weaving 45(sizing process and chemical 2) spinning 46 (sizing process and chemical 3) Welcome to your weaving 45(sizing process and chemical 2) 1 Which roller is used for Removing excessive size paste? Measuring roller Marking roller Pressure roller Squezing roller 2. What is the cause and defeact of Improper build for beam ? Improper adjustment of measuring and marking mechanism. Incorrect spreading of yarn ends in the reed dents The size boxes and machine metal parts are dirty The size is cooked in non-galvanized iron kettles. 3.What is the cause of dirt stains in warp ? Excessive application of size material Due to not crushed or grind the size material The size boxes and machine metal parts are dirty Due to over and under sizing 4.What is the cause of incorrect warp length ? Dilution of size Variable size level Due to not optimum viscosity of the size solution Improper adjustment of measuring and marking mechanism 5.Which is important parameter for better sizing? machine speed Marking roller speed Pressure roller speed Squezing roller speed 6.What is full form of LCB? liner control beam lap control beam lea chain beam long chain beam 7.Why sizing is important ? Because of its capacity of tear resistance is more Sizing gives a protective coating on yarn surface and reduce breakages To improve the weaveability Making it more resistant 8.What is the use of sizing agents ? Dye penetration should be properly done. To protect the warp from the rigours of weaving. Used to provide water-resistance of fabrics Used to increase absorbency of fabric. 9.What is the objective of sizing ? To decrease the smoothness of warp yarn To reduce hairness of warp yarn To decrease the elasticity of yarn. To decrease the tensile strength of yarn 10.Which process play importtant role during sizing? loading of beam size paste machine speed machine temperature 11.How many types of sizing are there ? 3 2 4 7 12.What is the percent of light sizing ? 10 to 15 05 to 08 02 to 09 12 to 13.5 13.What is the percent of Heavy sizing ? 25 to 33 50 to 100 30 to 45 55 to 60 14.What is the causes of fault in sizing ? Weak squeezing Proper size feed to the size box. Due to insufficient size concentration Due to insufficient splitting of starch. 15.What is the cause of gum spots and smears ? Long stoppage of machine during sizing Very high temperature in the drying section Low sizing speed Bad stirring of starch at preparation 16.What is the cause of non uniformsize regain ? Irregular heating of the size in the box Lease rods are set too far apart Broken ends are improperly pieced up Bad warping 17.What is input of sizing process? Dyeing beam waping beam loom beam Sizing beam 18.What is output of sizing process? Dyeing beam waping beam loom beam Sizing beam 19.Which process is basic for sizing process? Dyeing waping loom making receipy 20.What is the colour of size paste? milky whiter yellow blue yellow Time's up
