This document provides a spin plan for producing 12 tons per day of 32 Ne carded yarn for a weaving mill. The plan includes: 1) Calculations for the number of machines needed at each process step to achieve the production target within an 8 hour shift while accounting for typical waste percentages at each step. 2) Determinations of the number of machines required for winding (6), ring frames (54), simplex machines (7), drawing frames (3-4), carding machines (9) and blowroom lines (1). 3) Notes that the calculations were compiled and assembled by AKM Sahedujjaman, a textile engineering student, on April 8, 2018

Problem: Suggest a spin plan for the production of 12 tons per day of 32 Ne carded yarn for a
weaving mill.
Solution:
1. Winding:
(A) Total production/8 hrs. =
= 4000 kg
(B) Production /machine/8 hrs.
=
= kg
= 637.78 kg
(C) No. of machine required =
=
= 6. 27
For weaving 4-5
For knitting 3.5-4

2. 2. Ring:
Here, TM = 4
T.P.I = TM √
= 4√
= 22.62
(A) Total production/8 hrs. = Total weaving production/8hrs.+waste % of winding
= 4000+ kg
= 4040 kg
(B) Production/machine/8hrs.
= kg
= kg
= 74.60 kg
Simplex TM = 1.1
Count = 1.2
(C) No. of machine required =
= 54.16
3. Simplex:
TPI = TM√
= 1.1√
= 1.2
(A) Total production/8 hrs. = Total ring production/8hrs.+waste % of ring
= 4040 +
= 4120.8 kg
(B) Production/machine/8hrs.
= kg
=
= 575.99 kg
(C) No. of machine required =
4. Drawing-1:
(A) Total production/8 hrs. = Total simplex production/8hrs. +waste % of simplex

3. = 4120.8 +
= 4151.7 kg
(B) Production/machine/8hrs.
=
= kg
= 1314.19 kg
(C) No. of machine required =
= 3.16
5. Drawing-2:
(A) Total production/8 hrs. = Total drawing-2 production/8hrs. +waste % of drawing-2
= 4151.7 +
= 4168.30 kg
(B) Production/machine/8hrs.
=
=
= 131.14 kg
(C) No. of machine required =
= 3.17
6. Carding:
(A) Total production/8 hrs. = Total drawing-1production/8hrs. +waste % of drawing-1
= 4168.30 +
= 4184.97 kg

4. (B) Production/machine/8hrs.
=
=
= 451.76 kg
(C) No. of machine required =
= 9.26
7. Blow room:
(A) Total production/8 hrs. = Total carding production/8hrs. +waste % of carding
= 4184.97 +
= 4310.52 kg
In chute feed system production of 1 blow room line = 800 kg/ 1hrs.
Production / blow room / 8 hrs. = 800 8
= 5440 kg
No. of lines required =
= 0.79
