Wet rubbing fastness enhancers are chemical additives used to improve the rubbing fastness of materials such as textiles and paper in a wet state. Rubbing fastness refers to the ability of a material to maintain its color, pattern or surface characteristics during friction. The main function of wet rubbing fastness enhancers is to enhance the wear resistance and color fastness of materials under wet conditions, and to prevent fading, dye transfer and other problems during washing, use or other wet environments.

 

These enhancers usually form a protective film or reinforced material structure by combining with fibers or coatings, thereby improving its stability in a wet state. They are widely used in the textile, printing and dyeing, coating and other industries to ensure the quality and durability of the final product during use.

 

Wear resistance

Wear resistance refers to the ability of a material to maintain its physical and chemical properties when subjected to external forces such as friction, abrasion or impact. Materials with good wear resistance can resist wear during use, extend their service life, and maintain their appearance and performance.

 

In industries such as textiles, coatings, and plastics, wear resistance is an important performance indicator. For example, clothing is subject to friction during wearing and washing, and fabrics with good wear resistance can reduce wear and tear and maintain their appearance and functionality. In industrial applications, wear resistance is also related to the efficiency and maintenance cost of equipment and tools.

 

Wear resistance is usually assessed through laboratory testing, such as standardized testing using a tribometer, to determine how a material resists wear under specific conditions.

 

Color fastness refers to the ability of dyes or pigments to maintain stable color on materials such as textiles and paper, especially the property that the color is not easy to fade or transfer when affected by external factors such as water, light, friction, washing, etc. The quality of color fastness directly affects the appearance and service life of the product.

 

Color fastness

 

Color fastness is usually assessed through a series of standardized tests, including:

 

 1. Washing fastness: Tests the ability of color to maintain during washing.

 2. Wet rubbing fastness: Tests the ability of color to remain when rubbed in a wet state.

 3. Light fastness: Tests the ability of color to maintain under light conditions.

 4. Dry rubbing fastness: Tests the ability of color to remain when rubbed in a dry state.

 

Color fastness is an important indicator of the quality of textiles, printed materials and other materials. Especially in clothing, household items and industrial products, good color fastness can ensure the beauty and durability of the products during use.

 

The application of wet rubbing fastness enhancer on denim is mainly reflected in the following aspects:

 

 1. Improve color fastness: Denim usually uses dark dyes, especially indigo dyes, which are easy to fade when wet. Wet friction fastness enhancers can enhance the color fastness of denim under wet friction conditions and reduce color transfer and fading during washing and wearing.

 

 2. Improve wear resistance: Denim is often used to make clothing, especially jeans, which are susceptible to friction and wear. By adding wet friction fastness enhancers, the wear resistance of denim can be improved, its service life can be extended, and the integrity of its appearance and structure can be maintained.

 

 3. Enhance washing performance: During the washing process, denim may be affected by water and detergent, resulting in color loss. Wet rubbing fastness enhancers can help denim maintain color stability during the washing process and reduce fading.

 

 4. Improve the feel and appearance: Certain wet friction fastness enhancers can also improve the feel of denim, making it softer while maintaining a good appearance, enhancing consumers' experience.

 

 5. Environmental protection: With the increasing awareness of environmental protection, many wet friction fastness enhancers are also being developed to reduce the impact on the environment while maintaining good performance.

 

In short, the application of wet friction fastness enhancers in denim can effectively improve its color fastness and abrasion resistance, improve washing performance, and thus improve the overall quality and market competitiveness of the product.

 

FOR example our product SILIT-PUR5998N

 

SILIT-PUR5998N is a deep improvement product, especially for treated fabrics that are difficult to improve their wet rubbing fastness. Its working fluid has good stability and high sustainability. It can solve the problem of oil slick and oil spots in the use of the same type of products. The improvement effect of wet rubbing fastness is obvious, and it can be increased to more than 3 levels.

 

 

The application of wet rubbing fastness improver on cotton cloth is mainly reflected in the following aspects:

 

 1. Improve color fastness: Cotton is often used to make various clothing and household items, especially dyed cotton. Wet rubbing fastness enhancers can enhance the color fastness of cotton in a wet state and reduce color fading and transfer when washed, worn or exposed to water.

 

 2. Improved wear resistance: Cotton fabrics are susceptible to friction in daily use, especially in high wear areas (such as elbows, knees, etc.). By adding wet friction fastness enhancers, the wear resistance of cotton fabrics can be improved, extending their service life and maintaining the integrity of their appearance and structure.

 

 3. Enhance washing performance: During the washing process, cotton fabrics may be affected by water and detergents, causing color loss. Wet rubbing fastness enhancers can help cotton fabrics maintain color stability during the washing process and reduce fading.

 

 4. Improve the feel and appearance: Certain wet rubbing fastness enhancers can also improve the feel of cotton cloth, making it softer while maintaining a good appearance, thus enhancing the consumer experience.

 

 5. Environmental protection: With the increasing awareness of environmental protection, many wet friction fastness enhancers are also being developed to reduce the impact on the environment while maintaining good performance.

 

In short, the application of wet rubbing fastness enhancers in cotton fabrics can effectively improve their color fastness and abrasion resistance, improve washing performance, and thus improve the overall quality and market competitiveness of the product.

 

For example our product SILIT-PUR5928

 

Wet fastness enhancer SILIT-PUR5928 is a polyurethane polymer, which can improve the friction fastness of active, direct, vulcanized and vat dyes on cotton fiber, especially for dark blue, black, big red, emerald blue wet fastness improvement effect is remarkable. When bathed with silicone oil, the wet fastness improvement effect is good.
