以涤纶纱线为原料，制备不同凹凸条组织与宽度的牙签条涤纶基布，并与平纹基布对比，系统评估其工业用性能与过滤性能。结果表明，牙签条涤纶基布因其立体多层的孔隙结构，展现出优异的综合性能。在凹凸条组织方面，缎纹和斜纹组织因交织点少、浮长线长，具有气流通道顺畅、过滤阻力低和抗冲击性好的特点，过滤性能优异。在凹凸条宽度方面，凸条宽度增加在提升过滤阻力的同时显著提高了拦截效率，使综合过滤性能改善；凹条宽度增加虽有利于提升拦截效率，但是存在最佳宽度阈值。

Polyester-based cloth with toothpick strips with varying convex-concave stripe structures and widths were fabricated from polyester yarns. And systematically compared with the plain weave basic cloth produced to evaluate their industrial properties and filtration performance. The result indicated that polyester-based cloth with toothpick strips structure, characterized by its three-dimensional and multi-layered pore architecture, imparted superior overall properties. In terms of convex-concave stripe structures, satin and twill weaves demonstrated optimal filtration performance due to their fewer interlacing points and longer floats, which facilitated smooth airflow channels and lower filtration resistance, and provided good impact resistance. In terms of convex-concave stripe width, increasing the convex stripe width enhanced filtration resistance but significantly improved filtration efficiency, leading to an overall improvement in comprehensive filtration performance. Conversely, while increasing the concave stripe width also contributed to improved filtration efficiency, there existed an optimal width threshold.
