Third-Party Test Reports, Published in Full in Chinese and English
A grey dyed spunlace fabric measured for color fastness, and a white undyed towel measured for absorbency, strength and microbial cleanliness. Both were tested by CTT, both are reproduced here in full, and both are yours to download.

Why we publish the paperwork
Most suppliers will send you a summary table. A summary is what someone typed; a report is what a laboratory signed. This page publishes the second kind, page for page, including the parameters where a limit is easy to miss.
There is a commercial reason too. When a buyer in Japan, Korea, the US or the Gulf compares three quotes for the same 200 by 200 millimeter towel, the price difference is usually explained by weight, fiber blend, wet strength and the amount of testing behind the shipment — and the last of those is the only one you cannot see. Publishing the full file is how we make it visible.
What follows is not marketing copy with a certificate attached. It is two documents read out in the open: what was submitted, which standard each parameter was measured against, what the laboratory found, and where the result sits relative to the limit.
Two samples, two completely different risk profiles
An undyed towel and a dyed one fail in different ways. That is why the two reports do not test the same things, and why reading them side by side is more useful than reading either one alone.
| Undyed white towel | Dyed grey spunlace | |
|---|---|---|
| Report | CTT2604013200CN (2026) | CTT2303060940EN (2023) |
| Sample as submitted | Pull-out thick facial towel, 200×200 mm, 600 g, branded retail pack | Jaroll spunlace non-woven fabric, grey, single piece |
| The failure it guards against | Poor absorbency, low wet strength, linting, residual sulphur from viscose processing, optical brighteners, microbial contamination | Dye migration — color bleeding into water, sweat, saliva and onto skin, plus restricted amines in the dyestuff |
| Standards applied | GB/T 40276-2021, Q/QDJR 006-2023, GB 15979-2024 | GB/T 40276-2021, GB 18401-2010 |
| Parameters reported | 21 (15 physical and chemical, 6 microbiological) | 8 |
| Outcome | All items conform | All items pass |
Color fastness is the whole reason a dyed fabric needs its own certificate. An undyed towel cannot fail a bleed test because there is nothing to bleed; a dyed one can, and in a wet wipe or a hotel towel that failure reaches the customer's skin.

Disclosure: two parameters — softness and linting coefficient — were subcontracted to Guangzhou Inspection Testing and Certification Group Co., Ltd (accreditation 220020349634), and the substitution is stated on page 3 of the report itself. We reproduce it here rather than edit it out.
The microbiological page most suppliers leave out
For a product that touches a face, then a bin, a microbiological result matters more than a gram-per-square-meter figure. GB 15979-2024 sets two ceilings and four prohibitions, and the report tests all six.
| Organism | Method | Limit | Result | |
|---|---|---|---|---|
| Total bacterial count | Annex B, B.2 | ≤ 200 CFU/g | < 5 | Conforms |
| Total fungal count | Annex B, B.7 | ≤ 100 CFU/g | < 5 | Conforms |
| Coliform bacteria | Annex B, B.3 | Not detected | Not detected | Conforms |

