Disposable semi-durable nonwoven fabric and related method of manufacture |
摘要 |
A disposable semi-durable wipe is fabricated by fluid entanglement of a composite web including carded and randomized layers fabricated of a blend of at least 10% rayon and polyester fibers. Two sided entanglement of the web enhances interstitial binding of web fibers to provide a durable fabric in which void areas are well defined for improved conformability and absorbency. The fabric has a basis weight in the range of 45-70 gsy, uniform cohesive MD and CD grab tensile strengths of approximately 25 lbs/inch, and an MD/CD fiber ratio in the range of 2.5:1 to 1.5:1. An adhesive binder is applied to the fabric to provide an abrasion resistance feature.
