Rayon
Rayon is a regenerated cellulose fiber made from materials such as wood pulp, and is used in apparel and linings for its smooth feel, moisture absorption, and drape.

Definition and Overview
Rayon is a regenerated fiber made by once dissolving cellulose contained in wood pulp and then reforming it into fiber. Because it has a silk-like luster and smoothness, it is widely used in woven fabrics, knit fabrics, linings, and apparel materials.
Viscose is one of the representative manufacturing methods and names for rayon. In material labeling and fabric distribution, it may be written as rayon or as viscose, and the blend ratio and processing details are also checked together.
Features
Rayon has moisture absorbency and is a material that easily gives a dry touch and flexible drape that follows body movement. In filament yarn, it can express an elegant luster, while in spun yarn it can create a soft, calm appearance.
On the other hand, its strength tends to decrease when it absorbs moisture, so care is needed regarding shrinkage, distortion, and wrinkling caused by friction and washing. In addition to being used alone, it is also sometimes blended or union-woven with polyester, nylon, cotton, and other fibers to improve durability and ease of handling.
- It tends to have a smooth texture with good drape.
- It has moisture absorbency and is also used for applications that seek less stuffiness.
- Because it can become delicate when wet, checking the care instructions is important.
Main Applications
It is used for garments that take advantage of a soft texture and drape, such as blouses, shirts, dresses, skirts, pants, and cut-and-sew items. From lightweight to medium-weight materials, a wide range of expressions is possible depending on the weaving or knitting method and yarn usage.
It is also used for linings and accessory materials for women's clothing, taking advantage of its smoothness and feel against the skin. Fabrics with a cool feel are suited to spring and summer apparel, but depending on use with other fibers or processing such as brushing, they are adopted year-round.
Selection and Handling Notes
When selecting a fabric, check not only the rayon blend ratio but also whether it is woven or knit, the yarn type, fabric weight, structure, and finishing process. Even with the same rayon blend, a lightweight georgette and a medium-weight twill differ greatly in sheerness, drape, and ease of sewing.
Before sewing, perform a test wash under the same conditions as the product and check shrinkage, color fading, wrinkling, and skewing. During cutting and sewing, the fabric may stretch or slip easily, so align the grain and, if necessary, consider interfacing and stabilizing the seam allowance.
Wash according to the product's care instructions. Avoid strong friction, long soaking, and strong spin-drying, as these may damage the texture and dimensions; after washing, it is basic practice to reshape the item and dry it flat or hung properly.
Differences from Similar Terms
Lyocell and modal are also regenerated fibers made from wood-derived cellulose, but their manufacturing methods and commonly seen properties differ from rayon. It is important not to judge performance from the material name alone, but to check the blend ratio, fabric specifications, and care instructions.
Cupro is also a type of regenerated cellulose fiber, and it differs from rayon in that it mainly uses raw material derived from cotton linters. Polyester, on the other hand, is a synthetic fiber that includes petroleum-derived components, and its moisture absorbency and behavior when wet differ from rayon.
Frequently Asked Questions
Can rayon be washed at home?
Whether it can be washed depends on the fabric structure, blended fibers, dyeing and finishing, and product design. Rayon tends to become delicate when wet, so always follow the care instructions. Before mass production, wash tests are carried out on the product to check for shrinkage and changes in texture.
Are rayon and viscose the same?
Viscose is a representative manufacturing method and name related to rayon. In distribution, viscose rayon may simply be called viscose. However, the labeling rules for material names and care information may differ by sales region and product category, so the displayed information should be checked.
What should be noted when sewing rayon fabric?
Lightweight rayon fabrics and fabrics with strong drape can shift easily during cutting and stretch easily during sewing. Before cutting, align the grain and check the needle, thread, and stitch conditions with a test seam. If necessary, use interfacing and stay tape to stabilize the seam allowance.
