대표청구항 ▼

1. An improved oil-absorbing article having a porous outer fabric which encloses fibrous absorbent particles, the improvement comprising the outer fabric being a nonwoven fibrous polyolefin layer of polyethylene or polypropylene that is stitch-bonded with an elastic thread that forms spaced apart rows of stitches extending along the length of the fabric, the row spacing being in the range of 2 to 10 rows per centimeter and the stitch spacing being in the range of 2 to 15 per centimeter, the stitching thread amounting to 2 to 40% of the total weight of the outer fabric and the outer fabric having a unit weight in the range of 30 to 250 grams per square meter. 2. An oil-absorbing article in accordance with claim 1 wherein the row spacing is in the range of 3 to 6 rows/cm, the stitch spacing is in the range of 3 to 10 stitches per inch, the stitching thread amounts to 5 to 10% of the total weight of the outer fabric, and the outer fabric has a unit weight in the range of 75 to 175 g/m 2 . 3. An oil-absorbing article in accordance with claim 1 or 2 wherein the thickness of the outer fabric is in the range of 0.6 to 1.2 mm and the density of the fabric is in the range of 0.1 to 0.2 g/cm 3 . 4. An oil-absorbing article in accordance with claim 1, 2 or 3 wherein the nonwoven fibrous polyolefin layer is formed of nonbonded, plexifilamentary, polyethylene film-fibril strands. 5. An oil-absorbing article in accordance with claim 1, 2 or 3 wherein the nonwoven fibrous polyolefin layer is formed of polypropylene fibers of no more than 3.5 dtex. 6. An oil-absorbing article in accordance with claim 1, 2 or 3 wherein the stitching yarn is a spandex elastomeric yarn. 7. An oil absorbing article in accordance with claims 1, 2 or 3 wherein the extensibility of the outer fabric is at least 75% in the longitudinal direction and at least 25% in the transverse direction. 8. An oil-absorbing article in accordance with claim 1, 2 or 3 wherein the fibrous absorbent particles include flash-spun linear polyethylene particles.
