Biobased lubricant microcapsules and complexants for textile preservation
Innovative biobased solutions for textile preservation utilizing lubricant-filled microcapsules to reduce fiber friction and biodegradable complexants to enhance dye fixation and absorption, aiming for improved wear resistance and sustainability.
Overview
This research introduces advanced biobased solutions designed to enhance textile preservation. The core innovation involves integrating lubricant-filled microcapsules into textiles to significantly reduce friction both between fibers and on textile surfaces, thereby extending the longevity and wear resistance of fabrics. Additionally, biobased polymers modified with cationic and zwitterionic groups are proposed as sustainable alternatives to traditional PVP-based solutions. These polymers can either seal dyes to prevent their release or absorb dyes during washing, offering a biodegradable option compared to existing solutions.
