Comparative Study of Polypropylene Non-Woven Surgical Mask and Locally Manufactured Woven and Knitted Fabrics Facial Masks

The outbreak of coronavirus has led to an increase in the demand for facemasks globally. Unavailability of appropriate polypropylene non-woven fabrics face masks as a result of inadequate supply to satisfy the growing population has brought about the manufacturing of locally fabrics masks to augment or substitute standard medical class facemasks. The study aims at analyzing airflow of these locally manufactured fabrics to determine possible means of transmitting the virus as well as establish comfort of the user of these masks. Standard polypropylene non-woven, woven and knitted fabrics were considered for the study. Air permeability test was conducted on these fabrics using Frazier Air permeability tester. Depending on the property significant variation in the textile fabrics, polypropylene non-woven is widely accepted for facial masks. Nevertheless, this study illustrates that woven and knitted fabrics have more open structures, which allow a high rate of air penetration and so may require two or three layers to prevent antimicrobial or antiviral potential.

面膜用非织造布的结构与性能

分别以水刺法蚕丝面膜基布和手工法蚕丝面膜基布为研究对象,测试面膜基布的力学性能、透气性能和持液率,探讨面膜结构、性能与应用的关系。试验结果表明:水刺法面膜基布的拉伸性能较好;手工法面膜基布具有优良的透气性能,并且持液率较高。

超吸水聚酯纤维面膜基布的制备与性能研究

采用新型超吸水聚酯纤维和黏胶纤维分别与普通聚酯纤维混纺,再经水刺加固工艺,制备不同混纺比及不同面密度的水刺面膜基布,测试并分析它们的力学性能、柔软性能、透气性能、透湿性能、吸液性能及保液性能,结果表明:新型超吸水聚酯纤维与普通聚酯纤维混纺制得的水刺面膜基布的厚度较薄,拉伸断裂强力大,柔软性好,透气性和透湿性明显优于黏胶/普通聚酯纤维混纺水刺面膜基布,吸液性能较黏胶/普通聚酯纤维混纺水刺面膜基布有所减小,保液性能优异。
