Abstract
A method and apparatus for producing continuous web or sliver of milkweed fibers without the use of conventional carding machines is disclosed. The method generally includes feeding raw materials including milkweed fibers into the apparatus, transferring the milkweed fibers to a sliver collecting net, and producing the slivers on the surface of the sliver collecting net. The slivers can be separated from the sliver collecting net.
Claims11
An apparatus to produce slivers of milkweed fibers comprising:
- an inlet configured to receive air and raw materials, the raw materials including milkweed fibers and impurity components, wherein the impurity components are heavier than the milkweed fibers;
- a blower fan, the blower fan being disposed along a top portion of the apparatus, the blower fan being configured to aerate the milkweed fibers by floating the raw materials;
- a sliver collecting net, wherein slivers of milkweed fibers are retained by the sliver colleting net as air exits the apparatus through the net, and wherein the impurity components pass through the sliver collecting net;
- and
- a plurality of gaps, wherein:
- the plurality of gaps are located along a bottom portion of the apparatus, and wherein the impurity components precipitate and pass through the plurality of gaps and the blower fan is configured to operate at approximately 2300 rpm and to aerate at a rate of approximately 210 m3/h.
