Textile Weaving Production Calculation Formula List

Textile Weaving Calculation & Useful Formulas: 

Weaving calculation is too much important to know for a textile engineer or textile related person to run a weaving factory perfectly. In the past, I have presented different calculation articles on the different parts of weaving such as winding calculation, warping calculation, sizing calculation, and loom production calculation. This article has presented all the formulas or laws needed to complete the mathematical problems of the weaving sector.

Winding Calculation Formula in Weaving:

1. Required time,

                 Quantity of yarn in-lb to be wound 
= …………………………………………………………………. 
       Number of drum× actual production in-lbs per hour 
 

Or,

      Amount of yarns in-lbs × count of yarn 
= …………………………………………………………. 
     No. of drum× actual production in hank 
 

Or,

                Amount of yarn in hank 
= ………………………………………………………… 
    No. of drums × actual production in hank 
 

2. Actual production in pounds,

    Calculated hank 
= ……………………… × efficiency% 
      Yarn count 
 

3. Actual production per hour in the pound,

     Actual production in hank
= ……………………………………………
           Count of yarn 
 

4. Actual production in the hank,

      Calculated yards 
= ………………………. × efficiency% 
              840 
 

5. Calculation production per hour in yards,

= ∏× diameter × speed in RPM 

Warping Calculation Formula in Weaving:

1. Required time in an hour,

    Length of warp to be produced in yards 
= …………………………………………………….. 
      Actual production per hour in yards 
 

2. Beam count or count of warp,

    Length of yarn in yards on the beam 
= ……………………………………………………. 
               840× weight in lbs 
 

Or,

    No. of ends × length of warp in yards 
= ………………………………………………….. 
                840× weight in lbs 
 

3. No. of ends in the warp,

    Yarn count× weight in lbs 
= ……………………………………….. 
      Warp length in hanks 
 

Or,

    Yarn count × weight in lbs × 840 
= ………………………………………………. 
           Length of warp in yds 
 

4. Length of warp,

   Weight of warp in lbs× yarn count × 840 
= ………………………………………………….. (Yds) 
                     No. of ends 
 

Or,

   Weight in lbs 
= ……………………….. 
   No. of ends 
 

Or,

    Weight of warp in lb× count of yarn 
= ………………………………………………. (Hank) 
                   No. of ends 
 

5. Weight of warp in-lbs,

    Warp length in yds× no. of ends 
= …………………………………………….. 
             Yarn count×840 
 

Or,

     Number of ends × length of warp in yds 
= ………………………………………………………. 
                     Count of yarn 
 

6. Total length of yarn in the warp,

    Number of ends× length of warp 
= ……………………………………………
                        840 
 

Sizing Calculation Formula in Weaving:

1. Total wt of size on the warp,

= Wt of sized warp – wt of unsized warp 
 

2. Total length of sized yarn,

= Total warp length × No. of ends 
 

3. Weight of sized warp in-lbs,

   Length of warp in yds × Number of ends 
= …………………………………………………………. 
                        Count×840 
 

4. Weight (wt) of size to be put on the warp,

= Size% required to be put on warp× Wt of unsized warp, 
 

5. Count of sized yarn,

    Warp length in yds × number of ends 
= …………………………………………………….. 
         Wt of sized warp in lbs× 840 
 

6. Count of sized yarn,

   Count of unsized yarn × 100 
= ………………………………………….. 
           Size% + 100 
 

7. Sizing efficiency,

= {Actual production/Calculated production) × 100%} 
 

8. Size% on the warp, 

          Wt of size 
= ……………………………. × 100% 
  Wt of unsized warp 
 

9. Weight of unsized warp in-lbs,

   Warp length in yards × No. of ends 
= …………………………………………………. 
               Yarn count ×840 

Weaving Loom Production Calculation Formula:

1. Loom production per hour in meter,

    No. of loom × PPM × Time × Efficiency 
= …………………………………………………….… 
                PPI × 39.37× 100 
 
2. Fabric weight,

= (warp weight+ weft weight)
