The results showed that the m-PUE had better heat-resistant properties, lower glass transition temperature, higher thermal decomposition temperature and better damping property. The internal friction peak was changed from 10 ℃ to -10 ℃, while the tan δ was changed from 0.28 to 0.46. The hardness, tensile strength and tear strength of m-PUE decreased with the increase of the THEIC content. However, the swelling ratio of PUE was increased meaning a deteriorated solvent resistance property.

结果表明，引入IS环后，PUE的耐热性能有提高；IS改性的PUE的内耗峰比未改性的窄，峰位由10℃移到-10℃，且内耗峰值增大（tanδ由0.28增大到0.46），玻璃化温度降低，而阻尼性能得到提高；引入IS环的PUE的硬度和其它力学性能比未改性的PUE有所降低；随着固化剂中THEIC用量的增加，PUE的溶胀率增大，即IS改性PUE的耐溶剂性变差。

The fifth plan was desirable one for the development of medical barrier fabrics with fine comprehensive properties. In this plan, one-layered texture with differential face, which made fibers disposed in three layers, was selected as texture of upper and inferior layers, therefore the difficulties of weaving were reduced. Moreover, because superfine fibers with better performance and higher price were disposed only in liquid-repellent layer and ordinary polyester filaments with smaller fineness and lower price were disposed in inferior layers, the thickness and cost were reduced based on fine liquidrepellency.

通过对比分析得出，第五方案是在开发具有优良综合性能的医用屏蔽织物时最可取的一种设计方案，它的上、下层均采用了单层的异面组织，在高密下使纤维在织物呈三层配置，大大地降低了织造的难度，并且此方案仅在拒液层的经、纬向配置了性能较好、价格较贵的超细涤纶长丝，而在织物的下层配置了纱支较细、价格较低的普通涤纶长丝，这样就在保证织物具有优良的拒液性能的基础上降低了织物的厚度和成本。

Results showed that, the specific refining energy consumption is decreased with increment of rotation speed of the primary refiner. At freeness level of about 670 mL CSF, for example, the specific refining energy consumptions is 363 kWh/t o.d. at 3000 r/min, and 305 kWh/t o.d. at 3500 r/min, which is equivalent to 16% energy saving, furthermore the specific energy consumption is only 265 kWh/t o.d. at 4000 r/min, which means 27% less refining energy required. At the same time, pulps produced at higher refiner speed have higher strength properties and lower shives contents. There is little change of optical properties of the pulps.

结果表明：小叶桉物料在相同条件下进行汽蒸、挤压和化学预浸渍后，分别采用3500 r/min和4000 r/min的盘磨转速进行第一段磨浆，浆料磨至游离度670 mL时所需磨浆电耗与3000 r/min时的相比，分别下降16%和27%；浆料中纤维束含量分别降低20%和35%；第一段磨后浆料再分别经相同盘磨转速（3000 r/min）的后续磨浆后，与相近游离度的浆料性能比较可知，随第一段磨浆盘磨转速的提高，浆料的细小组分含量略有增加，纤维束含量显著降低，强度性能有不同程度的改善，但光学性能变化不显著。
