The invention relates to an elastic thread with limited elasticity, comprising: an elastic thread and a shaping layer combined with the elastic thread. The elastic thread itself has stretchable elasticity; the shaping layer is a high polymer material capable of dissolving in water. When the elastic thread is kept in a combined state with the shaping layer, an elasticity of the elastic thread is greatly reduced, and the elastic thread can be made into a textile, or used as an upper thread for sewing threads and embroidery threads, or as an upper thread for jacquard weave. When the shaping layer is dissolved, the elastic thread restores its original elasticity. The textile made with the elastic thread is soft and has stretchable elasticity.

An object of the present invention is to provide a method for efficiently manufacturing a protein crimped staple from protein filaments at a low cost. A manufacturing method for a protein crimped staple according to the present invention includes: a) preparing an artificial fibroin filament containing a modified fibroin; b) cutting the artificial fibroin filament to obtain an artificial fibroin staple; and c) performing crimping by bringing the artificial fibroin filament into contact with an aqueous medium to crimp the artificial fibroin filament before the cutting or bringing the artificial fibroin staple into contact with an aqueous medium to crimp the artificial fibroin staple after the cutting.

A method for producing shortened anionically modified cellulose fibers having an average fiber length of 1 m or more and 500 m or less, the method including cleaving sugar chains of anionically modified cellulose fibers by thermal decomposition under temperature conditions of 50 C. or higher and 230 C. or lower, wherein the average fiber length of the anionically modified cellulose fibers is 700 m or more and 10000 m or less. By the use of shortened anionically modified cellulose fibers or the like obtained by the method for production of the present invention, a dispersion containing fine cellulose fibers having a low viscosity and excellent handling property can be prepared while at a high concentration, so that the dispersion can be suitably used in various industrial applications such as daily sundries, household electric appliance parts, packaging materials for household electric appliances, automobile parts, and materials for three-dimensional modeling.

A method of manufacturing a sock including the steps of knitting the sock on a knitting machine with a first yarn, such as a cotton or polyester yarn, and a second yarn that is a silicone yarn wrapped with poly vinyl acetate (PVA) yarn. The PVA yarn substantially fully encapsulates the silicone yarn, with one PVA yarn being wrapped around the silicone yarn in a S twist pattern and the second PVA yarn being wrapped around the silicone yarn in a Z twist pattern. The sock is bathed in hot water after being knitted such that the PVA yarn dissolves and exposes the silicone yarn. The second yarn is knitted in the sock to form defined areas or patterns of silicone yarns within the sock, such as in the toe and heel areas. The resulting sock provides grip and slip-resistance properties on both the inside and outside of the sock.
