Iyo Kasuri

Definition and Production Area

Iyo Kasuri is a cotton textile that developed in and around Matsuyama in present-day Ehime Prefecture, which corresponds to the former Iyo Province. Kasuri refers to a technique in which yarns dyed in different colors are woven with the color boundaries intentionally offset to create a pattern with slightly blurred outlines.

Iyo Kasuri is a name that serves as both a production-area name and a textile name. For that reason, it is handled separately from fabric that simply prints a kasuri pattern and from kasuri textiles made in other production areas. When purchasing, it is important to confirm the production area, weaving location, and the method used to express the kasuri pattern.

History and Technique

Iyo Kasuri has been used for everyday clothing mainly with cotton as the primary material, and it developed as an important local textile industry. Today, because the number of people involved in production and the output volume are limited, bolts made with traditional techniques often have supply conditions that differ from those of ordinary mass-produced fabrics.

In pattern creation, the warp yarns, the weft yarns, or both are dyed separately before weaving. Because the process requires adjusting yarn positions to align the pattern, the outlines of the design show a soft variation created by handwork and weaving adjustments.

• Expressions that make use of the contrast between indigo and white are often seen.
• Repeated patterns such as geometric motifs, igeta lattice, and small kasuri motifs are used.
• The pattern may be formed using only the warp, only the weft, or both the warp and weft.

Typical Fabrics and Applications

A representative example is a fabric based on plain-woven cotton with a kasuri pattern. It is characterized by the combination of yarn dyeing and woven patterns, and the precision of the design, the fabric texture, thickness, and color usage vary depending on the maker and specifications.

Traditionally, it has been used for kimono and everyday wear. Today, it is also used for shirts, blouses, dresses, outer layers, bags, accessories, and interior items. In products, the cutting position and pattern matching are considered to make the most of how the pattern appears.

Points to Check When Purchasing

When planning and selling the item as Iyo Kasuri, confirm with the supplier the basis for using the production-area name. Clarify the weaving location, yarn dyeing and weaving processes, and whether it is handwoven or machine-woven, and make sure the wording in specifications and hangtags does not confuse it with plain kasuri-style fabric.

Confirm early whether small-lot production is possible, the minimum lot size, bolt length, standard width, and whether it is stock goods or made to order. Because production conditions may differ by pattern and color, check color differences, pattern misalignment, shrinkage, and appearance after washing with a sample bolt before mass production.

• Whether the production area and weaving location can be indicated
• Blend ratio of materials, weave structure, fabric width, fabric weight, and bolt length
• Pattern direction, pattern repeat, and pattern matching conditions during cutting
• Minimum lot size, possibility of additional production, and delivery time
• Quality information such as washing method, shrinkage, and color fastness to rubbing

Differences from Similar Terms

Kasuri is a general term for a technique or textile that creates patterns by weaving yarns dyed in different colors. Iyo Kasuri refers specifically to the production-area textile that developed in and around Matsuyama, Ehime Prefecture. Therefore, Iyo Kasuri is a type of kasuri, but not all kasuri is Iyo Kasuri.

Kurume Kasuri is also known as a cotton kasuri textile, but its production area and the background of its patterns and processes, which were developed in that region, are different. Also, while print applies a pattern to finished fabric, kasuri differs in that the pattern is generally formed by dyeing the yarns before weaving.
