weaving 39 ( WARP WINDING 1) spinning 46 (sizing process and chemical 3) Welcome to your weaving 39 ( WARP WINDING 1) 1 what is The change in twist of yarn during over end unwinding ? More in case of smaller diameter package More in case of larger diameter package Not dependent on package diameter more dependant on length 2 when the efficiency of the above machine is 91%, additional time(min) required to do the same job is approximately? 10 12 15 25 3.Wind is wind? Number of coils per traverse Number of coils in double traverse Number of grooves in the drum Winding speed in m/min 4 what is mean A 2.5 crossing drum 2.5 turns in a double traverse 5 turns in a double traverse 5 turns in a single traverse 6 turns in a single traverse 5.which parameter pacakgr density independent " Yarn tension Yarn strength Applied package/drum pressure None of the above 6.when Hardness of a cone can be changed if changing ? Traverse Wind per double traverse Wind angle Conicity of the package 7. when surface driven winding package, as the winding proceeds , angle of wind is ? Increases Decreases Remains constant First increases and then decreases 8 what is occur during Pattern formation drum driven winding Low traverse speed High surface speed Low RPM of the drum Ratio of traverse speed to RPM being a whole number 9 which process convert the yarn into cone? warping winding sizing loom 10 Which factor affect the yarn structure during winding? bobbin speed machine speed winding speed machine tension 11.Which process have basic function to convert large package to small ring bobbine? warping winding sizing loom 12.What is yarn clearing? The process of removing objectionable fault The process of removing major fault The process of removing minor fault The process of removing spinning fault 13. What is object of winding? To get continuous length of yarn to wind no of yarn To convert number of single end package to prepare indivisual warp sheet 14.Which process is used for waxing of yarn? sizing loom winding warping 15.Which part of machine used to checkionfg and removing yarn faults? tensioner lectronic scanner Doffing yarn guide 16.Which part of machine used for removing broken and cut yarn? tensioner electronic scanner Doffing Splicer 17.What is the function of tensioner? To establish correct density To establish correct count To establish correct twist To establish correct angle 18.Which part of machine is highly responcible for damage the yarn? tensioner electronic scanner Doffing yarn guide 19.How many types of methods by which tension applied to yarn? 1 2 3 4 Time's up
