TL;DR
This paper introduces a sustainable method using dopamine and silk sericin to reduce pilling in wool fabrics without harming their structure.
Contribution
A novel synergistic treatment using dopamine and silk sericin to enhance wool fabric anti-pilling properties sustainably.
Findings
Optimal treatment conditions achieved a pilling grade of 5 with minimal structural damage.
Modified fabrics showed improved heat retention and moisture permeability.
The cross-linking process had a low activation energy of 30.8 kJ mol−1.
Abstract
Pilling of wool knitted fabrics during wearing or washing has long been a persistent and challenging issue. Conventionally, most anti-pilling treatments are either environmentally unfriendly or cause substantial damage to the internal structure of wool. This study adopts dopamine cross-linking silk sericin to modify wool knitted fabrics. The effects of dopamine concentration, silk sericin concentration, and cross-linking reaction time on wool fiber scale parameters (fiber friction coefficient, crimp ratio, and crimp recovery rate), anti-pilling properties, air and moisture permeability, heat retention, and mechanical properties of wool knitted fabrics were investigated. Based on the synergistic effect between dopamine and silk sericin, the wool scales were effectively encapsulated, thereby reducing the directional friction effect. Optimal conditions were identified as 1 mg mL−1…
