Step-by-Step T-Shirt Manufacturing Process

Step 1 – Fabric Selection

Most T-shirts use single-jersey knit fabrics made from 100% cotton, cotton-polyester blends, organic cotton, or performance blends. If you are comparing fabric options, this guide to cotton vs polyester T-shirts can help you understand the differences in comfort, durability, shrinkage, and cost. Fabric weight is usually measured in GSM, which means grams per square meter.

For mainstream T-shirts, fabric weight often ranges from around 140–220 GSM. If you are unsure which weight is right for your brand, our T-shirt GSM guide explains how different fabric weights affect handfeel, structure, seasonality, and cost. Lightweight fabrics are common for promotional tees or summer basics, while 180–220 GSM fabrics are often preferred by brands that want a more premium, structured feel.

Softer handfeel usually comes from combed cotton, ring-spun yarn, or special finishing. Blends can improve durability, reduce shrinkage, and support faster drying.

Factory note from Easson Apparel:
For most custom T-shirt projects, we usually recommend 180–220 GSM cotton or cotton-blend jersey if the brand wants a more premium handfeel and better structure. Lightweight 140–160 GSM fabric can work for promotional tees, but it may feel too thin for premium streetwear or private-label collections.

Startup note: Fabric is usually one of the biggest cost drivers in T-shirt production. Each colorway can trigger its own minimums at the fabric mill or dyehouse, so adding too many colors may increase MOQ, unit cost, and production time.

Step 2 – Fabric Knitting

Cotton yarn or blended yarn becomes fabric through circular knitting machines. For a simple technical explanation of circular knitting machines, CottonWorks has a useful overview of knit machinery¹. Single jersey is the most common fabric construction for T-shirts because it is soft, flexible, breathable, and efficient for bulk production.

Machine gauge, stitch length, yarn count, and yarn tension all affect GSM, stretch, drape, and fabric stability. Some factories produce tubular fabric, while others use open-width fabric depending on the garment style and production method.

Checkpoint: During fabric production, small swatches should be weighed to confirm GSM against the approved specification. If the fabric weight drifts too much, the factory may need to adjust stitch length or machine settings.

---

Step 3 – Fabric Dyeing and Finishing

The dyeing method depends on the fiber content. Cotton is usually dyed with reactive dyes, while polyester uses disperse dyes at higher temperature and pressure. For cotton-polyester blends, dyeing may require different dye systems to achieve the correct shade and fastness.

After dyeing, the fabric may go through washing, softening, drying, compacting, and finishing. These steps affect handfeel, shrinkage, width, color stability, and appearance.

Checkpoint: Before bulk dyeing, the buyer should approve lab dips under standard lighting such as D65. The factory should also run basic wash and rub tests to check colorfastness before moving into bulk production. For buyers who want to understand color transfer testing, AATCC explains the purpose of colorfastness to crocking² testing for textiles.

---

Step 4 – Pattern Making and Grading

Pattern makers translate the design and fit requirements into production patterns. These patterns define the shape of each garment part, including the front body, back body, sleeves, collar, neck rib, and any special panels.

After the base size is approved, the pattern is graded into other sizes such as XS, S, M, L, XL, and XXL. CAD systems such as Gerber or Lectra can help maintain measurement accuracy and improve cutting efficiency.

Checkpoint: Before cutting bulk fabric, confirm seam allowances, notches, grainlines, label positions, collar width, sleeve length, body length, and size grading. A pre-production sample should be approved before bulk production starts.

---

Step 5 – Fabric Relaxation and Cutting

Before cutting, knitted fabric should usually be relaxed. This means the fabric is laid out and allowed to rest before cutting. For cotton jersey and stretch fabrics, relaxation helps reduce shrinkage, twisting, and shape distortion after sewing or washing. CottonWorks also explains how shrinkage and skewing³ can affect cotton fabrics and finished garments.

After relaxation, the fabric is spread in layers on the cutting table. The marker, which is the layout of all pattern pieces, is placed on top. The cutting team then cuts the fabric using straight knives, round knives, or automated cutting machines.

