TECHNICAL INFORMATION
A newly developed reactive resin for easy-care finishes giving low formaldehyde levels and minimum loss of strength.
GENERAL PROPERTIES
- Used for the resin finishing of woven and knitted cellulose fibres and their blends.
- Applied by normal dry crosslinking methods on fabric.
- Has been specially modified to minimize the loss of strength.
- Gives low formaldehyde levels on the treated fabric.
- Gives wash and wear effects durable to washing up to the boil.
- Gives chlorine resistant finishing.
- Compatible with most additives used in textile finishing.
- Minimises tendency to yellowing.
- Gives excellent crease recovery and shrinkage control.
- Can be used with fluorochemical based water repellents.
- Thanks to its high reactivity, an increase of stenter frame speed is possible for approx. 10%
PHYSICAL PROPERTIES
| Appearance |
Yellowish liquid |
| Chemical Constitution |
Based on a modified dimethylol dihydroxy Ethylene urea |
| pH |
4.5 - 5.0 |
| Density (20°C) |
1.20 ± 0.05 g/cm3 |
| Solubility |

PROCESSING
In order to achieve optimum curing the fabric should be hydrophilic and free of residual
alkali. The amount of Durapret 100 required is first diluted in water, the additives followed by the prediluted catalyst are added and then the bath is set to pH 4-5 and made up to final volume with water.
