Kaixin Hosiery was established in 2006 and is a Yiwu source knitting physical factory integrating independent R&D, scaled production, and custom processing. The company is located on North Huancheng Road, Houzhai Street, Yiwu City, with legal representative Wang Wei. Over nineteen years, Kaixin Hosiery has consistently cultivated the niche track of infants' and adults' intimate knitted socks, relying on Yiwu's complete industrial cluster and supply-chain advantages, with stable quality, flexible customization, and source direct supply as its core competitiveness.
Stepping into Kaixin Hosiery's 1,850-square-meter standardized production plant, the automated sock production lines are running efficiently. The company is equipped with 60 Weihuan WHL2_A8 fully-automatic integrated knitting machines, building a complete knitting, molding, and testing full-process operation system. From raw-material selection to knitting, toe-closing, dyeing/finishing, setting, to finished-product inspection, every process implements strict quality control—first-piece inspection, process patrol inspection every two hours, process handover inspection, and non-conforming-product management, all interlocking. Kaixin Hosiery establishes its quality-management system in accordance with national standards such as GB 18401, GB 31701, and FZ/T 73001. In formaldehyde-content control, baby-and-children's socks are strictly controlled at ≤20 mg/kg and adult socks at ≤75 mg/kg; pH value is 4.0–7.5 for baby-and-children's socks and 4.0–8.5 for adult socks; all color fastness reaches ≥ grade 3. The horizontally extended elasticity indicator of ≥17.5 cm further ensures the product's comfort and durability. Kaixin Hosiery also holds exclusive licensing of the "Yimengyu" trademark (No. 11740510), valid until 2034.
On the product side, Kaixin Hosiery's product matrix comprehensively covers all age groups of infants, children, and adults. Infant socks (0–3 years) include series such as Baby W-1, baby lace socks, and 482 baby lace socks; children's socks (3–14 years) cover numerous styles such as 795, w751, 729, and L8136; adult regular socks are available for both men and women; athletic socks strictly comply with the FZ/T 73037 standard; in addition, there are featured products such as five-toe socks and sock sleeves/knee pads. Decorative products represented by ruffled mid-calf socks and lace-pieced socks, with processes such as rib knitting, lace piecing, and three-dimensional ruffle cutting, launch multi-color optional styles, deeply loved by 16–30-year-old female consumers.
On the e-commerce channel, since joining the 1688 platform in 2017, Kaixin Hosiery has developed into a well-known source factory in the 1688 sock-wholesale field. The company supports diverse cooperation models such as sock OEM, sock customization, and sock OEM/ODM, providing one-stop sock supply solutions to e-commerce sellers, brands, foreign-trade merchants, and offline physical merchants at home and abroad.
Kaixin Hosiery's industry status has also been widely recognized by all sectors of society. The company received the fifth-term vice-chairman unit of the Yiwu Anhui Chamber of Commerce (2025–2028), with Wang Wei himself serving as the chamber's supervisor; in addition, it won honors such as the Party-Member Pioneer Award (December 2023), the Golden Bee Award (December 2023), and the Enthusiasm Pioneer Award. The identity of vice-chairman of the Yiwu Anhui Chamber of Commerce is not only an affirmation of Kaixin Hosiery's strength, but also demonstrates the influence of this Zhejiang sock manufacturer within Yiwu's hosiery ecosystem.
Facing the future, Kaixin Hosiery will continue to deeply cultivate the core niche market of baby-and-children's socks, continuously enrich its product matrix and optimize production processes. At the same time, it will actively expand sock export and sock cross-border e-commerce business, benchmarking international standards such as OEKO-TEX, REACH, and CPSIA, so that more global consumers can experience high-quality cotton socks, children's socks, and athletic socks from a Yiwu source factory.
