one. Raw material usage calculation

Definition: How many grams of weft and raw materials are required to weave a gray fabric .

1. Long fibers: After dosage (g/m) = total number of tracks × (D/9000) × 1.1

Weft usage (g/m) = cloth weft density × machine door width × (D/9000) × 1.1

Or = finished weft density × finished door width × (D/9000) × 1.1

Note: 1.1=1+10%, 10% is the shrinkage rate + loss, generally FDY takes 1.08, DTY takes 1.12

Add several concepts:

FDY: Full stretch body. Full name: FULL DRAW YARN. Synthetic filaments further produced by spin-drawing. The fiber is fully stretched and can be used directly in textile processing. (Generally called it filament).

DTY: stretch textured yarn, full name: DRAW TEXTURED YARN. It is made by using POY as raw yarn, and it is made by stretching and false twisting. There is often some flexibility and contraction. (Generally divided into network and no network, network means network node).

POY: pre-oriented silk, full name: PRE-ORIENTED YARN or PARTIALLY ORIENTED YARN. It refers to an incompletely drawn chemical fiber filament having a degree of orientation obtained by high-speed spinning between an unoriented filament and a drawn filament. Compared with unstretched wire, it has a certain degree of orientation, good stability, and is often used as a special wire for draw-twist textured yarn (DTY). (usually not used for weaving).

Example 1 Taffeta on the machine door width 168cm 17th ç­˜ 3 wear Grey cloth weft density 28/cm

(168 × 17# × 3 entries)

Raw material: 63DFDY × 63DFDY

Seeking: raw material usage

Solution: The amount used = 168 × 17 × 3 × 63/9000 × 1.08 = 64.77 g / m

The amount of weft used = 168 × 28 × 63/9000 × 1.08 = 35.56 g/m

That is, the theoretical Mick weight = 64.77 + 35.56 = 100 g/m

Example 2. 75DFDY+100DDTY Five Satin

12 #×5 into ×166 30 roots/cm

Seeking: raw material usage

Solution: The amount used = 12 × 5 × 166 × 75/9000 × 1.08 = 89.64 g / m

The amount of weft used = 30 × 166 × 100/9000 × 1.12 = 61.97 g/m

2. Short staples: The amount used = 0.664984 × (via dense / warp yarn) × width

The amount of weft used = 0.664984 × (weft density / weft thread count) × width

Note: Staple fiber can also be converted to long fiber, calculated using long fiber formula, D=5315/S

Example 1. 70D nylon FDY × 21S cotton 133 × 72 59”,

Solution: The amount used = 133 × 59 × 70/9000 × 1.08 = 65.91 g/m

The amount of weft used = 0.664984 × 72/21 × 59 = 131.4 g/m

Example 2. After: 70D Nylon DTY+30D Spandex

Latitude: 30S Cotton +40D Spandex

86 × 58 59”

Seeking: proportion of raw materials and proportion of raw materials

Solution: spandex has a draw ratio, generally 30D spandex is calculated as 10-13D, 40D is calculated as 15-18D, shrinkage ratio is generally desirable 3,

If 40/3=13.33, press 15-18D

The amount of nylon = 70 × 86 × 59/9000 × 1.12 = 44.2

The amount of spandex = 86 × 59 × 13/9000 × 1.1 = 8.06

Weft consumption cotton = 58 × 59 × 5315/30/9000 × 1.1 = 74.1

Weft spandex = 58 × 59 × 18/9000 × 1.1 = 7.53

Total = 44.2+8.06+74.1+7.53 = 133.89 g/m

Spandex ratio=(8.06+7.53)/133.89=11.64%

Cotton ratio = 74.1/133.89 = 55.36%

Nylon ratio = 44.2/133.89 = 33%

3. Twisting class: the amount used = total number of roots × D/9000 × 1.1 × (1 + shrinkage) × (1 + evaporate rate)

Weft usage = cloth weft density × upper machine door width × D/9000 × 1.1 × (1 + shrinkage rate) × (1 + evaporative shrinkage rate)

supplement:

3.1 Shrinkage

Calculation of contraction rate

1.Single species of raw materials: shrinkage (rebound) rate% = constant 0.0038 × number of turns squared (turns/mm) × times of multiples × raw material difference rate;

2 different raw materials: a raw material shrinkage × (1 + another raw material (D) second raw material (D) sum × difference in the difference between the two raw materials%)

3. Composite twisting: a 捻 to the same: contraction rate = initial contraction rate + complex shrinkage;

b 捻 to the contrary: contraction rate = initial contraction rate × (1-1 / total number of retanning) + complex shrinkage

4. Raw material difference rate

Rayon (Viscose, Copper Amide), Polyester 100%

Silk and Nylon (Nylon) 111%

Acetic acid rayon 123%

Silk 143%

Artificial cotton yarn and natural cotton yarn (blended yarn, pure spinning yarn) 120%

Gold, silver and aluminum 134%

Strip file

Every 5D below 120D is a file, rounded up, made out of threes and sevens

120D and above for every 10D, round off

Crush rate = 0.0038 × (T/mm) × (T/mm) × D

The multiple of D is based on 10D

40D-0.1 → 40/10-0.1 = 3.9

50D-0.2 → 50/10-0.2 = 4.8

60D-0.3

70D-0.4

...

