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:

    “We all participate in weaving the social fabric; we should therefore all participate in patching the fabric when it develops holes—mismatches between old expectations and current realities.”
    —Anne C. Weisberg (20th century)

    “The lore of our fathers is a fabric of sentences. In our hands it develops and changes, through more or less arbitrary and deliberate revisions and additions of our own, more or less directly occasioned by the continuing stimulation of our sense organs. It is a pale gray lore, black with fact and white with convention. But I have found no substantial reasons for concluding that there are any quite black threads in it, or any white ones.”
    —Willard Van Orman Quine (b. 1908)

    “Counsel woven into the fabric of real life is wisdom.”
    —Walter Benjamin (1892–1940)
