A V-ribbed belt has a cord made of polyester-based fibers, the total fiber fineness of which is 2200 dtex or more and 5500 dtex or less. A fiber fineness of the cord per belt width corresponding to a single V-shaped rib ranges from 10000 dtex to 19000 dtex. A belt dry-heat shrinkage force per belt width corresponding to a single V-shaped rib is 44 N or more. The belt dry-heat shrinkage force is a load increase with respect to a belt length of 300 mm in 30 minutes after applying, in an atmosphere of 150 C., a load of 6N in the belt longitudinal direction and holding the belt.

Textile fibers and textiles produced from Brassica plants retain properties that are favorable for textile manufacture. Also described are textiles manufactured from the textile fibers produced from the Brassica plants which exhibit properties that are favorable for apparel and domestic applications, as well as industrial applications. Methods for producing the textile fibers from Brassica plants are further described.

A glove for use with capacitive touch screen devices features a main body portion, a finger portion and a thumb portion. At least the finger portion of the glove is constructed from a conductive and cut resistant yarn. The conductive and cut resistant yarn preferably includes a core that includes a cut resistant fiber and a sheath that include a conductive fiber.

A moisture-absorbing core-sheath composite yarn has a sheath polymer made of a polyamide, a core polymer is a polyetheresteramide copolymer, and the strength retention after a 150 C. 1-hour dry heat treatment is 50% or higher. The core-sheath composite yarn has high moisture-absorbing performance, is more comfortable than natural fibers, and can retain the soft texture, durability, and moisture-absorbing/releasing performance even when laundered and dried repeatedly.
