# Investigating the Degradation of Historical Man‐Made Cellulose‐Derived Textiles via Accelerated Ageing

## TL;DR

This study explores how historical cellulose-based textiles degrade over time using accelerated aging to identify signs of decay and improve preservation methods.

## Contribution

The study introduces new insights into degradation markers for man-made cellulose fibers in museum collections.

## Key findings

- Surface morphology changes, mass loss, and discoloration are identified as physical degradation markers.
- Spectral band shifts indicate chemical changes during degradation of cellulose-derived textiles.
- Findings can guide conservation strategies for preserving historical cellulose-based materials.

## Abstract

Cellulose‐derived materials, like paper and cellulose acetate, are known to be vulnerable to degradation within museum collections. Studies have been conducted and degradation markers have been identified on these materials. However, the degradation of man‐made cellulose‐derived fibers in collections is not well understood. This study aims to provide insights into historical cellulose acetate and regenerated cellulose textiles to quantify their physical and chemical changes during degradation using accelerated ageing experiments. Potential physical and chemical markers for degradation are identified, including changes in surface morphology, mass loss, discoloration and changes in spectral bands. These markers can be used to improve understanding of the degradation mechanisms of historical cellulose acetate and regenerated cellulose textiles and guide the development of conservation strategies. These findings have important implications for understanding the stability of man‐made cellulosic fibers in museum collections.

Cellulose‐derived materials, such as paper and cellulose acetate, degrade in museum collections. The degradation of man‐made cellulose fibers remains poorly understood. This study examines historical cellulose acetate and regenerated cellulose textiles using accelerated ageing. Identified markers, for instance surface changes, mass loss, discoloration, and spectral shifts, provide enhanced understanding of degradation behavior and inform conservation and preservation strategies.© 2025 WILEY‐VCH GmbH
