I've been on the receiving end of sample requests for over 20 years.
And I can tell you, there's a right way and a wrong way to ask for a custom woven fabric sample.
The wrong way? An email that says: "I need a sample of a cotton fabric. Can you send?"
The right way? A detailed request that tells me exactly what you need, what you're trying to achieve, and how I can help you get there.
Let me tell you about a client who got it right.
In 2023, a London-based menswear designer emailed us. She didn't just ask for a sample. She sent a tech pack with a weaving diagram, a Pantone color reference, a target weight, a required width, and a photo of a fabric with a similar handfeel. She also told us her timeline, her minimum order quantity, and her quality expectations.
We developed the sample in 10 days. She approved it. We produced 15,000 meters. The collection launched on time. She's been ordering from us ever since.
That's what a perfect sample request looks like.
Today, I'm going to walk you through exactly how to request a custom woven fabric sample. I'll tell you what information to include, what mistakes to avoid, and how to work with your supplier to get the sample you need—fast.
What Information Do I Need to Provide Before Requesting a Sample?
Let me be direct with you.
The more information you give me upfront, the faster I can get you a sample that's actually useful.
If you send me a vague request, I have to email back asking questions. You answer. I ask more questions. You answer again. Days go by. The sample gets delayed.
Here's what I need to know before I can develop a custom woven sample.
What Are the Non-Negotiable Specifications I Must Define?
Let me give you the checklist I use with every client.
1. Fiber Content
What is the fabric made from? 100% cotton? Cotton-polyester blend? Wool? Linen? Nylon?
Be specific. "Cotton" is not specific enough. 100% combed cotton is different from 100% carded cotton. 80/20 cotton-polyester is different from 60/40.
If you don't know the exact blend, tell me what properties you need. Breathability? Durability? Stretch? Wrinkle resistance? I can recommend a blend based on your requirements.
2. Yarn Count
This is one of the most important specifications and one that most non-technical buyers don't know how to define.
Yarn count tells us how thick or thin the yarns are.
For cotton, we use the Ne (English Cotton Count) system. A higher number means a finer yarn. 20s is a thicker yarn, good for canvas and workwear. 60s is a fine yarn, good for shirting and lightweight fabrics.
For polyester and nylon, we use denier. 20 denier is very fine, like in lightweight rainwear. 200 denier is heavier, like in luggage and outdoor gear.
If you're not sure what yarn count you need, tell me what weight you want and what the fabric will be used for. I can recommend the right yarn count.
3. Weave Structure
Woven fabrics have different structures.
- Plain weave is the simplest. Warp and weft yarns cross over and under each other. It's stable and crisp.
- Twill weave creates a diagonal pattern. It's more flexible and drapes better than plain weave. Denim is a twill.
- Satin weave has long floats that create a smooth, lustrous surface. It's beautiful but less durable.
If you have a specific weave in mind, describe it. If you're not sure, tell me what you want the fabric to look and feel like. I can suggest the right weave.
4. Weight
Weight is measured in grams per square meter (GSM) or ounces per square yard (oz/yd²).
A lightweight shirting fabric might be 120-150 GSM. A mid-weight chino fabric might be 200-250 GSM. A heavy canvas might be 350-400 GSM or more.
If you don't have a specific weight, tell me what the fabric will be used for. A shirt needs a different weight than a jacket. A summer fabric is lighter than a winter fabric.
5. Width
Finished fabric width is usually measured after finishing. Standard widths are 140-150 cm (55-60 inches) for most apparel fabrics. Some technical fabrics are narrower. Some home textiles are wider.
If you're manufacturing garments, tell me your pattern width. I can suggest the most efficient width to minimize waste.
6. Color
This is where a lot of sample requests go wrong.
"I need a navy blue sample" is not enough. Navy blue can mean anything.
Provide a Pantone reference. If you don't have a Pantone number, send a physical color standard. A piece of paper, a paint chip, a photo of a garment—anything that shows me the exact color you want.
If you're matching to an existing product, send me that product. I can use our spectrophotometer to analyze the color and match it precisely.
