#Textile #Spinning #RingSpinning #Gate #Tf_Gate Following are the disadvantages of choosing Ring Spinning Process Process stages are more numerous, Roving stage exists as an extra process compared to the other systems. Yarn breakages are more numerous as a result of ring traveler friction and yarn air friction. interruptions, broken ends, and piecing up problems exist because of the yarn breakages. The high speed of the traveler damages the fiber. The capacity of the cops is

#Textile #Gate #Tf_Gate #Calculations #Spinning Q: What is the relation between CV% and U%? Also, write the difference between both. Ans: C.V. % = 1.25 X U% The irregularity U% is proportional to the intensity of the mass variations around the mean value. The U% is independent of the evaluating time or tested material length with a homogeneously distributed mass variation. The larger deviations from the mean value are much more intensively taken into consideration in the calc

#Textile #Winding #Spinning #QandA #Gate #TF_Gate Q. Compare between ordinary & automatic shuttle. Ans: Q. State the Importance or Effects of tensioning Device. Ans: Too high tension: Can damage the yarn. The breakage rate may be greater. Elongation properties may change. Too low tension: Can lead to unstable or loose packages which will not unwind cleanly. Variation in yarn tension in different parts of a wound package can cause undesirable effects. For MMF: Too high tension

#Textiles #Winding #QA #Spinning Q: What is winding? Why winding is necessary for weaving? Ans: Winding; Winding is the process of transferring yarns from the ring, bobbin, hank, etc into a suitable package. It may be electrical or mechanical. Warp → cone, cheese, flanged bobbin. Weft → pirn, cop. Objects or necessary: To transfer yarn from one package to another suitable package, this can be conveniently used for weaving purposes. To remove yarn faults like hairiness, neps,

#Textile #Count #Gate #Tf_Gate #Yarn #Testing #Spinning The following instrument is generally used to determine the count of the yarn with the wrap reel. The wrap reel is used to prepare the sample of length 120 Yards. Analytical Balance. Knowles Balance. Quadrant Balance. Beesley Balance. Stubb yarn Balance. Analytical Balance: In the mills, the leas of yarn are wrapped using the wrap reel and their weight is found out using the analytical balance. The weights are measured i
