**5.1 Loom efficiency of worsted fabrics**

### **5.1.1 Projectile and air-jet loom**

Table 15 shows loom efficiency and stop number of each loom. Fig. 9 and 10 show rpm, efficiency and percentage of end break of Table 15.


Table 15. Efficiency and stop number of weaving loom for the test

Fig. 9. Diagram between rpm and efficiency of various looms

Fig. 10. Percentage of end break of warp and weft to the three looms

As shown in Fig. 9, Sulzer shows high efficiency, on the one hand, air-jet looms, both P-Omni and P-PAT show low efficiency. As shown in Fig. 10, Sulzer loom has high warpbreak but air-jet loom has high weft-break.
