The Fact About Bamboo and Eucalyptus Materials

Lately, the scientists within the GH Textiles Lab seen an alarming pattern: A rising variety of bedding and clothes manufacturers had been claiming that their merchandise had been made from bamboo, eucalyptus or different tree fibers — and customers appeared , based mostly on the expansion in on-line searches. From their expertise, our specialists knew these merchandise couldn’t comprise any hint of the crops promoted within the claims, so after thorough analysis we chosen a large assortment of things for added evaluation. Listed here are the small print and the outcomes of the investigation:

How We Examined

Our scientists zeroed in on over 50 merchandise clearly marketed as being made from bamboo, eucalyptus or beechwood fibers, together with clothes, footwear and bedding. We purchased 10 of them, reviewed their labels and despatched them to an out of doors lab for fiber-identification testing. The outcome: For all 10 objects, the lab couldn’t detect any hint of the claimed crops or bushes within the remaining cloth.

What Are the Merchandise Truly Made Of?

All 10 merchandise we examined contained rayon. Rayon is the umbrella time period for fibers manufactured from plant cellulose. Sorts of rayon embody viscose, lyocell and modal. Whereas they’re comparable, “they range based mostly on the manufacturing steps,” explains Lexie Sachs, GH Institute textiles director and head fiber scientist. It may be complicated as a result of the method of creating cloth from bamboo, eucalyptus or one other tree does begin with the plant. “However the uncooked plant supplies are chemically dissolved to the purpose that they now not exist within the remaining cloth,” says Sachs. “All that’s left is cellulose, which is then processed with extra chemical compounds and become fibers.” In different phrases, the merchandise are derived from bamboo or bushes, however not made of them.

How Is Cotton Totally different?

Cotton grows as a fiber, whereas crops like bamboo and eucalyptus develop as powerful stalks and tree wooden. When cotton will get processed to make a completed cloth, the fiber isn’t chemically modified and its total construction stays the identical. So when a lab examines cotton from sheets or clothes beneath a microscope, the unique cotton fiber continues to be seen.

What the Regulation Says

The Federal Commerce Fee (FTC) requires manufacturers to make use of the manufactured identify for rayon fibers reminiscent of viscose and lyocell. It does permit manufacturers to reference the uncooked materials whether it is included together with the generic identify — e.g., “viscose from bamboo” — however corporations are skipping this qualifier in product names and advertising.

“If it’s not made straight of bamboo fiber, don’t name it bamboo… That is a mistake.”

Some manufacturers checklist the correct identify in advantageous print or on a garment’s label, however that’s not sufficient to adjust to laws. An announcement for companies on the FTC web site explains: “If it’s not made straight of bamboo fiber, don’t name it bamboo. Not anyplace, not any approach.” In the identical assertion, the FTC factors out: “Some corporations appear to assume that in the event that they modify their content material disclosures to precisely learn ‘rayon,’ they’re free to make use of the phrase ‘bamboo’ in product titles and descriptions. That’s a mistake.”

The FTC gives a concise “Tips on how to Keep away from Bamboozling Your Prospects” information on its web site to forestall manufacturers from making this sort of error. It has sued some corporations for false bamboo labeling, however this has solely scratched the floor; it hasn’t but sued concerning false claims involving fibers from bushes like eucalyptus and beechwood.

Why It’s a Drawback

Describing a product’s fiber with a plant identify as an alternative of the proper time period can mislead customers in a wide range of methods, together with:


This tactic overstates a product’s eco-friendly qualities to drive gross sales. Bamboo rayon is probably not as “inexperienced” as you assume: Harsh chemical compounds are sometimes used to make it. Lyocell is taken into account a greater possibility than viscose as a result of the solvent used to make it’s much less poisonous and could be reused.

