The main difference between computer chain stitch multi-needle quilting machine and computer lock stitch multi-needle quilting machine

The main difference between a computerized chain stitch and a computerized lockstitch is the type of stitch they produce. Here are the main differences:

Stitch Type: A computerized chain stitch quilting machine produces a chain stitch, where the needle forms a loop on the underside of the fabric and the looper grabs the thread to form an interlocking loop. This type of stitch is known for its flexibility and elasticity, making it suitable for quilting applications that require stretch or decorative effects. On the other hand, a computerized lockstitch quilting machine produces a lockstitch, which consists of two threads that interlock between layers of fabric. This stitch provides a strong and secure seam and is commonly used in quilting for its durability and resistance to unraveling.

Thread Use: Chain stitch machines typically only require one spool of thread, as the needle and looper work together to form the stitch. In contrast, lockstitch machines use two separate spools of thread (one for the top thread and one for the bottom thread) to create the interlocking stitch. This double thread setup provides additional strength and stability to quilted seams.

Backstitch: Chainstitch machines have an inherent backstitch feature, meaning they can sew in reverse without the need for an additional mechanism. This feature is useful for protecting the beginning and end of quilting threads. Lockstitch machines require a separate backstitch mechanism or feature for reverse sewing.

Machine Speed: Chainstitch machines generally have higher sewing speeds compared to lockstitch machines. Chainstitch formation requires less thread movement and allows for faster sewing speeds. However, it is important to note that actual stitching speeds may vary depending on the specific machine model and other factors.

Applications: Both chainstitch and lockstitch multi-needle quilting machines are used in the quilting industry. Chainstitch machines are often used for quilting mattress panels, upholstery, and other applications that require flexibility and decorative sewing. Lockstitch machines are suitable for general quilting tasks and are often used for quilting patterns, borders, and holding quilt layers together.

When choosing between a computerized chain and lock quilting machine, consider the specific requirements of your quilting project, such as stitch type, fabric type, desired decorative effects, and production speed. Consulting with the manufacturer or industry experts can provide further guidance in selecting the machine that best suits your needs.
