Yarn aapka hai, beam warper banata hai. Beech mein yarn ka hisaab sirf ek tareeke se pakka hota hai: beam ka vajan. Formula se pata chalta hai kitna yarn beam pe hona chahiye, kaante se pata chalta hai kitna hai.
Formula
90,00,000 kyun?
Denier = 9,000 meter dhaage ka vajan gram mein. Beam pe har taar utne meter ka hai jitna beam ka meter, toh kul dhaaga = taar × meter. Isko 9,000 se bhaag do aur denier se guna karo toh gram milte hain; gram ko kg banane ke liye phir 1,000 se bhaag. 9,000 × 1,000 = 90,00,000. Bas itni si baat hai.
Udaharan 1 — seedha filament yarn
6,400 taar, beam 7,500 meter, tana 75 denier.
- 6,400 × 7,500 × 75 ÷ 90,00,000 = 400 kg
Udaharan 2 — two-ply (do dhaage mila ke)
4,800 taar, beam 6,000 meter. Tane mein 75 denier ke do dhaage twist karke ek banaya gaya hai.
- Do-ply ka denier ≈ 75 × 2 = 150 denier
- 4,800 × 6,000 × 150 ÷ 90,00,000 = 480 kg
Twist dene se dhaaga thoda chhota hota hai, isliye asli denier 150 se thoda zyada aata hai. Supplier se twist ke baad ka (resultant) denier pooch lo, woh sabse sahi.
Udaharan 3 — count wala yarn (2/40s cotton)
3,000 taar, beam 5,000 meter, tana 2/40s — yaani 40s ke do ply, jo lagbhag 20s jitna mota hai.
- Denier = 5,315 ÷ 20 = 265.75
- 3,000 × 5,000 × 265.75 ÷ 90,00,000 = 442.92 kg
Agar galti se "40" ko denier maan liya toh jawab 66.67 kg aata — lagbhag saat guna kam. Count se denier yarn count converter mein nikalo; poori baat denier vs count mein.
Warper ka beam kaise check karein
Beam aate hi kaante pe chadhao. Khaali beam (flange ke saath) ka vajan pehle se pata hona chahiye — har beam ka alag ho sakta hai, isliye flange pe likh ke rakho.
Fark % = (net yarn − formula ka kg) ÷ formula ka kg × 100
Asli meter (lagbhag) = net yarn × 90,00,000 ÷ (taar × denier)
Udaharan
Udaharan 1 wala beam: formula se 400 kg. Kaante pe bhara beam 532 kg, khaali beam 140 kg → net 392 kg.
- Fark: (392 − 400) ÷ 400 × 100 = −2%
- Asli meter: 392 × 90,00,000 ÷ (6,400 × 75) = 7,350 m — card pe 7,500 likha hai, yaani lagbhag 150 meter kam
Fark aaye toh in cheezon ko ek-ek karke dekho:
- Taar. Creel pe kitne cone lage the, kitne section bane — beam card ke taar se milao.
- Meter counter. Warping machine ka counter galat ho toh har section chhota ya lamba.
- Denier ka lot. Naya lot patla ya mota aaya ho toh vajan badal jaata hai, chahe taar aur meter sahi ho.
- Sizing. Sized beam pe size ka vajan bhi chadhta hai, isliye woh formula se bhaari aata hai. Sizing wale beam ka normal fark apne pichle beam se tay karo.
Saath mein yarn ka milan bhi karo: warper ko diya yarn − beam ka net yarn − wapas aaya yarn = wastage. Har beam pe yeh number likhoge toh pata chalega kaunsa warper zyada wastage dikha raha hai.
Aam galtiyaan
- Khaali beam ka vajan andaaze se ghatana. 5 kg ka galat andaaza bhi 400 kg pe 1.25% ka fark bana deta hai.
- Kapde ka meter daal dena. Formula mein beam pe tane ka meter aata hai, kapde ka nahi. Kapda crimp ki wajah se kam banta hai — woh hisaab beam se taka guide mein.
- Count ko denier samajhna. Udaharan 3 dekho — fark lagbhag saat guna ka.
- Two-ply ko ek dhaage ka denier. 2 × 75 wala tana 75 denier nahi, kam se kam 150 hai.
- Kinare ke taar bhoolna. Taar ginte waqt selvedge bhi jodo — reed aur pick se ends dekho.
Loomiro mein
Loomiro ke Beam Stock mein har beam ke taar, meter aur denier daalo — vajan khaali chhodo toh taar × meter × denier ÷ 90,00,000 se apne aap nikal jaata hai, aur kaante ka vajan ho toh woh daal sakte ho. Beam card print hota hai, aur beam loom pe chadhte hi Bhidan mein expected taka dikhte hain. Beam se kitne taka banenge, woh Beam → Taka calculator mein — wahi calculator beam ka kg bhi deta hai.
Formula ka vajan sookhe, bina size ke yarn ka hai. Moisture aur size se asli beam thoda alag aata hai — apne unit ka normal fark pichle beam se tay karo.
