  Abstract: In order to solve the problem of many broken ends with viscose compact spun fine yarn to weave thin fabric before weaving，the performance difference between compact spun R 9.8 tex yarn and ordinary ring  yarn of the same size is compared，the problems and reasons for warping and sizing process are analyzed.Taking the weaving R 9.8×R 9.8 354.0×330.5 165.0 product as an example，the parameter setting and precautions of the warping process，as well as the selection of slurry，sizing process setting and sizing points of the sizing process are described in detail.It is pointed out that viscose compact spun yarn has low strength，easy elongation，and high sizing difficulty.Therefore，the warping process should ensure uniform tension，and the sizing process should choose lowviscosity slurry，without or with a little PVA.With a suitable sizing rate，high moisture regain and proper increase of unwinding tension，the leasing resistance and hairiness increment can be reduced，the yarn brittle break can be prevented and the broken ends can be greatly reduced.After optimizing the process，the loom efficiency of R 9.8×R 9.8 354.0×330.5 165.0 is greater than 94%，the broken ends of per machine and per hour is reduced to 0.9，and the quality of grey cloth meets the requirements.
