This paper discusses the application of information technology in the notarial inspection of quality of Xinjiang regulated cotton (hereinafter referred to as "notarial inspection of Xinjiang regulated cotton"). The workload of notarial inspection of Xinjiang regulated cotton is huge. Traditional manual operations are prone to data errors or sample damage due to factors such as clerical errors and weather, which affect the efficiency and accuracy of inspection. To this end, Sichuan Fiber Inspection Bureau has jointly developed a smart supervision system for cotton warehouses, which solves the above problems through mobile and intelligent management methods.

To address the persistent challenges of paper-based routing slips in cotton quality notarized testing—namely, cumbersome manual data entry, slow document circulation, high susceptibility to information errors, and inadequate process traceability—this study investigates the implementation of an electronic routing slip system tailored to the operational requirements of testing laboratories. The electronic system covers the entire testing workflow, including sample collection and delivery, sensory evaluation, moisture regain testing, sample conditioning, High Volume Instrument (HVI) analysis, and retained sample management. Structured around a unique sample identification code, the system integrates bar-code recognition, mobile terminal data entry, automatic uploading of instrument measurements, electronic signatures, and system logging for comprehensive audit trails. This design enables online transmission of inspection data and full life-cycle traceability of all procedural steps. Practical application demonstrates that, compared with the paper-based counterpart, the electronic routing slip system substantially reduces manual transcription and physical document transfer, improves workflow efficiency and data consistency, standardizes sample handover procedures, and strengthens process supervision and accountability. This digital solution aligns well with the growing demands for standardization and informatization in cotton quality notarized testing, and serves as a reference for fiber quality monitoring agencies pursuing paperless operations.

In-warehouse weight official classification of cotton is a core technical means to ensure fairness in cotton transactions and a key link in standardizing the cotton market order. This article systematically analyzes critical issues in in-warehouse official classification of cotton, such as delays in detecting abnormal weighing results, inadequate supervision of moisture regain testing, and limited methods for reviewing impurity content test data. It proposes refined control strategies, including establishing a dynamic "tabular deviation verification" system for weighing, creating a quality control system for moisture regain testing that combines "equipment assurance and dual-role verification", and implementing an optimized impurity content testing scheme based on "scientific sampling and dual-review". These strategies aim to enhance the accuracy, reliability, and credibility of inspection and testing data by strengthening process monitoring and introducing cross-verification and error correction mechanisms, thereby providing technical and managerial support for the high-quality development of the cotton industry.

To address practical issues in fiber quantification of modal/nylon/spandex three-component blended fabrics, such as the lack of a unified preferred method, large deviations in detection results, and poor reproducibility, and to improve the accuracy and stability of fiber content detection in multi-component textiles, this study takes two types of blended fabrics with different colors as research objects. Twelve combinations of chemical dissolution and manual separation quantitative schemes were designed. Through fiber damage coefficient testing, parallel determination of multiple schemes, reproducibility verification with quality control samples, and single-sample t-test statistical analysis, the effects of different dissolution sequences, reagent types, and temperature conditions on detection results were systematically compared. The results show that a two-step selective chemical dissolution method achieves the optimal detection effect: first, selectively dissolve nylon with 80% formic acid solution at room temperature, then dissolve modal with 20% hydrochloric acid solution at 70 ℃, leaving spandex as the insoluble residue, and calculate the content of each component using the mass difference method. This method is not affected by fabric color, has strong dissolution selectivity, does not cause additional fiber damage, provides stable measurement data, high precision, and excellent reproducibility. All indicators meet the routine testing and quality control needs of manufacturing enterprises, providing a standardized and replicable detection procedure for fiber quantification in three-component blended fabrics.

