Effect of Material-to-Liquor Ratio on Fastness Performance and Color Strength of Polyester/Cotton Blended Knitted Fabric Dyed by One-Bath Two-Stage Dyeing

Type: article
Abstract: This study investigated the effect of the material-to-liquor (M:L) ratio on the dyeing performance of a 65/35 polyester/cotton blended single jersey knitted fabric using a one-bath, two-stage dyeing process under laboratory conditions. The polyester component was dyed with disperse dyes at high temperature under acidic conditions, followed by reactive dyeing of the cotton component under alkaline conditions. Three different material-to-liquor ratios (1:8, 1:9, and 1:10) were evaluated to assess their influence on color fastness and shade characteristics. The washing fastness results showed good to excellent resistance to color change (rating 4–5) for all investigated dyeing conditions, indicating stable shade retention after laundering. Excellent staining resistance (4–5 rating) was observed against acetate, nylon, polyester, acrylic, and wool adjacent fabrics, while staining on cotton improved from 2–3 at 1:8 and 1:9 M:L to 3–4 at 1:10 M:L, suggesting reduced dye transfer at a higher liquor ratio. Dry rubbing fastness remained consistently good to excellent (4–5) across all dyeing conditions, whereas wet rubbing fastness improved from 2 at 1:8 M:L to 3 at 1:10 M: L.