Good marker planning improves fabric yield and helps reduce cost. Poor marker planning can waste fabric and increase the final unit price.

Checkpoint: Inspect fabric before cutting and avoid placing defects in visible areas. For knitted fabrics, relaxation is especially important because cutting too early can cause twisting, shrinkage, or measurement changes later.

---

Step 6 – Sewing and Assembly

After cutting, the panels move to the sewing line. Operators join the garment parts together using different machines depending on the seam type.

Common machines used in T-shirt sewing include:

Machine Type	Common Use
Overlock machine	Side seams, shoulder seams, sleeve joining
Coverstitch machine	Bottom hem, sleeve hem, neckline finishing
Lockstitch machine	Labels, reinforcement, topstitching
Rib attaching machine	Neck rib or collar attachment

Needle type, thread tension, seam allowance, and differential feed all affect final quality. For knitted fabrics, a ballpoint needle is often used to avoid damaging the fabric loops.

Checkpoint: In-line QC should check shoulders, collar shape, sleeve joining, side seams, hem width, and measurement consistency. Catching problems during sewing is much cheaper than repairing finished garments after final inspection.

---

Step 7 – Printing or Embroidery

After sewing, some T-shirts go through printing or embroidery. In some production workflows, printing may happen before sewing, especially when the artwork placement is easier to control on flat panels.

Common T-shirt decoration methods include:

Method	Best For	Notes
Screen Printing	Medium to large orders, simple color designs	Low unit cost after setup; durable when cured correctly
DTG Printing	Small runs, complex artwork, many colors	Good for small batches but less efficient for large orders
Heat Transfer	Names, numbers, small batches, special effects	Flexible but quality depends on transfer material
Embroidery	Logos, premium branding details	More structured and premium, but heavier and more expensive
Puff / Flock / Special Printing	Streetwear and fashion designs	Requires testing for handfeel and durability

If you are comparing DTG and screen printing for your first T-shirt order, this DTG vs screen printing guide⁴ gives a simple explanation of how design complexity and order quantity affect the best choice.

For plastisol screen prints, the ink must be cured properly. If the curing temperature or time is wrong, the print may crack, peel, or fail after washing.

Checkpoint: Approve strike-offs or test prints before bulk production. Confirm artwork size, Pantone color, print placement, handfeel, and wash durability.

Factory note from Easson Apparel:
For startup brands, printing cost can increase quickly if there are too many artwork placements or too many colors. A simple one-position screen print is much easier to control than several large prints across the chest, back, sleeves, and hem. If the first order budget is limited, simplifying the print design can help keep the unit cost reasonable.

If you already have artwork, send us a PNG with transparent background, AI file, PDF, or vector file. We can help check whether your design is more suitable for screen printing, embroidery, heat transfer, or another method.

---

Step 8 – Quality Inspection

Quality inspection should happen at different stages, not only at the end. A good T-shirt factory usually checks quality during fabric inspection, cutting, sewing, printing, finishing, and final packing.

Most brands use AQL inspection before shipment. A common apparel inspection standard is:

• Critical defects: 0.0
• Major defects: 2.5
• Minor defects: 4.0
• Inspection level: General Level II

Inspectors usually check:

• Measurements
• Fabric defects
• Stains or oil marks
• Seam quality
• Collar shape
• Sleeve and hem symmetry
• Print placement
• Print curing
• Embroidery quality
• Label position
• Size labels
• Packing accuracy
• Carton marks

Checkpoint: Final AQL inspection is important, but it should not replace in-line quality control. If defects are only discovered at the final stage, rework becomes slower and more expensive.

---

Step 9 – Packaging and Shipping

After final trimming, pressing, and inspection, T-shirts are folded and packed according to the buyer’s requirements. Common packaging options include individual polybags, size stickers, barcode labels, hang tags, tissue paper, inner cartons, and master cartons.

For export orders, the packing details should be confirmed before bulk production ends. This includes carton size, carton weight, shipping marks, SKU labels, and destination requirements.

If humidity is a concern, desiccants may be added to reduce moisture risk during shipping.