The accuracy and consistency of detection data generated by the High Volume Instrument (HVI) for high-capacity cotton fiber testing serve as the critical prerequisite for ensuring fair transactions in the cotton market. Conducting inter-laboratory consistency comparisons of test results among different official classification laboratories constitutes an essential approach to verifying the accuracy and consistency of HVI test outcomes, and plays a pivotal role in the quality control of such laboratories. Drawing upon the results of HVI comparison experiments carried out by the Tumushuke Laboratory and the Bachu Laboratory, this paper analyzes the factors influencing the conformity rate of inspection indicators and the heterogeneity of test results across different laboratories, thereby providing more targeted practical guidance for the consistency control of HVI test results in cotton public inspection laboratories.

At present, domestic and international standards for color fastness to light of textiles usually adopt carbon arc lamps, xenon arc lamps and other light sources to simulate ordinary lighting environments, which cannot accurately evaluate the fading and discoloration of textiles caused by LED spotlights in commercial display scenarios, and may easily lead to risks in enterprise quality control and consumer rights protection. In order to establish a test method suitable for evaluating textile discoloration in actual display environments, this paper systematically investigated the effects of three key parameters of LED spotlights-power, beam angle and color temperature-on the color fastness of textiles to spotlights by using a spotlight color fastness tester, optimized the test parameters, and verified the effectiveness of the method with samples that had discolored during actual display. The results show that 5 days of testing under the conditions of 40 W/6000 K/24°can accurately evaluate the discoloration of textiles in display.

Cotton official classification laboratory is the main work place for the worker; it has a direct bearing on the occupational health of inspectors and the quality of inspection work. Currently, most cotton notarized inspection laboratories in China face significant environmental hazards; the sealed nature of constant temperature and humidity rooms and grading rooms leads to poor ventilation, compounded by dust and noise pollution, which seriously damages the physical and mental health of inspectors and hinders the standardized conduct of inspection work. Combining the actual operational status of laboratories, this paper identifies core environmental issues, analyzes their causes and negative impacts, and proposes actionable measures such as ventilation optimization, dust control, and noise prevention. It provides practical references for improving laboratory operational quality, safeguarding inspectors’ occupational health, and promoting the standardized construction of the cotton inspection system, thereby facilitating the high-quality development of the cotton industry.

In the testing of multi-color school uniforms, defining the test scope is the key challenge in contract review process. Based on the conflict between standard's color-separate requirements and limited sample area, this paper proposes a contract review strategy aimed at ensuring garment testing integrity. Principal component analysis of colorfastness reveals three components: perspiration, friction, and washing—guiding test items selection. To address limited sample area, four prioritized principles are established: safety items first, dominant colors first, tiered testing first, and supplementary sampling first. Along with conflict resolution rules. A 15% area threshold from GB/T 29862—2013 is adopted to distinguish dominant from accent colors. On this basis, it summarizes contract review strategies for supervision and commissioned testing, and a Completeness Checklist for Multicolor Uniform Testing is designed to support decision-making when samples are insufficient.

A method for the determination of dimethyl fumarate (DMFu) and dimethyl maleate (DMMA) in leather by gas chromatography-mass spectrometry coupled with internal standard method (GC-MS-IS) was established, with the optimization of sample pretreatment and chromatographic parameters. Ethyl acetate was used as the extraction solvent for ultrasonic extraction at 50 ℃ for 50 minutes.

This research provides a practical technical support for the digital, compliant and intelligent transformation of textile laboratories, and also provides a reference for the intelligent compliance management of laboratories in other professional fields.

Given the time-sensitive requirements for batch release judgment in spandex production, this study developed a rapid on-site detection method for dimethylformamide (DMF) residue. The approach includes pretreatment with ethanol extraction and disposable filtration, a p-dimethylaminobenzaldehyde colorimetric system, and a colorimetry module with LED light source and photodiode. The device dimensions are controlled at 20 cm×15 cm×10 cm, with a weight under 1 kg. Method validation was conducted using gas chromatography as reference, achieving a detection limit of 0.5 mg/kg and a quantification limit of 1.0 mg/kg. Fiber spiked recovery rates ranged from 85% to 95%, with relative standard deviations below 5%. The method was implemented in batches on a production line, reducing on-site testing time by 80% compared to traditional gas chromatography (average 15 minutes per batch), enabling rapid intra-shift release with a compliance rate of 98%. Results demonstrate that this on-site technology effectively couples quantitative measurement with quality release, enhancing production efficiency and providing actionable metrological support for timely process window convergence in workshops.

