Abstract
Nonwoven fabrics are provided that include a mechanically entangled blend of fibers comprising (a) post-consumer recycled polymer staple fibers (PCR-staple fibers) and (b) one or more additional fibers, in which the one or more additional fibers are different than the PCR-staple fibers. The PCR-staple fibers are mechanically entangled with the one or more additional fibers to define the nonwoven fabric.
Claims15
A nonwoven fabric, comprising:
- a mechanically entangled blend of fibers comprising (a) post-consumer recycled polymer staple fibers (PCR-staple fibers) and (b) a plurality of wettable staple fibers having a hydrophilic coated thereon;
- wherein the PCR-staple fibers are mechanically entangled with the a plurality of wettable staple fibers one of more additional fibers to define the nonwoven fabric.
The nonwoven fabric of 5, wherein the mechanically entangled blend of fibers comprises the PCR-staple fibers, the plurality of wettable staple fibers, and a plurality of cellulosic fibers, and wherein the nonwoven fabric comprises a component weight ratio between the PCR-staple fibers in grams per square meter of the nonwoven fabric, the plurality of wettable staple fibers in grams per square meter of the nonwoven fabric, and the plurality of cellulosic fibers in grams per square meter of the nonwoven fabric according to the formula A:
- B:
- C, wherein
- (i) ‘A’ represents the PCR-staple fibers in grams per square meter of the nonwoven fabric and comprises a value from about 0.2 to about 0.8;
- (ii) ‘B’ represents the plurality of wettable staple fibers in grams per square meter of the nonwoven fabric and comprises a value from about 0.2 to about 0.8;
- and
- (iii) ‘C’ represents the plurality of cellulosic fibers in grams per square meter of the nonwoven fabric and comprises a value from about 0.2 to about 0.8.
