    Please also tell me the formula which help us to calculate the CLSP yarn should be used for such strength

  9. haider says

    i need a little help
    i need following strength specific fabrics
    16/s x 12/s / 96 x 48, 3/1, cotton, 63″width
    Tensile breaking strength (Strip Method)
    Warp: 265 kg or 2599.65 Newton
    Weft : 160 kg or 1569.60 Newton

    What CLSP or strength of yarn should be to make such a strong fabrics. Please reply me on my email: mianghulamhaider@gmail.com
