| What is "Liquid ammonia processing"? |
|
Mercerization is a method for processing cellulose fibers by alkalis. This processing makes the inside of the fibers swell to exploit new fiber properties beyond their original feel or physical properties. Sodium hydroxide (NaOH) and ammonia (NH3) are used as the alkaline chemicals for mercerization. |
| Type | Alkaline chemical | Feature |
|---|---|---|
| Normal mercerization | Sodium hydroxide | ·Enhanced luster ·Enhanced dyeing properties ·Enhanced tenacity ·Form stability |
| Low-temperature mercerization | Sodium hydroxide | ·Clear appearance ·Excellent luster ·Linen-like feel |
| High-temperature mercerization | Sodium hydroxide | ·Features better than those of normal mercerization ·Soft feel ·Crease resistant |
| Liquid ammonia mercerization | Ammonia | ·Soft feel ·Improved W & W properties ·Particularly effective for thick cloth |
| Dry mercerization | Sodium hydroxide | ·Exceedingly fine luster ·Excellent dyeing properties |

<Features of liquid ammonia processing> 1. This processing makes the inside of the fibers swell equally. 2. The fibers keep their soft feel as no damage is done by this processing. 3. Enhanced tear resistance 4. Excellent form stability (having good W & W properties with minimal shrinkage by washing) 5. This processing adds gentle, elegant luster to the fibers. 6. Highly uniform dyeing properties |
