In the context of the knitting industry's continuous pursuit of efficiency, intelligence and personalization, the Three System Computerized Flat Knitting Machine, as an advanced horizontal knitting equipment, has attracted more and more attention from knitting companies and designers. Especially today when seamless and shaped garment technology has gradually become an industry trend, whether the technical capabilities of the three-system flat knitting machine can handle the production of these complex structures has become a key topic.

1. What is a three-system computerized flat knitting machine?

A three-system computerized flat knitting machine refers to a flat knitting machine with three independent but coordinated needle selection systems (knitting systems) in the needle bed system. Each system can independently knit, transfer, sink, pick yarn, etc., making the machine more flexible and efficient in the weaving process. Compared with a single system or a double system, a three-system can achieve more complex structures and patterns, greatly improving production efficiency and knitting freedom.

2. Production requirements for seamless and three-dimensional shaped garments
1. Seamless Garment
The core of seamless technology is one-time shaping, which reduces traditional sewing processes and improves wearing comfort. Seamless knitting requires machines to have:
Precise link control
Multi-directional yarn feeding capability
Highly integrated programming system
Flexible loop and yarn transfer functions
2. Shaped Garment
Three-dimensional shaping emphasizes that garments have basic structures during the knitting process, such as waist, swing expansion, shoulder design, etc., to reduce cutting and splicing. It requires:
Multi-system coordinated work
Flexible needle position conversion
High-precision density control
Partition adjustment and dynamic tension control
3. Applicability analysis of three-system computer flat knitting machines
1. Applicable to the production of partial seamless structures
Although the truly "completely seamless" production is still dominated by circular knitting machines, the three-system flat knitting machines can achieve partial seamless effects through the cooperation of multiple systems, such as seamless splicing of shoulders, necklines, and cuffs. Some "fake seamless" products also use three-system machines to weave key parts in one piece to achieve structural continuity.

2. Very suitable for three-dimensional knitting
The most prominent advantage of the three-system computerized flat knitting machine is its performance in three-dimensional structure forming. The three systems can realize synchronous or alternating knitting, making the pattern design more three-dimensional, such as:
Variable density knitting pieces
Arcuate structure
Complex needle narrowing and needle adding design
Integrated knitting of garment pieces with a strong sense of integrity (such as molded sweaters, wool skirts, knitted jackets, etc.)

3. Improve efficiency and reduce manual intervention
Since the three systems can process multiple areas or patterns at the same time, the overall weaving efficiency is improved. In the complex knitting process of three-dimensional forming, manual operations such as changing yarns and changing thread ends are reduced to achieve intelligent and integrated production.

4. Limitations in practical applications
Although the three-system flat knitting machine has advantages in three-dimensional knitting, it is still limited by the structural characteristics of horizontal knitting in completely seamless production. Real circular knitting (such as seamless underwear and tights) is still mainly based on circular weft knitting seamless machines. Therefore, the three-system flat knitting machine is more suitable for the development of clothing in the two directions of "partial seamless" and "three-dimensional forming".

With the advantage of multi-system collaborative work, the three-system computerized flat knitting machine has demonstrated its strong strength in the production of three-dimensional knitted products. Although it still has limitations in "completely seamless" weaving, it is undoubtedly a cost-effective and highly flexible solution for partial seamless structures and one-piece clothing molding technology. With the improvement of knitting design software and machine intelligence, the three-system computerized flat knitting machine will play a more important role in the future of personalized, automated and environmentally friendly knitted clothing.
