Water jet looms excel in producing fabrics where synthetic fibers and high speed matter most. Here's what they're built to weave:
1. Lightweight Synthetic Fabrics
Umbrella/Tent Fabric: Woven from nylon or polyester filaments, water jet weft insertion does not damage the coating, resulting in tear resistance.
Lining Fabric (Polyester Pongee, Polyester Taffeta): Water jets maintain low tension, resulting in a smooth, scratch-free surface and stable shrinkage during dyeing and finishing.
2. Functional Fabrics
Down-Proof Fabric: High-pressure water jets ensure a weft density exceeding 180 picks per inch, eliminating down penetration (a critical layer in down jackets).
Filter Mesh Fabric: Water jets precisely control pore uniformity, surpassing the airflow disturbances of air jet looms.
3. Industrial Fabrics
Conveyor Belt Carcass: High-strength polyester yarns remain in place under high-speed water jets, enhancing the belt base's tensile strength.
Waterproof Base Fabric: A glass fiber + polyester blend. Water jets do not generate static electricity, preventing fiber breakage.
4. Specially Structured Fabrics
Sandwich Mesh: Double-layered, water flows through the middle layer's connecting yarns without deflection (a staple in athletic footwear).
Linen-like Texture: Variable water pressure creates an irregular weft pattern, resulting in a natural linen-like feel.
| Category | Key Fabrics | Water Jet Advantage | Critical Constraints |
| Light Synthetics | - Umbrella nylon- Taffeta lining- Chiffon | Gentle tension preserves fiber integrity; perfect for coatings | Avoid hydrophilic additives – causes waterlogging |
| High-Density | - Down-proof fabrics- Microfiltration cloth | Achieves 180+ wefts/inch; precise pore control | Only continuous filaments (no spun yarns) |
| Industrial | - Conveyor belt cores- Composite base cloth (fiberglass) | Handles 1000D+ heavy yarns without abrasion | Glass fibers require ceramic-coated nozzles |
| Structural | - 3D spacer mesh (footwear)- Imitation linen | Water penetrates layers without distortion | Variable pressure creates intentional slubs |
| PROHIBITED | - Pure cotton/linen- Wool fleece- Spandex blends | Fibers swell/break in water Elastomers degrade Hydrophilic fibers jam systems | Never attempt – clogs nozzles in <30 minutes |
