The textile industry is continually evolving, driven by demands for efficiency, sustainability, and innovative functionalisation methods. One proven technology that addresses these needs is the rotor spray system developed by WEKO. Though not a new concept, this precise, contactless, and minimal application system remains a key solution for applying liquid finishes to textiles, ensuring high performance and eco-friendly processing.

How WEKO Rotor Spray Technology Works
At the heart of WEKO‘s system lies its ingenious design, which ensures precision and efficiency. The process begins with a fluid supply unit, which delivers the desired treatment liquid to the rotor carrier. This rotor carrier houses multiple spinning discs, known as rotor discs, that atomise the fluid into fine droplets. The liquid is applied evenly onto the textile surface as it moves through the spray zone. The rotor spray technology’s hallmark is its ability to deliver functional finishes in minimal, controlled quantities without direct contact with the fabric.

Advantages of WEKO Rotor Spray Technology
WEKO’s rotor spray technology ensures a uniform application of liquids across the textile surface. This level of precision is particularly crucial for functionalising textiles where even minor deviations can affect performance.

The non-contact application of the WEKO system eliminates mechanical stress on fabrics, preserving their structure and appearance. This is especially beneficial for delicate or high-value textiles, as it reduces the risk of damage during the application process.

Sustainability is a growing concern in the textile industry, and WEKO addresses this challenge head-on. By delivering only the required amount of liquid, the rotor spray system minimises waste, reduces water consumption, and lowers energy costs during subsequent drying processes. With no need to mix large amounts of liquor that may later go unused, significant savings in fresh water and chemicals are achieved. Furthermore, as no extra liquid ends up on the fabric web, it is quite possible that the drying time and therefore the energy requirement can also be reduced. This fits in perfectly with the industry‘s switch to more environmentally friendly, resource-efficient processes.

The rotor spray technology is compatible with a wide range of functional liquids, including water-repellent coatings, antimicrobial agents, flame retardants, and softeners. This versatility makes it an ideal solution for manufacturers seeking to enhance the performance and functionality of their textiles. Whether single-sided, double-sided or different functions on both sides—just as required.

Examples in Textile Functionalisation
The WEKO rotor spray system is transforming how textiles are treated, offering solutions for both standard and new applications. Here are a few examples —of course, there are many other areas of application:

Water-Repellent Finishes: Achieving effective water-repellent properties is essential for outdoor and technical textiles. The precise application of hydrophobic agents ensures excellent performance while minimising chemical use.

Antimicrobial Treatments: With growing demand for hygiene-focused textiles in healthcare, sportswear, and home applications, the rotor spray system provides an efficient means of applying antimicrobial agents, ensuring durability and effectiveness.

Flame Retardant Coatings: Safety regulations often necessitate the application of flame-retardant finishes, particularly for textiles used in furnishings or protective clothing. WEKO’s system ensures these coatings are applied with precision, avoiding excessive chemical usage while meeting safety standards.

Softening Treatments: Achieving the desired hand feel is vital in many textile applications. The rotor spray system allows manufacturers to fine-tune the application of softeners, creating textiles that meet specific customer preferences.

The Economic Edge
Beyond its technical benefits, WEKO’s rotor spray technology offers significant economic advantages. The precise control over liquid application reduces the overall consumption of chemicals and water, leading to lower operating costs. Additionally, the system’s energy efficiency in drying processes further enhances cost savings, making it an attractive investment for manufacturers.
