Shine

Definition and Overview

Tekari refers to a condition where fibers, thread, or the surface of a textile reflect light and appear glossy. It may mean the look of a textile intentionally given a sheen, or a local change in appearance caused by wear, ironing, or friction, so the context needs to be checked.

The English word glazing may refer to a finish that gives a textile surface a strong sheen. In Japanese, tekari often refers not so much to an even luster created by processing, but rather to uneven shine that appears around the elbows, seat, or seam allowances, and is often treated as a problem.

Features and Appearance

Intentional tekari creates a smooth, bright surface feel, and the strength of the sheen changes depending on the lighting and viewing angle. High-density woven fabrics, textiles made with filament thread, and satin weaves are especially likely to show luster depending on the structure and the properties of the thread.

On the other hand, undesirable tekari occurs when the nap lies flat, the fiber surface becomes crushed, or heat or pressure is applied. It is especially noticeable on dark-colored textiles, and may look whitish because of the difference in reflected light from the surrounding area.

Main Applications

Textiles that make use of an even sheen are used for items that call for elegance or a flowing look, such as dresses, formal wear, blouses, skirts, and stage costumes. They range widely from light to medium-heavy weights, and applications vary depending on the weave, material, and thickness of the textile.

Attention to friction-induced tekari is important for trousers, uniforms, jackets, and coats, which are repeatedly subjected to pressure when sitting or bending at the elbows. Even brushed materials for autumn and winter may show changes in the pile as differences in sheen.

Selection and Care Notes

When selecting sheen as part of the design intent, check swatches from multiple directions for color, sheen strength, sheerness, and drape. Since the appearance changes depending on the lighting even with the same color, it is important to check the appearance of product samples including trims and seams.

If you want to avoid tekari, use a pressing cloth and adjust the iron temperature, pressure, and amount of steam to suit the textile. During sewing as well, strong pressing or excessive pressing can create differences in sheen around the seam allowances. Follow the care label for washing and cleaning, and handle the item with reduced friction.

Whether shrinkage occurs, and to what degree, depends not on tekari itself but on the material, structure, and finish. Check each textile for washability, shrinkage rate, and appearance changes caused by pressing, and it is safer to carry out trial sewing and washing tests before mass production.

Differences from Similar Terms

Sheen is a broad term for the reflection of light seen across the whole textile. Tekari is also used in the sense of sheen, but it may indicate a localized, unintended change in gloss. Satin weave is a weave structure that readily produces sheen, and is not a term for tekari itself.

Ciré finish and calendering are processes that use heat or pressure to smooth the surface and adjust sheen and hand feel. These are intentional finishes, but tekari may be used either as a process name or to describe an appearance phenomenon that occurs during use.
