An automatic knitting machine creates knits and is typically powered by electricity. There are several types of these machines, and they may vary in specifics such as how they are operated and the fabrics they can handle.
Circular Knitting Machine:
This machine creates tubular fabrics. It produces items like T-shirts, socks, and innerwear. It works by lapping a single yarn thread around a needle at a set point.
Computerized knitting machines:
These devices allow the operator to create complex knitting patterns using a computer. The connection between the device and the computer can be wired or wireless. They are useful for producing customized sweaters, scarves, and socks. Designs can be easily uploaded and downloaded, and there is also the option of saving various designs for use later. Automatic adjustments are made in real-time according to what is on the screen. This ensures that the machine operates at the optimal level. These machines may sometimes be referred to as CNC (Computer Numerical Control) knitting machines. The CNC technology means these knitting machines are automatic and operate with a high level of accuracy. They may include lace knitting machines. Another type of automatic knitting machine with computer assistance is the CAD automatics. Here, the CAD (Computer-Aided Design) software helps to create the knitting design. The machine then follows this design to accurately create the desired knit pattern.
Flat knitting machines:
They produce flat knitted fabrics. They are used to knit jumpers, blankets, and bed sheets. An interesting feature of flat knitting machines is that they can include hand-knitting options. These may also allow a combination of hand and auto operations.
Stranded colorwork knitting machines:
These machines create patterns by knitting with two or more yarns. They are also known as fair isle machines. They may be automatic or semi-automatic.
Specifications of automatic knitting machines may vary depending on the type of machine. Nonetheless, the main specifications include:
Fabric width:
This refers to the overall width of the fabric that an knitting machine can produce. The fabric width is a crucial specification, particularly when the machine's primary purpose is to manufacture fabric for garments or home textiles. Automatic knitting machines come in various fabric widths to cater to different end-use applications. Measuring the width from selvage to selvage can easily determine the fabric width.
Knitting speed:
This is the number of stitches or rows that the machine can produce in a minute. The knitting speed of an automatic knitting machine is higher than that of a manual one. The knitting speed varies depending on the type, model, and intended purpose of the machine. For instance, flat knitting machines produce an average of 30, 60, or 90 stitches per minute. On the other hand, circular machines have a higher knitting speed of about 300 to 600 RPM.
Control system:
Automatic knitting machines have varied control systems. The control systems can be computer-aided design (CAD) software for complex garment programming and knitting pattern creations or microprocessor-based controls for basic stitch settings and pattern variations.
An example of a control system in an automatic knitting machine is the electronic control unit. It is responsible for controlling the stitch formation, pattern selection, and machine operations. Also, it regulates the tension and feeding of the yarn to ensure uniform stitches. Other features include error detection, and digital display among others. This allows the operator to troubleshoot and identify any errors with ease.
Machine gauge:
The machine gauge refers to the number of stitches that can fit in a single inch of the knitting needle bed. It determines the fineness and width of the fabric produced. Higher knitting machine gauges create finer and more delicate fabrics, while lower gauges create heavier and coarser materials.
Power consumption
An automatic knitting machine's power consumption depends on various factors such as size, type, speed, and motor specifications. The power consumption may range from a few kilowatts to tens of kilowatts, depending on the above factors.
Automatic knitting machines require proper maintenance to ensure they operate efficiently and smoothly. The following are routine maintenance tips for an automatic knitting machine:
Regular cleaning:
It is important to remove lint and debris from yarns and fabrics during the knitting process. The knitting operations produce excess dust and debris that accumulates on the machine's parts. If not removed, this may affect the overall operation of the machine. Therefore, a regular cleaning schedule should be set to ensure the machine parts are spotless.
Lubrication:
Maintaining the knitting machine requires regular lubrication of the moving parts. This helps keep the machine running smoothly and reduces wear and tear. Lubrication also helps to minimize the knitting machine's power consumption.
Preventative maintenance:
It is important to establish a preventative maintenance schedule. This is because automatic knitting machines are complex, and their components can wear out or get damaged with time. Damage or wear may affect the machine's operation or its efficiency. Having a maintenance schedule helps indicate the parts of the automatic knitting machine that require repair or replacement prior to failure.
Massive Production:
Automatic sweater knitting machines excel at producing large quantities of knitted products in a short time frame, making them well-suited for businesses in the fashion industry or those that make functional clothing. High-efficiency automatic knitting machines for socks are also great for producing large volumes, as one machine can produce multiple socks on its cylindrical structure.
Consistent Quality:
The automatic knitting machine creates exactly the same product, giving it repeatability. This is great for making items like company sweaters with a logo on them or uniforms with specific patterns that have to be used all the time. When this machine is used, customers can be sure that they will get the same quality every time.
Customization:
Despite their mass production capability, many automatic knitting machines also allow for product customization. Enhanced models come with features such as pattern programming, color changing, and the ability to incorporate different types of yarn, all of which enable specific customizations to be made to the knitted product. As a result, automatic knitting machines can be used to create branded products for promotional purposes, limited-edition collections, or collaborations with specific designers.
Hands-Free Operation:
Automatic knitting machines for sweaters and other products often allow for hands-free knitting. This is made possible by features such as yarn feeding systems, stitch pattern selection mechanisms, and automated take-up and finishing processes. Because of this, users don't have to be there all the time, which lowers labor needs and makes knitting easier.
Overall, the efficiency and easy use that automatic knitting machines provide make it easy to meet different needs in the knitting business.
When choosing an industrial automatic knitting machine for purchase, a buyer should consider sourcing machines that manufacturers have made with a wide range of yarn materials, including cotton, wool, synthetic fibers, and blends. These will accommodate different fabrics. Again, buyers should look for knitting machines capable of handling various fabric types and structures. Such machines can make anything from standard jerseys and rib knits to more complex patterns like lace, jacquards, and textured fabrics.
It would help if buyers also looked for machines with user-friendly interfaces and good control systems. These allow easy setup, adjustment, and monitoring of the knitting process at all times. Buyers should also look for machines with efficient knitting speeds and production capacity. When combined, these two factors significantly increase output and, therefore, the profitability of the knitting process.
It would help if buyers also considered the flexibility and programmability of the machines. They should look for models that can easily adapt to changing production needs and allow easy pattern changes. Such models will have long lifespans and will be able to accommodate different market requirements with ease. Buyers should also get knitting machines with easy-to-access maintenance parts. These will make machine servicers' and operators' work easier and ensure that the automatic knitting machines stay in good condition throughout their lives.
Finally, buyers should choose automatic knitting machines that are compatible with a wide range of knitting attachments and accessories. Such machines will expand the machine's capabilities and will offer various knitting techniques to consumers.
