Cotton Spinning Procedure Overview | Curt Staple Spinning - Blowroom To Ringframe Procedure Sequence
Tuesday, 8 July 2014
Edit
Cotton spinning has straight off completed a milestone alongside modern machines where processing fourth dimension together with machines alongside adult man ability requirement has been reduced. Most of the spinning mills are straight off established alongside modern machines but the basic procedures of spinning are followed perfectly.
Cotton is the most usable natural vegetable fiber which covers almost 60% of total fiber requirement inward textile sector. After getting cotton wool fibers from state it should go processed alongside ginning machine to dissever seeds from raw cotton. Little total seed must rest alongside cotton wool fiber which is considered equally trash materials of cotton wool where other particles likewise remain. We larn yarn from cotton wool fiber alongside many of the spinning physical care for together with finally at that topographic point almost 70-72% yarns nosotros tin send away collect together with rests are removed equally wastage. If nosotros brand physical care for for 1 kg raw cotton wool together with thus nosotros volition larn 750-780 grams cotton wool yarn. Cotton fibers are to a greater extent than oftentimes than non processed to spin for making ii types of yarn. Carded yarn together with Combed yarn. Now or thus other technique likewise has been introduced equally rotor spinning to brand opened upwards terminate cotton wool yarns.
Process sequence together with their brief description straight off mentioning below for amend agreement of cotton wool yarn spinning.
Bale management:
Bale administration tin send away go defined equally the judicious pick of bale orcotton fibre inward lodge to achive acceptable economical spinning surgical operation together with consistent yarn quality. Bale administration is essential for perfect together with homogeneous blending. Bale administration also
applicable for hossiery physical care for together with rotor. Collect samples from 100% bale. The samples are tested inward HVI . Then decide all the parameter of fiber colleted. . Quality assurance subdivision i time to a greater extent than check
whether these bales fulfill the requirements. Then all the bales are arranged nether the
Bale Plucker.
Blow Room:
The cotton wool comes inward compact bale form, which are non suitable for processing. So it possess got to go opened, cleaned together with made gratuitous of contamination earlier processing. To obtain consistent parameters throughout the process, the cotton wool possess got to go mixed uniformly. All these tasks are carried out inward the blow room. At kickoff the bale accommodate nether the bale plucker. Bale plucker raw cotton wool inward lump sort out together with sends these to multimixer through air transportation for condensor. After the heavy particles being
removed, the cotton wool is blended together with mixed inward the 4 chamber. Then it is taken for fine opener & cleaning. Then the fabric sent to the carding machine for farther processing via chute feed.
Carding:
The carding machine mainly removes the Neps, curt fibers together with remaining impurities inward the cotton wool fiber together with forms carded sliver. Mainly impurities are removed at the taker inward together with the neps together with curt fibers are removed past times activeness betwixt the cylinder together with flat. It is called the midpoint of cotton wool spinning because the lineament of a cotton wool spinning factory is greatly subject upon the surgical operation of the carding machine. The carte du jour slivers are delivered inward carte du jour sliver cans which are then‐feed to the breaker drawing frame.
Breaker/ Pre‐comb Draw Frame:
In the breaker describe frame half dozen carded sliver cans are feed at a fourth dimension together with are drafted to i drawn sliver. By this, the fibers inward the sliver becomes to a greater extent than oriented, parallelized together with the irregularity of the strand decreases. Produced drawn sliver cans are together with thus either fed to the finisher if it is carte du jour physical care for or feed to the lap one-time if it is combed process.
Lap Former:
For combing, the fabric possess got to go presented to the comber machine is a lap form. So to convert the slivers into mini laps, the lap one-time is used. Here 26 drawn sliver cans are doubled together with drafted together to sort out lap. The lap is together with thus feed to the comber machine.
Comber:
The comber machine mainly combs out the lap together with removes whatsoever variety of neps, curt fiber or other impurities nowadays inward it. It likewise parallelizes the strand to the maximum degree. As a upshot the yarn produced from this sliver possesses amend lineament together with aesthetic properties. The produced combed sliver is together with thus feed to the finisher / postcomb drawing machine.
Finisher / Post‐comb Drawing Frame:
The finisher is the in conclusion machine where the irregularities inward the strand tin send away go modified easily together with whatsoever error later on this volition operate on to the yarn. So this machine is of cracking importance. That is why this machine is equipped alongside an auto‐leveler. The auto‐leveler continuously scans the incoming slivers together with increases or decreases he draft inward the drafting zone to minimize whatsoever thick or sparse place. half dozen breaker or comber sliver cans are feed together. This machine is monitored continuously really carefully. The produced finisher sliver cans are together with thus feed to the simplex machine.
Simplex:
In the band frame, if the yarn is produced direct sort out sliver, together with thus a really high total of draft volition go necessary, which volition go un‐manageable. That is why the fabric is gradually drafted together with an intermediate strand named roving is produced. Influenza A virus subtype H5N1 slight total of twist is likewise inserted inward the roving to ensure breakage gratuitous winding together with unwinding of it on the roving bobbin. Then the ravings are feed to the band frame.
Ring Frame:
In the band frame, finally the yarn is produced past times drafting the roving. Here twist is inserted inward the yarn to obtain required strength. Twist is inserted past times agency of band traveler. The break of turns that the spindle rotates at i revolution of the forepart roller is the break of twist that are inserted on the unit of measurement length of yarn. Then the yarn are injure on band bobbins. When the bobbins are full, they are doffed from the machine automatically mechanism.
Auto Coner:
The auto coner is a machine for automatic winding of yarn on cross injure packages. The yarn is injure on newspaper cones. It represents an autonomous, compact winding machine, which is equipped alongside a splicer together with electronic yarn clearer inward each winding unit. The EYC continuous scans the yarn for faults using either capacitative or optical regulation or both. When a error is found together with thus it cuts it out. Then a upper together with lower arm catches the yarn together with brings the ii ends to the splicer where they are joined together. The joining is done past times agency of compressed air. Thus the finished cones are produced which are together with thus estrus laid upwards together with packed inward required sort out of packaging.
Heat Setting Machine:
Heat setting is mainly done to stabilize the twist inward the twisted yarn, cut down hairiness together with increment the wet content inward the yarn packages. The yarn cones are arranged on trolleys. Maximum half dozen trolleys tin send away go fed to the machine. After that the machine door is closed. Then vacuum is created within the machine together with H2O at 60°C is sprayed within the chamber. Due to negative pressure, the H2O becomes steam. There the yarn packages are estrus laid upwards inward the steam for 45 min
Bale administration tin send away go defined equally the judicious pick of bale orcotton fibre inward lodge to achive acceptable economical spinning surgical operation together with consistent yarn quality.
