Animal fibers are natural fibers that consist largely of particular proteins. Instances are silk, hair/fur (including wool) and feathers. The animal fibers used most commonly both in the manufacturing world as well as by the hand spinners are wool from domestic sheep and silk. Also very popular are alpaca fiber and mohair from Angora goats. Unusual fibers such as Angora wool from rabbits and Chiengora from dogs also exist, but are rarely used for mass production.
High-count single-warp single-abb worsted plus single thread and processing method thereof
The invention discloses a high denier single spinning single yarn and the processing method. The yarn general branch is 35-60S / 1. The material is pure wool or the mixing yarn by wool and terylene, mucilage glue, nylon, the cashmere and floret. It selects the proper material and the using mass in process; also in strip dye and combing process, the animal fiber such as wool, cashmere and floret is dying in low temperature, but for terylene, it uses the dye water in 130deg.C to add the assistant agent in dye or back treat process. In spinning process, it uses the compact spinning or multi spinning to protect the wool fiber and improve the dye quality. So the single yarn has little feather and big strength, good elasticity and good abrasion resistance.

Shape Memory Polymer Mascara Brush
ActiveUS20100071715A1Uniform bristle quantityUniform orientationBristlePackaging toiletriesFiberBristle
A mascara brush head includes bristles made from shape memory polymer (SMP) filaments or fibers. The shape memory polymer filaments are selected to exhibit a first shape during assembly of the brush, and a second shape after exposure to an external stimulus in the form of heat or other energy. The brush head is initially assembled, i.e., lengths of SMP filaments are placed between wire segments and the wire segments are then twisted about each other to form a twisted wire core. The core grips the filament lengths medially of their outer ends, usually substantially at their midpoints, so as to clamp them. The first shape can be straight to facilitate assembly of the fibers in the wire core. The second shape, after assembly in the core and after being subjected to the external stimulus, can be any bristle shape suitable for enhancing the function of the brush, e.g., kinked, wavy or coiled. The brush head may be comprised solely of SMP filaments, or may be a blend of SMP filaments and any other suitable filament (e.g., nylon, natural plant or animal fibers, etc.).
