Chain stitch

Applications

Hand embroidery

Chain stitch and its variations are fundamental to embroidery traditions of many cultures, including Kashmiri numdahs, Iranian Resht work, Central Asian suzani, Hungarian Kalotaszeg "written embroidery", Jacobean embroidery, and crewelwork.

Machine sewing and embroidery

Chain stitch was the stitch used by early sewing machines; however, as it is easily unravelled from fabric, this was soon replaced with the more secure lockstitch. This ease of unraveling of the single-thread chain stitch, more specifically known as ISO 4915:1991 stitch 101, continues to be exploited for industrial purposes in the closure of bags for bulk products.

Machine embroidery in chain stitch, often in traditional hand-worked crewel designs, is found on curtains, bed linens, and upholstery fabrics.

Machine variants

• The basic chain stitch is made by first sending the needle down through the material. Then, as the needle rises upward, the friction of the thread against the fabric is sufficient to form a small loop on the underside of the material. That loop is caught by a circular needle which is beneath the work. The machine then moves the material forward projecting the loop on the underside from the previous stitch. The next drop of the needle goes through the previous loop. The circular needle then releases the first loop and picks up the new loop and the process repeats.
• The double chain stitch uses two threads per needle. The boon of the double chain stitch is that from the top side the seam looks tidy and minimalistic like an ordinary lockstitch. The loops are only visible from the bottom side and as such they can be hidden away from view, and away from things that might get caught on them. Double chain stitch is used this way in the construction of denim jeans. Another boon of the double chain stitch over the lockstitch is that no bobbin or bobbin case is required. As such, operators do not have to stop to wind a bobbin after the (relatively small capacity) bobbin runs out. Furthermore, since no bobbin case is required, less room is required underneath the bed of the sewing machine. One example of this is narrow post bed sewing machines for stitching leather reinforcements onto already-assembled gloves. Also the lack of bobbin cases allows two, three, or more needles to be used (still two threads per needle, so a three needle machine would have six threads) at a time, which is useful for topstitching. (Lock stitch machines can accommodate at most two bobbin cases under the presser foot, one positioned to the left of the needles and one positioned to the right. This effectively limits lock stitch machines to having at most two needles.) Finally, double chain stitch is found in bulk material packaging, where it is used to close large bags. As this stitch can be easily unraveled, this permits easy opening of bags sewn shut in this manner.
