Rotor spinning frame

Spinning is a process where yarn makes from cotton or something else by twisting though spinning frame machine. There are a few types of spinning machine are used around the world but we will discuss about most used machine like rotor spinning frame and ring spinning frame. Every modern machine has history which created by conventional machine. Modern machine is an upgrade version of conventional machine. Remove some unusual parts of machine & using some latest mechanical or electrical technology; speed up the machine and finally got the modern machine.

No Rotor Spinning frame No Ring Spinning frame
01 Rotor spinning frame is modern spinning system machine 01 Ring spinning frame is conventional spinning system machine
02 This machine makes yarn by high drafting from sliver. 02 This machine makes yarn by lower pressure than rotor spinning frame from roving.
03 The working speed of rotor spinning frame is faster than ring spinning frame. 03 The working speed of ring spinning frame is lower than ring spinning frame.
04 Usually rotor spinning frame produced lower count yarn. 04 This machine can produce from low count yarn to high count yarn.
05 Basically the raw material of this machine is low quality. Means low grade cotton. 05 Relatively this machine used high grade cotton to produce yarn.
06 Temperature and moisture of cotton should be controlled to produce yarn by rotor spinning frame. 06 No need to control temperature and moisture of cotton to produced yarn by ring spinning frame.
07 Room temperature should be controlled in 20 to 28 C on spinning room. 07 Its better if the room temperature controlled in 28 to 35 C.
08 Only one drafting system is available on this machine so there are now break draft in this machine. 08 Darting system is split in two divisions called main draft and break draft.
09 Twisting and winding process work separately in rotor spinning frame. 09 Twisting and winding process work with each other.
10 Production of rotor spinning frame is more than ring spinning frame. 10 Production of ring spinning frame is less than rotor spinning frame
11 Consumption of electricity is less than ring spinning frame. 11 Consumption of electricity is more than rotor spinning frame.
12 The ratio of breakage yarn is less than ring spinning frame. 12 The ratio of breakage yarn more than rotor spinning frame.
13 Production sound or noise is less than ring spinning frame. 13 Production sound or noise of the machine is more than ring rotor spinning frame.
14 The produced yarn package large. 14 The produced yarn package is small.
15 A few labor or technician can produce or maintain rotor spinning machine. 15 Ring spinning machine required more than ring spinning frame machine.
16 Rotor spinning frame produced balanced yarn. 16 Ring spinning frame produced less balanced yarn.
17 Trash less cotton is perfect for make yarn balanced so always used cotton should less trash cotton. 17 Comparability this machine can produce yarn from maximum amount of trash full cotton.

Technical specification of modern ring frame

About Ring spinning frame:

Spinning is the final step of yearn manufacturing process. The working procedure of ring spinning frame is taking the roving comes from simplex and produced yarn by reducing the weight of unit length. Ring is attached around bobbin. The traveler rolling on ring and enfold the yarn on bobbin. Ring spinning frame plays the vital role to spinning the yarn so it is called Ring spinning frame. Ring spinning frame’s production system is conventional.

Technical specification of modern ring frame

Ring frame is only one machine which can produce yarn by any kind of fiber. Basically the working system of ring spinning frame is easy and the cost of machine is a little cheap. It is easy to separate the bobbin from ring and easy to carry. but a few problem also reduce its popularity like, working speed, conventional system, large amount of electricity consumption.  please follow the link to know more about rotor spinning frame and ring spinning frame.

  1. What is Clothing?

Clothing is a vast ward which is come from cloth; simply we know cloth means fabric but if we looking toward to know abut clothing then “clothing is a technique of garments manufacturing with fabric by using different design”. We need warp and weft yearns to weave a fabric as like as to make a garment we need fabric with many accessories. In one sentence “every technique of related with garments manufacturing process are called clothing”.

  1. What is spinning?

Spinning is process in textile where manufacturing yarn by using one or various textile fiber. Yarn is made by twisting and it’s should be minimum length as it can use in textile to make it garment. So we defined the spinning as a minimum length and strength full yarn making process.

  1. What is trash?

In a single sentence trash is no lint material in the cotton fiber. Various foreign materials also present in cotton also called trash like leaf, dust; break seed, micro fiber, and neaps etc. trash create different kind of problem during spinning process.

  1. Specification of any cotton fiber

Fiber length                             : 1.5

Amount of trash                       : 2.5%

Micromeres value                    : 3%

Strength                                   : 90,000 P.S.I.

  1. The quality of cotton fiber depends on.
  • Length of fiber
  • Strength of fiber
  • Color of fiber
  • Matured of fiber
  • Amount of trash
  • Flexibility of fiber
  • Sophistication of fiber
  1. What is ginning?

After cultivating cotton from field, its need to separate the fiber and seed. Seed and cotton fiber separating system is called ginning process.

  1. What is Lint?

Lint is long and suitable fiber for spinning which is separate with seed by ginning process. Lint is used to make yarn.

  1. What is linter?

After complete ginning process; some micro yarn are sticky with seed which is not directly used to make yarn is called linter.

  1. What is the amount of strength of a fiber is generate into yarn?

Generally 80% strength of fiber is generating into the yarn.

 

  1. Acceptable amount of cotton moisture?

Acceptable amount of moisture of cotton fiber is start from 6.5 to 8.5.

This article is about What is carding and classification of carding machine? Trash and impurities full fiber is not able to proper spinning to build the basic construction of yearn. So it’s should be remove by different process, which is include in blow-room one process after another process. Removing Trash is process is started from first line of blow room and the second step of Trash removing process are called carding process. Carding process is one of them, which are played the vital role to remove maximum of trash from fiber. To make yearn it’s important to make a sliver after removing trash.

The basic fundamental of carding machine is removing trash and make long sliver to build the basic construction of spinning yearn.

 

 

Objects of carding machine

  • Take the lap from blow room and make it small unit and make them align.
  • After blow room process, make sure the fiber is full free of dust, short fiber, break seed and unnecessary things.
  • Extra and unnecessary short and hairy fiber completely removed from sliver.
  • Made by the Immature fiber is called napes are make free by carding process.
  • Fiber could be blending and mixing if necessary by this process.
  • Make the fiber prepared for next process by make them equal and same distance among every fiber.

 

 

Different types of carding machine:

  • Roller and clearer card
  • Stationary flat card
  • Revolving flat card

 

 

 

In the era of modern science the carding machine also discovered new and easy to use by depend on setting and setup the cylinder and take in. Out modern carding machine gives us extra care about the fiber and make them more smooth and useable. The another different design and style carding machines are

  • Dual carding machine
  • Mono or single carding machine
  • Tandom carding machine
  • Schubert & sulzer super carding machine
