The modern textile industry is undergoing a massive transformation powered by digital integration, high-speed automated knitting, and precision software engineering. At the core of this paradigm shift is the development of robust, reliable machinery such as the SoosanSocksMachine series and the industry-leading RB computerized sock knitting systems. Shaoxing Rainbowe Machinery Co., Ltd., established in 2011, has been at the forefront of this industrial revolution, delivering specialized manufacturing hardware and high-precision components that support the competitive edge required by high-output mills worldwide.
To meet the diverse demands of global markets—spanning from heavy duty compression sportswear to intricate jacquard lifestyle patterns—our state-of-the-art RB series supports various customized specifications. We specialize in four primary computerized models: RB-6FP (Plain), RB-6FP-I (Invisible plain), RB-6FTP (Terry & Plain dual use), and RB-6FTP-I (Invisible terry & plain). Our control systems adopt high-speed processors that emulate and interact seamlessly with traditional Soosan-style mechanical alignments while offering modern user-friendly firmware.

Modern sock manufacturing requires absolute precision in tension control, needle selection, and speed regulation. Historically, older systems faced high yarn-breakage rates and complex pattern reset processes. Rainbowe has introduced significant mechanical improvements to alleviate these bottlenecks:
Equipped with an advanced high-speed computerized system supporting multiple languages natively—including English, Spanish, Arabic, and Russian. It permits easy pattern configuration without complex external software compilation.
Every small component inside our knitting cylinder, from needles (using reliable Feijian brand) to sinkers, undergoes heat treatment. This drastically reduces downtime and structural maintenance costs.
Fully electronic stepping motor drivers control the double-picker and double-knitter movements, making heel and toe formation seamless, improving stitch aesthetics, and ensuring dimensional uniformity.
Rainbowe's design philosophy targets **"Turning ideas into reality"**. No matter if you are producing high-performance compression sports socks, complex 3D jacquard patterns, child-size non-slip ankle socks, or industrial-grade safety gloves, the modular adaptability of our systems makes customized production efficient.
The global textile machinery market is consolidating towards vendors that offer turnkey, single-window solutions rather than raw hardware sales. Procurement managers in South America (e.g., Peru, Mexico), Europe (e.g., Portugal), Asia, and Africa are actively seeking systems that reduce supply chain complexity. To address this, Rainbowe offers structured solutions spanning entire factory setups:
At Rainbowe, mechanical sales are only the beginning of a long-term partnership. Our global service network ensures that downtime is minimized through structured remote assistance and robust warranty terms.
We provide a full 2-year warranty on mechanical parts and a 1-year warranty on all critical electronic systems. Replacement parts are stamped with the authentic "Rainbowe" seal, guaranteeing quality.
Connect with a senior engineer via live video calls. We troubleshoot mechanical alignments, software errors, or pneumatic problems directly with your team in real time.
Send our team images, dimensions, or physical samples of the socks you want to produce. We will design the chain program files for you, free of charge.
Clients are invited to visit our Shaoxing facility for comprehensive hands-on technical training. Learn maintenance, programming, and mechanical tuning from the people who build the machines.
Over the next five years, the development of intelligent textile mills will demand integration with IoT platforms. Rainbowe is currently developing cloud-connected systems designed to monitor individual machine efficiency, count output, and flag component failures automatically before they cause a production stoppage.
Additionally, we are focusing on improving material sustainability. By partnering with eco-friendly yarn manufacturers and optimizing needle paths, our machines minimize yarn waste during heel and toe trimming by up to 15%. Choosing Rainbowe is not just an investment in today's production capacity; it is a strategic decision for tomorrow's sustainable manufacturing standards.
Plain models (such as the RB-6FP) are optimized for thin, light, and everyday socks. Terry models (such as the RB-6FTP) feature dual-purpose sinker beds allowing the machine to knit both thick, padded terry loop socks (like athletic or thermal winter socks) and standard plain socks.
Every sock machine built by Rainbowe undergoes a mandatory 48-hour continuous stress test running at 330 RPM. This procedure guarantees all mechanical adjustments, solenoid configurations, and electronic components function perfectly under maximum load. Following this, actual sock-knitting tests are run using client-specified patterns.
We provide cylinder needle configurations ranging from 96N (for heavy winter socks or thick outdoor wool socks) up to 168N and 200N (for high-density, fine-dress premium socks). 144N is our most popular all-purpose configuration for school and standard athletic styles.
Yes, our casting and component manufacturing facility allows us to customize major parts with your logo or standard corporate design. We regularly act as a direct OEM supplier for international brands looking to run customized manufacturing systems under local compliance protocols.
