Peach and Brushed Finishing: Creating a Soft Surface Skin
Peaching or sueding raises a fine surface fibre to create a soft touch, and the technique must be matched to the yarn and end use.
The practical guidance below is written for buyers and product developers who need a specification that a mill can meet.
How the surface is created
Abrasive rollers lightly raise fibre ends on the fabric surface, softening the hand and changing light reflection.
It is one of the few areas where a modest investment in development removes a large volume of after-sales work.
Effect on appearance and comfort
The surface becomes matte and velvety, which improves the perceived quality of synthetic knits.
Agree the tolerance in writing before sampling, since tolerance disputes are far more common than outright failures.
- Request test reports on production fabric, not on development samples
- Verify the sampling plan and the number of specimens
- Store reports with roll or lot identification for traceability
Yarn requirements
Peaching works best on spun or textured yarns; flat filament yarns give limited depth without fibre loss.
Escalate deviations immediately, as a small change early in the run is cheap to correct and costly to fix later.
Strength considerations
Aggressive treatment reduces fabric strength and can create pinholes on light weights.
Test at least three pieces per lot, because a single sample can easily fall on the good side of the average.
- Agree tolerances in writing before the first sample is made
- Define the measurement condition and the direction measured
- Review the limit each season against real performance data
Validation
Check hand feel, pilling, colour change and strength loss after the agreed number of passes.
Expect the cost and lead time implications to appear in sampling and capacity booking rather than in the yarn price alone.
Summary
The technical content is straightforward. The discipline lies in writing it down, testing it on production fabric and repeating the result on the next order.
