TECHNICAL INFORMATION
A reactive resin system with catalyst system integrated.
GENERAL PROPERTIES
- used for the resin finishing of woven and knitted cellulose fibres and their blends.
- applied by normal dry crosslinking methods on fabric and used for wrinkle free finishing of garments
- gives low formaldehyde levels on the treated fabric, meeting Öekotex Standard 100
- Single dose system, requiring no additional catalyst
- gives wash and wear effects durable to washing up to the boil
- compatible with most additives used in textile finishing
- is compatible with fluoro carbon resins
- gives excellent crease recovery and shrinkage control
- minimizes shade alterations
PHYSICAL PROPERTIES
| Appearance |
Light yellowish liquid |
| Chemical Constitution |
Modified dimethylol dihydorxy ethylene urea with a catalyst incorporated into the system |
| pH |
2.0 - 3.0 (± 0.5) |
| Density (20°C) |
1.27 ± 0.05 g/cm3 |
| Solubility |
Dilutable in cold water in all proportions |
| Storage |

SPECIAL ADVICE
- Ensure the fabric is well prepared, neutralised correctly and has not been treated with formaldehyde containing products such as cationic dye fixing agents in the preceding processes.
- For optimum results the resin should be applied at pH 4-5
PROCESSING
In order to achieve optimum curing the fabric should be fully absorbent and free of residual alkali from the pre-treatment stage. The amount of
Durapret LF Plus required is first diluted in water, the additives are added and then the bath is set to pH 4-5 and made up to final volume with
water.

The garments are treated either in an industrial washing machine at 30°C using a liquor ratio between 1:10 and 1:20 for 15-30 minutes followed by hydroextraction or by spray application. After tumble drying and pressing, the garments are cured at 150-155°C for 8-12 minutes in an oven.
