Gray cloth price calculation
Gray fabric price calculation
1. Gray fabric quotation = raw material cost + previous report + weaving quotation
2. Frontline quotation
Sizing yarn: polyester FDY 0.03～0.04 yuan
DTY Network
0.04～0.05 yuan
Nylon FDY 0.05～0.06 yuan
Rayon 0.1 yuan/combination
about
Total number of roots
(1) Union number =——————————(take an integer)
The number of raw material bobbins in the upper row (usually 1680)
Example: 8000/1680=4.76=5 and
(2) Sized yarn: FDY (except monofilament), DTY, DTY (network yarn, including light mesh, medium mesh), rayon, cotton yarn
(3) Twisting: The general market price is about 300 yuan/ton ==﹥0.0003 yuan/twist.g
The cost of twisting = the amount of twisting raw materials * twist degree * 0.0003 yuan/twist.g
① Sectional warping 0.1～0.5 yuan/M Twisted warp yarn
② DTY network wire (heavy network), monofilament, stranded wire. Spandex covered yarn 0.06～0.1 yuan/M
Example 1. Sutra: 50D glossy FDY 15,000 yuan/ton
Weft: 75D DTY
16T/2S2Z 15,500 yuan/ton
Asking: What is the cost of raw materials? Front quote?
calculate:
=18*5*168*50/9000*(1+6%)＝89.04g/m
Twist shrinkage = 0.0038 * (1.6) 2 * 75/10 = 7.3%
Weft=34*168*75/9000*(1+10%)*(1+7.3%)*(1+5%)=58.99g/m
Twist cost=58.99 * 16 *0.0003=0.0283 yuan/m
18 * 5 * 168
Number of unions=————————=9 unions
1680
Sizing fee = 9 * 0.03 = 0.27 yuan/m
Funding = 89.04 * 0.015 = 1.336 yuan/m
Weft fee = 58.99 * 0.0155 = 0.9143 yuan/m
Raw material cost = 2.2503 yuan
Preliminaries = 0.27+0.0283 = 0.553 yuan
B 150D DTY net 12T/CM 15,800 yuan/ton
Weft arrangement: 4 A and 1 B, 17# * 5 in * 166cm
32 pieces/cm
Crystal satin
calculate:
Funding=17*5*166*50/9000*1.06*0.015=1.246 yuan
Weft fee A=32*166*75/9000*1.08*4/5*0.016=0.612 yuan/m
Weft fee B=32*166*150/9000*1.08*1/5*(1+0.0038*1.2*1.2*150/10)*0.0158=0.327 yuan/m
Twisting cost = 32*166*150/9000*1.08*1/5 * (1+0.0038*1.2*1.2*150/10)*1.05*12*0.0003＝0.078 yuan/m
The number of unions=17*5*166/1680=8.3988=9 unions
Sizing fee = 9*0.03 = 0.27 yuan
Weaving fee = 32*0.02 = 0.64 yuan
Quotation=1.246+0.612+0.327+0.27+0.64+0.078=3.173 yuan/m
- Weaving shrinkage = gray fabric weft density * basic texture coefficient * (1 + crepe increase rate)
________
Basic weave coefficient = weave coefficient * ↙D number of weft threads
Texture coefficient: plain weave 146*10 to the -6th power
Three twills
137*10 to the power of 6
Four twills
128*10 to the power of 6
Five twills
120*10 to the power of 6
Crepe increase rate
Crepe warp and weft 4～9T/cm 10～19T/cm 20T/cm and above
50%
80%
100%
Flat warp and weft 40% 70% 90%
Twill satin
Crepe warp and weft 30% 40% 50%
Flat warp and weft 20% 30% 40%
Example 1.
75D Glossy FDY * 100D DTY 16T/2S2Z
12# * 5 pieces * 165cm 30 shuttles
Shrinkage rate=30*120*10 to the 16th power*100 square root=3.6%
Shrinkage rate=30*120*10 to the 16th power*100 square root*(1+30%)=4.68%
- Gray cloth defects: (grey cloth inspection)
(1) Breaking the warp and weft
(2) Rough weft
(3) Insufficient spray weft
(4) Overlapping weft
(5) Elastic gear
(6) Raw material files
(7) Longitudinal willows (wide and urgent), caused by uneven tension
(8) Intricacy, wrong pattern, wrong reed, wrong twist, wrong raw materials, wrong arrangement
(9) Reed Road (Reed Willow)
(10) Defective edges (burr edges, stepped edges)
(11) Door width is uneven
(12) Stains
