Table 1

Characterization of different PET-ALs (n = 6, mean ± SD).

Implant	Pore diameter; (m)	Porosity; (%)	Ultimate failure load; (kN)	Stiffness; (N/mm)
5A	153.4 ± 10.2	55.2 ± 0.9	6.6443 ± 0.1015	215.3 ± 15.6
3A	190.7 ± 12.1	72.4 ± 3.2	4.886 ± 0.0688	86.4 ± 3.2
5B	180.4 ± 15.9	68.3 ± 1.5	4.4210 ± 0.0980	92.6 ± 7.4
3B	245.3 ± 17.3	79.5 ± 2.2	2.5668 ± 0.0794	32.7 ± 2.7

“5” indicates that the PET-ALs were weaved with 5000 D PET fiber bundles. “5000 D” indicates 5000 grams weight of the 9000 meters PET fiber bundles under convention moisture regain.
“3” indicates that the PET-ALs were weaved with 3000 D PET fiber bundles.
“A” indicates that the PET-ALs were weaved in full-set threading warp knitting method.
“B” indicates that the PET-ALs were weaved in part-set threading warp knitting method.
