Yarn Consumption for a Fabric (2024)

FAQs

How do you calculate yarn consumption in fabric? ›

The direct system is calculated with the formula N = (W/l) / (L/w). The indirect system uses the formula: N = (L/w) / (W/l). In these formulas, N is the yarn count, W is the weight of a sample of yarn, l is the unit of length, L is the length of the sample, and w is the unit of weight.

Weaving and knitting are the two main methods used to create fabrics from “yarn.” Devika Fibres manufactures Draw Textured Yarn, Air Textured Yarn and also supplies Polyester Yarn in India. Making fabric by arranging threads that pass in one direction with yarns at right angles to them is the process known as weaving.

Start with your desired total width and divide by the width of the fabric. Round up to the next whole number. This is how many widths of fabric you need. Then take the total desired length and multiply by the number of widths you just calculated.

Formula: (length x width x gauge) / 6 = yards needed. Length and width are in inches and gauge is in stitches per inch. The division by 6 is to convert the answer from square inches to yards. For example, if you'd like a scarf 48" long and 8" wide using a worsted weight yarn, (48 x 8 x 5) / 6 = 320 yards.

Apart from CAD and marker making method different respondents gives some mathematical method to calculate the fabric consumption. E.g. 26” is the chest width, then 26*2+ 26/2= 65” which includes the allowance of 3” then 68” will be the end to end width of the fabric.

By dividing the amount of thread by the seam length, we get the ratio of thread consumed. If we multiply this factor times the total length of seam, we can determine the total thread consumed for that seam. *Generally, 10% to 15% wastage of thread is added to the consumption derived.

Fabric consumption means the length or weight of fabrics needed for making a single piece of garment (apparel product). You know that for making apparel items, either you use knitted fabrics or woven fabrics.

Final answer: The fabric of the cotton saree is made by weaving cotton yarn which in turn is made by spinning thin cotton fiber.

How many sets of yarn are used to make a fabric? ›

From the passage, it can be concluded that two sets of yarns are used in weaving. The first one is called wrap which is tied lengthwise and the second one is the weft which is tied widthwise. Therefore, two sets of yarn (warp and weft) are used in weaving.

Average propensity to consume= Consumption/ Income. Was this answer helpful?

By dividing the amount of thread by the seam length, we get the ratio of thread consumed. If we multiply this factor times the total length of seam, we can determine the total thread consumed for that seam. *Generally, 10% to 15% wastage of thread is added to the consumption derived.

Equivalent Yarn Number (EYN) x 840 = Yield

These yields apply to both 100% polyester and poly/cotton blends. Below we will explain how the yield is determined. As you can see from the below table, the greater the number of plies, the lower the yield; however, the greater the plies, the stronger the yarn.

To calculate the amount of weft, you need to know warp width, the number of picks per inch, and the length of the weaving. I usually add ten percent to that number for weft take-up. (So for an 8" wide warp woven at 20 picks per inch for 65": 8" x 20 x 65" = 10,400" divided by 36"/yd = 288 yd plus 10% = 317 yd.

To figure out how much yarn you'll need for your project, find out the total amount of yardage needed (it should say on your pattern) and divide this by the amount of yardage in the ball of the yarn you are wishing to use as a substitute, which will tell you how many balls you will need to substitute the original.
