      YI Hong, CAO Yuechan, LI Shuyang
      2025, 598(7): 22-27. https://doi.org/10.14162/j.cnki.11-4772/t.2025.07.008

      In order to conduct rapid and non-destructive quantitative detection and analysis of polyester fibers and regenerated cellulose fibers using near-infrared spectroscopy technology more effectively, this paper uses a grating scanning near-infrared spectrometer. A partial least squares (PLS) method combined with K-Fold cross - validation is adopted to establish a quantitative analysis model for blended fibers. 501 samples of polyester fiber blends containing viscose, modal, lyocell and cupro are used to construct an identification model and predict the fiber content. The results show that the correlation coefficient (R c) of the model reaches 0.9984, and the relative precision (RP) is 0.99824, both of which are close to 1, indicating a high-precision model.Meanwhile, the maximum absolute difference between the predicted content by the model and the measured value is less than 1%, and the prediction standard deviation is ≤0.6%. This model is expected to be used for the rapid detection of fiber content.

      Near-infrared (NIR) spectroscopy, with its advantages of rapidity, non-destructiveness, and simultaneous multicomponent analysis, has demonstrated significant potential in textile detection. This paper systematically reviews the principles and strengths of the technology, focusing on its application progress in fiber content determination and ecological safety testing (e.g., screening of banned azo dyes and formaldehyde content). Challenges such as model complexity, poor instrument universality,and high costs are analyzed. Future directions include enhancing spectrometer performance, integrating multi-spectral techniques,optimizing models, and reducing costs to promote broader application of the technology in textile detection.

      The purpose of this study was to explore the feasibility of rapid nondestructive identification of PET, PBT and PTT polyester fibers by near infrared spectroscopy combined with chemometrics. By collecting the near-infrared spectrum data of samples, the identification model was established by using algorithms such as similarity matching and discriminant analysis, and the spectral pre-processing (such as smoothing processing, baseline correction) and band selection strategies were optimized to significantly improve the prediction accuracy of the model. This method has the advantages of no sample pretreatment and high detection efficiency, and provides a new idea for online quality control of textiles.

      Student backpacks with reflective materials serve as a crucial safeguard for road safety. Currently, numerous student backpacks claiming reflective properties flood the market, yet research on their reflective performance remains limited, and relevant standards lack comprehensive evaluation criteria. This study simulates various scenarios encountered during daily backpack use to explore weather resistance and physical-mechanical durability treatments for reflective backpacks, while evaluating their retroreflective performance. Different styles and manufacturing processes of reflective student backpacks were selected for testing through simulated real-life usage scenarios. The research particularly focused on analyzing performance changes in reflective materials after environmental aging and drum abrasion tests. Results demonstrated that high-temperature and high-humidity environments exerted minimal impact on reflective material performance, whereas physical abrasion emerged as the primary factor causing performance degradation. This investigation provides a novel methodology for durability assessment of backpack reflective materials and holds practical significance for enhancing student traffic safety.

      Quantitative analysis of wool blended with other fibers in textiles commonly adopts the GB/T 2910.4—2022 Textiles— Quantitative Chemical Analysis—Part 4: Mixtures of Certain Protein Fibers with Certain Other Fibers (Hypochlorite Method), which primarily utilizes sodium hypochlorite solution at a concentration of 0.9~1.1 mol/L. However, long-term experimental observations have revealed significant drawbacks in this method: First, the sodium hypochlorite solution causes non-negligible damage to non-wool fibers during the dissolution process, leading to an overestimation of wool content as the mass of damaged fibers is erroneously attributed to wool. Second, the inherent instability of sodium hypochlorite requires frequent titration for concentration calibration, substantially increasing operational complexity. To address these issues, this study proposes the use of commercially available 84 disinfectant as a replacement for sodium hypochlorite solution. Experimental results demonstrate that this alternative method achieves complete dissolution of wool while maintaining stable data. Compared to the sodium hypochlorite method, the 84 disinfectant approach offers simpler preparation, greater operational convenience, and cost-effectiveness.

      Textile fibers are a crucial component of modern textiles. With the advancement of technology, their analysis methods have been widely applied in fields such as quality inspection, industrial production, forensic identification, and criminal investigation. Typical traditional analytical methods such as burning method, microscopic examination, and chemical dissolution method，have garnered widespread attention due to their capability for rapid qualitative analysis of fiber components. In recent years, as analysis techniques have continued to evolve and improve, modern analytical methods have been developed based on the distinct physical and chemical properties of textile fibers. These advancements have enhanced the accuracy of qualitative identification of fiber components and enabled precise quantitative analysis. This paper provides a detailed discussion of the principles, characteristics, and applications of both traditional and modern analysis methods. It systematically summarizes and compares the advantages and disadvantages of these approaches, offering a scientific and rational basis for selecting appropriate methods for fiber composition analysis

      To determine the residual amount of 2,4-diaminotoluene in textiles, an analytical method was established for the quantification of 2,4-diaminotoluene. Dichloromethane was used as the extraction solvent, and gas chromatography-mass spectrometry (GC-MS) was employed for the detection of 2,4-diaminotoluene residues in textiles. The method demonstrated excellent linearity (R²＞0.995), with a detection limit of 1.6 mg/kg and a quantification limit of 5 mg/kg. The recovery rate ranged from 89% to 93%, and the relative standard deviation (RSD ) for precision was 5.2%. Analysis of actual samples revealed that 9 out of 10 samples had 2,4-diaminotoluene residues below the quantification limit (5 mg/kg), complying with the requirements of GB 18401—2010. The results indicate that the method meets the criteria for precision and accuracy, exhibits good operability, and provides reliable reproducibility.

      A method for simultaneous determination of 6 kinds of isocyanates in polyurethane-coated textiles by HPLC/fluorescence detection was established. The 9-n-methylaminomethyl anthracene was isolated by Spursil C18 column, and then eluted with acetonitrile-3% triethylamine solution as mobile phase gradient. The fluorescence detector and external standard method were used for quantitative analysis. The effects of extractant, extraction times, derivatization time and volume of extractant on derivatization and separation of isocyanate were investigated. Under optimized experimental conditions, the linear correlation coefficients r of 6 isocyanates were in the linear range of 5 μg/L ~200 μg/L, the linear correlation coefficients r of 6 isocyanate derivatives were not less than 0.9990, the detection limits were in the range of 2.9 μg/L ~3.2 μg/L, and the quantification limits were in the range of 8.7 μg/L ~9.9 μg/L. The average recoveries were 90.52%~102.76% and the relative standard deviations (RSD, n=6) were 2.98%~7.83% at the concentration levels of 10 μg/L, 20 μg/L and 50 μg/L for blank samples. The method has high sensitivity, good repeatability and low limit of quantification, and is suitable for the determination of isocyanate residues in polyurethane-coated textiles.
