  • Screen printing: Screen printing is the ideal choice for large uniform orders (usually from 100 shirts or more) with simple designs and few colors (from 1–4 colors). If you want durability, vibrant colors, and reasonable cost, screen printing is an excellent solution.
  • Heat transfer vinyl (decal):
     Suitable for small quantities (under 20 shirts), multi-color or detailed designs, and urgent orders.
     This method is also ideal for printing names, numbers, or personalized details on shirts.
  • Heat transfer printing: Heat transfer is perfect for polyester fabrics or high-polyester-content fabrics (from 65% or more).
     If you want high-contrast colors, vivid tones, durability, and no cracking or peeling, heat transfer is an optimal choice.
  • Flexographic printing:
     Flexographic printing is a versatile solution suitable for most fabrics and all designs, with no limitation on the number of colors or design complexity. If you need fast production, sampling, or gradient/transition designs, this method is worth considering.

DTG printing:
 Suitable for complex, artistic designs printed directly on shirts in small quantities and applicable to various fabric types.

2.4. Guide to Choosing the Right Fabric Material

Choosing the right fabric material should not be based only on personal preference — it is also influenced by factors such as intended use, working environment, job characteristics, budget, and technical requirements. Below are some helpful suggestions to help you make accurate decisions:

Purpose of Use

Depending on the type of uniform and its purpose of use, you should choose the appropriate fabric. For company uniforms, it is recommended to prioritize fabrics with high durability, wrinkle resistance, and a neat, elegant appearance, such as Kate, Kaki, or 2-way cotton. For sports uniforms, fabrics that have good sweat absorption, good elasticity, and quick-drying capability, such as honeycomb cotton, polyester, or bird-eye mesh fabric will be the most suitable choice.

Meanwhile, protective work uniforms require fabrics with high durability, good absorbency, and resistance to heat, fire, or chemicals, depending on the nature of the job. For student uniforms, it is advisable to choose fabrics that are soft, skin-friendly, safe to wear, and capable of absorbing sweat well such as cotton or honeycomb cotton.

Working Environment

The working environment also has a significant influence on fabric selection. In office environments, you can choose fabrics that are soft, wrinkle-resistant, and tidy such as Kate or 2-way cotton. On the other hand, if you frequently work outdoors, you should prioritize fabrics that are cool, breathable, have good sweat absorption, and dry quickly such as honeycomb cotton, polyester, eco-cafe fabric, or bird-eye mesh fabric.

Nature of Work

The nature of the job is also an important factor to consider. Jobs that require frequent movement should use fabrics that have elasticity, good sweat absorption, and do not cause discomfort when moving, such as honeycomb cotton or 4-way stretch cotton. Conversely, jobs that require neatness and formality should use fabrics that hold their shape well, resist wrinkles, such as Kate, Kaki, or 2-way cotton.

Budget

The budget also plays a crucial role in fabric selection. If the budget is limited, you can choose affordable fabric types such as polyester pique or bird-eye mesh fabric. In cases where the budget is more generous, investing in higher-end fabrics such as 2-way cotton, 4-way cotton, or eco-cafe fabric will significantly improve the overall product quality.

Technical requirements

Printing techniques have a direct impact on fabric selection. If heat transfer printing is used, the fabric needs to have a high polyester content (from 65% or more), such as polyester pique. For screen printing, most fabric types are suitable, but the best results are achieved when printing on cotton.

Digital printing (DTG) is flexible with many types of fabrics. Meanwhile, embroidery is best suited for thick and firm fabrics such as cotton pique, polyester pique, Kate, or Kaki. Avoid embroidering on fabrics that are too thin or highly stretchable, as this can cause stitch distortion or fabric wrinkling.

2.5. Common Issues When Choosing Fabrics

Fabric Pilling

Color Fading

Fabric Shrinkage

Skin Irritation

Cause
Poor fiber quality, improper weaving techniques, or friction during wear and washing.

Cause
Poor-quality dye, fabric not being properly color-fixed, or washing at high temperatures, using strong detergents, or drying directly under sunlight.

Cause
 Due to the natural structure of the fabric fibers (especially cotton fibers), or washing and drying at high temperatures.

Cause
 Due to chemical components in fabric dyes, finishing agents, or because the fabric fibers are too rough.

Solution
Choose fabrics that are resistant to pilling with a tightly woven structure. Wash garments by hand or on a gentle machine cycle, turn them inside out before washing, avoid using hard brushes, and dry them in a cool, ventilated place.

Solution
Choose fabrics with high colorfastness that are dyed with high-quality dyes. 

Wash garments with cold or lukewarm water (below 40°C), avoid strong detergents, turn the garment inside out when drying, and dry it in a cool, ventilated place away from direct sunlight.

Solution
Choose fabrics that have been pre-shrunk or those with low shrinkage. Wash the garment with cold water, avoid high-heat drying, and lay the garment flat when drying to prevent stretching.

Solution
Prioritize natural fabrics or fabrics that are certified as safe for the skin. Wash the garment before wearing it for the first time to remove dust and residual chemicals from the production process.

If your skin is highly sensitive, try washing the garment with mild detergents that are fragrance-free and do not contain color additives.
