[0030]

The present invention has the following excellent effects. The tubular fabric according to the present invention, on one side edge portion of the tubular body,
Since openings of a required length are arranged side by side at a required interval, this is attached to a curtain, a rod-shaped body is placed in a tubular body, and both ends of the tubular body are sealed,
The rod can be moved in and out through the required openings. Therefore, when necessary, the rod-shaped body can be removed from the tubular body to clean the curtain, and after the cleaning, the rod-shaped body can be slid into the tubular body through the opening and placed, whereby the pull-up curtain can be formed again. .

In addition, in the conventional pull-up type curtain, since both ends of the tube cannot be sealed by sewing or the like only after the rod is inserted into the tube, the bar is obstructed. As a result, work such as sewing cannot be carried out smoothly, and the work is troublesome, and the production efficiency of the pull-up curtain is poor. On the other hand, according to the present invention, both ends of the tubular fabric can be sealed by means such as sewing or fusion in a flat state where the rod-shaped body is not inserted. Therefore, there is an advantage that these operations such as sewing can be performed smoothly, and a pull-up curtain can be efficiently manufactured.

In particular, when the loose pieces are composed only of warp yarns or are formed of tape-like or cord-like materials, since there is no need to intersect these with weft yarns, the structure of the tubular fabric becomes simpler. The production efficiency of the tubular fabric can be improved.
