The background and importance of leather tanning process
The leather tanning process is the process of transforming animal skin into a durable, soft material with specific physical and chemical properties. This process not only gives the leather excellent mechanical strength and durability, but also makes it waterproof and corrosion-resistant, and is widely used in clothing, footwear, furniture, automotive interiors and other fields. Traditionally, leather tanning mainly relies on vegetable tanning agents (such as cannabis glue) and chromium tanning agents, but these methods have many environmental and health problems. For example, the hexavalent chromium in chromium tanning agents is harmful to the human body and can occur during the treatment process. A large amount of polluted wastewater.
With the increase in environmental awareness and the popularization of sustainable development concepts, traditional leather tanning processes face huge challenges. Governments and industry organizations in various countries have issued strict environmental regulations to limit the use of hazardous substances and require enterprises to reduce wastewater emissions and energy consumption. Against this background, developing new and environmentally friendly leather tanning technologies has become the top priority. Low atomization odorless catalysts, as an innovative chemical, provide new ideas and solutions to these problems.
The application of low atomization and odorless catalysts in leather tanning can not only significantly improve production efficiency, but also effectively reduce the emission of harmful substances and reduce the impact on the environment. Its unique chemical properties allow it to quickly catalyze reactions under low temperature conditions, shorten the tanning time, while avoiding the odor and release of volatile organic compounds (VOCs) caused by traditional tanning agents. In addition, the catalyst also has good stability and reusability, which can greatly reduce the production costs of the enterprise and improve economic benefits.
To sum up, the application of low atomization and odorless catalysts is not only a technological advancement in the leather tanning process, but also a key step in promoting the development of the entire industry towards a green and sustainable direction. This article will conduct in-depth discussion on the specific application of low-atomization odorless catalysts in leather tanning, and analyze its advantages, limitations and future development prospects.
The basic principles of low atomization and odorless catalyst
Low atomization and odorless catalyst is a new type of high-efficiency catalyst, widely used in leather tanning processes. Its basic principle is to promote the progress of key reactions during the tanning process through special chemical structures and reaction mechanisms, thereby improving tanning efficiency and reducing the generation of harmful by-products. The core features of these catalysts are “low atomization” and “odorless”, which means they do not produce obvious mist or pungent odor during use, avoiding the common environmental pollution and worker health risks of traditional catalysts.
Chemical composition and structure
The low atomization and odorless catalyst is usually composed of a variety of active ingredients, mainly including metal complexes, organics and their derivatives, surfactants, etc. Among them, metal complexes are the main active centers of the catalyst, and common metal ions include cobalt, zinc, titanium, etc. These metal ions accelerate the crosslinking reaction between the tanning agent and the skin fibers by forming a stable complex with the intermediates generated during the tanning process. Studies have shown that the presence of metal ions can significantly reduce the reaction activation energy and enable the tanning process to be completed quickly at lower temperatures.
Organics and their derivatives play a supporting catalysis role, which can adjust the pH of the reaction system and ensure that the tanning reaction is carried out under a suitable alkaline environment. In addition, organic can also act as a reducing agent to help remove oxidation products generated during the tanning process and prevent excessive cross-linking and hardening of the skin fibers. Common organics include lemon, tartar, etc. These natural-derived substances have good biodegradability and meet environmental protection requirements.
Surfactants are another important component of low atomization odorless catalysts. They promote penetration and uniform distribution of tanning agents in the skin fibers by reducing the surface tension of the liquid, improving the tanning effect. At the same time, the surfactant also has a certain emulsification effect, which can effectively disperse the tiny particles generated during the tanning process, prevent them from precipitating and aggregation, and maintain the stability of the reaction system. Commonly used surfactants include nonionic and anionic. The former has better water solubility and biocompatibility, while the latter exhibits higher activity under strong conditions.
Reaction mechanism
The reaction mechanism of low atomization odorless catalyst can be divided into the following steps:
-
Adhesion and activation: The catalyst first adheres to the surface of the skin fibers through physical adsorption or chemical bonding, and then interacts with the tanning agent molecules to form an active intermediate. This process makes the tanner molecules more easily accessible to the active sites in the skin fibers, thus speeding up the progress of subsequent reactions.
-
Crosslinking reaction: Under the action of a catalyst, the tanner molecule undergoes cross-linking reaction with the protein chain in the skin fibers, forming a stable three-dimensional network structure. This process not only enhances the mechanical strength and durability of the leather, but also gives the leather good flexibility and elasticity. Studies have shown that low atomization and odorless catalysts can significantly improve the selectivity and efficiency of the tanning reaction, reduce unnecessary side reactions, and thus obtain better leather products.
-
Dehydration and Curing: After the cross-linking reaction is completed, the catalyst continues to promote the evaporation and curing of the internal moisture of the leather, further improving the physical properties of the leather. The dehydration process not only helps remove excess moisture, but also eliminates theThe odor and volatile organic compounds (VOCs) generated during the tanning process ensure the odorless properties of the final product.
