    摘要: Various implementations include a melt-spun filament that has a radial cross section that has two substantially parallel linear perimetrical sections and first and second curved perimetrical sections. The first curved perimetrical section extends between first ends of the linear perimetrical sections, and the second curved perimetrical section extends between second ends of the linear perimetrical sections. The curved perimetrical sections are convex. According to some embodiments, the curved perimetrical sections are semi-circular or semi-elliptical. A plurality of melt-spun filaments may be included in a bundle of filaments and/or a yarn made with the melt-spun filaments. In addition, a spinneret plate for spinning the melt-spun filaments and a method of making the melt-spun filaments is also provided.

    摘要: Various implementations include a mat having a lower surface and first and second edge portions that define at least a portion of a perimeter of the mat. The mat also includes a plurality of ribs that extend away from the lower surface of the mat for contacting the floor. Each rib has a longitudinal axis that extends between ends of the rib, and at least a portion of the plurality of ribs includes one or more branches that extend transversely to the longitudinal axis and are axially spaced apart from each other. The ribs are spaced apart from each other over the lower surface such that adjacent ribs define a valley therebetween. Water and/or debris can flow through the valleys. In addition, the longitudinal axis of each rib intersects the first and second edge portions of the mat at angles that are greater than 0° and less than 90°.
