In 1, count of yarn and knitted fabric weight what relationship? For example, 144gsm cotton plain cloth to be the number of yarn count?
In 2, knitted fabric dyeing weight range is about how much?
A currently said yarn number is mostly refers to the" English count", used for the English word " S ". It is defined as: in moisture regains, weighs a pound of yarn, its length has several 840 yards, is called a few more coarse yarn. The yarn, the S value more small, yarn is fine," S" value is greater than 1. 40S / 20S / 1 yarn fine. So, in the same structure of the knitting cloth, gauze is fine, its weight ( g / m2 ) less. As 32S / 1 plain cloth finished g in 135-145G / M2, 20S / 1 plain cloth product G lies in 180-190G / M2.
Knitting cloth passing in front of the whole, scouring, and the solution of the dye with a series of chemical reactions, is hygroscopic expansion of, it will usually gain 15-20G / M2 left and right sides. But with the fiber raw material selection, fabric structure, dyeing, dye characteristics and the degree of float. Such as: carded yarn due to impurities, of yarn, fabric has combed yarn product will be lighter than; plain cloth rib cloth coil structure is compact, cloth and dyeing weight relatively rib cloth to be small. And with the same structure of yarn cloth, weaving density may also have effect.
B in accordance with the theoretically calculated count / specifications of Mick and actually herein. The same batch production of fabrics for stenter setting treatment is slightly different, weight will bias a lot. Of course, from the factory price list to see count, size, width, weight, can roughly know certain laws. It is gram that method is not simple. Two examples.
Cotton: 40 x 40 + 40D 133 x 72 width: 48 / 50"
Setting: yarn price 33000 yuan / ton
The first step : find out the warp strip number: 133 x 50 (width ) = 6650 (with a total)
40 to 5310 ( Deniel / 40D = 133 Deniel coefficient )
6650 x 133 / 9000 ( coefficient ) = 97. 53 x 1.05 ( loss )
Yarn weight = 102G / M
The second step : find out the weft thread weight
40s + 40D = 173 Deniel x 72
= x ( 1.27+0.10m ) 12456 / 9000 x 36
= 68.26 g / M
Fabric weight: 170 g / M
Chemical products: 50D X 75D / 203 X 8966.9"
203 X 66.9 = 13580 / 9000 = 1.03 = 77.71 1.5X50D X
75 X 89 X1.7 9000 X 36
= 45.39
= 123G / M
Assume that 50D 17 / KG
Raw materials: 2 yuan weaving fee 1.3 yuan / M
Dyeing and finishing cost: 0. 9 yuan / m.
4.2 yuan of X shrinkage loss 14% = $4.79 + $0.30 calender
5.09 X 10% profit 5. 60 yuan / m. ( cost )
If there are spandex, such as: 75D + 40D = 105D
Therefore, the most accurate weighing methods: with a weight machine weight!!!!
Export cost accounting
Export total cost = G+Quota+A+F1 + ( 1+F x Ratel-V )
Export total cost = + + + + ( 1 + ) - x
The calculated results show:
Among them: G that exports the ex-factory price of goods or delivery price for export quota price, Quota, A for foreign trade companies to export agency fees, F1 is the factory ( warehouse ) to the port or airport freight, Ratel is the exchange rate, I is a sea or air insurance, F is the shipping, air freight, V export tax rebate.
Simulation : suppose there are a number of export to the United States in the clothing, the ex-factory price of 480000 yuan, the export quota total $18000 dollar, foreign trade companies of the agency fee of 2%, factory shipped to the port of shipment in the transportation fee is 1200 yuan, marine insurance fee of $118, shipping fee is $3500, the export tax rebate amount for 69743.59 yuan.
Solution: export total cost = G+Quota+F1 + ( I+F x Ratel+A-V )
= 480000+18000 x 8.28+1200 + ( 118+3500 ) x8.28+13204-69743.59
= 603657.41 ( RMB)
# 1: foreign trade company agent fee calculation, is an export contract price ( i.e. G+Quota+F1 + ( I+F ) x Ratel ) as the basis, and then multiplied by the agency fee.
# 2: export tax rebate amount is calculated: refund = sales amount (VAT invoices ) x export tax rebate rate = the ex-factory price / ( 1+0.17 ) xV. The state of various types of export rebate rate is different, in this case the clothing the refund rate is 17%.
Note: only the estimation results )
Warp x 36 x shrinkage / count was 840 x 16 = A
Weft density x 36 x transverse shrinkage / count was 840 x 16 = B
Square weight = ( A+B ) / 3 : 128 x 36 x 1.2 = 20 / 840 x 16 = 5.2oz
60 x 36 x 1.05 = 16 / 840 x 16 = 2.45oz
( 5.2+2.45 ) / 3 = 2.55g
Polyester fabric, polyester line density formula can be transformed into cotton counts, cases of 300D;
5247 / 300 = 17.49s ( 5247 is constant )
Polyester fabric, polyester line density formula can be transformed into cotton counts, cases of 300D;
5315 / 300 = 17.49s ( 5315 is constant )
Formula ( Note: only the estimation results )
The g = ( 5315 / 20) * [ ( 128 * 100 / 2.54) / 9000] = 148.8g = A
Zonal g = ( 5315 / 16) * [ ( 60 * 100 / 2.54) / 9000] = 87.2g = B
Square weight = ( A+B ) in square weight = 236g = 236 / 28.35 = 8.32oz
Simplify (inch by secret / imperial count ) * 23.25 = A
( British weft density / imperial count ) * 23.25 = B
I'll calculus again: 40s x 40s40d / 133 * 72 / 57 / 58 " grey price
Now the warp yarn price for 0.0235 yuan / g, the weft yarn is 0.029 yuan / g.
Warp amount = 133 / 40 * 58 * 0.65 = 125 grams
Weft consumption = 72 / 40 * 82 * 0.65 = 95 grams
Yarn price = 125 * 0.0235 = 2.9 yuan
Yarn price = 95 * 0.029 = 2.8 yuan
Weaving fee = 0.04 * 72 = 2.9 yuan
Grey price = 2.9+2.8+2.9 = 8.6 yuan / m, this is about the current market price!
I put this theory to explain!
If the weaving shrinkage was 1.10, loss of 1.02
The count is converted into a special wire ( 1000m yarn quality ) formula is 583 / 40
1 meters of cloth warp meters for
133 / 2.54 * ( 58 * 2.54) * 1.10 * 1.02 = 133 * 58 * 1.10 * 1.02
1 meters of cloth weft number of meters:
82 / 2.54 * 58 * 2.54 * 1.10 * 1.02 = 82 * 58 * 1.10 * 1.02
( note that here 82 is the machine width )
So 1 meters cloth warp amount equal to
133 * 58 * 1.10 * 1.02 * 583 / 40 / 1000 = 133 * 58 / 40 * ( 1.1 * 02 * 0.583)
= 133 * 58 / 40 * 0.654
This is the source of the formula!
General like no stretch is good as much as
40 x 40 / 133 x 72 / 58" ( specifications )
So it should be the 63 fabric"
So 1 meters of yarn weight can be estimated = ( 133+72 ) / 40 * 0.65 * 58 = 193g