Apart from the environmental influence from chemical compounds within the manufacturing course of, materials derived from bushes might contribute to deforestation if they are not correctly sourced. While you store, you’ll be able to test whether or not corporations adjust to FSC or PEFC requirements to make sure the bushes are coming from sustainably managed forests.


“Bamboo,” “eucalyptus” or “beechwood” might sound extra luxurious and particular than rayon, main customers to buy a product for the improper causes.

False Guarantees

Manufacturers typically spotlight properties of the plant or tree of their advertising, as in saying bamboo is of course antimicrobial. When the plant will get chemically dissolved, it loses all hint of these traits. Anil N. Netravali, Ph.D., a professor of fiber science and attire design at Cornell College, explains that whatever the plant used at the beginning, “the purified pulp accommodates principally cellulose. All the opposite chemical compounds, reminiscent of antimicrobials in bamboo, are eliminated.”

FTC lawyer Miriam Lederer tells Good Housekeeping that customers ought to have the ability to see clearly {that a} product has attributes of rayon as an alternative of the uncooked materials. She says having the fiber identify in sure locations is probably not sufficient, “as a result of customers may make their buy selections earlier than seeing the complete and correct fiber-content disclosure.”

The Motive It’s In all places

With the rise of start-ups and direct-to-consumer manufacturers, bedding and attire corporations are sometimes run by entrepreneurs as an alternative of individuals with backgrounds in textiles. “It’s potential that manufacturers don’t even notice they’re making a mistake as a result of suppliers present them with info that’s both inaccurate or misinterpreted,” says Sachs. Whereas the manufacturers do an important job advertising and getting on customers’ radar, they could have much less understanding of how the product is made and how you can comply with U.S. laws.

Our Lab professionals additionally spoke with textile specialists from SGS, a number one worldwide supplier of testing and different validation companies. They agreed that entrepreneurs could possibly be misled by suppliers about fiber content material and product specs, they usually urged manufacturers to confirm all claims earlier than relaying them to customers. Most necessary, “Claims should be substantiated by technical paperwork to show they’re true, correct, related and verifiable,” says Min Zhu, Ph.D., technical director for softlines at SGS North America.

Even when suppliers present correct info, it might probably simply be distorted. “Strong storytelling and the disconnect between designer and advertising can result in incorrect labeling and communications,” says Tricia Carey, director of world enterprise growth at Lenzing, a preferred fiber producer. “We see extra rising manufacturers that want training on product labeling.”

How Manufacturers Responded

We reached out to all 10 corporations to allow them to learn about our findings and to find out about their validation processes. Inside days, six manufacturers took steps towards fixing the errors, reminiscent of including “viscose” or “lyocell” to their web site descriptions and altering product names. A number of claimed they’d had no thought the unique crops weren’t within the materials and stated they hadn’t examined their merchandise themselves. Some stated they knew the plant was solely the uncooked materials however didn’t notice they weren’t allowed to check with the material utilizing a plant identify. Two manufacturers didn’t reply.

The place We Discovered Claims

These examples present widespread locations to identify mislabeled rayon fibers, together with particular cases from objects we examined. We requested these manufacturers to share how they validate the advertising claims and whether or not they had thought-about FTC laws.

Straightforward Methods to Store Smarter

Hold an eye fixed out for particular fiber names as an alternative of unsubstantiated eco claims. For a legitimately sustainable possibility, search for Lenzing fibers, reminiscent of its Tencel-branded lyocell. It’s sourced from responsibly managed forests and made through a greener course of with safer chemical compounds and fewer waste. If manufacturers use it, it’s usually listed on their web sites and labels.

GH Lab–Accepted Picks

For those who’re on the lookout for smooth, sustainably made rayon choices, you’ll be able to belief that these merchandise use responsibly sourced Tencel fibers with out going overboard on their claims.

Backside Line

The truth that these merchandise are mislabeled doesn’t imply they’re low high quality. In actual fact, a number of of our top-tested merchandise comprise rayon. Simply be cautious of plant-content claims.
