The detection of color fastness to rubbing is the basic assessment index for textile color fastness. Enhancing the rubbing color fastness of textiles is the key to improving the quality of fabric products. In the improvement of dry wet rubbing fastness of textiles, the use of appropriate special additives (such as T-52/T-55 dry wet rubbing fastness improver) can effectively improve the rubbing color fastness of dyed fabrics.

    The T series of dry wet friction fastness improvers has the following characteristics:

    1. The dry wet friction fastness enhancing agent has high stability and good temperature and electrolyte resistance, which can meet the requirements of long-term continuous operation. The wet friction fastness of fabrics dyed with reactive, direct, sulfurized, and indigo dyes can be improved by 1-2 levels.

    2. The working fluid of the dry wet friction fastness enhancing agent is stable, with good temperature resistance and electrolyte resistance;

    3. The dry wet friction fastness enhancing agent acts on dyes and fibers through cross-linking and film forming coating, which significantly improves the fastness and has little impact on hand feel and color light, and does not damage other fastness of dyed fabrics;

    4. Used for improving the fastness of denim fabrics, it can meet the low-temperature cross-linking requirements of washing plants.
