Definition of Rotor Yarn | Characteristics of Rotor Yarn | Rotor Spinning Process
What is Rotor Yarn?
In textile spinning sector, open ended spinning or break spinning is considered as rotor spinning. Here, total process flow chart is less than combed yarn as well as carded yarn. One important point should be pointed out here that, roving formation in simplex machine is not needed in rotor spinning where drawn slivers are fed to the machine directly.

Medium to low quality yarns are produced here which are used for making dungaree, denim, chino, and twill as well as any heavy fabric. Production rate of open end spinning process is higher than ring spinning process where coarse yarns are made within a range of 5 to 40 cotton count. Rotor spinning is too much popular in use because of the higher production rate and less wastage percentage as well as highly usable in denim to make blue jeans.
Properties of Rotor Yarn:
Important properties of rotor yarn have mentioned in the below:
- Imperfection index is lower in case of rotor yarn.
- Less amount of power needed during rotor yarn manufacturing.
- Stiffness is higher in rotor yarn.
- Breaking strength is lower in rotor yarn.
- Mass irregularity is better here.
- Co-efficient of variation (CV %) of strength is higher here.
- It has higher abrasion resistance.
- Possibility of producing rotor yarn count ranges from 3 to 60Ne.
- Energy consumption with productivity is lower in case of rotor yarn production.
- Volume is greater here than ring spinning.
Flow Chart of Rotor Yarn Manufacturing Process:
The main flow chart of rotor yarn manufacturing have presented in the following.
Input | Process / Machine Used | Output |
Fibre or Bale management | Blow room | Lap |
Lap | Carding machine | Carded sliver |
Carded sliver | Draw frame | Drawn sliver |
Drawn sliver | Rotor spinning | Rotor yarn |
