With the growing emphasis on sustainable development and the circular economy in the textile industry, recycled wool fiber has emerged as a crucial form of resource recycling, with its market demand continuously increasing. However, challenges remain in quality consistency, hygiene, and safety due to diverse raw material sources and non-uniform production processes. This study aims to systematically evaluate the comprehensive quality characteristics of recycled wool fiber products, identify potential risk points, and provide scientific evidence for enhancing their safety and functionality. Employing a sampling methodology, 40 batches of recycled wool fiber samples were collected from the market. In accordance with relevant standards, analyses were conducted across four dimensions: fiber composition, physical properties, chemical characteristics, and microbiological safety. Key findings include: Significant variation in wool content (20%~100%),with high-wool samples (>80%) being more prevalent, enhancing warmth and skin-friendliness; polyester content (1.5%~67.4%) negatively correlated with wool, indicating adjustable blending ratios, yet volatile impurity fibers (2.0%~11.7%) revealed raw material complexity. Physically, moisture regain (11%~15% in high-wool samples) requires control to prevent mildew or brittleness; impurity rates were generally acceptable (65% of samples ≤2.0%), but outliers (e.g., 4.3%) necessitate improved cleaning processes. Chemically, dichloromethane-soluble substances (67.5% meeting premium-grade standards) complied with national standards. However, microbiological testing detected Pseudomonas aeruginosa in Sample #١٩, violating GB ١٨٣٨٣—2007 hygiene requirements and highlighting contamination risks in recycling/storage. The industry must optimize raw material sorting, blending design, and sterilization to balance sustainability with quality safety.

Based on the framework of GB/T 32008—2015 standard, this study selected 12 samples with actual dye migration issues during storage or transportation. The temperature effects on dye migration under constant humidity (80% RH) were systematically analyzed through a gradient temperature control testing system. Comparative tests were conducted between standard conditions (24 ℃/48 h, 38 ℃/4 h, 70 ℃/3 h) and newly added conditions (50 ℃/4 h, 60 ℃/4 h). Results showed that although test conditions (24 ℃/48 h, 38 ℃/4 h) met standard requirements (≥Grade 3~4), they failed to prevent color migration risks during storage and transportation. When temperature reached 60 ℃, the qualification rate of colorfastness to storage decreased dramatically, and further dropped to 8.3% under 70 ℃/3 h testing. It is recommended that enterprises select appropriate test conditions according to regional climatic characteristics, providing reference for risk classification and control in textile storage and transportation.

The national standard method for quantitative chemical analysis of blended fabrics, while accurate and reliable, suffers from time-consuming and operationally cumbersome bottlenecks in its drying and filtration steps. To improve detection efficiency, this study aims to optimize these two critical steps of the standard method. By replacing the air-oven dryer with a halogen moisture analyzer for drying and innovatively adopting a stainless steel mesh filtration system instead of sintered glass crucibles, an integrated rapid analysis workflow was established. Using five typical two-component blended fabrics, a comparative study was conducted between the optimized protocol and the standard method. The results showed no significant difference between the optimized and standard methods (p > 0.05), with all absolute component differences (0.03%~0.57%) below the standard tolerance limit (≤1%). Furthermore, the analysis time was reduced from over 12 h to within 30 min. This optimized approach significantly enhances analytical efficiency while ensuring accuracy, providing a reliable new solution for routine rapid testing in laboratory settings.

Against the backdrop of intensifying international trade frictions, the operational performance of textile enterprises faces severe challenges, necessitating digital transformation as a pathway to sustainable development. However, the mechanisms through which digital transformation impacts enterprise performance remain underexplored. This study empirically examines the effects of digital transformation on the operational performance of Chinese A-share listed textile enterprises using unbalanced panel data from 2009 to 2022. The findings reveal that digital transformation exerts a positive influence on both short-term and long-term operational performance. Mechanism analysis demonstrates that economies of scale effects, risk mitigation effects, and human capital optimization effects serve as core transmission channels. Heterogeneity analysis further indicates that the performance-enhancing effects of digital transformation are more pronounced for non-state-owned enterprises, smaller-scale firms, and enterprises operating in regions with heightened competitive intensity.
