The "Magic Machine" from Fabric to Garment: How Circular Knitting Machines Reshape the Textile Industry?

The cotton T-shirt on your body, the elastic fabric of your sports jacket, and the soft bedding and curtain fabrics at home may all come from the same "textile magic weapon" — the circular Knitting Machine. Scientifically named "circular weft knitting machine", this equipment has become the "main force" of the global textile industry thanks to its core advantages of high-efficiency mass production and diverse patterns. Today, with the penetration of AI and IoT technologies, this "veteran machine" is radiating new intelligent vitality, evolving from a traditional manufacturing tool to a core engine driving the digital transformation of the industry.

A circular knitting machine is the core equipment for producing weft-knitted fabrics. It drives knitting needles to operate at high speed through a circular needle cylinder, bends yarns into loops, and interlocks them to form tubular or flat fabrics. Its "efficiency" stems from its unique structure: a single machine is usually equipped with dozens or even hundreds of loop-forming systems (commonly known as "yarn feeding paths"), with a rotational speed of up to several hundred revolutions per minute. Its daily output far exceeds that of traditional looms, and it can directly weave seamless tubular fabrics, significantly reducing subsequent cutting processes.

In terms of classification, circular knitting machines are mainly divided into two major series: single-sided and Double-sided.Single-sided machines have only one needle cylinder and are good at producing single-sided fabrics such as plain cloth and terry cloth. Double-sided machines are equipped with two vertically arranged needle cylinders (upper and lower) and can weave double-sided fabrics with better elasticity such as ribbed cloth and interlock cloth, which are widely used in underwear and sportswear. Special models such as jacquard circular knitting machines control the selection of knitting needles through computer programs, enabling them to weave complex patterns and even switch multi-color yarns in real time to meet fashion design needs.

Its core structure can be called a "precision cooperative system": the yarn feeding mechanism ensures uniform yarn tension; the knitting mechanism (known as the "heart of the machine") completes the loop-forming action through the cooperation of the needle cylinder, knitting needles, and cams; the take-up and winding mechanism neatly winds the fabric; coupled with auxiliary systems such as lubrication and dust removal, and electrical control, it jointly guarantees stable production under high-speed operation. It is worth mentioning that the safety design of modern circular knitting machines is quite complete — the machine will automatically stop when the protective door is opened to avoid operational risks.

The products of circular knitting machines have long been integrated into all aspects of life. According to application fields, the fabrics produced can be divided into three categories: apparel textiles (with the highest proportion), including close-fitting clothing such as T-shirts, hoodies, and stretch pants; home textiles such as bedding, towels, and curtains; and technical textiles, which are used in professional scenarios such as medical protection, industrial filtration, and automotive interiors.

China is the global core of production and consumption of circular knitting machines. Data shows that the annual output of circular knitting machines in China has reached 60,000 units, accounting for 95% of the global total. Production bases are mainly concentrated in the Xiamen-Zhangzhou-Quanzhou area, forming a complete supply chain from whole machines to 60% of accessories, with an annual output value exceeding 20 billion yuan. In global industrial hubs such as Tirupur (India's "Knitting Capital") and Turkish textile clusters, Chinese-made circular knitting machines have become the preferred equipment for local enterprises' large-scale production.

As the textile industry transforms towards "automation, informatization, and unmanned factories", the development of circular knitting machines will focus on three major directions: first, a higher level of intelligence to realize the full-process digitalization from design and production to quality inspection; second, modular design to improve equipment compatibility and upgrade flexibility, reducing enterprises' investment costs; third, green upgrading to further reduce energy consumption and carbon emissions.

In terms of global layout, Chinese enterprises represented by FEADSFON are accelerating their overseas expansion.

Today, this "magic machine" is still constantly iterating, and will unlock more possibilities in the future — perhaps in the near future, the clothes on your body will be tailor-made by intelligent circular knitting machines in "dark factories" based on your body data.
