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.

4 kinds of hydrostatic pressure methods commonly used of resistance to water penetration testing were compared and analyzed in this paper. 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.
