Know the difference between double jersey and single jersey knitting machines

Introduce:
In the field of textile manufacturing, the choice of knitting machine is a critical decision that can significantly affect the quality and characteristics of the fabric produced. Two widely used types of knitting machines are double jersey and single jersey. Although both machines are used to produce knitted fabrics, they have unique capabilities to produce fabrics with different characteristics. Knowing the difference between double jersey and single jersey machines is essential for manufacturers and textile enthusiasts alike. In this blog post, we’ll delve into the technical aspects of these machines, their operational variations, and the fabrics they make.
Interlock knitting machine:
Double knitting machines are known for their versatility and ability to produce high-quality double-sided fabrics. These machines consist of two needle beds, each with its own needle group. The presence of two beds enables the interlock machine to form two layers of knitted fabric simultaneously. Thus, an interlock fabric has two distinct sides – one with vertical wales and the other with horizontal weaves.
Main features:
1. Double-sided structure: Double-sided cloth has a smooth surface on both sides, making it double-sided. This feature adds to their versatility and aesthetics, as both sides of the fabric can be used.
2. Higher elasticity: Compared with single-jersey knitted fabric, double-sided fabric has greater elasticity due to its double-sided structure. This quality makes it ideal for applications that require stretchability, such as sportswear and sportswear.
3. Enhanced Stability: The interwoven fabric has improved dimensional stability, ensuring minimal deformation or stretching during wearing or washing. This stability is due to the interlocking structure of the fabric.
Single jersey knitting machine:
Single jersey knitting machines are widely used in the textile industry due to their efficiency and ability to produce a variety of knitted fabrics. These machines consist of individual needle beds arranged in a circular arrangement. The circular arrangement of the needles ensures a single-ply knit.
Main features:
1. Single-jersey construction: One side of a single-jersey fabric is smooth and the other surface presents visible loops. This one-sided structure limits their reversibility and utility.
2. Diagonal wale appearance: Single jersey fabrics exhibit a slanted wale appearance, which gives them their characteristic diagonal lines. This feature adds a visually interesting element to the fabric and is often used in fashion garments.
3. Versatility: The single-sided machine can produce a variety of fabrics, including light, medium-thick, and even some heavy-weight fabrics. This versatility enables manufacturers to meet different market demands.
Operational differences:
Interlock sewing machines and single jersey machines differ greatly in their operating mechanisms. The interlock sewing machine uses two needle beds, requiring the needles to move independently and synchronously. On the other hand, single jersey machines use only one needle bed and work on the principle of overlapping stitches. Operational changes directly affect the speed, type of fabric produced and efficiency of each machine.
In conclusion:
Choosing between double jersey and single jersey machines is an important decision for textile manufacturers. Both types of machines have their unique features, advantages and limitations. Interlock machines excel at producing double-sided, elastic, and dimensionally stable fabrics, while single-jersey machines offer greater flexibility and a variety of fabric options. By understanding the differences between these machines, manufacturers can make informed decisions that lead to improved fabric quality, increased productivity and overall customer satisfaction.
