 ★竹を原料としたものであっても、化学的操作により一旦液状にした後に繊維に再生した

ものは品質表示法上はレーヨンとなり、竹繊維の表示はできません。

 竹を開繊して得られた繊維は、指定外繊維(竹繊維)と表示することができますが、竹繊

維は長さ約２㎜と短い繊維であり、紡績によって一般の衣料用糸とすることは困難です。


と明示されています。

竹は背が高い植物ですが、竹本来の繊維長は非常に短いのです。
ですから古来より繊維として利用されていなかったのですね。

How to Avoid Bamboozling  

Your Customers 

Marketers looking to provide more environmentally friendly choices to consumers 

may have heard about bamboo, which has been recognized for its ability to grow 

quickly with little or no need for pesticides. But when it comes to textile products made 

from bamboo, that’s not the whole story. 

The truth is, most “bamboo” textile products, if not all, really are rayon, which 

typically is made using environmentally toxic chemicals in a process that emits 

hazardous pollutants into the air. While different plants, including bamboo, can be used 

as a source material to create rayon, there’s no trace of the original plant in the finished 

rayon product. 

If you make, advertise or sell bamboo-based textiles, the Federal Trade 

Commission, the nation’s consumer protection agency, wants you to know that unless 

a product is made directly with bamboo fiber ― often called “mechanically processed 

bamboo” ― it can’t be called bamboo. Indeed, to advertise or label a product as 

“bamboo,” you need competent and reliable evidence, such as scientific tests and 

analyses, to show that it’s made of actual bamboo fiber. Relying on other people’s 

claims isn’t substantiation. The same standard applies to other claims, like a claim that 

rayon fibers retain natural antimicrobial properties from the bamboo plant.  

If you sell clothing, linens, or other textile products, you’re responsible for making 

truthful disclosures about the fiber content. If your product isn’t made directly of 

bamboo fiber ― but is a manufactured fiber for which bamboo was the plant source ― 

it should be labeled and advertised using the proper generic name for the fiber, such as 

rayon, or “rayon made from bamboo.” 

Any claims you make about your textile products have to be true and cannot be 

misleading. As the seller, you must have substantiation for each and every claim ― 

express and implied ― that you make.
