Abstract
Composite Alpaca yarn and a process for making same. The composite Alpaca yarn comprises special and unique characteristics created by blending long natural irregular Camelid fibers, such as Alpaca, with short synthetic fibers, or other natural fibers, in a combination determined by homogenization of fibers. The homogenization of fibers takes into account fiber lengths for twisting them with the use of high-pressure air blown nozzles, wherein Alpaca fiber is wrapped around an internal core. The face and surface of the composite Alpaca yarn, exhibit the fine characteristics of the Camelid fibers, including thermal isolation and impermeability, along with exceptional softness, wherein the Camelid fibers can be as fine as 18 microns.

Composite Alpaca yarn, comprising Alpaca fibers wrapped around an internal core, said internal core is made primarily of synthetic fibers, said Alpaca fibers are from an Alpaca, and said synthetic fibers are made of micro fibers of polyester or cellulose, said Alpaca fibers make up an exterior face by covering up to approximately 20% of said internal core.
A process for making Composite Alpaca yarn comprising Alpaca fibers wrapped around an internal core, said internal core is made primarily of synthetic fibers, said Alpaca fibers make up an exterior face by covering up to approximately 20% of said internal core, comprising the following steps:
- A) stretching Alpaca fibers having an Alpaca top count of approximately of 0.025 Ne, said stretching Alpaca fibers comprises drafting said Alpaca fibers 6 times, having a front roller distance of approximately 50 mm, having a back roller distance of approximately 54 mm, at a speed of approximately 280 meters per minute;
- B) breaking said Alpaca fibers from long lengths of approximately 70 millimeters to medium lengths of approximately 38 millimeters, whereby said Alpaca fibers are broken from said long lengths to said medium lengths, whereby raw said Alpaca fibers, enters through said back rollers and is drafted at least 6 times;
- C) collecting said medium lengths of said Alpaca fibers with a suction nozzle into a single fiber deposit;
- D) mixing said medium lengths of said Alpaca fibers with said synthetic fibers;
- E) carding said medium lengths of said Alpaca fibers and said synthetic fibers;
- F) drawing said medium lengths of said Alpaca fibers and said synthetic fibers a first pass after said carding;
- G) drawing said medium lengths of said Alpaca fibers and said synthetic fibers a second pass after said first pass;
- H) drawing said medium lengths of said Alpaca fibers and said synthetic fibers a third pass after said second pass;
- I) spinning said medium lengths of said Alpaca fibers and said synthetic fibers;
- and
- J) wrapping said medium lengths of said Alpaca fibers around said internal core.
