| Name | softener HC-39 |
| Synonyms | softener HC-39 |
| PH | 7~9 |
| Physical and Chemical Properties | Chemical properties The appearance of this product is a white thick emulsion, which can diffuse in water and is cationic. Slightly acidic. This product is extremely sensitive to carbonic acid, alkali and sulfate. Sharing with sodium sulfate produces precipitation, which cannot be shared with anionic surfactants. |
| Use | Uses for cotton, hemp, rayon, nylon and other softeners. Mainly used for elastic nylon yarn dyeing soft treatment agent. |
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. Heat and melt 130 parts of stearamide in an enamel kettle. Add 49.4 parts of 37% formaldehyde solution and 12 parts of 50% liquid alkali, stir well, reflux for 1 hour, and complete the hydroxymethylation reaction.
2. Pour 2 portions of the mixture into a dissolution tank, then dissolve and add the above reactants at room temperature. Stir vigorously to emulsify into a slurry. Grind the sand in the sanding machine, and finally filter the finished product.
90 parts of N,N-dimethyldecaoctaamine, 51 parts of stearic acid, 106 parts of paraffin wax and 5 parts of flat are successively put into enamel kettle, 53 parts of acetic acid are added under stirring after heating and melting, and the temperature is raised to 90 ℃. Add boiling water and quickly stir to emulsify the mixture. The pH value is adjusted to 3~5. Heat preservation for another 1 h, cooling and discharging to obtain the finished product. During the mixing process, amines and acids form quaternary ammonium salts.
