国外进口粘胶价格波动较大且易出现缺货断货现象,为探究产量与质量均已达到一定水平且价格相对低廉的国内粘胶纤维对国外粘胶纤维的可替代性,选择与粘胶纤维性能相近的棉纤维、与粘胶纤维互补性较强的涤纶纤维分别与粘胶纤维进行混纺实... 国外进口粘胶价格波动较大且易出现缺货断货现象,为探究产量与质量均已达到一定水平且价格相对低廉的国内粘胶纤维对国外粘胶纤维的可替代性,选择与粘胶纤维性能相近的棉纤维、与粘胶纤维互补性较强的涤纶纤维分别与粘胶纤维进行混纺实验,采用相同纺纱工艺纺制粘胶/涤纶(70/30)和精梳棉/粘胶(60/40)2种常用的粘胶混纺纱,每组纱线设计2种不同的线密度,并对比国内外粘胶混纺纱的性能差异。实验结果表明:因粘胶品牌的不同,国内外粘胶混纺纱在某些性能上存在一定的差异,但总体而言性能差异不大,因此在企业生产时,可优选价格较低的国产粘胶纤维,以提高企业的经济效益。 展开更多

Objective: To observe effects of Dan Wei Powder (胆胃散 Powder for treating the gall bladder and stomach) Tea Bag (DWSTB) on the aggregation rate of blood platelet in vivo and in vitro. Methods: Increase of the platelet aggregation rate in the rat in vivo was induced by carrageenin, and increase of the rabbit platelet aggregation rate in vitro was induced by adenosine diphosphate (ADP) and collagen, respectively. The effects of DWSTB on the platelet aggregation rate were investigated in vivo and in vitro, respectively. Results: The maximum in vivo platelet aggregation rate in the rat was significantly decreased after administration of 2.0 and 4.0 g·kg-1 DWSTB (P<0.05.P<0.01). The maximum rabbit platelet aggregation rate induced by ADP and collagen in vitro were suppressed significantly by 2.0-16.0 mg·mL-1 and 2.0-8.0 mg·mL-1 DWSTB, respectively (P<0.05.P<0.01). And the effect of DWSTB on platelet aggregation was raised with increase ofits dose. Conclusion: Dan Wei Powder Tea Bag can restrain the aggregation of platelet in vivo and in vitro. 展开更多
