Wet rubbing fastness is a key quality indicator for denim fabrics. This is especially true for deep shades.It also applies to denim with special finishes.For example, enzyme wash or snow wash.

Rubbing happens with moisture.
Water or sweat create that moisture.Poor fastness leads to heavy color fading and staining during wear or washing. It ruins the look and can dirty other clothes.
A Solution Built for Denim
TEXNOLOGY®R280 wet rubbing fastness improver is a water-based polyester polymer. It is designed to boost wet rubbing fastness and wash fastness on fabrics. How does it work?
It forms a clear, colorless, and strong film on the fiber surface. This film wraps and bonds dye particles firmly inside the fiber. As a result, dyes are locked in place. Dye transfer caused by rubbing is greatly reduced.
Four Core Advantages
- Eco‑safe and meets global standards
TEXNOLOGY®R280 wet rubbing fastness improver contains no free formaldehyde. It meets the basic ecological requirements for modern textiles. Denim brands can easily comply with international rules like OEKO-TEX. - Strong bonding with anionic dyes
