Why It Matters
Natural cotton waxes, pectins and oils left on greige goods block wetting and cause uneven dyeing
Solution Approach
Natural cotton waxes, pectins and oils left on greige goods block wetting and cause uneven dyeing RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Processing Workflow
1
Substrate & Process Assessment
Identify the fiber and process stage (pretreatment, dyeing, finishing) and the performance, hand, and compliance targets.
2
Auxiliary Selection
Match surfactants, wetting and dispersing agents, softeners, fixatives, or pH and sequestering agents to the substrate and bath chemistry.
3
Lab Dip & Dosing
Confirm dose and sequence on a lab dip or pad trial, checking levelness, fastness, hand, and bath stability.
4
Production Validation
Verify reproducibility, fastness, and effluent compliance at scale, and set the recipe and packaging for production.
