      Abstract ( )   Knowledge map   Save
      This study organized an interlaboratory comparison test involving 18 laboratories to analyze the discrepancies in textile lightfastness test results. Preliminary analysis indicated that differences in effective humidity control might be the primary cause for the inconsistency. To investigate this, targeted verification experiments on key influencing factors (effective humidity, endpoint determination, and personnel visual assessment variation) were conducted in the laboratory. Results showed that for humidity-sensitive samples, variations in effective humidity control significantly affected the test results, with differences reaching up to 2.5 grades. The variations in endpoint determination and personnel visual assessment typically had a controlled impact of ≤0.5 grade on the average result, but could influence the judgment for borderline samples. The verification tests elucidated the mechanisms by which these key factors affect the measurement results, providing technical support for enhancing the consistency of interlaboratory test results.

      Abstract ( )   Knowledge map   Save
      To more realistically simulate the pilling phenomenon of wool woven fabrics during actual wear, this paper proposes a new pilling test method for worsted woven fabrics, namely the self-grinding method, by comparing and analyzing the limitations of four existing domestic test methods for fuzzing and pilling. Using the fabric sample itself as the abrasive, this method specifies key parameters such as friction pressure and friction cycles, enabling more accurate simulation of pilling behavior in high-frequency friction areas of garments (e.g., armpits and crotches). Test results show that the correlation between the test results of the self-grinding method and actual wear effects is significantly better than the circular track method and are more consistent with the actual wear status, providing more scientific technical support for the quality control of wool woven fabrics.

      Abstract ( )   Knowledge map   Save
      In the metrological inspection of the net content of prepackaged goods, the evaluation of measurement uncertainty is a critical step in ensuring the accuracy and reliability of inspection results. Based on the fundamental framework of the Guide to the Expression of Uncertainty in Measurement (GUM), the evaluation typically adopts a combined Type A and Type B assessment method to systematically identify and quantify uncertainty components arising from various sources, including measuring equipment, environmental conditions, operating procedures, and personnel skills. However, current evaluation practices face problems such as incomplete identification of uncertainty sources, unscientific quantification of components, insufficient professional competence of inspection personnel, non-standard management of instruments and equipment, and a lack of unified standards for the evaluation process, all of which hinder the improvement of evaluation quality. To address these issues, strategies such as improving the evaluation system, standardizing the component quantification procedure, strengthening personnel training and assessment, strictly enforcing full life-cycle management of instruments and equipment, and optimizing inspection workflows can systematically reduce the influence of uncertainty and enhance the scientific rigor and impartiality of net content inspection work.

      Abstract ( )   Knowledge map   Save
      Quality inspection of cotton textile products runs through the whole process of spinning production. The traditional management mode has pain points such as data silos, information lag and difficult traceability. With the deep integration of information technology and manufacturing industry, building an integrated quality inspection information management platform has become a key approach to improving quality control. At present, the informatization of quality inspection in the cotton textile industry presents a polarized feature: leading enterprises have taken the lead in deploying intelligent systems, while small, medium and micro enterprises still rely on manual operations, generally facing challenges such as poor system adaptability, low data integration and shortage of talents. Promoting information-based management can significantly improve quality inspection efficiency, ensure data accuracy, establish a full-chain traceability system, enable scientific decision-making and meet regulatory requirements. The implementation path should be steadily promoted in four stages: preparation and planning, pilot implementation, comprehensive promotion and optimization and upgrading. Meanwhile, the construction of a compound talent team should be strengthened, and solid support should be provided from technical and financial aspects, helping enterprises realize the transformation and upgrading of quality management from passive post-remediation to active pre-prevention.

      To address the issues of imperfect metrological traceability and inconsistent uncertainty evaluation in the field calibration of industrial gas online metering devices, a measurement model centered on mass flow rate and indication error is constructed, and field calibration approaches for differential pressure, velocity, and ultrasonic flowmeters are proposed. In accordance with JJF 1059.1—2012, an uncertainty component system is established, and the combined and expanded uncertainties are calculated at different flow points. The results show that all expanded uncertainties are less than 1.24%, which meets industrial metrology requirements, thus forming a standardized methodological framework for online calibration and uncertainty evaluation.
