羽毛纤维/聚丙烯熔喷滤芯的制备及其过滤吸附性能

提供一种利用废弃羽毛的方案,以解决现有废弃羽毛对环境污染的问题.先用Na2S2O5对羽毛纤维进行改性处理,以提高其重金属吸附能力,并用傅里叶红外光谱(FTIR)分析了改性前后羽毛纤维的结构变化.然后将羽毛纤维制成熔喷滤芯,并测试其对Pb2+的过滤吸附性能.结果发现,Na2S2O5可有效提高羽毛纤维对Pb2+的吸附能力,且改性羽毛纤维/聚丙烯熔喷滤芯相比于羽毛/聚丙烯熔喷滤芯和纯聚丙烯熔喷滤芯,在整个动态吸附过程中表现出了更好的过滤和吸附效果,并可通过调整熔喷工艺制备不同体积密度的羽毛纤维/聚丙烯熔喷滤芯.     

亲水整理对医用聚丙烯SMS脂肪纯化材料性能的影响

采用亲水剂喷淋-烘焙的方法和正交试验对聚丙烯纺黏-熔喷-纺黏(SMS)非织造脂肪纯化材料表面进行亲水整理,通过扫描电子显微镜、傅里叶变换红外光谱仪、接触角测量仪、倒置显微镜等仪器,对亲水整理前后聚丙烯SMS非织造材料的微观形态、化学结构、亲水性能、细胞毒性、纯化效果等进行表征。结果表明:亲水整理工艺中亲水剂质量分数、烘干温度、烘干时间分别为7%、100℃、140s时,整理后的聚丙烯SMS非织造材料的液体穿透时间最短;亲水整理后聚丙烯SMS非织造材料孔径分布更加集中且无细胞毒性;与医用棉纱布过滤法、离心法等相比,采用经亲水整理的聚丙烯SMS非织造材料进行过滤对脂肪的纯化效果最好。     

SMS手术衣材料的“三拒一抗/单向导湿”双面泡沫整理

Packaging Bags with the Function of Micro-environment Modification

Three kinds of packaging bags composited with barrier film and moisture absorbents were designed in order to find out how to create an internal micro-environment with low 02 content and relative humidity （RH）. Peanuts with different moisture contents were filled into packaging bags and stored in an environmental chamber for a certain period of time. An RH recorder was sealed in each bag and the RH inside the bag was recorded. The moisture contents of peanuts before and after storage were measured as well. It is found that peanuts with moisture content of 13 % can reduce 02 content inside the bag by the aerobic respiration, achieving the self modified atmosphere packaging （ MAP ） effect. A micro- environment with lower RH can be created by using super-absorbent fiber （SAF） or mineral bag as the moisture absorbent. The moisture contents of peanuts stored in the bags with SAF and mineral bag as moisture absorbent decreased from 13% to 10.5% and 11.3%, respectively. SAF is a promising material of packaging bags composited with barrier film, in which a low RH and high CO2 content can be created.     

壳聚糖/黏胶水刺医用敷料的制备及其性能

在不同水刺压力下分别采用平行铺网和交叉铺网方式,制备了壳聚糖与黏胶混纺比为80/20和60/40的水刺医用敷料,并对试样的刚柔性、液体吸收性、透气性、水浸出液pH值和水中溶出物性能进行了对比和分析.结果表明:壳聚糖/黏胶水刺医用敷料的柔软性、液体吸收性、透气性、pH值和在水中溶出物的质量分数随着壳聚糖纤维含量的增加呈上升趋势;水刺压力增大时,水中溶出物减少,pH值未见显著变化,而柔软性、液体吸收性和透气性变差.

佛道文化与唐代武侠小说

唐代武侠是最早的具有现代意义的武侠，唐代武侠小说的模式预示了后代武侠小说的发展方向，标志着以写实为特点的侠客传记向以虚构幻想为特点的武侠小说的转变；唐代佛道文化的繁荣鼎盛，是这种转变的原因。     

Packaging Bags of Peanuts with Function of Prevention of Aflatoxin B₁

Packaging bags composited with barrier film and moisture absorbent nonwoven fabrics were prepared in order to design a kind of functional bag which could prevent the contamination of aflatoxin B1of peanuts. The internal relative humidity( RH) of packaging bags with peanuts was monitored. The influences of the superabsorbent fiber( SAF) and jute fiber were investigated and the mechanism was analyzed.
