RFD

In textile production, RFD fabric is cloth that has been cleaned, scoured, and bleached but carries no color or finish. The term means the material is chemically and physically ready to receive dyes or pigments without further preparation. RFD goods arrive at the dye works in a neutral, absorbent state, typically on rolls or in rope form depending on weight and fiber type.

The RFD state represents the endpoint of preparatory processing: removal of sizing agents, waxes, oils, and impurities that protect fibers during weaving or knitting. Natural fibers like cotton and linen require scouring in alkali to strip out pectin and wax; synthetics need heat-setting correction and stabilization. The fabric must reach a consistent color value (usually very white or cream) and uniform wet-ability so dye liquor penetrates evenly across the entire piece.

Variants and specifications

RFD cloth varies widely by fiber content, weight, and structure. Cotton RFD fabric for apparel typically weighs 100 to 200 grams per square meter; heavier RFD canvas or twill for industrial textiles may exceed 400 gsm. Blended fabrics, wool goods, and technical textiles each have different RFD requirements. Some RFD materials are supplied with a temporary protective finish to prevent yellowing during storage; others are shipped as-prepared and must move to the dye vat within weeks to avoid oxidation or mildew.

Problems arise when RFD fabric has uneven water absorbency, residual alkalinity, or incomplete removal of lubricants from the loom. These faults cause streaking, uneven color uptake, and loss of depth in the dyed fabric. Temperature control and pH monitoring during preparation are critical to achieving consistent RFD quality across large batches.

The RFD classification is a handoff point in the supply chain: mills preparing fiber and weavers deliver RFD goods; dyers, finishers, and end-clothing makers receive and work with them. Documentation of RFD inspection (whiteness index, pH, moisture content) protects both supplier and buyer and prevents disputes over whether faults originated in preparation or in dyeing.
