Fabric costing the latest version of the most detailed
Previously seen many articles on fabric cost accounting, some of the less thorough, and some a bit messy, and even some articles there is an error. I do according to their years of experience in textiles, summarized what material accounting knowledge. If not, and hope in time to contact me to give corrections.
We, as the textile fabric salesman, the general is the case, the guests gave a kind of cloth or to the detailed specifications, we need to analyze quotes. On fabric analysis, this article has a lot of very detailed, and I will not say any more here. Fabric cost accounting, the general idea is:
Raw material cost = cost + cost + weaving dyeing printing and finishing and rolling processing fee + inspection fees + packaging + in all aspects of tax loss
First, the raw material cost
Raw material cost = amount of X per meter yarn yarn price
How to calculate the amount of yarn per meter?
We divided all the fabric does not stretch the fabric, stretch fabric, lycra fabric to them out.
1. The fabric does not stretch
Guests to our large sample size are finished cloth or have dyed well, we need to revert to the fabric specifications of the finished product specifications.
Through to finished fabric density = density of X by the finished width / fabric width
Zonal finished fabric weft density = density X (1 - dyeing shrinkage)
Note: dyeing shrinkage, about 2-5% of cotton, polyester of 3-8%, 8-15% polyester, dyed fabric, the thinner the greater the shrinkage, machine cylinder dyeing dyeing shrinkage than the long drive to large, steaming hot finished fabric shrinkage requires smaller, the greater the shrinkage staining.
Formula: volume = warp yarn (warp density X width X0.65) / warp yarn that is: 128X63X0.65/21 = 249.6 克
= The amount of weft yarn (weft density X width X0.65) / weft yarn that is: 60X63X0.65/16 = 153.6 克
0.65 is a factor, a factor very rough, there are many factors affecting the size of this factor, such as weaving shrinkage, warp because of the tension elongation, loss, and so on.
Here's the yarn quantity per mibu does not mean that every Mick finished fabric weight, there is also a factor, usually with 0.88, we calculate the amount of yarn is 249.6 +153.6 = 403.2 g / m, finished weight is about 403.2X0.88 = 355 grams of rice, square weight is 355/1.5 (width) = 237g/m2, different fabrics vary greatly in this factor, the dyeing time, there are many factors that affect this factor, such as shrinkage , alkali reduction, pre-treatment, etc., often rely on experience to sum up this factor.
249.6X0.02 = 4.992 yuan per m
Similarly, assuming 16 of the cotton price is 18,000 yuan / ton, then the weft yarn cost
153.6X0.018 = 2.76 yuan per m
The specifications of the fabric material cost is 4.992 +2.76 = 7.75 yuan per meter.
Raw material prices can be in the major sites of textile materials textile market conditions which can be?? Rather special, for example, some yarn, a special blending ratio of the yarn, yarn for special purposes, not above the spot market, need to be spinning, and prices conventional yarn to be expensive, but also affect the cost and delivery time.
(2) stretch fabric
Conventional stretch fabric has a corresponding fabric, such as:
Stretch poplin cotton 40X40 +40 D/133X7257/58 finished fabric is 96X72 inches on the corresponding machine width 84 inches
Cotton stretch twill 16X16 +70 D/120X4048/50 finished fabric is 90X40 inches on the corresponding machine width 72 inches
Cotton stretch satin finished 32X32 +40 D/190X8057/58 inch of the fabric is 130X80 on the corresponding machine width 84 inches
Other than conventional stretch fabric width of the reduced rate calculated by this ratio, the average width is about 30% shrinkage, to restore the fabric specifications of the finished product specifications, and then there is no stretch of the fabric of yarn The formula to calculate the amount of yarn, raw material costs
3-way stretch fabric
Method is the same, we should also revert to the specifications of the finished fabric fabric on the machine specifications, then there is no way to calculate the elastic calculation.
Such as cotton lycra, the finished product specification is 32s / 2 +70 Dx32s / 2 +70 d density is 100X60 / inch, width is 46 inches, restore the fabric of the machine is the density of 65x46 size width is 72 inches, ( zonal reduction was 35%, was reduced by 23% to the general long car tie-dye), in accordance with the previous formula we can calculate the amount of yarn: (65 +46) x72x0.65/16 = 325g / m ( The latitude and longitude to put the warp and weft yarn density is the same sum), the amount per meter of yarn 325 grams.
Another example polyester lycra, a common product specifications 200d +40 dX200d +40 density is 118x80 / inch width is 57/58, reduced to gray on the machine specifications should Density is 82x56 (usually with a polyester lycra overflow tank dyeing, shrinkage is 30% to about latitude and longitude) on the machine width is 84 inches, 200d should be converted into count 5314/200 = 26.6, the amount of yarn in accordance with the formula to calculate the amount of yarn: (82 +56) x84x0.65/26.6 = 283g / m.
Other T / R Stretch, T / C Stretch, is the same reason, only the size of latitude and longitude to the different shrinkage, shrinkage rate data specific to consult with relevant production experience.
The yarn according to the amount of fabric, and then stained by taking into account the shrinkage, alkali reduction, among other factors, we can roughly calculate the finished weight, the theoretically calculated weight and actual weight varied widely, the general error of plus or minus 20 grams per meter, only as a reference.| Updated:2011.11.05 Source: Clicks:1874
