(2025-2026) is an interdisciplinary research initiative dedicated to the conservation of thermoplastic polyurethane (TPU) coated fabrics in fashion and design collections with blooming. Since the 1960s, TPU has been widely used in textiles, from glossy and metallic finishes to waterproof, leather-like and technical fabrics. However, these materials face a critical conservation challenge: blooming - a degradation phenomenon that manifests as white crystalline deposits on the surface, altering aesthetics and material integrity. Bringing together scientists, conservators, curators, and industry experts, InBloom explores the causes of blooming, its impact on heritage collections, and effective conservation strategies.

The project combines advanced chemical analysis, historical research, and conservation practice to develop guidelines that support museum professionals in preserving TPU-based objects for future generations. 

Supported by the Portuguese Foundation for Science and Technology (FCT) MCTES through the funding grant 2023.11375.PEX (https://doi.org/10.54499/2023.11375.PEX), this 18-month initiative builds on the previous work conducted in the Glossy Surfaces Project (2020–2023). The project identified blooming as an urgent form of damage, highlighting the need for further research and conservation strategies.
