  5. KNITTING SECTION CIRCULAR & FLAT

  6. It is the method of creating fabric by transforming continuous strands of yarn into a series of interlocking loops. Each raw of such loop hanging from the one immediate preceding it.

  7. Raw material is a unique substance in any production oriented textile industry. It plays a vital role in continuous production and for high quality fabric.

  8. Raw material Types In knitting section, for knitting fabrics only yarn is used as raw materials. 1. Cotton yarn: (A). Combed. (B). Carded. 2. Polyester yarn: (A). Normal. (B). Micro. 3. CVC. 4. Grey Melange (C-90%, V-10%) 5. Ecru Melange (C-85%, V-15%) 6. Anthra Melange (C-65%, V-35%) 7. Spandex (Lycra). 8. PC 9. Mixed melange 

  9. Count of yarn Used in this Ind.  Carded Yarn: 20’s to 40’s  CVC : 20’s to 40’ s  PC :24’s, 26’s, 28’s, 30’s  Spandex(Lycra) : 20D, 40D, 70D  Combed yarn: 24’s to 36’s  Gray Melange : 20’s to 40’s  Polyester Yarn : 75D, 100D

  10. Classification of Knitting Section 01. Flat knitting section 02. Circular knitting section 03.Fabric inspection section 04. Maintenance & Mechanics

  11. Relationship between knitting parameters  1. Stitch length increase with the decrease of GSM.  2. If stitch length increase then fabric width increase and WPI decrease.  3. If machine gauge increase then fabric width decrease.  4. If yarn count increase (courser) then fabric width increase.  5. If shrinkage increases then fabric width decrease but GSM and WPI increase.  6. For finer gauge, finer count yarn should use.

  12. PRODUCTION CALCULATION Production/shift in kg at 100% efficiency =      . . ( ) 60 8 RPM Feeder × 2.54 × 10 No of No 840 Needle 2.2046 × of SL mm   36 × Yarn count No. of Needle = DG (for S/J) = = DG 2 (for Rib) DG (for Interlock) Generally, Machine R.P.M =

  13. G.S.M. It is technical term that indicates the weight of the fabric per square meter.

  14. METHODS OF INCREASING PRODUCTION  1. By increasing m/c speed:  2. By increasing the number of feeder:  3. By using machine of higher gauge:  4. By imposing automation in the m/c:  5. By imposing other developments:

  23. DYEING SECTION

  24. DYEING The process by which a textile material is changed physically or chemically so that it looks mono uniform colored is called dyeing.

  25. Flow Chart of Dyeing…. Grey Fabric Inspection Batch Section Batching Load on Machine Scouring Bleaching Enzyme Leveling Electrolyting Dyeing Softening Unload Machine

  26. LAB DIP Lab Dip Development means the sample which is dyed according to buyer’s requirements (similar shade and so on).Depending on lab dip development sample dyeing and bulk production dyeing planning done. OBJECT OF LAB DIP  The main objectives in lab dip are as follows.  To calculate the recipe for sample dyeing.  To compare dyed sample with swatch by light Box or VERVIDE Color Cabinet .  To calculate revise recipe for sample dyeing.  Finally approved Lab Dip(Grade: A B C)

  27. STOCK SOLUTION: In Chemistry a stock solution is a large volume of a common reagent at a standardize concentration.  Why Stock solution is required in laboratory: The dyes which are supplied by different dyes and chemical companies are in solid form. When we need to dye a sample fabric we need to dissolve the dye and for this reason as per the requirement of shade darkness or lightness we required different concentration of dye solution. As a result stock solution is very important in laboratory process.

  28. Batch Preparation: Batching is the process to get ready the fabrics which should be dyed and processed for a particular lot of a particular order.  Objective of Batching:  To receive the grey fabric roll from knitting section or other source.  Turn the grey fabric if require.

  29. Possible Dyeing Faults… 1. Uneven Shade 2. Running Shade 3. Crease Mark 4. Oil Spot 5. Softener Spot 6. Dyeing Hole 7. Roll to roll shade variation

  30. PROJECT WORK

  31. Hole Mark  Causes:  Holes are the result of yarn breakage or yarn cracks.  During loop formation the yarn breaks in the rejoin of the needle hook.  Badly knot or splicing.  Yarn feeder badly set.  Remedies:  Yarn strength must be sufficient to withstand the stretch as well as uniform.  Use proper count of yarn.  Correctly set of yarn feeder.  Knot should be given properly

  32. Needle Mark  Causes:  When a needle breaks down then needle mark comes along the fabrics.  If a needle or needle hook is slightly bends then needle mark comes on the fabrics.  Remedies:  Needle should be straight as well as from broken latch.

  33. Sinker Mark  Causes:  When sinker corrode due to abrasion then some times can  not hold a new loop as a result sinker mark comes.  If sinker head bend then sinker mark comes.  Remedies:  Sinker should be changed.

  34. Star Mark  Causes:  Yarn tension variation during production.  Buckling of the needle latch.  Low GSM fabric production.  Remedies:  Maintain same yarn tension during production.  Use good conditioned needle.

  35. Pin Hole  Causes:  Due to break down or bend of the latch, pin hole may come in the fabric.  Remedies:  Change the needle.

  36. Rust stain  Causes:  If any rust on the m/c parts.  Remedies:  If any rust on the m/c parts then clean it.  Proper maintenance as well as proper oiling.

  37. Grease Stain  Causes:  Improper greasing.  Excess greasing.  Remedies:  Proper greasing as well as proper maintenance.

  38. Cloth fall-out  Causes:  Cloth fall-out can occur after a drop stitch especially when an empty needle with closed latch runs into the yarn.  Remedies:  Make sure all the latches of needle are closed with feeding yarn after a drop stitch.

  39. SLUBS  Causes:  Occur during spinning process  Improper winding  Snagging  Extra fly yarn knitted on the fabric  Remedies:  Use proper count of yarn.  Correctly set of yarn feeder.  Knot should be given properly.

  40. LYCRA DROP  Causes: Lycra yarn tension vary time to time Weak place in lycra yarn.  Remedies: Lycra yarn tension should be adjust. Better Quality lycra yarn used.

  41. TECHNICAL TEXTILE The definition of Technical textiles adopted by the authoritative Textile Terms and Definitions, published by the Textile Institute, is “Textile materials and products manufactured primarily for their technical and performance properties rather than their aesthetic or decorative

  42. Fiber used in Technical Textiles  1. Conventional fibers.  2. High strength and high modulus organic fibers.  3. High chemical- and combustion-resistant organic fibers.  4. High performance inorganic fibers.  5. Ultra-fine and novelty fibers.  6. Civil and agricultural engineering fibers.  7. Automotive and aeronautics fibers.  8.
