Summary
A new reactive nonionic softener (RNS) improves crossbred wool fabric
Area of Science:
- Textile Chemistry
- Materials Science
- Surface Science
Background:
- Crossbred wool fabric exhibits higher surface roughness compared to Merino wool.
- Improving the functional properties of crossbred wool is crucial for textile applications.
Purpose of the Study:
- To develop a reactive nonionic softener (RNS) for crossbred wool fabric.
- To impart multi-functional properties including smoothness, wettability, and felting resistance.
Main Methods:
- Treatment of wool fabric with a fatty acid (FA) and 2-amino-2-methyl propane diol (AMPD) based RNS.
- Application via pad-dry-cure method with varying RNS concentrations, curing temperatures, and durations.
- Analysis using FTIR spectroscopy and scanning electron microscopy (SEM).
Main Results:
- Optimal treatment conditions: 3.5% RNS, 130 °C, 5 min, yielding a 21.7% increase in surface smoothness and 90% increase in felting shrinkage resistance.
- Treated fabric maintained air permeability and dyeability.
- Smoothness durability confirmed up to 5 wash cycles.
Conclusions:
- The developed RNS effectively enhances crossbred wool fabric properties.
- The treatment offers durable smoothness and improved functional characteristics.
- RNS shows potential for industrial application in wool finishing.
