When sourcing horse hair fabric (crinoline), you must evaluate the composition ratio, as it is often blended with cotton, silk, or polyester. For high-end upholstery or tailoring, a higher percentage of natural horse hair ensures superior breathability and structural memory. Check the warp and weft density; a tighter weave indicates better durability. Additionally, verify the width of the fabric, as natural horse hair length limits the loom width, typically ranging from 60cm to 70cm for traditional weaves.
