**Sewing Thread Consumption of Jute Sacking Bag:**

Normally five types of stitches are used in making a jute sacking bag.

- Hemming stitch
- Herakle stitch
- Overhead stitch
- Safety sewing
- Hand sewing

Above these five types, Hemming and Herakle are the most common two.

**How to Calculate Sewing Thread Consumption in Sacking Jute Bag**

**Determining Sewing Thread Length:**

The length of the sewing thread is determined by the following Equation,

Length of Sewing (Inch.) = Length of Sewing(Inch.) x Sewing factor x Ply Number

**Mathematical Problems and Solutions:**

**Problem:** In Making a sacking bag of 32’’ x 18’’, how much thread will be needed For making Herakle and mouth hemmed stitch at the top and bottom?

**Solution:
**The solution of the math will be divided into four sections, Such as

- Finding The Length of Herakle thread
- Determining the weight of this length of the thread of (1)
- Finding Length of Heming thread
- Determining the weight of this length of thread of (2)

**(A)** The Length of Herakle thread needed for Making a sacking bag of 32’’ x 18’’

= (Bag’s length + Bag’s width) x Sewing factor x Ply number for sewing thread

= (32 + 18 ) x 8 x 3 ply [as the thread of 8 ply]

= 50 x 8 x 3

= 1200 Inch.

= 1200 ÷ 36 yds.

= 33.33 yds.

**(B)** The Weight of sewing thread = Length of sewing thread (yds.) x { Yarn’s count(ply) ÷ 14400 }

= 33.33 x ( 8 ÷ 14400 )

= 0.0185 pounds.

= 0.296 Aounce. (ANS)

**(C)** Length of Hemming thread = Mouth’s length x 2 (Top & bottom) x Sewing factor x Ply Number

= 18 x 2 x 5.33 Single thread [As the Thread of 11 ply ]

= 191.88 Inch.

= 191.88 x 36

= 5.33

**(D)** The weight of hemming thread = Sewing thread’s length x (Count of sewing thread ÷ 14400)

= 5.33 x (11 ÷ 14400 )

= 0.0041 pounds

= 0.065 ounce

Now here the summation of all thread in need = B + D

= Herakle thread’s weight + Heming thread’s weight

= 0.296 + 0.065 Ounce

= 0.361 Ounce (ANS)
