Optical Properties of Woven Fabrics by Plastic Optical Fiber

Abstract

Plastic Optical Fiber (abbreviate POF) is used in the various fields; short range communication, sensor, illuminate exploitation and so on. The fabric is one of the forms in illumination fields, but there are no reports about the lighting properties of POF fabrics. In addition, for the fabric development, it is very important to estimate the optical characteristic in the textile design stage.In this report, the lighting properties of POF fabrics are measured and the new method to estimate the optical properties of POF fabric is suggested.

Mechanical Properties and Sensibility Evaluation of Jacquard Fabric with Optical Fiber

“…그 러나 광섬유에 관해서는 직물 및 의류 적용에 관한 연구가 진 행되고 있을 뿐, 감성적인 평가에 관한 연구는 미비한 수준이 다 (Kang et al, 2011;Kim et al, 2012;Masuda et al, 2006;Park et al, 2009). Table 2와 같다.…”

“…There, the theoretical side-luminance can be related to both bending radius and weaving style. [ 150 ] = + ≈ h 4 16h 16h 2 2 r p p (11) In weaving, the assigned weft and warp threads are interlaced with each other in a produced fabric, as, e.g., in an 4/1-twill weave ( Figure 14 (left)). The varying fi nal fabric thickness h and the period of the optical fi ber crossing p result in drastically different radii of curvature of the optical fi bers: For a satin weave 4 and 8 (the weft yarn is alternatingly 4, respectively, 8 times above and then once below the warp yarn) at the same thickness, the radius quadruples (from Equation ( 11).…”

“…Other groups have worked on assuring homogeneity of lateral light out-coupling with the fabric's medical potential in mind. [ 150 ] Hence, to increase resilience and prevent losses, weaving of cotton fi bers around a polymer optical fi ber has been tested. The luminance has to be kept constant over the entire area of the fabric to ensure uniform treatment.…”

“…The light intensity detected from the textile over the light intensity from the source gives the effi ciency ratio. [ 150 ] Hence, to increase resilience and prevent losses, weaving of cotton fi bers around a polymer optical fi ber has been tested. It showed better mechanical properties and allowed for postmanufacturing into a textile with both power and hand loom.…”
