Just lately, the scientists within the GH Textiles Lab observed an alarming pattern: A rising variety of bedding and clothes manufacturers had been claiming that their merchandise had been manufactured from bamboo, eucalyptus or different tree fibers — and shoppers appeared , primarily based on the expansion in on-line searches. From their expertise, our consultants knew these merchandise couldn’t include any hint of the vegetation promoted within the claims, so after thorough analysis we chosen a large assortment of things for extra evaluation. Listed here are the main points and the outcomes of the investigation:

How We Examined

Our scientists zeroed in on over 50 merchandise clearly marketed as being manufactured 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 outdoor lab for fiber-identification testing. The end result: For all 10 gadgets, the lab couldn’t detect any hint of the claimed vegetation or bushes within the closing material.

What Are the Merchandise Really Made Of?

All 10 merchandise we examined contained rayon. Rayon is the umbrella time period for fibers manufactured from plant cellulose. Varieties of rayon embrace viscose, lyocell and modal. Whereas they’re related, “they fluctuate primarily based 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 material 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 not exist within the closing material,” says Sachs. “All that’s left is cellulose, which is then processed with extra chemical compounds and changed into 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 vegetation like bamboo and eucalyptus develop as robust stalks and tree wooden. When cotton will get processed to make a completed material, the fiber isn’t chemically modified and its general construction stays the identical. So when a lab examines cotton from sheets or clothes underneath a microscope, the unique cotton fiber continues to be seen.

What the Legislation Says

The Federal Commerce Fee (FTC) requires manufacturers to make use of the manufactured title for rayon fibers corresponding to viscose and lyocell. It does permit manufacturers to reference the uncooked materials whether it is included together with the generic title — 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 record the correct title in positive print or on a garment’s label, however that’s not sufficient to adjust to laws. A press release for companies on the FTC web site explains: “If it’s not made straight of bamboo fiber, don’t name it bamboo. Not wherever, not any manner.” In the identical assertion, the FTC factors out: “Some corporations appear to suppose 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 offers a concise “Learn how to Keep away from Bamboozling Your Prospects” information on its web site to stop 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 relating to false claims involving fibers from bushes like eucalyptus and beechwood.

Why It’s a Downside

Describing a product’s fiber with a plant title as an alternative of the right time period can mislead buyers in quite a lot of methods, together with:


This tactic overstates a product’s eco-friendly qualities to drive gross sales. Bamboo rayon will not be as “inexperienced” as you suppose: 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 may be reused.

In addition to the environmental affect from chemical compounds within the manufacturing course of, materials derived from bushes might contribute to deforestation if they don’t seem to be correctly sourced. Whenever you store, you may examine 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 shoppers to buy a product for the fallacious 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 firstly, “the purified pulp comprises principally cellulose. All the opposite chemical compounds, corresponding to antimicrobials in bamboo, are eliminated.”

FTC legal professional Miriam Lederer tells Good Housekeeping that buyers 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 title in sure locations will not be sufficient, “as a result of shoppers would possibly make their buy choices earlier than seeing the total and correct fiber-content disclosure.”

The Cause It’s All over the place

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 doable 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 ideal job advertising and getting on shoppers’ radar, they might have much less understanding of how the product is made and the way to comply with U.S. laws.

Our Lab professionals additionally spoke with textile consultants from SGS, a number one worldwide supplier of testing and different validation companies. They agreed that entrepreneurs might be misled by suppliers about fiber content material and product specs, they usually urged manufacturers to confirm all claims earlier than relaying them to shoppers. Most necessary, “Claims have to 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 schooling on product labeling.”

How Manufacturers Responded

We reached out to all 10 corporations to allow them to find out about our findings and to find out about their validation processes. Inside days, six manufacturers took steps towards fixing the errors, corresponding to including “viscose” or “lyocell” to their web site descriptions and altering product names. A number of claimed they’d had no concept the unique vegetation weren’t within the materials and mentioned they hadn’t examined their merchandise themselves. Some mentioned they knew the plant was solely the uncooked materials however didn’t notice they weren’t allowed to discuss with the material utilizing a plant title. 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 gadgets we examined. We requested these manufacturers to share how they validate the advertising claims and whether or not they had thought of FTC laws.

Simple Methods to Store Smarter

Maintain an eye fixed out for particular fiber names as an alternative of unsubstantiated eco claims. For a legitimately sustainable possibility, search for Lenzing fibers, corresponding to its Tencel-branded lyocell. It’s sourced from responsibly managed forests and made by way of 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 comfortable, sustainably made rayon choices, you may 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 reality, a number of of our top-tested merchandise include rayon. Simply be cautious of plant-content claims.
