The advanced formulation delivers exceptional black coloration with superior covering power and outstanding heat resistance properties. Manufactured using state-of-the-art production technology, the product ensures uniform particle size distribution and excellent solubility characteristics. These properties enable outstanding performance across various dyeing processes, providing users with consistent and reliable coloration results. The dye's versatility and reliability have made it an essential component for manufacturers seeking high-quality black pigmentation solutions across multiple industrial applications.

Before dyeing, dissolve solid sulfur black in hot water at required concentrations with thorough agitation until complete dissolution is achieved. For textile dyeing applications, use dye concentrations of 2-8% based on fabric weight, maintaining dyeing temperature at 85-95℃ for 45-90 minutes duration.

In leather dyeing processes, apply 1-5% based on leather weight in combination with appropriate penetrating agents and fixing agents for optimal results. For other industrial applications, adjust dosage according to desired color depth, typically ranging from 0.1-3% concentration. Following dyeing operations, conduct appropriate post-treatment processes to ensure color fastness and product quality. Proper dissolution and temperature control are essential for achieving uniform coloration and maximum dye utilization efficiency.

Extensively utilized throughout the textile dyeing industry, particularly excelling in black coloration of cotton fabrics, linen textiles, and other natural fiber materials. Leather industry applications encompass dyeing processes for various leather products and accessories requiring deep black coloration.

Paper manufacturing utilizes the dye for specialty black paper production where consistent color quality is essential. Rubber industry applications include colorant functions for tire manufacturing, rubber hoses, and various rubber products. Plastic industry implementations involve black plastic product coloration across diverse manufacturing processes. Construction coating applications utilize the dye as a black pigment for architectural and industrial coatings. Paint and coating industry applications provide deep black coloration effects for automotive, industrial, and decorative coating formulations requiring superior color intensity and durability.
