Disperse stain remover for polyurethane
Bisnol UP-10
Polyurethane, popular due to its high performance as a stretch back material, is used widely in blends with other fibers to produce high-performance materials. However, in polyester/urethane blends, staining of urethane by disperse dyestuffs is very difficult to remove. Agents used to remove stains are not very effective and can adversely affect various color fastnesses.
Bisnol UP-10, developed and sold by Ipposha Oil Industries, is a stain-removing agent for disperse dyestuffs on urethane for which the main component is a special surfactant of high molecular weight. Due to its excellent affinity for dyestuff and its solubilizing strength, it effectively removes staining by disperse dyestuffs and contributes to the enhancement of various color fastnesses.

Attributes of the water quality
Properties
- Excellent dyestuff affinity and solubilizing strength; effectively removes the stains of disperse dyestuff from urethane.
- Contributes to the improvement of various kinds of colorfastness, eg. colorfastness to rubbing with solvent, to washing, and to dry cleaning.
- Very little staining by the solution during testing for colorfastness to washing and to dry cleaning; effective in both the removal of stains and in the prevention of redepositon.
- Does not negatively affect urethane fibers.
- Effectively removes stains when used alone and in acidic conditions.
- Low foaming

1. Test for colorfastness to washing
2. Test for colorfastness to dry cleaning
Method of use
While the amount used varies according to the dyestuff and the dyeing method, a general range is 1.0~3.0 g/L.
In dyeing, use 1.0~2.0g/L of Resistol UD-7, an anti-staining agent for urethane with disperse dyes, to limit staining caused by disperse dyestuffs and to improve colorfastness.
