Product Core Performance Parameters
Defining application boundaries, production process parameters, service life, and quality stability. Vomelt’s full range of hot melt products uses six core technical indicators as quality criteria to ensure seamless bonding, weather adaptability, and washing durability.
Six Core Performance Indicators
All performance data are calibrated according to national and international standards. Batch stability is strong, and test reports are traceable.
Breathability
Determines wearing dryness, sweat wicking, and anti-mugginess. Achieved through structure (web, textured film, dot film).
Washing Resistance
Core durability indicator. Quantifies resistance to hydrolysis, delamination, and debonding under various washing conditions.
Melting Range
Core process parameter. Affects bond strength and process defects. Wider range means higher production tolerance.
Transparency / Clarity
Evaluates light transmittance, haze, and bonding flatness. Key for light-colored fabrics, mesh, and luxury apparel.
Elasticity / Recovery
Determines wearing comfort, wrinkle resistance, and shape retention. High-rebound materials leave no residual deformation.
Temperature Resistance
Core indicator for outdoor products. Evaluates resistance to softening, debonding, and brittle fracture under extremes.
Complete Product Line Performance Comparison
Standardized star rating based on laboratory conditions (23℃, 50% relative humidity). Use directly for product selection and production parameter setting.

- Best Choice: TPE textured film > TPU high-elastic web
- Why: TPE has excellent skin feel, no odor, seamless appearance, dry breathability.
- Avoid: PA, PES, EVA (stiff, no elasticity, stuffy).
High-temperature Wash & Shaping
Shirts, collars, cuffs, waistbands, home textiles.
- Key Focus: Washing resistance, melting stability, shaping ability.
- Best Choice: PA / PES film & web
- Why: High rigidity, durable crispness, resists high-temp washing. No deformation.

Common Defects & Optimization
Based on frequent mass production issues, identifying root causes and practical solutions.
| Observed Defect | Performance Root Cause | Solution |
|---|---|---|
| Fabric feels stuffy, sweat sticks to body after lamination | Insufficient breathability, wrong use of non-breathable solid film | Switch to TPE textured breathable film or high-breathability hot melt web |
| Debonding, delamination, whitening, edge curling after washing | Insufficient washing resistance, weak hydrolysis resistance | Upgrade to TPE/PA/PES high washing resistance materials |
| Poor bonding, glue bleed-out, charring, strike-through | Mismatch between melting range and production temperature | Strictly follow standard melting range for lamination parameters |
| Adhesive marks, heavy haze, poor clarity after bonding | Insufficient transparency, high haze of the material | Switch to TPU/TPE ultra-clear seamless film |
| Loosening, deformation, no recovery, edge curling after stretching | Poor elasticity, high residual deformation, weak fatigue resistance | Switch to TPU/TPE high-elastic series |
| Debonding under high-temp exposure; stiff and brittle fracture under low temp | Temperature range does not match use scenario | For high temperature: PES/PA; for low temperature: TPE/TPU |
