Biodegradable refers to the decomposition that occurs under the action of biological activity, gradually decomposed by microorganisms or certain organisms as a source of nutrition, and ultimately decomposed into structurally simple compounds, inorganic salts, and biological dead bodies. Biodegradable textile materials mainly include natural fibers such as Hemp, Cotton, Bamboo, regenerated fibers such as Viscose, Modal, and Lyocell, as well as new synthetic fibers such as PLA and PHA. The optimal degradation performance of biodegradable textile materials is related to their structural composition and is mainly limited by degradation conditions. In this paper, the biodegradation rates of microcrystalline cellulose, hemp, cotton fiber and cotton non-woven fabric were measured under aerobic composting degradation conditions. Combined with the test results of other researchers, the effects of the chemical composition of textile materials, the selection of biodegradation test methods, and the organizational structure of textile products on the biodegradation test results of textile materials and products were analyzed. Then, the CO₂ content in the mixed gas was determined by “absorption method” and “non-dispersive infrared spectroscopy method”, which was the typical data measurement methods of aerobic biodegradation test methods, and it was proposed that the data measurement methods of aerobic degradation test methods have uncertain effects on the biodegradation test results. This study is conducive to standardizing the biodegradation test and evaluation of biodegradable textile materials, and promoting the green development of new technologies and materials in the textile industry.

With the increasing number of pet-keeping families, the scratching damage caused by pets to home textiles has attracted growing attention, making the development of pet scratch-resistant textiles increasingly urgent. However, there is currently no objective and effective test method to evaluate the scratch resistance of textiles. In this paper, a test method for evaluating the pet scratch resistance of textiles is proposed. Firstly, textile samples are pre-treated with scratching using a self-developed pet scratching device, and then the damage degree of the textiles is graded. Common fabrics available in the market were selected, and their pet scratch resistance was evaluated using the proposed method. The test results show a high consistency with the actual situation in daily life, indicating that the proposed test method can objectively and reliably test and evaluate the pet scratch resistance of textiles. It is easy to operate and has good repeatability, thus providing a reference for the research and development as well as quality control of pet-related functional textiles.

Radioactive cooling textiles significantly enhance thermal comfort for individuals in high-temperature environments or during outdoor summer activities, this emerging field has garnered substantial research interest and demonstrates promising market potential. Research on radiative cooling textiles has primarily focused on the advancement of radiative cooling technologies and the development of novel materials, while relatively limited attention has been paid to the instrumentation and methodologies for performance evaluation. Conducting research on the development of testing apparatus and methodologies for radiative cooling is crucial for accurately assessing the performance of textiles in this domain, thereby significantly promoting industrial advancement. This study successfully developed a testing instrument for evaluating radiative cooling performance, investigated the influence of factors such as irradiance and exposure duration on test outcomes, and measured the temperature differential within the test chamber before and after the application of the textile samples., thereby establishing a standardized testing method for assessing textile radiative cooling performance under simulated sunlight conditions. This research can provide a reference for formulating the standard test method for the radiation cooling performance of textiles.

This study investigated the thermal blocking property of 50 representative commercially available umbrellas using a self-developed testing system. The results revealed significant variations in thermal blocking performance among different umbrellas, with thermal blocking rates ranging from 2.3% to 83.0%, demonstrating a clear performance gradient. Among them, plastic umbrellas exhibit very low thermal shielding capability (2.3%~29.9%); ordinary fabric umbrellas show moderate performance (37.1%~58.8%); Coated umbrellas and double-layer/wind-resistant fabric umbrellas demonstrated superior thermal shielding performance, with shading rates of 61.4%~83.0% and 57.8%~75.4% respectively. This study represents the first application of a three-dimensional testing system ("metal manikin-complete umbrella specimen-solar simulator") for evaluating the thermal blocking performance of full-scale umbrellas, the whole-umbrella testing method effectively quantified and differentiated the thermal blocking properties of various umbrellas, systematically revealing the performance distribution characteristics of commercial umbrellas. The study confirms that while the canopy material forms the foundation of thermal shielding performance, factors such as the three-dimensional structure of the entire umbrella and the design of the ribs collectively contribute to performance variations among products made of the same material. The findings provide solid data support and theoretical foundation for product improvement and informed consumer decision-making.

This paper proposes a testing method for rapidly and accurately determining the density of different types of woven fabrics by using a high-definition image acquisition instrument and an X-Y axis translation and rotation observation platform to build a high-definition image acquisition system. Forty batches of plain, twill, coated, and composite woven fabrics of different shades were randomly selected and the densities of the warp and weft directions were tested by the high-definition image acquisition system and the manual fabric decomposition method respectively. The experimental results show that this method is widely applicable to the density testing of plain, coated, twill (lightweight type), and composite woven fabrics, with a relative deviation of the test results within 3% and a time-saving of more than 70%. It has the advantages of accuracy, efficiency, and traceability. For special types of woven fabrics such as coated and composite fabrics, the pretreatment process can be omitted. By magnifying and observing the fabric structure of special types of woven fabrics such as “water-soluble yarn” and “checkered fabric”, the problem of missing yarns during density testing can be prevented.
