Acid Nylonfix GD-GSF
| Properties | 1. Appearance : light brown liquid. 2. Chemical composition: Condensation compound of arylsulphonic acid hydroxyarylsulphone. 3. Ionic character : Anion. 4. Solubility : Dissolved in warm water. 5. pH : 8.5 ± 1 (1% water solution). 6. Stability: Stable in acidity (pH 4 - 5) and alkalescence solution, unstable in concentrated acid and cation copper salt, sediments will be emerged when using hard water and cation auxiliaries |
| Scope of application | 1. Enhance the wet fastness of acid dyes in nylon fiber and fabric. 2. Enhance the wet fastness of cationic dyes in modified nylon fabric. 3. Used to direct dyes in blended nylon / cotton fabric (N/C), nicer result of resist to nylon. |
| Characters | 1. This product is liquid, transport and load easily; dissolved in warm water, dilute and confect easilyand be used in production. 2. No changes of the color after fixing on the whole. 3. No foam when using. 4. No harmful effects to light fastness after using, and can improve water fastness, washing fastness, seawater fastness, perspiration fastness and so on. 5.Avoided white underside deep-dyed super to other products. |
| Applied method | 1. Enhance the wet fastness of acid dyes in nylon fiber. GD-GSF dosage: 1 ~ 3% (o.w.f). pH: 4.5 (adjusted by acetic acid). Temperature: 70 ~ 80°C.Time: 20 ~ 30 minutes. 2. Enhance the wet fastness of cationic dyes in modified nylon fabric. GD-GSF dosage: 1 ~ 3% (o.w.f). pH: 5 ~ 6 (adjusted by acetic acid). Temperature : 50 ~ 60°C. Time : 20 ~ 30 minutes. 3.Used direct dyes in N/C fiber, please consult the interrelated technics , made GD-GSF as nylon fiber resist. |
