蓖麻蚕丝/镀银聚酯纤维/抗紫外天丝纤维/低熔点聚酯纤维功能复合膜材料的成形及其应用研究

Study on the forming and application of functional composite membrane materials with castor silk/Ag-PET/Tencelsun/LPET

将蓖麻蚕丝纤维与低熔点聚酯纤维(LPET)、镀银聚酯纤维(Ag-PET)和抗紫外天丝纤维(Tencelsun)共混,利用微型开梳联合机对混合原料进行梳理成网,采用超声振荡成膜和红外烘燥黏结的方式开发功能复合产品,并测试其电磁屏蔽效能、紫外线防护系数、抑菌率、保暖率、膜透气率、膜断裂强力等指标,结合相关标准进行对比分析。结果表明:该材料结构稳定,兼具防电磁和紫外辐射、抗菌、保暖性能于一体。按照4因子3水平设计正交试验方案,利用灰色聚类分析进行程序化优化,确定最佳工艺。

Abstract： Castor silk,LPET,Tencelsun and Ag-PET were blended and combed into net by the micro combing machine. Functional composite products based on the materials were developed by ultrasonic and infrared,and the shielding effectiveness,ultraviolet protection factor,inhibitory rate,thermal rate,membrane permeability,breaking strength and other indicators were tested and compared with standard,results indicated that： the material structure is stable and it also have anti-electromagnetic and ultraviolet radiation,antibacterial,thermal insulation properties in one. Orthogonal experiment and gray clustering methods was used to achieve the optimized condition.
