ratio of 1:10 to 1:30, ensuring adequate bath availability for the fibers. The concentration of the brightener usually ranges from 0.05% to 0.4% based on the weight of the fiber (o.w.f.). The treatment is carried out at elevated temperatures, generally between 80°C to 100°C, for a duration of 30 to 60 minutes to ensure thorough diffusion and fixation of the agent onto the cotton fibers.

By meticulously following these guidelines for optical brightener for cotton dyeing, textile mills can achieve a remarkable improvement in fabric whiteness, leading to a more luxurious and appealing final product. This enhanced appearance is crucial for market competitiveness, as consumers often associate brighter whites with higher quality and cleanliness.
