How We Test Our Fabric

Why we describe our process rather than just claim quality

"Wash-fast" and "shrink-resistant" are easy words to print on a spec sheet. What actually backs them up is a process: a fabric checked at each stage against a known standard, not just dyed and shipped. This guide sets out what that process looks like for Benny Cotts fabric, plainly, so you can judge it rather than take it on faith. For properties we do not treat for, such as those in water-repellent, oil-repellent and anti-static finishes, we say so rather than tick the box.

See our guide on how to vet a uniform fabric supplier for the questions worth asking any mill; this is our own answer to those questions in detail.

Where each stage happens

Weaving is ours; dyeing and finishing run through processing partners we've worked with and hold to our standard, rather than through whichever mill or lot happens to be available.

What we check on every batch

Four checks repeat on every batch that goes out under the Benny Cotts name.

• Composition: confirming the fiber blend matches what's on the spec sheet, since this is the line everything else is judged against.
• GSM: a swatch is weighed to confirm the fabric sits within its stated weight range.
• Colour fastness: the dyed batch is checked against washing, light and rubbing, so a shade holds under real institutional laundering, not just under a shop light.
• Shrinkage: a swatch is measured before and after a standard wash cycle to confirm the fabric stays within its finished tolerance.

Why a locked shade standard matters more than a one-off check

A single good test result on one batch is not the same as consistency across years of reorders. When a custom shade is approved, we hold a physical reference for it and match every future batch of that program against the same standard, rather than testing each order in isolation and hoping the mill's next lot happens to land close. See our guide on dye-lot consistency for why this matters more for uniform programs than for a one-off purchase.

What this looks like from the buyer's side

• A written spec sheet with every fabric: composition, GSM, width, weave, colour and finish.
• Swatches and shade cards available on request before you commit to a program quantity.
• A reference standard held against your approved shade, so reorders are checked against it rather than against whatever a fresh lot produces.
• A straight answer if you ask what's woven in-house versus handled by a processing partner.

What we hold and what we don't

We're ISO 9001:2015 certified for our quality management system. Beyond that, we describe our own testing process here rather than citing a third-party lab accreditation for individual batch results, because we don't hold one to name. What we can stand behind is the process above: consistent weaving, dyeing and finishing checked against an approved standard through partners we work with regularly, on every batch.

FAQ

Frequently asked questions

Do you weave and finish fabric entirely in-house?

We weave at our own unit in Atoon, Bhilwara. Dyeing and finishing run through trusted processing partners in the region, checked against our approved standard rather than left to whatever a lot happens to produce.

What do you check before a batch ships?

Composition, GSM, colour fastness (wash, light and rubbing) and shrinkage, all checked against the spec sheet and, for custom shades, against our approved reference standard.

Are you ISO or lab-accredited?

We're ISO 9001:2015 certified for our quality management system. We don't hold a separate third-party lab accreditation for individual batch testing, so we describe our actual testing process here instead. Ask us directly for current certification status if that's a requirement for your program.

Can I see a test result or swatch before ordering in bulk?

Yes. Swatches and shade cards are available on request, and we're glad to walk through the spec and testing detail for any fabric before you commit to volume.

How do you make sure a shade matches on a reorder months later?

When a custom shade is first approved, we hold a physical reference standard for it. Every future batch of that program is checked against that same physical standard, not against whatever the last dye lot happened to produce, which is what keeps a reorder consistent with the original.

What does a Benny Cotts spec sheet actually include?

Every fabric comes with a written spec sheet covering composition, GSM, width, weave, colour and finish. It is the same document we test batches against, so what you receive should match what is written down.
