To evaluate the quality of detergents used in the conservation of historical textiles, laboratory samples are required. However, due to the unique characteristics of historical artifacts, existing standardized soiling methods are insufficient for researchers in this field. Therefore, this study aims to prepare artificially soiled cotton fabric samples subjected to accelerated aging. To achieve this goal, the type and amount of soiling were first determined, followed by monitoring and analyzing the degradation of samples during accelerated aging. The research methodology was based on analytical-comparative approaches, with data collected through experiments such as Fourier Transform Infrared (FTIR) spectroscopy, tensile strength testing, equilibrium moisture content, electrical conductivity, color measurement, and pH assessment. The procedure involved preparing, soiling, and aging cotton fabrics, with degradation changes monitored and compared to those of clean samples. Results indicate that after approximately 700 hours of accelerated aging under elevated temperature and humidity (110°C and 90% relative humidity), the samples reached a relatively stable state in terms of degradation changes. This stability allows minor adverse effects of detergents to be clearly detectable. Thus, the minimum time required for aging and preparing laboratory samples of soiled fabrics is approximately 700 hours at 110°C and 90% relative humidity.

Gradually, they became subject to modern concepts of preservation and restoration. Many methods used for centuries by traditional restorers in repairing and maintaining carpets were deemed unnecessary for treating museum carpets. Consequently, most treatment decisions, guided by the principles of minimal intervention and reversibility, became synonymous with various stabilization techniques. Given the historical background and role of traditional restoration in the process of preserving and restoring damaged carpets from the past to the present, this question arises: Can museum carpets be conserved without considering the positive potentials of traditional restoration? Answering this question has always been one of the most important debates between advocates of traditional and modern restoration in the conservation of carpets with museum value. Accordingly, this article aims to precisely understand traditional restoration, its goals and duties, as well as its place in the conservation of museum carpets. This research is applied and based on library studies, collection and examination of case studies through field methods, and personal experiences. The results indicate that techniques commonly used in traditional restoration can play a significant role in treating museum carpets and ensuring their preservation and longevity. Moreover, there is a continuous professional relationship between traditional restoration and conservation.  Traditional Restoration Modern Restoration Conservation Museum Carpets. 2020 1 01 13 24 http://journal.richt.ir/kcr/article-1-326-en.pdf

Addressing their functions, optimizing their design, and equipping them to ensure the proper preservation of objects, as well as preventing damage and deterioration, is of paramount importance. The significance of storage facilities lies in the fact that the majority of objects and artifacts within a collection are preserved in storage. Consequently, these spaces must meet high standards of conservation and security and require continuous care and monitoring.This article examines, as a pilot case, the textile repository of the Anthropological Research Institute, which houses a large volume of textiles belonging to diverse Iranian ethnic groups and cultures, representing a collection of exceptional value and importance. The current storage facility is unsuitable for the preservation of this collection and requires redesign and renovation in line with the specific vulnerabilities of textiles and international preventive conservation standards. The ultimate aim of this study is to improve the storage conditions of the ethnographic clothing collection through a newly designed system that complies with these standards.The research methodology relies on a review of library resources and the findings of similar projects. Although deterioration is inevitable, particularly in sensitive objects such as textiles, implementing appropriate storage strategies and environmental control systems can significantly prolong the lifespan of these invaluable objects and slow down the process of degradation.

Due to the use of this precious artistic artifact in the Astan Quds Razavi complex, over time and under various factors, it has sustained diverse damages. To preserve this valuable textile artifact, its restoration was carried out in the Textile Restoration Workshop of Astan Quds Razavi. This article, with a brief overview of the technology and pathology of the gold-embroidered curtain (Code 031), aims to examine the restoration methods applied to it based on field studies.

Following the establishment of the Chogha Zanbil Cultural Heritage Research Office in the museum—which had been closed during the eight-year imposed war—the organization of the remaining research objects, as well as the old documents, became a priority. This collection primarily includes administrative letters (in Persian and English), visitor statistics, letters of introduction, old object inventories, personnel files of former staff, and registers of correspondence and attendance. The existing documents, dating from 1970 to 1981, were kept under inadequate conditions. The collection was reviewed and systematically organized in two stages during 2001 and 2003, which is the focus of the present article. These documents are significant as they reflect aspects of the museum’s history and events. Due to the fragility and deterioration of many items, they were categorized, catalogued, and initially examined before being placed in transparent plastic covers and archived in corresponding binders. Additionally, digital scanning and the recording of important correspondence were undertaken as part of the organization process. These measures have facilitated a deeper study of the museum’s past, its collections, and the status of regional cultural heritage in the years preceding the revolution and the onset of the imposed war.

In 2017, 2019, and 2020, only one issue was published each year, while in 2018 no issue was released at all. These interruptions resulted in delays in the dissemination of submitted articles. To address these shortcomings, the decision was made in August 2024 to publish compensatory special issues. These special issues were prepared and released with the collaboration of invited guest editors and included a selection of outstanding papers presented at the 10th and 12th Conferences on Conservation and Restoration, along with newly submitted articles. Consequently, from August 2024 to September 2025, the backlog of delayed issues was resolved with the publication of a total of 31 issues, comprising 10 special issues and 21 regular issues. This initiative was undertaken to restore the trust of the scholarly community, disseminate postponed articles, and contribute to the advancement of knowledge in conservation and restoration.
