Circular machines: the technology behind seamless sweaters
Circular or tubular machines are tools used for producing knitted fabrics through a continuous and rotary motion. Unlike flatbed machines, which create flat fabrics, circular machines knit in a circular manner, generating a tube of fabric. This process is particularly suitable for making seamless garments, offering superior comfort and an optimal fit. Let's explore together with the help of the article from "Exapro.it" how they work.
What are circular knitting machines?
Circular machines are designed to knit continuously, creating a tubular fabric that requires no side seams. This technology is especially valued in the production of garments such as sweaters, socks, gloves, and underwear, where comfort and adaptability are essential.
There are various types of circular machines depending on the type of knitwear to be produced: single jersey machines for lightweight fabrics, double jersey machines for heavier fabrics, rib machines for elastic knits often used in cuffs and necklines, and interlock machines for versatile knitted fabrics.
How do circular machines work?
The operation of a tubular machine is based on a rotating cylinder around which the needles are arranged. During processing, the yarn is fed to the needles which, moving in a circular motion, create a continuous knitted structure. This method allows the production of fabrics with a smooth and uniform surface, minimizing joints and seams.
1. Yarn feeding: the yarn is loaded onto the bobbins and fed directly to the machine's needles. This system ensures a constant and uniform flow of material.
2. Circular knitting: the needles, arranged in a circle, work simultaneously to create a fabric tube. The circular structure allows the production of seamless garments, increasing comfort and reducing processing times.
3. Pattern programming: modern tubular machines are equipped with advanced software that allows programming complex designs.
4. Finishing and cutting: after knitting, the fabric tube can be finished and cut to create the desired garment. Thanks to the tubular structure, the finishing process is faster and requires fewer steps.
What are the advantages of circular machines?
Circular machines offer numerous advantages in knitwear production:
- Seamless: the main feature of tubular machines is the ability to produce garments without side seams, improving comfort and fit.
- Production efficiency: continuous processing and fewer finishing steps make the process faster and less expensive.
- Versatility: these machines can be used to produce a wide range of products, from simple underwear to complex sweaters with intricate designs.
- Waste reduction: the absence of seams reduces fabric scraps, making the production process more sustainable.
Applications of Circular Machines
Circular machines are used in various sectors of knitwear:
- Hosiery: Production of seamless socks and tights.
- Underwear: Production of seamless intimate wear for superior comfort.
- Knitwear: Creation of sweaters, t-shirts, jumpers, and other knitted garments.
Circular machines represent a revolution in the world of knitting, allowing the creation of seamless garments that combine comfort, quality, and style.
