ABSTRACT OF THE DISCLOSURE The invention relates to a fibrous structure having a roughened surface and to a process for producing the same. The fibrous structure has surface irregularities whose structure is such that the distance between the adjacent projections is 0.01 to 0.7 micrometer and the area of the concave parts accounts for 0.1 to 0.8 square micrometer per square micrometer of the irregularities. The fibrous structure is produced by attaching fine particles to the fiber surface in an amount of 0.001 to 10 wt% based on the weight of the fiber, the fine particles having an average primary particle diameter smaller than 0.5 micrometer and being more inert than the fiber-constituting polymer base material in low-temperature plasma, and treating the fiber with low-temperature plasma, thereby forming projections which are larger than the average primary particle dia- meter. Upon dyeing, the fibrous stucture has a very good color depth. In addition, it gives a creak feeling better than silk does, and it has new uses.
