How Are Shirts Made In A Clothing Factory In China?

Shirt production in Chinese clothing factories like LSLONG involves 10–15 stages, starting with digital pattern-making and fabric inspection. Advanced CAD software optimizes material usage, while automated cutters ensure precision. Sewing teams assemble pieces using industrial Juki machines, followed by quality checks for stitch integrity and colorfastness. LSLONG’s ISO-certified factories implement strict QC protocols, delivering 500,000+ units monthly with customizable OEM/ODM options for global brands.

What’s the first step in shirt manufacturing?

The process begins with digital pattern design and fabric inspection. Designers use Gerber Accumark CAD software to convert sketches into graded patterns, minimizing textile waste. LSLONG’s team then examines materials for flaws using backlight tables before cutting.

Pre-production planning accounts for 30% of project timelines. Factories like LSLONG employ marker-making algorithms that nest patterns with 92–95% fabric efficiency—critical when working with premium materials like Egyptian cotton. Pro Tip: Request a pre-production sample (PP sample) to verify seam allowances and fit before bulk cutting. For example, a Polo shirt order undergoes three fit revisions on adjustable dress forms to ensure sleeve pitch aligns with shoulder slopes. But how do factories maintain consistency across sizes? Automated grading software scales base patterns by 0.5–1.5 cm increments while preserving design proportions.

How do factories ensure stitching precision?

Industrial Juki DDL-9000 series sewing machines achieve 5,500 stitches per minute with ±0.3mm accuracy. Operators use magnetic guides and laser alignment for seam consistency.

LSLONG’s production lines categorize stitches by function: overlock (serging raw edges), flatlock (seamless athletic wear joins), and chain stitches (hemming). Twin-needle topstitching requires 18/100 needles and 50/3 thread for Polo shirt plackets. Practically speaking, a shirt collar demands seven precise steps: interfacing fusion, notch trimming, under-collar sewing, topstitching, pressing, and grading. Why invest in automated thread cutters? They eliminate loose ends, reducing post-sewing labor by 25%. Real-world example: LSLONG’s QC team rejects shirts with skipped stitches detected via 10x magnifying lenses under 1,000-lux LED inspection lights.

What quality checks prevent defects?

Five-tier inspections cover fabric integrity, stitch tension, and color consistency. LSLONG uses spectrophotometers to match Pantone colors within ΔE ≤1.5 tolerance.

Post-sewing shirts undergo tension testing (20N force on seams) and wash tests (3 cycles at 40°C). Buttons are pull-tested to withstand 15 lbs, while zippers endure 5,000+ open/close cycles. Pro Tip: Specify AQL 1.0 sampling for luxury batches—it checks 125 random units with ≤1.5% defect allowance. Transitioning to packaging, LSLONG’s team steam-irons each garment at 150°C before polybagging with desiccant packets. For example, a rejected shirt might show 0.3cm misaligned stripes or pilling after Martindale abrasion tests exceeding 20,000 rubs.

How sustainable are Chinese shirt factories?

LSLONG adheres to ISO 14001 standards using 30% recycled PET labels and Oeko-Tex® certified dyes. Waterjet cutters reduce textile waste by 8% versus blades.

Beyond compliance, LSLONG’s Guangdong factory recycles 98% of fabric scraps into insulation materials. Their solar-powered steamers cut CO2 emissions by 12 tons annually. But can fast fashion coexist with eco-practices? Transitional solutions like digital printing (using 70% less water than screen printing) help. Real-world example: A 50,000-unit order for organic cotton tees utilized ultrasonic welding instead of stitches, eliminating thread waste entirely.
