The product in question is High Quality Sulphur Black 1 with the CAS number 1326 - 82 - 5. Sulphur Black 1 is a synthetic organic dye that belongs to the sulphur dye class. It has a characteristic black color and is known for its relatively high color fastness.
Physical and chemical parameters: It is usually in the form of a powder or granules. The solubility in water varies depending on the specific formulation, but generally, it can be dispersed in water under certain conditions. It has a relatively stable chemical structure under normal storage conditions, with a melting point and boiling point that are characteristic of its chemical nature. The pH value of its aqueous solution may also influence its performance and stability.
One of the primary uses of Sulphur Black 1 is in the textile industry. It is widely used for dyeing cotton, viscose, and other cellulosic fibers. The dye provides a deep, rich black color that is highly sought - after in the production of various textile products such as clothing, home textiles, and industrial fabrics. Due to its good color fastness, the dyed textiles can withstand multiple washes and exposure to sunlight without significant color fading.
In addition to the textile industry, Sulphur Black 1 can also be used in the leather industry. It can be employed to dye leather products, giving them a uniform and long - lasting black color. This is especially useful in the production of high - quality leather goods such as shoes, bags, and belts.
When using Sulphur Black 1 for textile dyeing, the first step is to prepare the dye bath. The dye should be dissolved in water with the appropriate amount of auxiliaries such as reducing agents and alkalis. The concentration of the dye in the bath depends on the desired color depth. The textile material is then immersed in the dye bath and heated to a suitable temperature, usually around 60 - 80 degrees Celsius. The dyeing process may take some time, typically 30 minutes to 1 hour, depending on the type of fabric and the color requirements. After dyeing, the fabric needs to be rinsed thoroughly to remove any excess dye and auxiliaries.
For leather dyeing, the leather should be pre - treated to ensure good absorption of the dye. The dye solution is prepared in a similar way as for textile dyeing. The leather is then soaked in the dye solution for a certain period until the desired color is achieved. After dyeing, the leather needs to be dried and finished to improve its appearance and durability.
Case 1: A textile manufacturing company in India was facing challenges in achieving a consistent and long - lasting black color for their cotton t - shirts. They decided to use our High Quality Sulphur Black 1. After following the recommended dyeing process, they were able to produce t - shirts with a deep, rich black color. The color fastness tests showed excellent results, with minimal color fading even after 20 washes. This significantly improved the quality of their products and increased customer satisfaction.
Case 2: A leather goods manufacturer in Italy wanted to enhance the color of their leather bags. They used Sulphur Black 1 for dyeing. The dyeing process was smooth, and the leather bags obtained a uniform black color. The dyed leather showed good resistance to abrasion and color transfer, which was crucial for their high - end products. As a result, the manufacturer was able to increase the selling price of their leather bags and gain a stronger market position.
