    Perfluorinated and polyfluoroalkyl compounds (PFAS) are widely used in the textile industry because of their excellent thermal stability and degradation resistance, such as waterproof treatment, fireproof coating and so on. However, the persistence, long-distance migration, bioaccumulation and biotoxicity of PFAS have caused long-term adverse effects on human health and environment, and have been referred to as "permanent chemicals". In recent years, the control of PFAS by many countries and in- ternational organizations around the world has become increasingly strict, and the textile industry needs to actively respond to this trend. This article reviews the updates of PFAS regulations in the European Union, the United States, China, as well as the latest re- quirements of Bluesign, AFIRM, ZDHC and other institutions, and discusses the compliance testing and response suggestions of the textile industry.

    In order to study the dyeing properties of three natural plant dyes of artemisia argyi, purslane and huaimi on cotton fabric, three plant dyes were extracted by Soxhlet extraction method, and the cationic modified cotton fabric was dyed with dye solution. Then, the dyeing properties of the three dyes under different dye dosage, dyeing temperature, dyeing time and pH value were explored and the optimal dyeing process conditions were determined. Finally, the color fastness properties of the three dyes under the optimal dyeing process conditions were tested. The results showed that the optimal dye dosage of artemisia argyi and purslane was 150 mL/L, and that of huaimi was 100 mL/L. The optimum dyeing temperature of artemisia argyi leaf was 50 ℃, while that of purslane and huaimi were 80 ℃ and 70 ℃ respectively. The optimal dyeing time of artemisia argyi and huaimi was 60 min, and that of purslane was 75 min. The optimal dyeing pH value of the three dyes was 7. The modified cotton fabric dyed with artemisia argyi, purslane and huaimi has good color fastness.

Through observation and analysis the test end point phenomenon of common waterproof fabric, test comparison between the method with metal mesh and without metal mesh, and test comparison between the low hydraulic pressure method and the high hydraulic pressure method, to analyze the resistance to water penetration performance of different waterproof fabrics. The results show that, the multi-layer composite fabric and coated fabric often obtain higher hydrostatic pressure value in the test, and the typical third spot of water droplets cannot be observed, which will affect the determination of the end point of the experimenter and lead to the difference of the test results. the metal mesh installed in the test can disperse the force on the fabric surface, which can effectively prevent the sample from excessive deformation during the pressure process, but often obtain a higher hydrostatic pressure value. In the test process of high hydraulic pressure method, the water has not penetrated the fabric surface before reaching the pressure limit of the sample itself, causing the sample to burst and testing termination. This method is more suitable for the sample whose pressure value is much higher than the hydrostatic pressure value.

    Aiming at the problems of poor objectivity, low efficiency and low accuracy in the identification methods of down feath- er species, an identification method used by near infrared spectroscopy was proposed in this study. The structural composition, chemical and optical properties of goose feather, goose plush, duck feather and duck plush were quantitative evaluated by the near infrared spectrum. Moreover, the feasibility of the method was confirmed by principal component analysis. The results indicated that the comprehensive recognition degree of transmission infrared spectrum is 50%~60%, and the comprehensive recognition degree of diffuse infrared spectrum is 70%~80%. The near infrared spectroscopy method can qualitatively identify the category of down feathers. This identification method is conducive to improve the product quality assurance of plush, safeguard the rights and interests of consumers, promote the standardized development of the market, and provide reference for practitioners and testing per- sonnel in related industries.

    Cotton official classification is an important technical support to promote the reform of cotton target price policy, but also an important guarantee to implement the effective supervision of cotton and promote the improvement of cotton quality. In 2023, the key indicators of cotton in Hami region increased significantly, with an average length of 29.29 mm, 0.39 mm higher than the average length of cotton in 2022, the average fracture ratio intensity of 29.86 cN/tex, 1.31 cN/tex more than 2022, 93.42% of cot- ton has reached up-to Micronaire value A + B grade, 7.07 percentage points more than that in 2022, reaching the national standard of high-quality cotton. There are some problems regarding cotton color grade and cotton consistency. The cause for the problems includes seed quality, cotton field management, and cotton harvesting, purchasing and processing. This paper has proposed the es- tablishment of a cooperation platform between industry-university-research to promote the development of modern agriculture, to construct the high-standard farmland, and to promote the high-quality development of cotton industry, characterizing modernization, intelligence and information of cotton production. Finally, there are four suggestions to strengthen quality supervision and technical assistance.
