Manufacturing Processes of Rubber Coated Textiles
Spread Coating Process
The spread coating process, also known as knife coating, is a prevalent method in the production of rubber coated textiles. This technique involves using a precision knife to apply a solvent-based polymer coating onto fabric. The fabric is placed under tension beneath the blade, allowing for precise control over the coating thickness. This method facilitates the application of various weights of coatings on one or both sides of the material.
Calender Coating Process
Calender coating is another common technique used in the creation of rubber coated textiles. This involves passing the fabric through a series of rollers that apply the rubber compound uniformly across the surface. This method is particularly effective in producing thicker coatings and is often used for fabrics requiring enhanced durability.
Curing and Vulcanization
Once the coating is applied, the fabric undergoes a curing process. This involves heating the coated fabric in specially designed ovens, allowing the solvent to evaporate and the rubber to vulcanize. Vulcanization chemically alters the rubber, enhancing its elasticity, strength, and durability. The final product boasts a strong bond between the rubber and fabric, resulting in a solid yet flexible material.
Benefits of Rubber Coated Textiles
Enhanced Durability
Rubber coated fabrics are significantly more durable than uncoated fabrics. They exhibit resistance to wear and tear, making them ideal for applications in harsh environments. For instance, Zenith Rubber offers rubber coated fabrics that can withstand abrasion, ensuring longevity in demanding situations.
Weather and Temperature Resistance
Many rubber coated textiles are designed to resist adverse weather conditions and extreme temperatures. This characteristic is crucial for applications in marine and aviation industries, where exposure to elements can compromise material integrity. Products from American Rubber Products are noted for their weather resistance, providing reliable performance in various conditions.
Chemical and Oil Resistance
Rubber coated fabrics can also provide excellent resistance to chemicals and oils. This feature is particularly important in industrial settings where exposure to hazardous materials is common. Fabrics coated with materials like Nitrile and Chloroprene, as mentioned by Zenith, are specifically designed for such applications.
Electrical Conductivity
Some rubber coated fabrics possess electrical conductivity, making them suitable for specialized applications. This feature allows these textiles to be used in environments where static buildup could pose a risk, such as in aerospace and defense sectors.
Applications of Rubber Coated Textiles
Marine Industry
Rubber coated textiles are extensively used in the marine industry for products like inflatable boats and life rafts. Their water resistance and durability ensure safety and reliability in aquatic environments.
Aerospace Applications
In the aerospace field, rubber coated fabrics are utilized for a variety of applications, including air retention and protective coverings. The lightweight nature of these textiles combined with their strength makes them ideal for aircraft components.
Industrial Use
Industrial fabrics, such as those used in geotextiles and civil structures, benefit from the abrasion resistance and chemical properties of rubber coatings. These textiles provide added protection and functionality in construction and engineering projects.
Medical and Healthcare
In the medical industry, rubber coated fabrics are employed for protective clothing and medical substrates. Their washable and durable nature ensures compliance with hygiene standards while providing necessary protection.
Environmental Control
Rubber coated textiles are gaining traction in environmental pollution control applications. Their low permeability and durability make them suitable for use in barriers and filtration systems.
