           Yarn numbering system       Yarn count  - Count is numrical expresion ,which is determine the fineness and corseness .It also define as yarn is  thick and thin.A definition given by textile institute,"count number is indicate the weight per unit lenght or lengthy per unit weight " Count = Weight /length             =Length/Weight There are two     of yarn numbering system 1. Indirect  number system -English cotton                                      Count ,metric count 2. Direct number system   - Tex ,Denier       1. Indirect number - In this system length  unit weight .In this system weight is constant and length is variable .Yarn thickness is indirectly proportional to yarn number . Higher the count finer the yarn ,vice v...

Step Taken to prepared the size paste   1.Take standard volume 700 lit water  normal temperature into pre mixture water flow meter start the stirring 2. Properly way all chemical required 3. Add a modify ,starches PVA, acrylic Binder slowly into pre mixture 4. Stirring mixture for 15 min 5 transfer  the pre  mixture into the closed vessel cooker 6. Close all open wall of the cooker 7.Heat the cooker mixture with injection of steam will Auto cut  when cooker cooker temperature reaches limit is 100 to 110 degree Celsius, take around 30 to 35 minutes 8. Cook the mixture for another 45 minute temperature of the cooker reach 120 degrees celsius depend upon the size recipe 9. Start the stirr of storage Vessel then the Transfer cooked  respective  to storage  vessel 10. Add the lubricant with the size paste at storage vessel 11. Maintain the storage vessel temperature 80 to 90 degree Celsius 12. Paste  ready to transfer the size box to...

Object   of sizing 1 To improve abrasion resistance of yarn   2 .To reduce the hariness of yarn 3 .To improve the wevability of warp 4 .To improve the breaking strength of yarn 5 .To reduce the generation of static charge for polyester blend yarn What sizing should not do ? 1 .It not should  elongation and  break of yarn 2. There should not increasing in  missing and cross end Chartertisct of size yarn  1 . Increase in the strength 10 to 20% of yarn 2 . lower elongation 3.Higher bending rigidity 4 .Higher abrasion resistance 5 . Lower hariness 6 .Lower frictional resistance Why sizing department is important?      Sizing is most important process it can make or it can mar the weaving performance .one high speed sizing machine can control the working of 100 to 200 looms depending on count of yarn ,size addon , fabric construction ,speed of sizing machine .         ...
