| FIG 2.1 SEQUENCE OF SPINNING |
2.1.1 Introduction of Spinning
Basically, spinning is the process of converting fibres into yarn and that is the absolute object of our chosen industry. In the textile process, the spinning units have a vital and basic role to produce any fabric or textile materials. For cotton natural fibres, ginning is the primary process from where fibres are cleaned from plants and ready for the spinning process. While in the spinning process, it is opened, cleaned, and mixed with each other according to product types and then convert from fibres to spun yarn. The yarn is carded or combed thus making them stronger, finer, and smoother. All things are possible with the machines like a set of blow-room machines, carding, draw-frame, lap former, comber, speed frame, ring frame, and winding are used to form the yarn.
2.1.2 Blowroom
2.1.2.1 Object of blow room
1. Opening:
(a) To open upwards the compressed bales of fibres.
(b) To brand the cotton fibre tuft every bit modestly every bit far every bit possible.
2. Cleaning:
To take dirt, dust, broken seeds, broken leaves, as well as other unusual materials from the fibre.
3. Mixing & Blending:
To brand the practised value of yarn as well as to decrease production terms mixing as well as blending is done.
4. Lap or flocks formation:
To transfer opened as well as cleaned fibre into canvas shape of definite width as well as length which is called lap or inward modern scheme straight feed to the carding machine into flocks form.
Blow room installations consist of a sequence of dissimilar machines to
carry out the higher upwards said operations. Moreover, Since the tuft size of cotton fibre becomes smaller as well as smaller, the required intensities of processing necessitate dissimilar machine configurations.

Fibre tuft is transported from pneumatic fibre feeding to feed rollers where the beater opens the fibre in small tufts then it comes into the chute. Further, there are feed plates and feed rollers which push the tuft to licker in. In licker-in, the tuft is open and helps to transfer the tuft to the cylinder evenly. The main process of parallelization, the opening of the tuft in individual fibre, and cleaning are done in the cylinder portion.
The rotational speed of the cylinder is very high and it is covered with carding cloth this helps to grab the fibre and then travel to the upper surface of the cylinder. Just above the licker-in, there are fixed bars and knives with suction to comb the fibre and remove the impurities respectively. On the top of the cylinder, there is a moving flat which also combs the fibres and parallelized fibre.
Moving forward, there are other fixed bars. Lastly, the fibre web is transferred to the offer and the remaining material which is not transferred is again revolved in the cylinder. At the bottom of the cylinder, there is a grid bar where unwanted heavy particles or impurities are eliminated. The passes through the calendaring roller then it is converted into a sliver in trumpet. The silver is stored in big cans with help of a coiler. There are other theories which also help to understand carding machine properly such as carding action, striping action etc.
Waste management - There are two output suction lines for waste Flat waste - Licker-in, cylinder and doffer. The waste from these suction lines is directly collected in the waste collection room. Now the collected waste is compressed with help of a bale compressor and bales are made. These bales are used in the next cycle.
Maintenance - General cleaning is done every day with the help of compressed air. Breakage (causes and remedies) Auto Levelling in Carding - In the spinning mill, the card is the effective start of the process, since the first intermediate product, the sliver, is produced here. A relatively high degree of evenness is required in this product. For various reasons, the card cannot always operate absolutely evenly, for example, owing to uneven material feed.
Spinning mills are therefore forced to use auto levelling equipment under highly varying circumstances. Different principles for auto levelling can be selected depending on the quality requirements and the operating conditions in the individual mill

