About Milkweed Fibre

Milkweed Plant

Cross-sectional view

Soft, buoyant, lustrous floss is yellowish white in colour.

About 1 to 3 cm (0.375 to 1.12 inches) in length and 20 to 50 microns (0.0008 to 0.002 inch) in diameter.

It is a natural seed fibre mostly composed of Cellulose.

Used as fiberfill in comforters, personal flotation devices and upholstery.

Properties

Durability The alkali treatment of fibre results in a change of colour

from off-white to brownish yellow.

Develops convolutions after alkali treatment.

The bundle fibre strength and elongation of milkweed fibres is lower due to the absence of convolutions or crimp like structure.

The moisture regain of milkweed fibres is higher than cotton.

The milkweed fibre elongation is lower and short fibrepercentage is higher compared to cotton.

The raw milkweed fibres start degrading at around 180°C .

Aesthetics The milkweed fibres are finer, less dense and yellowish in colour when compared to cotton.

Lightweight, soft, hollow, buoyant, poor aging resistance.

Stain-resistance, and easy wash ability. It itself cannot be spun but can be mixed with other fibres. It is fire-resistant due to the high silica content of the fibre.

Comfort

It is a very shiny, slippery fibre with poor clinging ability.

It has poor dye acceptation capacity.

Poor elasticity.
