Custom apparel can include:
- Branded T-shirts
- Corporate uniforms
- Sports jerseys
- Promotional clothing
- Event T-shirts
- Hoodies
- Polos
- Teamwear
- Gym wear
- Staff uniforms
- Merchandise
For these products, fabric selection is one of the most important decisions.
A custom design can look excellent on screen but perform poorly if the wrong fabric is selected.
For example, the garment may:
- Feel uncomfortable
- Print badly
- Shrink
- Lose shape
- Become transparent
- Pill quickly
- Fade after washing
Polyester is widely used for custom apparel because it offers a strong balance of:
- Durability
- Quick drying
- Colour retention
- Printing compatibility
- Easy care
- Wide GSM options
- Bulk availability
However, not every polyester fabric is suitable for every custom apparel project.
Buyers need to consider the garment type, printing method, GSM, stretch, hand feel, durability, and end use before placing a bulk order.
This guide explains what buyers should check when choosing polyester fabric for custom apparel.
Why Polyester Is Popular for Custom Apparel
Polyester works well for custom apparel because it can be manufactured in many different structures.
It can be made:
- Lightweight
- Heavy
- Stretchable
- Smooth
- Brushed
- Mesh
- Matte
- Textured
This gives buyers flexibility for different products.
For example:
| Custom Apparel Type | Suitable Polyester Option |
|---|---|
| Sports Jersey | Mesh / Interlock |
| Promotional T-Shirt | Single Jersey / Interlock |
| Polo Shirt | Piqué |
| Leggings | Polyester-Lycra |
| Hoodie | Fleece |
| Track Pants | Double Knit / Interlock |
| Teamwear | Sublimation Polyester |
1. Start With the End Use
Before choosing fabric, ask:
Where will the garment be used?
This is the most important question.
Different applications need different performance.
For example:
Corporate T-Shirts
Priorities may include:
- Clean appearance
- Comfort
- Colour consistency
- Embroidery compatibility
Sportswear
Priorities may include:
- Quick drying
- Breathability
- Lightweight construction
- Moisture management
Event T-Shirts
Priorities may include:
- Competitive cost
- Good printing
- Bulk availability
Hoodies
Priorities may include:
- Warmth
- Softness
- Structure
Do not choose fabric only because it is cheap or available.
2. Check the Fabric Composition
Always confirm the exact composition.
Common options include:
- 100% Polyester
- Polyester-Lycra
- Polyester-Cotton
- Polyester-Viscose
Each behaves differently.
100% Polyester
Suitable for:
- Sportswear
- Promotional T-shirts
- Sublimation jerseys
- Uniforms
Advantages include:
- Quick drying
- Colour retention
- Easy care
Polyester-Lycra
Suitable for:
- Leggings
- Gym wear
- Fitted tops
- Dancewear
Advantages include:
- Stretch
- Recovery
- Flexibility
Polyester-Cotton
Suitable for:
- Corporate T-shirts
- Uniforms
- Casualwear
This blend can provide:

3. Choose the Right GSM
GSM means:
Grams per Square Metre
It measures fabric weight.
GSM affects:
- Feel
- Coverage
- Structure
- Comfort
A general guide:
| Garment | Suggested GSM |
|---|---|
| Lightweight Sports T-Shirt | 120–160 GSM |
| Promotional T-Shirt | 140–180 GSM |
| Polo Shirt | 170–220 GSM |
| Leggings | 180–240 GSM |
| Track Pants | 200–260 GSM |
| Hoodie | 240–320+ GSM |
These are general ranges.
The correct GSM depends on fabric construction.
Higher GSM Does Not Always Mean Better Quality
A common buyer mistake is assuming:
Higher GSM = Higher quality
That is not always true.
A well-made 150 GSM sports fabric may perform better than a poor-quality 220 GSM fabric.
Quality depends on:
- Yarn
- Construction
- Finish
- Stretch
- Recovery
- Dyeing
not just weight.
4. Check Fabric Structure
Polyester can be knitted or woven into many structures.
Common custom apparel structures include:
- Single jersey
- Interlock
- Piqué
- Mesh
- Double knit
- Fleece
Each gives different performance.
