Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

Abstract: The present invention provides cured article reinforcing fibers having a shape advantageous in physically bonding the fibers to a hardening material or bringing the fibers into engagement with the hardening material, and also provides a cured article using the fibers. The cured article reinforcing fiber of the present invention has a multilobal cross section with three or more projections. At least one of the projections has a substantially curved end part, and a base part situated toward the center of the fiber has a width smaller than the largest width of the end part. Thus, the fiber particularly has high bending strength. Further, the cured article of the present invention includes a mixture of the cured article reinforcing fiber and a hardening material, and the hardening material has been cured.

Abstract: A process for producing a tapered multifilament yarn comprising feeding a drawable filament to a drawing apparatus and changing the take-over speed relative to the feed speed of the filament in order to change the thickness of the filament in a longitudinal direction, characterized by making the take-over speed slower than the feed speed under heating in a part of the filament in the longitudinal direction and thereby shrinking and thickening the part of the filament. According to the process, the ratio of the thickness of the thickest part of the tapered multifilament yarn to the thickness of the thinnest part thereof can be easily increased.

Abstract: An absorbent string comprising of a plurality of absorbent products. Each product has a tubular envelope. In use, the string is placed by the side of an appliance such as a freezer, whereby moisture from the appliance on the floor can pass through the envelope and be absorbed by the absorbent material.Each product has opposite ends that are complementarily shaped and are abutting with ends of adjacent products to form the absorbent string. The products have an elongate chevron shape. Each product has a double skin bottom and a single, folded top skin. Moisture on the floor can pass through the outer skin by capillary action into the product through the bottom. The absorbent material extends into the head and tail ends and up to the sealed periphery.
