A process is described wherein pile yarn is woven with cotton weft and warp yarns to produce terry fabrics, such as towels. The fabric is then washed in warm water to dissolve the PVA fibers. The amount of fibers dissolved, depends upon the count of the yarn or yarns used. By dissolving the PVA fibers, a hollow air space is produced throughout the pile yarn, corresponding to an increase in the air space in the pile yarn. By increasing the air space in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels. The present invention further relates to pile yarn in terry woven fabric (warp yarn), or weft yarn, in the case of flat fabrics.

The problem to be solved is to provide an article that is capable of detecting position information within a building, and detecting hazards related to life such as heat stroke to issue an alarm, while ensuring safety, workability, and convenience. Means to solve the problem is an article including an alarm system, wherein the alarm system includes, a position information sensor, a three-axes acceleration sensor, a gyro sensor, a geomagnetic sensor, or a combination thereof; and a part configured to autonomously estimate a position from information emitted from the position information sensor, etc.

A method of making a yarn is disclosed. A plurality of fibers is obtained by: preparing a slurry of polymer mixed with water insoluble nanoparticles of electrolytic copper, and extruding the slurry through a spinneret that includes a plurality of holes which impart a generally X-shaped cross-section to the plurality of fibers. The plurality of fibers are spun together to form the yarn.

A cushion material 10 for hot pressing includes a cushion part 1. The cushion part 1 includes a woven fabric 5, in which a twisted yarn is used for at least one of warp 5a or weft 5b, and a polymer material 6 adhered to a surface of a fiber forming the woven fabric 5. The twisted yarn used for at least one of the warp 5a or the weft 5b of the woven fabric 5 is formed by twisting a plurality of texturized yarns made of glass fiber.

The invention relates to a fabric. The fabric (10) comprises, in the fabric material, threads (11a1, 12a1; 13a1, 14a1) of a material conducting electricity well, by means of which electro-magnetic radiation and magnetic fields are filtered. The threads (11a1, 12a1; 13a1, 14a1) are placed next to each other. Furthermore, the threads are wound around their winding axes (X1, X2; Y1, Y2) so that the first thread (11a1, 13a1) in the fabric is wound clockwise, and the second thread (12a1, 14a1) next to it is wound counterclockwise.

A woven terrycloth stretch fabric includes: weft yarns arranged along a first direction; first and second ground warp yarns arranged along a second direction, the first and second ground warp yarns being looped around the weft yarns with a first degree of tightness. Face loop warp yarns and back loop warp yarns are looped around the weft yarns with a second lesser degree of tightness, the ground warp yarns together with the weft yarns, together forming a base ground of the terrycloth stretch fabric. The plurality of face loop warp yarns and the plurality of back loop warp yarns each loop around the weft yarns so as to form front and back piles of the terrycloth stretch fabric. At least one of the ground warp yarns has a composite yarn comprising a cotton yarn having a polyolefin-based elastic yarn core.
