Solution for Wet Rubbing Fastness of SILIT-PUR5998N on Dark High Density Fabrics

In the field of textile dyeing, the dyeing of dark fabrics, especially black denim and high-density woven fabrics, has long been a persistent challenge for the industry. Conventional auxiliaries often struggle to effectively enhance wet rubbing fastness when dealing with high-density, deeply dyed fabrics. Moreover, issues such as "oil slick & oil spots" frequently occur, severely compromising product quality and production efficiency. 

The advent of SILIT-PUR5998N Wet Rubbing Fastness Improver has now provided a solution to this predicament, redefining the standards of dark fabric dyeing with innovative technology.

SILIT-PUR5998N is specifically designed for dark fabrics, directly addressing industry pain points. One of its core advantages lies in solving the "oil slick & oil spots" problem that commonly plagues similar products, fundamentally enhancing production stability. In actual production, "oil slick & oil spots" not only cause visual defects on fabrics but also may lead to additional post-processing steps, resulting in cost overruns. SILIT-PUR5998N, with its unique formula and process, effectively avoids this issue, ensuring that every piece of dark fabric is delivered in perfect condition.

From a technical perspective

SILIT-PUR5998N demonstrates outstanding performance. It boasts exceptional stability, enabling the working solution to maintain excellent chemical stability even under complex processing conditions such as high temperatures and high mechanical forces. Whether in high-temperature dyeing processes or high-speed mechanical treatments, SILIT-PUR5998N functions stably, providing a reliable guarantee for production. Additionally, this improver features high efficiency and sustainability. While enhancing dyeing effects, it reduces wastewater pollution and fully complies with stringent international environmental standards such as OEKO-TEX® and REACH. This not only meets enterprises' pursuit of product quality but also aligns with the global environmental trend, achieving a win-win situation between economic benefits and environmental protection. Furthermore, SILIT-PUR5998N has a wide compatibility range, being applicable to fabrics dyed with reactive dyes, sulfur dyes, and indigo dyes. It is adaptable to various dyeing processes, offering enterprises more flexible production options.

In terms of performance enhancement

SILIT-PUR5998N's results are particularly remarkable. After treatment with this improver, the wet rubbing fastness of dark fabrics can be significantly increased by more than 3 grades. For example, fabrics with an original wet rubbing fastness of 1 - 2 grades can reach 4 - 5 grades after using SILIT-PUR5998N, achieving industry-leading levels. At the same time, it effectively enhances color retention and reduces color fading, making the colors of dark fabrics more durable and vibrant, thus meeting consumers' demands for high-quality textiles.

SILIT-PUR5998N has a wide range of typical application scenarios, covering areas such as the post-finishing of black denim, high-density woven fabrics, and industrial dark textiles. During the post-finishing of black denim, it makes the color of denim more resistant, ensuring that the original color is maintained even after multiple washes and rubs. For high-density woven fabrics, it effectively solves the dyeing difficulties caused by their tight structure, improving fabric quality. In the field of industrial dark textiles, its stable performance and excellent fastness enhancement effect can meet the high requirements of the industrial sector for the durability and functionality of textiles.
