# Yarn Consumption Calculation For Woven Material

• Share
Yarn consumption is measured from woven material specification. Yarn consumption agency warp weight calculation as well as weft weight calculation of woven fabric. There are unlike yarn consumption formula for woven material. In this article we will know well-nigh woven material specification in addition to then calculate weight of material. Woven Fabric Specification:
Woven cloth structure or specification as follows:

EPI X PPI
Fabric specification = ……………………………… X Fabric width
Warp count X Weft count

Or,

Warp count X Weft count
Fabric specification = ………………………………….. X Fabric width
EPI X PPI

For example,

32 ten xl
……………… x 50ʹʹ
lx 10 54

Fabric Weight Calculation inwards Running Length:
Calculate the weight of warp in addition to weft yarn inward kg to produce 2000m of the next cloth:

150 x 100
—————— 10 58”
50 x l

For warp weight calculation:

Here, EPI = 150
Total issue of ends = 150 ten 58

Length of each stop = 2000m + 2000m 10 0.03                      (warp bend% = 3%)
= 2060m

Total length of warp yarn = 150 ten 58 ten 2060 k

We go from the yarn numbering system,

L ten w
Ne = …………….
west ten fifty

L 10 w
=> due west = …………………..
Ne 10 l

150 x 58 ten 2060 ten 0.4536
= ……………………………………… kg + twenty% wastage of the full weight of warp
l ten 840 ten 0.9144

From the above organization a elementary formula is developed to calculate the weight of warp yarn inwards kg to produce a item length of a cloth as follows:

Weight of warp yarn in kg =

EPI x Fabric width inward inch x (Fabric length inward m + Fabric length inward m ten flexure%)
= ……………………………………………………….………………………………….. ten 0.0005905512
Ne warp

+ Wastage% of total weight of the warp (almost 20%)

For Weft weight calculation:

Here, PPI = 100
Total number of picks = 100 ten 39.37 x 2000

Length of each pick = (58” + 58” x 0.05) / 39.37             (weft crimp% = v%)
= one.547 one thousand

Total length of weft yarn = 100 x 39.37 x 2000 10 ane.547m

We get from the yarn numbering system,

L x w
Ne = …………….
W 10 l

L 10 w
=> W = …………………..
Ne x 50

100 10 39.37 x 2000 ten 1.547 10 0.4536
= …………………………………………………. kg + fifteen% wastage of the full weight of weft
50 10 840 x 0.9144

From the in a higher place organisation a unproblematic formula is developed to calculate also the weight of weft yarn in kg to create a particular length of a material equally follows:

Weight of weft yarn inwards kg =

PPI ten Fabric length in one thousand x (Fabric width inward inch + Fabric width inward inch ten crimp%)
= ……………………………………………………………..………………..…………. x 0.0005905512
Ne weft

+ Wastage% of total weight of the weft (nigh 15% although it depends on selvedge, loom type)

Similarly weight of the warp together with weft yarn inward pound (lb) tin live calculated by the next formula:

Weight of warp yarn inwards Ib. =

EPI x Fabric width inward inch ten (Fabric length in yds + Fabric length inwards yds 10 crease%)
= ………………………………………………………..……………………..………………..
Ne warp x 840

+ Wastage% of full weight of the warp (nigh 20%).

Weight of weft yarn in lb =

PPI x Fabric length inward yds 10 (Fabric width in inch + Fabric width in inch 10 flexure%)
= ……………………………………………………………………………..……………….
Ne weft ten 840

+ Wastage% of full weight of the weft (well-nigh 15%)

Problem:
Calculate the weight of warp together with weft yarn inward lb to produce 2500yds. of the next textile:

120 ten ninety
…………………. X 58”
sixteen 10 fourteen

The weight of warp and weft yarn in Ib. tin live calculated directly from the textile specification by using the to a higher place formula. It volition live very slowly together with it safety lot of times.

Solution:

Weight of warp yarn inward lb =

EPI ten Fabric width inwards inch ten (Fabric length in yds + Fabric length inward yds ten crease%)
= ……………………………………………………………………………..………………..
Ne warp ten 840

+ Wastage% of full weight of the warp

120 10 58 10 (2500 + 2500 ten 0.03)
= …………………………………………………. + 20%
16 x 840

= 1333.48 + 1333.48 ten 0.2
= 1333.48 + 266.696
= 1600.176lbs Or 725.84 kg (1600.176 ten 0.4536)

Weight of weft yarn in lb =

PPI x Fabric length inwards yds ten (Fabric width in inch + Fabric width in inch 10 crease%)
= ………………………………………………………………………..…………..…….
Ne weft 10 840

+ Wastage% of full weight of the weft (about 15%)

90 ten 2500 ten (58 + 58 ten 0.05)
= ………………………………………. + 15%
14 x 840

= 1165.eighteen + 1165.18 x 0.xv
= 1339.96 lbs Or 607.804 kg (1339.96 ten 0.4536)
