SPECIALITY POLYESTER RESIN FOR ZERO TWIST FILAMENT YARN SIZING
| R-3000-NAJ is a New Generation Polymer designed for Zero Twist Filament Yarn Sizing. It replaces Acrylic Polymer solution.R-3000-NAJ reduces the percentages of size add-on to 3.5 – 7%, depending on the yarn and the type of looms with exceptionally good weaving performance.
R-3000-NAJ is a 100% solid resin product available in granular form. It dissolves easily in hot water and hence very easy for desizing. |

A typical recipe to size polyester filament yarns is as follows:
| R-3000-NAJ |
10kg. |
Water (demineralized water or soft water,
total dissolved solids of soft water should be low) |
90 kg. |
| Total weight |
100 kg. |
| Note : Solid content of recipe is:
Solid x 100
Total Weight |
10% |
- Take 70% of the total water used in the recipe. Start heating and bring it close to boiling.
- Addition of R-3000-NAJ should be spread over 20-30 minutes, after the temp. has reached 90°C. This ensures easy solubilization. Do not add all the powder at one time.
- Heat further for 1 to 2 hours to dissolve R-3000-NAJ completely.
- Part of the water which evaporated during heating should be replaced by adding equivalent amount of water.
- Also add the remaining 30% of the water. This addition of water will bring down the temperature to 50-55°C.
- Allow it to cool to 30-35°C and then start sizing.
- One can use lubricants & antistatic additives.
|
The size add-on expected with normal machine conditions is between 4 to 4.5%. One may change the level of water, depending on wet pick-up, to maintain final size add-on between 3.5 to 7% as per needs. |
- Keep the bags of R-3000-NAJ in cool shade. Do not keep it in hot Sun or at a temperature higher than 40°C.
- In case the bags are open and are intended to be stored for a longer time, ensure to tie and seal the mouth to avoid moisture contact.