-
Stability and Protection: Afterwards, the catalyst combines with the active groups on the surface of the leather to form a protective film to prevent the external environment from eroding and aging of the leather. This protective film not only improves the corrosion resistance and wear resistance of the leather, but also extends its service life.
Environmental and Safety Performance
The design of low atomization and odorless catalyst fully takes into account environmental protection and safety factors. First of all, the catalyst itself has good biodegradability and can quickly decompose into harmless substances in the natural environment without causing persistent pollution to the ecosystem. Secondly, no toxic gases or volatile organic compounds are produced during the use of the catalyst, which avoids the common air pollution problems in traditional tanning processes. In addition, the low atomization properties of the catalyst allow operators to wear complex protective equipment, reducing occupational health risks.
To sum up, low atomization odorless catalysts not only improve the efficiency and quality of leather tanning, but also significantly reduce the negative impact on the environment and health through their unique chemical composition and reaction mechanism. This innovative technology provides strong support for the sustainable development of the leather industry.
Specific application of low atomization and odorless catalyst in leather tanning process
The low atomization and odorless catalyst has a wide range of applications in leather tanning processes, covering multiple links from pretanning to post-treatment. Its excellent catalytic properties and environmentally friendly properties make it an indispensable key material in modern leather processing. The following is the specific application and effect analysis of the catalyst at different tanning stages.
Pretanning stage
Pretanning is a step in leather tanning, designed to initially fix the leather fibers to prevent them from deformation or dissolving during subsequent treatments. Traditional pre-tanning methods mostly use salt marinating, lime impregnation and other methods, but these methods often lead to excessive expansion and hardening of the skin fibers, affecting the quality of the final product. The introduction of low atomization and odorless catalysts has completely changed this situation.
In the pretanning stage, low atomization odorless catalysts can work in the following ways:
-
Promote the initial cross-linking of skin fibers: The catalyst and pretanning agents (such as alum, sulfur aluminum, etc.) work together to accelerate the cross-linking between protein chains in skin fibers and tanning agent molecules. reaction. Studies have shown that pretanning treatment with low atomization and odorless catalysts can increase the crosslinking degree of leather fibers by about 30%, significantly enhancing the newborn structural stability of leather.
-
Reduce the expansion of skin fibers: The catalyst can adjust the pH value of the pre-tanning liquid, inhibit excessive expansion of skin fibers, and prevent it from rupturing or falling off during subsequent tanning. The experimental results show that the expansion rate of the leather fibers treated with low atomization and odorless catalysts has been reduced by about 25%, greatly improving the quality and yield of the leather.
-
Shorten pretanning time: Due to the efficient catalytic action of the catalyst, the pretanning reaction can be completed at lower temperatures and in a shorter time, thus saving a lot of energy and time costs. According to a foreign study, a pretanning process using low atomization odorless catalysts can shorten the processing time to 60%, greatly improving production efficiency.
Main Tanning Stage
Main tanning is the core link of leather tanning, which determines the final performance and quality of leather. Traditional main tanning methods mostly use chrome tanning agents. Although the effect is significant, there are serious environmental pollution and health risks.

Improve the appearance and feel of leather: The catalyst can promote the uniform distribution of tanning agents in the leather fibers, avoid local over-tanning or under-tanning, and make the appearance of leather more uniform. In addition, the catalyst can also give the leather better softness and elasticity, improving the touch and comfort of the product.
Post-processing phase
Post-treatment is the next step in leather tanning, aiming to further improve the physical properties and appearance quality of the leather. Traditional post-treatment methods mostly use methods such as fat addition, dyeing, and finishing, but these methods often require a large amount of chemicals and energy, which increases production costs and environmental burden. The introduction of low atomization odorless catalysts provides a new way to optimize the post-treatment process.
In the post-treatment stage, the main applications of low atomization and odorless catalysts include:
-
Promote the penetration of fat-adding agents: The catalyst can reduce the surface tension of the fat-adding agent, promote its penetration and uniform distribution in the leather fibers, and improve the softness and wear resistance of the leather. Studies have shown that grease treatment with low atomization odorless catalysts can increase the softness of the leather by about 20% and wear resistance by about 15%.
-
Accelerating dyeing and color fixation: Catalysts can promote the binding between dye molecules and skin fibers, speed up dyeing and color fixation speed, and shorten the processing time. According to a foreign study, a dyeing process using a low atomization odorless catalyst can shorten the processing time to 60% and the dyeing effect is more vivid and long-lasting.
-
Improve the coating effect: The catalyst can enhance the bonding force between the coating agent and the leather surface, prevent the coating from falling off or cracking, and improve the appearance quality and protective performance of the leather. Experimental data show that coating treatment using low atomization odorless catalyst can increase the adhesion of the coating by about 30% and the wear resistance by about 25%.
-
Reduce the release of volatile organic compounds (VOCs): The low atomization properties of the catalyst make it hardly produce volatile organic compounds during the post-treatment process, avoiding harm to the environment and workers. According to a domestic study, a post-treatment process using low atomization odorless catalysts can reduce the release of VOC by about 90%, greatly improving the working environment.
