What are the disadvantages of a water jet loom?

Water jet looms are fast and energy-saving, but factories that have used them complain that they are like "picky leopards"—fast but with many problems. The main shortcomings are as follows:

1. Limited Fabric Options

Only synthetic fibers can be woven: Natural fibers (cotton/linen/silk) swell and break when wet, making it impossible.
Afraid of hydrophilic fabrics: Artificial cotton and viscose absorb water and become heavy, making them impossible to spray.
Unable to weave heavy fabrics: The water jet cannot lift coarse yarns; canvas and denim are out of the question.
Buying this is like signing a "synthetic fiber contract"; switching to natural fibers requires buying new machines.

2. Workshops Turn into Water Curtains

Extreme humidity: The machine sprays water mist, causing dripping walls in summer and fogging windows in winter.
Constant water accumulation on the floor: Water pump seals age and leak, requiring workers to wear rubber boots.
Rusting metal parts: Bearings and screws rust, requiring three times the number of spare parts.

3. Water Quality Requirements More Delicate Than People

4. Repairing is like stirring up a hornet's nest

A clogged nozzle is a nightmare: Even a 0.1mm hole needs a needle tip to unclog it; a slight tremor from a skilled mechanic can ruin it.
Leaks are impossible to trace: Dozens of meters of water pipes are buried underground; finding the leak takes forever.
Electrical short circuits are commonplace: Moisture seeps into the control box, and circuit boards fail instantly.

5. Hidden cost pits

Rust prevention is a bottomless pit: Parts need rust-preventive oil applied weekly, using up two cans a year.
Workshop renovations are expensive: Waterproof ramps must be built on the floor, and drainage ditches must be deepened to prevent backflow.
Heating costs double: To prevent freezing in winter, workshop heating must be on 24 hours a day.
