Color Fastness to Wet Friction

Promoter for Reactive Dyes

HOLPOSON® Color Keep-Rub

Color Keep-Rub is a color fastness to wet friction improver developed by our company. It’s suitable for improving the color fastness to friction of textiles made of cotton and cellulosic fibers, which are dyed with reactive, direct, reductive and sulfurized dyes. It is especially suitable for improving the fastness of black, bright red and other colors.

Physical & chemical properties:             

Appearance:            Light yellow liquid

Ionicity:                 Weak cationic

pH:                     Acidic

Solubility:               Easily dilutable in cold water

Usage:

1. Padding

Color Keep-Rub:           20~30g/L

Dispersing chelator:        0.5g/L (for stability)

Acetic acid adjustment:     pH = 5

Processing method: Dip and roll (liquid content: 70%), bake at 150℃ for 60 - 90 seconds after drying

2. Impregnation process

Color Keep-Rub:            2~5g/L

Processing method: Impregnate at 30-40℃ for 5-10 minutes, dehydrate and dry.

Characteristics:

1. Significantly improves the color fastness to wet friction of materials dyed with reactive, direct, sulfurized and reduced dyes.

2. It hardly affects the luster and hand feeling of the dyed material.

3. It has good stability and is suitable for impregnation treatment of knitted fabric and finished garment.

Attentions:

Please control the concentration of the solution below 30g/L, dilute it with cold water with a temperature of no more than 35 ℃.

Before treatment, the material must be fully washed to remove flooding, and adjust by neutralization the pH value of fabric surface to neutral - weak acidic.

Due to different dyeing equipment, the operation stability will be affected by possible shortage of working solution in the process, so it is necessary to ensure the product stability through preliminary tests before use.

This product is weak cationic, and its stability will be affected by factors like hardness of water used in dyeing, metal ions, acids, alkalis, salts, etc. Please do confirm the product’s compatibility with other agents used in the same bath through sample tests.

Storage:

1. Keep indoor

2. Avoid overheat and severe cold