120D-0.9 →120/10-0.9=11.1

130D and above increase by 0.8D for each additional 10D on the basis of 120D multiples

For example: 150D →11.1+3×0.8=13.5

Example 1. 75DFDY 22T/2S2Z, find: contraction rate

Solution: The contraction rate = 0.0038 × 2.2 × 2.2 × (75/10-0.5) = 12.87%

Example 2. 150DDTY 8T/2S2Z, find: contraction rate

Solution: Contraction rate = 0.0038 × 0.8 × 0.8 × (11.1 + 2.4) = 3.28%

3.2 Vaporization rate

Vapor shrinkage rate is less than 10T/cm, 5% for 10-20T/cm, and 6.5% for 20T/cm or higher

Example: 50D bright FDY 10T/2S2Z

Latitude: 75DDTY+40D Spandex 16T/2S2Z

On the machine 208 × 15# × 5 into 30 roots / cm

Seeking: raw material usage

Solution: the amount used = 208 × 15 × 5 × 50 × 1.08/9000 × [1 +0.0038 × 1 × (50/10-0.2)] × (1 + 5%) = 100.07

The amount of weft used = 208 × 30 × 1.12 × (75 + 18) / 9000 [1 + 0.0038 × 1.6 × 1.6 × (93/10-0.6)] (1 + 5%) = 82.18

Solution: raw material price 165/2.54 × 150 × 61/9000 × 1.08 = 71.33g/m

71.33 × 0.014 = 1 yuan/m

Note: Due to fierce competition, 170T polyester taffeta market is generally less than 170, only 165.

Previous price 166 × 17 × 2/1680 = 3.4 ie 4

4 ×0.03=0.12 yuan/m

Weaving price According to the calculation of 0.01 26 × 0.01 = 0.26 yuan / m

According to 0.015, 26 × 0.015 = 0.39 Yuan/m

Grey cloth price = 1+0.12+0.26=1.38 yuan/m

Or = 1+0.12+0.39=1.51 Yuan/m

Weft: 150DDTY 16T/2S2Z 1.38M/T

Grey cloth weft density 30/cm Grey cloth door width: 168cm

Solution: raw material price 11760 × 75/9000 × 1.08 = 105.84 × 1.56 = 1.651 yuan / m

168 × 30 × 150/9000 × 1.1 × (1 + 0.0038 × 1.6 × 1.6 × 13.5) (1 + 5%) = 109.76

109.76 × 1.38 = 1.515 Yuan/m

Previous price sizing 11760/1680 = 7 and

7 × 0.03 = 0.21 yuan/m

捻 Fee 109.76 ×16×0.0003=0.527 Yuan/m

Weaving price = 0.025 × 30 = 0.75 yuan/m

The grey fabric price is 1.651+1.515+0.527+0.75=4.44 yuan/m

Solution: raw material price by = 158 × 59 × 70/9000 × 1.08 = 78.3g/m

78.3 × 0.028 = 2.19 yuan/m

Weijia = 0.664984 × 76/32 × 59 × 3/4 = 68.3g/m

68.3 × 0.002 = 1.5 yuan/m

B=68.3/3=22.76 g/m

68/9000 ×76 ×59 ×1.1×1/4=9.32 g/m

(22.76+9.32) × 0.11=3.53 Yuan/m

Previous price 158 × 59/1680 = 5.55 or 6

6 × 0.6 = 0.36 Yuan/and

Weaving price 5.9/2.54 = 29.92 29.92/1.05=28.5 shuttle

28.5 × 0.13 = 3.71 Yuan/m

Grey cloth price = 2.19 + 1.5 + 3.53 + 0.36 + 3.71 = 11.29 yuan/m

Open fare = 11.29 × 1.05 = 11.85 Yuan/m

Note: According to the difference of the dyeing factories, the general dyeing cloth dyeing + finishing costs in the range of RMB 2.5/m -3.0/m. Of course does not include special finishing costs, such as washing, calendering, bronzing, etc.
