Problem

The document provides specifications for two fabric samples and calculates the weight of yarn used for warp and weft in each. For the first sample, with a warp count of 20 and weft count of 22, the warp yarn weight is calculated as 521.09 kg and the weft yarn weight is calculated as 457.73 kg. For the second sample, with a warp count of 18 and weft count of 16, the required warp yarn weight to produce 5000m of fabric is calculated as 725.28 kg and the required weft yarn weight is calculated as 766.49 kg.

Problem-4: Find out Wt.

of yarn in fabric (warp & weft), from the following


specification.
Warp count x Weft count
.………………………...... x Fabric width
          EPI x PPI
or,
20 x 22
.………… x 56”
60 x 58
Solution:
In 5000m fabric, wt of weft warp,
    60 x 56 x 5000 x 1.05
= ……………………………………… kg
  0.914 x 840 x 20 x 2.2046
= 521.09 kg (ANS)
In 5000m fabric, wt of weft,
   58 x 39.37 x 5000 x 56 x 1.05
= ……………………………………… Kg
     36 x 840 x 22 x 2.2046
= 457.73 kg (ANS)
Problem-5:
Find out the wt. of required warp & weft to produce 5000m fabric from the
following
specification.
18 x 16
.…….. x 58”
66 x 62
Solution:
                            66 x 58 x 5000 x 1.05 x 1.1
Required warp = ………………………..……..  =  725.28 kg (ANS)
                            0.9144 x 840 x 18 x 2.0246
                           62 x 39.37 x 5000 x 58 x 1.05 x 1.1
Required weft = ………………………...................….. = 766.49 kg (ANS)
                                36 x 840 x 16 x 2.2046
