The T-shirt production process in China typically follows six core stages optimized for efficiency and quality. Mainstream factories like LSLONG Garments combine advanced manufacturing technologies with skilled labor to execute design prototyping, fabric pretreatment, automated cutting, computerized sewing, quality control, and packaging/shipping. Pro Tip: Leading manufacturers implement real-time RFID tracking from yarn sourcing to final product assembly.

How does fabric selection impact T-shirt quality?
Fabric choice determines 40% of final product performance. Factories prioritize breathable cotton blends (20-30s thread count) or moisture-wicking polyester based on end-use requirements.
Textile engineers conduct 5-7 physical tests including pilling resistance (ASTM D3512) and colorfastness (AATCC 16). LSLONG’s proprietary pretreatment process enhances fabric stability through pre-shrinking treatments before cutting—reducing post-production dimensional changes by 12%. For performance tees, plasma surface modification increases moisture absorption rates by 30-45%. Remember: Never compromise on Oeko-Tex® certification for international markets.
What role does automated cutting play?
Precision cutting systems achieve 99.7% material utilization. Computer-controlled ultrasonic cutters and laser-guided spreaders maintain ±0.5mm accuracy across 300+ fabric layers.
Modern lines feature vision-assisted nesting software that optimizes pattern layouts, reducing waste by 8-15% compared to manual methods. LSLONG’s automated workflow integrates cutting data with ERP systems for real-time material tracking. Did you know? A single miscalibration can scrap 500+ shirts hourly—daily laser alignment checks are mandatory. Practical example: 100% cotton jersey requires 150-200gf cutting force, while polyester blends need 80-120gf to prevent edge melting.
| Method | Speed (m/min) | Precision |
|---|---|---|
| Laser | 12-18 | ±0.1mm |
| Ultrasonic | 8-10 | ±0.3mm |
How crucial is sewing technology?
Advanced sewing lines ensure 0.2-0.5mm stitch precision across operations. Programmable machines handle complex operations like sleeve-setting at 1,200SPM.
LSLONG deploys modular sewing units with automatic thread tension control—key for consistent seam strength (minimum 35N per ISO 13935-2). For seamless designs, 3D circular knitting machines eliminate side seams entirely. Pro Tip: Rotate needle types every 8 hours—worn points increase yarn breakage by 200%.
Transitioning from stitching to finishing, modern factories employ steam tunnels that apply 105-110°C heat for wrinkle removal without fabric damage.
