The defect “Chika” in Rayon fabrics is studied, first by selecting “Chika” structure itself and the structual relation of warp and weft yarns was noted. The weft yarns have but little effects on formation of “Chika”, and warp yarns only can cause the defect. It is found that “Chika” formation process takes place at the clothfell on the loom, the point that has not been established hitherto.
The methods of preventing the “Chika” are deviced from the results of our experiments. Our “Chika” seems to be the same phenomenon as “Teary” descrived in “The Fabric Defects” McGraw Hill Co., but differ from “Tear Drop” in A. S. T. M. Appendix II.