Single Jersey
Good for:
- T-shirts
- Promotional clothing
Usually:
- Lightweight
- Flexible
- Comfortable
Interlock
Good for:
- Sportswear
- Uniforms
- Co-ord sets
Usually:
- Smooth
- Stable
- More structured
Piqué
Commonly used for:
- Polo shirts
It provides:
- Textured appearance
- Good structure
Mesh
Best for:
- Sportswear
- Training wear
It provides:
- Airflow
- Lightweight feel
Double Knit
Suitable for:
- Track pants
- Jackets
- Structured sportswear
It provides:
- Stability
- Durability
Fleece
Best for:
- Hoodies
- Sweatshirts
It provides:
- Warmth
- Softness
5. Select Fabric Based on Printing Method
Custom apparel usually includes branding.
The fabric must be compatible with the planned decoration method.
Common methods include:
- Sublimation
- DTF
- Screen printing
- Heat transfer
- Embroidery
Sublimation
Polyester is ideal for sublimation.
It is especially suitable for:
- White
- Light-coloured polyester
Sublimation provides:
- Bright colours
- Detailed graphics
- Lightweight print feel
It is commonly used for:
- Sports jerseys
- Teamwear
- Event T-shirts
DTF Printing
DTF can be used on polyester.
It works well for:
- Small quantities
- Multi-colour logos
- Dark garments
However, large DTF prints can reduce:
- Breathability
- Stretch
This should be considered for sportswear.
Screen Printing
Screen printing is suitable for:
- Bulk orders
- Simple logos
- Bold designs
The ink and curing temperature must be suitable for polyester.
Dye Migration
One important issue with polyester printing is:
Dye migration
This happens when polyester dye moves into the printed area during heat exposure.
It can cause:
- Colour contamination
- Poor print appearance
This is especially common on:
- Dark polyester
Use:
- Low-temperature inks
- Migration-resistant systems
where necessary.
Heat Transfer
Heat transfer is suitable for:
- Names
- Numbers
- Logos
But high temperature can affect polyester.
Always test:
- Heat
- Pressure
- Time
before bulk production.
Embroidery
Embroidery works well on:
- Polos
- Jackets
- Hoodies
- Uniforms
The fabric should have enough stability.
Very lightweight fabric may:
- Pucker
- Distort
under heavy embroidery.
6. Check Colour Requirements
Custom apparel often needs exact brand colours.
Buyers should check:
- Shade consistency
- Lot-to-lot variation
- Colour fastness
This is especially important for:
- Uniform programs
- Franchise clothing
- Corporate branding
Pantone Matching
If a brand requires a specific colour, provide:
- Pantone reference
- Physical approved swatch
Do not rely only on:
- Phone screens
- Laptop colours
Screens display colours differently.
7. Check Colour Fastness
Custom garments are usually washed repeatedly.
Check colour fastness to:
- Washing
- Rubbing
- Light
Poor colour fastness may cause:
- Fading
- Colour transfer
8. Check Stretch Requirements
Stretch is important for:
- Activewear
- Leggings
- Fitted tops
Polyester-Lycra may provide:
- Two-way stretch
- Four-way stretch
Choose according to garment movement.
Four-Way Stretch
Four-way stretch works well for:
- Leggings
- Gym wear
- Dancewear
because the fabric stretches in both:
- Length
- Width
9. Recovery Is as Important as Stretch
A fabric can stretch well but recover poorly.
Poor recovery can cause:
- Bagging
- Sagging
- Loose knees
Always test:
- Stretch percentage
- Recovery
10. Check Hand Feel
The fabric should match the expected customer experience.
For example:
Premium Corporate Polo
May require:
- Smooth
- Soft
- Structured feel
Sports Jersey
May require:
- Lightweight
- Dry-touch feel
Hoodie
May require:
- Soft
- Brushed feel
Hand feel should match product positioning.
11. Check Breathability
Breathability matters for:
- Sportswear
- Staff uniforms
- Outdoor events
Airflow depends on:
- Fabric structure
- GSM
- Density
Mesh structures usually provide more airflow than dense knits.
12. Check Moisture Management
Performance apparel may require:
- Moisture wicking
- Quick drying
Not every polyester fabric automatically has strong moisture-management performance.
Ask whether the fabric has:
- Wicking finish
- Quick-dry finish
and whether it has been tested.
13. Check Shrinkage
Polyester usually has good dimensional stability.
Still, buyers should test:
- Length shrinkage
- Width shrinkage
before bulk production.
Even small shrinkage can affect:
- Sizing
- Print position
- Garment fit
14. Check Pilling
Pilling can make custom garments look worn quickly.