On June 1, 2026, the State Administration for Market Regulation implemented the "One List, One Database" management for qualification accreditation of inspection and testing institutions nationwide, marking a fundamental shift in China's inspection and testing market access system from decentralized approval to national unification. From the perspective of institutional change, this paper systematically analyzes the multi-dimensional social impacts of this policy on the inspection and testing industry. The findings reveal that the policy promotes a fundamental shift in the industry's competitive logic from "qualification competition" to "capability competition" through unified licensing boundaries and standard systems, triggering structural consolidation; effectively curbs out-of-scope operations and report fraud while eliminating hidden barriers in bidding processes; breaks down local protectionism and market segmentation; and reserves development space for strategic emerging industries through the "sandbox regulation" mechanism. The deeper value of this policy lies in the redefinition of the government-market relationship through institutionalized boundary demarcation, providing a replicable institutional paradigm for the regulation of the inspection and testing industry.

The lifecycle management of pressure gauges encompasses precise selection, standardized installation, periodic verification, in-service monitoring, fault early warning, rapid replacement, data traceability, and scrapping and recycling, exerting a dual impact on enterprise production safety and efficiency. To optimize the effectiveness of pressure gauge lifecycle management, it is necessary to establish graded selection criteria based on process hazard levels, dynamic verification intervals and online comparison systems, rapid fault response mechanisms, and a spare parts standardization system, as well as to build a lifecycle information platform and environmentally sound scrapping processes. Systematic pressure gauge management constitutes a key pathway to enhancing both production safety and operational efficiency.

In response to the nonlinear and time-varying errors caused by scaling, corrosion, and fluctuating operating conditions during the online operation of industrial flowmeters, the online calibration system adopts the standard meter comparison method to achieve uninterrupted metrological traceability. By combining error source classification and sound velocity verification for dynamic compensation, the flow error within the optimal wall thickness range is reduced to 0.38%. After the system modification, the electrode drift is controlled within ±0.22%, and the annual downtime is reduced from 144 hours to zero, validating the application value of this technology in terms of both accuracy and efficiency.

As a critical instrument in industrial process control and safety monitoring, the improvement of metrological verification and fault handling techniques for pressure gauges is of great significance for ensuring the accuracy of measurement data and the reliability of equipment operation. Focusing on the standard procedures of metrological verification of pressure gauges, including appearance inspection, zero-position inspection, indication error verification, and hysteresis error verification, this paper analyzes the technical key points and operational difficulties of each stage, such as the rational selection of reference standards, precise control of environmental conditions, and effective handling of nonlinear errors. In response to common faults encountered in actual use, such as pointer faults, dial plate faults, and internal mechanical component faults, the underlying causes are systematically explored, including mechanical wear, Bourdon tube leakage, material aging, and external environmental interference. On this basis, handling techniques and methods for different types of faults are proposed, covering core operational key points such as pointer calibration, dial plate repair, Bourdon tube replacement, and gear maintenance. By standardizing the metrological verification process and adopting scientific fault handling methods, the operational stability and measurement accuracy of pressure gauges can be effectively enhanced, their service life extended, and reliable technical support provided for industrial automation operation and safety protection.

In the standardization management of fiber testing, shortcomings such as fragmented systems, imperfect metrological traceability mechanisms, insufficient enforcement of standards, and a low level of informatization occasionally occur. This study constructs an integrated, whole-process standardization system, establishes a closed-loop management mechanism for error traceability, implements refined control measures at each stage, and strengthens the dual safeguards of professional personnel training and information technology. By doing so, it systematically reduces detection errors, effectively enhances the accuracy and traceability of testing data, and provides reliable support for the standardized and scientific development of quality control in fiber testing.

