제안 방법
- In this work, the breathable waterproof fabrics manufactured through laminating process were used, and some constructive properties and mechanical properties with small and large deformation were measured and analyzed according to laminating process, fabric construction and so on. Then, the alteration of the fabric performance after laminating process and deformation behavior with increase of strain in this composite system was investigated in comparison with pre-laminated febrics.
- The uniaxial tensile testing was made according to ASTM D 5035. The specimens were prepared with raveled strip method and cut strip method before and after laminating fabrics, respectively. Yield point was calculated according to Meredith's constructione.
데이터처리
- Sixteen mechanical characteristic values were evaluated and the respective results were used for analyzing paired t-test. Table 4 shows the mean and t-values of the mechanical properties.
이론/모형
- 5gf/cm2 load. Adhesive force between the base fabric and polymer membrane was measured in accordance with ASTM D 4851 using constant-rate- of elongation tester.
- Tensile properties, shear properties, bending properties, compression properties, and surface properties with small deformation were measured with KES-FB system13), which is an objective evaluation system based on standardized subjective expression of fabric hand. FYom this system, 16 characteristic parameters were measured, and the primary hand values were calculated with KN-101-Winter equation.
- The tearing strength was measured with tongue method according to ASTM D 2261 before and after laminating. The uniaxial tensile testing was made according to ASTM D 5035. The specimens were prepared with raveled strip method and cut strip method before and after laminating fabrics, respectively.
