Top 10 Questions for Overlocker Interview

1. What is the difference between a 2-thread overlock and a 3-thread overlock?

An overlocker, also known as a serger, is a sewing machine that sews fabric edges to prevent fraying and give the fabric a professional finish. There are two main types of overlockers: 2-thread and 3-thread.

• A 2-thread overlock uses two threads to create a chain stitch that wraps around the edge of the fabric. This stitch is very stretchy and durable, making it ideal for fabrics that are likely to stretch or fray, such as knits and sportswear.
• A 3-thread overlock uses three threads to create a stitch that is even stronger and more durable than a 2-thread overlock stitch. The third thread is used to create a cover stitch that runs along the edge of the fabric, giving the fabric a more finished look.

Serged stitch

• This stitch is very stretchy and durable, making it ideal for fabrics that are likely to stretch or fray, such as knits and sportswear.

Mock safety stitch

• The mock safety stitch is a variation of the serged stitch that uses a fourth thread to create a cover stitch along the edge of the fabric.
• This stitch is stronger and more durable than a serged stitch, and it gives the fabric a more finished look.