This is especially important for:
- Uniforms
- Hoodies
- Track pants
Check pilling resistance before approving the fabric.
15. Check Abrasion Resistance
Garments such as:
- Workwear
- Sportswear
- School uniforms
may experience heavy friction.
The fabric should resist:
- Surface wear
- Fibre breakage
16. Check Opacity
Opacity matters for:
- White T-shirts
- Leggings
- Light-coloured uniforms
Test the fabric:
- Under stretch
- In bright light
A fabric that looks fine as a swatch may become transparent when worn.
17. Check Fabric Width or DIA
Fabric width affects:
- Cutting efficiency
- Consumption
- Garment cost
For tubular knitted fabrics, buyers may refer to:
DIA
Make sure the actual usable width suits the garment pattern.
18. Fabric Width Affects Cost
Wider fabric can sometimes reduce:
- Marker waste
- Consumption
But this depends on:
- Garment pattern
- Size range
Ask the cutting team before finalizing.
19. Check Roll Weight and Quantity
For bulk custom apparel, confirm:
- Roll weight
- Total kilograms
- Approximate yield
Fabric quantity should include:
- Cutting wastage
- Defects
- Sampling
- Replacements
20. Calculate Fabric Consumption
Before ordering bulk fabric, calculate:
Average fabric consumption per garment
Consumption depends on:
- Size
- GSM
- Width
- Pattern
- Garment type
Poor consumption planning can create:
- Shortage
- Excess inventory
21. Check Lot Consistency
Do not assume every roll will be identical.
Check:
- Shade
- GSM
- Width
- Hand feel
across the bulk lot.
22. Shade Variation Can Affect Custom Apparel
If different garment parts use different shade rolls, the final garment may look mismatched.
This is called:
Shade variation
Use shade grouping during cutting if necessary.
23. Check Fabric Defects
Common defects include:
- Holes
- Streaks
- Knitting lines
- Oil marks
- Dye marks
- Uneven width
Bulk rolls should be inspected before cutting.
24. Sample Before Bulk Production
Never approve custom apparel fabric based only on a swatch.
Create a complete garment sample.
The sample should include:
- Actual fabric
- Actual print
- Actual embroidery
- Actual trims
25. Test the Finished Garment
The finished sample should be checked for:
- Fit
- Comfort
- Print quality
- Stretch
- Appearance
This is called a practical wear test.
26. Wash-Test the Sample
Wash the garment before bulk approval.
Check:
- Shrinkage
- Fading
- Pilling
- Print durability
- Shape retention
This is one of the most important steps.
27. Check Print After Washing
Printing should be checked for:
- Cracking
- Peeling
- Fading
- Dye migration
Do not test only the fresh print.
28. Consider Customer Usage
Custom apparel should be designed around the actual user.
Ask:
- Will it be used indoors?
- Outdoors?
- During sports?
- For eight-hour shifts?
- For one-day events?
These answers change the fabric requirement.
29. Consider Climate
Climate matters.
For hot environments, prioritize:
- Lightweight GSM
- Breathable structures
- Quick drying
For cooler environments:
- Fleece
- Brushed polyester
may be better.
30. Consider Order Quantity
Fabric choice should also match order size.
For small custom orders:
- Ready-stock fabrics may be practical
For large orders:
- Custom dyeing
- Custom finishes
may become possible.
31. Check Minimum Order Quantity
Ask the supplier about:
- MOQ
- Colour MOQ
- Custom dyeing MOQ
This is especially important for startups.
32. Ask About Repeat Availability
For uniforms or brand merchandise, repeat orders may be required.
Ask:
- Will this fabric remain available?
- Can the same shade be repeated?
This helps maintain consistency.
33. Check Lead Time
Custom apparel production involves:
- Fabric
- Dyeing
- Printing
- Cutting
- Stitching
- Finishing
Confirm the lead time before promising delivery to customers.
34. Consider Total Cost, Not Only Fabric Price
The cheapest fabric is not always the cheapest garment.
Poor-quality fabric may cause:
- Print rejection
- Cutting waste
- Rework
- Customer returns
Consider total garment cost.
35. What Buyers Should Ask the Fabric Supplier
Useful questions include:
- What is the composition?
- What is the GSM?
- What is the DIA or width?
- Is it suitable for sublimation?
- Is it quick drying?
- Does it contain Lycra?
- What is the MOQ?
- Is bulk shade repeatable?
- Can I get a sample?
