Figure 3 shows that for Reactive Yellow K-R and Reactive Yellow B-4RFN, with the increase of the concentration of alkali, the exhaustion and fixation levels gradually increased, after reaching the maximum value, the exhaustion and fixation levels decreased when the concentration of alkali was further increased. The trend of the change in exhaustion and fixation levels was similar, but the optimal amount of alkali was different, sodium carbonate was required 10 g/L and 15 g/L for the two dyes, respectively. So the sodium carbonate concentration was 10 g/L for reactive yellow K-R and 15 g/L for reactive yellow B-4RFN. This dead wood must be completely removed by rubbing it down to new sound wood. If outside, the wood can then be primed with Weathershield Exterior Preservative Primer followed by the Weathershield Undercoat& Gloss. Rotten wood Cause

After the fabric has been treated with thecolor fixing agent, during the drying process, the molecules of the color fixing agent will be cross-linked by reactive cross-linking groups into large molecules by themselves, and will form a protective film on the surface of the fabric fiber, so that the dye is wrapped around the fiber and the dye is not easy to fall off. Immediately massage the remaining mixture through the rest of your hair, to ensure the colourant is evenly spread.Immediately massage the remaining product through the rest of your hair, using gloved hands, to ensure the colourant is evenly spread.

The bleached yarns were dyed using two types of reactive dyes, reactive yellow K-R (with monofunctional groups) and reactive yellow B-4RFN (with bifunctional groups). Dyeing was carried out using different technique parameters at a bath to material ratio from 10:1 to 50:1 [10:1, 20:1, 30:1, 40:1, 50:1]. The dye concentration was 2% owf. The initial temperature of dyeing was 40 °C. Half the amount of sodium chloride (NaCl) was added after dyeing 5 min, the remaining salt was added in another 15 min. Fixing temperature maintained was from 60 to 90 °C [60, 70, 75, 80, 85, 90 °C], fixing time was adjusted to be from 20 to 60 min [20, 30, 40, 50, 60 min], alkali (Na 2CO 3) concentration was from 5 to 25 g/L [5, 10, 15, 20, 25 g/L], salt concentration was from 10 to 60 g/L [10, 20, 30, 40, 50, 60 g/L]. Alkali was added in batches. After dyeing, the yarns were soaped in 2 g/L soap powder and 2 g/L Na 2CO 3, and the liquor to material ratio was 30:1.
