Ro
Ro is a lightweight woven fabric with sheerness and breathability, in which plain weave sections and ro marks that create gaps by twisting the warp threads are arranged alternately.

Definition and Overview
Ro is a woven fabric that creates open ro stripes at regular intervals by twisting warp threads together between the plain weave that forms the ground structure. The ro stripes are generally arranged in horizontal lines, but their placement and spacing vary by design. It is the name of a weaving method, not a material name.
The ro structure crosses warp threads with each other to secure the weft, giving structural stability even to the open areas. It is woven from a variety of fibers according to the intended use, including silk, cotton, linen, rayon, and polyester.
Features
Because of the contrast between the plain weave sections and the sheer ro stripes, it has the look of fine horizontal bands and a light, neat appearance. Sheerness, firmness, and drape vary greatly depending on the density of the ground sections, yarn thickness, and spacing of the ro stripes.
Because it has open areas, it allows air to pass through easily and is a textile that readily provides a cool feel suitable for hot weather. On the other hand, the fabric color, skin, and seam allowances may show through, so in tailoring it is checked together with the lining, dress shield, and underwear color.
Main Applications
Ro is widely used in Japanese-style clothing, such as summer kimono, haori, and fabrics for obi accessories. It is easy to achieve both a formal impression and a cool-looking appearance, and depending on the application, solid, dyed patterns, and woven pattern effects are chosen.
In Western-style clothing, it is used for layered looks that take advantage of its sheerness, as well as blouses, dresses, skirts, and dresses. Because it is a lightweight fabric, it is better suited to light garments and design-focused sections than to applications that require strong durability on its own.
How to Choose and Handling Notes
When selecting it, check the material, spacing of the ro stripes, fabric thickness, sheerness, and density of the ground weave. Even among ro fabrics, the hand feel, drape, and dimensional change after washing differ depending on the type of yarn and finishing, so it is important to check samples under conditions close to the intended use.
Shrinkage and changes in texture from washing vary depending on the material and finish. Follow the care label and perform washing tests before mass production. In sewing, use needles for lightweight fabrics and fine thread, and prevent thread pulls caused by a stiletto or a coarse needle, as well as uneven stitching around the ro stripes.
- Before cutting, check the grainline and the straightness of the ro stripes.
- Assume sheerness in seam allowances and facings, and consider the finishing method.
- Iron at a temperature suitable for the material, using a pressing cloth, and avoid flattening and shine.
Differences from Similar Terms
Sha is a lightweight fabric in which a sheer woven structure created by leno weaving continues across the entire textile. Ro, by contrast, alternates plain weave sections with ro stripes, so the sheer areas appear at intervals and it tends to have a banded appearance.
Gauze is a fabric name that expresses a soft, airy texture created by a coarse plain weave or similar structures. Ro refers to a structural characteristic in which warp threads are twisted together to form ro stripes. Voile, meanwhile, is a crisp lightweight fabric made with high-twist yarn and is a separate category from whether or not it has ro stripes.
Frequently Asked Questions
How can ro and sha be distinguished?
Ro is a woven fabric in which ro stripes appear between plain weave sections, and the sheer parts are easy to see as lines or bands. Sha has a sheer woven structure from leno weaving that continues throughout, so the sheerness is more uniform and overall. However, appearance varies depending on the pattern and density, so it should be checked with a weave sample.
Can ro be washed at home?
Whether it can be washed depends not on the ro structure itself but on the type of fiber, dyeing, finishing, and sewing specifications. In particular, silk and similar materials may shrink or change texture when washed with water. Always check the care label, and before productization confirm the dimensions and appearance after washing.
