  2. Introduction: Cotton fiber is compressed in a bale of 200 to 250 kg. This highly compressed cotton fiber need to be open at first as a part of yarn manufacturing & there are 1.5 to 7% trash in cotton bale which is also needed to be removed before further processing. This process of opening & cleaning is known as blow-room process. And this process is done in a blow-room line. Rieter blow-room is a modern blow-room where uniform opening & cleaning are carried out.

  3. Fig: Bale Opener UNIfloc A11 A 11 UNIFLOC AUTOMATIC BALE OPENER - ECONOMICAL CLEANING STARTS WITH MICROTUFTS: This is the basis of the successful use of rieter’s unifloc A 11 automatic bale opener worldwide. The unifloc A 11 processes the fiber material gently and efficiently into microtufts, from which impurities can be removed very readily.

  4. Economy • • • 1.The UNIfloc is designed for output of up to 1 400 kg/h (carded sliver) 2. Bales are laid down over a length of 7.2 to 47.2 meters 3. Automatic bale profiling eliminates labor-intensive manual alignment of the bales. Fig: Double Tooth Quality 1. Opening bales into microtufts provides the basis for effective cleaning and dedusting by subsequent machines. 2. The double tooth profile ensures gentle extraction of the tufts irrespective of the direction of rotation of the take-off roller.

  5. Fig: UNIclean B12 B 12 UNIclean pre-cleaner - Efficient and reliable pre-cleaning: The uniclean B 12 pre-cleaner cleans the microtufts in the first cleaning stage immediately after the unifloc A 11.

  6. Economy 1. The UNIclean is designed for output of up to 1 400 kg/h (carded sliver). 2. Fiber yield with simultaneous efficient cleaning is up to 2% higher than on conventional units & energy-saving due to low air consumption. Quality •Pre-cleaning without nipping and the use of mote knives results in fiber-preserving cleaning. •The large dedusting surface ensures intensive dedusting even at high production performance. •Rapid assessment of high cleaning performance and low losses of good fibers by visual waste checks

  7. Fig: UNImix B72 B 72 / B 76 UNImix homogeneous mixer - Effective mixing in a minimum of space: The B 72 mixing machine guarantees homogeneous, intimate mixing of the bale feed in a minimum of space, even with unfavorable bale lay-down.

  8. Economy 1. The production volume of 800 kg/h (B 72) or 1 200 kg/h (B 76) results in an excellent price/performance ratio with comparably low space requirements. 2. The large storage capacity ensures regular feeding of the downstream blowroom machines and is the precondition for the production of quality yarn without personnel intervention. Quality The unique 3-point mixing principle with 8 mixing chambers produces a good, permanently homogeneous fiber mix. This is the precondition for consistently high yarn quality.

  9. Fig: UNIlend A81 The uniblend A 81 precision blender sets the highest standard for multi- component blending with an accuracy featuring less than 1% deviation. The uniblend A 81 enables four different carding lines to be supplied with different blends.

  10. Economy 1. Blending cottons of different origins enables material costs to be optimized. 2. Compared to drawframe blending, tuft blending on the uniblend enables a drawframe passage to be eliminated. 3. The UNIblend facilitates the precise recycling of waste. Quality 1. The homogeneous fiber blends from the UNIblend enable very high yarn quality to be achieved. 2. Homogeneous fabric appearance in the end product, even when using difficult dyes.

  11. Fig: Card C 60 C 60 high-performance card - The concept for outstanding performance With its unique geometry in the carding zone, the C 60 high- performance card provides one of the main building blocks for achieving financial success. With a working width of 1 500 mm, output by the C 60 card is up to 50% higher than on conventional models – and is combined with superior sliver quality.

  12. Economy 1. Maximum raw material utilization at carding output of up to 240 kg/h. 2. Compact design with small machine footprint, enabling the highest production volume per unit of surface area to be achieved. 3. The modular machine design reduces maintenance-related downtimes to a minimum. Quality 1. Efficient, gentle removal of trash particles facilitated by the higher centrifugal forces generated by the card geometry. 2. Gentle processing of man-made fibers and blends while meeting the highest quality targets.

  13. Fig: Card C 70 C 70 High-performance card - The card with the maximum active carding area: The C 70 high-performance card achieves excellent quality values at highest production. This is based on the well-proven 1.5 m working width and maximum active carding area.

  14. Economy 1. High production performance with top quality for ring yarn applications thanks to the maximal active carding area and optimized pre- and post-carding area. 2. Maximal card wire service life with constant sliver quality is guaranteed by the integrated grinding systems IGS Classic. Quality 1. Thanks to wider carding area combined with the precise flats guiding, even fine combed ring yarns can be economically produced with high quality. 2. Continuously good sliver quality is guaranteed by the integrated grinding systems IGS Classic.

  15. Conclusion: After the study on rieter blow-room line it is clear that, the rieter blow- room is a modern blow-room line. Where the uniform opening &cleaning are carried out. And it is so economical than others.
