Next, dyeing was carried out under the same conditions as in Example 1,
Drying was performed. When the tear strength in the longitudinal direction of the obtained woven fabric was measured, there was no problem with the woven fabric having a weight of 1000 g, and a feeling and glossiness unique to cellulose filaments were obtained, but the cotton husk remained on the surface.
