A product having powder-like properties, the product comprising animal fibres, e.g. wool, having a length less than 10 mm, preferably less than about 3 mm, more preferably less than about 2 mm. Surprisingly, animal fibres having a length below a certain fibre length have powder-like properties, such as improved rheological properties, increased density, increased surface area and increased porosity. Also described are processes for preparing compositions and composites thereof, and uses thereof, e.g., as a filter aid, in a dietary supplement, in a filler and in a hair thickener.

Disclosed is a knitted fabric containing natural fibers and a making method therefor, a liquid ammonia device and a shirt made from the knitted fabric, belonging to the fields of fabrics and clothing. The making method for the knitted fabric containing natural fibers comprises forming yarns containing natural fibers into a knitted fabric by a fabric-knitting method; and performing functional finishing including a liquid ammonia finishing procedure on the knitted fabric. In the liquid ammonia finishing procedure, liquid ammonia impregnation is performed on the knitted fabric at least twice under the condition of mechanical restraint by a guide roller set, thus preventing the knitted fabric from edge curling due to strong shrinkage in the liquid ammonia impregnation process, enabling the knitted fabric to be subjected to sufficient and uniform liquid ammonia impregnation, ensuring the liquid ammonia impregnation effect and controlling the shrinkage rate of the knitted fabric; and through subsequent shaping and finishing procedures, the color stability of the knitted fabric is further improved, the shrinkage rate after washing is reduced, and the crease-resistant performance and resilience performance are improved. The shirt has a low shrinkage rate after washing, good stiffness performance, good resilience performance, color stability, high strength and good crease-resistant performance.
