What is Leather Chemicals？
 

Leather chemicals encompass a diverse range of substances that are crucial to the leather-making process. Several chemicals are used in various stages of this process to achieve the desired quality and characteristics of leather products. These chemicals include substances used in the beam house and tanyard, biocides, surfactants, degreasers, swell-regulating agents, lime, and more.

Advantages of Leather Chemicals

 

Dispersant NNO Sodium Naphthalene Sulfonate Formaldehyde CAS NO.:36290-04-7

These chemicals improve quality by enhancing the softness, durability, and overall look of leather products.
They contribute to uniform dyeing, preventing inconsistencies in color and appearance.
They accelerate and optimize the tanning process, reducing production time and resource consumption.
They impart anti-microbial properties to leather, preventing the growth of harmful microorganisms.
Eco-friendly leather chemicals support sustainable and environmentally responsible leather production.
Efficient chemical processes contribute to reduced water and energy consumption, minimizing the environmental footprint of leather production.
Chemical treatments provide leather with stain-resistant properties, making it easier to clean and maintain.
A wide range of chemicals allows for the customization of leather characteristics, catering to diverse preferences in the market.

 

 
Tanning Process Of Leather Chemicals
 
01/

Soaking
Soaking is done to remove any excess salt or dirt. All non-leather making components should be removed from the hide to prepare for the production a clean and flat pelts.

02/

Liming
The goal of liming is to split the fibre bundles and to remove any unwanted hair from the hide through the introduction of alkali. Hair saving or semi-hair saving systems yield particularly good results.

03/

De-liming
The pelt requires an efficient and complete removal of lime and the neutralization of residual alkalinity, after fleshing and/or splitting. This is done most effectively using proprietary organic acids and acid-salts which form highly soluble lime complexes.

04/

Bating
The network of elastin fibers, which are insoluble in the highly alkaline conditions of liming, should now be evenly relaxed and flattened through the extended action of suitable enzyme preparations.

05/

Pickling
Acids are added to slacken the pelt and enhance penetration of the tanning agent.

06/

Tanning
By using a tanning agent the collagen structure of a pelt is being altered and converted into a leather intermediate. It is now a durable material and protected against chemicals, moisture and microorganisms.

 

 

Functions Of Leather Chemicals

 

 

Sodium sulfide: It breaks down the proteins that hold the hair and flesh to the hides, making them easier to remove.

 

Lime: It removes unwanted materials from the hides and softens them for further processing.

 

Chrome: It stabilizes the proteins in the hides, preventing them from decomposing and ensuring durability.

 

Vegetable tannins: They provide a natural and organic tan to the leather, which is preferred by some consumers.

 

Dyes: They add color to the leather, making it more appealing to consumers.

 

Fatliquors: They add softness and flexibility to the leather, making it more comfortable to wear.

 

Coatings: They protect the leather from water, dirt, and other environmental factors, ensuring its durability.

 

 

Application of Leather Chemicals
 

Municipal Water Treatment: Applied in municipal water treatment plants for the purification of drinking water, ensuring it meets regulatory standards for safety and quality.

 

Paper and Pulp Industry: Employed as a key component in the clarification and purification of water used in paper and pulp manufacturing processes.

 

Textile Industry: Utilized for the treatment of wastewater generated in the textile industry, aiding in the removal of dyes and contaminants.

 

Water Treatment: Applied in water treatment processes for the removal of sulfate ions, contributing to the purification of water in industrial and municipal settings.

 

Laboratory Reagent: Used as a laboratory reagent for analytical and research purposes, demonstrating its versatility in scientific applications.

 

Pyrotechnics: Employed in the pyrotechnics industry for the creation of green flame effects in fireworks and other pyrotechnic displays.

 

 

FAQ

 

 

Q: What chemicals are used in leather?

A: Tanning chemicals include calcium hydroxide, sodium sulfide, sulfuric acid, formic acid, hydrogen sulfide, aniline-based dyes, and solvents (dichloromethane, benzene, ethanol, tetrachloroethane, trichloroethylene). Finishing chemicals include formaldehyde, aniline, nitrocellulose, and resins.

Q: What is the role of preservatives in leather chemicals?

A: Preservatives in leather chemicals are mainly used to prevent leather from being eroded by microorganisms such as mold and bacteria during storage and use, thereby extending the service life of leather.

Q: How to ensure safety when using leather chemicals?

A: When using leather chemicals, protective gloves and masks must be worn, and it is strictly forbidden to directly contact the skin with chemicals. Once accidentally splashed on the skin, it should be rinsed with clean water immediately. At the same time, ensure good ventilation to prevent the accumulation of harmful gases.

Q: What is the chemical composition of leather?

A: Fresh hides consist of water, protein, fatty materials and some mineral salts. The most important for leather making is the protein. This protein may consist of many types: Collagen- on tanning gives leather; keratin- constituent of hair, wool, horn and epidermal structures.

Q: What chemical is used in leather making?

A: Traditionally, a chemical compound called tannin was used to process the skins to produce leather. Tannin was derived from the bark of specific trees. Alternative methods were developed in the 1800's, when chrome tanning and chromium salts were used instead of natural tannins.

Q: What is the chemical treatment for leather?

A: The preservation process employed is a chemical treatment called tanning, which converts the otherwise perishable skin to a stable and nondecaying material. Tanning agents include vegetable tannins (from sources such as tree bark), mineral salts (such as chromium sulfate), and fish or animal oils.

Q: How to deal with leather chemical waste?

A: Leather chemical waste needs to be treated in accordance with relevant environmental protection regulations. Generally speaking, the hazards and emissions of pollutants can be reduced by chemical treatment, physical treatment or biological treatment.

Q: What is the chemical composition of leather?
