为赋予丙纶非织布生物保健功能，对其进行氨气低温等离子预处理后，在异氰酸酯交联剂的作用下采用莽草酸对其进行接枝改性.采用傅里叶变换红外光谱分析改性前后非织布表面化学成分的变化，考察反应时间、温度、交联剂用量及莽草酸质量浓度对接枝率的影响，并对改性前后非织布的吸放湿效应、抗菌性及抗炎性进行测试.结果表明：氨气低温等离子体预处理后丙纶基体产生了可接枝反应的活性基团，异氰酸酯交联剂和莽草酸及预处理后的丙纶之间发生了架桥反应；最优接枝反应条件为交联剂IPDI 0.15 g、莽草酸质量浓度15 g/L、反应温度55℃、时间6 h，此时丙纶非织布接枝率为3.02%，其吸放湿性能优于未处理的丙纶非织布，且具有良好的抗菌性和抗炎性，对金黄葡萄球菌和大肠杆菌的抑菌率分别达到了97.6%和94.4%.
為賦予丙綸非織佈生物保健功能，對其進行氨氣低溫等離子預處理後，在異氰痠酯交聯劑的作用下採用莽草痠對其進行接枝改性.採用傅裏葉變換紅外光譜分析改性前後非織佈錶麵化學成分的變化，攷察反應時間、溫度、交聯劑用量及莽草痠質量濃度對接枝率的影響，併對改性前後非織佈的吸放濕效應、抗菌性及抗炎性進行測試.結果錶明：氨氣低溫等離子體預處理後丙綸基體產生瞭可接枝反應的活性基糰，異氰痠酯交聯劑和莽草痠及預處理後的丙綸之間髮生瞭架橋反應；最優接枝反應條件為交聯劑IPDI 0.15 g、莽草痠質量濃度15 g/L、反應溫度55℃、時間6 h，此時丙綸非織佈接枝率為3.02%，其吸放濕性能優于未處理的丙綸非織佈，且具有良好的抗菌性和抗炎性，對金黃葡萄毬菌和大腸桿菌的抑菌率分彆達到瞭97.6%和94.4%.

In order to endow the polypropylene (PP) non-woven with biological healthcare function, polypropylene (PP) non-woven was exposed to low-temperature ammonia plasma treatment, then shikimate is grafted onto the surface of polypropylene non-woven by isocyanate cross-linking agent. Surface chemical compositions of PP non-woven are analyzed by Fourier transform infrared spectroscopy. The effects of reaction time, temperature, the amount of the crosslinking agent and the concentration of the shikimate on grafting rate were investigated. The absorption and release humidity effect, anti-bacterial and anti-inflammatory of non-woven fabric were tested before and after the modification. The results showed that after the ammonia plasma treatment, some reactive groups are generated on the surface of PP. The isocyanate reacts with the pretreated PP and shikimate. Optimal conditions of grafting reaction is that crosslinking agent of IPDI is 0.15 g, shikimic acid concentration 15 g/L, reacted at 55℃for 6 h, the graft rate of polypropylene non-woven is 3.02%. Its absorption and release humidity effect is better than those of untreated polypropylene non-woven, and it has a good anti-bacterial and anti-inflammatory properties, the inhibition rate of S. aureus and E. coli reaches 97.6%!and 94.4%, respectively.
