Mr.Sivakumar.M.R. Senior Manager ~ Maintenance, Patspin India Limited, Ponneri, Udumalpet, Tamilnadu The spinning of yarn in rng frames is controled by three units - Ring, Traveller and spindle. The theory of ring and Traveller I the retardation of he Traveller relating to spindle and bobbin diameter increase. In ring frames the function of the spindles maraly to rotatathe bobbin and therety the yarn and provideforce tomovethe Traveller around the ring The Travellers the important media imparting twist and winding. The principle ofthe Travelers toimparta drag effect so thatthe yarn can be wound and atthe same time twisted, Hence, the Traveller lags behind and gives the efecto drag. The forces acting during the winding ae Gentrtugal orce ote Traveler Friction between ring and Travaler Centrifugal force afte yarn Tension of theyarm during its passage through the appet guide Tension of theyarn during its passage through the Traveller Tansian ofthe yarn when winding on thebobbin. Too Lower winding engthcauses fr balloon collapse, Traveller loading and breaks. Chase length is a distance of cop building by changing of chase length in spinning, Traveller contac area wile varying and winding cols distance wil also be varying. Too higher chase length causes for wider wincing cals, lesser cop cantantand lesser Traveler ie. Too lower chase length cause for narrow winding cols and higher cop content. Performance of ing Travellers: For easy unwinding of yarn from the cops at subsequent process, a ring frame each layer ofcop build isin the form of cone. Duet this the Traveller wil have aitferent speeds atthe base andthe tip. In comparison with the constant speed ofthe spindle, the Travllarhas a changing speed ditference of 0.77 to 1.41% for every chase, Similarly, theangleof pul ofthe Traveller by thespinning yam andthe friction generated by Traveller on the ring, will aso continuously change. Asallthe varying factors will have it impact onthe feo the Traveller andthe quality of yarn, for getting better Traveler life and yarn quality, the Cop diameter sould be equal toring diameter minus 1.Sto 2.00 MMand the chase lengt should be equalto ring diameter plus 4.000 6.00MM Mr. Vikram C.Patil,Asst.Manager-Maintenance, Vitthal Corporation Limited, Mahisgaon, Maharastra During cop building chase and winding length, ring ral speed & number of colls(CM shouldbe selected in such away that maximum cop conten is achieve, at thesame time, ing Traveller performance, should not get affected dueto various tensionalforeas xeballooning The difference of rotational speeds ofthe balloon, Traveller and the spindle allows he yarn to be wound on the empty tube. Traveler dogs the job of regulating spinning tension and it shouldbe high enough to have stable balloon, Chase length isthe distance between top and bottom most position of rng rail in one stroke of the cam movement ‘Wining length isthe ring rail speed i. the yarn delivered or ength of yarn wound per one chase, in order to achieve the above, keeping the chase length constant, if the yarn delivered per chase-winding length is increased the ring rail speed will be reduced to accommodate more yer witin the given chase and thereby the distance between the cols wil be reduced and results in compact bobbin. Formation of compact bobbin increases the diameter at every effective ‘winding on paint, which results in reduction of yarn winding tension, wich leads for beter Traveller performance Too higher the chase length and lower winding length — leads to higher winding tension, wider winding cols, lesser Traveller Ifeand lesser cap content. Too lower the chase length and higher winding length — leads to narrow winding eolsand higher cop content Recommended guidelines for better performance of Ring Traveller: CChase length should ve ring diameter in MM + 10t0 12%. CChase length and winding length ring rll speed shouldbe setin such away that winding and binding col ratio shouldbe2to 2.5: 1. Mr.8.Kather Mohideen, Maintenance Incharge, Sri Thiruvettai Ayyanar Spinners Pvt Limited, Kappalur, Tamilnadu Effects on the performance of Ring Travellers by changing winding length and chase length in spinning ‘Normally, If the winding length increases the ring rail speed gets slow, If the winding length decreases the ring rail speed gets increased, If the ring rail speed inoreased the Traveler tension also slightly increased, which causes higher end breakage rate when comparing tolower ring rail speed, Gap between tering and cop dereasas angi of pul also varies, the gaps ighn longa chase length, when comparad to shorter chs length, longer chase length gies morsiresstothe Travel, when comparing wthlower chase length Chase lngth must ese as rng ameter «406 UM, Ifthe chase length decreases, un-winding problem oacurs in futher process and cop retin also increased The road to success and the road to failure are almost exactly the same¢—ILRT Replies from the Readers Mr.K. Thangamariappan, Maintenance Incharge, Sri Jayajothi& Co Pvt Ltd, Rajapalayam, Tamilnadu By increasing the chase length, the cistance traveled by the ring rail will ncrease, More yarn can be accommodated. Ifthe yarn delivered per chase is ‘unaltered, the cistance between the yam coils wil be increased and the effective diameter at each winding on point wil be reduced, Reduction of effective iameter at each winding on point, vil lead to reduction