| Name | Mercerizing Penetrant DP |
| Synonyms | silkete penetrating agent DP |
| PH | 7.0~9.0 |
| Physical and Chemical Properties | Brown or light yellow liquid, easily soluble in water and ethanol, belongs to the category of cationic surfactants. Strong permeability in 10% alkaline solution. |
| Use | Used for mercerizing cotton and polyester/cotton fabrics, it can shorten processing time, reduce alkali content, improve mercerizing effect, and increase fabric strength. |
Store in a dry, cool, and ventilated warehouse.
Add ethylene glycol butyl ether to the reaction kettle, raise the temperature to 40 ℃ under stirring, add 0.2%~0.3% phosphite (mixed into 50% aqueous solution), then add P2O5, and stir at 70-80 ℃ for 4 hours after adding. Cool to 40 ℃ and adjust the pH value to (1% aqueous solution) using NaOH aqueous solution 7.0~9.0. Add a small amount of hydrogen peroxide for decolorization, and use a 100 mesh sieve while hot to remove impurities. Produce finished products through discharge.
