Abstract The production of a high bulk cellulosic wadding product which involves the dampening, preferably to a well wet stage, of creped padding secured by adhesive in well spaced zones to a drawn synthetic fiber web. The drawn fiber is substantially unaffected by the dampening while release of crepe distends the tissue between adhesive zones providing a macrocrepe structure on the creped tissue, the bulked nature of the tissue being retained upon subsequent drying. The process most suitably is carried out on an assembly of cross-laid composites of the tissue and fiber. The product is characterized particularly by bulk, strength and softness and has utility in applications such as that of facecloths.
The process according to claim 1 in which, prior to dampening of the composite, two composites are cross-laid into a unitary assembly with the fibers in inner contacting layers and extending perpendicularly to each other, and the composites are then dampened in the form of the assembly to distend the outer wadding layers of the assembly.
Claim 2
Dependent Claim
25 words
The process according to claim 1 in which the creped wadding is subjected to a steaming to effect the dampening and distending of the wadding.
Claim 3
Dependent Claim
34 words
The process according to claim 1 in which the creped wadding during the distending process has a moisture content in excess of 100 percent by weight based on the dry weight of the wadding.
Claim 4
Dependent Claim
50 words
The process according to claim 1 in which the crepe ratio of the wadding and the dampening of the wadding between adhesive zones is such that the wadding distends so that the wadding length between adhesive zones is at least twice that of the straight line distance between adhesive zones.
