聚合物光纤发光织物的制备及其亮度测试

Preparation and luminance test of polymer optical fiber light-emitting fabrics

将PMMA/氟树脂聚合物光纤与棉纱相交织,形成8种不同组织的聚合物光纤织物,采用一定手段对织物中的聚合物光纤进行集束处理,并与光源进行耦合连接,形成聚合物光纤发光织物.使用LumiCam 1300 color图像亮度色度计对发光织物的亮度进行测试,探讨聚合物光纤在织物中的发光规律及在不同织物组织中纬纱覆盖率及弯曲半径对聚合物光纤亮度的影响.结果表明:聚合物光纤在织物中的亮度与距光源距离的关系呈二阶指数衰减,其衰减曲线符合双光源光纤侧发光规律,但波动较大;织物组织、经纬密及经纬纱线直径等织物组织结构参数均对聚合物光纤发光织物的亮度有着重要影响,在8种不同组织的织物中,由于1/4↗织物的纬纱覆盖率和弯曲半径明显高于其它组织,其亮度也最高.

The PMMA/fluororesin polymer optical fibers and the cotton yarns are cross woven to get eight kinds of fabrics with different weave structures. There are some measures used to cluster the polymer optical fibers, then they are connected with light-emitting diode to get the polymer optical fiber light-emitting fabrics. The light-emitting fabrics are tested by LumiCam 1300 imaging photometer, then the light-emitting regulation of the polymer optical fiber in the fabrics and the influence of weft coverage rate and bend radius on the luminance of fabrics are discussed. The results show that the luminance of the polymer optical fibers in the fabric presents second order exponential decay with the increase of distance. The curve accords with luminous law of double light source but with high fluctuation. The fabric weave, warp and weft density and the diameter of yams have a great influence on the luminous of the fabrics. In the eight kinds of fabrics, the luminous of 1/4 fabric is the highest because of the highest rate of weft coverage and bend radius.
