What should be noted when producing luggage netting using warp knitting technology?

The production of knitted mesh fabrics for luggage and bags requires focused attention on three core aspects: material selection, process control, and quality inspection. This ensures products combine strength with aesthetic appeal.

Material Selection

- Abrasion Resistance: Prioritise high-abrasion-resistant materials such as nylon and polyester to minimise wear risks during prolonged use.

- Tear Resistance: Select three-layer mesh or diamond-patterned structures, employing stress-distribution designs to enhance tear resistance.

- Lightweighting: Control denier (e.g., 70D, 210D) and thickness to balance strength with portability.

Process Control

- Warp knitting parameters: Adjust stitch pitch (recommended 6-8 stitches/inch) and yarn tension to ensure uniform mesh without yarn slippage.

- Heat treatment: Maintain setting temperatures between 140-190°C to stabilise yarn structure and enhance UV resistance.

- Surface treatment: Apply PU coating or eco-friendly adhesives (e.g., TPE) to improve waterproofing while preventing excessive hardness that compromises tactile feel.

Quality inspection

- Yarn breakage inspection: Conduct real-time checks during production to identify broken threads or pilling, preventing defects from progressing to subsequent stages.

- Mechanical Testing: Verify the fabric's elongation at break through tensile testing to ensure load-bearing components meet design specifications.

- Visual Inspection: Assess mesh symmetry, edge flatness, and colourfastness (must comply with EU non-azo dye standards).