The quality control of special equipment (such as boilers, pressure vessels, elevators, and lifting machinery) must cover the entire process of design, manufacturing, installation, operation, maintenance, and scrapping. At present, the control system has weak links in information connection among various stages, daily inspection records, and the execution of inspection and maintenance cycles, which affect the safe operation of the equipment. Based on the requirements of full life cycle management, this paper analyzes the normative basis and optimization objectives, and proposes optimization paths including improving the mechanisms of design-manufacturing and installation handover acceptance and scrapping deregistration, implementing hierarchical control of the operating environment and dynamic verification of protection, strengthening the standardization of daily records and the construction of information platforms, strictly enforcing inspection and maintenance cycles and rectification and cancellation, and enhancing the competency of personnel. It is expected to provide a reference for improving the quality control level of special equipment throughout the entire life cycle.

In textile and cable production lines, traditional laboratory calibration of industrial roller-type length counters suffers from low efficiency and difficulty in replicating field conditions, and struggles to fully meet the requirements of JJG 987-2004 "Verification Regulation for Cable Length Meter", JJF (Textile) 066-2015 "Calibration Specification for Roller-Type Digital Display Fabric Length Measuring Instruments", and JJF (Lu) 206-2024 "Calibration Specification for Roller-Type Length Counters". To address these problems, a portable on-site calibration device based on virtual instrumentation was developed. The device employs a high-resolution photoelectric encoder and a precision measuring wheel to form a standard measurement module. It uses an NI data acquisition card to simultaneously collect the standard-length signal and the unit under test signal. LabVIEW software enables automatic calibration, synchronous processing, error calculation, uncertainty evaluation, and report generation. Field verification demonstrates that within the range of 0 m/min~120 m/min, the relative expanded uncertainty is better than 0.02% (k=2), the standard deviation of repeatability is less than 0.002 m, and the calibration efficiency is increased by more than five times.

Heavy metal pollution in textile wastewater runs through the entire production process, with the dyeing and finishing stages being the most prominent. The pollution forms include dissolved, complexed, and suspended states, among which the dissolved and complexed forms pose the main ecological risks due to their strong stability and high mobility. After entering water bodies, heavy metals induce oxidative stress, inhibit enzyme activity, and disrupt cellular structures, exerting multi-level toxic effects on microbial communities, planktonic algae, and aquatic animals, and ultimately threaten human health through transmission along the food chain. At the governance technology level, the fiber adsorption method has attracted attention for its advantages of simple operation and low secondary pollution. Natural fibers achieve adsorption through the complexation and electrostatic interactions of surface functional groups, while synthetic fibers mainly rely on physical entrapment; both are limited by adsorption capacity and selectivity. Modified functional fibers, through chemical grafting or nanocomposite incorporation of specific groups, can significantly enhance adsorption performance and achieve synergistic redox conversion. The adsorption process follows a pseudo-second-order kinetic model, conforms to both Langmuir and Freundlich isotherm laws, and is characterized as a spontaneous, endothermic, entropy-increasing reaction.

Metrological digitization serves as a core supporting element for the iterative upgrading of the quality management system in the new era and plays a significant role in enhancing quality control efficiency. This paper first examines the supporting logic of metrological digitization from the pre-process, in-process, and post-process dimensions of quality management, and summarizes three core characteristics: real-time capability, precision, and traceability, that emerge from the metrological digitization-driven system iteration. It then deconstructs the core elements of the adaptation between metrological digitization and the quality management system at the levels of the metrological data collection end, the analysis layer, and the application end. Finally, implementable pathways are proposed. The research conclusions can provide theoretical reference and practical guidance for optimizing quality management models and elevating quality control levels by leveraging digital technology.
