摘　　要：采用了一种新型工艺的熔喷无纺布,通过新型熔喷无纺布和传统熔喷无纺布的厚度和孔径测试来对比分析比较两种熔喷无纺布的厚度均匀度和孔径大小。同时,由于熔喷无纺布固有的亲水性能差特点,试验又进一步比较了不同质量浓度亲水助剂的情况下,含有PET的新型无纺布和纯PP无纺布的吸水性能以及芯吸性能的比较。结果表明:新型熔喷无纺布的厚度均匀,孔径大,织物更为蓬松。在亲水吸水性能上,样品在低质量浓度助剂的长时间作用下也能达到高质量浓度助剂作用的效果。且新型熔喷无纺布能吸收储存的水量也要比纯PP无纺布要多。在芯吸性能方面,虽然两种无纺布芯吸测试结果最终液面的爬升高度都趋于一致,但结合吸水率和芯吸的现象来看,新型熔喷无纺布的吸水率明显高于纯PP无纺布,且含水更多,也更保水。This paper uses a new process of Melt-blown non-woven, By testing the thickness and the aperture of the new melt-blown non-woven and traditional melt-blown non-woven, to comparative analysis to compare the two melt-blown non-woven fabric thickness and aperture.Because of the poor melt-blown non-woven hydrophilic inherent performance characteristics, we further compared that in different concentration of the hydrophilic additives absorbency and wicking performance of the new PET non-woven and the non-woven fabric which just containing pure PP. The result shows that the New melt-blown non-woven fabric with more uniform thickness, bigger aperture, and the fabric is more fluffy.In terms of water absorption of hydrophilic, Samples under the effect of low concentration of additives for a long time also can achieve the result of high concentration of fertilizer effect. And the new melt-blown non-woven fabric can absorb water stored more than pure PP non-woven fabric.On the core absorption performance, through the core test results, the two kinds of non-woven final climb height of the liquid level are almost the same.But in combination with water absorption, The new melt-blown non-woven water absorption was significantly higher than the pure PP non-woven.Combining with core suction phenomenon,The new melt-blown non-woven aqueous more water,and retention water better.
