Taking Customers as a Mirror, Hearing the Voice of Textile Future​

Jiangsu Rugao Chenxia Textile Yarn & Belt Co., Ltd., as a "Specialized, Refined, Characteristic and Innovative" enterprise in Jiangsu Province, has always focused on the R&D and innovation of special yarns and industrial textiles. Relying on the outstanding performance of its independently developed products in safety protection and aerospace fields, the company successfully entered the list of "Top 30 Competitive Enterprises in China's Industrial Textile Industry". Leveraging its advantages in the vertical industrial chain from fiber processing to high-end weaving, the company continuously promotes the technological iteration and upgrading of functional textiles, and has formed core competitive advantages in the field of high-end textile materials.​

01 Six-Year Cooperation​

Laying the Foundation for Intelligent Blending Demonstration​

Six-Year Cooperation​

In 2019, Rugao Chenxia launched its intelligent upgrading strategy and established in-depth cooperation with Qingdao Hongda. Facing the strict requirements of industrial textiles for cotton blending uniformity, Rugao Chenxia has successively introduced multiple sets of JWF1081 standard multi-component precision cotton blending machines and JWF1081A high-yield multi-component precision cotton blending machines. Through the application of these equipments, the blending ratio can be stably controlled within ±0.5%, which not only helps the enterprise continuously build an intelligent blending demonstration production line in East China, but also lays a solid quality foundation for applications in high-end fields.​

02 Prominent Pain Points​

Challenges Faced by Traditional Cotton Blending Methods​

Prominent Pain Points​

Industrial textiles have extremely high requirements for the uniformity of raw material mixing. However, traditional cotton blending methods (such as manual premixing and cotton bale disc mixing) have long had two core pain points:​

1. Insufficient cotton blending precision leading to product quality defects​

The proportion fluctuation of traditional cotton blending methods often exceeds 5%, resulting in uneven cotton blending, inaccurate cotton distribution, and severe deviation of blending ratio. This directly causes problems in subsequent processes, such as dyeing color difference, and the attenuation of protective performance of functional fabrics (e.g., flame-retardant protective clothing) due to uneven local fiber distribution. These issues not only keep the return rate high, but also affect the enterprise's competitiveness in the high-end market.​

2. Reliance on labor restricting efficiency and cost control​

Traditional processes are highly dependent on manual operations, requiring multiple skilled workers per shift for real-time adjustment, resulting in low production efficiency. In addition, manual cotton blending and cotton bale disc mixing have problems such as large floor space, frequent fiber beating, and uncontrollable mixing uniformity. They are difficult to adapt to the flexible production needs of small batches and multiple varieties, directly restricting the rapid improvement of enterprise benefits.​

03 Technological Breakthrough​

Achieving a Qualitative Leap through Precision and Intelligence​

Technological Breakthrough​

Qingdao Hongda's JWF1081/A series precision cotton blending machines address industry pain points with technological innovation and achieve breakthroughs through the core advantages of the equipment:​

1. Industry-leading cotton blending precision, effectively controlling quality fluctuations​

The JWF1081/A precision cotton blending machine adopts an independent support structure and a suspended weighing unit design, equipped with fully imported Mettler-Toledo (Switzerland) electronic scales. It uses an intelligent prediction and automatic compensation technology for weighing deviation based on a mathematical dynamic model, with a weighing precision of ±1%. This improves yarn strength and effectively solves the problem of blending ratio deviation caused by inaccurate manual cotton distribution.​

2. High degree of automation, significantly reducing labor reliance​

The JWF1081/A precision cotton blending machine can fully replace traditional cotton mixing/premixing processes, reducing labor demand by more than 50% compared with manual cotton blending. Its high-performance cotton feeding structure supports the feeding of multiple raw materials and increases the output to 700kg/h (1200kg/h for the high-yield model), significantly improving cotton blending efficiency. At the same time, the equipment adopts a flexible opening device, which effectively reduces the number of fiber beatings, avoids quality fluctuations caused by repeated operations, and effectively guarantees the final yarn quality.​

3. Strong spinnability, supporting efficient processing of multiple fibers​

The key components of the JWF1081/A precision cotton blending machine adopt anti-entanglement design, which can be adapted to pure cotton, colored cotton, various chemical fibers below 76mm, and long fiber raw materials such as wool that are easy to entangle. By optimizing the opening and large-capacity conveying structure, the equipment effectively avoids fiber entanglement and blockage, ensures continuous and stable production during the mixing of different raw materials, and significantly expands the range of raw materials for industrial textiles.​

Through the integration of precise weighing and automated processes, the JWF1081/A precision cotton blending machine not only ensures cotton blending uniformity, but also effectively helps enterprises address the core challenges of high labor costs and difficult quality control.​

04 Customer Recognition​

Practical Results Witness the Value of Technology​

Customer Recognition​

Regarding the product advantages of Qingdao Hongda, Sun Xiaojiang, Technical Director and Factory Director of Rugao Chenxia, has a deep experience. He stated that the JWF1081/A precision cotton blending machines used by the enterprise have significantly improved the accuracy of the blending ratio. On this basis, both production efficiency and yarn quality have been greatly improved. These changes have not only brought the enterprise a benefit growth of millions of RMB, but also further enhanced its competitiveness in the industry.​

Creating the Future with Intelligence, Jointly Building a New Height in Textiles​

From the first experimental line to a large-scale smart manufacturing base, Rugao Chenxia and Qingdao Hongda have jointly promoted the leap of cotton blending technology from "uniform mixing" to "precision functional proportioning". In the future, this "golden partner" will take joint technology research as the pen and win-win service as the ink, continue to write a new chapter of "exquisite craftsmanship creating Chinese quality" in the wave of high-end industrial textiles, and make "Made in China (Intelligent Manufacturing)" a core coordinate in the global special textile industry chain.
