THE REASON WHY STILL WE CAN'T AVOID RING SPINNING SYSTEM

The main reasons why still ring spinning system is dominating the whole textile world.

Long before , say 2 decades are more open end spinning system was launched , everybody predicted that is the end point of ring spinning system. It survived , in fact Open End System was failed.

Why ?

A decade before , Airjet Spinning System developed by Murata , Japan , With the abnormal production increase , with the reduction of cone winding process and simplex(roving) process at any ways this project should become great success. But No. Even with recent update of Vortex Spinning , still the success was just only limited to 100% Viscose Yarn.

Even though with very smooth fabric surface , resistant to pilling still it cant beat fabric made by ring spinning system.

Why?

There are something "nature" made perfect , when you take about cloth quality - nature made ring spinning system as the perfect thing.

- Wide Range of Yarn Counts. From Ne 1 to Ne 300 - you can make with Ring Spinning System ( Eventhough with some practical difficulties.)

- With The natural twist flow , you will be rest assured of getting best strength possible.

- With even controllable drafting , the yarn created with better internal fibre structure , which is uniform and which makes the cloth very good hand feeling.

- Core yarn, Cover yarn, lycra , spandex and the list of special yarns goes for the time. Universally applicable and upgradable technology is Ring Spinning System.

- The raw materials of wide range or say almost all can be spun by using Ring and Traveller System.

- Drafting Speeds Can be Easily Controlled , which makes yarn unevenness better , however fibre length contributes as a major factor.

- When two entirely different fibres such as polyester and cotton blended - open end makes more harm to the yarn than doing good. Whereas Ring Spinning System is more flexible and more suitable for any kind of blending and any percent of blending.

- Yarns with SIRO process is considered one of the best quality because of its hand feeling , improved structure than doubled or single count. Which is not possible with any other spinning systems.

- Any Quantity can do very easily. , Sampling Process is very easy , fast , simple .

- Fine Yarns can be done very easily.

There are some more points to be discussed about this topic and hope time permits me in to do that next couple of weeks....

Catch you soon, please feel free to comment about this topic.

IS MAGNETIC PRINCIPLE HELPS ON RING TRAVELLER SYSTEM???

have u ever came across a new concept instead of present ring & traveller system??? ( forget about orbit / SU rings - all are in same generation.)

THE LIMITATION OF PRESENT RING & TRAVELLER SYSTEM

  1. Due to continous contact in between rings & travellers , we are unable to increase the speed of ring frame above certain limit.
  2. Many tried to reach 25000 rpm , but very less chance of success noticed due to more end breaks , higher worn-out of ring travellers , improper quality of the yarns etc., etc.,
  3. the most important limitation is - FRICTION between RINGS & TRAVELLERS.
How to avoid the friction between ring & traveller.

  • as of now , we can't avoid the friction , but we may try to reduce the friction , by using a better coating for both ring & travellers. or different profile of rings & travellers.
Why not we can have a better design - where there is no contact area in between rings & travellers ? If we able to achieve , no need of changing ring flange , no need of changing ring travellers , no limitation of speed , no much damage to the fibre strand , better yarn quality , better efficiency by avoiding traveller chnage & ring change...so many advantagous.........

Is it possible to do the same???//

If u ask me right now , the chance is REMOTE. But quite sometime before , i came across some article - the ring traveler system designed by using a magnetic principle....

We all know - Magnets has a character that opposite sides attract each other & the same sides distract each other.

on this case , If we have two magnets - One is Ring - X SIDE of a magnet & other is Ring travellers - Same X Side of a magnet ...............so it distract each other.............

Yarn is on the travellers and traveller is drived because of yarn pull ( as usual like now...)......

On this case , ring should be a electro magnet and traveller should be a permanent magnet.....

I hope this can be a possible if we have through practical research...............

Time will Say the Answer..! Isn't it?
