Shui Xing Home Textiles visits Hong Yang for a comprehensive learning and technical exchange on wool quilt manufacturing processes.

2025 On July 8, a group of 24 people from Mercury Home Textiles' e-commerce bedding, e-commerce kits, e-commerce quality control, and Shanghai teams visited Jiangsu Hongyang Plush Co., Ltd. (hereinafter referred to as "Hongyang") to learn about wool batting expertise and engage in technical exchanges. This exchange aimed to gain a deeper understanding of Hongyang's core capabilities in wool raw material processing, wool batting production processes, and quality control, reach a consensus on key quality indicators, deepen cooperation between the two parties, and jointly improve the quality of end-terminal wool quilt products.

‌ I. Exploring the Source: In-depth Analysis of Jubai Wool Carbonization Technology

At the first stop of the exchange, Hongyang Chairman and Jubai Wool General Manager Huang Yubing gave the Mercury team a detailed explanation of the secrets of wool carbonization processing:

‌ Lean Production Line: General Manager Huang introduced the overview of Jubai's two advanced carbonization production lines, personally led the team to visit the first fine wool carbonization line, and thoroughly explained the core processes and functions of raw wool pretreatment (washing, carbonization, bleaching, needle detection, and packaging) (washing removes grease, secretions, and other impurities; carbonization removes plant impurities), emphasizing the key role of these processes in restoring the whiteness, looseness, softness, and high elasticity of the wool.

‌ Strict Defect Control: At the workshop site, General Manager Huang gave a detailed explanation of the main defects in raw wool (such as skin-adhering wool, yellow residual wool, etc.) and identification points, and focused on demonstrating how to efficiently remove metallic impurities through a precise strong magnetic system (2 strong magnetic rollers, 8 strong magnetic belts) in the production process to ensure the purity of the raw materials.

Process Essentials: In the carbonization workshop, General Manager Huang explained in detail the scientific principles of the washing tank (using flat rake, rotary rake, and countercurrent washing principles to improve efficiency) and the carbonization process. He emphasized that Hongyang and Jubai work closely together to precisely control the acid concentration, temperature, and process parameters, striving to effectively remove grass and other impurities while minimizing damage to the wool fiber strength, feel, and elasticity. The process includes key steps such as soaking, acid impregnation, deacidification, baking, carbon neutralization, washing, and drying.

‌ Silk Finishing Empowerment: For high-end wool for filling, General Manager Huang conducted an in-depth analysis of the raw wool silk finishing process (scale removal rate, chlorination treatment, enzyme polishing, neutralization washing, fluffy finishing, and drying and shaping), especially how to significantly improve the fluffiness and compression resilience of wool through process optimization—this is one of the core advantages of Hongyang wool batting.

‌ Lean Grading: The Mercury team observed the strict manual grading process of raw wool: raw wool pre-selection → mechanical opening and impurity removal → fine grading on the manual sorting table → fluffy finishing → quality inspection → metering and packaging. The on-site demonstration of manually removing impurities such as paint wool highlighted Jubai's strict control over raw material quality.

II. Focusing on Production: Transparent Display of Hongyang Wool Batting Manufacturing and Quality Consensus

Subsequently, the Mercury team went deep into the Hongyang wool batting production workshop, conducted on-site inspections of the core manufacturing process, and conducted in-depth communication on quality control points:

‌ Core Production: Hongyang is fully producing Mercury's key e-commerce product—machine-washable wool quilts. In the workshop, manually prepared wool fibers are transported via conveyor belts into a cotton mixing box (containing spiked opening rollers), fully mixed, combed into thin sheets by combing rollers, and then laid into a net by a cotton auxiliary belt.

‌ Process Optimization: Hongyang uses a specific process for Mercury's products: the prepared wool sheets do not go through the ironing process, but directly undergo two needle-punching reinforcements, and then the edges are precisely cut according to the process size. Technical personnel from both sides conducted on-site exchanges on process details.

‌ Efficiency Improvement: The Mercury team pointed out that adding an automatic cotton weighing and mixing system to Hongyang's carding machine will help reduce raw material waste during the initial start-up and achieve more precise gram weight control. Hongyang's management attaches great importance to this suggestion and stated that it will continue to evaluate improvement plans.

‌ On-site Teaching: General Manager Huang Yubing accompanied the entire process, explaining in detail each process and core process parameters on the production line, patiently answering various technical questions from Mercury's engineers, and creating a lively atmosphere of on-site interaction.

‌ Quality Inspection Strengthening: ‌ ‌ Quality control is paramount.

‌

Under the on-site supervision of the Mercury team: the sensitivity of the needle detector used for Vans (Mercury) wool batting currently in production was rigorously tested (adjusted from level 4 to level 6). Hongyang promised to immediately adjust and ensure that the needle detection sensitivity meets Mercury's requirements, which are higher than national standards.

In the size inspection process, insect remains were found in some packages, and Hongyang ‌ responded immediately by requiring the installation of window screens in the relevant areas (as shown in the figure) to implement insect prevention measures on the same day. At the same time, regarding the fluctuation in the size of the wool sheets after leaving the machine (length deviation), Hongyang promised to optimize the process and folding method to ensure that the length deviation is controlled within ±5cm, guaranteeing the flatness of the finished product.

‌ Open Communication: After the visit, both parties held an efficient and practical exchange meeting in the meeting room. Hongyang shared its mature experience in controlling the smell of wool and clarified that the products returned due to odor in the previous Vans order were not produced by Hongyang. The two parties communicated one by one about the quality problems reported in Mercury's bulk goods, and Hongyang clearly recorded the improvement requirements and formulated a preliminary rectification plan.

III. Exhibition Looking to the Future

This in-depth investigation and exchange between the Mercury Home Textiles team and Hongyang showcased Hongyang's technical capabilities in raw wool processing and production, and highlighted both parties' shared pursuit of product excellence. Hongyang highly values the valuable suggestions and stringent requirements put forth by Mercury Home Textiles and will promptly implement corrective measures. Hongyang looks forward to further deepening technical cooperation and quality improvement with Mercury Home Textiles, jointly developing and producing higher-quality wool bedding products that better meet consumer needs, and consolidating both parties' leading position in the high-end wool quilt market.
