For pad batch dyeing of tubular knitted fabrics of substantial cotton content. one or more connected strings of tubular knitted fabric (F) are advanced toward a dyeing apparatus, where the fabric is gripped across its full width and positively advanced toward the dye solution (120). A ring guide spreader (30) is positioned in close coupled relation to the driven entry roller (28) and spreads the fabric to flat form and to its natural greige width. Closely coupled to the ring guide means is a dye pad station comprising a pair of horizontally opposed resilient squeeze rollers (32, 33), a treating roller (34) forming a submerged dye nip with the front squeeze roller, and a submerged guide roller (35) to receive the fabric as it travels in a downward incline through the dye nip and redirect it to a vertically upward path for passage through the squeeze nip. The squeeze rollers (32, 33) are submerged in the dye liquor (120) to a depth less than half their diameter. |
