COLORED LOOP SUBSTRATE FOR RELEASABLY ATTACHABLE ABRASIVE SHEET MATERIAL |
摘要 |
A colored loop material suitable for use with a hook-and-loop fastening system, wherein the loop material includes a first fibrous nonwoven web having a first surface and a second surface and includes side by side bicomponent spunbond fibers in which the fibers have a melting point differential of at least about 15 DEG C and in which said bicomponent spunbond fibers are comprised of a polypropylene component including at between about 2 % to 4 % by weight of a coloring formulation, and a copolymer component. The first fibrous nonwoven web has a thickness of at least about 0.15 mm and a basis weight of at least about 20 grams per square meter; a pattern on the first surface thereof of continuous bonded areas defining a plurality of discrete unbonded areas formed by the application of heat and pressure, wherein individual fibers within the discrete unbonded areas have at least a portion thereof extending into and bonded within the continuous bonded areas; and a percent bonded area of from about 20 to about 50 percent. If desired, a film layer may be bonded to the second surface of the first fibrous nonwoven web. Alternatively, a second fibrous nonwoven web may be bonded or laminated to the second surface of the first fibrous nonwoven web. The loop material is particularly suitable for the preparation of a releasably attachable abrasive sheet material. |
