In the dyeing process of polyester-cotton (T/C) или polyester-viscose (T/R) blended fabrics, one challenge persists: polyester easily gets stained by reactive dyes used for the cellulosic part. This leads to visible contamination, poor fastness, and costly rework. To address this problem, we introduce a specialized solution — Polyester Resist Agent 23717 с сайта BLUELAKECHEM. This is a special polyester surfactant, specifically designed for the anti-dyeing of polyester fibers. It has a good effect on the active dyeing of cotton in polyester-cotton blended fabrics while leaving the polyester undyed.
Objective: Prevent Polyester Contamination in Blended Fabric Dyeing
Polyester, though hydrophobic, tends to physically adsorb reactive dyes during high-temperature processing. Without proper prevention, dye-stained polyester zones reduce product quality and color uniformity.
Lab Test Summary: Effective Protection with Polyester Resist Agent 23717
Test Setup:
- Fabric: White polyester half-bleached fabric
- Dye: blue reactive dye bath (simulating cotton dyeing)
- Test groups:
- No resist agent
- 1g/L of 23717
- 3g/L of 23717
- Process: Immersion in dye bath at standard conditions for 30 minutes
Observation (Post-dyeing):
| Dosage | Polyester Surface Result | Assessment |
| 0g/L (None) | Heavy staining | Failed |
| 1g/L | Slightly stained | Moderate protection |
| 3g/L | Clean and white | Excellent |
The 3g/L sample maintained a clean white surface, even under reactive dye bath conditions. The difference was highly visible and proved the agent’s effectiveness.
