Surat ke grey kapde ka bada hissa waterjet aur airjet loom pe banta hai. Dono shuttle-less loom hain — vana (weft) shuttle se nahi, ek jet se paar jaata hai. Fark yeh hai ki jet paani ka hai ya hawa ka. Isi se tay hota hai ki kaunsa yarn chalega, kitni bijli lagegi aur maintenance kaisa hoga.
Vana kaise daalte hain
Waterjet
Nozzle se paani ki patli dhaar nikalti hai aur vane ko shed ke paar le jaati hai. Har pick pe thoda paani lagta hai, isliye kapda geela utarta hai aur loom ke paas paani ka pump, filter aur nikasi chahiye.
Airjet
Main nozzle se compressed hawa vane ko dhakka deti hai, aur reed ke saath lage relay (sub) nozzle use poori chaudai tak le jaate hain. Hawa compressor se aati hai — airjet ki asli "machine" compressor bhi hai.
Kaunsa kapda kis pe
- Waterjet: vana aisa chahiye jo paani na sokhe — polyester aur nylon filament (FDY, DTY wagairah). Halke se madhyam filament kapde ke liye sabse aam.
- Airjet: range zyada chaudi — filament ke saath spun yarn, viscose, cotton aur blend bhi. Viscose ya spun vana paani sokh leta hai, isliye woh waterjet pe theek nahi udta.
Pick ki range, chaudai aur design (dobby, jacquard) loom ke model pe nirbhar hai — aapke loom ki company ke hisaab se check karein.
Production per shift
Dono pe formula ek hi hai:
Aam taur pe airjet zyada RPM pe chalta hai. Surat mein dikhne wali range moti-moti: waterjet kuch sau se lekar lagbhag 800–900 RPM, airjet aksar usse upar. Asli number loom ke model, chaudai aur quality se badalte hain — aapke loom ki company ke hisaab se check karein.
Udaharan
Ek hi 50 pick ki quality, 85% efficiency, 12 ghante ki shift, do shift roz. Waterjet 650 RPM pe, airjet 850 RPM pe (dono sirf udaharan).
- 1 meter ke pick: 50 × 39.37 = 1,968.5
- Waterjet: 650 × 60 × 12 × 0.85 = 3,97,800 pick ÷ 1,968.5 = 202.08 m / shift, roz 404.17 m
- Airjet: 850 × 60 × 12 × 0.85 = 5,20,200 pick ÷ 1,968.5 = 264.26 m / shift, roz 528.52 m
Apne loom ke number Loom Production calculator mein daalo — din, mahina aur poore unit ka meter bhi milega.
Bijli, paani aur hawa
Waterjet mein bijli loom ki motor aur paani ke pump mein jaati hai. Airjet mein loom ki motor ke saath compressor ka bada hissa judta hai — isliye airjet ka kul load per loom aam taur pe waterjet se kaafi zyada hota hai. Zyada meter is kharche ko kuch had tak baant deta hai, isliye fark ₹ per meter mein dekho, ₹ per din mein nahi.
Udaharan (sirf samajhne ke liye)
Maan lo waterjet ka load 2.5 kW aur airjet ka compressor milake 6 kW, bijli ₹8 per unit (udaharan rate), 24 ghante:
- Waterjet: 2.5 × 24 × 8 = ₹480 roz ÷ 404.17 m = ₹1.19 / m
- Airjet: 6 × 24 × 8 = ₹1,152 roz ÷ 528.52 m = ₹2.18 / m
Apne asli kW aur rate Power cost per meter mein daalo. Poora hisaab loom ki bijli guide mein.
Waterjet ko roz bahut saara saaf paani chahiye — filter, softening aur recycling ka intezaam, aur kapda sukhane ka bhi. Airjet ko sookhi, saaf hawa chahiye — dryer, filter aur leak-free pipe line. Spun aur viscose ke liye hall ki humidity bhi sambhalni padti hai.
| Waterjet | Airjet | |
|---|---|---|
| Vana | Polyester, nylon filament | Filament, spun, viscose, blend |
| Speed | Achhi | Aam taur pe zyada |
| Bijli per loom | Kam | Zyada (compressor) |
| Zaroorat | Saaf paani, nikasi | Compressed hawa, humidity |
| Dhyaan | Jung, nozzle, pump, paani | Nozzle, reed, compressor, leak |
Maintenance
- Waterjet: paani ki quality sabse badi baat — ganda paani nozzle band karta hai aur parts pe jung lagata hai. Filter, pump aur nozzle ki safai tay din pe.
- Airjet: hawa ka pressure sthir rakho, leak dhundo, compressor ki service time pe, nozzle aur profile reed saaf.
Aam galtiyaan
- Sirf RPM dekhna. Zyada RPM tabhi kaam ka hai jab efficiency bhi tike — toot badhe toh meter ghat jaata hai.
- Compressor ka kharcha bhoolna. Airjet ki bijli mein compressor ka hissa joda nahi toh costing galat.
- Har vana waterjet pe chalana. Paani sokhne wala vana waterjet pe toot aur kharab kapda deta hai.
- Brochure ke number pe plan. Apne unit ke ek hafte ke asli meter se plan banao.
- Paani aur sukhaane ka kharcha chhodna. Waterjet mein pump, filter aur nikasi bhi cost hai.

Loomiro mein
Loom master mein har loom ka type (waterjet, airjet ya doosra) aur RPM ek baar. Taka Entry ke meter se har loom ki efficiency Loom page pe 30 din ke chart ke saath dikhti hai, aur machine efficiency report mein saare loom ek saath — toh dikh jaata hai ki kaunsa loom ya kaunsi quality peeche hai. Costing mein loom ka kW aur bijli ka rate daal ke har quality ki bijli per meter bhi nikalti hai.
Yahan ke RPM, kW aur rate sirf udaharan hain. Apne loom ke number uski company ke manual aur apne bijli ke meter se lo.
