A method for measuring and analyzing the productivity of Angora rabbit is provided. Firstly, the Angora rabbit to be tested are simultaneously sheared at the age of 18 weeks, and are reared in a single cage to the age of 29 weeks according to standard conditions for test, and the individual consumption of Angora rabbit during the test period is recorded; secondly, the wool samples were sheared from the middle and upper part of the body side of the Angora rabbit with an electric wool clippers. The weight of the Angora rabbit, the weight of the wool sample, and the length of the wool fiber were measured and bagged for recording; in the third step, the wool fiber diameter of each wool sample was measured by fiber projection method; in the fourth step, the measured values were substituted into the given estimation formula.

This disclosure relates generally to the preparation of eco-friendly engineered fabric, and more particularly to terry fabric and variations thereof. In one embodiment, a terry fabric is comprised of a soluble fiber blend, blended with cotton fibers, where the soluble fibers are dissolved in a caustic or enzyme solution to create highly porous yarns.

The present invention involves a yarn composed of a mixture of at least two different fibers, being 1 to 90% of pet fur and 1 to 90% of polyester fibers and may also contain 1 to 90% of natural fibers or no, recycled or not. The yarn can be composed of a mixture of at least two different fibers, being 30 to 90% of pet fur and 40 to 80% of polyester fibers and may also contain 1 to 90% of natural fibers or not, recycled or not. The yarn may also include a mixture of at least two different fibers, being 40 to 80% of pet fur and 20 to 40% of polyester fibers and may also contain 1 to 10% of natural fibers or not, recycled or not. The textile yarn is composed of a mixture of at least 70% pet fur, 30% of a recycled polyester fiber.

This disclosure relates generally to a composite yarn comprising a core and an outer wrapping. The core comprises an alpaca fiber roving. The outer wrapping comprises a second fiber.

Systems and methods are presented for fabricating conductive protein-based yarns to produce textile-based supercapacitors (TSCs). Conductive wool yarns are created by coating wool yarn with Ti.sub.3C.sub.2T.sub.x MXene flakes, or by coating wool yarn in MXene@conductive-polymer composite material, such as MXene@polypyrrole (PPY) or MXene@polyaniline (PANI). In some examples, the conductive polymer (e.g., polypyrrole (PPY) or polyaniline (PANI)) is polymerized in the presence of MXene flakes to yield conductive-polymer-coated MXene flakes (MXene@conductive-polymer), and then this material is then used to coat wool yarn to yield a conductive protein-based yarn. MXene materials offer a high conductivity, but tend to oxidize quickly, while conductive polymers have a lower conductivity, but are more chemically stable and less likely to oxidize. As such, it is presently recognized that, by combining these materials, a chemically stable and highly conductive composite material is formed that can be used to coat yarns to make TSCs.
