Yoryu (Wrinkle Crepe)
Yoryu is a woven fabric characterized by a dry touch and breathability, with fine warp-direction wrinkles on the surface, often created using strongly twisted threads.

Definition and Overview
Yoryu is a textile characterized by fine, vertical wrinkles running like willow leaves. These wrinkles are the uneven texture on the surface of the textile, and are often created by using highly twisted thread and taking advantage of its tendency to untwist.
Lightweight yoryu made with cotton is well known, but there are also versions made with rayon, polyester, and blended or union fabrics. Depending on the material, thread thickness, density, and finish, the degree of sheerness, drape, and wrinkle texture can vary greatly.
Features
The surface texture tends to reduce the area of contact between the textile and the skin, making it a fabric that is easy to wear with a dry, smooth feel. In lighter product numbers, lightness and breathability can also be expected, but actual water absorbency and quick-drying performance should be confirmed depending on the material and processing.
The vertical wrinkles give plain designs a rich appearance and create a natural, cool look. On the other hand, there can be individual differences and lot-to-lot variations in the shape and spacing of the wrinkles, and the way patterns and prints appear also differs from smooth textiles.
Main Applications
Yoryu is used for items that take advantage of lightness and a cool feel, such as shirts, blouses, dresses, and skirts. It is especially suitable for spring and summer apparel and for silhouettes with a relaxed fit.
Taking advantage of its easy drape against the skin, it is also used for nightwear such as pajamas and for innerwear. Since thin fabrics may be sheer, consider using lining, layering construction, or color selection according to the application.
Selection and Handling Notes
When selecting, confirm not only the material composition but also the direction and strength of the wrinkles, fabric width, fabric weight, sheerness, and dimensional change after washing. Because the wrinkles change the apparent width and length compared with a flat fabric, it is important to determine fabric consumption after checking the actual material in its natural state.
Washing, moisture, and heat may change the appearance and dimensions of the wrinkles. Before mass production, confirm shrinkage and appearance changes using the intended washing method, and if necessary perform fabric straightening or hot water treatment. Ironing with strong pressure may flatten the texture, so use a pressing cloth and handle it at a temperature suitable for the specifications.
During cutting, do not pull the fabric excessively; first align the wrinkles in their natural state, then lay out the fabric. During sewing, thin fabrics and fabrics with drape are prone to slipping, so adjust the needle, thread, and feed conditions through test sewing. Since the vertical wrinkles are noticeable, also check the grain line and how the parts will appear together.
- Check the care label and the fabric maker's handling conditions.
- Stabilize the fabric before and after cutting, and confirm the dimensions.
- Avoid measuring or pressing the fabric while the wrinkles are stretched out.
Differences from Similar Terms
Crepe is a general term used for fabrics with texture created by highly twisted thread and similar methods. Yoryu refers to the type characterized by fine wrinkles flowing in the vertical direction. However, in distribution, both names may be used together, as in yoryu crepe.
Seersucker also tends to provide easy wear against the skin through its uneven surface, but it mainly expresses relatively regular striped texture through differences in warp tension and weave structure. In contrast, yoryu is fundamentally characterized by fine vertical wrinkles created by the shrinkage of highly twisted thread.
Frequently Asked Questions
Is yoryu a fabric for summer?
Thin yoryu made with cotton and other materials is often used for spring and summer apparel because of its breathability and ease of wear against the skin. However, yoryu is a term related to weave structure and surface expression, and thickness and material vary widely. Whether it is suitable for autumn and winter should be judged by fabric weight, material, density, and finish.
Does yoryu shrink when washed?
Depending on the material, processing, and how the wrinkles are created, yoryu may change in dimensions and wrinkle appearance after washing. It is especially important to confirm shrinkage in fabrics containing natural fibers. Conduct washing tests before planning and sewing, reflect the shrinkage rate in the pattern and fabric consumption, and handle according to the stated care conditions.
What is the difference between yoryu and seersucker?
Both have uneven surfaces and are fabrics that are easy to wear against the skin, but the method of creating the uneven texture differs. Yoryu is basically characterized by fine vertical wrinkles that make use of the properties of highly twisted thread. Seersucker is characterized by creating relatively regular striped texture through differences in warp tension and weave structure.
