How to Calculate Yarn Production in Spinning Mill Per Shift of 8 Hours

1. Given, Yarn’s Number =20. TPI=? …
2. Given that, Spindle speed = 9000r.pm. Front roller speed = 203. …
3. Turns per inch = √ 36 x 4.5 =27.0. Front roller delivery per minute = 1000 / 27 =370”(Inch)

What is the formula of TPI?

of twists in one inch of yarn (or roving) is known as TPI (twists per inch). P = πDN x 60 x 16 x 8 x η [oz/shift/spindle] TPI x 36 840 x ct. the value πDN can also be mentioned as delivery speed.

What is OPS in spinning?

Ounces Per Spindle (OPS) is used for measuring/monitoring capacity and efficiency of spinning plant. It represents ounces of yarn produced per spindle worked and it varies with count i.e. the finer the count, lesser the standard OPS.

How do you calculate winding length for a ring frame?

The recommendation of Chase length for better performance in ring frame is Ring Diameter plus 15% to 20%. Winding length is called as yarn delivered per chase. ie, yarn wound on the cop for one stroke of the ring rail movement.

What is TPI and TM?

The number of turns of twist in one inch of yarn. TM-twist multiple is derived from the TPI and the yarn count and describes the relative twist level in a yarn (TPI = TMvNe).

How do you calculate average in spinning mills?

Calculate separately the length of the yarn of each count in kilometers by simply dividing the given weight in grams by its count number. Then add the length of all the yarns together. Also, add the weight of all the yarns together.
