Yarn Weight - Fabric

Fabric

The following equation may be used to determine the weight of warp and weft required for a particular fabric:

  • Weight of warp = (0.65 x qty. of fabric (metres) x no. of warp ends) / count

If there are two colors in the warp, use the following equations:

  • Weight of color A (kg) = (0.65 x qty. of fabric (metres) x no. of warp ends of color A) / count of color A
  • Weight of color B (kg) = (0.65 x Qty. of fabric (metres) x no. of warp ends of color B) / count of color B

If the counts of two warps are the same:

  • Weight of color A (kg) = (total weight of warp reqd. x no. of ends of color A) / total no. of warp ends
  • Weight of color B (kg) = (total weight of warp reqd. x no. of ends of color B) / total no. of warp ends

or

  • Weight of color (B) = total weight of warp reqd. - weight of color A
  • Weight of weft = (0.6 x qty. of fabric (metres) x PPI x reed space) / count

If there are two colors in the weft:

  • Weight of color A (kg) = (0.6 x qty. of fabric (metres) x PPI of color A x reed space) / count of color A
  • Weight of color B (kg) = (0.6 x qty. of fabric (metres) x PPI of color B x reed space) / count of color B

or

  • Weight of color (B) = total weight of weft reqd. - weight of color A
  • Another formula
  1. Reed x width / 7000 = Ans
  2. Ans x quantity (mtr) / count = The weight required(Kg)

Famous quotes containing the word fabric:

    “It is not a piece of fine feminine Spitalfields silk—but is of the horrible texture of a fabric that should be woven of ships’ cables & hausers. A Polar wind blows through it, & birds of prey hover over it. Warn all gentle fastidious people from so much as peeping into the book—on risk of a lumbago & sciatics.”
    —Herman Melville (1819–1891)

    “The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
    —Willard Van Orman Quine (b. 1908)

    “Men may die, but the fabric of our free institutions remains unshaken.”
    —Chester A. Arthur (1829–1886)
