PFD (Prepared for Dye) is off-white and chemically treated to absorb dye; Optical White is bleached to a bright white finish; and Scour (Natural) is washed but unbleached, retaining its natural tan color. PFD (Prepared for Dye): This is an off-white fabric that has been treated with a small amount of bleach to create a "blank canvas" for dye absorption. It is the industry standard for custom dyeing or screen printing. Optical White (Bleach): This fabric has been bleached to a true, bright white (similar to printing paper). It is a finished product and does not require further dyeing. Scour / Natural: This fabric is finished to its natural tan hue. While it can be used as-is for an organic look, dyeing it requires special formula adjustments to counteract the natural yellow undertones.

French Terry is a knit fabric with loops on the back and a flat face, while Fleece is French Terry that has had the looped side brushed to create a soft, fuzzy texture. • French Terry: Characterized by its looped back and smooth jersey face. It is breathable and moisture-wicking, making it ideal for activewear. • Fleece: Derived from French Terry. The loops are mechanically brushed (napped) to break the fibers, creating a thicker, warmer, and softer insulation layer.

Knit fabric is made by looping a single yarn (like a T-shirt), making it stretchy and flexible. Woven fabric is made by interlacing two yarns (like a button-up shirt), making it more structured and rigid. • Knits (Made by Greene Textiles): Created by "interlooping" a single set of yarn. This structure allows the fabric to stretch and move with the body. Examples include Jersey, French Terry, Rib, and Thermal. • Wovens: Created by weaving two sets of yarn perpendicular to each other. These fabrics generally do not stretch and are often manufactured overseas. Examples include Denim, Poplin, and Flannel.

As a manufacturer, our custom production minimums are approximately 1,000 yards per style/color. However, we also offer in-stock fabrics with lower minimums for smaller businesses. Manufacturing (Custom): Because we start from raw materials (knitting, dyeing, and finishing to order), we require higher volume to ensure efficiency and competitive pricing. Manufacture vs. Retail: Unlike retailers who sell by the yard or wholesalers who sell small rolls (50-500 yards) with a markup, buying directly from a manufacturer like us offers the best value for brands scaling their production.

Greene Textiles uses "Ounces per Linear Yard" (oz/yd), which weighs a strip of fabric 36 inches long by the full width of the roll. Other common measurements include GSM (grams per square meter) and Oz/Sq Yard. • Ounces per Linear Yard (oz/yd): The weight of a piece of fabric that is 1 yard long (36") x the full width of the roll (e.g., 60"). This is the standard unit used at Greene Textiles. • Ounces per Square Yard (oz/sq yd): The weight of a 36" x 36" square of fabric. This number will always be lower than the linear yard weight. • Grams per Square Meter (GSM): The metric weight of a 1m x 1m square of fabric. This is the global standard for comparing fabric density.
