NINGBO INNO PHARMCHEM CO.,LTD. is pleased to introduce Fluo-free WF Plus, a cutting-edge, fluorine-free waterproofing agent specifically designed for the textile industry. This product represents a significant advancement in sustainable textile finishing, offering superior water repellency without the environmental concerns associated with traditional per- and polyfluoroalkyl substances (PFAS).

Fluo-free WF Plus is presented as a milky-white liquid dispersion, formulated based on a sophisticated polyurethane polymer chemistry. This composition provides a highly effective barrier against water, making textiles hydrophobic and suitable for applications requiring protection from rain and moisture. Its ionic character is described as cationic/non-ionic, contributing to its compatibility and performance in various finishing baths.

The primary application of Fluo-free WF Plus is for water repellent and rainproof finishing on synthetic fibers and their blends. This makes it particularly suitable for use in the production of outdoor sportswear, women's and men's outerwear, and leisure wear, where protection from the elements is crucial. The demand for high-performance, yet environmentally conscious textile treatments is rapidly growing, and Fluo-free WF Plus meets this need head-on.

One of the key advantages of Fluo-free WF Plus is its high water repellency, ensuring excellent rain and splash protection for finished fabrics. Beyond just repellency, the product exhibits good running properties during application, including negligible foaming behavior and low roller build-up. This contributes to smoother and more efficient production processes for textile manufacturers.

Durability is another critical feature. Fluo-free WF Plus offers excellent durability to laundering, specifically demonstrating good retention of its protective properties after multiple washing cycles, even without subsequent ironing. This longevity ensures that garments maintain their performance over time, enhancing consumer satisfaction.

The product also aids in the repellency of water-based stains and facilitates easy spot cleaning of garments. Furthermore, it offers the flexibility to be combined with additional extenders, such as fix agents, to potentially increase the durability level, depending on specific performance requirements.

Application of Fluo-free WF Plus is typically carried out using the padding process, a common and effective method in textile finishing. The process involves preparing a bath by diluting the product with cold water and adjusting the pH, usually with acetic acid, to approximately 4.0-5.0. Recommended application parameters include a pick-up rate of around 40-80%, depending on the fiber type, and a bath temperature of about 20-25 °C. Drying is typically done at 110-130 °C, followed by curing. Separate curing can be performed at 150 °C for 5 minutes, or a rapid curing process can be utilized in stages on a stenter at 110-170°C for 45-60 seconds. The required amount of Fluo-free WF Plus generally ranges from 30 to 100 g/l in the finishing bath.

Achieving optimum finishing results necessitates careful preparation of the goods. Fabrics should be free of residual processing chemicals like wetting agents, dyeing auxiliaries, sizing residues, softeners, and other surface-active compounds that could impair the desired effects. Mechanical treatments such as calendering, schreinering, and brushing are ideally performed after drying but before curing, while steaming and decatizing processes can follow curing. Raising and emerizing should precede the finish application.

The shift towards fluorine-free waterproofing agents like Fluo-free WF Plus is driven by increasing environmental regulations and consumer demand for more sustainable products. PFAS chemicals, traditionally used in durable water repellent (DWR) finishes, are known for their persistence in the environment and potential health concerns. Polyurethane-based alternatives offer a more environmentally friendly profile while still providing excellent water repellency and durability when properly formulated and applied. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting this industry transition with high-quality, effective solutions.

Fluo-free WF Plus offers a robust solution for textile manufacturers seeking to produce high-performance, water-repellent fabrics that meet modern environmental standards. Its liquid form allows for easy handling and integration into existing padding processes. The product is stable for at least one year when stored correctly in closed containers at 20°C, although care must be taken to avoid exposure to temperatures below 0°C or above 50°C. It is packaged in convenient 120kg, 125kg plastic barrels or larger IBC tanks to suit different production scales.

For textile companies looking to enhance their product lines with sustainable and effective waterproofing, Fluo-free WF Plus from NINGBO INNO PHARMCHEM CO.,LTD. presents an excellent option.