Shipping method depends on budget and launch timeline:

Shipping Method	Best For	Notes
Air freight	Urgent orders, small shipments	Faster but more expensive
Sea freight	Larger bulk orders	Lower cost but longer transit time
Express courier	Samples or small urgent packages	Convenient but not ideal for large-volume goods

Checkpoint: Confirm packing instructions early. Last-minute packaging changes can delay shipment, especially if barcode labels, hang tags, or special cartons are required.

---

How Long Does It Take to Manufacture T-Shirts?

The timeline depends on fabric availability, order quantity, colorways, decoration method, sample revisions, approval speed, and factory capacity.

For most custom T-shirt projects, the typical timeline is:

Stage	Typical Timeline
Basic T-shirt sample	8–12 days after details are confirmed
Complex sample	12–20 days if custom fabric, special fit, printing, embroidery, washing, or multiple revisions are needed
Bulk production	25–35 days after sample approval and deposit
Custom-dyed fabric or peak season orders	35–50+ days depending on dyeing, trims, approvals, and capacity
Shipping	Depends on air, sea, express, and destination country

Several factors can extend the production timeline:

• Non-stock fabric
• Custom dyeing
• Multiple colorways
• Complex print or embroidery
• Slow lab dip approval
• Slow artwork confirmation
• Multiple sample revisions
• Special packaging requirements
• Peak-season factory capacity

Factory note from Easson Apparel:
One of the easiest ways to keep a T-shirt order on schedule is to confirm fabric, size chart, artwork, color, and packaging before sampling starts. If these details change after the pre-production sample is approved, the bulk timeline may need to be adjusted.

What Buyers Need to Prepare Before T-Shirt Production

Before contacting a T-shirt manufacturer, it helps to prepare the key production details. You do not need to have everything perfect, but the more complete your information is, the faster the factory can quote, sample, and plan production.

Here is a practical checklist:

Item	Why It Matters
Design reference	Helps the factory understand the style direction
Tech pack	Includes measurements, construction, trims, and details
Size chart	Reduces fit misunderstanding
Fabric composition	Helps determine cost, handfeel, and shrinkage
GSM requirement	Affects thickness, structure, and price
Color requirement	Determines stock fabric or custom dyeing
Artwork file	Needed for printing or embroidery
Logo placement	Affects production method and cost
Quantity per color and size	Affects MOQ and unit price
Packaging requirement	Affects lead time and final cost
Target market	Helps the factory understand fit and quality expectations

For startup brands, it is normal to begin with reference photos and rough ideas. A good factory can help turn those ideas into more complete production details.

Common Problems During T-Shirt Manufacturing

Even simple T-shirts can have quality problems if the process is not controlled properly. Common issues include:

1. Fabric Shrinkage

Cotton fabrics may shrink after washing if they are not properly finished or tested. This can affect body length, sleeve length, chest width, and overall fit.

2. Twisting or Spirality

Knitted fabric can twist after washing if fabric relaxation, knitting tension, or finishing is not controlled well.

3. Neckline Deformation

A weak or poorly sewn collar can stretch, wave, or lose shape after washing. Rib quality and sewing tension are both important.

4. Poor Print Durability

If screen printing ink is not cured properly, the print may crack or peel. Test prints and wash tests help reduce this risk.

5. Color Difference

Lab dip approval does not always guarantee perfect bulk shade if dyeing is not controlled well. Buyers should allow reasonable tolerance and approve colors under standard lighting.

6. Measurement Inconsistency

Different operators, fabric behavior, and sewing tension can affect final measurements. In-line QC and final measurement checks are necessary.

How to Reduce T-Shirt Manufacturing Cost Without Lowering Quality

For new clothing brands, reducing cost does not always mean choosing the cheapest fabric. A better approach is to simplify the first production run and reduce unnecessary complexity.