In 2024, a client from Australia sent us a dried flower as their color standard. They wanted a cotton-linen fabric in the exact shade of that dried flower. We scanned the flower with our spectrophotometer, developed a lab dip, and matched it perfectly. Their collection was beautiful.
What's the Difference Between a Lab Dip and a Strike-Off?
This is a common point of confusion.
Let me explain.
A lab dip is a small piece of fabric—usually about 20cm x 30cm—that shows the color. The lab dip is made in our lab on a sample machine. It's not the final fabric construction. It's just showing you the color.
We send lab dips first. You approve the color. Then we move to the strike-off.
A strike-off is a small piece of fabric—usually about 50cm x 50cm—that shows the actual fabric construction with the approved color. The strike-off is made on production machines or sample looms. It shows you the weave, the texture, the handfeel, and the color together.
Never approve a fabric based only on a lab dip. You need to see a strike-off. The lab dip tells you about color. The strike-off tells you about everything else.
I had a client in 2022 who approved a lab dip without seeing a strike-off. They went straight to bulk production. When the fabric arrived, the weave was tighter than they expected. The handfeel was different. They had to reject the entire order.
That was a $30,000 mistake. All because they skipped the strike-off step.
How Should I Communicate My Quality Requirements?
Quality is not a feeling. It's a set of measurable standards.
If you tell me "I want high quality," I don't know what that means. Your high quality might be different from my high quality.
Here's how to communicate quality requirements clearly.
What Test Standards Should I Specify?
For woven fabrics, here are the key tests you should consider specifying.
1. Shrinkage
Specify the maximum shrinkage you'll accept after three home laundries.
For most woven apparel, 2-3% is acceptable. For tailored garments, you might want 2% or less.
Reference test method: AATCC 135 (US) or ISO 6330 (international).
2. Colorfastness
Specify colorfastness to washing, light, and rubbing.
For washing, a rating of 4-5 out of 5 is standard for most apparel.
For light, the standard is a Blue Wool rating. For outdoor fabrics, you might want a rating of 5 or higher.
For rubbing (crocking), a rating of 4 or higher is standard for dark colors.
Reference test methods: AATCC 61 (washing), AATCC 16 (light), AATCC 8 (dry rubbing), AATCC 116 (wet rubbing).
3. Tensile Strength and Tear Strength
These measure how strong the fabric is.
For a standard shirting fabric, you might not need high strength. For outdoor gear or workwear, you'll want specific strength targets.
Reference test methods: ASTM D5034 (tensile), ASTM D1424 (tear).
4. Pilling Resistance
This measures whether the fabric will form little balls of fuzz on the surface.
For woven fabrics, a rating of 4 or higher is good. For fabrics with synthetic fibers, pilling can be more of an issue.
Reference test method: ASTM D3512 (random tumble), ASTM D4970 (Martindale).
In 2023, a US-based workwear brand came to us with a very specific test matrix. They wanted 2% maximum shrinkage, 4.5 colorfastness to light, and a minimum tear strength of 15 pounds. They provided the test methods and the acceptable ranges.
We developed the fabric. We tested it. We provided the reports. They approved. The bulk production passed the same tests.
That's how it should work. Clear standards, measurable results, no surprises.
Should I Ask for a Quality Control Plan?
Yes. Absolutely.
Before you approve a sample, ask your supplier how they will ensure the bulk fabric matches the sample.
At Shanghai Fumao, we have a standard QC plan for every order:
- Incoming yarn testing — we test every batch of yarn for strength, evenness, and color
- In-process inspection — we check the fabric at the loom, after dyeing, and after finishing
- Final inspection — we inspect every roll using AQL (Acceptable Quality Limit) standards, typically AQL 2.5 for apparel fabrics
- Roll tracking — every roll gets a QR code linking to its test report
Ask your supplier what their QC process is. Ask to see the test reports. Ask what AQL they use.
A good supplier will have answers to these questions. A bad supplier will avoid them.
How Do I Manage the Sample Timeline?
Time is money. I know that.
And sample development takes time. If you don't plan for it, it will eat into your production timeline.
