MaterialSynthetic Filaments
Polyester / Nylon Blend Filament
Mixed synthetic filament
A polyester and nylon blend mixes two filaments in one fill, balancing nylon's springy wear with polyester's low water uptake and stable stiffness. It is used in dusting and household brushes, and performance depends on the blend ratio, so the recipe is kept fixed for repeat orders.
What is a polyester and nylon blend?
A mixed fill of polyester and nylon filaments, each about 0.10–1.0 mm across, combined in a set ratio in each tuft. The blend can mix diameters as well as polymers, to give a soft surface with a firmer core.
Where is it used?
In our range: Venetian blind cleaning brushes and ceiling fan cleaning brushes, where a soft, dust-holding fill has to keep its shape on long reaches.
Why blend two filaments?
Nylon brings bend recovery and wear life; polyester brings low water uptake and stable stiffness. Mixed, they give a fill that holds up in humid rooms and cleaning sprays without going limp, at a cost between the two.
What are its limits?
Performance depends on the blend ratio, and the heat limit depends on the components. Changing the recipe changes the brush, so for replacements the fill recipe is kept fixed.
What should you tell us?
The surface and dust, the feel you want, the brush and handle length, and, for repeat orders, the original sample so the blend can be matched.
Questions buyers ask about Polyester / Nylon Blend Filament
Why blend polyester and nylon in one brush?
To combine nylon's spring and wear life with polyester's stable stiffness in humid or damp conditions.
Does the blend ratio matter?
Yes. It changes the feel and behavior, so the recipe is kept fixed for repeat orders.
How hot can a blended fill get?
It depends on the components; the lower-rated filament sets the limit.

Dust Removal
Dust is moved, not dissolved, so the brush is chosen by what the dust is. Fine dense nylon or goat hair lifts fine dust without spreading it.
