介绍了芳纶1313、芳砜纶、阻燃黏胶3种材料的基本性能,重点对比研究了芳纶阻燃黏胶和芳砜纶阻燃黏胶混纺针织物的阻燃性能,并探讨了织物组织与密度对混纺针织物阻燃性能的影响。结果表明:芳砜纶阻燃黏胶混纺针织物比芳纶阻燃黏胶混纺针织物的阻燃效果好;织物的紧密程度和克质量对织物的阻燃效果有显著的影响,即织物越紧密,克质量越大,燃烧越困难,阻燃性能越好。 相似文献

为了提高聚丙烯阻燃性能,对炭纳米管、黏土、C60、富勒烯、聚倍半硅氧烷改性聚合物的阻燃性能和力学性能进行了综述,系统地归纳了5种纳米改性剂的阻燃机理。指出:目前任何一种阻燃剂都有自身缺陷,未来所需要的PP用阻燃剂不仅要大幅提高其阻燃性能,同时还要提高力学性能、热性能及其他物理性能。今后应深入研究纳米阻燃剂的表面改性技术,解决分散性、界面黏结性等问题,以减少其劣化材料力学性能的影响,提高阻燃效率。 相似文献

In this research work, dyeability of polypropylene (PP) fabrics due to laser irradiation was studied. The laser intensities used during the experiments were 3, 3.8, 4.2, and 4.8?W?cm?2. The morphology of the modified surfaces was investigated using scanning electron microscopy. Also, Fourier transform infrared spectroscopy was used to examine the functional groups of the corresponding samples. For the dyeing process, aqueous solutions, containing 3.0?wt.% of the Astrazon Red Violet 3RN (CI Basic Violet 16) dye, were employed. For comparing the amount of fabrics dye exhaustion, reflective spectrophotometer was used. Also, light and wash fastnesses of dyed samples were measured. The results show a significant increase in the color depth upon dyeing after treating PP fabrics with CO2 laser. 相似文献

为扩大聚丙烯非织造布在水处理领域的应用,采用丙烯酸树脂为预聚物,聚乙二醇(400)二丙烯酸酯(PEG(400)DA)为亲水单体,1?羟基环己基苯甲酮(184)为光引发剂,乙酸乙酯为溶剂,通过紫外光(UV)引发自由基聚合法进行聚丙烯(PP)非织造布的亲水改性。分别研究了预聚物、亲水单体和光引发剂的质量分数对改性PP非织造布亲水性能的影响。结果表明,当丙烯酸树脂、PEG(400)DA 和184 的质量分数分别为7%、13%、1% 时,改性PP 非织造布亲水性达到最佳,且具有良好的亲水持久性。扫描电子显微镜(SEM)测试结果显示,亲水改性剂牢固地包覆在PP纤维表面。亲水改性的PP非织造布具有较好的抗污染性能和耐酸碱性能。 相似文献

为探究湿、热环境对丝织品文物保存状况的影响,在110、130 ℃条件下分别对桑蚕丝试样进行干热老化和湿热老化模拟实验。借助万能材料试验机、色度计、扫描电子显微镜和傅里叶红外光谱仪对老化前后试样的抗拉强度、颜色、微观形貌和结构进行了分析。同时,提出了丝织品的寿命预测方程。结果表明:试样强度随老化时间呈线性下降,颜色变黄;干热老化和湿热老化后,纤维表面出现不同程度的破坏,且湿热老化后,纤维束交织形成的孔洞周围较其他部位溶蚀显著;纤维二级结构中β-折叠构象含量显著降低,与强度变化趋势一致;低温、干燥条件适于丝织品文物的保存。 相似文献

The protection of a human body against the negative environmental factors, especially the cold, is one of the crucial functions of clothing. Clothing creates a thermal barrier between the human body and the surroundings. The protective efficiency of clothing goods depends mostly on thermal insulation properties of textile materials applied in clothing. The clothing design, fitting to a user’s body, and a number of layers also play an important role in the phenomenon of the heat exchange between the human organism and its surroundings. The thermal insulation properties of textile materials can be measured by means of different testing devices, such as the “skin model,” the Alambeta, the Permetest, and the Thermo Labo. A measurement of clothing goods from the point of view of their thermal insulation is performed using a thermal manikin. The article presents an investigation of thermal insulation properties of vests by means of thermal manikin. The investigated vests have been made of different textile materials: woven and knitted. The thermal insulation properties of fabrics applied in vests have been measured by means of the Alambeta. The article presents and discusses the relationships between the thermal insulation of vests according to the thermal manikin and the thermal resistance of fabrics applied in the vests. 相似文献
