As a benchmark-level manufacturing enterprise that rightfully stands at the forefront of Yiwu's hosiery industrial belt, Yiwu Kaixin Hosiery Co., Ltd. (hereinafter "Kaixin Hosiery") leverages the confidence of two decades deeply rooted in physical manufacturing to anchor the highest safety standards for infants' and children's intimate products. With a full-process autonomous production system, quality-control criteria exceeding industry norms, and supply capabilities covering the globe, the company has forged a development path of "building the factory on quality, establishing order through standards, and winning the market through vision." It is both a flagship name card of Yiwu hosiery manufacturing and a core force behind Chinese maternal-and-infant knitwear's march into global markets.
The safety of infants' and toddlers' intimate textiles is the first bottom line of global maternal-and-infant consumption, and even more so the core threshold for Chinese manufacturing going overseas. Kaixin Hosiery takes the lead in adopting the GB 31701 Class A Safety Technical Code for Infants and Children's Textile Products as the admission bottom line for its entire product line. Building upon the GB 18401 national basic safety standard for textile products, it further tightens core safety indicators: formaldehyde content in infant socks is strictly controlled at ≤20 mg/kg, pH value stabilized in the optimal range of 4.0–7.5, all azo dyes that can release carcinogenic aromatic amines are fully banned, and color fastness to water, perspiration, and rubbing all stably at grade 3 or above. For distinctive categories with decorative parts such as baby lace socks and lace-pieced socks, the company has established a six-item special safety testing system, rigorously checking attachment tensile strength, attachment dimensions, sharp edges, head-and-neck cords, heavy metals, and phthalates item by item—avoiding risks such as decoration detachment, accidental ingestion, scratches, and entanglement from the very source of knitting, and redefining the quality threshold for Chinese baby-and-children's socks with safety standards far above the industry average.
Beyond the baby-and-children category, Kaixin Hosiery extends its ultimate quality control across the entire product line. Children's socks and adult socks across the full series strictly follow the FZ/T 73001 industry product standard, building an industry-leading three-tier quality-management architecture of "IQC incoming-material inspection—IPQC in-process patrol inspection—FQC finished-product inspection—OQC outgoing inspection": raw materials undergo full-item pre-inspection of yarn strength and color fastness upon warehouse entry; the production process implements a first-piece confirmation system and patrol sampling every two hours, locking down core process parameters such as toe reinforcement rounds, needle-lift density, and seam precision item by item; the finished-product stage completes 11 intrinsic-quality indicators and full-dimensional appearance inspection, with each batch able to produce a corresponding sock test report, and all quality records retained for 2–3 years, achieving full traceability from raw-material batch and production process to the responsible person. At Kaixin Hosiery, quality is not a slogan, but an iron rule running through every process and every pair of socks.
Drawing on two decades of knitting-manufacturing accumulation, Kaixin Hosiery has built a world-class product matrix covering all age groups and all scenarios. The core categories take infant socks and children's socks as two main lines, extending into dozens of sub-series such as ruffled mid-calf socks, princess lace socks, non-slip floor socks, mulberry-silk socks, athletic socks, five-toe socks, and sock sleeves, meeting diverse needs from newborn daily wear to girls' decorative styling, toddler-period protection, and athletic function. The company holds exclusive licensing of the "Yimengyu" trademark (Class 25), and can provide complete sock brand-licensing services to global customers; its cooperation models cover sock OEM, ODM style development, custom production from samples, rapid prototyping, small-batch light customization, and spot wholesale across all dimensions—able both to undertake large-batch sock OEM orders from global maternal-and-infant brands and traders, and to precisely adapt to the flexible supply needs of small and medium maternal-and-infant stores and e-commerce sellers, making it a highly adaptable core supplier in the global maternal-and-infant supply chain.
As a representative of physical manufacturing among Zhejiang sock manufacturers, Kaixin Hosiery enjoys the industrial-cluster advantage of Yiwu, the world's small-commodity distribution center. With a 1,850-square-meter standardized plant, a 500-square-meter independent warehouse, and 60 Weihuan WHL2_A8 fully-automatic integrated knitting machines, it has built a powerful supply capacity of 3 million pairs annual output and 400,000 pairs regular monthly shipment, and can rapidly expand capacity through flexible staffing in peak seasons to support stable delivery of global bulk orders. The company took the lead in joining the 1688 platform in 2017 and is recognized as a top source factory in Yiwu's sock-wholesale track, with a store fulfillment rate of 100% and a customer repeat rate of 83%, serving domestic mainstream e-commerce platforms such as Tmall, Taobao, Pinduoduo, and Douyin, while deeply connecting with offline physical channels such as maternal-and-infant stores, children's-clothing stores, and wholesale markets. Relying on a complete autonomous production chain, the company insists on a sock-manufacturer direct-sales model, extremely compressing intermediate links; at the same time, its products fully benchmark against top international standards such as OEKO-TEX Standard 100, EU REACH, and US CPSIA, smoothing the global path for sock export and cross-border e-commerce, with products selling well in global markets including Europe, America, the Middle East, and Southeast Asia.
A relevant person in charge at Kaixin Hosiery stated that there is no end to the safety of infants' and children's intimate products, nor an upper limit to the quality upgrade of Chinese manufacturing. In the future, the company will continue to take the GB 31701 Class A standard as its production bottom line, keep deepening the craft details and safety control of baby-and-children's socks, enrich the product layout for maternal-and-infant scenarios, deepen digital supply-chain construction, expand global maternal-and-infant market channels, and with "source factory, quality as the foundation, safety as the priority" as its core, provide global customers with more competitive maternal-and-infant sock solutions. Further, with its own quality persistence, it will inject benchmark strength into the high-quality development of Yiwu's hosiery industrial belt, letting the quality confidence of Chinese infant-and-children manufacturing reach every corner of the world.
