YARN CLEARER INFORMATION

1.Winding speed should be around 1250 meters/ min

2. Machines with tension management is preferred

3. Clearer settings should be as close as possible. Loepfe Yarn master setting is given below

N -4.0 (nep) : DS-2.0 (short) : LS-1.6 (short) : DL-1.18 (long) : LL-40 : (long) -DS-14%(thin) : -DL-40(thin)

Since Loepfe has a facility of class clearing. "C"s to be added in such a way that the following faults which are

displayed in Loepfe class clearing should be cleared.

A4,A3,B4,B3, B2(50%),C1,C2,C3,C4,D1,D2,D3,D4,E,F,G,H1(50%),H2,I1,I2

4. Count channel setting should be less than 7%

5. Setting for cluster faults should be set such that, if a yarn produced without bottom apron, or damaged rubber

cots is fed, it should be cut by the clearer

6. Long thick faults in the cone yarn should be zero

7. Long thin faults should be zero

8. If the waxing attachment is below the clearer, the clearer should be cleaned once in a day

9. Splice strength should be more than 75% of yarn strength

10. Splice appearance should be good and all the splicers should be checked at-least once in a week

11. Good quality wax should be used

• wax pick up should be around 0.1%

• uniform application of wax to ensure uniform coefficient of friction (0.125 to 0.15)

12.Uniform moisture in the cones is important, because coefficient of friction varies as a function of moisture

13. All wax rollers should rotate properly

14.Repeaters should be as low as possible, because this will affect the package quality

15. It is advisable to produce cones with 1.8 to 2.4 kgs

16. Yarn tension in winding should not be very high

17. Imperfection increase between ring frame and winding should not be more than 30% for cotton combed yarns