Here are practical ways to control cost:

Cost-Saving Method	Why It Helps
Use available fabric colors	Reduces dyeing cost and lead time
Limit the number of colorways	Helps meet MOQ more easily
Start with fewer artwork placements	Reduces printing setup cost
Use one main fabric across styles	Improves fabric efficiency
Keep packaging simple at first	Reduces accessory and packing cost
Confirm specs before sampling	Avoids repeated sample revisions
Increase quantity gradually	Helps reduce unit cost over time

For example, a startup brand may begin with one T-shirt style, two colors, and one main logo placement. After testing the market, the brand can expand into more colors, heavier fabrics, special washes, or more complex decoration.

If you are unsure how to balance fabric quality, MOQ, and unit price, you can send us your target budget and order quantity. We can suggest a more production-friendly way to develop your first T-shirt order.

FAQ

How long does it take to manufacture custom T-shirts?

For most custom T-shirt projects, sampling usually takes 8–12 days after fabric, artwork, size spec, and construction details are confirmed.

If the style involves custom-dyed fabric, special fit, complex printing, embroidery, washing, or multiple revisions, sampling may take 12–20 days.

Bulk production usually takes around 25–35 days after sample approval and deposit. Orders with custom fabric dyeing, many colorways, special trims, or peak-season capacity pressure may require 35–50+ days.

---

What is the minimum order quantity for custom T-shirts?

MOQ varies depending on the manufacturer, fabric, color, and customization level. Many clothing manufacturers set a minimum order quantity of around 100–300 pieces per style for custom T-shirts.

Some factories may support smaller startup orders if stock fabrics are used and the design is simple. However, very small runs usually have a higher unit price because fabric sourcing, pattern making, sample development, printing setup, and production management still require time and labor.

Using available fabric colors, reducing the number of colorways, and simplifying printing can help lower the MOQ pressure.

---

What fabric is best for high-quality T-shirts?

The most common fabric for high-quality T-shirts is 100% cotton, especially combed or ring-spun cotton, because it feels soft, breathable, and comfortable.

Cotton-polyester blends are also popular because they can improve durability, reduce shrinkage, and dry faster. For premium private-label T-shirts, many brands choose 180–220 GSM cotton or cotton-blend jersey because it provides a thicker and more structured feel compared with lightweight fabrics.

The best fabric depends on the target customer, retail price, season, and brand positioning.

---

What factors affect the cost of manufacturing T-shirts?

Several factors influence the final cost of T-shirt production, including:

• Fabric composition
• Fabric GSM
• Order quantity
• Number of colorways
• Printing or embroidery method
• Artwork size and placement
• Label and packaging requirements
• Sample complexity
• Quality standard
• Shipping method

For example, heavyweight cotton fabric, custom dyeing, embroidery, multiple print placements, and premium packaging will increase production cost. Larger orders usually reduce the unit price because the factory can optimize fabric purchasing, cutting, printing setup, and sewing line efficiency.

---

What printing methods are commonly used for T-shirts?

The most common T-shirt printing methods are screen printing, DTG printing, heat transfer, and embroidery.

Screen printing is cost-effective for larger orders and simple designs with limited colors. DTG printing works well for small batches and complex artwork with many colors. Heat transfer is flexible for smaller runs or special effects. Embroidery is often used for logos and premium branding details.

The right method depends on artwork complexity, order quantity, fabric type, handfeel requirement, and target price.

---

Can startup brands manufacture T-shirts with low MOQ?

Yes, some factories support startup brands with lower MOQs, especially when the order uses stock fabric, simple colors, and standard construction.

However, low MOQ does not always mean low unit cost. A 50-piece or 100-piece order may still require pattern making, sample development, artwork checking, printing setup, cutting, sewing, QC, and packing. This is why smaller orders usually have higher unit prices than larger bulk orders.

For startups, a practical approach is to begin with fewer styles, fewer colors, and one or two strong designs. This helps reduce cost and makes the first order easier to control.

---

Conclusion

From fabric selection and knitting to dyeing, cutting, sewing, decoration, quality inspection, and final packaging, the T-shirt manufacturing process is a repeatable workflow with clear checkpoints.

Understanding how T-shirts are made helps brands make better decisions about fabric, fit, printing method, production cost, MOQ, and delivery timeline. It also helps avoid common problems such as shrinkage, poor neckline shape, print failure, color difference, and measurement inconsistency.
