In the field of textile processing, achieving durable and reliable waterproofing while balancing environmental protection and cost is a core challenge faced by many practitioners. Traditional fluorine-containing water repellents are restricted in application due to environmental and regulatory pressure, while some alternatives often suffer from non-durable waterproofing, compromised fabric hand feel or incompatibility with subsequent processes.
Chemi Tech's oil-based fluorine-free water repellent is an innovative solution developed precisely for these pain points. It adopts a unique molecular structure design and, without containing fluorocarbons, can form a uniform, firm protective film on the surface of the fabric fibers. This film effectively reduces the fabric's surface tension, preventing water droplets from soaking in and making them roll off quickly, thereby achieving an excellent waterproofing effect. Its oil-based nature ensures good compatibility with a variety of synthetic and blended fabrics, and the treated fabric not only has outstanding waterproofing performance but also retains its original softness and breathability.
Our solution is clear and easy to implement: step one, pre-treatment. Ensure the fabric to be treated is clean and free of residual impurities so that the water repellent adheres evenly. Step two, dilution and preparation. According to the fabric type and the required waterproofing grade, mix the Chemi Tech water repellent with a diluent in the recommended ratio. Step three, application processing. It can be treated through conventional processes such as padding, spraying or coating. Step four, drying and curing. Carry out heat treatment at an appropriate temperature so that the water repellent firmly crosslinks into a film on the fibers. The whole process is easy to integrate into existing production lines.
For example, a manufacturer specializing in outdoor functional backpacks needed its nylon fabric to have long-term rain resistance. It used Chemi Tech's oil-based fluorine-free water repellent for treatment. After standard process treatment, the fabric achieved an excellent waterproofing rating in laboratory tests, and in the subsequent simulated real-use wear tests, the decline in waterproofing performance was significantly lower than that of the products used previously. The customer reported that the treated backpack fabric maintained a good appearance and hand feel, satisfying end consumers' dual expectations for product performance and quality.
