Abstract:
Disclosed is a stitch-bonded string comprising at least one stitched line extending in a machine direction and fibers emanating from the at least one stitched line. The at least one stitched line comprises a plurality of loops and said plurality of loops enclose substantially all of said fibers. The stitched line is gathered to reduce a dimension of the plurality of loops holding said fibers within the loops. The stitched line's weight is less than 20%, preferably less than 10%, and more preferably less than 5% of the total weight of the stitch-bonded string. The fibers have a basis weight ranging between 30 and 400 grams/meter2, preferably between 40 and 350 g/m2, preferably between 50 and 300 g/m2 or between 100 and 250 g/m2. Methods for making the string are also disclosed.
