Bamboo Fiber
Bamboo fiber is a general term for fibers obtained from bamboo, including fibers made by mechanically processing bamboo into fibers and regenerated cellulose fibers made by dissolving and regenerating it.

Definition and Overview
Bamboo fiber refers to fibers derived from bamboo, but their properties vary greatly depending on the manufacturing method. Many products labeled “bamboo” or “bamboo rayon” in apparel textiles are regenerated cellulose fibers made by dissolving bamboo and reforming it.
Fibers obtained by physically breaking down bamboo are treated as plant fibers like linen. On the other hand, regenerated cellulose fibers are treated as a type of rayon, so in specification sheets and blended-ratio labels, confirm not only the raw material name but also the fiber name and manufacturing method.
Characteristics
Regenerated-cellulose bamboo fiber is a material that tends to be smooth, soft, and drapey. Its sheen varies depending on the yarn shape, knit or woven structure, and dyeing/finishing process, ranging from subtle to relatively lustrous.
It is sometimes used for garments that take advantage of moisture absorption, but performance such as water absorbency, quick-drying properties, and antibacterial properties cannot be determined from the fiber name alone. It is important to check the blended material, fabric weight, structure, post-processing, and test results.
Main Applications
It is used for cut-and-sew items, T-shirts, innerwear, loungewear, nightwear, shirts/blouses, dresses, and similar products that require softness and drape. It may also be blended with cotton, polyester, polyurethane, and others to adjust strength, dimensional stability, and stretchability.
It is often developed for relatively lightweight to medium-weight knits and woven fabrics, and is used not only for spring and summer items but also for year-round products that prioritize comfort against the skin. Seasonal suitability is determined not by the fiber name, but by textile thickness, structure, blend ratio, and finish.
Selection and Handling Notes
When selecting, confirm not only that it is bamboo-derived, but also whether it is a regenerated cellulose fiber or a plant fiber, the blend ratio, knit or woven structure, fabric weight, stretchability, and dimensional change after washing. In particular, regenerated-cellulose types may require caution when wet or when exposed to friction.
The degree of shrinkage, wrinkling, fuzzing, and color fading caused by washing differs by textile. Before mass production, perform washing tests and sewing tests, and determine the care label. For dark colors, also check rub fastness and consider color transfer when combined with light-colored items or when layered.
In sewing, for soft, stretch-prone knit fabrics, stretching during cutting, seam waviness, and seam stretching can occur. Align the grain before cutting, choose needles, thread, and sewing specifications suited to the fabric’s stretch, and use stay tape or other stabilization methods as needed.
Differences from Similar Terms
Rayon is a general term for fibers made by regenerating cellulose such as wood pulp. “Bamboo rayon,” made by regenerating bamboo as the raw material, is included in rayon, but not all materials made by mechanically fiberizing bamboo are called rayon.
Lyocell is also a fiber made by dissolving and regenerating cellulose, but its production process and classification differ from rayon. Likewise, linen and Ramie are natural fibers obtained from plant stems and similar sources, and are generally distinguished from bamboo-derived regenerated cellulose fibers.
Frequently Asked Questions
Are bamboo fiber and bamboo rayon the same?
They are sometimes used to mean the same thing, but strictly speaking they are different. Bamboo fiber refers to fibers derived from bamboo in general, while bamboo rayon refers to rayon made by regenerating bamboo-derived cellulose. When ordering, confirm the blend ratio label and manufacturing method.
Does bamboo fiber textile shrink?
Whether and how much it shrinks depends on the manufacturing method, blend ratio, structure, finishing process, and washing conditions. Since regenerated-cellulose textiles may change properties when they absorb moisture, confirm the shrinkage rate under the intended washing conditions before mass production and reflect it in the pattern.
Does bamboo fiber have antibacterial properties?
Antibacterial properties cannot be judged uniformly for products based solely on being bamboo-derived. Performance varies depending on the regeneration process, post-processing, and test conditions. When labeling antibacterial or deodorizing properties, it is necessary to check the test results and labeling basis for the target textile.
