Water quality standard for water jet loom
Optimum water quality standard
Allowable water quality standard
Impact on weaving and weaving machines
Organic matter: animal and plant debris, corrosive soil, microorganisms
Inorganic matter: clay, rock, soil microparticles; iron, manganese and other oxides
Attached to rust, rust, corrosion, clogging, stains on the fabric
Corrosive and corrosive due to acidic or alkaline water, the slurry is desizing due to alkaline water
The weft insertion may be caused by the adhesion of water rust on the nozzle; the electric rust is attached to the electric rust, which causes poor weft insertion, which makes the insulation of the weft detector low.
All iron and manganese ions
Free chlorine molecule
Strong corrosive and strong oxidizing power
The biggest cause of corrosion, causing damage to the pump spring
Condensate (NaHCO3), etc. due to softening treatment of hydrogen carbonate ion HCO3
Does not cause direct effects on fabrics, etc.
Potassium permanganate consumption（COD）
Organic matter, bacteria, mold, etc.
Corrosion, stains on the fabric, falling pulp, low film strength
Total amount of impurities in water
Cause various faults
Conductivity between electrodes that are spaced apart in water (depending on the electrolyte dissolved in the water)
If it is obviously low, the function of the power-on weft detector will be impaired; if it is too high, it means that there are too many impurities in the water, which increases the electric corrosion of the probe.
If it is too high, the phenomenon of falling pulp increases, and the bacteria are easy to multiply; if it is too low, the strength of the slurry, wax, etc. is low. Too high or too low will cause the weft insertion performance to drop.
