  17. Yarn manufacturing…. Spun yarn Spun yarns are made by mechanical assembly and twisting together (spinning) of staple fibers. Multi-filament yarn A multi-filament yarn is a filament yarn made from multiple filaments assembled with or without twist. Monofilament yarn A monofilament yarn consists of only a single continuous filament Presented by:Md.Dhaberul Islam (Dabir)

  18. Yarn manufacturing…. Assembled yarns Two or more yarns which are wound side by side on to the same package, but without twisting around each other, are called assembled yarns. Folded or plied yarns Folded or plied yarns are yarns made by twisting together two or more single (and/or folded) yarns of the same or different types. Presented by:Md.Dhaberul Islam (Dabir)

  21. Woven construction….. Presented by:Md.Dhaberul Islam (Dabir)

  22. Knit construction….. Presented by:Md.Dhaberul Islam (Dabir)

  23. Stitch types As per the ISO classification there are 6 stitch types. Class 100 - Chain Stitch Each loop is interconnected with the following loop of the same thread. Opposite sides of the seam look different. This stitch type can be very easily unpicked by running back from the last stitch to the first. The seam is generally quite extensible. It is often used for temporary stitching. Presented by:Md.Dhaberul Islam (Dabir)

  24. 101 class Single thread chain stitch using one needle thread and one blind lopper Typical uses; Basting, Bag closing, Hat construction, and Buttonsew Presented by:Md.Dhaberul Islam (Dabir)

  25. 103 class Single Thread Chainstitches Using One Needle Thread and One Blind Looper Typical uses; Blindstitch Hem on Cuffs, Bottoms, etc. Presented by:Md.Dhaberul Islam (Dabir)

  26. 104 class Single Thread Chainstitches Using One Needle Thread and One Blind Looper Typical uses; Embroidery, Blindstitch Hem on Cuffs, Bottoms, etc Presented by:Md.Dhaberul Islam (Dabir)

  27. Class 200 - Hand Stitch Formed by single threads being passed completely from one side of the material to the other. The thread is held by the material. Originally made by hand, some of them can now also be formed by machine. 202 class Single Thread Hand Stitch Using One Needle Thread Typical uses; Basting, Tacking and Repairs Presented by:Md.Dhaberul Islam (Dabir)

  28. 205 class Single Thread Stitch Using One Needle Thread Typical uses; "Pick Stitch" Topstitch Presented by:Md.Dhaberul Islam (Dabir)

  29. Class 300 - Lock Stitch Formed by two different thread systems. A needle thread introduced from one side of the material is interlaced with an under thread supplied from a spool from the other side. The stitch is difficult to unpick and both sides have the same appearance. Generally, lock stitches are less extensible than chain stitch seams. This type finds the widest application. Two or more thread lock stitch using needle threads and one bobbing thread Presented by:Md.Dhaberul Islam (Dabir)

  30. 301 class Two Thread Lockstitch Using One Needle Thread and One Hook (bobbin) Thread Typical uses; General Seaming, Topstitching, etc. Presented by:Md.Dhaberul Islam (Dabir)

  31. 304 Class Two Thread Zig Zag Lockstitch Using One Needle Thread and One Hook (bobbin) Thread Typical uses; General Seaming, Topstitching, Coverstitching, Knits or Wovens where moderate stretch or greater coverage is required Presented by:Md.Dhaberul Islam (Dabir)

  33. Class 400 - Multi thread chain stitch This also formed from two thread systems. The loops of the needle thread are drawn all the way through the material and they are interconnected on the under side by thread supplied from a looper. Top and bottom sides have a different appearance. The stitch can easily be unpicked and is quite extensible. Special applications are elastic cross-over seams, seams in knitted fabrics and seams which have to be flat. Multi thread chain stitch using one or more needles thread and one or more loppers thread Presented by:Md.Dhaberul Islam (Dabir)

  36. Class 500 - Overage chain stitch Overage chain stitches are formed from one or more needle and/or looper threads. Needle thread loops are taken all the way through the material and are interconnected with themselves or with another thread. At least one thread system passes around the edge of the material. Overage stitches of various types are used to neaten and to bund the cut edges of woven and knitted materials.

  44. Class 600 - Covering chain stitch This stitch type is generally formed from three thread systems. The cover threads lie on the top surface and are held in place by the needle threads which in turn are interlaced on the back of the seam by the looper threads. They are used specially for making flat extensible seams in knitted fabrics. Multi-Thread Coverstitches Presented by:Md.Dhaberul Islam (Dabir)
