| Physical and Chemical Properties | Chemical quality This product is a white emulsion or viscous slurry. The freezing point is ≤ 0 and can be diluted with water in any proportion. Performance is lively. Can withstand hard water. When it reacts with the fiber, there is no acid precipitation, no brittleness to the fabric, and excellent washing and drying resistance. |
| Use | This product is used as cotton fabric, nitrile fiber and other soft treatment agent. It is also used as a resin finish for fabrics. Can increase the fabric fullness, softness and stain resistance. It is a commonly used softener. |
When using, gloves and protective glasses should be worn to avoid direct contact with the skin and eyes. If it gets on the skin, rinse with water and soap. Place in a cool and dry warehouse to prevent exposure to sunlight and rain.
1. Preparation of octadecyl ethylene urea
First, add 780 parts of water to the reaction kettle, freeze and cool to 0 ℃, add 27 parts of ethyleneimine, and drop 195 parts of octadecane isocyanate within 1-2 hours. The temperature will automatically rise during the reaction, but it should be controlled below 33~37 ℃. After dripping, keep it at this temperature for about 3 hours. Prepare octadecylvinylurea.
2. Emulsification
Add a small amount of fluorescent whitening agent and 9 portions of plain O to the prepared octadecyl ethylene urea, and quickly stir to form an emulsion. Adjust the pH value to 8 and then transfer it to a sanding mill for sanding. After grinding, discharge the material.
preparation of octaalkylethylene urea: 780 parts of water are added in the reaction kettle, frozen and cooled to 0 ℃, 27 parts of ethyleneimine are added, 195 parts of octaalkane isocyanate are added dropwise within 1~2h, and the temperature automatically rises during the reaction, but it should be controlled below 33~37 ℃. After dropping, keep the temperature at this temperature for about 3 hours. It is to produce decadyl vinyl urea.
Add a small amount of fluorescent whitening agent and 9 parts of flat plus O to the emulsified decadecyl vinyl urea, and quickly stir into emulsion. Adjust the pH value to 8 and then move into a sand mill for sanding. After grinding, discharge.
