Máquina de punto de jersey único vs máquina de punto de jersey doble

Knitting is a traditional textile manufacturing method that produces fabrics by interlocking loops of yarn. Knitting machines have revolutionized the textile industry, making manufacturing faster, more efficient, and cost-effective. Two of the most commonly used types of knitting machines are the single jersey knitting machine and the double jersey knitting machine. In this article, we will explore the differences between these two machines, their applications, and their advantages and disadvantages.

What is a Single Jersey Knitting Machine?

Single jersey knitting machines feature a single 'cylinder' of needles and can produce plain fabrics. Plain knitting is the simplest type of structure and has been used since the inception of knitting technology. It can be done both by hand and machine (flat and circular). Plain fabrics are used in various garments requiring stretch, such as blouses, t-shirts, tops, and casual dresses.

What is a Double Jersey Knitting Machine?

Double jersey knitting machines have two sets of needles, which allow the production of fabrics that are twice as thick as single jersey fabrics. Common fabrics produced by double jersey knitting machines include rib and interlock fabrics.

Rib Double Jersey Machine

In rib double jersey machines, the two sets of needles are arranged at right angles to each other, with one set on the cylinder (vertical position) and the other on the dial (horizontal position). This arrangement allows for the vertical movement of needles on the cylinder and horizontal movement of needles on the dial, creating a rib pattern. Rib knit fabrics are reversible with distinct vertical ribs on both sides, produced by alternating knit and purl stitches. These fabrics are often used for cuffs, neckbands, and waistbands, or any edge that should be form-fitting. Rib knit fabrics are typically made from cotton, cotton blends, wool, or acrylic.

Differences Between Single Jersey and Double Jersey Knitting Machines

Needle Arrangement

Single jersey circular knitting machines have only vertical needles, whereas double jersey circular knitting machines have both horizontal and vertical needles.

Knitting Method

The knitting methods differ between the two machines. Single jersey knitting machines knit in one direction, while double jersey knitting machines knit in two perpendicular directions.

Use of Sinkers

Single jersey knitting machines require sinkers to produce fabric, as sinkers are crucial in loop formation. Double jersey knitting machines, however, do not require sinkers.

Fabric Thickness

The fabric produced by single jersey circular knitting machines is thinner compared to that produced by double jersey machines.

In conclusion, single jersey and double jersey knitting machines each have unique features and applications. Understanding these differences helps in selecting the right machine for specific textile manufacturing needs.
