Jersey knit is the most widely used fabric construction in T-shirt manufacturing worldwide. Understanding its structure, properties, and variations is essential for Southeast Asian exporters looking to sell on Alibaba.com with confidence and credibility.
What Is Jersey Knit Fabric?
Jersey is a single-knit fabric characterized by a smooth, flat face side and a textured, looped back side. This construction creates several distinctive properties that make it ideal for everyday casual wear:
- Single-knit structure: Loops interlock in one direction, creating stretch and recovery
- Smooth face, textured back: Professional appearance on the outside, comfortable texture against skin
- Natural drape: Falls away from the body without clinging
- Moderate stretch: Typically 20-40% stretch depending on fiber composition
- Breathability: Open knit structure allows air circulation
Jersey Fabric Weight Classifications
Jersey fabric weight is measured in grams per square meter (GSM) or ounces per square yard (oz). Different weights serve different market segments:

Breathability: The Critical Feature for Southeast Asian Markets
Breathability refers to a fabric's ability to allow air and moisture vapor to pass through. For T-shirts targeting Southeast Asian, Middle Eastern, and tropical markets, breathability is non-negotiable. Jersey knit's open loop structure naturally promotes air circulation, but several factors influence actual performance:
Factors Affecting Breathability in Jersey T-Shirts:
- Fiber Content: 100% cotton jersey offers superior breathability compared to polyester blends
- Knit Density: Looser knits breathe better but may sacrifice durability
- Fabric Weight: Lighter weights generally breathe better, but heavyweight jersey can also be breathable if properly constructed
- Finishing Treatments: Some chemical finishes can reduce breathability
- Moisture Wicking: Natural fibers absorb moisture; synthetic fibers can be engineered to wick
