The Wrong Question: Why Asking 'Is Modal High Quality?' Misses the Point (And What Procurement Pros Should Ask Instead)

I've been in procurement for over a decade (12 years, specifically, managing a mid-sized budget for a high-end apparel brand), and if there's one question that reliably makes me sigh, it's this: "Is modal high quality?"

The question itself isn't bad. It's a perfectly natural starting point for someone new to textiles. But the way it's framed—as if "quality" is a single, fixed property of a fiber, like its melting point or tensile strength—is fundamentally backward. You end up comparing modal to cashmere, which is like comparing a swiss army knife to a scalpel. Both are tools. They do not do the same job.

The assumption behind the question is: Fiber A is high quality, Fiber B is low quality. The reality is: High quality execution of Fiber B often outperforms low quality execution of Fiber A for a specific application. The causation runs the other way. You don't start with the fiber and ask if it's good. You start with the garment, the use case, the price point, and then ask which fiber construction delivers the required performance at the target cost.

So, let's stop asking the wrong question. Here's a practical, 5-step checklist I built over years of auditing fabric specs (and getting burned a few times) to evaluate a fabric's true quality—and whether it's right for you.

Who This Checklist Is For

This isn't for designers who already have a deep material science background. This is for the rest of us: procurement managers, production coordinators, or brand owners who need a quick, defensible framework to evaluate a fabric swatch or a supplier's offering. It takes about 30 minutes to run through the full checklist on a new fabric (assuming you have a sample).

Let's get into it.

Step 1: Forget the Fiber Name. Look at the Construction.

This is step one for a reason. People get hypnotized by fiber names. "Oh, it's Loro Piana cashmere!" Great. But cashmere can be woven or knitted. It can be a flimsy single-ply or a dense, durable two-ply. The brand name gives you a quality ceiling, but the construction defines the floor.

The check: Ask for the GSM (grams per square meter) or fabric weight, and the yarn ply. For a cashmere dress—like the loro piana cashmere dress—a high-quality option will typically be around 200-250 GSM, often in a two-ply construction. A "cheap" cashmere dress might be 170 GSM, single-ply, and will pill and lose shape in a season. The fiber is the same. The construction is not.

Real-world example: Last year, I had a supplier pitch me on a "silk" blouse. The fiber content was 100% silk. But the weave was so loose it was almost transparent, and the GSM was laughably low for tailored wear. It wasn't a quality issue. It was a construction for a specific end-use issue. The silk was fine. The blouse was not.

Step 2: Analyze the Finish, Not Just the Hand Feel

Everyone loves a soft hand feel. But that's a trap. Softness can come from fiber (like cashmere) or from chemical treatments (like excessive silicon softeners) that wash out after three cycles.

The check: Look for the finish. Is it a matelasse? A matelasse upholstery fabric, for example, relies on a complex double-weave construction for its pattern and texture. The quality isn't just in the yarn; it's in the precision of the weave and the stability of the finish. Rub the fabric vigorously. Does it snag or distort? That's a sign of poor finishing, regardless of the fiber content.

(Note to self: I really should do a formal test comparing fabric durability after 20 washes. That's a data project for next quarter.)

Step 3: Check the Dye and Colorfastness (The Cheapest Test You Can Do)

This is the most frustrating part of fabric evaluation: you can't tell dye quality from a swatch. You'd think a high-priced fabric would have good colorfastness, but that's not always the case—especially with reactive dyes versus cheap direct dyes.

The check: Take a white, damp cloth and rub it firmly on the fabric for 10 seconds (this is called the crocking test, but a simplified version works for quick assessments). If there's significant color transfer, red flag. Then, cut a small piece and put it in hot water with a drop of detergent for 15 minutes. Did the color bleed? That's a no-go for anything that will be laundered.

Avoiding a trap: A vendor once told me their fabric had "excellent colorfastness." I tested it. It bled badly. The sales rep was probably sincere, but the supplier's quality assurance was not. The surprise wasn't the poor quality. It was how much time we wasted chasing a vendor who couldn't admit they had a production problem.

Step 4: Evaluate the Specific Use Case (Not the Label)

This is where the "is modal high quality?" question finally gets answered. Modal is a semi-synthetic fiber made from beech tree pulp. It's soft, absorbent, and drapes well. For a modern toddler bedding set, a high-quality modal (like Lenzing Modal) is excellent. It's breathable, durable enough for frequent washing, and soft against sensitive skin. High quality for that use case.

But for a tailored blazer? Modal lacks the structural integrity and memory of wool. It would wrinkle, lose shape, and look sloppy. The same fiber, different contexts.

The check: List the 3 most critical performance attributes for your end product. Examples:

• Durability: Will it be washed 50+ times? (Yes for bedding. Not always for a dress.)
• Drape vs. Structure: Does the fabric need to hold a sharp crease or flow like water?
• Breathability: For activewear or children's sleepwear, this is non-negotiable.

A high-quality fabric is one that excels at the specific attributes you need. Start with the needs, then assess the fiber and construction against them.

Step 5: Demand a Third-Party Test Report (The Highest Authority)

Personal touch is great. Gut feeling is okay. But the only real authority in fabric quality is a third-party test report. This is especially crucial when comparing something like a loro piana loom bag review (which is subjective) to actual performance data (which is objective).

The check: Ask for a fabric test report that includes:

• ASTM or ISO standards: Tensile strength, tear strength, pilling resistance.
• Colorfastness to washing, light, and crocking.
• Fiber composition analysis. (Verifies the claimed fiber percentages. Surprise, surprise, some cheaper suppliers under-declare man-made fibers.)

If a supplier can't or won't provide this, that tells you something. A lot of things, actually. "We tested it internally and it was fine" is not a test report.

In 2023, I audited our spending and found that 18% of our return issues were directly linked to fabrics with no third-party testing. We implemented a policy requiring a test report for any new fabric order over $2,000. That single step cut our fabric-related returns by over 60% in the next year.

Common Mistakes & Final Notes

The biggest mistake: Assuming a brand name guarantees quality for your specific need. A fabric labeled "Loro Piana" is likely excellent, but is it the right weight for summer sport coats? Is it the right drape for a soft blouse? The brand is a quality floor, not a guarantee of suitability.

The second mistake: Ignoring the finishing. A perfectly constructed fabric can be ruined by a poor finish. And a mediocre fiber can be significantly upgraded by a great finish.

Quick reference:

• Modal can be high quality (for bedding, underwear, soft dresses).
• Modal is usually not high quality (for tailored outerwear, upholstery, or anything requiring structure).

So, next time you look at a fabric, don't ask, "Is this high quality?" Ask the five questions:

1. What is the exact construction (GSM, ply, weave)?
2. What is the finish? How stable is it?
3. What is the dye quality?
4. Is this fiber/construction the right match for my specific use case?
5. Can I see the third-party test report?

That list, in that order, will serve you far better than a debate over the inherent 'quality' of a fiber name.
