Brand World vat dyes produced by Jiangsu World Chemical Co., Ltd. belong to the type of anthraquinone and anthracene ketones, which is applied for the dyeing of cotton, linen, rayon and blended fabric materials. It appears to the environmental dustproof particles with very good water diffusion, uniformity of dispersion and anti- cohesion of suspension. It is particularly applicable to high-speed continuous dyeing and continuous padding with automatic mixing owning to its fast speed of reduction. While it is also suitable for hidden color and suspension dyeing processes in deep-dyeing. Excellent fastness in each index It is especially for high fastness request areas and irreplaceable by other types.
