What are the applications of Dicyandiamide Powder in the leather industry?

Hey there! As a supplier of Dicyandiamide Powder, I've seen firsthand how this versatile chemical plays a crucial role in the leather industry. In this blog post, I'm gonna share with you some of the key applications of Dicyandiamide Powder in leather processing.

1. Tanning Agent

One of the primary applications of Dicyandiamide Powder in the leather industry is as a tanning agent. Tanning is a process that converts raw hides and skins into leather, making it more durable, resistant to decay, and suitable for various applications. Dicyandiamide can react with chromium salts to form a stable complex, which helps to fix the chromium ions in the leather fibers. This enhances the tanning effect, resulting in leather with better physical properties such as increased strength, flexibility, and color fastness.

The use of Dicyandiamide in tanning also has some environmental benefits. It can reduce the amount of free chromium in the tanning liquor, which is a major environmental concern in the leather industry. By forming a complex with chromium, Dicyandiamide helps to minimize the release of chromium into the environment, thus reducing pollution.

2. Retanning Agent

After the initial tanning process, leather often undergoes retanning to improve its quality and appearance. Dicyandiamide Powder can be used as a retanning agent to further enhance the properties of the leather. When used as a retanning agent, Dicyandiamide can penetrate into the leather fibers and react with the existing tanning agents and other chemicals in the leather. This helps to fill the voids in the leather structure, making it more compact and uniform.

As a result, the leather becomes softer, more flexible, and has a better grain appearance. Additionally, the use of Dicyandiamide as a retanning agent can improve the leather's resistance to water, heat, and abrasion, making it more suitable for high - quality leather products such as shoes, bags, and furniture upholstery.

3. Dye Fixative

Dyeing is an important step in leather processing to give the leather the desired color. However, ensuring that the dye adheres well to the leather and does not fade easily is a challenge. Dicyandiamide Powder can act as a dye fixative in the leather industry.

It can react with the dye molecules and the leather fibers, forming a chemical bond that helps to fix the dye in place. This significantly improves the color fastness of the leather, ensuring that the color remains vibrant and does not bleed or fade during use. Whether it's for light - colored or dark - colored leather, the use of Dicyandiamide as a dye fixative can help to achieve more consistent and long - lasting color results.

4. Formaldehyde Scavenger

Formaldehyde is commonly used in the leather industry for various purposes such as tanning, retanning, and finishing. However, formaldehyde is a toxic substance that can cause health problems such as skin irritation, respiratory problems, and cancer. In recent years, there has been a growing demand for reducing formaldehyde levels in leather products.

Dicyandiamide Powder can act as a formaldehyde scavenger. It can react with formaldehyde to form a stable compound, thereby reducing the free formaldehyde content in the leather. This is not only beneficial for the health of consumers but also helps leather manufacturers to meet the strict environmental and safety regulations regarding formaldehyde emissions.

5. Flame Retardant

In some applications, leather products need to have flame - retardant properties, such as in automotive interiors, aircraft seats, and some industrial leather goods. Dicyandiamide Powder can be used to impart flame - retardant properties to leather.

When incorporated into the leather during the processing, Dicyandiamide can decompose at high temperatures and release non - flammable gases. These gases can dilute the oxygen in the surrounding environment and prevent the spread of fire. Additionally, the decomposition products of Dicyandiamide can form a char layer on the surface of the leather, which acts as a barrier to heat and oxygen, further enhancing the flame - retardant effect.

Other Related Chemicals in the Leather Industry

In addition to Dicyandiamide Powder, there are other chemicals that are also commonly used in the leather industry. For example, Polyhexamethylene Guanidine is a broad - spectrum antibacterial agent that can be used to prevent the growth of bacteria and fungi on leather, extending its service life. Guanidine Phosphate Monobasic can be used as a buffering agent and pH regulator in leather processing, helping to maintain the optimal chemical environment for various reactions. And Pharmaceutical Grade Guanidine Carbonate can be used in some special leather treatment processes, such as in the production of high - quality leather for medical and cosmetic applications.