What's a Realistic Timeline for Custom Woven Fabric Samples?
Let me give you a realistic timeline based on our operations.
Lab Dip Development: 5-7 days
We need to source the yarn, prepare the dye recipe, and run the lab dip. If you provide a Pantone reference or physical standard, this is straightforward. If you're trying to match a complex color or a specific texture, it may take longer.
Lab Dip Approval: 2-5 days
You need time to review the lab dip. If you're working with a remote team, factor in shipping time. We can send photos and digital color measurements, but physical evaluation is always better.
Strike-Off Development: 7-10 days
Once the color is approved, we set up the sample loom or production machine. We run the strike-off. We finish it—desizing, scouring, dyeing, and finishing.
Strike-Off Approval: 2-5 days
You review the strike-off. Check the weave, the handfeel, the color, the weight. If it's perfect, we move to bulk. If it needs adjustments, we go back and do another strike-off.
Total Timeline: 3-4 weeks for a standard development, 4-6 weeks for complex fabrics
This is the time from your initial request to an approved strike-off ready for bulk production.
In 2024, we developed a complex jacquard fabric for a European luxury brand. The pattern had 12 colors and required special loom setup. The lab dip took 10 days. The strike-off took 14 days. The client requested one revision. Total timeline was 6 weeks.
They planned for it. Their production schedule accounted for it. Everything went smoothly.
How Do I Plan for Chinese Holidays?
This is critical if you're sourcing from China.
Chinese New Year (CNY) is the biggest disruption. Factories shut down for 3-4 weeks, usually in January or February.
If you need a sample developed during CNY, it's not happening. Plan around it.
Golden Week is the first week of October. Most factories shut down for 7 days.
May Day is the first week of May. Another 7-day shutdown.
I tell all my clients: if you need samples by a certain date, count backwards from that date and add buffer. For CNY, add at least 3 weeks to your timeline.
In 2023, a New York-based brand needed samples by mid-February for a summer collection. They sent their request in early December. We developed the samples in January, before the CNY shutdown. They received the samples in early February. Perfect timing.
A competitor who requested samples in late January was still waiting in March.
What Mistakes Should I Avoid When Requesting Samples?
I've seen every mistake in the book. Let me save you from the most common ones.
What Are the Top 5 Sample Request Mistakes?
1. Not Providing a Physical Color Standard
Digital colors are not reliable. What you see on your screen is not what I see on my screen. Provide a Pantone number or send a physical standard.
A US-based brand learned this in 2022. They sent us a photo of a fabric they liked. We matched the color from the photo. They approved the lab dip from a photo we sent. When the strike-off arrived, the color was wrong. The photo had been taken under different lighting. We wasted three weeks and $500 in shipping fees.
2. Approving a Sample Without Testing It
A sample that looks good is not the same as a sample that performs.
I had a client who approved a sample based on appearance. They went to bulk production. The fabric shrank 6% in production because the sample hadn't been tested. They had to re-cut their entire order.
Always test your samples. Wash them. Dry them. See what happens.
3. Changing Specifications After Sample Approval
This is the most frustrating mistake for a supplier.
You approve a sample. We order yarn. We set up machines. Then you decide you want a different weight. Or a different color. Or a different weave.
Every change after sample approval adds cost and time. The yarn we ordered is now useless. The machine setup needs to be redone.
If you're not sure about something, ask for more samples. Don't approve something you're not certain about.
4. Not Communicating Your End Use
Tell me what the fabric is for.
A shirt fabric needs different properties than a jacket fabric. A summer fabric needs different properties than a winter fabric. A lining fabric needs different properties than an outer shell fabric.
If you tell me the end use, I can recommend the right construction, the right finishing, the right tests.
5. Waiting Until the Last Minute
Sample development takes time. If you need fabric for a collection launching in six months, start the sample process now. Don't wait.
I've had clients who needed samples in two weeks for a trade show. We can rush samples sometimes. But rush costs money. And rushed samples are more likely to have issues.
Plan ahead. Give yourself time. Your supplier will appreciate it, and your sample will be better.
