Organic Cotton Rib Knit Fabric
-- Steady & Reliable Manufacturer --
Overview
Our organic cotton rib knit is a vertically ribbed, stretchy knit fabric produced from OCS-certified organic cotton, offering the familiar stretch and recovery of rib construction with verified organic fiber content. It is a high-volume sourcing category for buyers producing T-shirt trims, fitted casualwear, underwear, and baby clothing where OCS transaction certificates at the fabric level are a procurement requirement.
Introduction
Rib knit fabric — characterized by its alternating vertical knit and purl columns — is one of the most functionally important knit constructions in apparel production. Its high two-way stretch and strong recovery make it the standard construction for T-shirt neckbands and cuffs, underwear waistbands, fitted tank tops, and any application where the fabric must stretch to fit and return to shape reliably. Produced in OCS-certified organic cotton, rib knit carries the performance profile of conventional cotton rib while substituting conventionally grown cotton with fiber certified to OCS standards — confirming the cotton was grown without synthetic pesticides, herbicides, or genetically engineered seed, addressing the growing demand from brand buyers and retailers for verified organic fiber content in high-skin-contact and baby product categories.
At Nantong Tianhong Textile Technology Co., Ltd., organic cotton rib knit is produced under OCS and OEKO-TEX® Standard 100 certification. We are one of the first manufacturers globally to adopt the OCS label for organic fiber products, and our certification infrastructure — independently audited by third-party bodies across the full supply chain — provides the verified documentation required by major retail sustainability programs. We supply this fabric to clothing factories requiring organic rib trims to match organic jersey or fleece bodies, brand owners developing certified organic basics and baby ranges, and wholesalers serving the growing OCS-certified knit fabric market. Optional spandex is available, with 15-day sample turnaround.