| Staphylococcus aureus | Annex B, B.5 | Not detected | Not detected | Conforms |
| Pseudomonas aeruginosa | Annex B, B.4 | Not detected | Not detected | Conforms |
A bacterial count reported as "less than 5 CFU per gram" is the lowest figure the method can express — the plate simply grew nothing countable. Against a 200 CFU/g ceiling that is the difference between a towel that is clean and a towel that is only within tolerance.
Report 2 — the grey dyed fabric, tested in 2023
Report no.CTT2303060940EN Sample received23 Mar 2023 Completed27 Mar 2023 Issued28 Mar 2023 Length5 pagesThis report exists because of color. A dyed fabric is asked one question the undyed one never faces: does the dye stay where it was put? Four different aggressors are used to answer it — water, acid and alkaline perspiration, dry and wet rubbing, and saliva — plus the two chemical screens that catch an unsafe dyestuff in the first place.
| Test item | Method | Requirement | Result | |
|---|---|---|---|---|
| Peculiar odour | GB 18401-2010 §6.7 | No peculiar odour | None | Pass |
| Color fastness to water — change / staining | GB/T 5713-2013 | ≥ 4 | 4-5 · wool 4-5 · viscose 4-5 | Pass |
| Color fastness to perspiration, acid — change / staining | GB/T 3922-2013 | ≥ 4 | 4-5 · wool 4-5 · viscose 4-5 | Pass |
| Color fastness to perspiration, alkaline — change / staining | GB/T 3922-2013 | ≥ 4 | 4-5 · wool 4-5 · viscose 4-5 | Pass |
| Color fastness to rubbing — dry / wet | GB/T 3920-2008 | ≥ 4 | Dry 4-5 · Wet 4 | Pass |
| Color fastness to saliva — change / staining | GB/T 18886-2019 | ≥ 4 | 4-5 · wool 4-5 · viscose 4-5 | Pass |
| pH value | GB/T 7573-2009 | 4.0 – 7.5 | 6.6 | Pass |
| Formaldehyde — mg/kg | GB/T 2912.1-2009 | ≤ 20 | Not detected (RL 20) | Pass |
| Azo dyes, 24 substances — mg/kg | GB/T 17592-2011 & GB/T 23344-2009 | ≤ 20 | All not detected (RL 5) | Pass |
Grading scale, as printed: grade 5 negligible or no change; grade 4 slightly changed or stained; grade 3 noticeably; grade 2 considerably; grade 1 much changed or heavily stained. Wet rubbing at grade 4 is the only figure in this report that sits exactly on the minimum rather than above it — which is normal for a wet-rub test and worth knowing before you specify a darker shade.
Reading the numbers, without the sales voice
Three results in the 2026 report are worth slowing down for.
Absorbency has real headroom
The standard asks a soft towel to sink within 5 seconds and to hold at least 500 per cent of its own weight. This sample sank in 1.37 seconds and held 798 per cent — roughly 60 per cent more liquid than the floor. That is what a 600 gram, 200 millimeter square, 100 per cent viscose towel is supposed to do; it is also why the same construction is used for salon and spa work where a towel is expected to finish a job in one pass.
Wet strength is the number that decides the complaint rate
Dry tensile strength of 75.3 N machine direction and 127.2 N cross direction looks impressive but is not the useful figure. Wet strength is: 42.7 N and 66.9 N against a 12.0 N minimum. A towel that tears in the hand while wet becomes a customer complaint, not a datasheet problem.
Residual sulphur and optical brighteners are the quiet ones
Viscose is made through a xanthation process, so residual sulphur is a genuine by-product question rather than a theoretical one — reported as not detected, against a limit of 10 mg per 100 g. Optical brighteners are prohibited outright for this product class; also not detected. Neither number appears on a typical quotation sheet, and both are the first things a Japanese or Korean buyer asks about.
One caveat we will not bury. A report describes one sample on one date. It is evidence of capability, not a guarantee attached to every future carton. For a new order, ask us to submit a fresh sample against your target market and specification — GB/T 40276, EN 1644, ISO 9073 or an internal standard — and the certificate will match the goods you actually receive.
Two small differences you will notice on the documents
Anyone comparing the two files closely will spot two mismatches. Neither is a discrepancy; both have a one-line explanation.
The name on the earlier report
The legal Chinese name is 青岛佳柔卫生用品有限公司, registered in English as QINGDAO JAROLL HYGIENE PRODUCTS CO., LTD. The 2023 report was issued to the company under the English rendering in use at that time; it is the same legal entity, and the name printed on the 2026 report is the one we use now. Where a formal document requires the registered English name, it is supplied with the business licence.
The factory moved
The 2023 report lists Xinyi Industrial Park, No. 1179 Lingang Road, Huangdao District, Qingdao. The 2026 report lists No. 4515 Jiaozhouwan East Road, Building 1, Huangdao District, Qingdao, which is the current production site. The relocation is the only reason the addresses differ; the applicant and the manufacturer are the same company in both documents.
There is a third difference worth naming: the two reports come from two legal entities inside the same CTT group — Guangdong for the 2026 file, Fujian for the 2023 file — which is why the CMA and CNAS numbers on the covers differ. Both are accredited laboratories; the numbers belong to the laboratory, never to the manufacturer.

Need the unwatermarked originals? For tenders, audits and regulatory filings we send the original PDFs plus the laboratory's online verification link. Write to sales@jaroll.com with the report number and your company name. Both reports can also be verified directly with the issuing laboratory using the number and QR code on each cover.
Questions buyers actually ask
Are these reports issued by an independent laboratory?
Yes. Both are CTT (Consumer Testing Technology) documents. The 2026 report was issued by Guangdong Consumer Testing Technology Co., Ltd in Dongguan; the 2023 report by Fujian Consumer Testing Technology Co., Ltd in Quanzhou. Neither laboratory is affiliated with Jaroll.
What do CMA, CNAS and ilac-MRA actually mean?
CMA is China's compulsory accreditation for a testing body that issues legally valid data. CNAS is the national accreditation body and a signatory to the ILAC Mutual Recognition Arrangement, which is what the ilac-MRA mark on the cover signifies: results from an accredited laboratory are recognised by counterpart bodies in other signatory economies. The numbers to check are CMA 201819001289 and CNAS L3068 on the 2026 cover, and CMA 211320110204 and CNAS L7220 on the 2023 cover.
Why is the 2023 report shorter than the 2026 one?
Because the brief was narrower. The 2023 file was a color and chemistry screen for a dyed fabric: eight items, four fastness tests. The 2026 file is a full product release for a white towel against three standards, including mechanical performance and microbiology. Different questions, not different rigour.
Does an older report still count?
It counts as evidence of what that sample did on that date against the standards then current. Standards are revised — the 2026 report already tests against GB 15979-2024, which post-dates the 2023 file. If your market or your customer requires current-year data, ask for a fresh submission rather than relying on the older document.
Can I use the watermarked PDF in a tender?
Usually not — many tender panels require an unaltered document. Ask us for the original with the laboratory's verification link; we issue it to verified buyers at no cost.
Will you test against our standard instead of GB?
Yes. The same samples can be submitted against EN 1644, ISO 9073 series, ASTM D5034 or your own specification, at an accredited laboratory of your choosing or ours. Testing scope and lead time are quoted with the order.