of spinning anole, thereby yarn tensions increased Increase in yarn tension wil tect the performance of the Traveller. yarn delivery per chase is increased when chase length is increased. Yarn delivery per cchasels decreased when chase lengths reduced. Butin old machines, we have todo thy changing the wheels which normally is being ignored, Keeping the chase lenath constant, ifthe yarn delivery ner chase-winding lenat is increased; the rng rail speed wl be reduced to accommodate more yam \ithin the gven chase and thereby the distance between the cols wil reduce and results in compact bobbin. Formation of compact bobbin increases the diameter at every effective winding on point wich results reduction of yarn winding tension leads to better performance of the Travel Ith yan delivery per chases reduced, the ring ral speed wil beineressed toaccommadatelass yarn within the given chaseand thera by the distance between tha cots wil increase and results in less compactbobbin. Less compact bobbin means, the ciameter at every winding on point \will lass and results in increase of yarn winding tension may aflact the Traveller performanc. Mr.S.Hariharasudhan, Deputy Manager ~ Production, Sree Ayyanar Spinning & Weaving Mills Limited, Unit-2 Kariapatti, Tamilnadu ‘Chase lengths the distance between end of ring rail upward postion and downward position fring ral for one stroke. The recommendation of Chase length forbetter performancein ing ame is Ring Diameter plus 15% to20%, ‘Winding lengthis called as varn delivered per chase. ie, yam wound on the cop for one stroke ofthe ring rail movement. ‘The balloon rotating sped s always lesser than speed spincle due to air resistance, rcton af Traveller and ring, The diferenceof rotational speeds ofthe balloon, Traveller and spindle allows the yarnto be wound onto the bobbin ‘In adkition, the linear winding-on speed needs to match the delivery speed ofthe front rolls, otherwise the yar willbe tight orto slack during spinning. The Traveler dos the function of regulating the spinning tension. The spinning tension shouldbe high enough to have stable balloon and onthe ther hand, the yamtension shouldnot be very high which may lead thigh end breaks. Wining on sped should match the yar dlivery speed. Butas the yam package bulls up, Its circumference changes. Wtha constant bobbin rotation speed, the Traveller needs to change ts ration speed, so thatthe Traveller can set-adustits rotational speed during spining. The magnifientjobis done effectively bythe Traveller very effectively when there is optimum yarn tension at every winding on point. The effective diameter o the cop also increases and occupies the clearing allowance betvean ring and Traveller. The reduction of clearance between Traveller and ring ay lad to high Traveller tf whic i turn gives poor performance. Unwinding performances also to be observed as there are chances of siough- offas the yamcois are aid closely by reducing the chase length. ‘The detailed replies received trom the readers are published in our website: wu nindia.com We have edited replies receved to it the page Felicitation ‘Mr.S.Vijayan Factory Manager, Kiwi Cottspin Mills (P) Limited Mr.Ravindra R Patil, Maintenance Manager, The Ichalkaranji receiving LAT Best Reply Award fram Mr.Sushanta Patinaik, Co op Spinning Mills receiving LAT Best Reply Award from Chief Executive Officer, Lakshmi Ring Travellers (Che) Limited their Chairman and Managing Director Success usually comes to those who are too busy to be looking for itDo you know?

GM cotton increased by 6% in between two years as perthe report Biotech cotton area increased by 6% from 10.8 million hectares in 201610 11.4 milion hectares in 2017. Insect-esistant (Bt tecinology in cotton hybrids delivered broad-baseo benelits by saving losses caused by American bollworm and boosting cotton yield to 500 kg lint per hectare 2s per the latest report from International Service for the Acquisition of Agi-biotech Applications. But to reach the next milestone of 700 pluskg lint, would be difficult unless new technologies are brought in, there is proper implementation of resistant management strategies and a curb on illegal 6M seeds. The next level of targeted cotton yields equal to global average cotton Yield of 700 plus kg lint per hectare, can't be achieved without the introduction of new generation biotech tats, including stacked traits, smartagronomy and high yielding cotton cultivars. The report comes ata time when Monsanto is fighting a legal battle withthe nian government on issues related to intellectual property and introduction fnew products. Another globalagro-giant Bayerhas recently taken over Monsanto and the new entity is yet to make any significant announcement regarding its Indi plan. The ISAAA report shows the popularity of GM crops are mostly restricted in Nort and South American continents and parts of Asia, including three large populous nations - China, India and Pakistan, There ts very litle penetration in Europe and Australia {In 2017, only 24 countries, including USA and Canada grew biotech crops and an additional 43 non-planting countries allow importing biolech crops for food, feed and processing. Biotech soybean varieties ‘accounted for 50% ofthe global biotech crop area. Worldwide, 77% of soybean, 80% of cotton, 22% of maize and 20% of canola were planted to biotech varieties in 2017.
