ABSTRACT
In the modern age of the industry, the textile industry played a key role in the textile industry. The innovation of spinning textile industry specialization is a model of other sectors of modern technology, and rapidly increases production at medium time intervals that are generally accepted, and the main export sector and dominance of the dominant. The invention of the high modernization machine and the final technology of the modern age robot system has actually replaced the area radiation system while maintaining time and increasing productivity, reducing general principles. Very efficient rotating technology cavities have changed common rotation technology through innovative rotating machines. The high-efficiency chrome king machine was considered the most efficient and very innovative technology in the rotation era. This chapter of this book has discussed the use of innovative machinery and robotics in spinning technology to save time, reduce yarn defects and improve cotton yarn spinning quality.

INTRODUCTION
When processing materials, different types of machines are required, such as opening machines, cleaning machines and mixing machines. Different processing intensities are also required as the beam is constantly getting smaller as it moves from step to step. Therefore, it is ideal to rough clean the machine after the bale opener. For example, inappropriate at the end of a line. So there is no universal machine, a blow shop line is a series of different machines arranged in series and connected by transport channels. In the line, each machine offers optimum performance. Other locations give less than optimal performance. It can also benefit from different modes of transport, feeding, handling, cleaning, etc. from one machine to another along the line. The Blowing Room consists of several machines used in succession to open and clean the cotton fibers. As the fluff becomes smaller and smaller, the required processing intensity requires different machine configurations.
Importance of Blow Room
The blow room is the first working area for short staple spinning. Enormous first and pre-mechanical loads are applied to the fibers in this area. The Blow Room employs a technique involving the rotation of short staples.

RECENT DEVELOPMENT IN BLOW ROOM
The current trend in spinning mills is to replace manual bale openers with automatic bale openers. Automatic bale openers produce smaller batches, improving the opening and cleaning efficiency of subsequent machines. The manual baling process relies more on the integrity and efficiency of the operator, and the bundles supplied to the bale openers vary in size.
1. The Rieter UNIfloc A11 uses a single pull roller called a deflection roller. Automatic bale openers gradually level the bales by measuring the profile of the stacked material at regular intervals.
2. The Trützschler BLENDOMAT BOA is equipped with two counter-rotating plugging rollers. Three different batches of cotton/blend can be processed simultaneously, which can be fed to three separate wash lines.
3. The automatic bale opener Marzoli Super Blender B12SB has two draw rollers with 254 blades on each roller to ensure small flocks. The automatic bale opener can handle 4 different mixes. The declared productivity at a working width of 2250 mm is 1600 kg/h.
4. Automatic Drawer The Lakshmi LA 17/LA 28 is equipped with a double draw roller. Picking roller grids are selected according to the required bundle size.
Small Blowing Line:
Using 3 or 4 drums (Trützschler CVT4 Cleaner) in series on one machine instead of 2 or 4 machines in series ensures the same cleaning. In this way, modern blow shop lines are shorter without sacrificing quality.
CARD
Carding is a second spinning process that transforms the feed material (overlap) into uniform strands of fibers called “slivers”. A high-quality carding of cotton is very important because the quality of the yarn is highly dependent on it. The nep rate of the yarn depends on the quality of the carding process. “Cards are said to be the heart of spinning.” In the carding process, the material passes through a carding machine. The fibers are parallel to each other. During this operation, the fibers are entangled and can remove all kinds of impurities present on the cotton.
Carding, stripping and lifting operations occur during carding operations. A continuous and uniform parallel fiber sliver is thus obtained that is substantially free of impurities after carding.
OBJECTIVE OF CARD
Here are the main goals of the carding process:
• Full opening of the cotton bundle (individual fibers of the cotton bundle are opened during the carding process).
• Make the fibers parallel to each other along the length of the tape. Removes impurities present on the surface as much as possible. (To achieve higher cleanliness. Today’s cards achieve 90-95% cleanliness. So the overall cleanliness of the blower and card chamber is 95-99%. Card tape still contains 0.03-0.05% contaminants.
• For removal of very short fibers that cannot be spun yarn.
• Remove any neps present in the material from previous processes such as blowing and mixing
- For fiber blendingand achieving fiber blending.
• To finally turn the cotton web into a uniform ribbon

Grinding and Its Importance:
There are three areas in any carding machine. These are:
1. Opening and Cleaning area
2. Carding area
3. Sliver formation
The main segments of carding machine are covered by card clothing. These metal cloth with sharp wire. The wire looses its sharpness due to metal to metal or metal to fiber friction. That’s why it needs resharpening
CONCLUSION
Rieter blow chamber is an important part of yarn production. This is the first m/s going into the card m/s. It follows some linear textile processing patterns. It is very important to follow these lines in order to complete the treatment correctly.
Carding is the process of making fibers into parallel alloys. This is required for all staple fibers. Otherwise, fine threads cannot be produced. The remaining impurities must be removed before the raw material is turned into yarn. The fibers must be at different angles and rotate in a straight line. Cards are coarse-spun mills, well-combed ones are semi-spun. It shows the deep meaning of carding for final opening work.
