Colour Bleeding Solutions for Yoga Sets: Comparison of Options
Three working routes exist for colour bleeding in coordinated yoga sets. This page compares them by performance, cost and risk.
Option A: change the yarn
Changing fibre composition usually gives the largest improvement. It costs more and needs a new minimum quantity, but grade 4-5 colour change and staining is easier to hold over time. Because long holds put sustained rather than shock load on the fabric, target checks are made on a worn sample rather than flat fabric alone.
Option B: change the structure
Adjusting knit density is cheaper and faster. The trade-off is a narrower operating window, so process control becomes more important. Keep ISO 105-C06 washing fastness named in the tech pack so every lot is measured the same way.
Option C: change the finish
Finishing delivers fast results and can be added late. The risk is wash durability, so check performance after 10 and 20 washes. Where coordinated yoga sets is worn for studio practice and everyday wear, set tolerances around that range of movement.
Cost comparison
Indicative cost impact: extra soaping adds about 4 hours per batch. Testing adds little, while the cost of a rejected shipment is far higher. Any change to soft brushed jersey with 4-way stretch requires re-testing against grade 4-5 colour change and staining before bulk is released.
Recommended route
For studio practice and everyday wear the practical route is normally increase soaping at 90 degrees combined with use a fixing agent appropriate to the dye class. Confirm with ISO 105-C06 washing fastness before releasing bulk. Past reports from ISO 105-C06 washing fastness help the mill reproduce the same recipe on the next order.
