By performing DSC melting point tests on blends of polyamidoester and polyester fibers at different ratios during first and second heating cycles, and comparing with the melting point method using a microscope, it was demonstrated that in the sec- ond heating cycle test of DSC, the melting point of polyamidoester or polyester fibers cannot be directly obtained when the content is low in the blended sample. There are cases of missed inspections. Additionally, the melting point method using a microscope is more clear and intuitive for distinguishing the melting points of polyamidoester and polyester fibers in blended samples compared to the DSC melting point method, especially for samples with low polyamidoester content. Therefore, the melting point method us- ing a microscope is more suitable for identifying blends of polyamidoester and polyester fibers than the DSC melting point method, providing a practical theoretical basis for the identification of blended products containing polyamidoester and polyester fibers.

(3) In the heterogeneity analysis, digital transformation has a prominent effect on the promotion of green growth of textile firms in state- owned, non-state-owned, and eastern areas, but not in the central and western areas.

Bamboo shoot shell cellulose was extracted from bamboo shoot shells using caustic soda treatment. Superabsorbent polymer(SAP) was prepared from bamboo shoot shell carboxymethyl cellulose(CMC) as the grafting skeleton, acrylic acid(AA) and acrylamide(AM) as monomers. The successful preparation of SAP was confirmed by infrared spectroscopy analysis. Single-factor experiments and orthogonal experiments were used to optimize the preparation conditions as follows: CMC dosage of 16%, m (AA):m (AM)=4:1, neutralization degree of acrylic acid at 60%, initiator dosage of 3.5%, crosslinking agent dosage of 1.5%, and the reaction was carried out at 60 ℃ for 1.5 hours. The SAP had absorption capacity of 518 g/g and salt tolerance capacity of 55 g/g. At room temperature, its water retention rate was as high as 99%, and it can be reused for multiple water absorp- tions, reaching 55.6% of the saturated absorption capacity within 1 hour.

Impurity rate test is one of the important indicators of cotton notarization test, which provides a basis for cotton transaction price and fairness. CGT-1 intelligent tester of raw cotton impurity realizes the full automation of raw cotton impurity rate test, which plays an important role in the inspection of Xinjiang regulatory cotton. Due to the particularity of Xinjiang regulatory cotton inspection, it takes a long time, high strength, overload and uninterrupted operation during the peak period of cotton inspection, which is easy to increase the frequency of failure. Once the equipment fails, it will inevitably affect the normal inspection work. This paper summarizes the common faults in the operation of CGT-1 tester, and puts forward the corresponding solutions, which ensures the accuracy and stability of the test data and improves the test efficiency.

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.

Atlas silk, with its distinctive ethnic features in Xinjiang, has garnered widespread attention in recent years, fueled by the growth of Xinjiang’s tourism industry and gradually integrating into people’s daily lives. However, the development of Atlas silk craftsmanship has been sluggish, with severe issues of color fading and color transfer, hindering the expansion of its market and brand promotion. This paper focuses on this issue, analyzing the factors affecting the colorfastness of Atlas silk, which chiefly include outdated dyeing techniques, a miscellaneous use of dyes and auxiliaries, inadequate quality control of raw materials, insufficient standardization of production processes, and a lack of awareness regarding product quality control among enterprises. Accordingly, the following recommendations are proposed: preserving traditional handcraftsmanship for high-end products while enhancing dyeing techniques for mid- to low-end products and encouraging the adoption of new technologies; reinforcing the consciousness of quality control, optimizing enterprise management, and encouraging third-party institutions to fulfill their roles by providing technical assistance; facilitating standardized production for product quality enhancement and reinforcing the protection of local specialty products.

In order to ensure the accuracy and efficiency of fiber content analysis on silk/wool blended products, com- parative experiments were conducted to analyze the feasibility of using the 56% sulfuric acid method for the quantitative analysis of such blended textiles. The experimental results indicate that the mass correction factor d for wool in a 56% sulfuric acid solution is 1.00. The extreme differences in the content measured by the 56% sulfuric acid method compared to the 75% sulfuric acid method, 35% hydrochloric acid method, and formic acid/zinc chloride method are all less than 3%, which complies with the fiber content tolerance described in GB/T 29862—2013. The experiment demonstrates that the use of the 56% sulfuric acid method for the quantitative analysis of silk/wool blended products is feasible.
