3. Material friction coefficient determination: Friction coefficient between the sock sole material and different surfaces (e.g., yoga mats, wooden floors, tiles), friction contribution rate of material surface texture, analysis of micro-friction behavior of contact surfaces, etc.
4. Abrasion resistance and anti-slip durability testing: Changes in anti-slip coefficient after simulated wear and tear, abrasion resistance revolutions, surface texture wear depth, anti-slip particle shedding rate, anti-slip performance retention rate after washing, long-term performance degradation evaluation, etc.
5. Sock Stretching and Deformation Effect Test: Changes in anti-slip coefficient under different stretching rates, differences in anti-slip performance between tight and loose socks, anti-slip stability after deformation caused by foot movement, and the ability of elastic recovery to maintain anti-slip properties.
6. Moisture Wicking Effect Test: Anti-slip performance under sweat-soaked conditions, changes in material surface properties after moisture absorption, the impact of wicking channels on the contact surface, and anti-slip retention in humid environments.
7. Low and High Temperature Environmental Adaptability Test: Anti-slip coefficient under different ambient temperatures, the effect of thermal expansion and contraction of materials on the anti-slip structure, anti-slip performance after storage at extreme temperatures, and temperature cycling tests.
8. Anti-slip Structure Effectiveness Evaluation: The rationality of the design of anti-slip points/patterns, the relationship between the distribution density of anti-slip units and anti-slip force, the contribution of structural height and aspect ratio to grip, and verification of the effectiveness of biomimetic structures.
9. Comfort and Anti-slip Correlation Test: Pressure distribution of the anti-slip structure on the sole of the foot, assessment of the balance between anti-slip force and restraint, and changes in anti-slip behavior due to changes in comfort after prolonged wear.
10. Multi-directional Anti-slip Performance Test: Anti-slip force in the front-to-back direction, lateral anti-slip force, anti-slip performance under rotational torque, and the critical point of anti-slip failure under combined directional forces.
11. Safety Performance Test: Assessment of the risk of slippage due to anti-slip failure, anti-slip reliability in emergency situations (such as rapid movement), and whether the anti-slip structure poses a risk of snagging.
12. Anti-slip Performance Test of Environmentally Friendly Materials: Comparison of the anti-slip performance of yoga socks made from biodegradable or recycled materials with traditional materials, and the impact of environmentally friendly processing on anti-slip properties.
