摘要: A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

Besides, the present invention further provides an alginate fiber comprising cannabidiol, and the preparation method and the use thereof. The cannabidiol powder in the spinning solution can be evenly dispersed in the alginate solution, so that the spinning solution of the present invention can be applied to wet spinning to form the alginate fiber comprising cannabidiol. The alginate fiber comprising cannabidiol has anti-oxidative, anti-bacterial, antiinflammatory, and anti-allergic abilities.
