Before fabric consumption calculation we should know some terms-
Wastage for woven fabric = 5 % (for woven unit will be yards)
Wastage for knit fabric = 10% (for knit unit will be kg)
Knit Fabric Consumption Calculation:
Let say,
O/Q = 5000 pcs, Fabric consumption = 2.6 kg/dz. Calculate total fabric requirement for that order?
We know that,
Fabric requirement = {(Cons /dz divided by 12) * O/Q } + Wastage
= {(2.6/12 ) * 5000} + 10%
= 1191.67 kg
Woven Fabric Consumption Calculation:
Let say,
O/Q = 4000pcs, fabric consumption = 2.6yd/dz. Calculate total fabric requirement for that order?
We know that,
Fabric requirement = {(Cons /dz divided by 12) * O/Q} + Wastage
= {(2.6/12) * 4000} + 5%
= 910 yards
Sewing Thread Consumption Calculation:
Before sewing thread consumption we should follow some terms –
- Wastage for woven and knit 15%
- 50/2 Means –50 count, 2 ply =4000m. (Just only for knit fabric )
- Woven = (40/2 down = 4000 m, 20/2 up = 3000m)
Let Say,
O/Q =5000 PCS, Thread Consumption = 160m/grmt50/2. Calculate Total No Of Cones Required For That Order?
We know that,
Cone requirement = {(CONS /Gmt * O/Q)/quantity of thread} + Wastage
= {(160*5000) / 4000} + 15%
= 230 cone
Let Say,
O/Q =5000 PCS, Thread Consumption =200 m/grmt, 20/2=80 m, 40/2=120m. Calculate Total No Of Cones Required For That Order?
For 40/2 (bottom + bobbin) require of cone,
= {(CONS/Gmt * O/Q)/quantity of thread} + wastage
= {(120*5000)/4000} + 15%
= 172.5 cone
= 173 CONE
For 20/2 ( TOP+NEEDLE ) require of cone,
= {(80*5000)/3000} + 15%
= 153.33 cone
= 154 cone
Button Consumption Calculation for Garments:
Before calculation of button for garments we should follow some terms-
1 dzn = 12 pc
In case of metal button,
1 gross (g) = 12*12 = 144 pc
Wastage = 6%
For plastic button,
1 great gross (gg)
= 144*12
= 1728 pcs.
Wastage = 5%
Button Consumption Calculation for Garments:
Let Say,
O/Q =5000 PCS, plastic button required =12 pcs/grmt. Calculate Total number of plastic button Requirement For That Order?
Plastic button requirement,
= {(CONS /Gmt * O/Q)/ great gross} + Wastage
= {(12*5000)/1728} + 5%
= 36.46 GG
Note: in button don’t add number before decimal such as 36.
Let Say,
O/Q =5000 PCS, metal button required =4 pcs/ grmt. Calculate Total number of metal button Requirement For That Order?
Metal button requirement = {(CONS /Gmt * O/Q)/ gross} + Wastage
= {(4*5000) / 144} + 6%
= 147.22 G
Lace/All Kinds of Tape Consumption Calculation for Garments:
Suppose, O/Q =5000pcs, Lace Consumption =10” /Garment, Calculate Lace Requirement For That Order ( 5 Percent ) Wastage.
Solution:
Lace Required = { (Cons/Gmt* O/Q)/ 36} + Wastage
= {(10*5000)/36} + 5%
= 1458.33
=1459 Yds.
Suppose, O/Q = 5000pcs, IN Consumption =2.40 YDS / Dz. Calculate Interlining Requirement For That Order ( 5 Percent ) Wastage.
Solution:
Interlining Required = { (Cons/Dz /12) *O/Q } + Wastage
= {(2.40/12*5000)} + 5%
= 1050yds
Size Label Consumption Calculation for Garments:
Suppose, O/Q = 5000pcs, Size Range S To Xl. Size Ratio =1:1:2:1
Calculate Size Label Requirement For That Order (5 Percent ) Wastage.
Solution,
Qty of S = { (0/Q *Individual Ratio)/Some Of Total Ratio} + Wastage
= {(5000*1)/5}+ 5%
=1050
Qty Of M = { (0/Q *Individual Ratio)/Some Of Total Ratio} + Wastage
= {(5000*1)/5} + 5%
= 1050
Qty Of L = { (0/Q *Individual Ratio)/Some Of Total Ratio} + Wastage
= {(5000*2)/5} + 5%
=2100
Qty Of L = {(0/Q *Individual Ratio)/Some Of Total Ratio} + Wastage
= {(5000*1)/5} + 5%
= 1050
Suppose,
O/Q = 5000pcs, Teeth clip/gmt = 3pcs. Calculate teeth clip requirement? Wastae3 %
Solution:
Interning Required = { (Cons/Gmt) *O/Q }+ Wastage
= (3*5000)+ 3%
= 1540 PCS
Suppose,
O/Q =5000 pcs, gmt tape /ctn = 6 yds. No of ctn=50
Calculate gum tape requirement? Wastage 5% .
Solution,
Gum tape require = { (gum tape /ctn* no of ctn)/qty /ctn}+wastage
= {(6*50)/50}+ 5%
=7 roll
Suppose,
O/Q = 5000pcs, piece poly will be used 25 gmt/blister poly. 4 blister poly/ctn.
Calculate poly and ctn requirement (wastage 5%)
Solution,
Piece poly requirement = O/Q + wastage
= 5000+5 %
= 5250 pices.
Blister poly require = {(O/Q)/(gmt/blister poly)} + wastage
= 210 pcs
Gmts/ctn = gmts/blister * NO Of blister /ctn
=100
Ctn requirement ={(0/q)/(gmt/ctn)}+5 %
= 50 pc