2.1.7 SPEED FRAME
 |
| FIG 2.1.7 SPEED FRAME |
Technical Details
• Machine: Speedframe
• Company: LMW
• Model: LF4280
• No of machine:6
• Spindles: 200Spindels/Machine
Objectives:
• To convert drawn sliver into roving and to make it suitable for the ring frame process.
• To reduce the linear density of the sliver (weight per unit length).
• To insert a little amount of twist in the roving to improve its strength of it.
• To make a large conical package of roving suitable for a ring frame.
• To ensure easy and safe transportation of material by making large packages.
Passage of Speedframe
° The sliver obtained from the draw frame or after combing is used as feed material in a simplex or roving machine
° This sliver is put into the large can.
° This sliver, first of all, passes through separators.
° From this point, the sliver goes over the guide roller and then tensioning rollers.
° Now the slivers enter into the drafting zone, where it passes between drafting rollers. Generally, a draft of 6–15 drafts is employed for the fed sliver. The drafting system attenuates the sliver many times of its original length and reduces the weight per unit length of the sliver.
° The output material(roving) after drafting has very poor strength due to low linear density, therefore it needs a little amount of twist to hold the fibres together. The drafted strand of fibres passes through the flyer to provide this twist, Usually, 30-65 turns per meter are inserted into the roving.
° There are spindles in the flyers on which the twisted roving gets wound.
The Speedframe of maximum spindles is up to 280 for spinning both Cotton & MMF. The machine can be easily clubbed with Roving Transportation System by installing bobbin converters on any of the sides of the machine. The automatic Tension Control system ensures the uniform and consistent tension of the roving and thus delivers perfect roving packages with Supreme quality.

2.1.8 RING SPINNING LMW –LR9/AXL
 |
| FIG 2.1.8 RING SPINNING |
Machine: Ring Frame
Feed: Roving
Delivery: Yarn
Model:LMW-LR9/AXL
No of machine:15
Count:30s to 24s
Objects: o produce the required count of yarn from the supplied roving by drafting. Insert a sufficient amount of twist into the yarn. To wind the yarn onto the bobbin. To build the yarn bobbin package by the specific winding mechanism of the ring and traveller.
Passage - The first basic process is to provide a roving bobbin to the ring spinning through the creel. After the roving is placed on a creel it is pulled and directly passed through the drafting arrangement.
This drafting arrangement has an apron on the middle rollers to provide a better surface for the drafting. After passing through the drafting arrangement the formed yarn is passed through a lappet guide and then afterwards from the control ring. After that, the yarn is passed through the traveller so that twist can be imparted on the yarn. Finally, the yarn is wound onto the bobbin.
Detailed description - There are four zones in a ring frame which are as follows.
1. Creel zone
• The creel of the ring frame is a simple device that holds the roving.
• It is very important and evenly to avoid any roving brake.
• To facilitate proper unwinding the roving bobbin is held vertically.
• A typical bobbin holder is shown in the figure.
2. Drafting Zone
• The highest draft is given at the ring frame by comparing the whole spinning line.
• The drafting part is the most important part of the ring frame machine that directly influences the evenness and strength of the yarn.
• Most of the ring frame machines have the 3 over 3 roller drafting arrangement with the middle rollers covered with the aprons to provide a better surface for the drafting.
• The bottom rollers are steel fluted and driven positively. The top rollers are covered with synthetic rubber coating and driven by the frictional contact with the bottom rollers.
• For this purpose the top rollers are weighted by using spring, pneumatic or magnetic weighting with the help of a pendulum arm.
• A total draft of 15-40 and in some cases even up to 50 can be given at the ring frame
3. Twisting Zone
• Then the yarn passes through the lappet guide which works as a guide and controls the height of the balloon.
• After that the yarn passes through the traveller so that with the help of tension the twist can be imparted on the yarn. The traveller rotates on the ring, and one rotation of the traveller imparts one twist on the yarn.
• The bobbin is mounted on the spindle and is placed between the ring. It is positively driven by the spindle.
4. Package winding zone
• Just after the twisting by the traveller the yarn has to be wound on the cop.
• To wind properly on cop there should be a difference in surface speed between the spindle and the traveller.
• The traveller is not positively driven while it is dragged on the ring surface and carried along by yarn and wound on the cop.
5. Doffing of cop
• This is automation to take out the filled bobbin and place the empty bobbin.
• There is a doffing rail which changes the bobbin onto the spindle.
• It transports the newly filled bobbin to the winding department.
• Air pressure is used to hold the bobbin by arm to replace the bobbin on the spindle.
• It is the fastest way to change the bobbin while manually it is very time-consuming work.
